I have a small model with a 'json' column called details and several hybrid
properties to abstract getting from it safely:
User(Base):
@hybrid_property
def phone_number_2(self):
return self.details.get('phone_num_2')
However when I use this in a query, in the class context, I get an error as
sqlalchemy does not understand the .get method for python dictionaries.
That's all fine as I can define hybrid expressions as such:
@phone_numer_2.expression
def phone_number_2(cls):
return self.details['phone_num_2']
This works fine but the only issue is I have a lot of similar columns I'd
like to pull out and writing the expression every time seems cumbersome. Is
there a convenient way to abstract this in Sqlalchemy? Some way I could
tell sqlalchemy what .get means?
