Shortest Yet       f hidden field  title   value   gt   some value    Shorter  DRYer and perhaps more obvious   Of course with ruby 1 9 and the new hash format we can go 3 characters shorter with      f hidden field  title  value   some value

f input field  title  as   hidden  value   some value    Is also an option  Note  however  that it skips any wrapper defined for your form builder

try this    f input  title   as   gt   hidden   input html   gt     value   gt   some value

Correct way  if you are not trying to reset the value of the hidden field input  is       f hidden field  method   value   gt  value of the hidden field as it comes through in your form   Where     method    is the method that when called on the object results in the value you want   So following the example above     simple form for  movie do  f      f hidden  title   some value      f button  submit   The code used in the example will reset the value   title  of  movie being passed by the form  If you need to access the value   title  of a movie  instead of resetting it  do this      simple form for  movie do  f      f hidden  title   value   gt  params  movie   title      f button  submit   Again only use my answer is you do not want to reset the value submitted by the user    I hope this makes sense
