ReQL command: not

Command syntax

bool.not() → bool
not(bool) → bool

Description

Compute the logical inverse (not) of an expression.

not can be called either via method chaining, immediately after an expression that evaluates as a boolean value, or by passing the expression as a parameter to not. All values that are not false or nil will be converted to true.

Example: Not true is false.

r(true).not().run(conn)
r.not(true).run(conn)

These evaluate to false.

Example: Return all the users that do not have a “flag” field.

r.table('users').filter { |user|
    user.has_fields('flag').not()
}.run(conn)

Example: As above, but prefix-style.

r.table('users').filter { |user|
    r.not(user.has_fields('flag'))
}.run(conn)
