Modifying the code

The user has a file drag-and-drop interface for Excel file uploads. The task involves modifying the existing interface to add more functionality. Specifically, they need two input boxes on the right side for "开始日期" (start date) and "设备" (equipment). These inputs should allow specific date and equipment options. After these are chosen, dragging a file should filter the Excel data based on the start date in column 12 and equipment in column 6.

Let me clarify the code changes needed.

Updating backend and frontend

The task requires filtering data based on a selected start date and equipment. For the frontend, we’ll add two input elements: one for the date and one for equipment, probably using a date input and a drop-down select. After the file is loaded, these selections will be included in the POST request to the backend. On the backend, the Python code in check_data needs to be updated to filter based on the 12th column for date and the 6th column for equipment. I’ll provide the necessary code updates for both.

Front-end and back-end modifications

For the front-end, we need to add two input fields: one date input for the start date and one select dropdown for equipment. This will be positioned on the right side of the page using a flexbox layout. I’ll update the handleFiles function to append these values to the FormData object when a file is uploaded.

On the back-end, the check_data function will need to accept the start date and equipment as parameters. It will then filter the data based on these criteria, ensuring the start date in column 12 is greater than or equal to the selected date and equipment in column 6 matches.

Code modifications and explanation

For the front-end, I added input fields for start date and equipment, placed them using a flex layout, and updated the handleFiles function to include these values in the FormData when uploading the file.

On the back-end, I modified check_data to accept start_date and equipment parameters, filter the data based on columns 12 (start date) and 6 (equipment), and align the data validation logic. The error handling remains the same for '铸锭总重量' and '熔炼总时长' in columns 2 and 10, respectively.

下面提供修改后的前端 HTML/JS 代码以及后端数据分析代码,满足以下要求:

  • 在页面右侧新增两个输入控件,一个用于选择开始日期(例如“2025-03-16”),一个用于选择设备(1#VIM、2#VIM、3#VIM、4#VIM);
  • 用户选择好开始日期和设备后,再次拖拽 XLSX 文件上传,前端通过 FormData 将文件、开始日期和设备一起传到后端;
  • 后端读取 Excel 后,先将第12列(开始日期)转换为日期类型、并对第6列(设备)筛选,只保留开始日期不早于所选日期且设备匹配的记录,再按照原有逻辑检查数据错误(例如:铸锭总重量 ≤ 0、熔炼总时长 ≤ 0)并返回结果。

前端代码修改

下面代码增加了一个容器,通过 flex 布局在标题右侧添加了两个输入控件,并在文件上传时将“start_date”和“equipment”随文件一起提交到后端:

后端代码修改

修改后的 Python 模块在接收到上传的文件后,同时传入选择的开始日期和设备,从而对 Excel 文件进行如下处理:

  1. 读取 Excel 文件;
  2. 将第12列(索引 11,对应“开始日期”)转换为日期格式,并将传入的开始日期转换为日期;
  3. 将数据筛选为:开始日期大于或等于所选日期且第6列(索引 5,对应“设备”)匹配所选设备;
  4. 对筛选后的数据进行错误数据检查(例如:铸锭总重量 ≤ 0、熔炼总时长 ≤ 0),并返回错误记录。

以下是更新后的 check_data.py 文件代码:

python
# functions/check_data.py import pandas as pd import os def check_data(file_path, start_date, equipment): try: # 读取 Excel,并获取所有列名 df = pd.read_excel(file_path, header=0) # 对第12列和第6列进行筛选: # 第12列:开始日期(索引 11) # 第6列:设备(索引 5) start_date_col = df.columns[11] equipment_col = df.columns[5] # 将 Excel 中的开始日期转换为日期类型 df[start_date_col] = pd.to_datetime(df[start_date_col], errors='coerce') # 解析用户传入的开始日期 start_date_parsed = pd.to_datetime(start_date, errors='coerce') if pd.isna(start_date_parsed): return {"error": "无效的开始日期"} # 筛选:仅保留开始日期大于等于所选日期且设备匹配的行 df = df.loc[(df[start_date_col] >= start_date_parsed) & (df[equipment_col] == equipment)] # 如果筛选结果为空,则返回空记录 if df.empty: return { "header": [], "rows": [] } # 以下为原有错误数据检查逻辑: # 获取所需的列名 col1_name = df.columns[0] # 第1列,炉号 col2_name = df.columns[1] # 第2列,铸锭总重量 col10_name = df.columns[9] # 第10列,熔炼总时长 # 筛选错误数据: wrong_1 = df.loc[df[col2_name] <= 0, [col1_name, col2_name]] wrong_2 = df.loc[df[col10_name] <= 0, [col1_name, col10_name]] # 整合错误记录为列表,每一记录形式为 [炉号, 错误列, 错误数据] rows = [] for _, row in wrong_1.iterrows(): rows.append([row[col1_name], col2_name, row[col2_name]]) for _, row in wrong_2.iterrows(): rows.append([row[col1_name], col10_name, row[col10_name]]) return { "header": [col1_name, "错误列", "错误数据"], "rows": rows } except Exception as e: return {"error": str(e)} finally: # 删除临时文件,防止文件堆积 if os.path.exists(file_path): os.remove(file_path)

说明

  • 前端部分:
    • 在标题右侧添加了一个 .filter-container 容器,其中包含“开始日期”输入(类型设为 date,初始值设为 2025-03-16)和“设备”下拉框(包含四个设备选项)。
    • 在文件上传时,除了上传文件,还将这两个参数通过 FormData 一同提交给后端。
  • 后端部分:
    • 修改后的 check_data 函数增加了两个参数 start_dateequipment
    • 先将 Excel 文件中第12列(开始日期)转换为日期格式,再用传入的开始日期进行比较,同时对第6列(设备)进行匹配筛选。
    • 筛选后的数据再执行原有的错误数据检测,并返回表头及错误记录列表。

将前端与后端代码分别更新后,就能实现选择开始日期和设备,上传后仅核对满足条件数据的功能。

Modifying Flask code

Alright, the user asks to modify the main program to incorporate additional parameters, "start_date" and "equipment," alongside the previous functionality. I'll need to adjust the /upload_data_check function to accept these parameters.

In the current setup, I might pass them as part of the request data. I also have to update check_data in check_data.py to work with these new parameters.

Alright, let me modify the existing code to include these changes. I'll update the file processing and include passing those extra parameters correctly.

Updating file handling and function calls

Alright, I need to update the /upload_data_check route to accept the start_date and equipment parameters. I can get them from request.form.get() and pass them along to check_data.

The function call should be like: result = check_data(save_path, start_date, equipment).

Since check_data already handles file deletion, I might not need to do that in the main program's "finally" block. I’ll keep the file check in place to ensure it doesn’t get deleted twice.

I can combine these changes and keep the secure_filename usage as is.

下面给出完整的 Flask 主程序代码及修改后的后端数据分析代码,前端 HTML/JS 部分不变(参考前一段代码),实现如下功能:

  • 用户在页面上选择“开始日期”和“设备”后上传文件,前端通过 FormData 同时提交这两个参数和文件。
  • 后端在接收到文件后,将文件保存到临时路径,再获取“start_date”和“equipment”参数;
  • 后端调用修改后的 check_data 函数,对 Excel 文件的第12列(开始日期)和第6列(设备)进行筛选,只保留开始日期不早于所选日期且设备匹配的记录,再检测错误数据(例如:铸锭总重量 ≤ 0、熔炼总时长 ≤ 0)后返回结果;
  • 最后将检查结果以 JSON 格式反馈前端。

下面是完整代码示例:


1. Flask 主程序(例如 app.py)

python
from flask import Flask, render_template, request, jsonify from werkzeug.utils import secure_filename import os from functions.check_data import check_data # 引入修改后的数据检查函数 app = Flask(__name__) @app.route('/data_check') def data_check_page(): # 直接渲染 data_check.html 页面(前端代码包含筛选控件) return render_template('data_check.html') @app.route('/upload_data_check', methods=['POST']) def upload_data_check(): save_path = None try: file = request.files.get('file') if not file: return jsonify({"error": "No file uploaded"}), 400 filename = secure_filename(file.filename) save_path = os.path.join("/tmp", filename) file.save(save_path) # 获取前端传入的开始日期和设备 start_date = request.form.get('start_date') equipment = request.form.get('equipment') # 调用 check_data 函数,并传入文件路径、开始日期和设备 result = check_data(save_path, start_date, equipment) if "error" in result: return jsonify(result), 500 return jsonify(result) except Exception as e: return jsonify({"error": str(e)}), 500 finally: if save_path and os.path.exists(save_path): os.remove(save_path) if __name__ == '__main__': app.run(debug=True)

2. 后端数据分析代码(functions/check_data.py)

python
import pandas as pd import os def check_data(file_path, start_date, equipment): try: # 读取 Excel,并获取所有列名 df = pd.read_excel(file_path, header=0) # 对第12列(开始日期)和第6列(设备)进行筛选: # 注意:Excel中列索引从0开始,所以第12列为索引 11,第6列为索引 5 start_date_col = df.columns[11] equipment_col = df.columns[5] # 将 Excel 中的开始日期转换为日期类型 df[start_date_col] = pd.to_datetime(df[start_date_col], errors='coerce') # 将传入的开始日期解析为日期格式 start_date_parsed = pd.to_datetime(start_date, errors='coerce') if pd.isna(start_date_parsed): return {"error": "无效的开始日期"} # 筛选:仅保留开始日期大于等于所选日期且设备匹配的记录 df = df.loc[(df[start_date_col] >= start_date_parsed) & (df[equipment_col] == equipment)] # 如果筛选结果为空,则返回空记录 if df.empty: return { "header": [], "rows": [] } # 以下为原有的错误数据检查逻辑: # 假设第1列为炉号,第2列为铸锭总重量,第10列为熔炼总时长 col1_name = df.columns[0] # 炉号 col2_name = df.columns[1] # 铸锭总重量 col10_name = df.columns[9] # 熔炼总时长 # 筛选错误数据: wrong_1 = df.loc[df[col2_name] <= 0, [col1_name, col2_name]] wrong_2 = df.loc[df[col10_name] <= 0, [col1_name, col10_name]] # 整合错误记录为列表,每条记录形式为 [炉号, 错误列, 错误数据] rows = [] for _, row in wrong_1.iterrows(): rows.append([row[col1_name], col2_name, row[col2_name]]) for _, row in wrong_2.iterrows(): rows.append([row[col1_name], col10_name, row[col10_name]]) return { "header": [col1_name, "错误列", "错误数据"], "rows": rows } except Exception as e: return {"error": str(e)} finally: # 删除临时文件,防止文件堆积 if os.path.exists(file_path): os.remove(file_path)

3. 前端页面(data_check.html)

前端页面代码参考之前的 HTML/JS 示例,其中包含页面右侧的“开始日期”和“设备”输入控件,并在文件上传时通过 FormData 传递这两个参数。


说明

  • 前端部分:
    页面在标题右侧新增了两个输入框,使用 HTML 的 <input type="date"><select> 标签,分别用于选择开始日期(默认值为 2025-03-16)和设备(1#VIM、2#VIM、3#VIM、4#VIM)。文件上传时,利用 FormData 将文件及这两个参数一同传至后端。

  • 后端部分:
    /upload_data_check 路由中,除了保存上传的文件外,通过 request.form.get 获取前端传来的 start_dateequipment 参数,并传递给 check_data 函数进行数据筛选。
    check_data 函数中,先对 Excel 文件中第12列(开始日期)转换为日期格式,再将用户选择的开始日期解析为日期,最后筛选出开始日期大于等于用户选定日期并且设备匹配的记录,接着执行错误数据检测逻辑,最后返回错误记录。

将以上代码分别更新到你的 Flask 项目中,即可实现所需功能。

Optimizing backend code

I'm given a query to simplify and optimize backend code — the provided code checks for multiple errors (like weight <= 0) and has repeated structures. Based on the client's request, they want the code to be cleaned up and restructured. So, I need to look into ways of combining these error checks into a single approach instead of repeatedly checking each error condition separately. It’s about reducing redundancy while maintaining logic. I'll start by grouping similar checks together to simplify the logic flow.

Optimizing error checking logic

Looking at the provided code, there's a lot of repetition in how error conditions are handled and assembled. For instance, data is filtered into "wrong" variables then iterated over to compile errors, which feels repetitive. I definitely want to streamline that. One way would be to combine similar checks with a loop over a list of conditions, like checking if values are less than or equal to zero. I can generalize error handling for types that share this pattern, simplifying the final assembly of error reports really effectively.

Optimizing error condition handling

The current error checking has redundancy, especially with column comparisons and error messages. I can approach this by creating a list of error conditions that use tuples or dictionaries to define the condition (like df[col] <= 0 or df[col18] >= df[col20]) and the column involved. The error rows are then appended by iterating through each condition once, simplifying the code and reducing repetition. I don't need a separate function for appending rows — a straightforward for-loop works fine here. I'll organize the structure for clarity and efficiency.

# functions/check_data.py import pandas as pd import os def check_data(file_path, start_date, equipment): try: # 读取 Excel,并获取所有列名 df = pd.read_excel(file_path, header=0) # 对第12列(开始日期,索引 11)和第6列(设备,索引 5)进行筛选 start_date_col = df.columns[11] equipment_col = df.columns[5] # 将 Excel 中的开始日期转换为日期类型,并解析用户传入的开始日期 df[start_date_col] = pd.to_datetime(df[start_date_col], errors='coerce') start_date_parsed = pd.to_datetime(start_date, errors='coerce') if pd.isna(start_date_parsed): return {"error": "无效的开始日期"} # 筛选:仅保留开始日期大于等于所选日期且设备匹配的行 df = df.loc[(df[start_date_col] >= start_date_parsed) & (df[equipment_col] == equipment)] # 如果筛选结果为空,则返回空记录 if df.empty: return { "header": [], "rows": [] } # 获取所需的列名 col1_name = df.columns[0] # 炉号 col2_name = df.columns[1] # 铸锭总重量 col10_name = df.columns[9] # 熔炼总时长 col18_name = df.columns[17] # 流槽转移时间 col20_name = df.columns[19] # 浇注开始时间 col21_name = df.columns[20] # 浇注结束时间 # 定义错误条件,格式为 (错误列, 条件 mask) error_conditions = [ (col2_name, df[col2_name] <= 0), # 错误1:铸锭总重量为0(或负数) (col10_name, df[col10_name] <= 0), # 错误2:熔炼时长为0或负数 (col18_name, df[col18_name] >= df[col20_name]), # 错误3:流槽转移时间>=浇注开始时间 (col20_name, df[col20_name] >= df[col21_name]) # 错误4:浇注开始时间>=浇注结束时间 ] # 遍历每个错误条件,将错误记录统一添加到 rows 中 rows = [] for error_col, condition in error_conditions: for _, row in df.loc[condition].iterrows(): rows.append([row[col1_name], error_col, row[error_col]]) return { "header": [col1_name, "错误列", "错误数据"], "rows": rows } except Exception as e: return {"error": str(e)} finally: # 删除临时文件,防止文件堆积 if os.path.exists(file_path): os.remove(file_path)

说明

  1. 筛选条件部分:

    • 将 Excel 文件中第12列(开始日期)转换为日期类型,并将传入的开始日期也转换为日期。
    • 使用 Pandas 的布尔索引同时筛选出开始日期大于等于用户选定日期、且设备匹配的行。
  2. 错误数据判断优化:

    • 通过构造列表 error_conditions,每个元组包含需要检测的错误数据的列名和对应的条件 mask,从而避免了多次重复的 for 循环代码。
    • 遍历列表对每个条件进行筛选,并将符合条件的记录以 [炉号, 错误列, 错误数据] 的结构添加至结果列表中。
  3. 异常处理与文件清理:

    • 使用 try/except 捕获异常,并在 finally 中清理临时文件。

这种写法结构清晰、易于维护,如果以后有新的错误判断条件,只需将条件以相同格式添加到 error_conditions 列表中即可。

Fixing error special condition

It looks like the special error condition is incorrect because the expression df[col34_name] > 2 and col6_name == "2#VIM" will return a boolean, not a boolean mask (Series).

I should instead create a boolean mask for both conditions, like this: (df[col34_name] > 2) & (df[col6_name] == "2#VIM"). This way, it will return a mask that can be applied to the DataFrame for filtering.

So, I’ll rewrite the error_special properly to:

python
error_special = [ (col34_name, (df[col34_name] > 2) & (df[col6_name] == "2#VIM")), ]

Clarifying special error condition

Okay, col6_name is just the column header, so it's not the value in the row. The actual device value is in df[equipment_col]. The user's request says this special check is for “4#VIM,” but the code checks for “2#VIM.” Hmm, so maybe the special check should be for the "2#VIM" device, where we compare the leakage rate (col34_name) with 2. The check should be like this: (df[equipment_col] == "2#VIM") & (df[col34_name] > 2) to produce a boolean series for filtering.

Optimizing special error condition

The current code incorrectly checks col34_name > 2 and col6_name == "2#VIM" which is not vectorized and uses the wrong column for the device. To fix this, I’ll need to update error_special to check against the correct column, df[equipment_col]. The goal is to apply the condition to "4#VIM," not "2#VIM." So, I’ll define the condition properly as (df[equipment_col] == "4#VIM") & (df[col34_name] > 2). I also need to consider possibly adding the logic for other devices like "1#VIM" or "3#VIM."

下面的代码对错误条件部分做了优化处理,同时对“特殊错误条件”只在设备为 "4#VIM" 时施加额外判断,从而避免原来的错误(原代码中错误地使用了非向量化逻辑以及错误数据类型进行判断)。具体实现思路如下:

  1. 首先按照原有逻辑读取 Excel 文件,并根据第 12 列(开始日期)和第 6 列(设备)筛选出符合条件的行。
  2. 接着定义一个包含常规错误判断条件的列表,每个错误条件以元组形式保存:(错误数据所在列名, 对应的布尔型条件 mask)。
  3. 对于需要特殊处理的情况(这里要求仅针对 "4#VIM" 数据,对“2#VIM和4#VIM漏率”列(col34_name)进行检查),判断传入的设备是否为 "4#VIM",如果是则将该条件以向量化的方式附加到条件列表中。
  4. 最后统一遍历所有错误条件,生成错误记录列表。

以下是优化后的完整代码:

python
# functions/check_data.py import pandas as pd import os def check_data(file_path, start_date, equipment): try: # 读取 Excel,并获取所有列名 df = pd.read_excel(file_path, header=0) # 对第12列(开始日期,索引 11)和第6列(设备,索引 5)进行筛选 start_date_col = df.columns[11] equipment_col = df.columns[5] # 将 Excel 中的开始日期转换为日期类型,并解析用户传入的开始日期 df[start_date_col] = pd.to_datetime(df[start_date_col], errors='coerce') start_date_parsed = pd.to_datetime(start_date, errors='coerce') if pd.isna(start_date_parsed): return {"error": "无效的开始日期"} # 筛选:仅保留开始日期大于等于所选日期且设备匹配的行 df = df.loc[(df[start_date_col] >= start_date_parsed) & (df[equipment_col] == equipment)] # 如果筛选结果为空,则返回空记录 if df.empty: return { "header": [], "rows": [] } # 获取所需的列名 col1_name = df.columns[0] # 炉号 col2_name = df.columns[1] # 铸锭总重量 # col6_name = df.columns[5] # 设备(此处不用,因为设备数据在 equipment_col 中) col10_name = df.columns[9] # 熔炼总时长 col18_name = df.columns[17] # 流槽转移时间 col20_name = df.columns[19] # 浇注开始时间 col21_name = df.columns[20] # 浇注结束时间 col34_name = df.columns[33] # 2#VIM和4#VIM漏率 col35_name = df.columns[34] # 1#VIM和3#VIM漏率 # 定义常规错误条件,格式为 (错误列, 条件 mask) error_conditions = [ (col2_name, df[col2_name] <= 0), # 错误1:铸锭总重量为0或负数 (col10_name, df[col10_name] <= 0), # 错误2:熔炼总时长为0或负数 (col18_name, df[col18_name] >= df[col20_name]), # 错误3:流槽转移时间>=浇注开始时间 (col20_name, df[col20_name] >= df[col21_name]) # 错误4:浇注开始时间>=浇注结束时间 ] # 针对特殊情况:仅当设备为 "4#VIM" 时,对漏率数据进行检查 # 这里检查 "2#VIM和4#VIM漏率" 列,如果其值大于2,则视为错误 if equipment == "4#VIM": error_conditions.append((col34_name, df[col34_name] > 2)) # 遍历所有错误条件,将错误记录统一添加到 rows 中 rows = [] for error_col, condition in error_conditions: for _, row in df.loc[condition].iterrows(): rows.append([row[col1_name], error_col, row[error_col]]) return { "header": [col1_name, "错误列", "错误数据"], "rows": rows } except Exception as e: return {"error": str(e)} finally: # 删除临时文件,防止文件堆积 if os.path.exists(file_path): os.remove(file_path)

说明

  • 常规错误条件:检查铸锭总重量、熔炼总时长、流槽转移时间和浇注时间的合理性,都通过向量化布尔运算获得条件 mask。
  • 特殊错误条件
    • 在原来的错误条件中,错误地使用了表达式 df[col34_name] > 2 and col6_name == "2#VIM",这里的问题有两个:
      1. and 用于标量布尔值,不能直接用于 Pandas 的 Series 对象;
      2. col6_name 是列名,不是每一行的值。
    • 优化处理时,由于上传前端已经根据设备筛选了数据,因此只需判断传入的设备参数。如果设备为 "4#VIM",直接添加 (col34_name, df[col34_name] > 2) 这一向量化条件即可。
  • 遍历错误条件:统一对每个条件 mask 进行过滤,并将符合条件的记录以 [炉号, 错误列, 错误数据] 的格式添加到结果列表中。

这样既避免了重复代码,也能正确对特殊条件施加判断,满足了你对代码优化的要求。

从你的代码描述中,似乎希望排除 col34_name 等于 0 的情况,但在逻辑判断时,条件语句没有按照预期正确组合,从而导致 col34_name == 0 的情况仍然被包含在内。

问题的原因是条件语句中 if equipment == "2#VIM" or "4#VIM" and df[col34_name] > 5 or df[col34_name] <= 0 这部分存在逻辑错误。"4#VIM" 和其他条件没有被正确组合,导致它始终被认为为 True

修正方法

  1. 条件组合问题
    需要使用括号来明确运算顺序,确保设备检查和漏率条件正确组合。

  2. 排除 col34_name == 0 的情况
    应确保在添加错误条件时,将 col34_name == 0 的情况从条件中排除。

关键修正和优化:

  1. 条件逻辑修正:

    • if equipment == "2#VIM" or "4#VIM" and df[col34_name] > 5 or df[col34_name] <= 0 这行的逻辑存在问题。修正为:
      python
      if equipment in ["2#VIM", "4#VIM"]: error_conditions.append((col34_name, (df[col34_name] > 5) | (df[col34_name] <= 0)))

    这样就可以保证只有设备为 "2#VIM" 或 "4#VIM" 时,才会检查 col34_name 的漏率。

  2. 漏率检查逻辑:

    • 对于 col34_namecol35_name 的漏率检查,采用了逻辑 df[col34_name] > 5 | df[col34_name] <= 0,确保漏率大于 5 或小于等于 0 时才添加错误。
  3. 对其他设备漏率检查:

    • 对 "1#VIM" 和 "3#VIM" 的漏率检查,分别在漏率大于 25 或大于 50 时标记为错误。

效果:

  • 现在,只有当漏率值大于 5 或小于等于 0 时,才会将该记录加入错误数据列表。
  • 设备为 "2#VIM" 或 "4#VIM" 时,漏率检查会应用到 col34_name,设备为 "1#VIM" 和 "3#VIM" 时,漏率检查会应用到 col35_name

这种逻辑保证了排除 col34_name == 0 的情况,并且针对不同设备的漏率应用了不同的检查标准。

Evaluating optimization for data display

The user wants to optimize the check_data function so that only rows that fail error conditions are shown, instead of displaying all data. It seems that the current logic might be showing unnecessary rows because error conditions aren't applied separately. Some data might pass one condition, but rows that do not fail any conditions might mistakenly appear with a false error condition. I’ll need to re-read the code to confirm this issue and figure out the solution.

Troubleshooting error display issue

The user's current setup checks several error conditions for different columns, then filters the data based on these conditions. The user likely wants to show only rows with errors, but the code might display duplicates because it's checking conditions separately. If a row satisfies more than one condition, it could appear more than once. It seems the issue lies in how the conditions are applied and filtered, so I'll need to refine the error filtering logic to ensure only error-specific rows are shown.

Analyzing error conditions

The user's issue seems to be that non-error rows are showing up, likely due to some condition not filtering correctly. It looks like the error condition for col329_name might be wrong — it mistakenly uses df[col36_name] > 5 instead of df[col329_name] > 5. Fixing this should help. There could also be issues with how conditions are combined and grouped, especially for leak rate and equipment checks, which might cause rows that don't meet all conditions to still appear. I'll optimize the code by combining conditions properly and handling errors more efficiently.

Optimizing error condition checks

The user wants to exclude rows where certain columns are zero, like col34_name, interpreting their request to avoid showing rows related to zero values. To refine this, I’ll make sure the error condition checks are more precise — for example, excluding zero values in leak rate checks and modifying checks like col329_name to exclude zeros. Additionally, I'll optimize the iteration by grouping conditions carefully to avoid duplicates. I'll then reformat the code for clearer and more efficient error handling, ensuring only valid errors are displayed.

下面给出优化后的代码与说明。主要改进思路包括:

  1. 明确各个错误条件的判断逻辑

    • 使用单独的条件语句构建错误条件列表,每条错误条件均采用向量化的布尔运算。
    • 对于漏率的判断,根据设备不同,设置单一阈值比较,例如对于“2#VIM”或“4#VIM”,仅当漏率大于 5 时才视为错误(从而排除值为 0 的情况);对于“1#VIM”或“3#VIM”,分别设定漏率错误的阈值(同样不将值为 0 判为错误)。
  2. 避免条件组合时的逻辑优先级混乱

    • 原代码中使用 or 组合时未使用括号,导致逻辑错误。优化后,直接对各个条件分别判断,再统一添加到错误条件列表中。
  3. 检查并更正了精炼期预真空的判断条件

    • 原条件中使用了 df[col36_name] > 5(应检查的列为 col329_name),同时如果不希望将值为 0 的情况当作错误,则只检查大于阈值的情况。

下面是优化后的完整代码:


python
# functions/check_data.py import pandas as pd import os def check_data(file_path, start_date, equipment): try: # 读取 Excel,并获取所有列名 df = pd.read_excel(file_path, header=0) # 对第12列(开始日期,索引 11)和第6列(设备,索引 5)进行筛选 start_date_col = df.columns[11] equipment_col = df.columns[5] # 将 Excel 中的开始日期转换为日期类型,并解析用户传入的开始日期 df[start_date_col] = pd.to_datetime(df[start_date_col], errors='coerce') start_date_parsed = pd.to_datetime(start_date, errors='coerce') if pd.isna(start_date_parsed): return {"error": "无效的开始日期"} # 筛选:仅保留开始日期大于等于所选日期且设备匹配的行 df = df.loc[(df[start_date_col] >= start_date_parsed) & (df[equipment_col] == equipment)] # 如果筛选结果为空,则返回空记录 if df.empty: return { "header": [], "rows": [] } # 获取所需的列名 col1_name = df.columns[0] # 炉号 col2_name = df.columns[1] # 铸锭总重量 col10_name = df.columns[9] # 熔炼总时长 col18_name = df.columns[17] # 流槽转移时间 col20_name = df.columns[19] # 浇注开始时间 col21_name = df.columns[20] # 浇注结束时间 col34_name = df.columns[33] # 2#VIM和4#VIM漏率 col35_name = df.columns[34] # 1#VIM和3#VIM漏率 col36_name = df.columns[35] # 精炼前真空度 col329_name = df.columns[328] # 精炼期预真空 # 构建错误条件列表,每条条件的格式为 (错误列名, 布尔型条件 mask) error_conditions = [] # 常规错误: error_conditions.append((col2_name, df[col2_name] <= 0)) # 错误1:铸锭总重量 <= 0 error_conditions.append((col10_name, df[col10_name] <= 0)) # 错误2:熔炼总时长 <= 0 error_conditions.append((col18_name, df[col18_name] >= df[col20_name])) # 错误3:流槽转移时间 >= 浇注开始时间 error_conditions.append((col20_name, df[col20_name] >= df[col21_name])) # 错误4:浇注开始时间 >= 浇注结束时间 error_conditions.append((col36_name, (df[col36_name] > 10) | (df[col36_name] == 0))) # 错误5:精炼前真空度 > 10 或等于 0 # 精炼期预真空,只检查大于阈值(不显示值为 0 的情况) error_conditions.append((col329_name, df[col329_name] > 5)) # 错误6:精炼期预真空 > 5 # 设备特定的漏率错误判断: if equipment in ["2#VIM", "4#VIM"]: # 仅当漏率超过 5 时才记录错误,排除漏率为 0 的情况 error_conditions.append((col34_name, df[col34_name] > 5)) elif equipment == "1#VIM": error_conditions.append((col35_name, df[col35_name] > 25)) elif equipment == "3#VIM": error_conditions.append((col35_name, df[col35_name] > 50)) # 遍历所有错误条件,将符合条件的记录收集到 error_rows 中 error_rows = [] for error_col, condition in error_conditions: # 仅对满足条件的行进行迭代 for _, row in df.loc[condition].iterrows(): error_rows.append([row[col1_name], error_col, row[error_col]]) return { "header": [col1_name, "错误列", "错误数据"], "rows": error_rows } except Exception as e: return {"error": str(e)} finally: # 删除临时文件,防止文件堆积 if os.path.exists(file_path): os.remove(file_path)

说明

  • 错误条件构建
    每条错误条件均单独构造并加入 error_conditions 列表。在设备特定部分,使用了 if equipment in ["2#VIM", "4#VIM"]: 分支,仅对漏率大于 5 的情况添加错误条件,这样不会误将漏率为 0 的记录加入错误列表。同理,对“1#VIM”与“3#VIM”的漏率也只判断大于各自阈值的情况。

  • 条件逻辑规范
    通过括号明确各个布尔条件的组合,避免了原先因逻辑运算顺序不明确而导致错误判断的问题。

  • 遍历并收集错误记录
    使用 df.loc[condition] 遍历每个错误条件,收集对应错误记录,保证最终返回的数据仅包含满足错误判断的记录。

这样调整后,只有真正满足错误条件的行会被加入最终的错误结果中,不会将“其余”的正常数据展示出来。
