    <p>In my app, I have a User model and a Project model. A user has_many assignments and each project belongs_to a user. But along with each project having an owner, the user who created it, I would like the owner be able to share it with others (so that the project gets shown on the other users' account along with their own). I imagine having to use has_many :through, and setting up a projects_users table with a user_id and a project_id. And I guess this would be the end result?</p> <pre><code>Project.first.user # The creator of the project =&gt; #&lt;User id: 1, name: 'andrew', etc...&gt; Project.first.users # The users that the creator chose to share it with =&gt; [#&lt;User id: 2 ...&gt;, #&lt;User id: 3 ...&gt;] </code></pre> <p>I've been working on this a bit, and I created a SharedProject model with a user_id and project_id column:</p> <pre><code>class SharedProject &lt; ActiveRecord::Base belongs_to :user belongs_to :project end </code></pre> <p>I would like to call both user.projects and user.shared_projects, but I don't know how I would get shared_projects to return project records instead of records from the shared_projects table. I can't do <code>has_many :projects, :through =&gt; :shared_projects</code> since then I wouldn't be able to return projects that the user has created.</p> <pre><code>class User &lt; ActiveRecord::Base has_many :projects # Calling user.projects returns the projects that user created has_many :shared_projects # How to get user.shared_projects to return project records? end </code></pre>

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.
