Parsequery Gives 0 Objects When Querying From Local Datastore Even After Successfully Pinning

I am using the Android SDK of parse.com and have arrived at a peculiar problem. From a fragment's onCreate: Fetch an object from the server. Pin it. Fetch an object from the loc

Solution 1:

Parse doesn't seem to support ACLs on local datastore. So the easiest way to get around this issue is to do ignoreACLs() on the query -- assuming you do have roles/acls setup correctly on the server side, so whatever you have pinned locally should be OK permission-wise already.

Solution 2:

I found the issue. It seems to be more like a bug with the Android SDK of parse. I narrowed it down to an issue with retrieving pinned objects with special ACLs using the Android SDK.

Initially, the object had the ACL such that only the role 'Admin' (that I created) can read and write. The funny thing is that the user with which I was testing the pinning and querying was an 'Admin'! But, when I changed the ACL such that public can read but only Admin can write, the problem was resolved!

My theory was that querying the local datastore behaves like a public query, no matter what role the user that is making the query has! But if any other theory explaining this would be appreciated. Luckily, in my case I need public read access, but this bug can be a huge downfall for some who need to have read access restricting ACLs! Hopefully parse.com will fix this issue soon. This is quite a big issue! I am surprised that I couldn't find a question regarding this issue.

Solution 3:

Yeah so basically you have to set ACL for current user and pin it before you pin the chat group.

ParseACLacl=newParseACL();
acl.setReadAccess(ParseUser.getCurrentUser(), true);
ParseUser.getCurrentUser().setACL(acl);
ParseUser.getCurrentUser().pinInBackground();
