It might be that you need a deep copy of the collection. AFAIK are assignments to array just &quot;shallow&quot; that means if you have a collection [1,2,3]<br />
<br />
and you add it to a hash<br />
ht.Add(key =&gt; #someKey, value =&gt; #collection)<br />
and you change a collection thereafter the &nbsp;hash table collection gets influenced also.<br />
<br />
So in this case you probably want to use clone<br />
<br />
If not please provide code that we can use.<br />

Hello,<br />
&nbsp; I'm trying to find a very abstract and &quot;one size fits all&quot; for converting nested active record results to nested hashes. &nbsp; It's easy, to do one level deep as such:<br />
&nbsp;<br />

<pre><code id="code-10-28135792-1">results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title]}]</code></pre>
<br />
But, when I try to add another collection to the mix, it completely borks and the results_to_hash only returns an empty hash IE:<br />
<br />

<pre><code id="code-10-28135792-2">results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title, c.categories]}]</code></pre>
<br />
Ultimately, I'd like it to be smart enough to detect if a model object contains a collection (IE: object.class.reflect_on_al<wbr />l_associat<wbr />ions), and automatically convert those to hashes.<br />
<br />
<br />
Any ideas?<br />
<br />
Thanks,<br />
Eric

Creating nested hash from nested active record results

Ruby is an open-source dynamic object-oriented interpreted language that supports multiple programming frameworks including functional, object oriented and imperative. It also has a dynamic type system and automatic memory management. Ruby focuses on simplicity and productivity. Ruby's market share spiked due to Ruby on Rails, a model-view-controller (MVC) framework for building web applications.

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.
