Question

All,

I have strings that represent my model and fields, like this

modelNameStr = 'MyModel'
fieldNameStr = 'modelField'

My model looks like this;

class MyModel(models.Model):
    modelField = ForeignKey( ForeignModel )
    ...

What i want to do is create an instance of MyModel using the string variables, something like

model_instance = modelNameStr.objects.filter(fieldNameStr=ForeignModelInstance)

How can i do this?

Answer 1

model_instance = ContentType.objects.get(app_label=u'someapp', model=modelNameStr).model_class()(**{fieldNameStr: ForeignModelInstance})

Phew! Try saying that five times fast! But make sure you use the appropriate value for app_label.
