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?

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 -
