    <p>I'm upgrading an application from Rails 2 to Rails 3. Apparently, calling <code>render()</code> now returns <code>ActionView::OutputBuffer</code> and not <code>String</code>. I need to pass the results of <code>render()</code> to <code>URI.escape()</code>, and this fails with exception...</p> <h3>Here is my brief testing in the console</h3> <pre><code>ob = ActionView::OutputBuffer.new("test test") URI.escape(ob) `NoMethodError: undefined method 'each_byte' for nil:NilClass`. from /opt/ruby19/lib/ruby/1.9.1/uri/common.rb:307:in `block in escape' from ..../ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/core_ext/string/output_safety.rb:160:in `gsub' from ..../ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/core_ext/string/output_safety.rb:160:in `gsub' from /opt/ruby19/lib/ruby/1.9.1/uri/common.rb:304:in `escape' from /opt/ruby19/lib/ruby/1.9.1/uri/common.rb:623:in `escape' </code></pre> <p>Moreover, calling to_s on OutputBuffer returns same OutputBuffer class, so I cannot even convert this buffer into a honest string?</p> <pre><code>ob.to_s.class ActionView::OutputBuffer </code></pre> <p>Of course, calling URI.escape("test test") returns "test%20test" as expected, so this is not URI problem.</p> <p>Environment: </p> <ul> <li>ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]</li> <li>Rails 3.2.1</li> </ul> <p>My question is: <strong>Why does this happen and how can I work around this issue?</strong></p> <p><strong>Update:</strong> Apparently, using <code>'' + ob</code> as a form of <code>ob.to_s</code> converts OutputBuffer to String, which effectively works around the problem... But my question '<em>why does this happen</em>' still remains, e.g. is this a bug, should I report it, or I'm doing something wrong?</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.
