I cannot supmit the comments for multi posts in Django
I have a feed and in this feed have posts and each post have comments, Now I can submit a comment for just the first post but when I try to come to the second or third post and submit comment this error rais ValueError: The view videos.views.add_comment_post didn't return an HttpResponse object.

Docker-compose, django and pipfile.lock - docker can't install packages from pipfile.lock
After some searches in the internet, I come to ask for your help. I would like to create a server with django in the backend and react in the frontend. Although I do not have any problems with the frontend, I cannot properly initialise the backend with docker-compose.

Django Rest framework, retrieve data from database with no related model
I am trying to create a REST API for a database that already exists. The problem is that the data on the database are refreshed from a bash script every hour, so there is no related model for these data. So I am working on creating a GET request on Django so to be able to retrieve the data. Currently I am using an APIView like this: class RetrieveData(APIView): def get(self, request): conn = psycopg2.connect(host=..., database=..., user=..., password=..., port=...) cur = conn.cursor() cur.execute(f'Select * from ....') fetched_data = cur.fetchone() cur.close() res_list = [x for x in fetched_data] json_res_data = {"id": res_list[0], "date": res_list[1], "data": res_list[2]} conn.close() The problem that I have is that connecting on the database every time so to retrieve the data and then return the response is quite slow ~ 2sec/request. Also I am afraid in case of many requests made at the same time, how is that going to work. So the question that I have is if there is any suggestions or any solutions that you propose. -
I am getting a 'permission denied' error when I try to upload files directly to my Django app on Elastic beanstalk with a newly attached volume
I recently deployed a django app to AWS elastic beanstalk. I have used boto3 to enable storing my videos to the s3 bucket. But i need to convert the video files on the local storage before storing it on S3. I use moviepy and ffmpeg to convert the videos. But when I try to upload the files, I get an error "[errno 32] broken pipe moviepy error: ffmpeg encountered the following error while writing file /home/ec2-user/mount_point/u3files/temp_files/21editedtemp_mpy_wvf_snd.mp3: /home/ec2-user/mount_point/u3files/temp_files/21editedtemp_mpy_wvf_snd.mp3: permission denied". I have already chmod 777 on the root folder of the volume and 'u3files' folder inside the local storage. Is there anything I am missing? How do I solve this? I am new to AWS beanstalk and any help would be appreciated. Thanks. -
how to prefetch directly unrelated fields in graphene django
I started using graphene and there are some thing I have not yet understood well for instance, when using nodes the I have this query { orders { edges { node { id fromUser { id username userprofile{ image id } } toUser { id username userprofile{ image id } } } } } } it is very nice because it allows me to fetch profile and get image for a given profile that is related to a user even though user is foreign key in profile, however it is expensive in terms of queries that has to be done in order to get profile for every user my models looks like this class Order(models.Model): from_user = models.ForeignKey(User, on_delete=models.PROTECT, related_name="from_user") to_user = models.ForeignKey(User, on_delete=models.PROTECT, related_name="to_user") .... class UserProfile(models.Model): user = models.OneToOneField(User,on_delete=models.CASCADE) image = models.ImageField(null=True) and my query as of now Order.objects.select_related('from_user','to_user').filter( Q(from_user=user) | Q(to_user=user) ).order_by("-id") return orders will appreciate if anyone could help me know how I can prefetch profile for both from_user and to_user in that case coz it really is expensive fetching the profile -

So my django/react project works find on my local machine but when I deploy it to pythonanywhere.com I get this message below when I try to go to any of the routes ("/", "/factors", "/chart"). I have seen some other posts on how to tell django where to go to if the url corresponds to the frontend React routes (since that is the only place the routes are defined) but I'm unsure what to put in the views.

list inside dictionary wont appear when sent to a put request

Dynamic site elements not displaying after Django database change
So I recently changed databases on a Django-based website from SQLite to MySQL. I did it via dumping the data from the SQLite into a json file and then migrating it to the new MySQL db.

How to serialize an array of objects in Django
I am working with Django and REST Framework and I am trying to create a get function for one of my Views and running into an error. The basic idea is that I am creating a market which can have multiple shops. For each shop there can be many products. So, I am trying to query all those products which exist in one shop. Once I get all those products I want to send it to my serializer which will finally return it as a JSON object. I have been able to make it work for one product but it does not work for an array of products.

Manually caching HTML pages in Django CMS
I'm trying o build an addon for Django CMS that would save a static copy of a site on disk. I have set up the addon and I have a button on the toolbar that triggers a view that goes through all the pages, renders them and saves them. The general setup seems to work fine, but when I check the static HTML files created, they are missing the content of the plugins in each page. My approach was to reuse the Django CMS details view, which is the one used to render the pages as a response to the browser's HTTP requests. I suspect the problem might have something to do with the request object passed to it, since the one I have available in my view is actually the admin page request, not the one I want to render. But I have tried to overwrite some of its values, I have also checked Django CMS GitHub to see how the request was used but I still can't manage to make the plugin's content show up. This is my view function: from django.contrib.auth.models import AnonymousUser from cms.views import details from cms.models.pagemodel import Page def create_html_files(request): cms_pages = Page.objects.filter(publication_date__isnull=False) request.user … -
ImproperlyConfigured: Error loading psycopg2 module: No module named 'psycopg2._psycopg' zappa
I am using zappa to deploy backend to the AWS Lambda. It worked well, until I decided to use PostgreSQL. I added it in the settings like this: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': config('DATABASE_NAME'), 'USER': config('DATABASE_USER'), 'PASSWORD': config('DATABASE_PASSWORD'), 'HOST': config('DATABASE_HOST'), 'PORT': '5432' } } I am using AWS RDS. I installed psycopg2-binary and also psycopg2 (versions 2.8.6), but the issue remains. The python version is 3.8.
