Re: what is the difference?

Hi,

First of all - the examples you are giving can't be correct.

z = Model.objects.get(name=x)

will only return 1 object - and will raise an exception if you get more than one result. So in this case z should be an instance of the model Model.

z = <Object: 1> 

and cannot be [<Object: 1>, <Object: 2>]

When querying the second query you should get a QuerySet as a result, because you have filtered. 

So from : z = Model.objects.filter(name=x) you would get:

[<Object: 1>]

in other words a list of 1 object (because the name was unique). Then your code:

for x in z:
   print(x.id)

should definitely work. 

If your want to do the query and just get one result (because you are querying with the unique name), you can write:

z = Model.objects.filter(name=x).first()

This way z will also be None if there isn't any object that has the name = x.

Regards,

Andréas

[<Object: 1>, <Object: 2>]

and

[[<Object: 1>, <Object: 2>]]

1st came from z = Model.objects.get(name=x)

This returns the object name


2nd came from z = Model.objects.filter(name=x)

The 2nd method when you look for the id 

for x in z:
   print(x.id)

fails with 
'QuerySet' object has no attribute 'id'

also tried

zz = Model.objects.filter(name=x)
z = z.id

same result

I understand that get just gets the first singular match but so should filter as in this instance name is unique
