django-cms makemigrations error: No module named 'packaging'
I am starting out in django-cms and I am trying to install cms from the official cms documentation. I created my virtual environment and installed Django and django-cms.

Return QuerySet with extra pagination fields
My get_queryset return this. Also, this fields with ID's are foreign keys serialized. [ { "id": 1389, "nome": "Curso teste", "nivel": { "id": 5, "nome": "Ensino Fundamental II" }, "modalidade": { "id": 4, "nome": "Presencial" }, "periodo": { "id": 5, "nome": "Matutino" }, "ano": { "id": 21, "nome": "12º Semestre" }, "instituicao": { "id": 35, "nome": "Fncit-escola" } } ] I want to add to each object an extra pagination object, and it would be like this object below. But get_queryset do not accept this kind of object, and if I use just get, and serialize the queryset, it will not come with the ForeignKeys serialized, it will return only the id's of the Foreign keys. Anyone knows how do I return an object like this?

django haystack rebuild_index fails if model id exluded
I'm trying to understand a rebuild_index error that results when using a very basic SearchIndex very similar to what is used in the haystack documentation. In the docs, the id of the model is excluded, which makes sense given that there seems little point in it influencing search results. I've tried something like this class CollectionIndex(indexes.SearchIndex, indexes.Indexable): #id = indexes.IntegerField(model_attr='pk') text = indexes.CharField(document=True, use_template=True) name = indexes.CharField(model_attr='name') def get_model(self): return Collection def index_queryset(self, using=None): # force just one item to be indexed to save a wait. return self.get_model().objects.filter(name="Test") ...but I get this error (I've applied some formatting to help legibility) elasticsearch.helpers.BulkIndexError: ('1 document(s) failed to index.', [ { "index": { "_index": "haystack", "_type": "modelresult", "_id": "my_project.collection.1", "status": 400, "error": { "type": "mapper_parsing_exception", "reason": "failed to parse [id]", "caused_by": { "type": "number_format_exception", "reason": 'For input string: "my_project.collection.1"', }, }, } } ]) The only way to get the indexing to work is to uncomment the id line. Is this just an elasticsearch thing, which is why the examples in the official docs don't have an equivalent, or am I misinterpreting things? Does it make sense to do a search for a number, and have a search result with an id matching … -
Force user to re-login when accessing admin page on Django
I have a django project that I want to force an administrator to login before accessing the admin area EVEN IF they are already logged into to the main site. The approach I have thought of was to creating a custom admin view where I logout the user (if they are already logged in) when they try to access the admin page but not sure what the cleanest way of doing this is. Currently my urls.py for admin is just url(r'^admin/', admin.site.urls) My ultimate goal is to have 2FA implemented just for my admin login. -
Psycopg2 duplicate key value violates unique constraint (when migrating from SQLITE to POSTGRESQL)
I have been trying to migrate a database from SQLite to POSTGRESQL. I am using json fixtures to dump and load the data, I tested multiple ways but I end up in a similar situation, and I say similar because I can reach 2 slightly different errors. So the 2 errors I can reach are the following: django.db.utils.IntegrityError: Problem installing fixture '/PATH/wcontenttypes.json': Could not load MyApp.DIN_STATUS(pk=1): duplicate key value violates unique constraint "MyApp_din_status_DSP_id_EA_id_1c1c3e96_uniq" DETAIL: Key ("DSP_id", "EA_id")=(542, 20324) already exists. The other one is the same but instead of pk=1, its pk=5 What did I check? If there's a duplicate -> but there is not If the row referenced by the id exist -> it does exist Removing the row that gives the error -> The next one gives the error (in case its pk=5, then pk=6, if pk=1 then pk=2) What did I test?

Multiple permission to view/add/change a model class object
I am trying to edit permissions from the admin-site for a specific group in my project. (Specifically the Manager group) I noticed that for this one model class named DeliveryOrderForm, contains two instances of one permission. For example : deliveryorder| delivery order form | can add delivery order form deliveryorder| delivery order form | can add delivery order What I understand is that the first part 'deliveryorder' is referencing the application name, the second part is referencing the model's class name, but I am unsure what the 3rd part is referencing to. These are the attributes for my class DeliveryOrderForm model class DeliveryOrderForm(models.Model): deliveryOrderID = models.AutoField(unique=True,primary_key=True) vendorName = models.CharField(max_length=30) vendorAddress = models.CharField(max_length=200) recipientName = models.CharField(max_length=30) recipientPhone = PhoneNumberField(blank=False) recipientAddress = models.CharField(max_length=200) deliveryOrderStatus = models.IntegerField(default=Status.pending,choices=Status.choices) deliveryOrderDate = models.DateTimeField(default=timezone.now()) I hope someone can help me understand this cause I'm afraid if my model is actually screwed up. -

I'm working on my Django blog, and when I go to categories I listed all posts in that category, but for some reason I cannot manage to work pagination. Everything works except one thing, on all pages I can see all posts, but I want to see only 6 posts per page. This is pagination.html that is included in category detail page <div class="mb-30"> <nav aria-label="Page navigation example"> <ul class="pagination justify-content-start"> {% if category_page.has_previous %} <li class="page-item"><a class="page-link" href="?page={{ category_page.previous_page_number }}"><i class="ti-angle-left"></i></a></li> {% else %} <li class="page-item"><a class="page-link" href="#"><i class="ti-angle-left"></i></a></li> {% endif %} {% for i in category_page.paginator.page_range %} {% if category_page.number == i %} <li class="page-item active"><a class="page-link" href="#">{{ i }}</a></li> {% else %} <li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li> {% endif %} {% endfor %} {% if category_page.has_next %} <li class="page-item"><a class="page-link" href="?page={{ category_page.next_page_number }}"><i class="ti-angle-right"></i></a></li> {% else %} <li class="page-item"><a class="page-link" href="#"><i class="ti-angle-right"></i></a></li> {% endif %} </ul> </nav> </div> This is category_detail.html {% for post in posts %} <article class="col-lg-10"> <div class="background-white"> <div class="post-thumb"> <a href="{{ post.get_absolute_url }}"> <img class="border-radius" src="{{ post.image.standard.url }}" alt=""> </a> </div> <div class="pl-10"> <div class="mb-15"> <a class="meta-2" href="{{ post.category.get_absolute_url }}"><span class="post-in">{{ post.category}}</span></a> </div> <h5 class="mb-15"> <a href="{{ post.get_absolute_url }}">{{ post.post_title … -
Django - Annotate within for loop - what is the difference between my two codes
I am trying to sum up two columns in a view with values() and annotate(). Column 1 Column 2 5 0 5 -2 Currently calling "total" will return the total for each row and not the overall total. Returning in template 5 3 I believe this is because I print the total in a for loop. What confuses me is that I have an almost similar code working perfectly fine in another view. How can I get the total of the several rows together? views def function(request, userprofile_id): venue = UserProfile.objects.filter(user=request.user).values('venue') points_cummulated_per_user_per_venue = Itemised_Loyalty_Card.objects.filter(user=userprofile_id).filter(venue=request.user.userprofile.venue).values('venue__name','timestamp').annotate(sum_points=Sum('add_points')).annotate(less_points=Sum('use_points')).annotate(total=F('add_points')-F('use_points')).order_by('-timestamp') return render(request,"main/account/venue_loyalty_card.html",{'venue':venue,'points_cummulated_per_user_per_venue':points_cummulated_per_user_per_venue}) template {%for model in points_cummulated_per_user_per_venue %} Total: {{model.total}} {%endfor%} -
Creating an "incomplete" Django class for a user to fill in
I have a database representing financial transactions. Columns representing payee and category are non-optional. However, part of my app's functionality will be to ingest external spreadsheets of transactions which do not already have payee and category information. I would then populate a form where the user will select correct payees and categories through drop-down menus, and then save the completed information to the database. Is the correct approach to simply create two separate but equivalent classes (see below)? Or is there some way to make one a sub-class to another, despite the fact that one is connected to a database and the other is not. # An initial class representing a transaction read from an Excel sheet # Payee and category information are missing at this stage, but will be filled # in by the user later on class TransactionFromSpreadsheet: def __init__(self, date, amount): self.date = date self.amount = amount self.payee = None self.category = None # The Django class that will be instantiated once all the user has completed all # necessary information class Transaction(models.Model): date = models.DateField() amount = models.DecimalField(max_digits=14, decimal_places=2) category = models.ForeignKey('Category', on_delete=models.CASCADE) payee = models.ForeignKey('Payee', on_delete=models.CASCADE)
