How can i get User name in a table where user_id is used as foreign key

I am using Devise gem for user Authentication. User id is as foreign key in article table How can i get writer name through User_id in a view Show_article.html.erb I can access user_id in show_article.htmlerb

I have tried to make a custom function in article controller but could not get the desired output

Solution

  • your Article model should look like this:

    class Article << ActiveRecord::Base
  belongs_to :user
  #....some more lines
end

    your User model should look like this:

    class User << ActiveRecord::Base
  has_many :articles
  #....some more lines
end

    and your show.html.erb should say:

      #....your rest of code
<%= @article.try(:user).try(:name) %>
  #....your rest of code

    This will skip user name if you article doesn't have any user. It looks like your article doesn't have user_id or you haven't defined your relations correctly.
