    <p>I don't really know if I understood your question correctly, but I'll post my answer anyway.</p> <p>I would make a function:</p> <pre><code>def simplified_conditions conds, prms, perform_and_on_hashes = false conds.each do |h| h.each do |method_name, symbols_array| symbols_array.each do |symb| return false unless prms[symb].send method_name end end return true unless perform_and_on_hashes end return true end </code></pre> <p>And pass it a conditions structure that looks like so:</p> <pre><code>[ { 'boolean_function_name' =&gt; [:array,:of,:symbols], 'another_function_name' =&gt; [:array,:of,:symbols], 'another_function_name' =&gt; [:array,:of,:symbols] }, { 'boolean_function_name' =&gt; [:array,:of,:symbols], 'another_function_name' =&gt; [:array,:of,:symbols], 'another_function_name' =&gt; [:array,:of,:symbols] }, { 'boolean_function_name' =&gt; [:array,:of,:symbols], 'another_function_name' =&gt; [:array,:of,:symbols], 'another_function_name' =&gt; [:array,:of,:symbols] } ] </code></pre> <p>So in your sample conditions, the array will look like:</p> <pre><code>conds = [ { 'present?' =&gt; [:a], 'nil?' =&gt; [:b] }, { 'present?' =&gt; [:a], 'nil?' =&gt; [:c] }, { 'present?' =&gt; [:a], 'nil?' =&gt; [:e] }, { 'present?' =&gt; [:b], 'nil?' =&gt; [:c] }, { 'present?' =&gt; [:b], 'nil?' =&gt; [:d] } ] # And then to call it: final_boolean_result = simplified_conditions(conds, params, false) </code></pre> <p>This will return true if any of the lines in your example is true. I you want ALL of them to be true, simply change the last parameter to <code>true</code>.</p> <p>If I misunderstood your question, please leave a comment.</p>

Guidance
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.
