django import-export how to add foreing key
I am using django-import-export to import an excel to my model, what I do is that I create a form with some inputs from where it loads the file, then in form_valid() I process the file to load it to the database, the model has two foreign keys 'id_order' and 'gestion'; 'id_orden' comes in the excel and 'gestion' I get it with gestion= Gestion.objects.get(idgestion=obj.pk) which is the id of the form that I am saving, but what I want to know is how I can pass 'gestion' to ModelResource and then save it to the database view.py class GestionView(CreateView): model = Gestion form_class = GestionForm template_name = 'asignacion/gestion.html' success_url = reverse_lazy('asignacion_url:gestion') def form_valid(self, form): isvalid = super().form_valid(form) obj = form.save() gestion= Gestion.objects.get(idgestion=obj.pk) file = self.request.FILES['file'] item_gestion =ItemResourceResource() dataset = Dataset() imported_data = dataset.load(file.read(), format='xls') result = item_gestion.import_data(dataset, dry_run=True) if not result.has_errors(): item_gestion.import_data(dataset, dry_run=False) model.py class ItemGestion(models.Model): idgestion = models.AutoField(primary_key=True) numero_imagenes = models.CharField(max_length=45, blank=True, null=True) id_orden = models.ForeignKey('Asignacion', models.DO_NOTHING) aviso_sap = models.CharField(max_length=45, blank=True, null=True) poliza = models.CharField(max_length=45, blank=True, null=True) observacion_cierre = models.CharField(max_length=250, blank=True, null=True) gestion=models.ForeignKey('Gestion', models.DO_NOTHING) resources.py class ItemResourceResource(resources.ModelResource): id_orden = fields.Field(column_name='id_orden', attribute='id_orden', widget=ForeignKeyWidget(Asignacion,'id_orden')) class Meta: model = ItemGestion import_id_fields = ('id_orden',) exclude = ('idgestion', ) -
Django Ajax Dropdown Select2 not return data
There is a dropdown form that I created with ajax. The form works without using the Select2 tag and returns data. But when I enter the select2 tag, it does not show the detail that should be displayed according to the selection. I use select2 for all select fields in the system. That's why I defined the select2 tag on my layout template like this. <script> $('.select').select2({ allowClear: true }); </script> Here is my ajax code : <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script> $("#id_worksite_id").change(function () { const url = $("#subunitForm").attr("data-subunit-url"); const worksiteId = $(this).val(); $.ajax({ url: url, data: { 'worksite_id': worksiteId }, success: function (data) { $("#id_upper_subunit_id").html(data); } }); }); Thank you for your help, best regards -
Form fields not showing when including form template
The form fields don't show when including form in another template.

The form shows when in its own url, but not when included in another template (this other template has no other forms). What am I missing? -

Introspect related model to determine name of attribute for reverse descriptor?
Given schema: class User(models.Model): name = models.CharField(max_length=50) class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) User objects will end up having a post_set attribute of type: django.db.models.fields.related_descriptors.create_reverse_many_to_one_manager.<locals>.RelatedManager Which returns a RelatedManager based on Post's default manager. Cool. Q: But if you're trying to introspect on a schema, how do you determine that the attribute name is "post_set"? When I call User._meta.get_fields(), I see a field called "post", not "post_set". (Of type: django.db.models.fields.reverse_related.ManyToOneRel) I've explored nearly all of ManyToOneRel's API, and can't find any attribute or method that will return the value "post_set", only "post". -
NextJS using Django API - How to choose best pattern
I have GeoDjango running on a digital ocean droplet and I'm rewriting project from VueJs to NextJs hosted on Vercel. In Vue we have service pattern connected with store that is responsible for fetching and updating data. I figured out the fetching part which is quite good but I'm still trying to figure out the best way to update data. How should I construct the CRUD layer without using the NextJs API folder ( I don't want to have another backend calling my Django backend). Should I use context? Should I use middleware? Should I create custom services? How to call them then? Is there an equivalent of store in NextJs? I'm asking because I want to avoid cluttering as right now I'm using fetch POST on pages. I'm using NextAuth that gives me a context with jwt token. Thank you for any hints -

Document more than one repos with MkDocs
I got a special situation where I have a few Django packages that work closely together, and I want to document them together at one place. medux-common: common used models, views, etc. medux: main application medux-online: web interface for certain functions medux-docs: the documentation package Both medux-online and medux use the common module, and I don't want to have 3 documentation homepages, but just one where all is documented at one place. Is there a possibility in MkDocs to "load" external packages? I use the mkdocstrings plugin to load the docstrings from my code. Its docs says, that the path must be set so that the module to document must be importable. In my medux-docs package, I import all the other packages using pip install -e ../medux etc., which works fine. But MkDocs does not find them: $ mkdocs serve [...] ERROR - mkdocstrings: medux.core.middleware could not be found ERROR - Could not collect 'medux.core.middleware' How do I do that? I don't want to merge all repositories into one, as medux and medux-online should be 2 pypi packages too. I just want MkDocs to find the imported medux, medux-online, and medux-common. Do I completely think the wrong way? -
Django-Quill-Editor not rendering text into webpage
I added Quill Editor to my admin panel to post blogs on my django project. But the text doesn't render. once I add the .html and |safe I get a parser error. If I remove the .html it just doesn't render. Any ideas? Strange thing is that this is working on my production server, but not local, which isn't ideal as I would like it working for testing.

Django: Can I change one request in the template and then call the view again? It shall be a loop betwen view and template where one attribute changes
In views.py I use a POST request that specifies the settings for the game. The game function starts the game with these settings. In the template, I want to call the game function again after every round and increase the value of the current round. So in the template I need to submit the form again with the same values from the former request and only increase the value of currentround. I tried to insert the same form in the template and fill it with the values that were put into the former form. Then, only change the value of the current round. Should I create a model for every game that is set up instead and increase the counter in there or is it possible to change the request from round to round for one attribute while maintaining all the other ones? -
Is it possible to get N number of records per a value in a joined table WITHOUT multiple queries?
So I have three tables: article_page - (for my articles) represented by the model Page article_page_category - glue table between article_page and article_category as they're many to many article_category - category information, represented by the model Category I want to make a query to the database that gets N number of records (10 to 20 probably) PER category, preferably in one query, as I can have a lot of categories at once, and this can be quite expensive. I've been trying all sorts of different types of queries and I'm having no luck - I've even tried various subqueries but that didn't translate amazingly well to Django, and raw sql queries were difficult to get working. To give an example: So let's say I have the categories of business, technology, sports I want to get 10 articles from business, 10 from technology, and 10 from sports - all of which are categories in article_category Is there a way to do that with one query? I've got something like this right now, but I really think this isn't the right approach: class GroupedArticleListView(APIView): def get(self, request): categories = Category.objects.filter(taxon=1) categories = categories.annotate( top_articles=Subquery( Page.objects.filter( category=OuterRef("pk") ).order_by("-date").values_list("id", flat=True)[:10].first(), output_field=IntegerField() ) ) The … -

Login page is showing errors on redirect instead of showing errors on login
I'm completely stumped here. So I copied and pasted this code from another project but on this project for some reason when I enter an incorrect user/pass combo it redirects to anther page then shows the errors there instead of just reloading the login page and displaying the errors there. On the other project, the view reloads the login view with the errors. I'm using Django 3.2 on both projects class LoginView(FormView): form_class = LoginForm template_name = 'users/forms/login.html' success_url = reverse_lazy('blog:index') def dispatch(self, request, *args, **kwargs): if self.request.user.is_authenticated: return redirect('blog:index') return super(LoginView, self).dispatch(request, *args, **kwargs) def form_valid(self, form): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = authenticate(username=username, password=password) if user is not None: if user.is_active: login(self.request, user) return redirect('blog:index') else: messages.error(self.request, "Your account is not active, please contact an administrator", extra_tags='alert alert-danger') else: messages.error(self.request, "Username/Password is invalid", extra_tags='alert alert-danger') return super(LoginView, self).form_valid(form) I am displaying the messages in the login template. The messages are working, they're just not reloading the login view, instead it takes me to the success url! What am I missing? This is literally the exact same code I'm using on another project and it's working as expected. -

Custom django data migration creating records allauth.account EmailAddress model returns error - django.db.migrations.exceptions.NodeNotFoundError:
I am upgrading a django project that was created with the default django auth. Email verification was implemented with the django.contrib.auth.tokens package. The way it worked was that the 'is_active' flag of the default django user which itself is extended with a custom user is initially set to False and changes to True after the user verifies the email. Now, I have upgraded the project to use django-allauth, gotten every thing else to work just fine (in development), EXCEPT the email verification. Since django-allauth extends the User model with the EmailAddress model and checks 'verified' flag on this model to determine if an email has been verified/confirmed, I decided to write a custom data migration which creates the records in the EmailAddress table and sets verified = True if user.is_active = True. However, I get the error below: django.db.migrations.exceptions.NodeNotFoundError: Migration accounts.0003_create_allauth_email_records_for_existing_users dependencies reference nonexistent parent node ('allauth.account', '0002_email_max_length') accounts/migrations/0003_create_allauth_email_records_for_existing_users.py # Generated by Django 3.2.11 on 2022-12-09 10:56 from django.db import migrations class Migration(migrations.Migration): dependencies = [ ('accounts', '0002_delete_profile'), ('allauth.account', '0002_email_max_length') ] def create_allauth_email_records_for_existing_users(apps, schema_editor): UserModel = apps.get_model("accounts", "User") EmailMoldel = apps.get_model("allauth.account", "EmailAddress") for user in UserModel.objects.all(): email_record = EmailMoldel.objects.filter(email=user.email).first() if email_record == None: if user.is_active: email_verified = True else: email_verified … -

` my variable productid from ajax data below returns an empty string but my aim is to return product id from django sessions when user clicks the add-to-cart , <script> $(document).on('click', '#add-cart-btn', function (e) { e.preventDefault(); $.ajax({ type: "POST", url: "{% url 'storebasket:add_to_cart'%}", data:{ productid: $("#add-cart-btn").val(), csrfmiddlewaretoken: "{{csrf_token}}", action: "post" }, success: function(json){ }, error: function (xhr, errmsg, err) {} }); }) </script>` ` Here is the error raised: ` ` File "C:\Users\DELL\Documents\PROGRAMMING\VSCODE\PYTHON\ecommerce\storebasket\views.py", line 19, in add_to_cart product_id = int(request.POST.get('productid')) ValueError: invalid literal for int() with base 10: '' ` The view that raises the error: # capture ajax data def add_to_cart(request): basket =MySession(request) if request.POST.get('action') == 'post': product_id = int(request.POST.get('productid')) product=get_object_or_404(Product, id=product_id) # save to MySession basket.add(product=product) response=JsonResponse({'test': 'data'}) return response My session creation code is as follows: class MySession(): def __init__(self,request): self.session=request.session basket=self.session.get('S_key') if 'S_key' not in request.session: basket=self.session['S_key']={} self.basket=basket #request.session.modified = True def add(self, product): """ Adding and updating the users basket session data """ product_id = product.id if product_id not in self.basket: self.basket[product_id] = {'price': str(product.price)} # save in the session self.session.modified = True class MySession(): def __init__(self,request): self.session=request.session basket=self.session.get('S_key') if 'S_key' not in request.session: basket=self.session['S_key']={} self.basket=basket #request.session.modified = True def add(self, product): """ Adding and … -
'datetime.datetime' object has no attribute 'strip'
I created an update form, the form has 2 time field and 2 date time field, once click on submit even nothing change, I got an error "'datetime.datetime' object has no attribute 'strip'". but there is no error when creating a new object for the same model . modles: time_start=models.DateTimeField(blank=True,null=True) htime_start=models.TimeField(blank=True,null=True) time_end = models.DateTimeField(blank=True, null=True) htime_end=models.TimeField(blank=True,null=True) time_require=models.DateTimeField(blank=True,null=True) machine=models.ForeignKey(Machine,null=True, on_delete=models.SET_NULL, blank=True) forms: class AssignTimeForProjects(forms.ModelForm): title = forms.CharField(disabled=True) owner=forms.CharField(disabled=True) time_require=forms.TimeField(disabled=True) class Meta: model = tb_order # fields='__all__' fields = ['title', 'owner', 'grade', 'quantity', 'time_require','htime_start','color', 'mould','time_start','time_end', 'htime_end' ,'machine'] def __init__(self, *args, **kwargs): super(AssignTimeForProjects, self).__init__(*args, **kwargs) self.fields["time_end"] = JalaliDateField(label=('تاریخ اتمام'), widget=(AdminJalaliDateWidget)) self.fields["time_start"] = JalaliDateField(label=('تاریخ شروع'), widget=(AdminJalaliDateWidget)) Html: <label>{{ form.htime_start.label}}</label> {% render_field form.htime_start type="time" class+="form-control timepicker" autocomplete="off" %} <br> <label>{{ form.time_end.label}}</label> {% render_field form.time_end class+="form-control" autocomplete="off" %} <br> <label>{{ form.htime_end.label}}</label> {% render_field form.htime_end type="time" class+="form-control" autocomplete="off" %} -
Why .last()/.first() change the order of the ordered and distinct queryset?
I have query like this - it needs to filter values by date and in case we have priorities on dates (x), we are setting up proper order which data we need. def filterX(self, order_list=[3,2,1], *args, **kwargs): return ( self.get_queryset() .filter(*args, **kwargs) .order_by( "date", Case( *[ When(x=y, then=Value(i)) for i, y in enumerate(order_list) ], default=None, ).asc(), ) .distinct("date") ) So I need only one item per one date with highest order given. And it works perfectly. From table 1 I have table 2 -> Table 1. ID DATE PRIORITY 1 2022/11/1 1 2 2022/11/1 2 3 2022/11/1 3 4 2022/11/2 2 5 2022/11/3 1 6 2022/11/3 2 Table 2. ID DATE PRIORITY 1 2022/11/1 3 4 2022/11/2 2 5 2022/11/3 2 But if I use this query for one date I get queryset with one item (which I need), but after .last the item is actually changed. Any advices?
