What are the default namespaces for django authentication URLs?
I changed my app's urls.py to have a namespace app_name = 'somename'. And then did these, Changed reverse('url-name') to reverse('somename:url-name'). Changed {% url 'url-name' %} to {% url 'somename:url-name' %}. Changed a {% if request.resolver_match.url_name == "url-name" %} to {% if request.resolver_match.url_name == "somename:url-name" %}. For accounts app, I only have two custom views for login and signup. So a reverse like reverse('accounts:login') is working but reverse('accounts:password_reset') (part of default django auth) is not working. Here is what I tried, Replaced reverse('accounts:password_reset') with reverse('auth:password_reset'). Replaced reverse('accounts:password_reset') with reverse('password_reset'). Solution 1 did not work. Solution 2 is working. I also tried changing path('accounts/', include('django.contrib.auth.urls')) in my project's urls.py to path('accounts/', include('django.contrib.auth.urls', namespace='auth')) and path('accounts/', include('django.contrib.auth.urls, namespace='accounts')). Neither worked. project/urls.py urlpatterns = [ path('', include('core.urls')), path('admin/', admin.site.urls), path('accounts/', include('accounts.urls')), path('accounts/', include('django.contrib.auth.urls')), path('books/', include('library.urls')) ] accounts/urls.py app_name = 'accounts' urlpatterns = [ path('signup/', views.CustomSignup.as_view(), name='signup'), path('login/', views.CustomLogin.as_view(), name='login'), ] Why namespacing password_reset with accounts and auth fail? Is there a documentation page that has default namespaces that can be used? -
Uploading Images from Ckeditor to Google Drive
I am using Django Google Drive Storage from this repo to store and serve my media files in Django.

How do I tell python to use a variable with the name of the value of another variable?
In my code I define multiple variables with names that are equal to the value I get when calling field.name, so I though that I could pass them in with this for loop: if formReminders.is_valid(): needsImprovement = formReminders.cleaned_data["needsImprovement"] hasFallacies = formReminders.cleaned_data["hasFallacies"] hasEmotionalDeficiency = formReminders.cleaned_data["hasEmotionalDeficiency"] isNecessaryToObtain = formReminders.cleaned_data["isNecessaryToObtain"] doesAReallyCauseB = formReminders.cleaned_data["doesAReallyCauseB"] areAllStepsPresent = formReminders.cleaned_data["areAllStepsPresent"] isCauseSufficient = formReminders.cleaned_data["isCauseSufficient"] areAllClausesIdentified = formReminders.cleaned_data["areAllClausesIdentified"] isCausalityCertain = formReminders.cleaned_data["isCausalityCertain"] languageIsEnglish = formReminders.cleaned_data["languageIsEnglish"] isTautologyPresent = formReminders.cleaned_data["isTautologyPresent"] for field in ImprovementAbstraction._meta.fields: need.field.name = field.name so if field.name is equal to "needsImprovement" I want to use the variable needsImprovement, how can I achieve this in python? -
Dynamic django serializer
im learning to use DRF and i realize there's alot of code that is being repeated within the serializer , and im wondering if im doing the right thing. Here's an example. I have 2 main models : The 2 main models class SalesProject(models.Model): sales_project_name = models.CharField(max_length=100) customer_information = models.ManyToManyField('CustomerInformation') sales_department = models.ForeignKey('SalesDepartment', on_delete=models.CASCADE) #bunch of isolated fields not stated here class Ticket(models.Model): title = models.CharField(max_length=255) customerInformation = models.ForeignKey('CustomerInformation', null=True , blank = True, on_delete = models.CASCADE) salesProject = models.ForeignKey('SalesProject', null=True , blank = True, on_delete = models.CASCADE) #bunch of isolated fields not stated here These models have varying depth which i wish to access in different scenarios. For example , When wanting to access the detail page for Ticket i would wish to exclude certain infomation i would otherwise get from using a general serializer that i defined for SalesProject and CustomerInfomation. This would then lead me to my issue , which is to rewrite a specialized foreign key serializer for SalesProject , of which all i am doing is just excluding the fields from the main general serializer for SalesProject. As illustrated here : class SalesProjectDetailSerializer(serializers.ModelSerializer): #general serializer which contains all fields and has depth of 2. This … -
DRF Serializer Prevent Instance Update if Foreign Keys aren't Updated Properly
I have a model serializer for a model with some foreign keys. My understanding is that to add objects to the foreign fields, you first save your instance and then add the fields. However, if I happen to have an error in the data I am adding to the foreign keys, this will save the updated instance but not the foreign key data (obviously, as it has an error). But if the foreign key doesn't save, I don't want the updated instance to save either. Do I have to verify the proper data before calling serializer.save()? Example: In the code below, I have a MatchModel that contains foreign keys of MatchResultVote and MatchTeams. If a match is started, I send a put request with updated data that changes isAvailable to false, isStarted to true and adds a MatchTeam The code below works fine, but if I end up accidentally passing bad data for the MatchTeam I want to add, it will still update the instance (i.e. changing isAvailable to false and isStarted to true) even though I don't want this to happen unless the MatchTeam data is also valid I'm thinking I am probably supposed to validate the MatchTeam data … -

I need to host multiple sites with subdomains all pointing to the same windows10 server. virtual hosts for different sub-domains points to different WSGI files. Venv activation is added in wsgi file. The issue happening is first Django settings file which is invoked is applied to all sub-domains. eg. company1.example.com -> /company1_wsgi.py -> company1_settings.py company2.example.com -> /company2_wsgi.py -> company2_settings.py Now, company1_settings is applied for both company1.example.com and company2.example.com. I see right WSGI files are called based on the sub-domain but for some reason os.environ['DJANGO_SETTINGS_MODULE'] is not being updated dynamically based on the subdomains and always uses the first value wsgi file python_home= 'E:/app/demo/env' activate_this = 'E:/app/demo/env/Scripts/activate_this.py' exec(open(activate_this).read(),dict(__file__=activate_this)) import os import sys from django.core.wsgi import get_wsgi_application import site # Add the site-packages of the chosen virtualenv to work with site.addsitedir('E:/app/demo/env/Lib/site-packages') # Add the app's directory to the PYTHONPATH sys.path.append('E:/app/demo/crm') sys.path.append('E:/app/demo/crm/appointment_scheduler') os.environ['DJANGO_SETTINGS_MODULE'] = 'appointment_scheduler.settings.preprod' application = get_wsgi_application() <VirtualHost *:443> ServerName demo.crmbaylyn.com WSGIScriptAlias / "E:/app/demo/crm/appointment_scheduler/wsgi_win.py" WSGIPassAuthorization On WSGIScriptReloading On <Directory "E:/app/demo/crm/appointment_scheduler"> <Files wsgi.py> Order deny,allow Allow from all Require all granted </Files> Order allow,deny Allow from all Require all granted </Directory> Alias /static "E:/app/demo/crm/static" <Directory "E:/app/demo/crm/static"> Require all granted </Directory> SSLEngine on SSLCertificateFile "C:/Apache24/conf/crmbaylyn.cert" SSLCertificateKeyFile "C:/Apache24/conf/crmbaylyn.key" </VirtualHost> <VirtualHost *:80> RewriteEngine On RewriteCond %{HTTP:X-Forwarded-Proto} … -

Django ORM extract weekday as string from queryset
What I'm trying to do is annotate a queryset with the weekday strings ("monday", "tuesday" etc). I understand how to get the int values: queryset = queryset.annotate( weekday_int=ExtractWeekDay("date"), ) But I'm having trouble getting the string values themselves. I've tried using an ExpressionWrapper, but F objects don't seem to play well with Date objects. I'm using postgres as my underlying database but can't find a related lookup_name for the generic Extract. -
