Passing config paramater to all presenters

Etruska

Hi,
I would like to pass parameter(s) from configuration to <head> section in layout so it probably has to be passed to all front-end presenters. I guess I could make a service which only purpose would be to carry the parameter and inject the service to BasePresenter. However I don't find such service very useful and also I've read some bad things about using BasePresenter. What would you recommend? Thank you for your advice.

Base presenter is fine, and so is your solution, so I'd say go ahead…

Hi, you could make a component {control head}.

Ad BasePresenter: I prefer using traits which I pass to presenter. E.g. TWebloaderComponents is more clear than BasePresenter.

@**Tomáš Votruba**: I must admit traits are fairly new to me. It does look better then BasePresenter, I'll give it a try :).

Ad component: Component makes sense but I would still have to pass config parameters via service, right? Or am I missing something?

Tomáš Votruba

You can pass it directly to component.

services:
    -
        implement: IHeadComponent
        setup:
            - setParameters(@Nette\DI\Container::parameters)

It's called generated factories, see this article (in czech)

I didn't know about this feature, it's really neat :). Thank you.
