    <p>I am trying to do a simple test with Neo4j.rb using Neo4j::Rails::Models thats tag a single thing, then performs a query to find the thing again using the tag.</p> <p>So data is essentially looks like this, with a single tag and a single thing:</p> <p>(tag)-tags->(thing)</p> <p>When I run the query using my script I don't get any results but if I use the webadmin console that comes with neo4j to run the equivalent query I get result as execpted.</p> <p>I just can't figure out what I am doing wrong but I think it must be the way I am using the Neo4j.query block.</p> <p>This is what I run from the console which gives the correct result.</p> <pre><code>neo4j-sh (0)$ START tag=node:Tag_exact(text='tag') MATCH tag-[:tags]-&gt;thing RETURN thing; ==&gt; +------------------------------------------+ ==&gt; | thing | ==&gt; +------------------------------------------+ ==&gt; | Node[1]{name:"thing",_classname:"Thing"} | ==&gt; +------------------------------------------+ ==&gt; 1 row ==&gt; 197 ms ==&gt; neo4j-sh (0)$ </code></pre> <p>This is the test script which gives an equivalent cypher query but doesn't return any results.</p> <pre><code>require 'rubygems' require 'neo4j' require 'fileutils' # Create a new database each time Neo4j::Config[:storage_path] = "test_neo" FileUtils.rm_rf(Neo4j::Config[:storage_path]) # Models class Tag &lt; Neo4j::Rails::Model property :text, :index =&gt; :exact end class Thing &lt; Neo4j::Rails::Model property :name end # Data thing = Thing.new(:name =&gt; "thing") thing.save tag = Tag.new(:text =&gt; "tag") tag.outgoing(:tags) &lt;&lt; thing tag.save # Query puts Neo4j::Cypher.query { lookup("Tag_exact", "text", "tag").outgoing(:tags).as(:thing) }.to_s # START v1=node:Tag_exact(text="tag") MATCH (v1)-[:`tags`]-&gt;(thing) RETURN thing results = Neo4j.query do lookup("Tag_exact", "text", "tag").outgoing(:tags).as(:thing) end results.each do |result| p result["thing"] end # nil, I want to get the name of thing back here </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.
