If Policy
When a given collection uses a named_filter, you can use If to make items
matching a given filter use one policy, and items not matched by a given filter
use a different policy.
Constructor params
- collection_name: string - due to implementation complexities, you have to pass the collection name to this policy. It's the name of the collection that this policy is attached to.
- special_filter_name: string - which filter from the collection to use when segmenting the items
- when_true: Policy - Policy to use when the special filter matches a given item
- when_false: Policy - Policy to use when the special filter doesn't match a given Item
Example
The below app will make non-negative number public, but negative numbers will
only be visible to logged-in users.
class extends App { collections = { ...App.BaseCollections, numbers: new (class extends Collection { fields = { number: new FieldTypes.Int(), number_str: new FieldTypes.Text(), }; named_filters = { positive: new Matches("numbers", { number: { ">": 0 }, }), negative: new Matches("numbers", { number: { "<": 0 }, }), }; defaultPolicy = new Policies.If( "numbers", "negative", Policies.LoggedIn, Policies.Public, ); })(), }; };
