Examples:

Faker::Types.character #=> "n"

Returns:

def character
  sample(CHARACTERS)
end

.complex_rb_hash(legacy_number = NOT_GIVEN, number: 1) ⇒ Hash

Produces a random complex hash with random keys and values where the values may include other hashes and arrays.

Examples:

Faker::Types.complex_rb_hash #=> {user: {first: "bob", last: "marley"}}
Faker::Types.complex_rb_hash(number: 1) #=> {user: {first: "bob", last: "marley"}}
Faker::Types.complex_rb_hash(number: 2) #=> {user: {first: "bob", last: "marley"}, son: ["damien", "marley"]}

Parameters:

  • number (Integer) (defaults to: 1) —

    Specifies the number of key-value pairs.

Returns:

  • (Hash)

.rb_array(legacy_len = NOT_GIVEN, len: 1) ⇒ Array

Produces a random array.

Examples:

Faker::Types.rb_array #=> ["a"]
Faker::Types.rb_array(len: 4) #=> ["a", 1, 2, "bob"]

Parameters:
