I was trying to do Register and Login form but I am taking "'AnonymousUser' object has no attribute '_meta'" error I hope somebody can help me.

Conditional Boolean Attribute in Django
I want to have a BooleanField private in my models for my project, but I only want to show this, if another field has a particular value. This is my Model: class Scope(models.TextChoices): COMPANY = 'company', _("Company") TEAM = 'team', _("Team") INDIVIDUAL = 'individual', _("Individual") class Objective(models.Model): name = models.CharField(max_length=500, verbose_name=_("name")) scope = models.TextField(_("Scope"), max_length=15, choices=Scope.choices, db_index=True, default=Scope.TEAM) is_private = models.BooleanField(default=False, verbose_name=_("private")) def __str__(self): return self.name Now I only want to show the is_private BooleanField in the Form, when the Scope of the Objective is INDIVIDUAL. How can I do this? -
Handle revoke command from inside task
Is there a way to handle revoke commands inside the task logic? Since I'm doing some computations and database manipulation on RUNNING tasks I'd like to handle a revoke user request using the data of the task itself. I've already tried capturing the celery.exceptions.Terminated or celery.exceptions.WorkerTerminated exceptions but it doesn't seem to work as expected. from celery import shared_task, exceptions @shared_task( name="tasks.trigger_sales", bind=True ) def trigger_sales_job(self): try: logger.info('Executing task id {0.id}, args: {0.args!r} kwargs: {0.kwargs!r}'.format(self.request)) # Do some work on DB return True except (exceptions.Terminated, exceptions.WorkerTerminated) as e: logger.warning(f"Task {self.request.id} has been terminated by user request.") -

Why does Django password reset email not sent to btopenworld?
I'm using the Django built in password reset functions and I'm having a weird thing happen. The emails seem to get sent for some people and not others. I tried the system for myself (I have two email addresses) and the Django password reset function works for one of my addresses and not for the other, i.e. I do not receive an automated email with a link to a password reset facility. I'm having problems with a '@btopenworld.com' address. Is this inconsistency a known problem in Django, or have I likely missed something? All my other email functions in the app work perfectly. Thanks -

In Django how would you setup user permissions for a user to only have access to a rest api?
In our project users can generally login to the system and access vaious web-pages. There is also a rest-api - users can access certain information through rest api as well (token authentication). Now there is one user that only should have api-access - login only through an api call returning the token. Access to web-pages in not desired and should be prevented for this user. How can we set this up? Is it possible right out of the box or is it necessary to adapt permission classes? -
Swagger codegen with write_only PrimaryKeyRelatedField
In our project we have the following case more than once: class TestSerializer(serializers.ModelSerializer): unit = UnitSerializer(read_only=True) unit_id = serializers.PrimaryKeyRelatedField( queryset=Unit.objects.all(), source="unit", write_only=True) This is according to our best practices where variables should describe which type they contain. In drf-yasg this is shown however as required in both the Read and the Write way. This means that code generators will mark this field as required, and when our API response comes in, they invalidate the request, because the unit_id is missing. Is there a way to declare this field as write_only other than this parameter? -
Updating FileField in Django Form
Playing around with FileFiled and trying to update a form. I think my problem comes from the views.py. I have a template where I can see a product, and I have the option to update the product by clicking on the update button. When clicking on the update button, I am redirected to a form where I can update the product. template {% for TermsAndConditions in commercial_list %} <a class="btn btn-outline-secondary" href="{% url 'update-commercial' TermsAndConditions.id %}">Update </a> {% endfor %} My normal upload form (without FileField) looks like this: views (without FileField) def update_commercial(request, termsandconditions_id): commercials = TermsAndConditions.objects.get(pk=termsandconditions_id) form = TermsAndConditionsForm(request.POST or None, instance=commercials ) if form.is_valid(): form.save() return redirect('list-commercial') return render(request, 'main/update_commercial.html',{'form':form,'commercials':commercials}) With the addition of the FileField, I thought I would do something like this: views (with FileField) def update_commercial(request, termsandconditions_id): commercials = TermsAndConditions.objects.get(pk=termsandconditions_id) form = TermsAndConditionsForm(request.POST or None, request.FILES ,instance=commercials ) #the change being request.FILES if form.is_valid(): form.save() return redirect('list-commercial') return render(request, 'main/update_commercial.html',{'form':form,'commercials':commercials}) Problem is, when I do that the update button in the template becomes invalid (it doesn't redirect to the update form). I think my problem is how to handle the or None and request.FILES together. I tried different combinations but none have worked. Hoping … -
Django model forms validation in Django admin enters clean method when model validation has failed
I have a Django admin class defined like this: class MyModelAdmin(admin.ModelAdmin): form = MyForm class MyForm(forms.ModelForm): class Meta: model = Task fields = ('project', 'title', 'description', 'internal_assignees', 'task_list', 'additional_description', 'labels', 'skill_level', 'estimated_hours', 'merge_request_url', 'branch_name',) def clean(self): super().clean() print(self.errors) Assume my model has a required field, which the user does not submit when performing POST request. The expected behavior in this case is that Django will not enter my overriden clean method. But it actually does. And self.errors contain error message. The expected behavior was that Django will not enter the clean method if any of the required fields have not been submitted and will raise Bad request. Do I understand something incorrectly ? If so, does it mean that I have to check whether required fields are not or not in my clean method? -

Change select field options in client script in NetSuite
I have a client script runs on Suitelet. On Suitelet we have a sublist which has many select columns. Let's say we have Select 1 and Select 2. Select 2 options should be different if you change the option in Select 1. Could this be done in Client Script? or in that Suitelet? Any help would be appreciated. ` var select1= sublist.addField({ id: 'custpage_select1', label: 'Select1', type: ui.FieldType.SELECT }); var select2= sublist.addField({ id: 'custpage_select2', label: 'Select2', type: ui.FieldType.SELECT }); ` In client script when the field is changed, I want to change options of Select 2 depend on Select 1. function fieldChanged(scriptContext){ if(scriptContext.fieldId=="custpage_select1"){ let page = currentRecord.get(); var select2 = page.getField({fieldID:"custpage_select2"}); select2.removeSelectOption({value:"value1"}); } } But this shows me an error that Cannot read properties of null Thank you -
Django And Elasticsearch
I am evaluating the opportunity to include some elasticSearch indexes in our Django Backend, I reviewed so far three django apps: django-elasticsearch-dsl elasticsearch-django django-haystack So far, I can't tell if there is such a package not needing to replicate content of the indexes in the django DB, from what I read, it seems like we have to have some standard Relational DB ORM objects attached to each indexes. If I am right, that then implies the data duplication, and potentially a huge one in our case. Is there a way with the mentioned packages to avoid this objects duplication? Or did I misread the whole thing and it's not actually duplicating data? Thanks for your insights! Marc -
