Missing ACL logic

[devrishik]

ACL logic is not present, to do without ACL one needs to create a user column in tables to maintain relations, it is much harder to implements groups/roles and for every query to the Parse api i need to implement a filter.

I overcame this shortcoming by writing cloud code for Parse and setting the ACL on afterSave for object creation. If ACL logic can be implemented in Angular-Parse, I believe the tasks will be much easier then.
