Provide extra context to all views

阅读更多关于 Provide extra context to all views

I'm putting together a project management website for my team using django. My base template includes a sidebar menu which contains a list of all projects and users, linking to a DetailView for that user or project, respectively. My problem is that I need to provide the User and Project models to every view so that I can render that sidebar. I know how to add extra context ; the problem is that I feel like I'm violating DRY by modifying the context at each level. Is it possible to simply redefine the base TemplateClass so that all child classes— ListView , DetailView , etc.—contain the

Extending Django's Generic Views

阅读更多关于 Extending Django's Generic Views

I'm writing my first app in Django, and I have a problem with the create_object Generic View; In my urls.py , I have: (r'^new$', CreateView.as_view()), The problem is that when the user submits the "new" form, I need to manipulate the data that will be saved to the database (I actually need to add the user_id foreign key); without Generic Views I used to write: form = ClientForm(request.POST) if form.is_valid(): data = form.save(commit=False) data.user = request.user data.save() form.save_m2m() in my view (notice data.user=request.user ). I've searched Django docs but I can't find a way to do

Django formset set current user

阅读更多关于 Django formset set current user

问题 Related to this question, but expanding on it - How would I use this technique in a formset? I'd like to use the current logged in user in a form, but I'm using the form in a formset. The referenced solution for a single form is to pass request.user to the form and process in init. How do I add to the kwargs for each form in the formset? Example in my code: in forms.py class NewStudentForm (forms.Form): username = forms.RegexField(label=_("Username"), max_length=30, regex=r'^\w+$', help_text

I try to test a view, I receive a json request from the IPad, the format is: req = {"custom_decks": [ { "deck_name": "deck_test", "updates_last_applied": "1406217357", "created_date": 1406217380, "slide_section_ids": [ 1 ], "deck_id": 1 } ], "custom_decks_to_delete": [] } I checked this in jsonlint and it passed. I post the req via: response = self.client.post('/library/api/6.0/user/'+ uuid + '/store_custom_dec/',content_type='application/json', data=req) The view return "creation_success": false The problem is the post method in view doesn't find the key custom_decks.

Django HttpResponseRedirect

阅读更多关于 Django HttpResponseRedirect

I have created a basic contact form, and when the user submits information, it should redirect to the "Thank You" page. views.py : def contact(request): # if no errors... return HttpResponseRedirect('/thanks/') urls.py : (r'^contact/$', contact), (r'^contact/thanks/$', contact_thanks), Both pages work at the hard-coded URL. However, when I submit the form on /contact/ it redirects to /contact (no ending slash), which is a nonexistent page (either a 404 or an error page telling me I need a slash). What is the reason it not correctly redirecting, and how can I fix this? UPDATE: the return

I am using django modelformset_factory in one of my view. I am using javascript for adding new forms to the formset in Template. Everything is working fine but my problem is that when i try to create a new object using modelformset_factory it shows me all the objects as forms which i previously created.

Like I have defined extra = 0 while initializing the modelformset_factory and from template I added 5 forms to formset and submitted those. Next time when I will re render the
