Will Django Migrations result in conflicts with distributed version control?
I'm planning to work on a Django project with several collegues via Gitlab. Let developer A create a model on branch feature/model_a: class model_A(models.Model): field_A = models.CharField(...) Dev A runs makemigrations, receives a migration file (something like 0001_migration) and commits and pushes it to the remote repository. Now Dev B develops another model on feature/model_b: class model_B(models.Model): field_B = models.CharField(...) and also creates a migration file (Django will call this migration file also 0001_migration!). So given that the two developers develop their models on separate branches (which I believe is a good and recommended practice), they will now have a repository conflict. What are recommended and proven ways to prevent this problem? -
How can i Register and Login In The Same Page in Django?
i would like to have both my login form and my registration form on the same page within the same template, so i would like to have them under one view function but i am not too sure on how i can do that, here is my code. Views.py def register(request): form = CreateUserForm() if request.method == 'POST': form = CreateUserForm(request.POST) == "Register" if form.is_valid(): form.save() user = form.cleaned_data.get('username') messages.success(request,"Account was Created for " + user) context = {'form':form} return render(request,'login.html',context) def login(request): if request.method == "POST": if request.POST.get('submit') == 'Login': username = request.POST.get('username') password = request.POST.get('password1') user = authenticate(request, username=username, password=password) if user is not None: login(request,user) return redirect('shop.html') else: messages.info(request, 'Wrong Username or password') context = {} return render(request,'shop.html',context) login.html <div class="formBx"> <form method="POST",name="Login",value="Login"> {% csrf_token %} <h2>Sign In</h2> {{form.username}} {{form.password1}} <input type="submit" name="submit" value="Login"> <p class="signup">Don't have an Account?<a href="#" onclick="toggleForm();">Sign Up.</a></p> {% for message in messages %} <p id="messages">{{message}}</p> {% endfor %} </form> </div> </div> <div class="user signUpBx"> <div class="formBx"> <form method="POST" value="Register"> {% csrf_token %} <h2>Create an account</h2> {{form.username}} {{form.email}} {{form.password1}} {{form.password2}} <input type="submit" name="submit" value="Register"> <p class="signup">Already Have an Account?<a href="#" onclick="toggleForm();">Sign In.</a></p> {% for message in messages %} <p id="messages">{{message}}</p> {% endfor %} … -
What is the Django way to add data to a form that is already instantiated?
Suppose you have a ModelForm to which you have already binded the data from a request.POST. If there are fields of the ModelForm that I don't want the user to have to fill in and that are therefore not shown in the form (ex: the user is already logged in, I don't want the user to fill a 'author' field, I can get that from request.user), what is the 'Django' way of doing it ? class RandomView(View): ... def post(self, request, *args, **kwargs): form = RandomForm(request.POST) form.fill_remaining_form_fields(request) ### How would you implement this ??? if form.is_valid(): ... I have tried adding the fields to the form instance (ex: self.data['author'] = request.user) but given its a QueryDict it is immutable so it clearly isn't the correct way of doing this. Any suggestions ? -

Django cannot access dictionary, returns blank

I am accessing the values as follows: {% for showing in film.key %} ...Code here {% endfor %} I am printing out the data to my screen every time, so I know there is data there, because the headings register too. Unsure what is happening or what I am doing wrong. Fairly new to Django so pls be nice :) -

Django ModelViewSet. How to merge two perfrom methods/functions?
Is there a way to merge perform methods/functions? The view uses ModelViewSet. I have two functions perform_create and perform_update that do the same thing and I wondered could I merge them somehow?

File access issues with django and gunicorn
I’m wondering how file permissions work on Django. I have created a file debug.log where I want my logging to output. Its permissions look like this -rw-rw-r-- 1 ubuntu ubuntu 0 Apr 3 19:16 debug.log I have a Django superuser called ubuntu who I think should have rw access to this file based on what this says. However, when I run systemctl status gunicorn, I get File "/usr/lib/python3.8/logging/config.py", line 570, in configure raise ValueError('Unable to configure handler ' ValueError: Unable to configure handler 'file' Which according to this post Should mean that either the file doesn’t exist, or my user doesn’t have access. The filename has value os.path.join(BASE_DIR, 'debug.log'). And if I print that value out, I get /home/ubuntu/ACE/rangr/debug.log which is where the debug.log file is. Does anyone know why my django user doesn't have access to debug.log or why django thinks the file doesn't exist? -
Update django app every 30 days after deployement
I have build a DJango app and now I want to deploy it. As this is very first time for me to deploy django app so I am confused on what platform to use. I am thinking to use AWS. could someone help me and answer my questions for few things. Please don't judge me for my questions. How to deploy my app on AWS? How will I connect my app to the database and where will I get the Database?

The third point is very important as I need to update my app every month. Thanks in advance and please let me know if someone can help me out in this. -

compile django app to executable using PyInstaller
I am trying to compile a Django app as an executable. I know that this is not best practice - the app was built as a server app running on log in, but now the app shall be used by Users who shall not have access to the server. The challenge is now to make the app installable in such a way that the average Windows user is capable of double-clicking the exe and type in the url in a browser of their choice. I am working on Linux with Django 3.2.7, Python 3.8 and PyInstaller 4.1 (I know that I must compile on a windows platform for Windows OS to run the exe, but I first wanted to try using PyInstaller on my OS). Now, when starting the app, it complains not to find a specific folder in the dist directory, which when I add the demanded folder, changes to file not found "settings.pyc". ".pyc" files are compiled Python files, but I cannot grep the filename, so PyInstaller did not even create it. I executed the PyInstaller command in the directory where the first "mysite" is located. I also tried to separately hook the "myapp" folder by adding a … -

How to get the json key and value in Django's Templating language?
I'm trying to build a website for tv series using Django framework, I put in the models.py all kinds of details about that show and a JSONField to define the number seasons and episodes in each season. Example: { "s1" : 15 , "s2" : 25 , "s3" : 23} I made a dropdown in the template where the series is playing so the user can select the episode the problem starts when I try to access the values of the keys in the JSON object passed. I tried that: {% for key in show.episodes %} Season {{key}} {% for value in show.episodes[{{key}}] %} {{ value }} {% endfor %} {% endfor %} But it this is not working, I assume that the [] thing in js doesn't work in Django's Templating language, but I cant seem to find any solution. -

Start async event loop with n tasks from sync function
In my Django webapp, I have a method that emails all subscribers a notification whenever a new blog post is created. Executing this method is time-consuming, and I'm trying to make it more efficient with python's asyncio library. My motive is not just for the sake of performance, but also because my web server times out any form submissions that take longer than 300 seconds (including the form that creates new blog posts, and hence emails all subscribers). I'm assuming it's not wise to make a timeout window much longer than that, and I know that executing this method is only going to take more time the more subscriber objects I have. So, I'm thinking some sort of async solution is the way to go. Anyways, enough rambling. Here is what I've tried: # This method gets called every time a new blog post (agpost) is saved for the first time. def send_subs_new_post_email(agpost): logger.info("Setting up async emailing loop...") loop = asyncio.new_event_loop() asyncio.set_event_loop(loop) loop.run_until_complete(setup_async_sub_email_loop(agpost, loop)) loop.close() # Add a send_email task in the event loop for every subscriber. async def setup_async_sub_email_loop(agpost, loop): for i, sub in enumerate(Subscriber.objects.all()): domain = Site.objects.get_current().domain absolute_path = 'https://' + str(format(domain)) # Build unsubscribe link token = … -

Extending functionality of an external package's View in Django
I'd like to extend the functionality of a specific View in an external package that initiate SSO authentication with SAML. the package: https://github.com/zibasec/django-saml2-pro-auth I have a service that uses the package and logs in users from multiple apps, right now the sso login works but i'd like to extend specifically the SsoView - view of the package such that I could save the referrer so I know where to return to when I finish the authentication I guess it happens because I call the view from within my View and the namespace of my urls is not the same as theirs - in theirs the app_name is indeed saml2_pro_auth. Is there a better way to extend the View or solve this issue? Thanks in advance I tried to write a view in my app's views that uses the SsoView but it gives me "saml2_pro_auth is not a registered namespace" error of django when it is trying to reverse a url.
