I'm just learning MVC so you could find my question rather strange...

My Controller have access to different shared objects through Container object passed to Controller's constructor. To access shared objects I should do $this->container->db to access Database adapter or $this->container->memcache to access Memcached adapter. I want to know should I put View object into Container with shared objects or no?

From one side it is really comfortable to take view from this container, but this way I couldn't create multiple Views instances (for example, every time I'm calling Controller's method from View I should have one more View instance). What is the solution? How should I pass View 开发者_运维技巧object into Controller and/or how should I create new View instances from Controller?

Thank you!


If you want that DI experience, do it on views as well, but I don't know if it really helps you anyway. Never call controller methods from views. Instead write some partial view methods and call them from views, which define the page layout (something similar to what Rails does). IMHO if you want to get on MVC gradually, start from core principles and iteratively get to details, but don't learn architectural/design pattern as MVC by parts - architecture, design, the whole matters:)


Hmm, maybe try implementing caching for static parts. IMHO try inserting cacher object (through DI) to controller, and let that object decide if you want to send cached partial view or instantiate a new one. If you want to cache data from db, use the same pattern from controller towards models, so whenever in a controller you need models, ask db cacher object (same DI principle). Is it clear enough?
