django-forms - 需要使用 Django 表单的列表复选框

Question

forms.py

from django import forms
from .models import VendorApplication, VendorAppWorkFlow
import MySQLdb as mdb
from django.forms.fields import DateField, ChoiceField, MultipleChoiceField
from django.forms.widgets import RadioSelect, CheckboxSelectMultiple
from django.forms.extras.widgets import SelectDateWidget


con = mdb.connect('', '', '', '');
cursor1 = con.cursor()
cursor1.execute("select * from vendorapp_sharetable;")
columns = cursor1.description
num_fields = len(cursor1.description)
field_names = [i[0] for i in cursor1.description]

class CheckForm(forms.Form):
    for index in range(num_fields):
       field_names[index] = forms.BooleanField(required=False, label=field_names[index])

我想在forms.py没有选择的情况下将 field_names 值添加到复选框列表中，或者我如何在选择中迭代它们以拥有checkboxMultiselect widget. 由于field_names我的应用程序中的数量不同，因此难以将它们添加到选项中并使用复选框小部件。

Answer 1

就像是：

field_names = [i[0] for i in cursor1.description]

choices = [(x, y) for (x, y) in enumerate (field_names)]

class CheckForm (forms.Form):
    fields = forms.CheckboxMultiSelect (choices = choices, required = False)
