How to create new tables in Database for each day in Django
I have an understanding question because I'm thinking about how I should manage my data in Django or the database. It is a table with about 2000 lines per day and 8 columns. I would like to store all daily data of the last 10 years into the database and add new data every day. It is a good idea to create a database table for each day. In Django, a table is created for each model, but it is not intended for the inventor to create 5000 models in Django. Is it the only way I use raw SQL to create the tables? Or is there a way I have not discovered in the documentation? -
compress image size before saving in database in javascript?
Is there any way to compress or reduce image size during uploading at client side and before saving in database in javascript? There are some options i have seen but they are using PHP i want that in javascript with HTML. I am using Django framework so it will be easier to implement in JS rather than in PHP. When we are uploading that image it should be compressed automatically and then it will be saved in database. -
ImportError raised trying to import a function

Service Worker does not fire upon fetch and return cached data

Django query: how to apply the mode calculation in the query?
In a previous question I was asking about how to do a complex query in Django. Here is my example model: class Foo(models.Model): name = models.CharField(max_length=50) type = models.CharField(max_length=100, blank=True) foo_value = models.CharField(max_length=14, blank=True) time_event = models.DateTimeField(blank=True) # ... and many many other fields Now in my previous question @BearBrown answered me with using the When .. then expression to control my query. Now I need something more. I need to calculate the mode (most repeated value) of the quarter of the month in the time_event field. Manually, I do it like this: - I manually iterate over all records for the same user. - Get the day using q['event_time'].day - Define quarters using quarts = range(1, 31, 7) - Then, append the calculated quarters to a list month_quarts.append(quarter if quarter <= 4 else 4) - Then get the mode value for this specific user qm = mode(month_quarts) Is there a way to automate this mode calculation function in the When .. then expression instead of manually iterating through all records for every user and calculating it? -
How to access extra data sent with POST request in Django Rest Framework serializer
I'm trying to send an extra array with a POST request that creates a group. POST /groups/ { "name": “New Group“, "users_to_invite": [ 1, 2, 6 ] } I'm using Django Rest Framework's ListCreateAPIView to handle the request: class GroupListView(ListCreateAPIView): queryset = Group.objects.all() def get_serializer(self, *args, **kwargs): kwargs['context'] = self.get_serializer_context() # Use a dedicated serializer to inspect the field with users to invite if self.request.method == 'POST': return GroupCreateSerializer(*args, **kwargs) return GroupSerializer(*args, **kwargs) I want to get to the contents of the users_to_invite array in a serializer to create invitation objects. However, I'm unable to do so because somehow the array is not there when I'm accessing it in the serializer. class GroupCreateSerializer(ModelSerializer): def create(self, validated_data): # Get user ids to invite # !! It fails here !! invitations_data = validated_data.pop('users_to_invite') # TODO: Iterate over ids and create invitations # Create a group group = Group.objects.create(**validated_data) return group class Meta: model = Group fields = ('id', 'name', ) Array is not there so naturally I'm getting the error: File "...my_api/serializers.py", line 303, in create invitations_data = validated_data.pop('users_to_invite') KeyError: 'users_to_invite' How can I make the array to appear there? Modifying the model does not sound like a good idea because I … -
