Labels for radio buttons in rails form

Question

My question is similar to this one but for a Rails app   I have a form with some radio buttons  and would like to associate labels with them  The label form helper only takes a form field as a parameter  but in this case I have multiple radio buttons for a single form field  The only way I see to do it is to manually create a label  hard coding the ID that is auto generated for the radio button  Does anyone know of a better way to do it   For example    lt   form for  message  do  f    gt       lt    label  contactmethod   gt       lt    f radio button  contactmethod   email    checked   gt  true   gt  Email      lt    f radio button  contactmethod   sms    gt  SMS  lt   end   gt    This generates something like    lt label for  message contactmethod  gt Contactmethod lt  label gt   lt input checked  checked  id  message contactmethod email  name  message contactmethod   value  email  type  radio  gt  Email  lt input id  message contactmethod sms  name  message contactmethod   value  sms  type  radio  gt  SMS   What I want    lt input checked  checked  id  message contactmethod email  name  message contactmethod   value  email  type  radio  gt  lt label for  message contactmethod email  gt Email lt  label gt   lt input id  message contactmethod sms  name  message contactmethod   value  sms  type  radio  gt   lt label for  message contactmethod sms  gt SMS lt  label gt

If you want the object name prefixed to any ID you should call form helpers on the form object   - form for  message  do  f      f label  email   This also makes sure any submitted data is stored in memory should there be any validation errors etc   If you can t call the form helper method on the form object  for example if you re using a tag helper  radio button tag etc   you can interpolate the name using     radio button tag    f object name  email     message email   In this case you d need to specify the value manually to preserve any submissions

Passing the  value option to f label will ensure the label tag s for attribute is the same as the id of the corresponding radio button    lt   form for  message  do  f    gt     lt    f radio button  contactmethod   email    gt      lt    f label  contactmethod   Email    value   gt   email    gt     lt    f radio button  contactmethod   sms    gt     lt    f label  contactmethod   SMS    value   gt   sms    gt   lt   end   gt    See ActionView  Helpers  FormHelper label     the  value option  which is designed to target labels for radio button tags
