After adding media to AWS S3, Django gives me a weird error whenever I access a page with a media file
The error is like this: ValueError at /postview/24 Required parameter name not set Request Method: GET Request URL: http://127.0.0.1:8000/postview/24 Django Version: 3.0.6 Exception Type: ValueError Exception Value: Required parameter name not set Exception Location: C:\Users\Lenovo\Desktop\src\env\lib\site-packages\boto3\resources\base.py in __init__, line 118 Python Executable: C:\Users\Lenovo\Desktop\src\env\scripts\python.exe Python Version: 3.8.3 Python Path: ['C:\\Users\\Lenovo\\Desktop\\src', 'C:\\Users\\Lenovo\\AppData\\Local\\Programs\\Python\\Python38-32\\python38.zip', 'C:\\Users\\Lenovo\\AppData\\Local\\Programs\\Python\\Python38-32\\DLLs', 'C:\\Users\\Lenovo\\AppData\\Local\\Programs\\Python\\Python38-32\\lib', 'C:\\Users\\Lenovo\\AppData\\Local\\Programs\\Python\\Python38-32', 'C:\\Users\\Lenovo\\Desktop\\src\\env', 'C:\\Users\\Lenovo\\Desktop\\src\\env\\lib\\site-packages'] Server time: Thu, 4 Jun 2020 11:16:39 +0300 Wich has no real correlation with S3 because the error is intercepted on line 34 for some reason.

django not cleaning up previous data
I have a django setup which does not include any models or data base. It is just simple HTML, JAVAscript and python. It seems like django is not cleaning up the previous run data. How to cleanup data from forms after every run? I am not making use of sessions also. I am new to django and don;t have much time to learn sessions and implement things. Can any one give a solution on how to cleanup data after every run? -
Django ORM bulk read query
I have a model called User which has a property called is_free() which runs a query like this @property def is_free(self): return User.objects.free_user().filter(id=self.id).exists() When i try to get multiple users and populate them using a for loop there are many SQL queries executed based on the number of users i am populating which is affecting the API timings. For Example - for user in selected_users: user_list.append({"id": job.id, "name": job.name, "is_free": job.is_free, "title_display": job.title_display}) Is there a better way to do this without changing the model? I am using Django 1.8 and Python 2.7 -
django makemigrations override to create migration files with custom names
I have a python2.7 django project (I know, I am in 20th century!) that has some models in it. I need to override makemigrations so that the migration filenames are of the form 0001.py, 0002.py and so on, and not like 0001_initial.py, 0002_model1.py and so on which is by default what happens. I already looked at how to create custom manage.py commands and I am able to override makemigrations command. Presently my code for the custom command (python2.7) looks like this: from django.core.management.commands.makemigrations import Command as CoreMakeMigrationsCommand class Command(CoreMakeMigrationsCommand): def handle(self, *args, **options): super(Command, self).handle(*args, **options) It is doing nothing more than calling the original makemigrations at the moment. I need to be able to modify the behaviour of how autodetector.py(which is part of the makemigrations flow) decides the naming of the files. In this file, there's method suggest_name as shown below: @classmethod def suggest_name(cls, ops): """ Given a set of operations, suggest a name for the migration they might represent. Names are not guaranteed to be unique, but put some effort into the fallback name to avoid VCS conflicts if possible.

New tags are created automatically when I edit my Django Post with django-taggit
Everytime I try to edit my post, django-taggit creates a new url for the existing tags. What is the reason behind it and how to fix it? Here is my edit post view. note = get_object_or_404(Note, pk=pk) if note.user != request.user: messages.error(request, 'You are not authenticated to perform this action') return redirect('notes') if request.method == 'POST': form = AddNoteForm(request.POST, instance=note) if form.is_valid(): form_data = form.save(commit=False) form_data.user = request.user form_data.save() form.save_m2m() return redirect('note_detail', slug=note.slug) else: form = AddNoteForm(initial={ 'note_title': note.note_title, 'note_content': note.note_content, 'tags': ','.join([i.slug for i in note.tags.all()]), }, instance=note) return render(request, 'modals/edit_note_modal.html', {'form': form} -
Upload an Image to Django Rest Framework using Requests Library
I am trying to make an api endpoint for creating a post, the user can choose whether they want to upload a text(tweet) or an image alone or both, I have a validate method in my serializer for if no image nor text is sent, but it's raising the error on every try regardless if what I sent it.

How can i write better Code for the views.py
Good Morning, i have a Question. I worked on my First Web-Application and now i finished the stuff and want to make the code a bit better. This Projekt is my Thesis Projekt too so they look into my Code and if thats too bad, ill get a bad Grade. So there are only two Points on my list, for now, which are pretty important. At first, the Projekt is for Automate some Office Stuff like Create Google or Git Repos. So we have many API Calls and we have many Buttons on this Page. To delete the User, add him or whatever. We have more than user ofc, but i dont have to listen everything. The Point now is, that i have a Tempplate where i have like 8 Buttons. Its a Management Panel where we can do tons of Actions. The Code for that is just ugly. Here is a small Example: if 'delete' in request.POST: todel = Employee.objects.get(id=id) deleteUser(request, todel, deleteOrArchive=0) if 'deactivate' in request.POST: todel = Employee.objects.get(id=id) deleteUser(request, todel, deleteOrArchive=1) So there are many Ifs like that. I use Function Based Views everywhere because i thought its not that good to use Class Based Views here. … -
How to juggle between a null value for a field in sql query
I have a sql query. It first gets all the songs from the playlists. These songs could have an entry in Block Song Table and possibly some songs may not have an entry in the block song model. So, for those songs who have an entry they will have an unblock_flag which is a boolean field and will carry either true or false. But, the concern is that those songs which will not have an entry in the block song model table, will have null values for unblock_flag. I studied nvl in SQL, but it didn't work properly. The field to be changed is core_blocksong.unblock_flag in the below query. So, if anyone can suggest any other ways to make this scenario work? select songs.id, songs.name, songs.artist, songs.album, songs.albumart, songs."albumartThumbnail", cpr.votes, is_requested, core_blocksong.unblock_flag from (select id, name, artist, album, albumart, "albumartThumbnail" from (select song_id from core_plsongassociation where playlist_id in (1477)) as sinpl left join songs on sinpl.song_id=id) as songs left join (select` song_id, votes, bool_or(user_id=null) as is_requested from (select * from core_priorityrequests where client_id=2876 and is_played=False) as clpr left join core_priorityrequests_requested_by on clpr.id=priorityrequests_id group by priorityrequests_id, song_id, votes) as cpr on songs.id=cpr.song_id left join core_blocksong on songs.id = core_blocksong.song_id where core_blocksong.unblock_flag='f'and … -
Cookies is not set in request header
I have a client-server application build with Angular 9 and Django and I am facing the following situation: After login, I receive the session-id in Response Header. Even if the browser sets this cookie and I am able to see it in Dev Tools > Application > Cookie, this cookie is not used in the subsequent requests. More exactly, if I make a request after login, my Django server shows that there is no session and the user is not logged in. I searched this problem on the Internet and I found out that I have to set {withCredentials: true} in request headers in my Angular project. I make an Interceptor to set {withCredentials: true} in every request header, but this is not working for me. I put this interceptor in Providers in AppModule in this way: providers: [[{provide: HTTP_INTERCEPTORS, useClass: AuthInterceptor, multi: true}]] Here is my code for the interceptor: @Injectable() export class AuthInterceptor implements HttpInterceptor { constructor(public auth: AuthService) { } intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { request = request.clone({ withCredentials: true }); return next.handle(request); } } This is my login in Angular: login() { // stop here if form is invalid if (!this.loginForm.valid) { return; } this.authService.login(this.loginForm.value) … -

Handling 404 status with SPA using Create React App and Django API backend
Sorry if this is a duplicate! I have a SPA created with CRA and React Router and a separate (not in the same project) backend with Django to handle all APIs. I would like to know what's the best approach to handle 404 page not found url's, but having it return 404 status. Because as we know, using the <Switch /> and having a router <Route component={NoMatch} key="404_not_found" /> will display the 404 page but not return the 404 status. Now there are some topics online regarding this but I don't seem to understand what would be the best approach for my scenario. 1st suggested solution Is using express - but if I use express do I need to have it as a separate project and have it act like a proxy? if yes then that would be tedious having 3 separate projects for one platform! Or would it be possible to add express on top of my CRA in the same project? I could not find anyway of doing this! Please advise if I should follow this approach. 2nd suggested solution Would be to serve the 404 from Django backend. This would be more ideal but I did not … -
What type of authentication should I use for Django with Flutter?
I was creating FLutter project with Django + Django Rest framework as backend. What I wanted to add to the app is the user authentication and I found some ways to achieve that such as Session authentication or token authentication. According to this article https://hackernoon.com/auth-headers-vs-jwt-vs-sessions-how-to-choose-the-right-auth-technique-for-apis-57e15edd053, if we want to add user authentication for mobile api, it is best to use token authentication since session authentication is not suited for mobile phones. Thus, what I want to ask is that Is it really best to use token authentication for mobile apis instead of session authentication? -

How can I download OpenCV processed video as a django httpresponse file/attachment

Testing - Assert Django-Notification Sent
I am using django-notifications and have a view which, upon a successful POST, sends a django-notification to the admin user. I am wanting to test that the notification is sent when the POST has been successfully submitted, but dont know how. Im unsure how to even test this. My only idea is to check that the django-notifications db field has a new entry added to it, but i have been unsuccessful. Im guessing I would check somehow similar to this: self.assertEqual(1, notify.objects.count()) test.py: from notifications.signals import notify def test_notification_sent_to_admin_on_success(self): # admin user needed to receive notification admin = User.objects.create_superuser('admin', id=1) # current user user = User.objects.create_superuser('username') self.client.force_login(user) referer = 'http://testserver{}'.format(reverse('final_question')) # POST to final_question sends the notification to admin self.client.post(reverse('final_question'), { 'final_question': 'When can I start' }, HTTP_REFERER=referer) # check that notification was sent to admin self.fail('Incomplete Test') -
creating API to do calculations in backed using DRF
This question might be simple, but I like to know the proper way of doing this. I want to create some APIs that lets end user to send a string to the backed, and backend does some calculations to extract entities, and returns Jason response containing a dictionary of these entities. So in this process, I really don't need any model, any serialization and as the result no CRUD happens in my views. I can use normal Django in my view to render Json response using: return JsonResponse(dic) Also my input is currently entered in a Django form. so my question is that: 1- what would be the correct url pattern if i don't use django form. How should I retrieve string in my view based on this pattern. 2- can I use DRF here or return JsonResponse(dic) is efficient enough, Thanks -

I have been struggling for a while in trying to correctly setup the settings.py to send an email for password reset.This is my current configuration: SENDGRID_API_KEY = os.environ["SENDGRID_API_KEY"] SENDGRID_PASSWORD= os.environ["SENDGRID_PASSWORD"] SENDGRID_USERNAME= os.environ["SENDGRID_USERNAME"] EMAIL_HOST = 'smtp.sendgrid.net' EMAIL_HOST_USER = os.environ['SENDGRID_USERNAME'] #EMAIL_HOST_USER = 'apikey' EMAIL_HOST_PASSWORD = os.environ["SENDGRID_PASSWORD"] EMAIL_PORT = 587 EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = os.environ["DEFAULT_FROM_EMAIL"] #SENDGRID_SANDBOX_MODE_IN_DEBUG = False EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' I have come across the following posts that are related to my problem but none of them have worked: Sending SMTP email with Django and Sendgrid on Heroku No module named 'sendgrid_backend' in django Send email with Sendgrid in Django Setting up email with Sendgrid in Heroku for a Django App When I used the EMAIL_BACKEND = "sendgrid_backend.SendgridBackend"(after I installed the django-sendgrid-v5 library) I didn't receive any error but I didn't receive any email :'( and in the previous cases I encountered the following error SMTPServerDisconnected at /password-reset/ and Connection unexpectedly closed. Any help, suggestion, comment, crazy idea is really appreciated because I have spent several hours in this problem that will be a milestone in my project. Thank you everyone :)
