Alias for camelize

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

Examples

  "active_record".camelize #=> "ActiveRecord"
  "active_record".camelize(:lower) #=> "activeRecord"
  "active_record/errors".camelize #=> "ActiveRecord::Errors"
  "active_record/errors".camelize(:lower) #=> "activeRecord::Errors"

# File lib/inactive_support/core_ext/string/inflections.rb, line 46
        def camelize(first_letter = :upper)
          case first_letter
            when :upper then Inflector.camelize(self, true)
            when :lower then Inflector.camelize(self, false)
          end
        end

Create a class name from a 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.)

Examples

  "egg_and_hams".classify #=> "EggAndHam"
  "post".classify #=> "Post"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 114
        def classify
          Inflector.classify(self)
        end

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.

Examples

  "Module".constantize #=> Module
  "Class".constantize #=> Class

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 147
        def constantize
          Inflector.constantize(self)
        end

Replaces underscores with dashes in the string.

Example

  "puni_puni" #=> "puni-puni"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 83
        def dasherize
          Inflector.dasherize(self)
        end

Removes the module part from the expression in the string

Examples

  "ActiveRecord::CoreExtensions::String::Inflections".demodulize #=> "Inflections"
  "Inflections".demodulize #=> "Inflections"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 92
        def demodulize
          Inflector.demodulize(self)
        end

Creates a foreign key name from a class name. separate_class_name_and_id_with_underscore sets whether the method should put ‘_’ between the name and ‘id’.

Examples

  "Message".foreign_key #=> "message_id"
  "Message".foreign_key(false) #=> "messageid"
  "Admin::Post".foreign_key #=> "post_id"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 136
        def foreign_key(separate_class_name_and_id_with_underscore = true)
          Inflector.foreign_key(self, separate_class_name_and_id_with_underscore)
        end

Capitalizes the first word and turns underscores into spaces and strips _id. Like titleize, this is meant for creating pretty output.

Examples

  "employee_salary" #=> "Employee salary"
  "author_id" #=> "Author"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 124
        def humanize
          Inflector.humanize(self)
        end

Returns the plural form of the word in the string.

Examples

  "post".pluralize #=> "posts"
  "octopus".pluralize #=> "octopi"
  "sheep".pluralize #=> "sheep"
  "words".pluralize #=> "words"
  "the blue mailman".pluralize #=> "the blue mailmen"
  "CamelOctopus".pluralize #=> "CamelOctopi"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 19
        def pluralize
          Inflector.pluralize(self)
        end

The reverse of pluralize, returns the singular form of a word in a string.

Examples

  "posts".singularize #=> "post"
  "octopi".singularize #=> "octopus"
  "sheep".singluarize #=> "sheep"
  "word".singluarize #=> "word"
  "the blue mailmen".singularize #=> "the blue mailman"
  "CamelOctopi".singularize #=> "CamelOctopus"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 32
        def singularize
          Inflector.singularize(self)
        end

Create the name of a table like Rails does for models to table names. This method uses the pluralize method on the last word in the string.

Examples

  "RawScaledScorer".tableize #=> "raw_scaled_scorers"
  "egg_and_ham".tableize #=> "egg_and_hams"
  "fancyCategory".tableize #=> "fancy_categories"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 103
        def tableize
          Inflector.tableize(self)
        end

Alias for titleize

Capitalizes all the words and replaces some characters in the string to create a nicer looking title. Titleize is meant for creating pretty output. It is not used in the Rails internals.

titleize is also aliased as as titlecase

Examples

  "man from the boondocks".titleize #=> "Man From The Boondocks"
  "x-men: the last stand".titleize #=> "X Men: The Last Stand"

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 63
        def titleize
          Inflector.titleize(self)
        end

The reverse of camelize. Makes an underscored form from the expression in the string.

Changes ’::’ to ’/’ to convert namespaces to paths.

Examples

  "ActiveRecord".underscore #=> "active_record"
  "ActiveRecord::Errors".underscore #=> active_record/errors

[Source]

# File lib/inactive_support/core_ext/string/inflections.rb, line 75
        def underscore
          Inflector.underscore(self)
        end
