    copied!<p>I'm trying to create a dialog which uses jquery's .load() function to slurp in a rendered django form. The .load function is passed the pk of the "alert" object. Also available in the class functions are things like <code>self.request.user</code> so I can pre-fill those fields, shown below in the Message model (models.py):</p> <pre class="lang-python prettyprint-override"><code>class Message(models.Model): user = models.ForeignKey(User) alert = models.ForeignKey(Alert) date = models.DateTimeField() message = models.TextField() </code></pre> <p>Subclassing django's CreateView makes it pretty easy to generate a context with an instance of the ModelForm (views.py):</p> <pre class="lang-python prettyprint-override"><code>class MessageDialogView(CreateView): """ show html form fragment """ model = Message template_name = "message.html" def get_initial(self): super(MessageDialogView, self).get_initial() alert = Alert.objects.get(pk=self.request.POST.get("alert_id")) user = self.request.user self.initial = {"alert":alert.id, "user":user.id, "message":"test"} return self.initial def post(self, request, *args, **kwargs): super(MessageDialogView, self).post(request, *args, **kwargs) form_class = self.get_form_class() form = self.get_form(form_class) context = self.get_context_data(form=form) return self.render_to_response(context) </code></pre> <p>The problem here is that <code>self.initial</code> does not get rendered with the form. I have insured that the form is indeed calling <code>get_initial</code> and the form instance has the proper initial data in <code>post</code>, but when the form is rendered in the template <code>message.html</code> it doesn't grab any of the initial data like I would expect. Is there a special trick to get this to work? I've scoured the docs (seems to be lacking examples on generic based class views) and source but I can't see what I'm missing.</p>
 

Querying!
