.bothify(string) ⇒ Object

# File 'lib/faker.rb', line 36

def bothify(string)
  letterify(numerify(string))
end

.fetch(key) ⇒ Object

Helper for the common approach of grabbing a translation with an array of values and selecting one of them.

# File 'lib/faker.rb', line 42

def fetch(key)
  translate("faker.#{key}").sample
end

.flexible(key) ⇒ Object

# File 'lib/faker.rb', line 67

def flexible(key)
  @flexible_key = key
end

.letterify(letter_string) ⇒ Object

# File 'lib/faker.rb', line 32

def letterify(letter_string)
  letter_string.gsub(/\?/) { ('A'..'Z').to_a.sample }
end

.method_missing(m, *args, &block) ⇒ Object

You can add whatever you want to the locale file, and it will get caught here. E.g., in your locale file, create a

name:
  girls_name: ["Alice", "Cheryl", "Tatiana"]

Then you can call Faker::Name.girls_name and it will act like #first_name

# File 'lib/faker.rb', line 76

def method_missing(m, *args, &block)
  # Use the alternate form of translate to get a nil rather than a "missing translation" string
  if translation = translate(:faker)[@flexible_key][m]
    translation.respond_to?(:sample) ? translation.sample : translation
  else
    super
  end
end

.numerify(number_string) ⇒ Object

make sure numerify results doesn’t start with a zero

# File 'lib/faker.rb', line 28

def numerify(number_string)
  number_string.sub(/#/) { (rand(9)+1).to_s }.gsub(/#/) { rand(10).to_s }
end

.parse(key) ⇒ Object

Load formatted strings from the locale, “parsing” them into method calls that can be used to generate a formatted translation: e.g., “#first_name #last_name”.

# File 'lib/faker.rb', line 49

def parse(key)
  fetch(key).scan(/#\{([A-Za-z]+\.)?([^\}]+)\}([^#]+)?/).map {|kls, meth, etc| (kls ? Faker.const_get(kls.chop) : self).send(meth) + etc.to_s }.join
end

.translate(*args) ⇒ Object

Call I18n.translate with our configured locale if no locale is specified

  I18n.translate(*(args.push(opts)))
rescue
  # Super-simple fallback -- fallback to en if the
  # translation was missing.  If the translation isn't
  # in en either, then it will raise again.
  I18n.translate(*(args.push(opts.merge(:locale => :en))))
