How to get html from page in Django
I was trying to implement some testing in Django, and I needed to check the data on the web page with a string, but I couldn't retrieve data from the web page. so, how can I get data(html) from web page? my tests.py from rest_framework.test import APITestCase class TicketTestCase(APITestCase): def test_user_details_on_ticket_id(self): response = self.client.get(f"/api/ticket/1") print(response.content) # this returns empty data in bytes # I want to check this #self.assertEquals(response.data "helloworld") -
Cannot Filter ChoiceField in Django with Multiple Keys and One Value
I am trying to filter a choicefield in Django by attempting to display one value with multiple keys. I understand choicefields are normally one key per value, but I have some values (names) which are the same with different id's in my database. I do not want to display the names more than once in the choicefield, so I wrote code to display items of a dictionary as a tuple with several id's and one value. I would like to filter these objects (animals) by "species" and "gender," so I created two modelchoicefields in my form. I am able to filter singular names by "species" and "gender" but not the duplicate names. The only error messages I get are Not Found: /filter_species/(1, 4)/ and "GET /filter_gender/(1,%204)/ HTTP/1.1" 404 4306. The "1" and "4" are respectively id's 1 and 4 for two animals with the same name. I have included my code from my forms, views, URLs, and animals template. Any help would be much appreciated as I am fairly new to Django and am still learning. Note: I am wondering if my URLs may be an issue with not showing regex for the parenthesis (tuple)? If so, I've been researching … -

Django collectsatic keeps collecting old files
When I run my localserver I noticed that Django is loading a background image I changed a while ago. I checked the folder where my static files are and my new background image was there. Both images had the same name. I changed the name and did collectstatic again and in my STATIC_ROOT the old image appeared. Later I tried python manage.py collectstatic --clear, I also cleared my cache, restarted my server. I tried deleting the file and changing the name and the path and Django keeps collecting old static.

Django static file image into template 404 error
I am trying to load a picture into a a Django 3.1 Template. I followed the documentation on the https://docs.djangoproject.com/en/3.0/howto/static-files/ and looked elsewhere for an answer but was not able to solve the issue.

How to solve problem with Django & Mongo on azure appservice
I managed to develop django app with vs code but I couldnt publish it. I think I couldnt set up virtual env properly. But then I made it with normal visual studio and that created me virtual environment which azure accepted well. It was working well but with sqlite. I needed mongoDB. I found instructions for dns and djongo and settings.py, so on terminal: 'python manage.py runserver' (locally, but with atlas mongo) it works well. But now, azure isn´t accepting my app. It says only SQL this and that XXXX are accepted... Could someone help me? Heres all the code: https://github.com/Point-SimoSiren/django-suppliers It is now again with sqlite but setting.py: DATABASES mongo stuff I used are on comments right below that. Only virtual env code is in github repo. -

wordpress + nginx + django: error too many redirect
I have just included wordpress into a project to replace django for the landing page of the website. Up to that point everything server related is working just fine.

Django HttpResponse returning object instead of stated string
I am using Django and React. I need to send a string from Django to React. I have tried using both HttpResponse and JsonResponse but both seem to be returning a response object that does not include the data. The response object from React looks like this: Response {type: "cors", url: "http://localhost:8000/post/", redirected: false, status: 200, ok: true, …} body: (...) bodyUsed: false headers: Headers {} ok: true redirected: false status: 200 statusText: "OK" type: "cors" url: "http://localhost:8000/post/" __proto__: Response Here is my Django from django.http import HttpResponse, JsonResponse def index(request): string1 = "" if request.method == 'POST': # ...processing upload... string1 = "Hello World" return HttpResponse(string1) And my react request looks like this: async function handleSubmit(event) { let formData = new FormData(); formData.append(file) fetch("http://localhost:8000/post/", { method: "POST", body: formData, enctype: "multipart/form-data", }).then((res) => { console.log(res); }); How can I get the data I need (string1) included in the response object (or without the response object)? I've looked on StackOverflow and around the web and haven't found a solution. I am also not sure whether this is a problem with Django or React but it seems like a Django problem. (Also, I don't believe it is a CORS Problem as … -

Django DRF (De-)Serializer not working for me?
I'm stumled upon a case I don't understand. I have two related models: class Course(models.Model): code = models.CharField(max_length=10, default='') semester = models.CharField(max_length=10, default='') class Meta: unique_together = [['code', 'semester']] and: class StudentWork(models.Model): code = models.CharField(max_length=10, default='') course = models.ForeignKey(Course,on_delete=models.CASCADE, related_name='student_works') deadline = models.DateTimeField(blank=True) In the StudentWorkSerializer I'd like to expand a course field into [code, semester]: class CourseNaturalSerializer(serializers.ModelSerializer): class Meta: model = Course fields = ['code', 'semester'] class StudentWorkWithCourseSerializer(serializers.ModelSerializer): course = CourseNaturalSerializer(read_only=True) class Meta: model = StudentWork fields = ['code', 'course', 'deadline'] This works nicely for GET, e.g. I receive this: {'code': 'HW1', 'course': {'code': 'T101', 'semester': 'S20'}, 'deadline': '2020-09-04T23:59:00+03:00'} but this does not work for POST: POST /studentworks json=dict(code='HW2', course={"code": "T101", "semester": "S20"}, deadline="2020-09-04T23:59") says in the stacktrace: django.db.utils.IntegrityError: NOT NULL constraint failed: botdb_studentwork.course_id So this looks to me that {"code": "T101", "semester": "S20"} does not de-serialize into Course object and it's id is not passed to StudentWork's create? What should I do? Thanks in advance! -
Django form not submitting in POST
Been having an issue where I am unable to upload files into my form. From what I can gather on my own, it's because I'm not submitting in POST (since uploaded files aren't saved unless you're in POST) but I don't know why that's the case. Here's my code: Views.py def commission(request): if request.method == "POST": form = CommissionForm(request.POST) if form.is_valid(): subject = str(form.cleaned_data.get("name")) + "'s commission request" message = form.cleaned_data.get("name") + ",\nhas requested a commission, with the following request:\n" + form.cleaned_data.get("request") + "\n Reply to them using their email:\n" + form.cleaned_data['email'] email = form.cleaned_data['email'] print(form.cleaned_data) attach = request.FILES['reference'] try: mail = EmailMessage(subject, message, settings.EMAIL_HOST_USER, [email]) if attach != None: mail.attach(attach.name, attach.read(), attach.content_type) mail.send() return redirect("main-commissions-success") except: return render(request, "main/commissions.html", {"form": form}) return render(request, "main/commissions.html", {"form": form}) else: form = CommissionForm() return render(request, "main/commissions.html", {"form": form}) Commissions.html <div class="row"> <div class="content-section card w-50 mx-auto my-5"> <div class="card-body"> <form method="POST" action="" class="border border-light m-10" enctype="multipart/form-data"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4 text-center">Request A Painting</legend> {{ form|crispy }} </fieldset> <div class="form-group text-center"> <button class="btn btn-outline-info" type="submit">Send Request</button> </div> </form> </div> </div> </div> And since this has no model relation, I'm not going to bother adding it here.

Django Extended Group's Permissions not applied to users
So I have extended Django's Group model to add an extra field like so: class MyModel(Group): extra_field = models.TextField(null=True, blank=True) On doing this, each instance of MyModel created, creates a Group instance as well. If I add a user to the resulting group with user.groups.add(group), the group is added as expected. However, the permissions from the MyModel group do not seem to have trickled down to the user i.e Doing user.get_all_permissions(), get_group_permissions() or even testing a user.has_permission(mygroup_permission) returns nothing. Only permissions from pure Group instances(created before extending the model) are shown. Is there anything I need to do for permissions on customised groups to be visible on the users? TIA -

Django: changes made to settings.py are ignored - Production - Gunicorn (with supervisor)
I have my Django application running on an Ubuntu server and I am using gunicorn and supervisor. From when I pulled the first version of the project from GitHub, all the changes made to the Settigs.py file are being ignored and the application is running with the first version of the settings file even after numerous pulls from GitHub. If I cd in my project directory and I view the settings.py file I can see that it is up to date, but all the changes it has got from the first upload are being ignored. I tried to restart supervisor with supervisorctl restart app_name but that doesn't resolve the issue. The app is still running with the first version of the settings.py file. I also made some research for a way to restart gunicorn and foun these commands: sudo systemctl daemon-reload sudo systemctl restart gunicorn sudo nginx -t && sudo systemctl restart nginx but when I run the second command I get this error Failed to restart gunicorn.service: Unit gunicorn.service not found. Any ideas to why all my changes to the settings.py file are being ignored? Thanks in advance. -
Customize Django login without creating custom user?
I am trying to create a Django login that will accept both email or username. I know that it is possible to do this by creating a custom user, but we have multiple applications already that reference the Django base user, so I would prefer to avoid having to go through and change all of those. I have a model that is strictly for the user profile, and includes a required, unique email field. Is there any way to customize the Django login to validate email against that user profile model so that I don't have to create a custom user? -
