Using Django with Firebase for a To-Do + Social App
Background: The Web/App im working on is a To-Do kind of app which has the features of user profile, to-do lists, reminders, events. The other imp feature is that users should be able to make friends(like social media) and also create group events. I already made a simple prototype (To-do web app) using Django but now I wanted to scale it using Firebase as database and many of its other services like Cloud functions/ notifications/auth etc.. From the things i read about Firebase, it can be used even as backend (with help of cloud funts) and also for hosting. Problem: Is it a good option to use Django as backend and firebase as database(NoSQL) for the type of project im doing keeping in mind that more focus is on the tasks and reminders and also allowing group events and friends list in user profile? I am also planning to scale the app to android once the web is done, So isnt it better to write the backend requests code on Firebase cloud functions and avoid using Django at all? (I also read that using a django like backend server is better for secuirty reasons) Need: I would be very happy … -

Django: Trying to catch ValidationErrors and return results as boolean
I don't understand why this try/except isn't working. I have a validation method that might raise a ValidationError (one of several). However, in another method that renames a schema, I want to catch all those errors in favor of one generic message. The validation method (edited for brevity): def validate_tenant_schema_name(tenant, value): if {some invalid condition in schema name}: raise ValidationError('Schema name may not be blank.') if {some other invalid condition in schema name}: raise ValidationError('Schema name may not begin or end with an underscore.') if {yet another invalid condition in schema name}: raise ValidationError('Schema name must have 2 to 30 characters.') return name My validation "wrapper" method: def is_valid_schema_name(name): try: _ = validate_tenant_schema_name(None, name) return True except ValidationError: # Debug got here return False # but didn't get here My schema_rename method: def schema_rename(tenant, new_schema_name): if schema_exists(new_schema_name): raise ValidationError("New schema name already exists") if not is_valid_schema_name(new_schema_name): raise ValidationError("Invalid string used for the schema name.") ...run the sql to rename the schema... tenant.save() When I stepped through it in debug, it got to the except in the is_valid method, but didn't get to the return False - as noted by the comments in the is_valid method. It just returned to the … -
Handling of django authentication with multiple apps
Cant find a solution to a simple problem from current SO questions. I have 2 apps in a django project. App1 is from the graph tutorial found here App2 will allow the users to list data from a DB in this case it will be branch names. If I try and access a page with @login_required decorator then the url route has /accounts/login/ added and I get the usual cant find error. Page not found (404) Request Method: GET Request URL: http://localhost:8000/accounts/login/?next=/calendar Using the URLconf defined in graph_project.urls, Django tried these URL patterns, in this order: [name='home'] about [name='about'] signin [name='signin'] signout [name='signout'] calendar [name='calendar'] callback [name='callback'] branches/ admin/ branches/ The current path, accounts/login/, didn't match any of these. If I am reading the django docs correctly then this is default and I can redirect the login path using the LOGIN_URL in the project settings. When I set that to the signin function created in the tutorial for App1 def sign_in(request): # Get the sign-in URL sign_in_url, state = get_sign_in_url() # Save the expected state so we can validate in the callback request.session['auth_state'] = state # Redirect to the Azure sign-in page return HttpResponseRedirect(sign_in_url) It will forever cycle the MS … -

Cannot access through model from the model that defines m2m field
I am trying to build a simple e-commerce website with django 2.2.4 .

Django allauth send email verification code instead of email verification link
I am using Django allauth as an API for a mobile application. Currently, when you register Django will send you an email containing a link which you have to go to in order to verify your email. But what if I want to make it so that Django send an email with a verification code which you then enter into the app? I know it seems kind of redundant but I think it will help streamline the user experience (since my platform will primarly have an app). Is this possible to do? -

Django - Cannot update the form
my template has three columns in one form where they work separately. If I give input for contact column and male column it will save in my database. So basically I want to update the male only as contacts,male and female inputs are present in same html form. I can update the contact but male or female inputs. They all are in same page.I want to make them working separately so I can update them. The problem is that when I give inputs for the it gets posted but not for male and female inputs.

How to resolve AWS Elastic Beanstalk Django health check problems
I've recently deployed my Django API backend to AWS EB to their Linux 2 system (exact platform name is Python 3.7 running on 64bit Amazon Linux 2). Almost everything is working as expected, but my application health status is Severe and after hours of debugging I've no idea why. The application's health check is being handled using the following endpoint (django-health-check module). url(r'^ht/', include('health_check.urls')) 100% of the requests have a status code of 200 but my overall health status is the following: |--------------------|----------------|---------------------------------------------------| | instance-id | status | cause | |--------------------|----------------|---------------------------------------------------| | Overall | Degraded | Impaired services on all instances. | | i-0eb89f... | Severe | Following services are not running: release. | |--------------------|----------------|---------------------------------------------------| The strangest thing is the fact that the message Following services are not running: release. is unique to the internet (seems like no one has had such problem before). The other weird thing are the contents of my /var/log/healthd/daemon.log file which are lines similar to W, [2020-07-21T09:00:01.209091 #3467] WARN -- : log file "/var/log/nginx/healthd/application.log.2020-07-21-09" does not exist where the time changes.
