Don't think it is good idea to do so.
In this case dict_variables['modelname'].objects.filter(status_listurl='u')
you call method objects on string. but string doesn't have such method. you
should use smth like modelclass = globals()['modelname']
for example:
>>> import os
>>> o=globals()['os'] # or locals() depending on context
>>> o
<module 'os' from 'C:\Python25\lib\os.pyc'>
to import by passing a string try help(__import__)
