How can I solve the "Cookie csrftoken will be soon rejected because it has the sameSite attribute set to none" warning on my Django 2.0 application?
I am using version 2.0 and I just noticed on my firefox developer tools this message: Cookie “csrftoken” will be soon rejected because it has the “sameSite” attribute set to “none” or an invalid value. It seems that django 2.0 does not store SameSite attribute along with this cookie. (for example something like this: Set-Cookie: CookieName=CookieValue; SameSite=Lax;) Is there a workaround for this? Or am I doing something wrong? -

I am using hawthorn version open edX, Also using scorm xblock https://github.com/overhangio/openedx-scorm-xblock for upload the scorm. by default, it is using /edx/var/edxapp/media/scorm/ path. I want to change the storage location. For this, I have tried two solutions. First solution:- In the lms.env.json and cms.env.json change the path. MEDIA_ROOT = /my/new/path/media/ MEDIA_URL = /media/ Also, added below the line in url.py urlpatterns = patterns('',# ... the rest of your URLconf goes here ...) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) It is uploaded successfully in this path /my/new/path/media/, but when I try to get in the LMS, it is showing a 404 error. Second solution:- As par scorm xblock, We can change to default location by give the path in below code. XBLOCK_SETTINGS["ScormXBlock"] = { "LOCATION": "/my/new/path/media/",} I have added the code in comman.py and scormxblock.py, But it is not working.

Hosting multiple sub domains on the same windows 10 server running django application
I need to host multiple sites with subdomains all pointing to the same windows10 server. virtual hosts for different sub-domains points to different WSGI files. Venv activation is added in wsgi file. The issue happening is first Django settings file which is invoked is applied to all sub-domains. eg. company1.example.com -> /company1_wsgi.py -> company1_settings.py company2.example.com -> /company2_wsgi.py -> company2_settings.py Now, company1_settings is applied for both company1.example.com and company2.example.com.

Django ORM extract weekday as string from queryset
What I'm trying to do is annotate a queryset with the weekday strings ("monday", "tuesday" etc). I understand how to get the int values: queryset = queryset.annotate( weekday_int=ExtractWeekDay("date"), ) But I'm having trouble getting the string values themselves. I've tried using an ExpressionWrapper, but F objects don't seem to play well with Date objects. I'm using postgres as my underlying database but can't find a related lookup_name for the generic Extract. -

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?

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.

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? -

I found how to refresh the token, but it gives File "/mnt/s/github/nascentapp/app/booking/management/commands/sendmail.py", line 17, in handle new_token = self.get_token(user=booking_user, provider='google-oauth2') File "/mnt/s/github/nascentapp/app/booking/management/commands/sendmail.py", line 28, in get_token social.refresh_token(strategy) File "/home/sander/.local/share/virtualenvs/app-YMrBBUv3/lib/python3.6/site-packages/social_core/storage.py", line 58, in refresh_token response = backend.refresh_token(token, *args, **kwargs) File "/home/sander/.local/share/virtualenvs/app-YMrBBUv3/lib/python3.6/site-packages/social_core/backends/oauth.py", line 438, in refresh_token request = self.request(url, **request_args) File "/home/sander/.local/share/virtualenvs/app-YMrBBUv3/lib/python3.6/site-packages/social_core/backends/base.py", line 234, in request response.raise_for_status() File "/home/sander/.local/share/virtualenvs/app-YMrBBUv3/lib/python3.6/site-packages/requests/models.py", line 941, in raise_for_status raise HTTPError(http_error_msg, response=self) requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://accounts.google.com/o/oauth2/token Here is some of my code def get_token(self, user, provider): social = user.social_auth.get(provider=provider) print('This is social of user: ', social) if (social.extra_data['auth_time'] + social.extra_data['expires']) <= int(time.time()): print('\n Token is out of date \n') strategy = load_strategy() social.refresh_token(strategy) return social.extra_data['access_token'] in my settings file: AUTHENTICATION_BACKENDS = ( 'social_core.backends.open_id.OpenIdAuth', # for Google authentication 'social_core.backends.google.GoogleOpenId', # for Google authentication 'social_core.backends.google.GoogleOAuth2', # for Google authentication 'django.contrib.auth.backends.ModelBackend', ) SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = os.environ.get('DJANGO_SOCIAL_AUTH_GOOGLE_OAUTH2_KEY') # Paste CLient Key SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = os.environ.get('DJANGO_SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET') # Paste Secret Key SOCIAL_AUTH_GOOGLE_OAUTH2_SCOPE = [ 'https://www.googleapis.com/auth/calendar.readonly', 'https://www.googleapis.com/auth/calendar.events' ]
