Django 3: Multiple forms in one view
What I'm trying to do is creating an employee where we need to complete the employee profile with Private, Address and Contact form. I have tried 2 things. The first option was creating in de models.py from the app, 3 models: Model for Private class Private(models.Model): GENDER = ( ("Man", "Man"), ("Woman", "Woman"), ) gender = models.CharField("Gender", max_length=15, blank=True, choices=GENDER) initial = models.CharField("Initial", max_length = 15, null=True, blank=True) first_name = models.CharField("First name", max_length=30, blank=True) insertion = models.CharField("Insertion", max_length = 15, null=True, blank=True) last_name = models.CharField("Last name", max_length=30, blank=True, null=True) The second model for Address: class Address(models.Model): street_name = models.CharField("Street name", max_length=80, null=True, blank=True) house_number = models.CharField("House number", max_length=6, null=True, blank=True) Model for Contact class Contact(models.Model): Phone = models.CharField("Phone", max_length=14, null=True, blank=True) email = models.CharField("E-mail", max_length=80, null=True, blank=True) In forms.py from the app I also created 3 forms for each model above. In the Meta class the variable model is linking to each Model. In views.py we have this: def createEmployeePersonal(request): employeeprivate = Private() employeeaddress = Address() employeecontact = Contact() if request.method == "POST": employeeprivate = Private(request.POST) employeeaddress = Address(request.POST) employeecontact = Contact(request.POST, request.FILES) if employeeprivate.is_valid() and employeecontact.is_valid() and employeecontact.is_valid(): employeeprivate.save() employeeaddress.save() employeecontact.save() return redirect("/employees") context = { "employeeprivate": employeeprivate, "employeeaddress": … -
How to map form input to django user model?

Django URL and Template with inbuilt authentication
I am a Django Beginner, I started by reading WS Vincent..The book created a customUser model in a separate App name USERS. Also, AUTH_USER_MODEL = 'users.CustomUser' has been set up. I have below question related to URLS and Templates . Any help will be appreciated I have been reading that the Default Django login path will go to /accounts/login. However , when I used {% url login %} in template base.html it routed to users/login. That would be coz fo Auth_user_model, but I want to be sure how the above tag would fit in below URL's because there is still no accounts/login URL. If it is getting that from auth.urls package then it only has everything starting with /accounts not /user. I did a packet capture thinking it might be translating to account/login but destination was still users/login. .I hope I was able to explain my query. Please help. urlpatterns = [ path('admin/', admin.site.urls), path('users/', include('users.urls')), # new path('users/', include('django.contrib.auth.urls')),# new path('', TemplateView.as_view(template_name='home.html'),name='home'), # new ] -

use manytomany field in both the models Django
I have two models named Profile and Controversy. My requirement is many people can be involved in a controversy and a single person can have multiple Controversies. With that said, I feel like I should a ManyToMany field in both the models but I'm guessing that violates ManyToMany fields documentation as it should be used in only model. my models are as follows : class Profile(models.model): name = models.CharField(max_length=200) Controversy = models.ManyToManyField(Controversy) # As one person can have multiple controveries class Controversy(models.Model): year = models.Datefield() other_people_involved = models.ManytoManyField(profile) # As multiple people can be involved in a controversy description = models.TextField() This obviously will throw error.

Django - 'QuerySet' object has no attribute 'get_upvotes_count'
I am a beginner at Django and I am trying to build an app to manage games. It is possible for registered visitors to rate the game. Furthermore you can comment the game and this comment can be rated as well. But only once. The difficult thing for me is the independent evaluation of comments and articles. Furthermore, the "Queryset" error message occurs when I create a game. I already tried to initialize the attribute "comment" in the views with "None". Did not work. How do I get the app running ?

AttributeError: module 'enum' has no attribute 'IntFlag' from Azure
I have a Django project running on Azure, and I encountered this issue with the enum module and I have tried everything from here(Why Python 3.6.1 throws AttributeError: module 'enum' has no attribute 'IntFlag'?)

Can I serve static files (css, html, etc.) from a different server in Django
So I'm trying to serve templates, images, css and other static files from a Web Server (frontend) running Apache into an App Server (backend) running Django, the Django app is already proven to work locally so I splited static files and push them into the Web server and the .py files into the App Server, so far I've seen that I need to use mod_wsgi package from Apache and then run $ python manage.py collectstatic So it makes a copy of those static files into the App Server. But the problem comes when changing the urls of every template. Also I saw this other solution but I'm not sure if I implement that solution I still need to do the mod_wsgi thing. Can someone please help me out here please? Or give me some advice on how to do it? Thanks -

Django Post Deployment Issues - Scripts and Models
Hi it's my first time deploying a Django app. I'm using PythonAnywhere to host and learn more. I am aware that deployment requires additional steps and code changes versus dev and believe I have taken these steps researching the documentation and other issues on Stack Overflow. After separating out javascript from the html, migrating the models and collecting the static files I'm having a major issue with the style of the index file not inheriting the base layout as well as being running the javascript. Additionally drop downfields that are reading from models are not working. Note all other pages are inheriting the base file but are not linking to models either for dropdowns. I've reviewed the models and they are in place and populated. Likely I am missing something with the base layout file and the models. Greatly appreciate if someone can point me in the right direction.

Restricting Signal Notifications in a Django Project to specific Attribute in Model
I have added a notification everytime a user submits a Like button to a post, the owner of the liked post receives a notification. I have set Value options for each Like button to be Like or Unlike so now I am trying to restrict the notification to be sent only if the Value of the like clicked is Like only. So, now in the Like Model I have added signal and a condition that if the Like.value== Like the signal activates but for some reason it is not working and I am not sure why. My question is: How do I set the notification signal to be sent only when the Like.value== Like?

how to set a timer or schedule non-periodical task in Django > 3.0 and DRF
Im new to async programming and new Django's docs aren't really specific what should and should not be done so here is my question. How to set some kind of a timer in Django (or django-programatically in server) after which some Django code will be run. To visualize this I will present an example: Student has 10 minutes to write a test. Student starts a test (enters some view). Student can post his test results within those 10 minutes but if he crosses the 10 minute barrier, the test should stop and such event should be saved in database. This sounds like an async job but I don't know the good practise for coding that. If it can be done synchornousily it would be much better. To clarify - I'm using Django REST framework and the student is on a mobile client. (setting a timer in mobile app is not an option due to security reasons). I know about Celery but it seems like an overkill when Django already has async. I will add that there will be several tousand student tests running at the same time so performance is important. Can anyone help me or point me to a … -

Store a matrix in Django
I have the following matrix: item_1 item_2 item_3 item_1 1 0 0 item_2 0 2 0 item_3 0 0 3 What is the best way to store this matrix into django, so that in the future I can retrieve an entire column (being able to see the ID of each row), and use it to perform some calculations in a view? Obs: This matrix is going to have thousands of columns and rows.
