and validate post_id? But I don’t know how do this:)

Answer 1

Send post_id as a parameter

<%= link_to "new request", new_request_path(post_id: @post.id) %>

Find post in requests_controller’s new action.

def new
  @post = Post.find(params[:post_id])
  @request = Request.new
end

Use it like below in new request form

<%= f.hidden_field, :post_id, value: @post.id %>
