Views.py processing the form data - html

Question

My form.html
{{ form_field(task_form['execution_time']) }}
<input type="text" name="admin_time">
views.py
class CreateTaskView(LoginRequiredMixin, MyStaffUserRequiredMixin, generic.CreateView):
model = Task
form_class = TaskForm
template_name = 'tasks/form.html'
def get_context_data(self, *args, **kwargs):
ctx = super(CreateTaskView, self).get_context_data(*args, **kwargs)
ctx['task_form'] = ctx.get('form')
ctx['action'] = 'Add'
ctx['cancel_url'] = reverse('tasks.list')
return ctx
def form_valid(self, form):
form.save(self.request.user)
messages.success(self.request, _('Your task has been created.'))
return redirect('tasks.list')_url'] = reverse('tasks.list')
return ctx
When processing the form if admin_time has a value, then execution_time should be equal to admin_time.
How can I bring that about?
I want something like this- but it throws eror
def get_context_data(self, *args, **kwargs):
ctx = super(CreateTaskView, self).get_context_data(*args, **kwargs)
ctx['task_form'] = ctx.get('form')
if self.admin_time.is_valid():
task.execution_time=self.admin_time
else:
ctx['action'] = 'Add'
ctx['cancel_url'] = reverse('tasks.list')
return ctx

CreateView.get_context_data used to send additional context to your template (or override exist one) and it yields only when you have to render empty values request.GET
You can receive data on request.POST, so it yields methods in order (main of them) dispatch -> post -> form_valid or form_invalid -> redirect to success url. You can see there is no get_context_data so remove that weird code from get_context_data:
if self.admin_time.is_valid():
task.execution_time=self.admin_time
else:
I can see you override form_valid so if it runs - form already is valid and you can get "cleaned data" from it if you want perform some additional validation, put following code before form.save():
admin_time = form.cleaned_data['admin_time']
# check if it is not empty
if admin_time:
self.execution_time = admin_time
And you should not do this return ctx in your form_valid, because it never reach here after first return.
I also recommend you look at CreateView class implementation https://docs.djangoproject.com/en/1.7/ref/class-based-views/generic-editing/#createview and Django tutorials and docs if you want understand what you are doing https://docs.djangoproject.com/en/1.7/intro/tutorial01/ there ~ 6 tutorials, read and try it all and http://www.checkio.org/ for learning python. Because here we mainly don't loyal for such questions.
