Ok guys this will be long so feel free to skip it ;) (But please dont) I have a nut that I need help soving. We have a model called ProductItem. I need this model to be able to have different attributes depending on which main attribute it has. So I was thinking of using Jquery/ajax to open choices depending on the choices you make to a dropp down list or something simular. I was thinking to make a model = attribute1 and an attribute2 then depending on what you choose in attribute1 you get a list of attribute2's to choose from/add. The problem I am facing is building a model for attribute1 that has many relationships with attribute2 will ressult in a "shitload" of db requests. Thankfull for any advice / suggestions. If I get this correctly the ProductItem model will have an/or many attribute1`which again has multiple `attribute2. Another way would be to make one main attribute with a "shitload" of boleen fields and just check the the ones that match. Or be "dirty" and add all the attributes to the ProductItem model and expose them as you make choises, but how is adding fields and migrations in production ?

Ever tried MongoDB?

Then u use that id to query the product item in MongoDB

why do you like to make things complex.

Took me a while to learn But RDBMS really isn't designed for items with variable attributes

Hello guys can anyone tell me where to learn django i am new in this.☹️☹️

True but I’ve heard bad rumors about django and mongodb. And django offers too much when it comes to models, just with this particular framework and it’s orm, i have not yet seen any use of mongo, a couple of null fields won’t harm nobody.

hey i want to make E - learning website with online exam test features. can i make this on django.

if yes then which moduls i need to learn to solve this problem

ok thank bro

You're right. But what if it wasn'a a couple of null fields, but you have a whole product catalogue of 20 different types?

Hey, I am using drf to make an API. I am displaying the list of users using ListAPIView. I want to pass some extra data ( I mean adding context, while returning data to user) how to do it ??

somthing like this ?

yup, you mean inside view instead ?

if I don't go wrong, you can make another serializer of 'user count' and add to your list serializer

I am following this link to get the combined data from the two different models https://medium.freecodecamp.org/nested-relationships-in-serializers-for-onetoone-fields-in-django-rest-framework-bdb4720d81e6

class UserAccessSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('username', 'pk') read_only_fields = ('pk',) class ProfileSerializer(serializers.ModelSerializer): user = UserAccessSerializer(required=True) class Meta: model = models.Profile fields = ('user', 'userid', 'user_requset_role')

These are my model definations

this is my code, I am not sure why I am getting this error: Got AttributeError when attempting to get a value for field user on serializer ProfileSerializer. The serializer field might be named incorrectly and not match any attribute or key on the User instance. Original exception text was: 'User' object has no attribute 'user'.

Hey guys, I deployed to heroku but it isn't going live . Any help?

Hi you need to add a dynos in your heroku settings
