    <p>So I have the following models:</p> <ul> <li>User</li> <li>Business</li> <li>Coupons</li> <li>Deals</li> <li>Redeemable</li> <li>owner</li> </ul> <p>I am using the owner model to associate various other models such as business coupons deals and redeemable to the user model.</p> <p>The redeemable model is used because I want to generate a unique code for each user that uses a coupon/deal in order to limit one per user as well as the amount in total.</p> <p>I suppose maybe I don't need two models for coupon and deal and I just need one because a deal is more like a special type of coupon.</p> <p>So heres the models after a revision:</p> <pre><code>Business has_many :owners, :as =&gt; :ownable, :dependent =&gt; :destroy has_many :coupons, :dependent =&gt; :destroy Coupon belongs_to :business has_many :redeems # also has a special column for denoting weather it's a # normal coupon or a daily deal kind of coupon Redeem belongs_to :coupon has_one :owner, :as =&gt; :ownable, :dependent =&gt; :destroy Owner belongs_to :user belongs_to :ownable, :polymorphic =&gt; true </code></pre> <p>and for the user model I am just totally lost but here's what I want in pseudo code edit just for all those who may have same problem here's how i set up the user model</p> <pre><code>User has_many :owners has_many :businesses, :through =&gt; :owners, :source =&gt; business, :source_type =&gt; 'Business' has_many :redeems, :through =&gt; :owners, :source=&gt; :redeem, :source_type =&gt; 'Redeem' has_many :coupons, :through =&gt; :redeems, :source =&gt; :coupon, :source_type =&gt; 'Coupon' </code></pre> <p>I just don't understand how to associate the coupons with the User model because I did a polymorphic association for owning things.</p>

    1. COConsidering that redeemable is an adjective, that would place it as a property of an object or a column of a table. As a verb (redeem) it would be represented by an an association. You have it as an entity (object), so something is off here. Perhaps you could describe the process that you are trying to model?

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.
