Django One View, Multiple Forms


Example

Here is a quick example of using multiple forms in one Django view.

from django.contrib import messages
from django.views.generic import TemplateView

from .forms import AddPostForm, AddCommentForm
from .models import Comment

class AddCommentView(TemplateView):

    post_form_class = AddPostForm
    comment_form_class = AddCommentForm
    template_name = 'blog/post.html'

    def post(self, request):
        post_data = request.POST or None
        post_form = self.post_form_class(post_data, prefix='post')
        comment_form = self.comment_form_class(post_data, prefix='comment')

        context = self.get_context_data(post_form=post_form,
                                        comment_form=comment_form)

        if post_form.is_valid():
            self.form_save(post_form)
        if comment_form.is_valid():
            self.form_save(comment_form)

        return self.render_to_response(context)     

    def form_save(self, form):
        obj = form.save()
        messages.success(self.request, "{} saved successfully".format(obj))
        return obj

    def get(self, request, *args, **kwargs):
        return self.post(request, *args, **kwargs)
