Django NoReverseMatch Error with Stripe Payment
I am unable to resolve this error. Please advise. I have the base app, fundraiser app, and donation app (which has Stripe installed). Donations was working fine before I tried to append donations onto fundraiser since a donation should be tied to a specific fundraiser. Landing on homepage shows you an index of all fundraisers as well as login/logout functionality. Clicking a fundraiser will take you to the fundraiser show page as /show/id. The show page has a button that will take you to a form for payment /show/id/donate. Entering the donation info (name/credit card info) and clicking donate button should initialize the charge view functionality for stripe to operate. Instead I get NoReverseMatch at /show/9/donate Reverse for 'charge' with no arguments not found. 1 pattern(s) tried: ['show/(?P[0-9]+)/donate/charge/$'] Request Method: GET Request URL: http://127.0.0.1:8000/show/9/donate Base App URLs urlpatterns = [ path('', include('fundraisers.urls')), path('show/<int:id>/donate/', include('donations.urls')), path('admin/', admin.site.urls), path('accounts/', include('accounts.urls')), path('accounts/', include('django.contrib.auth.urls')) ] Fundraisers App URLs urlpatterns = [ path('' , views.index, name='index'), path('create', views.create, name='create'), path('show/<int:id>', views.show, name='show'), path('show/<int:id>/donate', views.donate, name='donate') ] Donations App URLs urlpatterns = [ path('', views.index, name="index"), path('charge/', views.charge, name="charge"), path('success/<str:args>/', views.successMsg, name="success"), ] Fundraisers App Views def index(request): fundraisers = Fundraiser.objects.all() return render(request, 'fundraisers/index.html', { 'fundraisers': … -
Local.py and prod.py settings files in .gitignore for Django
I have set up two settings.py files, local.py and production.py. In my __init__.py, I have this: from .base import * from .production import * try: from .local import * except: pass The idea is that local.py is in the .gitignore file, so that when I push it to my web server on AWS Elastic Beanstalk, the try except fails because the local.py file is not pushed. However, I want the local.py file in GitHub so that other can collaborate. How can I achieve this? Thanks! -
How do I get Django connecting to SQL Server working with AWS Lambda Layers?
I am trying to use Django connected to SQL Server 2019 in an AWS Lambda function using Lambda Layers. I found an example using pyodbc to connect to SQL Server here: https://medium.com/@kuharan/aws-lambda-python-ms-sql-server-the-easy-way-e7667d371cc5. I downloaded the example Lambda Layer and Lambda function and was able to get that working. However, now I am trying to install Django and django-mssql-backend in the layer in order to use Django to connect to SQL Server 2019. Here is a screenshot of how the directory structure is setup with Django and django-mssql-backend installed: I zipped up the pyodbc-layers folder and uploaded that into Layers. Here is a screenshot of that: Then when I run my lambda function, I get the error: Response: { "errorMessage": "Unable to import module 'lambda_function': No module named 'django'", "errorType": "Runtime.ImportModuleError" } Here is a screenshot of my function and the error message: How do I resolve this?

How to obtain 'refresh_token' for an existing (expired) authentication token (django-oauth-toolkit)?
django-oauth-toolkit documentation (tutorial) shows how to obtain Bearer authentication token (access_token) and use it, and how to renew expired token using refresh_token. Question is: when long time is passed since access_token (and corresponding refresh_token) is obtained, user may no longer know what refresh_token value is... How exactly refresh_token can be obtained in that case? -
Django: How to make one-to-one link work in a serializer REST API setting?
I have made a UserSerializer from Django's default User and also a UserProfileSerializer from a custom model I made one-to-one linking to the Django default User. What the UserProfileSerializer have right now in addition to the Django default User is a "nickname" attribute. Now, I am making a RegisterSerializer to take in the "nickname" attribute from my front-end. However, I do not know how to correctly take in the "nickname" input from my front-end and encode that into my UserProfile database table. This is what I have so far: class UserProfileSerializer(serializers.ModelSerializer): class Meta: model = UserProfile fields = ('nickname') class UserSerializer(serializers.ModelSerializer): profile = UserProfileSerializer(source='userprofile') class Meta: model = User fields = ('id', 'username', 'email', 'password', 'profile') extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): profile_data = validated_data.pop('profile') user = User.objects.create(**validated_data) user.profile = UserProfile.objects.create(user=user, **profile_data) profile = user.get_profile() profile.save() user.save() return user class Meta: model = User fields = ('id', 'username', 'email', 'password', 'nickname') extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): user = User.objects.create_user( validated_data['username'], validated_data['email'], validated_data['password'], validated_data['nickname'] ) profile = user.get_profile() profile.save() user.save() return user However, I can't seem to do this because "nickname" is not a field from model User. -
How to bypass default file storage for testing purposes?
Hi we have a production server that uses a cloud to get some files. It's configured through DEFAULT_FILE_STORAGE in the settings.py. Our model is very simple, something like: def generate_filename(instance, filename): now = datetime.now(UTC) return f"generic_forwarder_import/" \ f"{instance.platform_customer.name}/" \ f"{now.year}/{now.month:02d}/{now.day:02d}/" \ f"{now.hour:02d}h{now.minute:02d}m-{filename}" class CompanyImport(models.Model): data = models.FileField(upload_to=generate_filename) In my unit test file, I'm trying to bypass default file storage like this (it's only a method from a class of type TestCase): def test_import_csv(self, file_name): base_name = file_name.split('/')[-1] platform_c_name = base_name.split('.')[0] # Using FileSystemStorage with TemporaryDirectory() as tmp_dir: fs = FileSystemStorage(location=tmp_dir) with NamedTemporaryFile(mode='w+', encoding='utf-8', dir=tmp_dir) as tmp_file: test = fs.save(tmp_file.name, open(file_name, 'r')) c_i = CompanyImport.objects.create(data=test) c_i.save() c_i.delete() But the CompanyImport still uses de default file storage, whereas the test is actually specifying the whole saved file (the code works). How to bypass default file storage to use FileSystemStorage with my model? -

Import module that depends on module with same name

Jupyter notebook hanging due to Django runserver
Some time ago I made a simple Django application. Recently, I started using Jupyter notebooks for Python and was wondering if I could run my application from such a notebook. To test that, I opened a new notebook and navigated to the top directory of the application: %cd d:\adressen To see if the application could be run from the notebook, I first tried: !py manage.py makemigrations It returned, as it should: No changes detected So far so good. Now starting the server: !py manage.py runserver In a sense nothing happend. No output, the cell label still showing as In[*]. Nevertheless, the server was running, for if I opened in my webbrowser the page http:\\localhost:8000, my application turned up and all features were working. I fail to see why in the notebook makemigrations is handled correctly and runserver makes it hanging. The Jupyter console did not show anything that could have gone wrong. Having looked at some other questions and answers about Jupyter and Django, I installed django-extensions and included it in the installed apps. That did not help. When I start Jupyter with python manage.py shell_plus --notebook, open a new notebook and use the same commands, the same happens. Any … -

Parse data from ajax call to Django view
I was coding a super simple chat app on Django, and using an Ajax load() function to query all messages on a database based on the user and the printing them on the screen, but now I was wondering if there's a way of handling the data that Ajax receives with a Django view itself. This is the current views.py: def app(request): if request.method == 'POST': form = NewMessage(request.POST) if form.is_valid(): msg = form.cleaned_data.get("message") to = form.cleaned_data.get("to") sender = form.cleaned_data.get("sender") sent = form.cleaned_data.get("sent") print(msg, to, sender, sent) form.save() return render(request, 'app/app.html') def messages(request): messages = Message.objects.filter(to=request.user.address) messages_json = [{'message':message.message, 'sender':message.sender, 'receiver':message.to, 'sent':str(message.sent)} for message in messages] data = json.dumps(messages_json) #return render(request, 'app/app.html', context={'messages':data}) return HttpResponse(data, content_type='application/json') And this is the current ajax call on app.html: setInterval(function(){ $.ajax({ url: 'http://127.0.0.1:8000/messages/', dataType:'json', success: function(data) { var div = document.getElementById('mydiv').innerHTML = JSON.stringfy(data) } }, error: function(data) { console.log(data) } }); }, 3000); This actually works without any issues, but I just want to know if there would be somehow to set this on Django views.py: def messages(request): messages = Message.objects.filter(to=request.user.address) messages_json = [{'message':message.message, 'sender':message.sender, 'receiver':message.to, 'sent':str(message.sent)} for message in messages] data = json.dumps(messages_json) return render(request, 'app/app.html', context={'messages':data}) So that everytime the ajax call … -

Sorry, I am a beginner. How to pass the variable / value x = "ABCDE" to the form? #views.py ... x = "ABCDE" form1 = KSS_Form1(initial={'x':x}) context = {'form':form1, **context} return render(request, 'af/size/01_kss_size2.html', context) #forms.py class KSS_Form1(forms.Form): mat_geh_innen = forms.ChoiceField(choices=[], widget=forms.Select()) def __init__(self, *args, **kwargs): super(KSS_Form1, self).__init__(*args, **kwargs) self.initial['mat_geh_innen'] = x self.fields['mat_geh_innen'].choices = \ [(i.id, "Housing: " + i.mat_housing.descr) \ for i in afc_select_housing_innenteile.objects.filter(Q(series__valuefg__exact=x) & Q(anw_01=True))] as for now I get an error message Exception Value: name 'x' is not defined How shall I pass 2, 3, or more values if I have a number of different ChoiceFields in the Form? Thank you
