如何在django选择字段中添加列表值？

我的代码是

from django import forms
import os
drives_a = [chr(x) + "," for x in range(65, 90) if os.path.exists(chr(x) + ':')]

class contactForm(forms.Form):
    drives = forms.CharField(label='Drive Name', widget=forms.Select(choices=drives_a))

Answer 1

选择通常是布局的

choices = (
    (key1, 'opt1'),
    (key2, 'opt2'),
)

确保工作然后修改你的drive_a语句来创建它

Answer 2

How to add name in drive value in label name

来自django import forms import os，来自django.forms.models的字符串导入ModelForm

drives_a = [chr（x）+'：'for x in range（65,90）if os.path.exists（chr（x）+'：'）]

drives_b = (chr(x)+':' for x in range(65, 90) if os.path.exists(chr(x) + ':'))

CHOICES_DRIVE = [（“Drive”，drives_a），

]

class contactForm（forms.Form）：drive = forms.CharField（widget = forms.RadioSelect（choices = CHOICES_DRIVE））
