Django admin action with intermediate page processes only first 100 of selection

Fail to send email, but no error and exception
I am working on sending an activation email after the user registers an account. Everything works fine in the console. However, when I change to smtp Email backend, the program will stuck at send_mail() and then the program will refresh itself and send back "the username is taken". Finally, no email has been sent.

How to use authentication in Django application
In my Django application I have a PetOwner model with the following fields: first_name, last_name, email, phone_number, address. I want to create an authentication system now for my users which for now is a PetOwner. I was thinking I should extend from django.contrib.auth.models or more specifically, from django.contrib.auth.models import User I was planning on having a OneToOneField in my PetOwner model to reference the User. Something like the following... user = models.OneToOneField(User, on_delete=models.CASCADE) I'm not sure if this makes sense to do though. Also, I do not want my PetOwner to have access to admin privileges. I'm use to other frameworks like Flask or NodeJS where I would have to hash the password and have a hashed_password saved in a user document or row depending if I'm using sql or nosql. I want to basically make sure that when I am referring to a user I am referring to a PetOwner. -

Creating a survey with Django
I am trying to implement a survey in Django and have run into a couple of issues. The survey has two questions and the answer choices are supposed to be represented with radio buttons (the user can only select one choice for their answer). The issues I ran into: I am not able to show only the answer choices that belong to a specific question. For some reason I am getting all answer choices below each question. I have tried editing my models to link specific choices to a question, but still the same issue. 2)After the user clicks "Submit" they are not being directed back to the survey index page nor are their answers saved in the database. Here is what I have so far for my models: User = settings.AUTH_USER_MODEL class Questionnaire(models.Model): questionnaire_name = models.CharField(max_length=255) questionnaire_text = models.CharField(max_length=200) def get_absolute_url(self): return reverse('questionnaire-detail', args=[str(self.id)]) def __str__(self): return self.questionnaire_name class Question_Prompt(models.Model): prompt = models.CharField(max_length=200) questionnaire = models.ForeignKey(Questionnaire, on_delete=models.CASCADE, related_name='prompts') def __str__(self): return self.prompt class AnswerOption(models.Model): q_prompt = models.ForeignKey(Question_Prompt, on_delete=models.CASCADE, related_name='answers') questionnaire = models.ForeignKey(Questionnaire, on_delete=models.CASCADE, related_name='responses', default='') answer_text = models.CharField(max_length=200) def __str__(self): return self.answer_text class UserAnswer(models.Model): user = models.ForeignKey(User, on_delete = models.CASCADE) questionnaire_taken = models.ForeignKey(Questionnaire, on_delete = models.CASCADE) questionnaire_date = models.DateTimeField(auto_now_add=True) … -
Django view URL after deployment with Gunicorn
I have a Django backend and a React frontend that have been working perfectly before deployment. I ran: nohup python manage.py runserver my_server_ip:8000 & In this case, the view can be called by React with: my_server_ip:8000/app1/view1 After that, I deployed Django with Gunicorn and React with Nginx, Nginx config: server { listen 80; root /path_to_react_build_folder; server_name my_server_ip; index index.html; location = /favicon.ico { access_log off; log_not_found off;} location / { proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } Gunicorn.socket [Unit] Description=gunicorn socket [Socket] ListenStream=/run/gunicorn.sock [Install] WantedBy=sockets.target Gunicorn.service [Unit] Description=gunicorn daemon Requires=gunicorn.socket After=network.target [Service] User=my_username Group=www-data WorkingDirectory=/home/my_username/django_project_root ExecStart=/home/my_username/python_virtualenv/bin/gunicorn --access-logfile - --workers 3 --bind unix:/run/gunicorn.sock django_project_root.wsgi:application [Install] WantedBy=multi-user.target Connection was okay as I typed my_server_ip in browser (i.e. default to index.html set in Nginx config). All static things like background color and banner displayed normally but I couldn't get the result from API call. Browser console showed: GET http://my_server_ip:8000/app1/view1 net::ERR_EMPTY_RESPONSE How can I let React access Django's view in this case? -

Ajax calls not calling on a PWA
I just covert a django project to a pwa using django_pwa. Before hand, the project worked perfectly. Part of the project, I am making GET and POST requet using ajax.

How to easily extract request.POST data after Django form submission?
My request.POST data looks like this after my Django form submission: <QueryDict: {'form-0-country': ['19389'], 'form-0-city': ['Montreal'], 'form-0-eid': ['450'], 'form-0-company': ['Nestle'], 'form-0-dept': ['HR'], 'form-1-country': ['19390'], 'form-1-city': ['Toronto'], 'form-1-eid': ['432'], 'form-1-company': ['Nestle'], 'form-1-dept': ['Finance']}> These are values of two forms contained in two different rows on the webpage. The values from these two rows are printed sequentially in the request.POST. Is there a way to get this data printed in the backend in a simpler way so that I don't have to loop through all this data to extract the specific fields contained in it? For eg. something like this: <QueryDict: {'form-0-country': ['19389','19390'], 'form-0-city': ['Montreal','Toronto'], 'form-0-eid': ['450'], 'form-0-company': ['Nestle','Nestle'], 'form-0-dept': ['HR','Finance']> so that I can easily loop through the value (lists) in the dict above. instead of: <QueryDict: {'form-0-country': ['19389'], 'form-0-city': ['Montreal'], 'form-0-eid': ['450'], 'form-0-company': ['Nestle'], 'form-0-dept': ['HR'], 'form-1-country': ['19390'], 'form-1-city': ['Toronto'], 'form-1-eid': ['432'], 'form-1-company': ['Nestle'], 'form-1-dept': ['Finance']}> -
django permission based on AD group membership
I'm trying to grant access to specific URLs and menu links in base.html file based on AD groups an authenticated users belong to. The AD instance is fairly large but it also includes deeply-nested AD groups, so, quering the AD server for every HTTP request is an expensive one. A solution I'm think of at the moment is to write a custom middleware that queries the AD server the first time a user access the application, I query the AD server one time, get all the access levels they should have and store this information in a session, then, when they make another request, I check the session values first if I already set permissions for that specific user, this should avoid querying the AD server everytime. Given this criteria, is there any native django authorization classes/technique that is able to handle this sort of access privilege? -

Paginating Django View with Foreign Key Data
I'm trying to build a simple Django gallery that allows photos to be added to an album. Everything thus far is working fine (upload photo, add to album, paginated all photos listing, photo details/display pages, etc), until I try to display the 'album' pages.

Django dynamic url parameters
I'm trying to make an example for a product page where people can put designs on their product's. I'm using django and try to make my "designer" page behave differently on the type of product selected. I want to have it behave like www.mysite.com/designer/foo where foo is the name of the product I have gotten to make it work like www.mysite.com/designer?product=foo but i like the simplicity of the first url more and i can't imagine that wouldn't be possible. urlpatterns = [ path('', overview, name='overview'), path('designer/', designer, name='designer'), path('administration/', administration, name='administration'), path('admin/', admin.site.urls), ] my url patterns are like this, i've tried fiddling around with some examples using regex behind the "/" after designer. but i can't get it to work, the server keeps trowing Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/designer/exampleA I'm afraid i don't know where to start looking and how to properly formulate my question as webdeveloping is quite new to me. -
