Not able to redirect to another page after clicking on submit button django
So, I have implemented a bit of post, get and update in the following code. After submitting the values into the database. The return redirect is not changing the page to UserProfile.html which in urls.py is user_profile Code urls.py path('user_profile', views.user_profile, name="user_profile"), views.py def edit_profile(request): try: # checking if the user exist in UserProfile through the logged in email id user_data = UserProfile.objects.get(emailID = request.user.email) # if request.method == "POST" and request.FILES: if request.POST.get('action') == 'post': name = UserProfile.objects.all() response_data = {} # user_img = request.FILES['user_img'] name = request.user.username emailID = request.user.email phone = request.POST.get('phone') college_name = request.POST.get('college_name') branch = request.POST.get('branch') # response_data['user_img'] = user_img response_data['name'] = name response_data['emailID'] = emailID response_data['phone'] = phone response_data['college_name'] = college_name response_data['branch'] = branch # updating the current logged in user values user_data = UserProfile.objects.get(emailID = request.user.email) if(user_data.emailID == request.user.email): UserProfile.objects.filter(emailID = request.user.email).update( name = name, emailID = emailID, phone = phone, college_name = college_name, branch = branch ) return redirect('/user_profile') except UserProfile.DoesNotExist: name = UserProfile.objects.all() response_data = {} # creating new user if request.POST.get('action') == 'post': # user_img = request.FILES['user_img'] name = request.user.username emailID = request.user.email phone = request.POST.get('phone') college_name = request.POST.get('college_name') branch = request.POST.get('branch') # response_data['user_img'] = user_img response_data['name'] = name response_data['emailID'] … -
How to access the instance of the ClusterableModel parent object from a child orderable before the orderable has been saved?
When creating orderables as children of a clusterablemodel, is there any way to access properties of the parent before that parent instance has been saved? The ParentalKey is None until the orderable instance has been saved. Maybe it's possible to pass variables to the orderable when the orderable instance is created? I want to filter the choices offered on the orderable based on the parent properties but can't find any way to do this, only one-filter-for-all. Abbreviated code from a Wagtail test project: @register_snippet class ParentSnippet(TranslatableMixin, ClusterableModel): code = models.CharField(blank=False, null=True, max_length=10) title = models.CharField(blank=False, null=True, max_length=50) .... class ChoiceListIterator(object): def __iter__(self): dropdown_list = list(ChoiceListClass.objects.values_list('code','title')) return dropdown_list.__iter__() class ChildOrderable p_key= ParentalKey( "ParentSnippet", related_name="child_items", ) choice_list=ChoiceListIterator() submenu_selector=Select() submenu_selector.choices = choice_list dropdown_test = models.CharField( blank=False, null=True, max_length=10, choices=choice_list ) panels = [ FieldPanel("dropdown_test"), ] This is fine for showing everything from the ChoiceListClass (just something to return items for this example), the dropdownlist is populated dynamically. Ideally, I want to be able to pass either the parent snippet or properties based on the parent snippet into the ChoiceListIterator constructor and then use this to filter the dropdown_list. eg choice_list=ChoiceListIterator(parent_snippet_instance) But how to access the instance of the parent object creating the orderable … -

Django page not found (404) in my core/urls.py file. Only works when the urls are rearranged
I am relatively new to Django. I've set up my URLs in my core/urls.py file this way and I do get a 404 error when I opened localhost:8000/posts/ on the browser. Code is shown here urlpatterns = [ path('', views.IndexView.as_view(), name='index'), path('<slug:slug>/', views.SingleView.as_view(), name='single'), path('posts/', views.PostsView.as_view(), name='posts'), ] However, everything works fine when I reverse the slug and posts/ to make the posts come before the slug. Like this: urlpatterns = [ path('', views.IndexView.as_view(), name='index'), path('posts/', views.PostsView.as_view(), name='posts'), path('<slug:slug>/', views.SingleView.as_view(), name='single'), ] Please help me figure it out. -
How do I obtain references to other data being submitted in the Django admin?
I have a multiple-choice test app in Django 3.0. It has two models, Question and Choices # models.py class Questions(models.Model): question = models.CharField( help_text='Text of question' ) class Choices(models.Model): def clean(self): choicesSet = Choices.objects.filter(q=self.q) if ( choicesSet.count() != 4 ): raise ValidationError( "Four Choices must be provided." ) q = models.ForeignKey( Questions, on_delete=models.CASCADE ) option = models.CharField( help_text='Text of choice' ) The Admin page for Questions includes inputs for four Choices. When Choices are input, I want to make sure that a complete set of four are input at the same time. I attempted to do this with the Choices.clean() function shown, but it fails. When I enter four choices and attempt to save, each Choice returns the error "Four Choices must be provided". I think what's happening is that since the record is not successfully saved, choicesSet = Choices.objects.filter(q=self.q) returns zero because no Choices are foreign-keyed to the Question q=self.q yet. How can I obtain references to the other three Choices in the clean() function of one Choice during validation? I've read the documentation for Model validation and Form and field validation, but it's more confusing than helpful. -

Django get field from m2m and foreign key
I am adding functionality to my django application to add models(Lot) linked to another(Job) with an M2M field.

Making complex query with django models
I created a view in my database model with 6 joins and 10 columns, and at the moment it shows around 86.000 rows. I try to query all the rows by objects.all() and then filter according to user interaction (form data sent by POST and then choosing appropriate .filter(*args) querying) After that I tried to get the length of the queryset by using count() since this method doesnt evaluate the query. But since views don't have indexes on the columns, the count() method takes to long. I searched for the solution of materializing the view but that isn't possible in mysql. Then I searched for a solution that might be able to replace the initial .all() by just using the 6 joins and filtering arguments in django rather than creating a view, so the indexes would still be available. But I couldn't find a solution to that problem. Or maybe combining every row from the view with another table so I can use the index of the other table for faster querying?: SELECT * FROM View LEFT JOIN Table ON (View.id = Table.id) I appreciate every answer -
