Rails ERD - Help with model

Hello i have some errors in generating ERD from models.. I guess i have
wrong associations.. please look at it



You’ve deviated from the Rails conventions, which you can do, but then you have to tell ActiveRecord how to handle it. Rails expects model names to have a singular form, and table names to be the plural of that name. For example, if the table name is users, it expects a model named User. If the model name is Product, it’s expecting the table name to be Products.

In your case, you’ve set up products_orders (the plural) as both the model name and the table name. It’s seeing the table name products_orders, which conforms to its expectations, and is expecting a model name ProductsOrder (the singular) which it can’t find.

Thank you it works now
