Body
This is using Rails 2.2.2 I have a model that uses the acts_as_flaggable plugin, and on the page I use to display an instance of the model, I list any flags that the model has. When I start my Rails dev server(mongrel) using the standard script/server command, load the page holding the following code, it loads fine: <pre><code><% @object.flags.each do |flag| %> <tr> <td><%= time_ago_in_words(flag.created_at) %> ago</td> <td><%= flag.flag %></td> <td><%= link_to flag.user.login, user_path(flag.user) %></td> </tr> <% end %> </code></pre> If I reload the page(and on any subsequent views), I get the following NoMethodError error: <pre><code>You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.include? </code></pre> If I restart the dev server, the page loads fine again one time then subsequent views yield the same strangeness. If I remove the line: <pre><code><td><%= link_to flag.user.login, user_path(flag.user) %></td> </code></pre> The page loads fine and will reload fine from then on. It seems as if the flaggable plugin is having trouble with the user model for some reason, but then why does it work on the first page load? I also can't seem to repeat the problem using script/console. --EDIT-- Adding in the stack trace per request. Under normal circumstances I usually can handle this particular error, but the part that is confusing me is why it works the first time. Here is the error page/trace as it appears to me, I hope this proves to be helpful: <pre><code>NoMethodError in Admin#list_flagged Showing app/views/admin/list_flagged.html.erb where line #65 raised: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.include?

"Cache-Control"=>"no-cache"} </code></pre> --EDIT #2-- Well, I've "fixed" it. Despite the fact that there is a belongs_to relation in the Flag model, I added the following code to the Flag model from acts_as_flaggable: <pre><code>def user User.find(self.user_id) end </code></pre> This code does allow the page to load without error whether it is the first time on the page or the Nth. I would have added this as an answer, but I don't know that I am satisfied with this.

Guidance

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.
