Integrating paypal's subscription to Django app (with paypal button)
I am building my first Django (2.0.5) application. So far I've set a standard django user model having plus an email attribute and a slightly custom signup form for it. I want to add a subscription to the app. After some research, I end up that a simple way to do it might be using the paypal's buttons, specifically the subscription button modification. Having followed the instructions from the paypal website, I placed the form with the test button on the template and tested the sandbox account which seems to work properly. <form class="form-control" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" target="_top"> <input type="hidden" name="cmd" value="_s-xclick"> <input type="hidden" name="hosted_button_id" value="WDWEG7ZAJD4U2"> <input type="hidden" name="on0" value="Subscription options">{% trans 'Subscription options' %}<select class="form-control" name="os0"> <option value="Basic">{% trans 'Basic' %} : €X.00 EUR - {% trans 'monthly' %}</option> <option value="Premium">{% trans 'Premium' %} : €X.00 EUR - {% trans 'yearly' %}</option></select> <input type="hidden" name="currency_code" value="EUR"> <input type="image" src="https://www.sandbox.paypal.com/en_US/i/btn/btn_subscribeCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!"> <img alt="" border="0" src="https://www.sandbox.paypal.com/el_GR/i/scr/pixel.gif" width="1" height="1"> </form> It seems that after the test payment is successful, paypal redirects to the specified url and the process ends there. I would like to proceed somehow like getting a feedback from paypal regarding ... -

(custom user) createsuperuser TypeError: hasattr(): attribute name must be string
I've created a new Django project and the first thing I did was create a custom user with the help of Django docs: https://docs.djangoproject.com/en/2.0/topics/auth/customizing/ After I wrote all the code for a custom user, and after I did makemigrations and migrate for the first time in this Django project, I tried to create a superuser while my virtual env is active by writing: python manage.py createsuperuser But it gave me this error: TypeError: hasattr(): attribute name must be string I wrote all the custom user code in an app called accounts.

Deconfiguration of the DJANGO_SETTINGS_MODULE variable (irreparable)
The fact is that I have a VPS in Digital Ocean with Ubuntu 18.04. I installed everything necessary starting with the typical apt update and upgrade, then pip, virtualenvwrapper, django and postgresql, started with runserver and tried in the browser the django and django-admin test page, all perfect for a few days. After a few days, I upgraded my system again with apt update and upgrade, and the django application stopped working, with the error "You must either define the variable DJANGO_SETTINGS_MODULE variable or call settings.configure () before accessing settings. " I have tried many things without finding the solution; I have reinstalled virtualenvwraper, django, virtual environments and project, but it still does not work as before. I have also tried to assign the variable manually with export DJANGO_SETTINGS_MODULE = settings and it says that the module can not be found. Any idea of what has happened to my system? I would like to try all the possibilities before deleting the droplet and reinstalling everything. -

Form validation: "That choice is not one of the available choices."
One of my models has a foreign key field. This field is displayed, as expected, as a drop-down (Select widget). The POSTed value for that field is a string, although the related model's ID has a default type primary key (integer): Therefore, form validation fails while cleaning the data with: Select a valid choice. That choice is not one of the available choices. I have no custom form definition or validation at all. Why is the foreign key provided via select widget in form not converted to the right type? -

DRF nested routers could not resolve URL for hyperlinked relationship
I am trying to use drf-nested-routers to create a nested url pattern like the following: /projects/{project_pk}/join_request/{pk} With my current setup, I am able to navigate to /projects successfully, and see the list of hyperlinked join_requests: [ { "url": "http://127.0.0.1:8000/projects/1/", "join_requests": [ "http://127.0.0.1:8000/projects/1/join_requests/1/", "http://127.0.0.1:8000/projects/1/join_requests/2/" ], "name": "Sample Project" } ] However, when I click through to a join_request, I get the following error: ImproperlyConfigured at /projects/1/join_requests/1/ Could not resolve URL for hyperlinked relationship using view name "projectjoinrequest-detail".

Difference between configuring database on zappa app & regular django app
Is there any difference configuring a zappa app & a regular django app? I am following this tutorial on setting up a zappa app and under "Configure the database" it links to paid tutorials - and I can't find much info via searching google. So is it any different than just changing my DATABASES in my settings, installing psycopg2 and migrating the changes? Or does zappa require something different/more? -
Q object filtering with multiple conditions failing
I am trying to apply multiple conditions to my filter. The model looks like this class modelChat(models.Model): source = models.ForeignKey(modelEmployer,related_name = 'rsource',on_delete=models.CASCADE,null=True,default=None,blank=True) job = models.ForeignKey(modelJob,on_delete=models.CASCADE,null=True,default=None,blank=True) destination = models.ForeignKey(modelEmployer,related_name = 'rdestination',on_delete=models.CASCADE,null=True,default=None,blank=True) Initially I am trying to obtain an instance of chat that involves 2 parties based on a job. At one point source can be a destination and sometimes the destination can be the source. This is what my query looks like querySet = modelChat.objects.filter( (Q(source=modelEmployerSourceInstance) | Q(destination=modelEmployerSourceInstance)) & (Q(destination=modelEmployerDestinationInstance) | Q(destination=modelEmployerDestinationInstance)) & Q(job_id=job_id) ) The job id is correct and I know there is only one item in the DB however this query alway returns back an empty item. Any suggestions why this is wrong and how I can fix it ? -
Removing case sensitivity from Email in Django login form
Before anyone marks it as duplicate, I've searched everywhere and didn't find. I've created a custom UserModel and used Email as main authenticating id instead of username.

React development server serves django backend, but django cannot receive pages from react on same server
So I am running a react django server based on a tutorial here: http://v1k45.com/blog/modern-django-part-1-setting-up-django-and-react/ My django server is running on port 80, which I have portforwarded, and my react development server is running port 3000. When I access my website on localhost(port 80), I am able to render the react default homepage. However, when I access the website externally, I am able to access the django server at port 80, but the react portion does not render, giving me a blank screen. Would be grateful to someone who could help me with this problem, just starting web development in django and react in general and it's giving me a lot of bumps. Thanks! -
