forms.py
from django import forms from django.forms import fields from django.forms import widgets from django.forms.models import ModelChoiceField from app01 import models class UserInfoForm(forms.Form): user = fields.CharField( required=True, widget=widgets.Textarea(attrs={‘class‘:‘c1‘}) ) pwd = fields.CharField( max_length=12, widget=widgets.PasswordInput(attrs={‘class‘:‘c1‘}) ) user_type = fields.ChoiceField( # choices=[(1,‘普通用户‘),(2,‘超级用户‘)], choices = [], # widget = widgets.Select ) user_type2 = fields.CharField(widget=widgets.Select(choices=[])) #方式二,models.py中需要加上def __str__(self):return self.name

views.py
from django.shortcuts import render from app01.forms import UserInfoForm from app01 import models # Create your views here. def index(request): obj = UserInfoForm() # obj.fields[‘user_type‘].choices = models.UserType.objects.values_list(‘id‘,‘name‘) #类里面的静态字段，必须重新去数据库取值赋值,或者在forms.py中构造函数中取值 return render(request,‘index.html‘,{‘obj‘:obj})
index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <p> {{ obj.user }} </p> <p> {{ obj.pwd }} </p> <p> {{ obj.user_type }} {{ obj.user_type2 }} </p> </body> </html>
