Hi,
This is the controller: @thermo_detector = ThermoDetectorOrderLetter.find(@params[:id])
@thermo_detector[:number_of_element] = '1 Element' # this is ok @number_of_element_helper['1element'] = 'bla' # not ok
This is the view: <%= radio_button(:thermo_detector, :number_of_element, '1 Element') %>1 Element <%= text_field('number_of_element_helper', '1element') %><br /> another radio button
This line is source of my problem: @number_of_element_helper['1element'] = 'bla'
It made me got this error: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occured while evaluating nil.=
If I comment that, the code works: radio_button with value '1 Element' is checked, but the text field is empty. How do I send value from controller to this text field text_field('number_of_element_helper', '1element') where number_of_element_helper is not variable from model???
Thank you.
