Overview
This class is intended to be a proxy for a FormBuilder object, and accumulate multiple form elements rendered inside a block. Its main reason for existence is to enable the following syntax when rendering revealing panels:
f.radio_button_fieldset :asked_for_help do |fieldset|
fieldset.radio_input(GenericYesNo::YES) do |radio|
# Here, `radio` is a `BlockBuffer` instance, delegating all methods to
# a `FormBuilder` instance, but doing the accumulation/concatenation.
radio.text_field(:help_party)
radio.text_field(:another_field)
[...]
end
fieldset.radio_input(GenericYesNo::NO)
end
