Is it possible to authenticate the default and a custom User model parallelly?
Our project deems necessary the need for a custom PublicUser model. We need to preserve the default authentication for the /admin/ endpoint as well. In contrast, we'll have a public /public/login/ endpoint wherein we'd like to implement the aforementioned custom PublicUser model that we can we with the default authenticate(), login(), and logout functions. So, chronologically, the default User model must still work with the /admin/ endpoint; the PublicUser model must work with the /public/login/ endpoint. And, both the models must work with the default authentication(), login(), and logout() functions so as to manage public sessions with ease. Note: We do not want to change the default authentication model for the /admin/ endpoint. It must be separate. AUTH_USER_MODEL = "users.PublicUser" # Refrain from doing this Any suggestions on how to go about this? Thanks! -
Example for customizing the ignored pattern list in Django's collectstatic
Like other questions here, I want to ignore my .scss files when running collectstatic. But because I'm using Heroku, which runs a collectstatic automatically, I would rather customize collectstatic's ignore pattern list rather than change the management command. Django 2.2 provides a way to do this, as documented below: The default ignored pattern list, ['CVS', '.', '~'], can be customized in a more persistent way than providing the --ignore command option at each collectstatic invocation. Provide a custom AppConfig class, override the ignore_patterns attribute of this class and replace 'django.contrib.staticfiles' with that class path in your INSTALLED_APPS setting: from django.contrib.staticfiles.apps import StaticFilesConfig class MyStaticFilesConfig(StaticFilesConfig): ignore_patterns = [...] # your custom ignore list My problem is that, this being my first Django project, I don't quite know how to provide a custom AppConfig class (and diving into the AppConfig docs hasn't helped). I mean, should I add this class to a whole new app or use an existing one? Is this class going to be in a apps.py file? If so, what should be the best app to do so? So I'm asking if anyone could provide me with an example of the best practice. For reference, right now my app … -
Django Prefetch Related
I have complicated prefetch_related in django, for execute query, database only need 0.06s for 200 rows in each prefetch_related attribute but for execute all response it's need 60s, I think when I want to call attribute in , django requires searching 200 data in the list of result How to solve it?

How to provide access of special information page to specific users
I am building website using django/python. This website include some webpages (say P1 and p2) in which p2 is form which can be accessed by p1 and link to p1 will be given to specific users via email and messages. I want to prevent other than specific users to go on p1 page of site. consider the situation I have given the link to some user x1 he uses the link and read p1 page and fill form on p2 page now link should expire AND generally URL https://www.website.com/home/p1 should not be directly accessible if entered in browsers for any user. that will prefectly make those pages safe from access of other people. This is quite complex situation how django authentication should be used for it? (Please note that my website does not have single link pointing towards p1 or p2 just the generated link will be way to access p1 and then p2 through p1 can we generate link like that?) -

Django REST framework reset password confirmation not working
I am building a user authentication backend with djano using rest_auth and allauth. This is my api app's urls.py urlpatterns = [ path('rest-auth/', include('rest_auth.urls')), path('rest-auth/registration/', include('rest_auth.registration.urls')), path("account/", include('allauth.urls')), ] after running server, I am going to rest-auth/password/reset, type in the email and post. an error occurs saying: NoReverseMatch at /api/v1/rest-auth/password/reset/ Reverse for 'password_reset_confirm' not found.

I found this SO question which helped: NoReverseMatch at /rest-auth/password/reset/ and after looking at the django REST framework official demo: https://django-rest-auth.readthedocs.io/en/latest/demo.html, I included other endpoints in my url.py as suggested: urlpatterns = [ # rest framework authentication: login/logout/signup etc ... path('rest-auth/', include('rest_auth.urls')), # url endpoint for registration path('rest-auth/registration/', include('rest_auth.registration.urls')), # url endpoint to confirm email for change of password path('password-reset/confirm', TemplateView.as_view(template_name="password_reset_confirm.html"), name="password-reset-confirm"), # url link to change password (sent via email) path('password-reset/confirm/<uidb64>/<token>/', TemplateView.as_view(template_name="password_reset_confirm.html"), name='password_reset_confirm'), # to handle different account emails (facebook, github, gmail, etc .. ) path("account/", include('allauth.urls')), ] where I also included my simple html landing page when resettinthe g password.

How to set ALLOWED_HOSTS Django setting in production when using Docker?
I always set my ALLOWED_HOSTS from an environment variable in Django. In my development .env I always set ALLOWED_HOSTS=.localhost,.127.0.0.1 and in production ALLOWED_HOSTS=mydomain.dom,my_ip_address Now I am currently getting acquainted with Docker, and the question is what is the value of the ALLOWED_HOSTS in production. Should it remain as localhost, since I understand localhost will refer to the host container or should I set it as my domain. I am using Nginx for reverse proxy to forward requests. -

Showing the uploaded csv file on Django template

Django runserver not running when importing another python file

Running manage.py shell with -c flag within docker-compose run
I want to run a script that runs Django code in my docker container. My initial plan was to run the following: docker-compose run web python manage.py -c "import django; print(django.__version__)" However, that isn't working: it prompts manage.py shell: error: unrecognized arguments. I guess it has to do with the fact that -c is a flag shared both by manage.py and by bash, or at least that's what I gathered from the docker-compose docs and Django's. If I run docker-compose run web bash, it prompts the shell, where I can do python manage.py shell -c "...". How can I do that in just one step? Any help is much appreciated. -

Effective ways of reusing python-request in function for internal api calls
I'm using python request lib for internal calls in our Django app. we have many helper functions for such internal calls. The problem with this approach is we are repeating the same function for different internal calls. Differences being request_url, request_data, request_response(tuple/list/dict). We are using the following function for internal calls, the same function is used for different calls based on the difference in input data, URL and response. for ex: get_data_from_service1, get_data_from_service2 etc def get_data_from_service(data): request_url = BASE_URL + "api/post/service/" request_data = rqt.get_service_request_translator(data) try: request_response = requests.post(url=request_url, data=request_data) except requests.exceptions.RequestException as ex: logger_excp.exception(str(ex)) return error_msg.UNABLE_TO_REACH_SERVICE if request_response.status_code == 200: models_data = request_response.json().get("data") total_count = request_response.json().get("total_count") return models_data, total_count elif request_response.status_code == 500: logger.error(request_response.text) return error_msg.PROBLEM_WITH_SERVICE else: logger.error(request_response.text) return error_msg.SOMETHING_WENT_WRONG please help with the following points. What would be an effective way of not repeating function everywhere should something like a base class be used? How to handle timeouts at global(base class/factory function?) and local functions? for ex: a base class/function having a timeout of say timeout=5 while local function having a timeout of timeout=2 or no timeout at all. how to change the error response of such functions. say for example if I want to raise an exception instead … -
