How do I resolve the following error in Django: "OperationalError: foreign key mismatch"
I'm getting the following error whenever I attempt to save to the table in a SQLite database: foreign key mismatch - "procedure_tbl" referencing "filename_tbl" In models.py, these are the tables that the error is referring to: class FilenameTbl(models.Model): rowid = models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='FileID', db_column='rowid') filename = models.TextField(blank=True, null=True) creation_datetime = models.TextField(blank=True, null=True) class Meta: managed = False db_table = 'filename_tbl' ordering = ['rowid'] class ProcedureTbl(models.Model): rowid = models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ProcedureID', db_column='rowid') ... filename_id = models.ForeignKey(FilenameTbl,db_column='filename_id', to_field='rowid',null=True,blank=True,on_delete=models.SET_NULL) class Meta: managed = False db_table = 'procedure_tbl' ordering = ['rowid'] Data can be read from the tables and querysets like the following return the correct data: queryset = FilenameTbl.objects.values( 'rowid', 'filename', 'proceduretbl__rowid') Raw SQLite commands to write/update to the ProcedureTbl table function properly. If I removed filename_id from the ProcedureTbl, then data can be saved to the table. -
Azure active directory SAML SSO configuration issue with Django backend
I am trying to set up SAML Single Sign-On (SSO) with my Django app, but I am getting an error when I try to login to my app. I go to the app url, Microsoft processes the request (the url displays microsoft.loginonline.com/etc briefly), and then I get redirected to this page: https://my-app.azurewebsites.net/.auth/login/aad/callback which displays this error: {"code":400,"message":"IDX10501: Signature validation failed. Unable to match keys: \nkid: '[PII is hidden]', \ntoken: '[PII is hidden]'."} The reply url is set to: https://my-app.azurewebsites.net/.auth/login/aad/callback I did the set-up following both the Azure docs and following this documentation: https://django-auth-adfs.readthedocs.io, it's ostensibly working on my localhost, just not on the actual azure app service... I am unsure of what I am doing wrong, and the error message is not very informative for me as I am new to back-end programming and cloud. Any help appreciated, thanks! -
Django not auto-filling a new html file
starting to learn django, and in the video im watching django automatically fills minimum html code when you create a new html file in the templates folder, but its not happening for me. i can switch to HTML language mode and ctrl+space & choose HTML_sample, but its not the same code as shown in the video. is it just a pycharm thing? the video uses pycharm, but they say the Django autofills the code so didnt think it was the issue. the html files path: "project_name\app_name\templates\app_name" using VScode 3.9 and django 3.2.5. (had some trouble with django-html, had to add it manually to the settings.json) -
Django Rest: Why is the access denied, although AccessAny is set as permission?
I want to give all people, without any permissions access to my API.

502 Bad Gateway nginx/1.20.0 Error when Deploying Django app using AWS Elastic Beanstalk
I was following closely following AWS's documentation on how to deploy Django apps using Elastic Beanstalk until I received a 502 Bad Gateway nginx/1.20.0 Error when opening my app. From there, I followed a couple of solutions offered by users that suffered similar problems.

How can I test a single field in a form?
I want to create a test that would confirm that in case of a user not putting any input into the question field, the error will be raised. def test_new_question_form_no_question(self): form = NewQuestionForm(data={ 'question': "", 'choice1': "ok", 'choice2': "fred@example.com", 'choice3': None }) self.assertEqual(len(form.errors), 1) That would probably be a perfect solution, but it doesnt work for me. Here I'll show why: class NewQuestionForm(forms.Form): question = forms.CharField(label='Question', max_length=1000) set = re.compile(r'fuck') choice1 = forms.CharField(label="Choice 1", validators=[RegexValidator(regex=set, inverse_match=True)]) choice2 = MultiEmailField() choice3 = forms.BooleanField(required=False) def clean_choice2(self): data = self.cleaned_data['choice2'] if 'fred@example.com' not in data: raise ValidationError("You've forgotten about Fred") return data def clean(self): super().clean() cc_myself=self.cleaned_data['choice3'] subject = self.cleaned_data**['question']******** if cc_myself and subject and 'help' not in subject: msg="What are you doing?" self.add_error('question', msg) In the part, which i highlighted with ******, there is this reference to question and because i didnt put a question in a test, this part cannot be executed. Thats why i struggle with testing if the form accepts only a filled question field.

how to mount different volumes of your docker-compose with AWS EFS using django react and postgres
while using AWS ECS Fargate, how do we mount files in AWS EFS from the volumes of different applications being used in the docker-compose? version: "3.9" services: backend: build: ./backend restart: "on-failure" volumes: - ./backend:/backend <======= THIS ONE - ./backend/static:/backend/static <======= THIS ONE ports: - 8000:8000 ... db: image: postgres:latest restart: always volumes: - postgres_data:/var/lib/postgresql/data/ <======= THIS ONE ... frontend: build: ./frontend volumes: - ./frontend:/frontend <======= THIS ONE I have the above configuration of my docker-compose and what i am trying to achieve is to make sure all those volumes <=== THIS ONE persist no matter what happen to my AWS ECS Fargate Task From what i read i must use AWS EFS and define that option in the task definition, but my question is to know whether i could persist all of those volumes from my docker-compose at once when i provide the single path in AWS EFS or should i provide a single path for each one of the volume above? -
Django redirect and modify GET parameters
I am implementing magic tokens and would like clean URLs. As a consequence, I would like to remove the token from the URL upon a successful user authentication. This is my attempt: def authenticate_via_token(get_response): def middleware(request): if request.session.get('authenticated', None): pass else: token = request.GET.get('token', None) if token: mt = MagicToken.fetch_by_token(token) if mt: request.session['authenticated'] = mt.email if not request.GET._mutable: request.GET._mutable = True request.GET['token'] = None request.GET._mutable = False else: print("invalid token") response = get_response(request) return response return middleware IE, I would like to send /products/product-detail/3?token=piyMlVMrmYblRwHcgwPEee --> /products/product-detail/3 It's possible that there may be additional GET parameters and I would like to keep them. Any input would be appreciated! -

How to delete django model data on button click
I am creating a donation application. I have a screen in which people can click on if they want to learn more about a specific donation. On that screen, I have the following button: <button class="btn btn-success"onclick="showAlert()">Accept</button> . When this button is clicked, I bring up a confirmation alert, which is down bellow.

When the alert comes up, if the user clicks the ok button, I want to delete the data that they are currently viewing and redirect them to another page.

How to use inter-process communication in django with discord.py and discord-ext-ipc
I'm currently using discord-ext-ipc as an inter-process communication (IPC) extension for discord.py and linked this with quart-discord. Quart is an asyncio reimplementation of Flask and can natively serve WebSockets and other asynchronous stuff. I can so easily use a Web-Frontend as a Dashboard to interact with the discord users on a guild. Doing fun stuff like, using the discord role model for a permission model at the dashboard. Recently I stumbled over django and got hooked up with that powerful framework. As a learning project, I wanted to port the current working project into django but I stumbled over some impasses. First the working example with discord-ext-ipc and quart-discord: bot.py import logging import discord from discord.ext import commands, ipc intents = discord.Intents.default() logging.basicConfig(level=logging.DEBUG) TOKEN = DISCORD_TOKEN class MyBot(commands.Bot): def __init__(self,*args,**kwargs): super().__init__(*args,**kwargs) self.ipc = ipc.Server(self,secret_key = IPC_SECRET_KEY) async def on_ready(self): """Called upon the READY event""" print("Bot is ready.") async def on_ipc_ready(self): """Called upon the IPC Server being ready""" print("Ipc server is ready.") async def on_ipc_error(self, endpoint, error): """Called upon an error being raised within an IPC route""" print(endpoint, "raised", error) my_bot = MyBot(command_prefix = ">", intents = intents, chunk_guilds_at_startup = False) @my_bot.ipc.route() async def get_guild_ids(data): final = [] for guild in … -
How to add Query String Auth on all files in Django with Amazon S3

Django Slugs as principal url
I want to do the following, so that the profile of each registered user can be seen as follows: http://127.0.0.1:8000/username/ I was able to achieve this, the problem is when wanting to create another page, for example http://127.0.0.1:8000/explore/ Django consider "explore" as a user and throw me a 404 error. this is my urls.py urlpatterns = [ path("<slug:slug>/", PerfilView.as_view(), name="perfil"), path("explore/", UserListView.as_view(), name="explore"), ] Am I doing it the right way or am I unable to do this with django?

Replace Default PK slug with Multiple Lookup Fields for ModelViewSet
I have two slugs, against which I run queries. Thanks to base class MultipleFieldLookupMixin, which my view class is inherited from and thus allows me to have multiple lookup_fields. We know that when ModelViewSet is used with DefaultRouter, appends a pk at the end of URL, which I don't want. For example, when I do this: router = DefaultRouter() router.register(r'organization', OrganizationModelViewSet, basename='organization') urlpatterns = [ path('viewset/', include(router.urls)), path('viewset/<str:device>/<str:start_time>/', include(router.urls)) ] it gives me the URL mydomain.com/viewset/<str:device>/<str:start_time>/organization/<int:pk>/ I don't want this pk at the end. If we can remove organization, that's even better. I want the endpoint to be, mydomain.com/<str:device>/<str:start_time>/. More playing around, I learned that adding extra_kwargs like this in my serializer class, extra_kwargs = { 'url': {'lookup_field': 'start_time'} } and modify lookup_fields in view class, with singular lookup field, like lookup_field, with value let's say, start_time. To clarify, changing lookup_fields = ["device", "start_time"] with lookup_field = "start_time" and also modify the URL accordingly by removing the start_time slug, then URL becomes mydomain.com/viewset/<str:device>/organization/<str:start_time>/ modify singular lookup_field with org, apparently gives us more or less the desired URL, but doesn't get the job done because we have a single lookup_field now! mydomain.com/viewset/str:device/organization/str:start_time/ If we edit this line router.register(r'organization', DeviceActivityModelViewSet, basename='device_activity') to … -
How to implement only accepting username and token as request in django view and not password?
I have created a custom User model in Django that has username, email, password and some other fields. I am using jwt token which can be acquired from /token after providing valid username and password of a user. I have created a serializer for /authstatus and implemented it's view in views.py. Currently it works only when both username and password are provided with authentication token as header. Is there any way to ask only username and not password from user as a request for /authstatus?
