Current Limitation

The filter dialog in the data browser currently only allows to filter for fields in the current class. It's not possible to add a filter condition that relates to another class.

Feature / Enhancement Description

Add filter conditions that relate to other classes. Since Parse Dashboard knows the entire schema, it also knows which other classes have a pointer to the currently displayed class; it can use that information to allow for filtering by fields of these related classes.

The filter dialog could be extended with a drop-down for related classes and its fields.

Example Use Case

A user in the _User class may have

• purchases in a Purchase class with a _User pointer field
• transactions in a Transaction class with a _User pointer field

To filter all users who

• made purchases of shoes (in Purchase class)
• with a transaction using a credit card (in Transaction class)

The filter dialog could look like this:
