title: jinja2: convert string to dict object?
body: <p>I have a json string stored in the database and when this is pulled out and shown on the template it is a string. I want to convert this into a dict object so I can access the contents directly.</p>
  
  <p>string = "{'a':1, 'b':3}"</p>
  
  <p>{{ obj }} ---> string "{'a':1, 'b':3}"</p>
  
  <p>{{ obj.b }} ---> I want to access it like an object.</p>
