prod = Product.objects.get(Id=3) prod.images # this sentence get all registries

What if I want to get it for all the products and not just one like your query uses get(id=3)

Images.objects.all()

If you use product.objects.all(), and do a sentence for, you can access to images for each product

Please share the code add to cart product to save the Cart model.

why does command line show "killed" for any command ?

Hey developers

How to use start project in django

If we have a many to many table say product_img like the following how can we query it to know the images each product has? Prod_img P_ID IMG_ID 1 2 1 3 1 4 2 3 2 4

Use.... prefetch_related function..... Read about it... And also read about select_related.

How to use start project in django

If you are new to Django please start from any available book or official docs.

https://docs.djangoproject.com/en/4.1/howto/custom-management-commands/ https://simpleisbetterthancomplex.com/tutorial/2018/08/27/how-to-create-custom-django-management-commands.html Read

If we have a many to many table say product_img like the following how can we query it to know the images each product has? Prod_img P_ID IMG_ID 1 2 1 3 1 4 2 3 2 4

Instead of having many to many .... You should have one to many relation.... That is .... One product can have many images. For such kind of relations we use select_related.... For many to many we use prefetch_related https://docs.djangoproject.com/en/4.1/ref/models/querysets/#prefetch-related

Images.objects.all()

This will only get me the images but I want to get images that each product has with one query. Like in mysql how we would do this is my doing a join between products table and product_img table on P_ID and do the same with images and product_img table to get a result like so: P_ID PRODNAME IMG_ID IMAGE 1 shoe1 2 img1 1 shoe 1 3 img2 1 shoe1 4 img3 2 shoe2 3 img2

I am using a serializer1 in another serializer2 When I access the serializer2 The data of serializer1 comes in ORDEREDdict why?

Actually it's not just product it's a variant of a product I thought I should just simplify the example thats why I said product but it's a variant of a product eg: [shoe, black, 27], [shoe, black, 26] for this type of case the image remains the same of shoe black even tho the size is different therefore an image can belong to many variants and a variant can have multiple images since Im doing something like amazon

Am I being understood?

Ok. Read about prefetch_related examples or use cases. You will got your answer. Instead of asking here.... It will enable you to handle futures queries as well.

I create a home page that you can see all products after choosing a product, you go to another page to choose how much do you want , in this page , I want to show after user enter the quantity if I have or if I don’t and send message sorry we don’t have based on the quantity I put it in the database from the admin page

Its there incase the get method fails the object is created but its not a must you can just use objects.get and object.create separately
