no module named 'multiselectfield' (docker / Django)
I am trying to run a database on my server using docker. I am using django and postgreSQL.

Filter Embedded Documents that match a condition in MongoEngine, Django, GraphQl

How to test foreignkeys to self in django
Django allows a foreign key to "self" as in class Profile(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE, verbose_name="User", related_name="user_profiles", ) entity = models.ForeignKey( Entity, on_delete=models.CASCADE, verbose_name="Entity", related_name="entity_profiles", ) email = models.EmailField( max_length=255, help_text=_("Automatically generated to use entity email domain"), ) supervisor0 = models.ForeignKey( "self", on_delete=models.CASCADE, null=True, blank=True, verbose_name="Supervisor0", related_name="supervisor0_profiles", help_text=_("Employees only."), ) supervisor1 = models.ForeignKey( "self", on_delete=models.CASCADE, null=True, blank=True, verbose_name="Supervisor1", related_name="supervisor1_profiles", help_text=_( "Employees only. Only the executive head is his/her own \ supervisor." ), ) supervisor2 = models.ForeignKey( "self", on_delete=models.CASCADE, null=True, blank=True, verbose_name="Supervisor2", related_name="supervisor2_profiles", help_text=_( "Employees only.

Only the executive head is his/her own \ supervisor." ), ) The supervisor0 is the user and being supervisor0 identifies him/her as an employee. The other supervisors also have to be already in the database for them to be able to be referenced. The help_texts explain the situation of the executive head. The question is how to test these relationships to "self". I have no problem with relationships to other models. Using pytest, I record only supervisor0 in the ProfileFactory for the moment. class ProfileFactory(factory.django.DjangoModelFactory): class Meta: model = Profile user … -

form.errors won't display upon invalid form submission
I'm having difficulty with displaying custom defined errors on a page when a user submits an invalid form submission. I set novalidate on the form element with the intent of disabling a browser's default form validation messages. At the same time the error messages that are defined on QuestionForm are not displaying on the page. It's not clear to me why the form error messages aren't showing?

Is there a way to override ClockedSchedule model from Django Celery Beat?
I want to add unique=True attribute to clocked_time field of ClockedSchedule model. Current Scenario is, when multiple threads try to get_or_create schedule, it creates more than one of similar records given schedule is not found, and when next time some thread tries to get the schedule it throws MultipleObjectsReturned exception. So, I was thinking adding a DB constraint might work here. Attaching the code for reference: schedule, created = ClockedSchedule.objects.get_or_create(**clocked_options) return schedule And the model looks like: class ClockedSchedule(models.Model): """clocked schedule.""" clocked_time = models.DateTimeField( verbose_name=_('Clock Time'), help_text=_('Run the task at clocked time'), ) class Meta: """Table information.""" verbose_name = _('clocked') verbose_name_plural = _('clocked') ordering = ['clocked_time'] def __str__(self): return '{}'.format(self.clocked_time) Let me know your thoughts, thanks! -
Ajax get request stays on readystate 1, but when i log the response text in the console it displays it without a problem
I cant display the result in my html because the request stays in state 1 and the response text displays undefined. When I access the url it displays the value I want to show on my html. Why is this happening? I'm using django on server side btw. Kinda new to ajax but I haven't been able to find an answer to this problem on other already solved questions. Code that executes the request: const getHighScore = (gameID, levelID) => { let ajaxPrueba = $.ajax({ url: `/get-data/${gameID}/${levelID}`, type: 'get', success: function(data) { return data; }, failure: function(data) { console.log('Got an error dude'); } }); return ajaxPrueba; } The parameters i pass on are 1 for gameID and 1 for levelID The url i'm talking about Also this is what the console returns: ajaxPrueba = $.ajax({ url: `/get-data/1/1`, type: 'get', success: function(data) { return data;… Object { readyState: 1, getResponseHeader: getResponseHeader(e), getAllResponseHeaders: getAllResponseHeaders(), setRequestHeader: setRequestHeader(e, t), overrideMimeType: overrideMimeType(e), statusCode: statusCode(e), abort: abort(e), state: state(), always: always(), catch: catch(e) , … } abort: function abort(e) always: function always() catch: function catch(e) done: function add() fail: function add() getAllResponseHeaders: function getAllResponseHeaders() getResponseHeader: function getResponseHeader(e) overrideMimeType: function overrideMimeType(e) pipe: function pipe() progress: function … -
Deserializing json to a python object without actually save the object in DB
I use Django and the model classes to access data from DB. I would like to add cache layer on top of DB. For example, let's say I have a User model and UserSerializer (inherited from ModelSerializer). When storing an User object in cache, I need to serialize the object to json import json serializer = UserSerializer(obj) serialized_data = json.dumps(serializer.data) However, when I retrieve this json from cache, I had trouble to convert it back to User object data = json.loads(serialized_data) deserializer = UserSerializer(data=data) user_obj = deserializer.save() # this return an User object but intenally it will create a new record in DB Any better ideas that I can use the serializer that django provided to deserialize json to object without actually creating the record in DB? -
Hyperlinks in Django Quill Editor are not displaying as expected
Problem I added the Quill Editor to my Django admin. When I input hyperlinks in the QuillEditor such as "www.example.com", instead of creating the hyperlink exactly as I type it, the URL will appear on the template page as "localhost:8000/plants/www.example.com". Directing me to a broken page instead of www.example.com Context I've read through the full quill documentation but I don't see a way to make sure hyperlinks added in the QuillEditor display without the project domain being prepended to the front of the hyperlink url.

Wrap python decorator with another decorator

Is there an efficient way to get the Django model of a modeladmin object from within an Admin action?
I have an action that is added to multiple Django model admins. Part of that action relies on the modeladmin and queryset like so: def my_action(modeladmin, request, queryset): queryset_model_name = queryset.first().__class__.__name__ model_to_update = apps.get_model(app_label='main', model_name=queryset_model_name) # more code here that relies on both queryset_model_name and model_to_update Is there a way to refactor this? Possibly a way to get the model string itself directly from modeladmin instead? I did a search through the django doc page for ModelAdmin but came up short. Any assistance would be appreciated! Thank you in advance. -

Django: Code only executing on watcher reload?
I'm working with Django and I have code that I'm attempting to execute on page load, but it isn't executing.

Access domain (and port) URL in settings.py file while in localhost development
How do you dynamically access the domain name URL in the settings.py file of Django? (ie "http://localhost:8000") I am trying to overwrite a package CDN while the internet is unavailable during development, and want to point to the local file in the static files directory. While os.path.join(BASE_DIR, "path/to/local.file") should work, it is context-dependent as to which app/url (ie "http://localhost:8000/app/static/css/bootstrap.min.css "), and not just the main domain with the static file location appended to the starting server with ./manage.py runserver 0:8000 (ie " http://localhost:8000/static/css/bootstrap.min.css"). Notes: Because this is in the settings.py, I can't load any apps or reverse because of the error *** django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. I am not in a template, so I can't use the static url statically defining it won't allow for different port loadings when starting via ./manage.py runserver 0:8000 Basically in the settings.py file: # If in local dev if "RDS_DB_NAME" not in os.environ: # the setting for the package I am pointing to a local version BOOTSTRAP5 = { "css_url": { ### dynamically get domain here ### # "href": os.path.join(LOCAL_DIR, "static/css/bootstrap.min.css"), "href": "static/css/bootstrap.min.css", } -
Django model form won't save/validate
I am new to Django and I have a comments form on a listing page of a marketplace site I am working on. When trying to enter a comment they don't save. I assume the is_valid() is not returning True so the saving never occurs, but I don't see why it wouldn't be valid. I thought that function primarily checked all fields were filled with valid data. As I said I'm new to Django so any advice would be appreciated. The Else redirect is temporary until I get it working correctly. Views.py @login_required def comment(request, listing): listing = AuctionListings.objects.get(name=listing) form = NewCommentForm(request.POST) if form.is_valid(): comment = form.save(commit=False) comment.user = request.user comment.listing = listing comment.save() return HttpResponseRedirect(reverse("listing", args=[listing.name])) else: return HttpResponseRedirect(reverse("listing", args=[listing.name])) models.py class Comments(models.Model): listing = models.ForeignKey(AuctionListings, on_delete=models.CASCADE) user = models.ForeignKey(User, on_delete=models.CASCADE) comment = models.CharField(max_length=255, validators=[MinLengthValidator(1)]) date = models.DateTimeField(auto_now_add=True) forms.py class NewCommentForm(forms.ModelForm): class Meta: model = Comments fields = [ 'comment' ] widgets = { 'comment': forms.Textarea(attrs={ 'placeholder': 'Enter your comment (255 char. max)', }) } -
Reliably accessing request.user in Django custom LoginView
I have a custom LoginView and I'd like to take the shopping cart of a LazyUser pre-login and consolidate it with the cart of the user after login: class LoginView(FormView): ... def form_valid(self, form): request_user = self.request.user user = authenticate(email=form.cleaned_data['email'], password=form.cleaned_data['password']) if user is not None: login(self.request, user) try: user.consolidate_carts(request_user) except Exception as e: print('error in consolidate_carts: ', e) return HttpResponseRedirect(self.success_url) else: return render(self.request, 'users/login.html') This seems to work some of the time, but it is unreliable - I believe that is because I am simply referencing self.request.user and it is a SimpleLazyObject. What would be the pythonic/optimal way to store the user pre-login?
