Instance Method Details

#attr_configurable(*args, &block) ⇒ Object

Creates a group readable and writeable attributes that can be set by a URI query parameter sharing the same name, a property of a URI or a default value. The value of this attribute will be transformed by invoking the given block, if one has been provided.

  opts = args.last.is_a?(Hash) ? args.pop : {}
  args.each do |attr_name|

  end
end

#attr_configurable_arr(*args, &block) ⇒ Object

Creates a group readable and writeable attributes that can be set by a URI query parameter sharing the same name, a property of a URI or a default value. The value of this attribute will be transformed by invoking the given block, if one has been provided. If the attributes created by this method are assigned a value that is not an Array, the value will be wrapped in an array.

end

#attr_configurable_class(*args, &block) ⇒ Object

Creates a group readable and writeable attributes that can be set by a URI query parameter sharing the same name, a property of a URI or a default value. The value of this attribute will be transformed by invoking the given block, if one has been provided. The attributes created by this method will be treated as though they were created with #attr_configurable_single and will also be converted into Class or Module objects.

end

#attr_configurable_single(*args, &block) ⇒ Object

Creates a group readable and writeable attributes that can be set by a URI query parameter sharing the same name, a property of a URI or a default value. The value of this attribute will be transformed by invoking the given block, if one has been provided. If the attributes created by this method are assigned an Array, only the first element will be used as their value.

#attr_configurable_str(*args, &block) ⇒ Object

Creates a group readable and writeable attributes that can be set by a URI query parameter sharing the same name, a property of a URI or a default value. The value of this attribute will be transformed by invoking the given block, if one has been provided. The attributes created by this method will be treated as though they were created with #attr_configurable_single and will also be converted into Strings.
