Question

我使用TemplateView编写了一个CBV，将两个表单放在模板上。但是只有提交按钮显示减去字段。

multiple_form.html

<form action="" method="post">
    {% csrf_token %}
    {{ context.form1.as_p }}
    <input type="submit">
</form>

<form action="" method="post">
    {% csrf_token %}
    {{ context.form2.as_p }}
    <input type="submit">
</form>

forms.py

from django import forms
from django.forms import ModelForm


class Form1(forms.ModelForm):
    username        = forms.CharField(label=(u'User Name1'))
    email           = forms.EmailField(label=(u'Email Address1'))

class Form2(forms.ModelForm):
    username        = forms.CharField(label=(u'User Name2'))
    email           = forms.EmailField(label=(u'Email Address2'))

views.py

from django.core.urlresolvers import reverse
from django.views.generic import TemplateView

from article.forms import Form1, Form2

class MultipleFormView(TemplateView):
    template_name = 'blog/multiple_form.html'

    def get_context_data(self, **kwargs):
        context = super(MultipleFormView, self).get_context_data(**kwargs)
        context['form1'] = Form1
        context['form2'] = Form2
        return context

        success_url = '/'

Answer 1

尝试删除多余的＆＃39;上下文＆＃39;在您的HTML中，{{context.form1}}会错误地链接到不存在的context['context']['form1']。

<form action="" method="post">
    {% csrf_token %}
    {{ form1.as_p }}
    <input type="submit">
</form>

<form action="" method="post">
    {% csrf_token %}
    {{ form2.as_p }}
    <input type="submit">
</form>

Answer 2

删除模板中无用的context，只需form1.as_p即可。

<form action="" method="post">
    {% csrf_token %}
    {{ form1.as_p }}
    <input type="submit">
</form>

<form action="" method="post">
    {% csrf_token %}
    {{ form2.as_p }}
    <input type="submit">
</form>

您需要实例化表单对象，而不是在您的上下文中传递该类。在这里，你传递的是一个类，Django将无法使用它。

class MultipleFormView(TemplateView):
    template_name = 'blog/multiple_form.html'

    def get_context_data(self, **kwargs):
        context = super(MultipleFormView, self).get_context_data(**kwargs)
        context['form1'] = Form1()  # <----
        context['form2'] = Form2()  # note the parenthesis here
        return context

        success_url = '/'

为什么我的CBV表格没有字段？
