    <p>I am trying to set up as has_and_belongs_to_many relationship in my rails application, between an Employee model and a NetworkDrive model.</p> <p>In employee.rb I specified</p> <pre><code>has_and_belongs_to_many :network_drives&lt;/code&gt; </code></pre> <p>and in network_drive.rb...</p> <pre><code>has_and_belongs_to_many :employee&lt;/code&gt; </code></pre> <p>However, it seems to be generating model attributes like ":network_drife_ids" instead of ":network_drive_ids", which is giving me errors like</p> <p><code>uninitialized constant Employee::NetworkDrife</code></p> <p>which is accurate, considering the model is called NetworkDrive, not NetworkDrife.</p> <p>Sorry if this is a repeat question, but I wasn't sure how to search for this problem. I tried several solutions provided by questions about HABTM relationships on here, but to no avail.</p> <p>Update: Here's the whole error, after trying to change it to as has_many :through relationship.</p> <pre><code>NameError: uninitialized constant EmployeeItRequest::EmployeeItRequestDrife from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/inheritance.rb:111:in `compute_type' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/reflection.rb:172:in `klass' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/reflection.rb:216:in `association_primary_key' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/associations/has_many_association.rb:104:in `foreign_key_present?' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/associations/association.rb:165:in `find_target?' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/associations/collection_association.rb:332:in `load_target' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/associations/collection_proxy.rb:44:in `load_target' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/associations/collection_proxy.rb:87:in `method_missing' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/railties-3.2.7/lib/rails/commands/console.rb:47:in `start' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/railties-3.2.7/lib/rails/commands/console.rb:8:in `start' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/railties-3.2.7/lib/rails/commands.rb:41:in `&lt;top (required)&gt;' from script/rails:6:in `require' from script/rails:6:in `&lt;main&gt;' </code></pre> <p>Update: Result of NetworkDrive.tableize</p> <pre><code>NoMethodError: undefined method `tableize' for #&lt;Class:0x0000000229fef8&gt; from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/activerecord-3.2.7/lib/active_record/dynamic_matchers.rb:50:in `method_missing' from (irb):1 from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/railties-3.2.7/lib/rails/commands/console.rb:47:in `start' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/railties-3.2.7/lib/rails/commands/console.rb:8:in `start' from /usr/local/rvm/gems/ruby-1.9.2-p320/gems/railties-3.2.7/lib/rails/commands.rb:41:in `&lt;top (required)&gt;' from script/rails:6:in `require' from script/rails:6:in `&lt;main&gt;' </code></pre>

    3. COboth ends of the relationship should be plural - `HABTM :employees`. Don't know if that'd do what you're seeing or not, but it'll definitely break somewhere.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
