]

When you want to select a nested resource.

Takes a default set of params and a custom set of params and prefers the second set. Useful when you're constructing reusable functions that make similar queries.

Takes PostgrestParams and returns the parameters as a list of (Key, Value) strings.

Takes PostgrestParams and returns a query string such as foo=eq.bar&baz=is.true

A constructor for an individual postgrest parameter.

    , resource "actors" allAttributes
    ]
, nestedParam "actors" <| limit 10
, nestedParam "actors" <| offset 2
]

Used to indicate you need a column to be less than or equal than a certain value.

Used to indicate you need a column to be not equal to a certain value.

Negate a condition.

When you need a column value to be true

When you need a column value to be false

When a value needs to be null

ILIKE operator (use * in place of %)

param "text" <| ilike "foo*bar"

LIKE operator (use * in place of %)

param "text" <| like "foo*bar"

Normalize a string into a postgrest value.

Normalize an int into a postgrest value.

This is available if you need it, but more likely you'll want to use inList.

order (desc "name")

Used in combination with order to sort results ascending.
