Instance Method Details
#camelize(first_letter = :upper) ⇒ Object Also known as: camelcase
By default, camelize
converts strings to UpperCamelCase. If the argument to camelize is set to :lower
then camelize produces lowerCamelCase.
camelize
will also convert '/' to '::' which is useful for converting paths to namespaces.
"active_record".camelize # => "ActiveRecord" "active_record".camelize(:lower) # => "activeRecord" "active_record/errors".camelize # => "ActiveRecord::Errors" "active_record/errors".camelize(:lower) # => "activeRecord::Errors"
#classify ⇒ Object
Create a class name from a plural table name like Rails does for table names to models. Note that this returns a string and not a class. (To convert to an actual class follow classify
with constantize
.)
"egg_and_hams".classify # => "EggAndHam" "posts".classify # => "Post"
Singular names are not handled correctly.
"business".classify # => "Busines"
#colorize(args) ⇒ Object
colorize(:red)
#constantize ⇒ Object
constantize
tries to find a declared constant with the name specified in the string. It raises a NameError when the name is not in CamelCase or is not initialized.
"Module".constantize # => Module "Class".constantize # => Class
#dasherize ⇒ Object
Replaces underscores with dashes in the string.
#humanize(options = {}) ⇒ Object
Capitalizes the first word, turns underscores into spaces, and strips a trailing '_id' if present.
#pluralize ⇒ Object
Returns the plural form of the word in the string.
"post".pluralize # => "posts" "octopus".pluralize # => "octopi" "sheep".pluralize # => "sheep" "words".pluralize # => "words" "the blue mailman".pluralize # => "the blue mailmen" "CamelOctopus".pluralize # => "CamelOctopi"
#singularize ⇒ Object
Returns the singular form of the word in the string.
"posts".singularize # => "post" "octopi".singularize # => "octopus" "sheep".singularize # => "sheep" "words".singularize # => "word" "the blue mailmen".singularize # => "the blue mailman" "CamelOctopi".singularize # => "CamelOctopus"
#underscore ⇒ Object
The reverse of camelize
. Makes an underscored, lowercase form from the expression in the string.
underscore
will also change '::' to '/' to convert namespaces to paths.
"ActiveRecord".underscore # => "active_record" "ActiveRecord::Errors".underscore # => active_record/errors
