    <p>I have the following code which is running a validation on all snippet content to check the word count against a constant but I keep getting the following error:</p> <pre><code>undefined method `[]' for nil:NilClass Extracted source (around line #36): current_snippets_size = (self.book.get_word_count || 0) + word_count errors.add(:base, "Content size is too big") unless word_count &lt; BOOK_SIZE[book_limit]['per'] &amp;&amp; current_snippets_size &lt; BOOK_SIZE[book_limit]['total'] end </code></pre> <p>Here is the full code from the model (snippet.rb)</p> <pre><code>BOOK_SIZE = { 0 =&gt; {"per" =&gt; 5, "total" =&gt; 50}, 1 =&gt; {"per" =&gt; 6 , "total" =&gt; 60}, 2 =&gt; {"per" =&gt; 7, "total" =&gt; 70} } def size_limit book_limit = self.book.size word_count = self.content.scan(/\w+/).size current_snippets_size = (self.book.get_word_count || 0) + word_count binding.pry errors.add(:base, "Content size is too big") unless word_count &lt; BOOK_SIZE[book_limit]['per'] &amp;&amp; current_snippets_size &lt; BOOK_SIZE[book_limit]['total'] end </code></pre> <p>Because snippets is a child of books, here is the <code>word_count</code> listed in book.rb:</p> <pre><code>def get_word_count @word_count = [] self.snippets.each do |c| @word_count &lt;&lt; c.content.scan(/\w+/).size end @word_count = @word_count.inject(:+) end </code></pre> <p>EDIT: Pry Debug</p> <pre><code> 31: def size_limit =&gt; 32: binding.pry 33: book_limit = self.book.size 34: 35: word_count = self.content.scan(/\w+/).size 36: 37: current_snippets_size = (self.book.get_word_count || 0) + word_count 38: 39: errors.add(:base, "Content size is too big") unless word_count &lt; BOOK_SIZE[book_limit]['per'] &amp;&amp; current_snippets_size &lt; BOOK_SIZE[book_limit]['total'] 40: end [1] pry(#&lt;Snippet&gt;)&gt; p book_limit nil =&gt; nil [2] pry(#&lt;Snippet&gt;)&gt; p word_count nil =&gt; nil [3] pry(#&lt;Snippet&gt;)&gt; errors.any? =&gt; false [4] pry(#&lt;Snippet&gt;)&gt; errors.blank? =&gt; true </code></pre> <p>I tried using PRY but I am still new to the debugging side, some documents describing the best way to walk through PRY debugging would be really useful.</p> <p>Thanks.</p>

    1. CODid you inspect BOOK_SIZE[book_limit]['per'] and BOOK_SIZE[book_limit]['total'] with your PRY debugger?

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).
