gem devise how to add comment created user email?

Question

I am using gem devise for creating users profile Each user can create a comment. I need to add the user name beside each comment something like this <%= @comment.us

Answer 1

You could do it the other way around, in your show method:

@comments = Comment.all

in your show view:

<% @comments.each do |comment| %>
  <%= comment.text %>
  <%= comment.user.name %>
<% end %>

Since your question is not really clear I'll specifiy that if you want to show just the comments posted by the user:

def show
  user_id = User.find(params[:id]).id
  @comments = Comment.where(user_id: user_id)
end
