On a search page with url than act like filter some argument can be set more than one time.
So in a twig template I'm trying to build an url like that:
app?param1=2&toto[]=3&toto[]=10&toto[]=20
How do you manage to do that in twig?
I'm already merging the request query with entity attribute (in a loop)
path('search', app.request.query.all | merge({state: state.id}))
Don't do this in you're view, build it in your controller and pass it down to the view.
Views should be logic-less IMO.
