Send form validation errors through redirect?

Hi,

I'm new at this, how do I send the errors that one would get from a standard ruby scaffold generator on a form that is attempted to POST incorrectly? With all the beautiful formatting etc...

Right now I have this:

  # POST /environments   # POST /environments.xml   def create     @project = Project.find(params[:project_id])     # @environment = Environment.new(params[:environment])     @environment = @project.environments.create(params[:environment])     if @environment.save       redirect_to project_path(@project), :notice => 'Saved'     else       redirect_to project_path(@project), :notice => 'Error'     end

And it works, but I only get what I define: "Error", whereas I would like to get the explicit errors that the validators are catching... something like: (does not work)

  # POST /environments   # POST /environments.xml   def create     @project = Project.find(params[:project_id])     # @environment = Environment.new(params[:environment])     @environment = @project.environments.create(params[:environment])     if @environment.save       redirect_to project_path(@project), :notice => 'Saved'     else       rescue ActiveRecord::RecordInvalid => invalid          @error = invalid.record.errors         end       redirect_to project_path(@project), :notice => @error     end

Any suggestions?
