Running Django Server

In Django, when trying to access a model's 1:1 relation that doesn't exist, sometime that relation is None, and sometimes it raises an exception. Why?
I noticed while debugging a Django application that with two tables with a 1:1 relation, trying to access the related object from the table that defines the 1:1 relation would return None, while trying to access the same nonexistent relation from the table that does not define the relation Django will raise a Model1.model2.RelatedObjectDoesNotExist exception. I was confused by this behavior as the same action has two different results on objects on the same type of relation. This is an example of the models used: class RelatedModel(models.Model): pass class RelationshipDefiner(models.Model): related_object = models.OneToOneField( RelatedModel, on_delete=models.CASCADE, related_name="relationship_definer", blank=True, null=True ) This is an example of trying to print the relations to screen: relationship_definer = RelationshipDefiner.objects.create() related_object = RelatedModel.objects.create() print("RELATIONSHIP DEFINER'S RELATED OBJECT:") print(relationship_definer.related_object) print("RELATED OBJECT'S RELATIONSHIP DEFINER:") print(related_object.relationship_definer) And the output: RELATIONSHIP DEFINER'S RELATED OBJECT: None RELATED OBJECT'S RELATIONSHIP DEFINER: Internal Server Error: /test/ File "/django/app/views/test.py", line 17, in test print(related_object.relationship_definer) app.models.sample.RelatedModel.relationship_definer.RelatedObjectDoesNotExist: RelatedModel has no relationship_definer. Why do 1:1 nullable relationships behave differently on either side of the relation, and is there a way to coerce Django to behave consistently across both sides of the relationship? -
Styling a GeoDjango widget with TailwindCSS
I have been trying to style the GeoDjango OSMWidget (for Polygon drawing) for ages but can't work out how to make it flexible. Setting the map width and map height is all fine for a fixed page size but what happens if someone snaps their browser window to half-screen? A fixed map width does not react to these changes and becomes an unwieldily feature so fast it's painful. Here is what the GeoDjango documentation suggests for widget styling: widgets = { 'geometry': forms.OSMWidget(attrs={ 'map_width': 1000, 'map_height': 400, 'default_zoom': 7.5 }), } Other widgets, such as forms.Select have the option for a style attribute where custom css can be defined. The map widgets ignore this completely. How can I force this map widget to respond to my css demands? I want flexible widgets, goddamit! *Bonus points for integration with tailwind -
How to automatically connect a logged in User to submit a document
Please I am new to coding, I am currently working on an app where there are various users trying to submit a document, I want them to be able to view only the documents they upload, while the admin can view all the users' documents. I was able to accomplish this but in this case the user field is a foreign key at the backend, and it's showing a drop down on the front end, I want each user to be automatically assigned to theirs, please how do I accomplish this.

How to indicate required fields on initial form render, using Bootstrap 5 styling and Django?
I am using Django 4.1 and Bootstrap 5. I think I'd like to mark required fields in a form as required, or maybe optional fields as optional, as suggested in this question. Django/Bootstrap already styles fields as green/red after form submission, if a required field is missing, but my request is when the form is first rendered. Could be with *s or with "(optional)" or whatever. What's the best way to do it? -

CSRF verification Failed in Firebase and Django integration
I am trying to integrate django and DRF with firebase real-time database and while creating a post request I ran into a CSRF verification error. CSRF verification failed. Request aborted. Some solutions I found online said that I should use render but I am actually using Django Rest Framework and would like to use something that works with JsonResponse and Serializers. Here's a test code. def post(self, request): """Function to handle post requests Args: request (_type_): _description_ """ # Get the data to be posted from the request name = request.POST.get('name') age = request.POST.get('age') location = request.POST.get('location') # Set the reference to the database ref = db.reference('/user1') # Push the data to the database ref.push({ 'Name': name, 'Age': age, 'Location': location }) Let me know if I should share how I am creating my firebase client, although I don't think that would be necessary. In conclusion, I would like to find a way to add a csrf_token to a post request method in Django and DRF. Another solution I saw used csrf_exempt but I don't want to use that either as that is not ideal. I do plan on taking this to production at some point so do recommend solutions … -

Docker-Compose Network Issue on Ubuntu 22.04 LTS
I've been developing my python application using Django with PostgreSQL and Nginx and Docker, driven by Docker-Compose on my Macbook M1. And recently, decided to deploy it on the remote server, which has Ubuntu 22.04 LTS, but encountered really weird issue. My web application says, that it cannot resolve host postgresql (service at docker-compose file, which you can find down below), however, it works fine on my machine, can it be related to the Docker? It might be because I installed imcompatible versions of Docker and Docker-compose on this remote server or apparently used wrong commands, but not really sure about that, as I haven't gained enough experience of working with Ubuntu yet.

How to integrate Fast API and Django
I wanna to write e-commerce website on django.

I am working on a form which has a select dropdown that requires an optgroup and select options… Optgroups are Regions (Asia, Europe etc) and options are countries belonging to the countries… I have developed a Form for this and applied choicefield and has written the logic inside the form itself… and then applied the HTML using FormHelper Layout so that I can just pass {% crispy form %} in the template… For some reason I cannot figure out, the data in the select option does not appear… I’d appreciate if you could help me debug the problem… Please note, there is no error message, just that when i go to webpage, the data in the dropdown isnt there… Models.py class CountryRegion(models.Model): id = models.AutoField(primary_key=True, editable=False) country_name = models.CharField(max_length=50, unique=True, verbose_name='Segment') region_name = models.CharField(max_length=50, verbose_name='Industry') class Meta: verbose_name_plural = 'RegionCountry' def __str__(self): return self.country_name + '-' + self.region_name Forms.py from django import forms from crispy_forms.helper import FormHelper from crispy_forms.layout import Submit, Layout, Row, Column, HTML from crispy_forms.bootstrap import FormActions from django.contrib.auth.models import User from django.forms import ModelForm from .models import Portfolio, Project, SegmentIndustry, CountryRegion class ProjectForm(forms.ModelForm): fk_project_location = forms.ChoiceField(choices=[]) def __init__(self, *args, **kwargs): super(ProjectForm, self).__init__(*args, **kwargs) region_list = CountryRegion.objects.values_list( "region_name", … -

How to pass text argument to custom widget in django form?
I'd like to display a dynamic text value in a custom widget. It will more or less be a bootstrap input group with some dynamic text in a input-group-append element. I'm having difficulty understanding how I can pass this through to the template, as when I define the field in the Form class, I can't seem to reference arguments from the Form constructor. I'm inexperienced with both python and django so its very likely I'm missing some foundational python knowledge that's causing my confusion. If I do this, the widget renders partially ok (There is an automatic label "Site prefix" rendered that I don't want but that seems like a different problem) class SiteNameForm(forms.Form): site_prefix = forms.CharField(widget=SiteNameInputWidget(prefix_for='T E S T'), label=None) And create the form like so form = SiteNameForm() However, I need to pass in a dynamic value, so I tried class SiteNameForm(forms.Form): def __init__(self, prefix_for=None, *args, **kwargs): self.prefix_for = prefix_for self.site_prefix = forms.CharField(widget=SiteNameInputWidget(prefix_for=self.prefix_for)) super().__init__(self, args, kwargs) While creating the form form = SiteNameForm(prefix_for='TEST') But when I do that, nothing is rendered at all, not even the automatic label that I didn't want. The template specified as template_name <div class="row"> <div class="input-group mb-3"> <div class="input-group-prepend"> <span class="input-group-text">https://</span> </div> <input … -
How can I test render methods for django template Node?
I have written a django template Node for templatetag. How can I test render method (render method only) for Node?
