character() click to toggle source

Produces a random character from the a-z, 0-9 ranges.

@return [String]

@example

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

@faker.version 1.8.6

# File lib/faker/default/types.rb, line 35
def character
  sample(CHARACTERS)
end
complex_rb_hash(number: 1) click to toggle source

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

@param number [Integer] Specifies the number of key-value pairs. @return [Hash]

@example

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"]}

@faker.version 1.8.6

# File lib/faker/default/types.rb, line 85
def complex_rb_hash(number: 1)
  rb_hash(number: number, type: -> { random_complex_type })
end
random_complex_type() click to toggle source

Produces a random complex type that’s either a String, an Integer, an array or a hash.

@return [String, Integer]

@example

Faker::Types.random_complex_type #=> 1 or "a" or "bob" or {foo: "bar"}

@faker.version 1.8.6

# File lib/faker/default/types.rb, line 137

end
random_type() click to toggle source

Produces a random type that’s either a String or an Integer.

@return [String, Integer]

end
rb_array(len: 1, type: -> { random_type } click to toggle source

Produces a random array.

@param len [Integer] Specifies the number of elements in the array. @return [Array]

@example

Faker::Types.rb_array #=> ["a"]
Faker::Types.rb_array(len: 4) #=> ["a", 1, 2, "bob"]
Faker::Types.rb_array(len: 2, type: -> { Faker::Types.rb_string }) #=> ["cat", "foo"]

def rb_array(len: 1, type: -> { random_type })
  [].tap do |ar|
    len.times do
      ar.push type.is_a?(Proc) ? type.call : type
    end
  end
end
rb_hash(number: 1, type: -> { random_type } click to toggle source

Produces a random hash with random keys and values.

@param number [Integer] Specifies the number of key-value pairs. @return [Hash]

@example

Faker::Types.rb_hash #=> {name: "bob"}
Faker::Types.rb_hash(number: 1) #=> {name: "bob"}

@faker.version 1.8.6

# File lib/faker/default/types.rb, line 64
def rb_hash(number: 1, type: -> { random_type })
  {}.tap do |hsh|
    Lorem.words(number: number * 2).uniq.first(number).each do |s|
      value = type.is_a?(Proc) ? type.call : type
      hsh.merge!(s.to_sym => value)
    end
  end
end
rb_integer(from: 0, to: 100) click to toggle source

Produces a random integer.

@return [Integer]

@example

Faker::Types.rb_integer #=> 1

@faker.version 1.8.6

# File lib/faker/default/types.rb, line 48
def rb_integer(from: 0, to: 100)
  rand(from..to).to_i
end
rb_string(words: 1) click to toggle source

Produces a random String created from word (Faker::Lorem.word)

@return [String]

@example

Faker::Types.rb_string #=> "foobar"

@faker.version 1.8.6

# File lib/faker/default/types.rb, line 19
def rb_string(words: 1)
  resolved_num = resolve(words)
  word_list = translate('faker.lorem.words')
  word_list *= ((resolved_num / word_list.length) + 1)
  sample(word_list, resolved_num).join(' ')
end
