Why django translations don't work in celery task
I'm having problems with django text translations. My translation works fine in serializer, not in celery task. I have one "Person" model. There are 3 fields in the Person model. One of the fields is gender. The genders are defined in the "enums.py" file. In the serializer, the "get_gender_display()" method of the "Person" model works fine, but when I do the same in the celery task, it does not translate. It doesn't work even though I specify activate("tr") in the Celery task. I call the celery task from the serializer's create() method enums.py from django.utils.translation import gettext_lazy as _ class GenderTypeEnum: FEMALE = 1 MALE = 2 UNKNOWN = 3 types = ( (FEMALE, _("Female")), (MALE, _("Male")), (UNKNOWN, _("Unknown")) ) models.py from django.db import models from .enums import GenderTypeEnum from django.utils.translation import gettext_lazy as _ class PersonModel(models.Model): name = models.CharField( max_length=75, verbose_name=_('Name') ) last_name = models.CharField( max_length=75, verbose_name=_('Last Name') ) gender = models.PositiveIntegerField( choices=GenderTypeEnum.types, default=GenderTypeEnum.UNKNOWN, verbose_name=_('Gender') ) tasks.py from celery import shared_task from .models import PersonModel from django.utils.translation import gettext_lazy as _, activate, get_language @shared_task def test(): activate("tr") qs = PersonModel.objects.all() activate("tr") print(get_language()) # --> tr for obj in qs: print(obj.get_gender_display()) # --> always english, not translated serializers.py from rest_framework … -
Django debug toolbar not showing
My file directory system I have attached my file directory system. I have tried removing all *.pyc files as asked in some of the threads on the same topic, but the toolbar still doesn't show. The following is my webpage code: <html> <body> {% if name %} <h1>Hello {{ name }}!</h1> {%else%} <h1>Hello Dude!</h1> {% endif %} </body> </html> I tried adding mimetypes, adding the following code, and even editing the registry editor, but none of them are working. DEBUG_TOOLBAR_CONFIG = { "INTERCEPT_REDIRECTS": False, } No matter what I do, the browser console displays the following (though when I sometimes change the code the error doesn't get displayed, but neither does the toolbar). I'm using MS Edge, just in case it helps. Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec. toolbar.js:1 When I try importing django in my virtual env, it says that there is no module called 'django'. I've tried all methods possible, but nothing seems to be working. -

Migration fails when using GeoDjango's PointField in a model
I have defined a Model like this (note the I have to specify the schema it should be created on during migration): from django.db import models from django.contrib.gis.db import models as gis_models class MyModel(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) ... geometry = gis_models.PointField() class Meta: db_table = 'gis"."my_model' I make the migration and all seems well. When I run the migration though, I have this error: psycopg2.errors.SyntaxError: syntax error at or near "." LINE 1: CREATE INDEX "gis"."my_model_geometry_id" ON "... (Yes, the error message is truncated like this.) It seems it wants to create an index for the geometry id and fails doing so. I tried to look for this error, but couldn't find anything helpful for this specific case. How can I fix this issue ? -

How to prevent datatable search and pagination rows from repeating when pressing previous or forward buttons?
I am experiencing an issue with JQuery Datatables. Indeed, I am working on a django and Htmx project that has a base template. Inside of it, I initialize datatables like this: $(document).ready(function() { $('#datatable').DataTable({ }); }) Now, given that I am using HTMX, I have a #main-content id on an html element where I replace the content that is returned when Htmx issues an Hx-get request. Each time a request is made, I have to reinitialize the table in the returned template inside a <script><script/> tag using the same code as above and everything works perfectly fine. However, when I press the previous or next browser buttons, the datatable search and pagination rows get repetead multiple times, when there is data in my table, but it doesn't when there is no data. Thank you for helping me. I've tried to destroy the table using the destroy() method inn Javascript, but I still had the same issue. -

Is there an option for alter table in django?
I have a very complicated cyclic dependency issue and I can't use late initialization (encapsulating the table name in quotations) because of some other dependencies on the table so the only logical solution to solve cyclic dependency at this point is to delay the creation of the foreign key through an alter table migration but i can't seem to find a way. just for clarification I want a way in django to execute the SQL command ALTER TABLE, please don't try to solve my cyclic dependency issue some other way i have exhausted every other option. I know there is a way for it in laravel and most major backend frameworks i just can't find anyway to achieve it in django. -
Django : How to filter in between 2 same objects in 2 different models?
I have integrated Microsoft Graph API with my django project and after login in successfully, I am storing both access and refresh token in 2 different models. the models are ModelA and ModelB. Assume that microsoft organisation account holders get their access and refresh token saved in ModelA. The ModelA includes the following attributes: class ModelA(models.Model): active = models.BooleanField(null = True , blank = True) for_user = models.ForeignKey(ModelX, null=True, blank=True, on_delete=models.CASCADE) for_firm = models.ForeignKey(ModelMain, related_name="microsoft_for_firm", null=True, blank=True, on_delete=models.CASCADE) access_token = models.TextField(null=True, blank=True) refresh_token = models.TextField(null=True, blank=True) and microsoft personal accounts holders get their access and refresh tokens saved in ModelB. The ModelB includes the following attributes: class ModelB(models.Model): active = models.BooleanField(null = True , blank = True) for_user = models.ForeignKey(ModelX, null=True, blank=True, on_delete=models.CASCADE) for_firm = models.ForeignKey(ModelMain, related_name="microsoft_for_personal", null=True, blank=True, on_delete=models.CASCADE) access_token = models.TextField(null=True, blank=True) refresh_token = models.TextField(null=True, blank=True) What I want to Achieve? I want to open a docx file using either microsoft organisation or personal account. before opening the file, I want to let the user open the file according to their account type. If a account type is personal, then it should use ModelB's access_token or refresh_token. If an account type is organisation then it should use the … -
