Replace or extend User model in Django 3 in custom model
I am trying to replace User model or Extend (not sure what indeed), in Django for being able to use authenticate() and decorators as @login_required and/or permissions in my methods. Why I am doing this? may you ask. Is because the Django project is not following the best practices or orthodox ways of the framework. Before me was another developer taking this kind of desicions. The project is in an advanced stage. Ok, my model is this (only this no Meta or anything more in this class): class UsuarioDiplomado(models.Model): nombres = models.CharField(max_length=50) apellidos = models.CharField(max_length=50) telefono = models.CharField(max_length=20) celular = models.CharField(max_length=20) correo = models.CharField(max_length=70) fecha_nacimiento = models.DateField() rol = models.ForeignKey("core.Rol", on_delete=models.PROTECT) activo = models.BooleanField(default=True) eliminado = models.BooleanField(default=False) password = models.CharField(max_length=20, default='123') hashusuario = models.CharField(max_length=100, default='') sucursal = models.ForeignKey("core.Sucursal", on_delete=models.PROTECT, default=1) this is the class that I want to use as extension of User class specifically the fields correo (email), and password in the settings.py I setup AUTH_USER_MODEL = 'colposcopia.UsuarioDiplomado', but as expected not working because lacks of the REQUIRED_FIELDS AttributeError: type object 'UsuarioDiplomado' has no attribute 'REQUIRED_FIELDS' I am not sure how can achive this? or what I need to do this. Can you shine some light please? -
Javascript Date unnecessarily adjusts for timezone
I am storing a date as a django DateField in my database. It simply looks like "2020-06-25" in the database. This string is returned from my api, and passed into a javascript "Date" as such: date = new Date(due_date) logging this date results in: Wed Jun 24 2020 17:00:00 GMT-0700 (Pacific Daylight Time) I don't care about the time, only the date. How do I get javascript Date to ignore the time, and not adjust for the difference in timezone between the DB and the local user? If a user sets the due date for a project in one timezone, I want every person to see the same due date. -

Django day and time picker
I'm trying to build my first website with django,I've accomplished user registration and login so far but now I'm stuck: I want to show to the users a weekly calendar where they can pick a day and book a gym class. I tried to handle every week day like a form field but it didn't work. Any advice on how I should tackle this? I'm looking for something like an explanation/a tutorial and would avoid a github project, if possible. Thank you! -
Cannot modify/override templates for django-allauth and django-comments-xtd
I have a Django project using Wagtail CMS. I'm using django-allauth for user accounts and django-comments-xtd for handling comments on the blog. I want to modify the templates for both of these apps. I've followed directions for doing so from their respective documentation, tutorials, and answers here on SO, but nothing I've tried works. (For reference, these SO answers have not helped.): override templates in django-allauth How to override template in django-allauth? Unable to override django-allauth templates What I've done is copied the templates I wanted to modify from site-packages/allauth/templates/account and site-packages/django_comments_xtd/templates/comments and into my project's templates directory (project/mysite/templates/account and project/mysite/templates/comments, respectively). However, when I modify the copied templates in my project's templates directory, the changes are not reflected. For fun, if I delete the templates in the site packages directory, then I get an error saying the templates do not exist. What's strange is that the first place Django looks for the templates is in my project's templates directory (and they are there), yet I get the error. Also, if I modify the templates under site packages directory, the changes ARE reflected, but I know this is bad practice because if I update these packages, my changes will be … -
Why is Django adding an extra character to the table name of a legacy database?
I am following this_site for onboarding a legacy database. Though, irregardless of the method used Django is adding an extra character (an s) to the only table within a legacy sqlite database (table: Dogs).

How to convert django.request logger time to UTC?

Using custom user model in Django always return anonymous user in template
I have created a custom user model since I need three information( email, institute id, password) to login to the system.

Django 3: browser doesn't display the content of a variable
I started learning Django 3 from a book. I have the following code: views.py: from django.views.generic import TemplateView class HomepageView(TemplateView): template_name = 'index.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['my_statement'] = 'Nice to see you!' return context index.html <h1>Greetings</h1> <p>Hello, world!</p> <p>{{ my_statement }}</p> The browsers (Opera and Firefox) will display fine the first 2 lines but nothing for the third in the index.html (so urls.py and settings.py should be correct?) Inspecting the page source I see for the third line the opening and closing paragraph tags with nothing in between. If I write abc or whatever before or after the {{ }}, that abc text gets displayed. I have even copy/pasted the code from the book authors, and no change. I'm sure I'm missing something obvious, but what? -
Django Pagination for Component

Need help designing a permissions system in Django and DRF
I'm trying to design a seemingly simple permissions system in Django and DRF. Right now, I have a user model, User, a custom group model, CustomGroup, an article model, Article, and finally a source model, Source. Just for reference, I'm using Django Rest Framework and Django Guardian. The article model contains a field source. I'd like a system built such that when a user makes a query request for articles, depending on their assigned custom group, return articles that omit articles that belong to a specific source. What I was thinking of implementing was something along the lines of class Source(models.Model): name = models.CharField(max_length=255) class Article: sources = models.ManyToManyField(Source) ... class Meta: permissions = ( 'can_view_source_1', 'Can View Source 1', 'can_view_source_2', 'Can View Source 2', ... 'can_view_source_n', 'Can View Source n' ) From there I can then assign these specific permissions to my custom group model. So, when a user makes a request for a queryset containing n sources, I can then iterate over all the sources by name and check if the user's custom group has permission to view that group. Something like (pseudocode warning!) the code below in my view or serializer. for source in sources_from_queryset: if not … -
