Rails嵌套注释而不使用gem

Question

I am building a simple blog and I do like to implement reddit-like nested replies. So far I have Posts and Comments.

I have tried to look for guide or examples but all of the examples are either using gems or are outdated. Can you suggest me how to approach the problem ?

I started with editing routes.rb

resources :comments do
   resources :comments
end

Comment model:

 has_many :comments

I am not sure how to modify the create function in the controller and how to extend the comments/_form.html

And what are the remaining steps ?

Answer 1

This is doable via a ccepts_nested_attributes_for . Check out the documentation on complex forms to get an idea of how to use it.

Answer 2

I can refer you to a good article on this subject. Well, if you need to ask any questions after reading, just leave a comment.
