Generate scaffold which references a model who refers another model

Question

I have 2 existing models: post and post_reply, the latter referring to the former. I want to create another model using scaffolding which references post_reply. What should be the name of my column name in the generate command to refer post_reply correctly?
Using rails 5.

Answer 1

You say "references" and by that I assume you mean belongs_to

rails generate scaffold new_model post_reply:references

The column name generated will be post_reply_id and you can just create the column directly.

rails generate scaffold new_model post_reply_id:integer

If you do the latter, you'll need to add the belongs_to line manually to NewModel

The integer column can actually be called anything you want but calling it post_reply_id is expected and respects the advice of 'convention over configuration'.
