    <p>I want to write a method that loops through all the params to make sure they aren't all blank.</p> <p>My params are:</p> <pre><code>params[:search][:company] params[:search][:phone] params[:search][:city] params[:search][:state] params[:search][:email] </code></pre> <p>I have this method:</p> <pre><code>def all_blank_check(params) array=[] params[:search].each do |key, value| array &lt;&lt; value unless value.blank? end if array.count &lt; 1 return true else return false end end </code></pre> <p>But when I try something like <code>all_blank_check(params)</code> I get the following error:</p> <pre><code>NoMethodError (undefined method `all_blank_check' for #&lt;Class:0x108c08830&gt;): </code></pre> <p>Do I need to convert the params to an array first? Can't I perform a method on params?</p> <p>Edit - full source: <pre> def index @customers = Customer.search_search(params) end</p> <code> def self.search_search(params) search_field = [] search_values = [] array = [] test = '' if !params[:search].nil? &amp;&amp; all_blank_check(params[:search] if !params[:search].nil? &amp;&amp; !params[:search][:company].blank? search_field &lt;&lt; 'customers.company LIKE ?' search_values &lt;&lt; "%#{params[:search][:company]}%" end if !params[:search].nil? &amp;&amp; !params[:search][:city].blank? search_field &lt;&lt; 'customers.city = ?' search_values &lt;&lt; "#{params[:search][:city]}" end if !params[:search].nil? &amp;&amp; !params[:search][:phone].blank? search_field &lt;&lt; 'customers.phone_1 = ?' search_values &lt;&lt; "%#{params[:search][:phone]}%" end conditions = [search_field.join(' AND ')] + search_values Customer.where(conditions).includes(:customer_contacts).limit(10) end end def all_blank_check(params) params[:search].each do |key, value| array &lt;&lt; value unless value.blank? end if array.count &lt; 1 return false end if array.count &gt; 1 return true end end </code></pre> <p></p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
