Instance Method Details

#button(name) ⇒ Object

Declares a named button for this form, which is required in order to have this button's name and value sent to the back. This will generate a <button> tag. To use <input type="submit">, #input should be used instead.

Parameters:

  • name (String) —

    The name of the button (used in the name attribute)

def button(name)
  self.add_input_definition(
    Brut::FrontEnd::Forms::ButtonInputDefinition.new(name:)
  )
end

#input(name, attributes = {}) ⇒ Object

Declares an input for this form, to be modeled via an HTML <INPUT> tag.

Parameters:

  • name (String) —

    The name of the input (used in the name attribute)

  • attributes (Hash) (defaults to: {}) —

    Attributes to be used on the tag that represent its contraints. See Brut::FrontEnd::Forms::InputDefinition

  )
end

def inputs_from(other_class)
  if !other_class.respond_to?(:input_definitions)
    raise ArgumentError,"#{other_class} does not respond to #input_definitions - you cannot copy inputs from it"
  end
  other_class.input_definitions.each do |_name,input_definition|
    self.add_input_definition(input_definition)
  end
end

#radio_button_group(name, attributes = {}) ⇒ Object

Declares a radio button group, which will manifest as one or more <input type="radio"> tags that all use the same value for their name attribute. Unlike input or select, this method is declaring one or more actual input tags.

Note that this is not where you would define the possible values for the group. That is done in Components::Inputs::RadioButton.

Parameters:

  • name (String) —

    The name of the group (used in the name attribute)

  • attributes (Hash) (defaults to: {}) —

    Attributes to be used on the tag that represent its contraints. See RadioButtonGroupInputDefinition

def radio_button_group(name,attributes={})
  self.add_input_definition(
    Brut::FrontEnd::Forms::RadioButtonGroupInputDefinition.new(**(attributes.merge(name: name)))
  )
end

#select(name, attributes = {}) ⇒ Object

Declares a select for this form, to be modeled via an HTML <SELECT> tag. Note that this will not define the values that appear in the select. That is done when the select is rendered, which you might do with a Components::Inputs::Select

Parameters:

  • name (String) —

    The name of the input (used in the name attribute)

  • attributes (Hash) (defaults to: {}) —

    Attributes to be used on the tag that represent its contraints. See SelectInputDefinition
