rescue from ActiveRecord::RecordNotFound in Rails

Question

A user can only edit its own post, so I use the following to check if a user can enter the edit form:

  def edit
    @post = Load.find(:first, :conditions => { :user_id => session[:user_id], :id => params[:id]})
  rescue ActiveRecord::RecordNotFound
    flash[:notice] = "Wrong post it"
    redirect_to :action => 'index'
  end

But it is not working, any ideas what I am doing wrong?

Answer 1

If you want to use the rescue statement you need to use find() in a way it raises exceptions, that is, passing the id you want to find.

def edit
  @post = Load.scoped_by_user_id(session[:user_id]).find(params[:id])
rescue ActiveRecord::RecordNotFound
  flash[:notice] = "Wrong post it"
  redirect_to :action => 'index'
end
