In Velocity I have a variable called $url which contains the following string: [ContentId(2.7507), ContentId(2.7508), ContentId(1.44551)]
I want to check if that string contains the substring 1.44551.
This is the code I've written so far, but for some reason it's returning False:
#if($url.contains("1.44551"))
<p>The article content id is 1.44551</p>
#else
<p>The article content id isn't 1.44551</p>
#end
I would expect this to be returning True, as the 1.44551 substring is present in the $url variable. Please can someone tell me where I'm going wrong?

The easiest and most effective way to see if a string contains a substring is by using if ... in statements, which return True if the substring is detected. Alternatively, by using the find() function, it's possible to get the index that a substring starts at, or -1 if Python can't find the substring.
You can use stringUtil: #set($parts = $stringUtil. split($string, "/")) $parts.
The contains() method checks whether a string contains a sequence of characters. Returns true if the characters exist and false if not.
Velocity is a Java-based templating engine. It's an open source web framework designed to be used as a view component in the MVC architecture, and it provides an alternative to some existing technologies such as JSP. Velocity can be used to generate XML files, SQL, PostScript and most other text-based formats.
Velocity holds values as Objects in context map.
If you want to execute String method, add toString to make sure you execute on String the contains method:
#if($url.toString().contains("1.44551"))
<p>The article content id is 1.44551</p>
#else
<p>The article content id isn't 1.44551</p>
#end
