What is the best way to implement 1:N communication in a RoR project?

Question

Ruby on Rails

Hello!
One news can be in several categories (have several IDs of different categories).
To do this, you need to use the third table - categories_for_news - with the fields: id, news_id, category_id.
At this stage, everything is clear. The question is this: "What is the best way to organize this in a RoR project?"
I mean, is it necessary to create a model for this case. In general, I am new to RoR, and I would like to ask you for a piece of code with this implementation as an example, as well as accompanying comments.
Thank you in advance.

Answer 1

You need to create 2 models Categories and News and organize a many-to-many relationship. How to do this is written in the documentation with examples: Has_many
:through
relationship Has_and_belongs_to_many relationship
Choosing between has_many :through and has_and_belongs_to_many
