A stylistic note:  I believe that most or all of your eval/exec uses could 
be done with getattr and setattr instead, which are in the language for 
precisely those situations in which the name of an attribute is in a 
runtime string.  To my mind, this would be simpler and better style.

I believe this is valueIs = getattr(self.model, parsed.name)

>        methodCall = "self.model." + parsed.name +"(" + parsed.value + ")"

I believe this is getattr(self.model, parsed.name)(parsed.value).


>        exec("self.model." + parsed.name + "=" + parsed.value)

I believe this is setattr(self.model, parsed.name, parsed.value).

and so on.
