Support controller in subdirectory

[swordream]

In 1.1,it support controller like:

/modules/yyy/controllers/xxxx/DefaultController.php

the route is r=yyy/xxx/default/index

it seems 2.0 doesn't support this

[samdark]

What's the use case for it?

[swordream]

a self contained modules including frontend part and backend part
for example, an article module's structre may be:
modules/article/controllers/AccountController implments register,login,logout
modules/article/controllers/admin/AccountController implements create,delete, and it can be used by admin modules or backend applicaton

We dropped the support for using subdirectories in controllers folder, as it is not commonly used, and when it is needed, you can use sub-modules to achieve similar effect.

[swordream]

i think sub-modules and sub-directory is two different ways to classify controllers,and in most cases it's better than submodules , beacause it is more lightweight and simple.

[qiangxue]

Yes, they're different things. One of the main reasons we dropped sub-directory of controllers support is for simplicity. For example, given a route admin/post/create, can you tell the actual controller class file immediately?

Using subdirectory is a bit more lightweight, but not necessarily simpler, especially when you are also using modules.

[swordream]

Complexity left to framework itself, Simplicity left to the users.
I think the module developers will know very well where actual controller class ,and to end users ,it's not important that where is actual controller class file.
BTW:framwork should should provide a variety of choice,and how to use left to the developers

I think both solutions are great. Personally I use subfolder instead of sub-module when a sub-module only has one controller and when I need two o more controllers I create a sub-module.

If we could have both solutions would be amazing,

I stopped using subfolders for my controllers when I got fet up with having to create URL rules just to make e.g. /admin work (where admin is the subfolder name). I think it is way cleaner to use modules, and it's just one small module folder and class file away.

I would be very pleased if the docs reflected this lack of support,

https://www.yiiframework.com/doc/guide/2.0/en/structure-controllers#controller-ids

I have developed an application with lots of controllers under and admin subdir only to find that it is not supported and now I have to refactor everything to a module.
It would have save me a lot of time to read that there is limited support, and that, for example, urls like:

/admin/user/update/1

won't work and you have to use

/admin/user/update?id=1

Thanks!
