The problem is that you've got form_for [:admin, :user] instead of
form_for [:admin, @user] and then you're expecting (somehow)
f.radio_button to know which user to use to retrieve the seed value.
Rails is using the last element of that array and calling
the .approval method on it (hence the error about the user:Symbol
(ie. :user ) not having that method defined.
You're more likely to want to put the form within the @users iteration
block, so that you have a separate form for each user. You can then do:
<% for user in @users %>
<% form_for [:admin, user] ...etc. do %>
<%= f.radio_button :approval ...etc. %>
If not, if you want it all in one form, then you won't be able to use
the form_for block helpers, rather you'll need to use radio_button_tag
and setup the values and names manually.
