How to take url param and use it as filter for data
I'm just getting into Python/Django and I've managed to build an API to return all items in a DB table but I want to be able to filter the data through a parameter used in the GET request. I want to be able to return data based on the 'Author' id that is a number I've built this based on the documentation: View.py class AllTweets(APIView): permission_classes = [IsOwnerOrReadOnly] def get(self, request): tweets = Tweet.objects.all() data = TweetSerializer(tweets, many=True).data return Response(data) URLs.py urlpatterns = [ path('', include('djoser.urls')), path('', include('djoser.urls.authtoken')), path('restricted/', restricted), path('create/', TweetAPIView.as_view(), name="tweet-create"), path('list/', AllTweets.as_view(), name="tweet-list") ] Models.py class Tweet(models.Model): author = models.ForeignKey( User, on_delete=models.CASCADE, related_name="tweets") tweet_text = models.CharField(max_length=200) created_on = models.DateTimeField(auto_now_add=True) def __str__(self): return self.tweet_text -

django - ValueError: <model> needs to have a value for field "id" before this many-to-many relationship can be used
Say, I have a model Post which has many to many relation to built-in User for liked_post class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='posts') like = models.ManyToManyField(User, related_name='liked_posts') All is going nice for the logic, I can add/remove the like relation nicely. But when I introduce additional attribute save for saved_post, like this: class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='posts') like = models.ManyToManyField(User, related_name='liked_posts') save = models.ManyToManyField(User, related_name='saved_posts') It always throw an error below when I'm trying to even instantiate the Post model. ValueError: "<Post: Post object (None)>" needs to have a value for field "id" before this many-to-many relationship can be used. Note that I did not even modify/add any custom save() method. The error just pops up even when I'm trying to call p = Post.object.create(). From what I have known, I need to save Post first before adding any like or save relation. But I got error even from saving a Post instance. -
Is http stream actually implemented by http chunk?
I did a test to learn http stream and http chunk. Here is a django view func def test_stream(request): def func(): for i in range(0, 100): yield i return StreamingHttpResponse(func) Then I use curl to access the code. There is no chunk headers. Also a tcpdump analysis shows it is not a http chunk either. So questions are: if http stream is not chunk. then what it is implemented? how do i return chunk reponse in Django -

Django resolve() doesn't resolve with i18n urls
Django: 2.2.7 Python 3.6.8 I have initiated a project using cookiecutter-django template. After that I translated to 4 languages and I included i18n for urls so that depending on accessing each one, I get it translated in a different language. For example: http://localhost:8000/en/home => Gets the home page in english http://localhost:8000/es/home => Gets the home page in spanish The thing is that I started to apply TDD and made a test first: myapp/tests.py: from django.test import TestCase from django.urls import resolve from django_sftpbrowser.views import browse_page # Create your tests here. class BrowsePageTest(TestCase): def test_browse_url_resolves_to_browse_page(self): found = resolve('browse/') # Tried also en/browse/ self.assertEqual(found.func, browse_page) But, although the URLs seem to work in the browser, when running this test I find this error: ====================================================================== ERROR: test_browse_url_resolves_to_browse_page (django_sftpbrowser.tests.BrowsePageTest) ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/madtyn/PycharmProjects/corelli/django_sftpbrowser/tests.py", line 9, in test_browse_url_resolves_to_browse_page found = resolve('browse/') File "/home/madtyn/venvs/corelli/lib/python3.6/site-packages/django/urls/base.py", line 24, in resolve return get_resolver(urlconf).resolve(path) File "/home/madtyn/venvs/corelli/lib/python3.6/site-packages/django/urls/resolvers.py", line 568, in resolve raise Resolver404({'path': path}) django.urls.exceptions.Resolver404: {'path': 'browse/'} My urls are these below.

Implementing follower system using a many to many field through a model
I am adding a following/follower system and I made it a foreign field in my profile model.

How to pass a value from an onChange event to a Django url template?
It seems like what I would like to do should be a simple thing, but I haven't been able to figure it out. I'm using Django 2.06 with Geodjango. I have a simple UI with a dropdown menu. In order to respond to changes in dropdown selections, I have an event listener for onChange events. The idea is to get the e.target.value from the event and make it the value of a query parameter in a URL. So in index.html I have: const property_name = document.getElementsByName('properties')[0]; property_name.addEventListener('change', (e) => { zones = new L.GeoJSON.AJAX("{% url 'zones' property=e.target.value %}", { ... In urls.py I have: url(r'^zones_data/$', zone_datasets2, name='zones'), and in views.py I have: def zone_datasets2(request): property = request.GET.get('property', '') When I try to load my webpage, the error I get is: NoReverseMatch at / Reverse for 'zones' with keyword arguments '{'property': ''}' not found. 1 pattern(s) tried: ['zones_data/$'] Can someone tell me what I'm doing wrong? How can I pass the dropdown menu selection to the URL and how can I define a url pattern that works with this? Thank you. -
Condition to check uploaded files before displaying them
I've got a simple Django model as described below: class UploadedFile(models.Model): module = models.ForeignKey(Module, on_delete=models.CASCADE, null=False) uploaded_file = models.FileField(upload_to=file_upload_directory, validators=[ValidateUploadFileSize]) and I handle upload of files via a class based view which works fine. When users upload files it successfully gets uploaded to the server directory. When the user accesses the file via an anchor tag, the URL looks something like this http://127.0.0.1:8000/media/444131/module/24.pdf. What I want to know is how do I do some validation before opening the file based on some condition that decides whether to display or not display the file? Let me expand on this. In the URL http://127.0.0.1:8000/media/444131/, 444131 is an ID for an object in the database. I want to be able to check if the current user belongs to that object. If the user exists in that object, then I want to display the file, otherwise, I'd like to do some kind of redirect or not show the file. This is to prevent any random person from being able to brute force the urls or prevent accidental file discovery. I've been thinking of using middlewares but I'm not entirely sure if that is the right way to do it? I've also tried to match … -
Why my testing function in the Django returns status code 404 while in chrome browser the page shows correctly?
I am a Django novice and I am trying to proceed with a simple application testing. One of my tests fails but I cannot find the reason why. I added several prints to clear what was going on. The test function that fails is: def test_board_topics_view_contains_navigation_links(self): board_topics_url = reverse('board_topics', kwargs={'pk': 1}) print("49: board_topic = " + board_topics_url) homepage_url = reverse('home') print("51: homepage_url = " + homepage_url) new_topic_url = reverse('new_topic', kwargs={'pk': 1}) print("53: new_topic_url = " + new_topic_url) response = self.client.get(board_topics_url) print("*****************\n") print(response) print('********************\n') self.assertContains(response, 'href="{0}"'.format(homepage_url)) self.assertContains(response, 'href="{0}"'.format(new_topic_url)) Then I can see the output: Creating test database for alias 'default'...

Which are the valid values and directories for django's translation.activate?
To the dreaded stackoverflow community: I'm struggling with this issue for month now: I try to pass a valid language code to translation.activate(language_code) for the following languages: en-us, en-gb, pt-pt, pt-br and zh-hans. I have two configurations: my macbook with gettext 0.20.1 and a debian 10 server with gettext 0.19.8.1-9. For the locale directory I have tried locale/en_gb-style (d_) and locale/en-gb-style paths (d-). For the language_code I tried both en_gb (l_) and en-gb (l-) and en-GB (l-caps) style. The results so far: on my mac: works: d_l-, d_l_, d_l-caps, d-l-caps on my mac: fails: d-l_, d-l- on debian 10: works for zh-hans only: d_l_ on debian 10: fails: d_l-, d-l- Using br instead of pt_br works but it gets picked up as "breton" by rosetta and using gb instead of en_gb does not get picked up at all. What is the solution to this pickle? I use django 2.2. -
Object Detection Django Rest API Deployment on Google Cloud Platform or Google ML Engine
I have developed Django API which accepts images from livefeed camera using in the form of base64 as request. Then, In API this image is converted into numpy arrays to pass to machine learning model i.e object detection using tensorflow object API. Response is simple text of detected objects. I need GPU based cloud instance where i can deploy this application for fast processing to achieve real time results. I have searched a lot but such resource found. I believe google cloud console (instances) can be connected to live API but I am not sure how exactly. Thanks
