Access protected flash in block of before_filter?

Rails
1

Hi all

I’d like to put a block after a before_filter instead of calling a
separate method because I think it’s looking cooler. :wink:

before_filter :only => [:new, :create] do |controller|
flash[:notice] = “That is not allowed!.”
redirect_to :referer
end

Sadly this doesn’t work:

ndefined local variable or method `flash’ for
SchmuckSeitenController:Class

I tried it with controller.flash, but then Rails tells me it is
protected.
Is there a way to access flash? :slight_smile:

Thanks
Josh

You can wrap your filter body in a controller.instance_eval block.

But this is really a job for verify:

We develop, watch us RoR, in numbers too big to ignore.

Thanks, mate. I tried it the following way, but it doesn’t work:

verify :only => [:new, :create],
:add_flash => {:notice => ‘Creation is deactivated.’},
:redirect_to => :back

I want to prevent the user from creating a new object, but maybe later I
will allow it to the user. So I just want to make sure he can’t access
the new and create methods.
