Summary

Functions

camelize(value)

camelize(value, atom)
humanize(atom)

Functions

camelize(value) 
camelize(String.t) :: String.t

Converts String to camel case.

Takes an optional :lower option to return lowerCamelCase.

Examples 

iex> Phoenix.Naming.camelize("my_app")
"MyApp"

iex> Phoenix.Naming.camelize("my_app", :lower)
"myApp"

In general, camelize can be thought of as the reverse of underscore, however, in some cases formatting may be lost:

Phoenix.Naming.underscore "SAPExample"  #=> "sap_example"
Phoenix.Naming.camelize   "sap_example" #=> "SapExample"
camelize(value, atom) 
camelize(String.t, :lower) :: String.t
humanize(atom) 
humanize(atom | String.t) :: String.t

Converts an attribute/form field into its humanize version.

iex> Phoenix.Naming.humanize(:username)
"Username"
iex> Phoenix.Naming.humanize(:created_at)
"Created at"
iex> Phoenix.Naming.humanize("user_id")
"User"
resource_name(alias, suffix \\ "") 
resource_name(String.Chars.t, String.t) :: String.t

Extracts the resource name from an alias.

Examples 

iex> Phoenix.Naming.resource_name(MyApp.User)
"user"

iex> Phoenix.Naming.resource_name(MyApp.UserView, "View")
"user"
underscore(value) 
underscore(String.t) :: String.t

Converts String to underscore case.

Examples 

iex> Phoenix.Naming.underscore("MyApp")
"my_app"

In general, underscore can be thought of as the reverse of camelize, however, in some cases formatting may be lost:

Phoenix.Naming.underscore "SAPExample"  #=> "sap_example"
Phoenix.Naming.camelize   "sap_example" #=> "SapExample"
unsuffix(value, suffix) 
unsuffix(String.t, String.t) :: String.t

Removes the given suffix from the name if it exists.

Examples 

iex> Phoenix.Naming.unsuffix("MyApp.User", "View")
"MyApp.User"

iex> Phoenix.Naming.unsuffix("MyApp.UserView", "View")
"MyApp.User"
