Django Forms ignoring USE_L10N configuration
It looks like my django application is not respecting the settings configuration USE_L10N=True In [1]: from django import forms In [2]: class SomeForm(forms.Form): ...: some_date = forms.DateField(required=False) ...: In [3]: form = SomeForm(data=dict(some_date='28/05/2020')); form.errors Out[3]: {'some_date': ['Enter a valid date.']} In [4]: from django.conf import settings In [5]: settings.USE_L10N Out[5]: True In [6]: import locale In [7]: locale.getlocale() Out[7]: ('pt_BR', 'UTF-8') In [8]: form = SomeForm(data=dict(some_date='05/28/2020')); form.errors Out[8]: {} If I use MM/DD/YYYY or YYYY/MM/DD it works. Shouldn't django be using this pt-BR format instead? What can be wrong? Thank you in advance! -

Django / Apache returns HTTP 500 Randomly
I have been dealing with a rather strange issue lately. My backend has httpd + mod wsgi + Django setup. I have a class-based view as follows: class ExtrasView(View): def get(self, request): path = settings.BASE_DIR + "/data.json" with open(path, encoding='utf-8') as f: data = json.loads(f.read()) return JsonResponse(data) The get request to the above view works perfectly 9 out of 10 times. However, randomly this view would give a response with status 500. Based on the apache log, it seems that the response body length is correct i.e. the length of data in the file. This is verified by apache access logs. Does anyone have an idea why this might be happening? I have checked the error logs and there's nothing in the errorlog. The error log does print tracebacks in case of exceptions or other syntax errors, just in this case it doesn't print anything so I'm clueless. Needless to say, the file being read is a static file that 100% exists. The data in the file is huge, it's length is about 30-40k characters. Would this cause an issue? If yes, then why does it work 9 out of 10 times? Any comments are welcome. -
Gunicorn not working on Amazon ec2 server
I am trying to deploy a django website on an aws ec2 instance (ubuntu 18.04) following this tutorial that is consistent with other online resources.

Where have I gone wrong? p.s: I had initially done sudo apt-get -

Django specify which database to use for module
In my Django project I have a couple of applications, one of them is email_lists and this application does a lot of data handling reading data from the Model Customers. In my production environment I have two databases: default and read-replica. I would like all queries in a particular module to be made against the replica-set database. I can do that if I explicitly tell the query to do so: def get_customers(self): if settings.ENV == 'production': customers = Customer.objects.using('read-replica').filter() else: customers = Customer.objects.filter() but this module has more than 100 queries to the Customer and other models. I also have queries to relations like: def get_value(self, customer): target_sessions = customer.sessions.filter(status='open') carts = Cart.objects.filter(session__in=target_sessions) the idea is that I want to avoid writing: if settings.ENV == 'production': instance = Model.objects.using('read-replica').filter() else: instance = Model.objects.filter() for every query. There are other places in my project that do need to read from default database so it can't be a global setting. I just need this module or file to read using the replica. Is this possible in Django, are there any shortcuts ? Thanks -
django-using same route in url path
I was working on a project and I am a beginner in Django. I am passing user.id from template to URL for tow things i.e one for profile update and one for a password reset. But it is going to only one URL whether I am clicking on profile update or password reset. I think the issue is I can not use the same routes in two URL paths. here is my url.py: urlpatterns = [ path('signup', views.signup, name='signup'), path('login', views.login, name='login'), path('logout', views.logout, name='logout'), path('<int:user_id>/', views.chgprofile, name='chgprofile'), path('<int:user_id>/', views.chgpassword, name='chgpassword'), ] here is my template code which shows the two buttons: <a class="btn btn-sm btn-outline-primary" href="{% url 'chgpassword' user.id %}">change password</a> <a class="btn btn-sm btn-outline-primary" href="{% url 'chgprofile' user.id %}">update profile</a> -
Django setting models.DateField() with a datetime object
I'm debugging some failing test after we recently upgraded from django 1.11 to 2.2, and i've noticed a behaviour that i havent been aware before. consider the following code from datetime import date, datetime, timedelta class User(models.Model): birthday = DateField() user = User.objects.create(birthday=date.today()) # setting the DateField object with datetime yesterday_datetime = datetime.now() - timedelta(days=1) user.birthday = yesterday_datetime user.save() user.refresh_from_db() print(user.birthday) # returns date.today() I've always assumed that when a DateField object has been populated with a datetime object, that the date aspect of the datetime object is taken and saved. It seems like this is not the case, and the field isnt updated / saved to the db. Is this a django 2+ behaviour or has this been the default for quite some time? Can anyone share their experience with this edge case? -
Django name magic in serializers.py file for HyperlinkedModelSerializer?
so I was trying to debug a problem where for a particular view using a HyperlinkedModelSerializer, one level of data was being returned as ints not urls. Ie, I was getting { "id": 4, "title": "asdf", "photos": [ 4 ], }, where I should have been getting { "id": 4, "title": "asdf", "photos": [ "http://localhost:8000/pics/4/" ], }, What was really weird, is the exact same viewset function works when I move it to the serializers.py file, but returns the wrong data when it lives in views.py. The function is as follows: class MemberMenuItemsViewSet(AuthModelViewSet): """ all items available from this maker (from all menus) """ serializer_class = MenuItemSerializer queryset = MenuItem.objects.all() def get_queryset(self): #def get(self, request, *args, **kwargs): member_id = self.kwargs.get('member_id') return MenuItem.objects.filter( menu__owner_id=member_id).order_by('-updated_at') I have solved my problem for now by moving this function to the serializers.py file and adjusting the call to it in urls.py ; but it is baffling why moving the function here instead of in views.py, should make any difference. I've tested it several times with consistent results, and my conclusion is there is some name magic going on? Or somewhere that I have not realized the serializers.py file is being pre-processed? Its no longer a … -
Connection refused while using MongoDB with Django

Django - prefetch_related GenericForeignKey results and sort them
I have the below structure, where content modules, which are subclassed from a common model, are attached to pages via a 'page module' model that references them via a GenericForeignKey: class SitePage(models.Model): title = models.CharField() # [etc..] class PageModule(models.Model): page = models.ForeignKey(SitePage, db_index=True, on_delete=models.CASCADE) module_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) module_id = models.PositiveIntegerField() module_object = GenericForeignKey("module_type", "module_id") class CommonModule(models.Model): published_time = models.DateTimeField() class SingleImage(CommonModule): title = models.CharField() # [etc..] class Article(CommonModule): title = models.CharField() # [etc..] At the moment, populating pages from this results in a LOT of SQL queries. I want to fetch all the module contents (i.e. all the SingleImage and Article instances) for a given page in the most database-efficient manner. I can't just do a straight prefetch_related because it "must be restricted to a homogeneous set of results", and I'm fetching multiple content types. I can get each module type individually: image_modules = PageModule.objects.filter(page=whatever_page, module_type=ContentType.objects.get_for_model(SingleImage)).prefetch_related('module_object_') article_modules = PageModule.objects.filter(page=whatever_page, module_type=ContentType.objects.get_for_model(Article)).prefetch_related('module_object') all_modules = image_modules | article_modules But I need to sort them: all_modules.order_by('module_object__published_time') and I can't because: "Field 'module_object' does not generate an automatic reverse relation and therefore cannot be used for reverse querying" ... and I don't think I can add the recommended GenericRelation field to all the content … -

Django adds square brackets and quotes to charfield input
recently I encountered a rather weird problem with my Django forms. I am currently working on my todo list project. Everything works fine, except that whenever I add a new task, its title seems to be saved in database with additional square brackets and quotes around it. It looks like one-element list, but it is a string. I kinda solved it by displaying the silced version of the string from the database, but it still shows for example while editing a task.
