在Django中使用generic.FormView时如何在模板中调用表单？

Question

This is my form class: from django import forms

from .models import Category


class AddResource(forms.Form):

    CATEGORY_CHOICES = [cat.title for cat in Category.objects.all()]

    ResourceTitle = forms.CharField()
    Description = forms.Textarea()
    Link = forms.URLField()
    Categories = forms.MultipleChoiceField(choices=CATEGORY_CHOICES)

This is my view for the form URL:

from django.shortcuts import render
from django.views.generic import View, TemplateView, FormView

from .models import *
from .forms import AddResource


class AddResourceView(FormView):

    template_name = 'addRes.html'
    form_class = AddResource
    success_url = '/'

    def get_form(self, form_class):
        return form_class()

    def form_valid(self, form):
        print form
        return super(AddResourceView, self).form_valid(form)

The trouble that I'm having is calling this inside templates. How do I call the form that I assigned inside of django-templates?

Answer 1

The FormView supplies a context variable called form that holds your actual form object, so you can use:

{{ form.as_table }}

Or any of the other rendering options that form supplies. See: https://docs.djangoproject.com/en/dev/topics/forms/#displaying-a-form-using-a-template

Answer 2

I found the answer. Its how you include choices in django forms. So CATEGORY_CHOICES has to be a list of tuples, which it was not in this case.

Thus, this simple change made it work:

CATEGORY_CHOICES = [('', cat.title)
                    for cat in Category.objects.all()]
