    copied!<p>I'm trying to create a basic Rails CRUD app against a CouchDB database hosted on Cloudant. </p> <p>I'm using <a href="https://github.com/langalex/couch_potato" rel="nofollow">couch_potato</a> as my persistence layer and have it connecting properly to my Cloudant database. </p> <p>The issues I'm having is my first model won't see the existing documents in my CouchDB database, <em>unless</em> I add a <code>ruby_class</code> field that equals the name of my model. </p> <p><strong>My simple User model:</strong></p> <pre><code>class User include CouchPotato::Persistence property :id, :type =&gt; Fixnum property :FullName, :type =&gt; String view :all, :key =&gt; :FullName end </code></pre> <p><strong>Sample CouchDB document:</strong></p> <pre><code>{ "_id": 123456, "_rev": "4-b96f36763934ce7c469abbc6fa05aaf3", "ORGID": 400638, "MyOrgToken": "19fc342d50f9d8df1ecd5e5404f5e5f7", "FullName": "Jane Doe", "Phone": "555-555-5555", "MemberNumber": 123456, "Email": "jane@example.com", "LoginPWHash": "14a3ccc0e6a50135ef391608e786f4e8" } </code></pre> <p>Now, when I use my <code>all</code> view from the rails console, I don't get any results back:</p> <pre><code>1.9.2-p290 :002 &gt; CouchPotato.database.view User.all =&gt; [] </code></pre> <p>If I add the field and value <code>"ruby_class: User"</code> to the above CouchDB document, then I get results back in the console:</p> <pre><code>1.9.2-p290 :003 &gt; CouchPotato.database.view User.all =&gt; [#&lt;User _id: "123456", _rev: "4-b96f36763934ce7c469abbc6fa05aaf3", created_at: nil, updated_at: nil, id: "123456", FullName: "Jane Doe"&gt;] </code></pre> <p>I'm working with a large set of customer data, and I don't want to write any scripts to add the <code>ruby_class</code> field to every document (and I may not be permitted to). </p> <p>How can I get my app to recognize these existing CouchDB documents without adding the <code>ruby_class</code> field?</p> <p>I couldn't find much documentation for couch_potato and couchrest that shows how to work with existing CouchDB databases. Most of the examples assume you're starting your project and database(s) from scratch.</p> <p>Thanks,</p> <p>/floatnspace</p>
