How to Create a UpdateForm with TemplateView? - django

Question

I need to create a UpdateForm with a TemplateView. Why with TemplateView? Because, I has a attribute what is geo_location, and I'm using LeafLet maps, and LeafLet maps doesn't work with generic.UpdateView or others the same type.
Here my views from Update:
class UpdateStore(LoginRequiredMixin, TemplateView):
template_name = 'store_form'
success_url = reverse_lazy('register:store_list')
def post(self, request, *args, **kwargs):
store_id = kwargs['store']
store = get_object_or_404(Store, pk=store_id)
form = StoreForm(request.POST, on_edit=True)
if form.is_valid():
form.save()
return redirect(reverse('register:store_list'))
else:
context = self.get_context_data()
context['data_form'] = form
return render(request, self.template_name, context)
return self.get(request)
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
store_id = self.kwargs['store']
store = get_object_or_404(Store, pk=store_id)
data = {
'name': store.name,
'description': store.description,
'address': store.address,
'geo_loc': store.geo_loc,
'opened': store.opened
}
context['editing'] = True
context['data_form'] = StoreForm(initial=data, on_edit=True)
context['store'] = store
return context
Here is my template code:
{% extends 'base.html' %}
{% load bootstrap3 %}
{% load leaflet_tags %}
{% block extra_css %}
{% leaflet_css plugins="forms" %}
{% endblock %}
{% block body %}
<h1> Update Store </h1>
<form method="POST">
{% csrf_token %}
{{ form }}
{% buttons %}
<button type="submit">
{% bootstrap_icon "star" %} Save
</button>
{% endbuttons %}
</form>
{% endblock %}
{% block extra_js %}
{% leaflet_js plugins="forms" %}
{% endblock %}
I trying this, but in my template, the Forms doesn't load, and my template are blanked :(. Someone knows why? I need another method for get anything else?
Thanks.

The problem with your code is that you place the form in the data_form key of the context:
context['data_form'] = StoreForm(initial=data, on_edit=True)
and then on the template you try to use it with {{form}} instead of {{data_form}}. After that the form should be rendered.
