Django use StrIndex to get the last instance of a character for an annotation
I have a model with a key that's value is a file path, ie /src/code/foo. I need the file name so I want to get the sub string of foo for my annotation value. The logical way I was aiming to go about it was to get the index of the last / character. I was trying to do this via StrIndex & Substr but StrIndex only gives me the first index. Is there a way I can get the last index instead? MyModel.objects.all().annotate( # this would give me `src/code/foo` but I want just `foo` name=Cast(Substr("file_path", StrIndex("file_path", V("/"))), TextField()) ) -
How do I use formset data as initial data in my forms? Error is ' The inline value did not match the parent instance.'
I have a formset that I use to collect some data. I also want to use that same data as the initial data to a different formset. In order to do this, I have a form that looks like... def __init__(self, *args, **kwargs,): dropdown = kwargs.pop('dropdown', None) super(TeamFormSet, self).__init__(*args, **kwargs) self.queryset = Player.objects.filter(team_pk=dropdown) After a bunch of searching and massaging....I've gotten this to work exactly how I want. The challenge I'm having now is when I'm loading this form, I am getting an error that says The inline value did not match the parent instance. I've done some research on the querysets and formsets and I understand django knows how this data was created originally, but I am trying to essentially use the values as a starting point for this form. I have seen that get_initial might be available for formsets. Is there some other way I should be getting the data rather than the way I am going about it above? The data is dynamic, and since I've already captured it in another part of the system, I can't see why I shouldn't be able to use the values at a minimum as a starting point for a different … -
Django: best way to produce a 70+ page form
I'm trying to create a quiz web app on Django, where each quiz has 75 multi-choice questions, and each question is displayed on its own page (see screenshot for an example of what one question page would look like). The user should be able to navigate backwards and forwards between each 'page' of questions, so answers for each question must persist once they have been entered. Each question will have four radio button answer choices. At the end of the quiz, the user will submit answers and they will be stored in a database. What is the best way to go about implementing this in Django? I have done some research and found two options, although I'm not sure which is best in terms of efficiency since each quiz is going to be quite large and will require a lot of individual pages. form wizard: https://django-formtools.readthedocs.io/en/latest/wizard.html JS steps: https://www.w3schools.com/howto/howto_js_form_steps.asp? Open to other methods, advice greatly appreciated. -
null value in column "x" violates not-null constraint
I making a feature where one user can follow another. I had this working momentarily but then it broke again (I got some assistance from a mentor).

Django query for model with a single DateField used for tracking state changes
I have searched all over StackOverflow, but can't seem to find anything like this. Assuming we have the following model (purposely simplified): class X(models.Model): related_object = models.ForeignKey(Y) start_date = models.DateField(unique=True) is_rented = models.BooleanField() Where model X is tracking state changes of an instance of model Y. It could be tracking something like the state of cars at a car rental agency that may be rented out. A new instance of the model is created each time the state of each car changes. The resulting objects might look something like this: {"id" : 1, "related_object" : 2, "start_date" : "2021-03-03", "is_rented" : False}, {"id" : 2, "related_object" : 2, "start_date" : "2021-03-06", "is_rented" : False}, {"id" : 3, "related_object" : 2, "start_date" : "2021-03-10", "is_rented" : True}, {"id" : 4, "related_object" : 2, "start_date" : "2021-03-15", "is_rented" : False}, {"id" : 5, "related_object" : 2, "start_date" : "2021-03-16", "is_rented" : True}, {"id" : 6, "related_object" : 4, "start_date" : "2021-03-16", "is_rented" : False}, {"id" : 7, "related_object" : 2, "start_date" : "2021-03-17", "is_rented" : False}, {"id" : 8, "related_object" : 4, "start_date" : "2021-03-22", "is_rented" : True}, I want to be able to perform the following queries: For a provided date, … -

How do I solve 'Model' object has no attribute 'object' for UpdateView for formset handling?

Annotating with the count of a subquery filtering by jsonb fields in Django
I have a single model with a jsonb field. There is a value inside this jsonb field that can be shared amongst other rows. I am trying to get the count of a subquery while filtering by this jsonb field. Some pseudo code of what I have been attempting borrowing examples from this post. alpha_qs = MyModel.objects.filter(class_id="ALPHA") # unnest jsonb field so I can leverage it via OuterRef alpha_qs = alpha_qs.annotate(nested_value_id=KeyTextTransform("nested_value_id", "a_jsonb_field")) related_beta_subquery = MyModel.objects.filter(class_id="BETA", a_jsonb_field__nested_value_id=OuterRef("nested_value_id")) related_beta_subquery_count = related_beta_subquery.annotate(count=Count("*")).values("count") alpha_qs = alpha_qs.annotate(related_beta_count=Subquery(related_beta_subquery)) Using this example data I would expect the top instance to have a related_beta_count of 2 because there are two associated betas with the same nested_value_id. { "class_id": "ALPHA", "a_jsonb_field": { "nested_value_id": 'abc' } } { "class_id": "BETA", "a_jsonb_field": { "nested_value_id": 'abc' } } { "class_id": "BETA", "a_jsonb_field": { "nested_value_id": 'abc' } } { "class_id": "BETA", "a_jsonb_field": { "nested_value_id": 'zyz' } } I've been getting an error below but haven't been able to resolve it.

Django Combine Window Functions with Standard annotations
I have a Django Model I'm trying to implement a Windows Function and a standard Annotation on. Ideally I want to return a ranking of rows and get an aggregation of another column in the same queryset. As an example mapped below: queryset = ProductData.objects.values('date','sku) .annotate(row_number=ExpressionWrapper(Window(expression=RowNumber(), partition_by=[F('sku')], order_by=F('date').asc()), output_field=FloatField())) .annotate(units_sold=ExpressionWrapper(Sum(F('units_sold')), output_field=FloatField())) .order_by('date','sku') The resulting posted query is: SELECT product_data.SKU, DATE_FORMAT(product_data.date, '%Y-%m-%d') AS date, ROW_NUMBER() OVER (PARTITION BY product_data.SKU ORDER BY product_data.DATE ASC) AS row_number, SUM(product_data.Units_Sold) AS Units_Sold FROM product_data GROUP BY product_data.SKU, DATE_FORMAT(product_data.date, '%Y-%m-%d'), ROW_NUMBER() OVER (PARTITION BY product_data.SKU ORDER BY product_data.DATE ASC) ORDER BY date ASC, product_data.SKU ASC ** When running this method I get the following error: Error Code: 3593. You cannot use the window function 'row_number' in this context.' The query needs to be: SELECT product_data.SKU, DATE_FORMAT(product_data.date, '%Y-%m-%d') AS date, ROW_NUMBER() OVER (PARTITION BY product_data.SKU ORDER BY product_data.DATE ASC) AS row_number, SUM(product_data.Units_Sold) AS Units_Sold FROM product_data GROUP BY product_data.SKU, DATE_FORMAT(product_data.date, '%Y-%m-%d') ORDER BY date ASC, product_data.SKU ASC The problem is that the first annotation defined by the Windows Function creates a new "value Column". So in django by defualt when I call the second annotation it performs a group by on all the Value fields. In django … -

What is the proper way to create draft page programatically in the Wagtail?
Just to save page I do: parent_page = Page.objects.get(title="parent") page = Page(title="child", owner=request.user) parent_page.add_child(instance=page) page.save() # not sure if this required What if I need to save Draft Page? This code seems to be working but I am not sure if it's correct: parent_page = Page.objects.get(title="parent") page = Page(title="child", live=False, owner=request.user) parent_page.add_child(instance=page) page.save_revision() page.save() Do I need call page.save() after page.save_revision()? With this code everything works ok in my case but I have noticed that PageRevision.user_id is empty. How it can affect my code in future? From wagtail code I see that I can save revision with user parameter: page.save_revision(user=request.user, log_action=True) I have saved revisions without user and don't see any side effect. How this field is critical? Do I need to fill user_id field for all existing revisions? P.S. looks like it would be better to wrap this code in transaction because when it fails due to validation error manage.py fixtree show me error Incorrect numchild value. -

DRF: Why does view return "<Response [200]>" rather than string?
I have the following view: @api_view(['POST']) @csrf_exempt def like_view(request, pk, destination): #destination is the user_id post = Posts.objects.get(pk=pk) if check_self_action(destination,post): print("self action!") return Response({"message","cannot like own post"}) if post.is_expired == True: print("expired") return Response({"message","post expired"}) liked = check_like(destination, post) if liked: post.likes.remove(destination) else: post.likes.add(destination) return JsonResponse({"Message":f"Post {pk} successfully liked by {destination}"}) As you can see I expect a response of the form {"Message":f"Post {pk} successfully liked by {destination}"} However, the response I get looks like this <Response [200]> Can you see or suggest why I am not getting the response I expect? Another clue might be that I have an almost identical view called dislike_view which gives me the exact response I expect.
