Question

Storing the current_user in a string after they submit a comment

<%= f.text_field :commenter, :value => current_user, :readonly => "readonly" %>

So i can get the email in my comment view

<td><%= comment.commenter.email %></td>

but i’m getting

undefined method `email' for "#<User:0x7f26828>":String

Anyway to fix this?

Answer 1

You want to store whole object in html input? That shouldn’t work, because you strore only string #<User:0x7f26828>. You should use relation between model:

class Commenter < ActiveRecord::Base
    has_many :comments
end

class Comment < ActiveRecord::Base
    belongs_to :commenter
end

In form:

<%= f.text_field :commenter_id, :value => current_user.id, :readonly => "readonly" %>

And add commenter_id column to Comment model. Then when you create just set commenter_id and everything should work.
