I'm unable to save data to db in Django
Views.py I was trying to save this data that I'm getting from form but I'm unable to save it..it is going for the exception. I think the error is in the following line q = Query(sender=s, subject=subject, message=message, receiver=receiver) class SendQuery(View): def get(self, request): user=request.user if user.is_authenticated: try: s = Student.objects.get(user=user) ###Common code for students op = Staff.objects.filter(stype="1") return render(request,'students/send_query.html',{'s':s,'op':op}) ###Common code for students except: return redirect('home') return redirect('logout') def post(self, request): user=request.user if user.is_authenticated: try: s = Student.objects.get(user=user) ###Common code for students receiver = request.POST.get('receiver') subject = request.POST.get('subject') message = request.POST.get('message') print(receiver,subject,message) if receiver != "None": print("Hello") q = Query(sender=s, subject=subject, message=message, receiver=receiver) q.save() # if t: msg="Query raised successfully" return render(request,'students/msg.html',{'msg':msg}) else: msg="Failed to raise issue.

How to implimanet backend of a Quiz Webiste?
I am planning to make a Quiz app using Django as a backend. Users would be able to make their own quizzes (mostly MCQ questions) and I needed help in figuring out the backend for it. So far my plan was to Have Users, Quiz, and Questions table. And use foreign Keys to connect Users to Their Quizzes and Quizzes to the Question. But this would result in way too many rows in the question table as Number of quizzes increases. Currently, I plan to use Django to make tables. I wanted to know if there is a way to probably make Tables dynamically or some other way to store quizzes data like JASON or some other way? If yes how would I be able to do so using django. I am open to any other suggestions. (not sure if required but I plan to use React for frontend) -
Why am I unable to migrate when other files use my models in Heroku?
For context, I have an application that works perfectly fine locally, after some fiddling with the database. It uses a react frontend, with a django backend for internal api calls. However, on a new, fresh download, with a new, fresh database, I always get an error saying relation "claims" does not exist, where Claims is the name of a table in my database, in the form of a model. I have been able to bypass this error by commenting out all code that uses the model, then slowly migrating every single table, one at a time, then uncommenting out the code that uses the model. This is incredibly tedious, but it works in a local environment. However, as I attempt to push this into production, I am using Heroku, and I am unable to make multiple commits in the same way, as it seems the database gets reset everytime there is a new update. Am I missing something? I feel as though there must be something I am doing incorrectly here, but I have not been able to find anything other than posts saying to reset all my migrations, and redoing the makemigrations command. This method hasn't worked for me … -

django live videos and real time chat with node js integration
I plan to build a web application that supports live, video, and real-time chatting Since I've never done anything like this before, I had to understand it well But with studying the topic, the situation became very complicated about what technique to use. I usually work with Django and React But with the research, people say this is very difficult. It is necessary to use Node I went to search for the integration of Node with Django and here I found a greater complexity. People say that you must use redis Pub/sub or that you work with the same database in both sides. Now I'm so distracted I don't see any document on what I want to reach The main question is: how can I integrate Node with Django to implement these functions You can help even with an untested idea or article, literally anything Thanks in advance -
Writing a Django Form while keeping HTML styling
I have a Django form that I have created manually in order to keep the format of the styling, but I realized that the form is compromised of several inputs and manually is taking too long to change each. I am also able to generate the form automatically using {{ form.as_p }} but I lose the HTML style format that I have below. Is there an easy way to make it instead of manually changing each input? This is the original HTML template that I am trying to keep </button> <div class="form-outline mb-4"> <input type="text" id="businessName" class="form-control" name="businessName" /> <label class="form-label" for="typeText" >Legal Business Name</label> </div> Here is the working Django form: {% if submitted %} Your forms has been submitted {% else %} <form method="post"> {% csrf_token %} {{ form.as_p }} <!-- Submit button --> <button type="submit" class="btn btn-primary btn-block mb-4" id="btn" > Submit </button> </form> Here is the views.py def add_form(request): submitted=False if request.method == 'POST': form = infoForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect('/?submitted=True') else: form = infoForm() if 'submitted' in request.GET: submitted=True return render(request, 'template/template.html',{'form':form, 'submitted':submitted}) Here is the form class infoForm(ModelForm): class Meta: model = Info fields = ['businessName'] Here is what I have tried: <div … -

redirect errot - NoReverseMatch: Reverse for 'edit' with keyword arguments '{'title': 'Python'}' not found
I'm working on an app that allows the user to create, show and edit an entry. right now i'm working on the editing function. what i'm trying to do is have an edit button (that's actually a form that sends data via hidden inputs) that sends the title of the entry to a view called trans whose sole purpose is redirect to the edit view, the reason i did this is so that when i'm working on the edit view, i can simplify the process where if the request method is GET it shows the page with the form where the user can edit the entry and if it's post the edit view can receive the changes and save them without worrying about the redirecting from the entry's page. The problem lies in the fact that everytime i click the edit button i get the error: NoReverseMatch at /wiki/trans Reverse for 'edit' with keyword arguments '{'title': 'Python'}' not found. I have checked over and over for any misspellings or issues in urls.py or any problems with the naming but i just can't find the bug. and it's frustrating because i thought that this would be the easiest part of the … -
Django parsing values of fields in models - Extracting pk
I'm completely lost on part of my Django website. I finally figured out a way to have the same model create a template and then use that template and create another post. This works and is ideal. Now I need to put them in different locations on the screen so I basically need two for-loops and a way to decipher the two(templates and posts off of templates) apart from each other. The model has a title and a content field. When a template is created the title always starts with "Temp: ". I'm completely lost on this because I need to parse through the model and not just use an HTML parser because the content won't already be on the page and there is more than just the title that needs to be moved. I need a way I think in the views.py file to get the pk of ALL titles that start with "Temp: " and the content field tied with it and return it in a variable to the HTML file. I have been working on this for 3 days now and I just really need help. -

ERROR: Could not install packages due to an EnvironmentError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443)
I have a Python 3.7 Django project, and I am trying to generate a PDF using ReportLab and WeasyPrint. I ran into an issue while installing WeasyPrint, and since attempting to install it I have received the same error message while trying to install any pip install in new virtual environments. This issue has persisted for two weeks now, please help! Versions and Pip List, all of these were installed during the same day without issue, reportlab was installed without error seconds before I attempted to install WeasyPrint. image-1 These are the versions and the current pip list.. everything else installed normally up to this point without issues. The Project also runs without error, with the exception of needing to build out this aspect. Here is the error that happened when running the pip install WeasyPrint. image-2 I also attempted to switch gears and use other solutions but now every pip install I run, even in new environments returns this error. I'm guessing it's an actual permissions issue on my computer? And I have no idea what that means and where to start trouble shooting that if that's my issue. -
Django - how to display related many-to-many field in choice field?
I’m building a web app using Django for my music collection. For each album, there are multiple songs, and each song has one or more composers. Here’s the song model: class Song(models.Model): title = models.CharField(max_length=50) composer = models.ManyToManyField(Artist) class Meta: ordering = ['title'] def __str__ (self): return self.title The Artist model contains firstname and lastname fields. There are a number of occurrences of songs with the same title, and the only way to distinguish between them is by the composer. Currently, when songs are loaded into a choice field, only the title appears, using def__str. I’ve tried to include the composers, but haven’t found a way to make it work. Any suggestiions? -

Celery/Django/Redis task getting executed multiple times
In my current project, what I need to do is to get data from 700+ endpoints and then send that data to another 700+ endpoints. My approach is to use Django Celery Redis, Put 70+ endpoints on each worker so that there are approx 10 workers which will retrieve the data and then post the data. For this, I am using Chord to do the parallel task and then calculate the time it takes. The problem is that Celery is running the same task multiple times. task_get_data is the main method that first gets the list of websites then splits it into groups of 70 each and then calls task_post_data using Chord. In the output below you can see website_A, website_B etc. multiple times, I have manually checked my data and everything and there is no repetition of websites but when the celery task is submitted, multiple entries are created. Also, Is there any way to monitor the number of workers and what are they processing? Below is the code os.environ.setdefault('DJANGO_SETTINGS_MODULE','django_backend.settings') app = Celery('django_backend', backend='redis://localhost:6379', broker='redis://localhost:6379') app.config_from_object('django.conf:settings', namespace='CELERY') # app.config_from_object('django.conf:settings') app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) @app.task(bind=True) def debug_task(self): print('Request: {0!r}'.format(self.request)) def post_data(json_obj, website): for items in json_obj: md = md + items['data'] n … -
How to write a real self-contained Django app?
They say Django apps should be self-contained. I find it hard to implement. My website has 3 apps. All have their own static and templates folders. But — like many other sites — they share same front-end design. The problem is, I have a very small form at the footer of each page to sign up for my newsletter. First, I have to define the database model in one of apps, which means the other two rely on that one. Second, the view to update the database should be defined in an app — naturally, the same app that defines the model — which again means the other two have to call that view. So, app1 provides the model and view, app2 and app3 use them; so they are not self-contained. Isn't this against the philosophy?
