Check if the /profile page is redirecting to /login page and add a warning message
Just an FYI that I'm currently at day 4 learning Django (Thanks to Corey Schafer's amazing playlist) I just completed creating the Login-logout system and was trying to add a warning message when a user tries to access the /profile without being logged in which successfully redirects to the /login page . And since the @login_required decorator doesn't have that built-in, I was trying to think of a logic which would check, if the /profile page redirects to the /login page > add a warning message. (I tried creating my own decorator but the messages.warning fxn would require a user request which would throw an error) Kinda like this noob-ey code I tried : @login_required def profile(request): if LOGIN_URL == 'login': messages.warning(request, 'You need to login in order to access this page.') return render(request, 'users/profile.html') -
Django Rest pass variable not in model for logic in overridden save method
In DRF how can I pass for example a boolean which isn't in my model from ModelViewSet so it can be used in a overridden save method for some logic? I know with a model instance you can just assign it, but I'm unsure if this is possible from ModelViewSet or goes against the general flow of DRF. -

Django views confusion, two views show same content
I have a python django application. I had a view, which I duplicated and changed slightly to create a second view.

django: set default locale for language?
I'm building a multilanguage site using modeltranslate, I can switch between languages no problem. The problem comes with 'en' always being interpreted as 'en-us' which messes up the dates everywhere. It's a European site, I want 'en' to be interpreted as international English, or en-gb at least. I've looked all over but can't see a way to do this. Is there any way to set a default locale for a language in Django? Do I need to set language to en-GB and have en-gb in the url? I really don't want to have to do a lot of coding on every template just to override the US date formatting .... LANGUAGE_CODE = 'en-GB' LANGUAGES = ( ('es', _('Spanish')), ('ca', _('Catalan')), ('en', _('English')), ('fr', _('French')), ) Thanks in advance for your help. -

Dynamic choices in model CharField choices
This document shows an example of how to declare a model CharField with choices here class Student(models.Model): FRESHMAN = 'FR' SOPHOMORE = 'SO' JUNIOR = 'JR' SENIOR = 'SR' GRADUATE = 'GR' YEAR_IN_SCHOOL_CHOICES = [ (FRESHMAN, 'Freshman'), (SOPHOMORE, 'Sophomore'), (JUNIOR, 'Junior'), (SENIOR, 'Senior'), (GRADUATE, 'Graduate'), ] year_in_school = models.CharField( max_length=2, choices=YEAR_IN_SCHOOL_CHOICES, default=FRESHMAN, ) The list YEAR_IN_SCHOOL_CHOICES is part of the class Student. Does it mean this list is stored somewhere in the database? If so, can it be accessed and modified during runtime? Suppose I need to make this list dynamic depending on another model class. For eg: class Edu_Level(models.Model) level = models.CharField(max_length = 200) Each time my app creates a new Edu_Level, I want to add that level to the choice list in the other Student model. Assuming that they are both in the same app, is this possible? Thanks. -

Changing the Default Frontend for Django_filters
I was following through the Dennis Ivy Youtube Django Tutorials and came across a question (https://www.youtube.com/watch?v=G-Rct7Na0UQ&list=PL-51WBLyFTg2vW-_6XBoUpE7vpmoR3ztO&index=13) So the views.py is like this: def customer(request, pk_customer): customer = Customer.objects.get(id=pk_customer) orders = customer.order_set.all() order_count = orders.count() myFilter = OrderFilter(request.GET, queryset=orders) orders = myFilter.qs context = {'customer': customer, 'orders':orders, 'order_count':order_count, 'myFilter':myFilter} return render(request, 'accounts/customer.html', context) and the filters.py is like this: import django_filters from django_filters import DateFilter, CharFilter from .models import * class OrderFilter(django_filters.FilterSet): start_date = DateFilter(field_name='date_created', lookup_expr='gte') end_date = DateFilter(field_name='date_created', lookup_expr='lte') class Meta: model = Order fields = "__all__" exclude = ['customer', 'products'] and lastly the template that shows this part has this line of html code: ... <div class="card card-body"> <form method="get"> {{myFilter.form}} <button class="btn btn-primary" type="submit">Search</button> </form> </div> </div> but what I don't really get is that in the frontend: I don't want the "Date created is greater than or equal to" or "Date created is less than or equal to" to show it like that but maybe change it to a different wording, something like for example just GTE or LTE or stuff like that I couldn't seem to find a way, and is there a way?? -
