need some help. can someone tell me what’s wrong with my code and why .
Hi @je22,
Could you please copy/paste in your code for the file that’s throwing the error? It’s not the one you posted, since there’s no belongs_to anywhere in that file.
hi zystvan
here are all the files i’va worked on but i don’t see any belong_to,in one of them. maybe i should change my glasses
tags_controller :
class TagsController < ApplicationController
def index
@tags = Tag.all
end
def show
@tag = Tag.find(params[:id])
@destinations = @tag.destinations
end
end
route.rb :
Rails.application.routes.draw do
get '/tags' => 'tags#index'
get '/tags/:id' => 'tags#show', as: :tag
end
index.html :
<div class="header">
<div class="container">
<img src="http://s3.amazonaws.com/codecademy-content/courses/learn-rails/img/logo-1tm.svg" width="80">
<h1>BokenjiKan</h1>
</div>
</div>
<div class="tags">
<div class="container">
<div class="cards row">
<div class="cards row">
<% @tags.each do |t| %>
<div class="card col-xs-4">
<%= image_tag t.image %>
<h2> <%= t.title %> </h2>
</div>
<% end %>
</div> <!--
To do: Loop through tags and display each one with this HTML
<div class="card col-xs-4">
tag's image goes here
<h2> tag's title goes here </h2>
</div>
-->
</div>
</div>
</div>
and finally show.html.erb :
<div class="header">
<div class="container">
<img src="http://s3.amazonaws.com/codecademy-content/courses/learn-rails/img/logo-1tm.svg" width="80">
<h1>BokenjiKan</h1>
</div>
</div>
<div class="tag">
<div class="container">
<h2 class="tag-title"> <%= tag.title %> </h2>
<div class="cards row">
<% @destinations.each do |t| %>
<div class="card col-xs-4">
<%= t.image %>
<h2> <%= t.name %> </h2>
<p> <%= t.description %> </p>
</div>
<% end %>
</div>
</div>
thank you for your help
by the way here is the link to this lesson. hope this wil be helpfull ?
@je22 OK, I think that there are two separate problems here, so we’ll try to fix them one by one. Could you copy/paste in tho code you have for app/models/tags.rb and app/models/destinations.rb? I’m guessing that the problem is in one of those.
If neither of those files has “belongs_to” in it, you can enter this in the terminal:
$ grep -r "belongs_to"
and look at the files it shows, to see if any of those are ones you’ve modified, and if they are you can show me those files instead 
hi Zystvan
here are the file you ask for :
tags.rb :
class Tag < ActiveRecord::Base
end
class Tag < ActiveRecord::Base
has_many :destinations
end
and the other one destinations.rb :
class Destination < ActiveRecord::Base
end
belongs_to :tag
in fact there is a “belong_to” in this one and i don’t know why !
@je22 Try putting your end on the very last line, so that destinations.rb looks like this instead:
class Destination < ActiveRecord::Base
belongs_to :tag
end
And that should fix that error so we can move on to the next problem
hi Zystvan
in fact i surely was to tired not to see the “end” was’nt in an appropriate place and that solved the "belond_to’ problem

now i’ve got a wrong number of argument error message in the app/tags/show.html.erdb
hi zystvan sorry to answer you so lately but i’ve been a little bit seek
here is the code you ask for :
<div class="header">
<div class="container">
<img src="http://s3.amazonaws.com/codecademy-content/courses/learn-rails/img/logo-1tm.svg" width="80">
<h1>BokenjiKan</h1>
</div>
</div>
<div class="tag">
<div class="container">
<h2 class="tag-title"> <%= tag.title %> </h2>
<div class="cards row">
<% @destinations.each do |t| %>
<div class="card col-xs-4">
<%= t.image %>
<h2> <%= t.name %> </h2>
<p> <%= t.description %> </p>
</div>
<% end %>
</div>
</div>
@je22 Try replacing tag.title with @tag.title, and see if that does it.
Otherwise, if you’re still getting the same error message, is there a line it highlights?
ok that was it thanks a lot
