Phalcon中子控制器结构的路由问题

Question

I've implemented a router , securityplugin (for ACL) and notfoundplugin .

I want my site to be set up with a subcontroller structure: Link

The website is set up in the following main parts:

• Index
• Admin
  • Tickets
• Account

The issues I have:

When calling: domain/admin/actionofadmin

Returns custom 404: "Page doesn't exist" instead of the normal action result

When calling: domain/admin/actionofadmin. (<-- mind the dot at the end)

Returns index action of index controller instead of the normal action result

Why does the router return theses results? How can they be fixed?

Extra questions:

• How does Phalcon know where to find a view and link it to the correct controller? Example: A dashboardController resides in a folder "admin" inside the folder "controllers".

• How does Phalcon know that in the SecurityPlugin ACL it needs to search for the correct controller while it doesn't get a namespace? Example: When I want to allow controller Tickets of namespace app\\controllers\\admin to be only viewed by admin users.

Extra information:

• Phalcon 3.0.3
• PHP 5.6

Let me know if you need any more information / files or if I should post it somewhere else for ease of reading.

When calling: domain/admin/actionofadmin (as i understand domain is for example www.google.pl ) phalcon is expecting ActionofadminController according to your routes. Are you sure there is such controller? Don't sure why with with dot it's hitting index controller and index action though.

How does Phalcon know where to find a view and link it to the correct controller? Example: A dashboardController resides in a folder "admin" inside the folder "controllers".

It's getting this info from dispatcher. Mvc application if you don't render view your self is implicit automatically rendering. Check this source: https://github.com/phalcon/cphalcon/blob/master/phalcon/mvc/application.zep#L348 And other view classes.

About Acl Plugin - it doesn't check for namespace at all. So if you have two controllers with same name but other namespace this wil cause obviously a problem. You just need to change security plugin to your needs.
