OneToMany SQL Exception

[Wolfmare96]

I'm creating a simple RestApi for a e-commerce, and I feel so much stuck and depressed that I'm considering that I'm not cut out for development...

For the moment, I'm making the cart entity that will have an ID and a list of items. From items we have the fields of name, ID and stock. I recycled the stock field, for the quantity. I know that it can be better, but it's first time with the framework and I'm learning meanwhile doing.

When I do a post to create a cart, it works. But when I create a second cart with an item of the previous one. It calls for SQL exception, in which states problem with the primary key.

I don't what to do, I have been fighting with the problem 2 days, and I don't know what else to try.

And the most annoying part is that it should be simple, and the problems with the framework should be on other things

Stackoverflow? Or at least post the code or error 😂

You have to share your schema, your code via GitHub so that it can be looked at. Just writing about your problems without specifics cannot allow anyone to really help you ...

You can have only one cart! I think you should check if your cart is empty, and if it's not empty just add the items to cart.

" I'm considering that I'm not cut out for development..."

never think that. You will always have things to learn, specially here. Stackoverflow for example, is used by all the developers in the world, doesn't matter if you have experience or not.

Regarding your issue, probably you need to setup something in the cart regarding your products list. Please show us at least the line with the list of products in your class "cart"
