[Documentation Issue]

Page Name: datastore-queries
Release: 0.10.1

This python code (a close copy of one of the pieces in the tutorials), yields an error:

from gcloud import datastore
ds_client = datastore.Client(project='mikes-playground-project')
#key = client.key('Person')#
#entity = datastore.Entity(key=key)
#entity['name'] = 'Your name'
#entity['age'] = 25
#client.put(entity)
#print("And Out..")
query = datastore.Query('Person')
query.add_filter('age', '<', '100')
list(query.fetch(1), client=ds_client) #even if you remove client=...

results in the following error

> basilyan@instance-3:~$ python ds.py
> Traceback (most recent call last):
>   File "ds.py", line 12, in <module>
>     query = datastore.Query('Person')

Using Python 2.7 and gcloud (0.10.1)

@mbasilyan Thanks for filing. The issue is that

query = datastore.Query('Person')

should be

query = datastore.Query(kind='Person')

Which tutorial are you referring to?

[dhermes]

Ahhh I found the error. The docs up to 0.10.1 have the error but it is fixed in latest

[dhermes]

Was fixed in #1517.

Thanks for noticing and taking the time to let us know!

[mbasilyan]

Thanks @dhermes

Setting kind='Person' gives me this code:

from gcloud import datastore
ds_client = datastore.Client(project='mikes-playground-project')
key = ds_client.key('Person')
entity = datastore.Entity(key=key)
entity['name'] = 'test'
entity['age'] = 25
ds_client.put(entity)
print("And Out..")
query = datastore.Query(kind='Person')
query.add_filter('name', '=', 'test')
x = query.fetch(1)

Running it, gives me this error:

> And Out..
> Traceback (most recent call last):
>   File "ds.py", line 12, in <module>
>     query = datastore.Query(kind='Person')
> TypeError: __init__() takes at least 2 arguments (2 given)
> basilyan@instance-3:~$

Ahh got it. It's more that it should've been client.query(kind=...) rather than datastore.Client(kind=...)

Fixed it now. Thanks!

from gcloud import datastore
ds_client = datastore.Client(project='mikes-playground-project')
key = ds_client.key('Person')
entity = datastore.Entity(key=key)
entity['name'] = 'test'
entity['age'] = 25
ds_client.put(entity)
print("And Out..")
query = ds_client.query(kind='Person')
query.add_filter('name', '=', 'test')
x = query.fetch(1)

Sorry, my snippet was wrong, but the latest docs are correct:

query = ds_client.query(kind='Person')

Jinx!
