Write a code generator using python

1. Project source

The company needs to call other database data in the form field, and needs to use the ajax script interface to call

In this regard, each time the corresponding data is modified and checked one by one, the program is error-prone, troublesome, and time-consuming

Therefore, I wrote a program for this kind of repetitive work: "write code with code"

2. Project introduction

In the simplest way, splice and modify the corresponding code, use pandas to read the excel table data and generate it in the variable corresponding to the code, use tkinter as the gui interface, and finally package the function into an exe file for others to use

3. Operation effect

 

Write the data into excel, and run the program to call the file to generate as follows:

Undoubtedly, for huge multi-field correspondence, it can be quickly generated to improve efficiency

4. Core code introduction

1. Use pandas to locate the row and column coordinates of the table

Make the corresponding list the variable that needs to be used, as follows, mainly perform a for loop to read the corresponding data according to the number of columns in the excel and save it in the corresponding list variable

# 选择文件安放的位置
def get_file():
    # filedialog.askopenfilenames可以返回多个文件名
    data_1 = tkinter.filedialog.askopenfilename(title="选择文件")
    data = data_1
    print('路径为:', data)
    x = pd.read_excel(data)
    for o in range(0, len(x.columns)):
        field_sync_l.append(x.loc[0][o])

    # print(x.loc[0][1])
    print(field_sync_l)
    for o in range(0, len(x.columns)):
        field_sync_r.append(x.loc[1][o])
    print(field_sync_r)
    entry.delete(0, END)
    entry.insert(0, data)

2. Define the corresponding variable and the corresponding format

The copy here mainly uses f'' to assign the corresponding string. Among them, the symbol corresponding to \ is easy to be treated as a newline or escape character by the compiler. Therefore, when writing, we need to use \\ instead \.

The d variable in this piece of code needs to be thought about, because considering each data not only needs to convert case, but also use ''.join(map(str,x[i])) to convert the list into a string, and assign it to In the corresponding array d[i]

Therefore, when the i variable increases, the subscript of d also increases, otherwise field_sync_l[i] will be executed multiple times in the map

In order to ensure that the subscript index range is not exceeded, it is necessary to add [' '], [' '], [' '] to d in a loop, which is actually a type of tuple, not [' ',' ',' '], they are very different, the first one is a different situation corresponding to an independent subscript each time, and the second is just an array traversal subscript

       d[i] = f"""    this.$set(this.formData, "{TABLE_L}-{''.join(map(str, field_sync_l[i])).upper()}", json.{''.join(map(str, field_sync_r[i])).lower()});"""

def in_data():
    fun = 'GetDataTableBySql?'
    API = '/RunVser/'
    TABLE_L = field_sync_l[0]  # 使用表
    TABLE_R = field_sync_r[0]  # 来源表
    field_invoke = 'xingming'
    field_invoke = field_invoke.upper()
    field_source = 'xingming'
    # field_sync_l = ['xingming'], ['gonghao']
    # field_sync_r = ['Xingming'], ['gonghao']
    sql = f"select top 1 * from {TABLE_R} where {field_source}=\\''"
    a = """this.ajax.post('{API}{fun}sql={sql}+this.formData["{TABLE_L}-{field_invoke}"]""" \
        .format(API=API, fun=fun, sql=sql, TABLE_L=TABLE_L, field_invoke=field_invoke, TABLE_R=TABLE_R)
    b = """+'\\'').then((data) => { """
    c = """  if (data.success) {
        console.log(data.data);
        let json = data.data;"""
    d = ['']
    for i in range(0, len(field_sync_l) - 1):
        d.append('')
        # print(d)
    for i in range(1, len(field_sync_l) - 1):
        d[
            i] = f"""    this.$set(this.formData, "{TABLE_L}-{''.join(map(str, field_sync_l[i])).upper()}", json.{''.join(map(str, field_sync_r[i])).lower()});"""
        x = '\n'.join(map(str, d))
    e = """  } else {
        alert(data.msg);
        }
    }).catch((e) => {
        console.log(e);
    });"""
    m = f'{a}\n{b}\n{c}\n{x}\n{e}'
    code_ares.insert(INSERT, m)
    print(m)

Finally, use m to splice each traversal together to generate code

Six. Package exe format

Use
the Pyinstaller -F -w xxx.py command to package the file into an exe file that does not use the console

After being packaged into exe, it can be sent out, and it can be executed without compiling environment

 7. The transmission effect of ajax on the page

Summary: Leave the repetitive things to the code
