How do I get at posted form data?

Tags: form controller post 0.30.0

I have a form that posts some values to a controller action.

How do get at the form values in my controller code?

For eaxmple, if my form has this field

<input type='text' name='foo' />

and I post to /controller/action

what is the code in the ‘action’ method to retreive that value of foo?

(2 attempts)

manveru answered:

def action
  if request.post? # check if you just got a POST
    request['foo'] # now you've got it :)
    request.params # list of all you've got
  end
end

Some discoveries:

  • The input fields must have a name attribute, not just an id.

  • Form POST data are available inside controller methods using request.params
