make flash() available on same request?

[jeroenbourgois]

I am having trouble using the flash().

I have a form, and in the POST route dispatch function, I validate the form. If it is invalid, I call flash() and render my view, but first the flash_now() is empty (as stated in the readme, I know).

But isn't it usefull to have it right away? Because now I need to set('error', 'some_message') instead,

flash() is made to pass messages between pages. It works like the flash in RoR

The flash is a special part of the session which is cleared with each request. This means that values stored there will only be available in the next request, which is useful for storing error messages etc.

If you just need to display something on your view, using set is the right thing to do.
