python - Django 表单不从 HomeForm 类呈现 HTML

问题描述

出于某种原因，我无法让我的 Django 表单呈现。我不确定我错过了什么。

我正在尝试class HomeForm(forms.Form)在页面上呈现，但myaccount/change.html没有成功。

我是 Django 新手，所以我可能在某处遗漏了一个小细节，但我认为我从 djago 文档中得到了所有内容。

如果有人可以帮助我，将不胜感激。谢谢！

用户/forms.py

from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from django import forms
from .models import CustomUser

class HomeForm(forms.Form):
    post = forms.CharField()
    your_name = forms.CharField(label='Your name', max_length=100)


class CustomUserCreationForm(UserCreationForm):
#    job_title = forms.IntegerField(label='2 + 2', label_suffix=' =')
#    yes = forms.IntegerField(required=True)
    tos_check = forms.BooleanField(required=True, label='I have read and agree to the Terms of Service.')
    age_check = forms.BooleanField(required=True, label='I am 21 years of age or older.')

    class Meta(UserCreationForm.Meta):
        model = CustomUser
        fields = ('username', 'email')
        help_texts = {
            'username': '',
            'email': '',
#            'password1': 'None',
#            'password2': 'Test'
        }

class CustomUserChangeForm(UserChangeForm):

    tos_checktwo = forms.BooleanField(required=True, label='I have read and agree to the Terms of Service.')


    class Meta(UserChangeForm.Meta):
        model = CustomUser
        fields = ('username', 'email', 'tos_checktwo')

#    class Meta:
#        model = CustomUser

解决方案

先生，我在共享的代码中没有发现任何问题。但这里有两个提示：

  1. 检查 base.html 中是否包含块内容。
  2. 在视图中的 return 之前添加print(form)以查看您得到的内容（打印结果将在终端上而不是浏览器上）

编辑： 您应该添加一个调用视图的 url：在 url 添加此行：

path('testform/', view.get_name, name ='get_name')

然后在你的浏览器上，测试 url127.0.0.1:8080/testform/
