The solution here is to allow the ActiveAdmin controller to update the role ids related to the user.
ActiveAdmin.register User do
permit_params :email, :password, :password_confirmation, role_ids: []
Here's a form that shows a check box for each global role.
form do |f|
f.inputs "User Details" do
f.input :email
f.input :password
f.input :password_confirmation
f.input :roles, as: :check_boxes
end
f.actions
end
While we're at it, we might as well make it possible to update the user without entering their password:
# Allow form to be submitted without a password
controller do
def update
if params[:user][:password].blank?
params[:user].delete "password"
params[:user].delete "password_confirmation"
end
super
end
end
Put all of this in the app/admin/user.rb.
