title: Create object instance of a class having its name in string variable
body: <p>I don't know the thing I am asking is available or not but I just want to know if it exists and how it works. So here is my question:</p>
  
  <blockquote>
    <p>I have 2-3 custom model class of my own. For example, Customer,
    Employee and Product. Now I have class name in a string. and based on
    the class name coming in a string, I have to create its object and
    return to a VIEW. How could I achieve this?</p>

  <p>I know a option of <code>IF ELSE</code> statement but I want to try a better,"<strong>Dynamic</strong>" way...</p>
