What is the best data structure for this sensordata?
I'm currently working on a project to store sensordata in a database using the Django framework. I'm receiving a data object that has 19 data fields, which can be interpreted differently depending on the type of measurement. For the sake of this question, I'm going to simplify the data fields to five fields. The received data looks like the following example: { "data type": 1 "values":[12, 18.4, 14, 15, 1] } The data values can be interpreted depending on the data type. So for example, the lookup table might look something like this: Data type 1: Climate control | field | description | unit | | --- | --- | --- | | 1 | Room temperature | C | | 2 | Desired temperature | C | | 3 | Cooler power percentage | % | | 4 | Valve position | % | | 5 | Power supply | kWh | Each of these data types might have a different interpretation of the given data. The question How would I go about storing this data in the best way possible? Do I: Store the raw values in the database, and define the context of the values in the … -
Alter data in django tables via views.py
I am creating an eCommerce site and need to reduce the stock of products available when a user purchases them. This is done via views.py and without any forms involved. I am currently doing... product = ProductItem.objects.filter(id=4).first() product.quantity_available -= items.get('quantity') product.save() Where items.get('quantity') shows the quantity of the number of items that a user has bought of that product. However, for some reason, this code doesn't seem to work. Is there any error in this? Any help would be greatly appreciated. Thanks! -

How to get count of objects in a ManyToManyField with 'self' / its own model in django?
I'm trying to implement a network where users can follow each other in django like so: > class User(AbstractUser): > followings = models.ManyToManyField('self', related_name='followers', symmetrical=False) So the followings field is going to contain all the users a user is following, and I would also like to be able to access all of the user's followers, thus the related_name. My question is, if I have a user's username, how can I make a query to retrieve that user object, with the annotation of its number of followings and number of followers? Here's what I've tried: data = User.objects.annotate(number_of_followers=Count('followers'), number_of_followings=Count('followings')).get(username=user) It seems alright to me, but somehow it's showing values that doesn't match the real numbers as in the actual database, as I've checked using the django admin app. -

Performance considerations for serializing a related field very often
Suppose I have an API based on the Django Rest Framework. Most Django models used by the application have a reference to the User model (E.g. uploaded_by, updated_by, approvedd_by, etc.). When calling the API to retrieve instances it is often useful to not only know the ID of the user but also the name. However, an ID is often more useful when making comparisons. For example, to check whether a Task was uploaded by you or by another user. I am not sure how to tackle this kind of "pattern" where both the ID and the name representation are useful under different circumstances. I would really appreciate it if someone could explain what would be the best option for performance here. Currently I do the following: TaskSerializer(serializers.ModelSerializer): uploaded_by_name = serializers.StringRelatedField(source='uploaded_by') Meta: model = models.Task fields = '__all__' read_only_fields = ['uploaded_by_name'] While this obviously works, I was wondering whether this is the best solution when considering performance or whether there are other options that I should consider as well. My main concern here is that for almost any call (since all models have user references) the user table must be hit. Another option would be: In my current project, users call … -
How to serialize each foreign key object with different serializer class in django rest framework
