Question

How to I return the length of the get_by_id ??

For example I have

query = Model.get_by_id(1)

I tried

if len(query) == 1 and if query.count() == 1 both not working

Answer 1

*Model.get_by_id()* returns only a single object if a single id is passed, it returns a list of objects only when a list of id’s is passed, which means it obvioulsy won’t have len and count.

if you want to check if query is not None, you can simply give

query=Model.get_by_id(1)

if query is not None:

if you want to get a list of objects based on keys, use get:

query = MOdel.get(keys) #here keys is a list of keys

if len(query) == 1  will work now
