    <p>I'm using Rails 3 and will_paginate. Pagination works fine in my Posts controller but in my Tags controller I get an error on the second Tag id. Here's the error:</p> <pre><code>TypeError in TagsController#show can't convert Post into Array ... app/controllers/tags_controller.rb:8:in `show' </code></pre> <p>tags_controller.rb#show:</p> <pre><code>def show @tag = ActsAsTaggableOn::Tag.find(params[:id]) @posts = Post.paginate(Post.tagged_with(@tag), :page =&gt; params[:page], :order =&gt; "updated_at DESC") # line 8 respond_with(@posts) end </code></pre> <p>What baffles me is that this code works in the posts controller: </p> <p>def index @posts = Post.paginate :page => params[:page], :order => "updated_at DESC" end</p> <p>My post and tag models include:</p> <pre><code>cattr_reader :per_page @@per_page = 10 </code></pre> <p>Can anyone explain what I'm doing wrong here?</p> <p>EDIT: (full stack trace)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
