Ack, sorry. Didn’t mean to hit submit.

This is the code for delete_user:


def delete_user
    if request.post?
      user = User.find(params[:id])
      begin
        user.destroy
        flash[:notice] = "User #{user.name} deleted." 
      rescue Exception => e
        flash[:notice] = e.message
      end
    end
    redirect_to(:action => :list_users)
  end

The problem line, apparently, is 46: user = User.find(params[:id])

But, I don’t know why it’s wrong. Any thoughts?

I’ve copied the delete_user action directly from the book. It’s exactly the same. However, instead of deleting a user, I get this error:

ActiveRecord::RecordNotFound in LoginController#delete_user

Couldn't find User with ID=user
