admin - Sonata/symfony - parent/child structure setup -

I'm asking for a while. Can not believe there is not a single god who does not know the answer and I am a little disappointed.

In Sonata, I can not work with URL structure / pattern / parent / id / children / list. Lot, rather went through bad 4.6.

Can anyone explain step-by-step to establish such a structure?

I will use the example given in my explanation, a basic post / comment relationship.

The parent / child link (one team / multiple lessons link) between your organizations (parent) and comment (child).

You must add to the service announcement that adds the addadd group that targets the child's admin service:

services.yml

  Sonata.news.admin.comment: Class: sonata \ newsbundle \ admin \ adminAdmin logic: [~, sonata \ newsbundle \ model \ remark, sonata news bundle: comment admin] Tags: - {name: sonata.admin, manager_type: orm, Group: "content"} sonata.news.admin.post: class: Sonata \ NewsBundle \ Admin \ PostAdmin logic: [~, sonata \ newsbundle \ model \ post, sonata news bundle: post Min] Tags: - {name: sonata.admin, manager_type: orm, group: "content"} call: - [addChild, ['sonata.news.admin.comment']]  

Comment in your Admin Class, you need to add propertiesAccident Mapping to parents to filter this child.

Comment Administrator

  Expands class CommentAdmin Administrator {Protected $ parentAssociationMapping = 'post'; ...}  

Then you will have a new route available: / parent / ID / child / list, you can use the console to find your new root identifier (Php app) / console router: debug). If you want an easy way to use it in the admin, then I suggest adding a button directly to the parent admin list to access your child's comments:

Create a template that Add a button to access the child Comment:

post_comments.html.twig

  & lt; One class = "btn btn-sm btn-default" href = "{{path ('OUR_NEW_CHILD_ROUTE_ID', {'id': object.id})}}" & gt; Comments & lt; / A & gt;  

Then add button action in the parent admin in this case. PostAdmin:

PostAdmin

  Extension of class post admin administrator (protected work) structure ('show' => array), 'edit' = & gt; Array ()), 'annotations' = & gt; Array ('Template' = & gt; 'PATH_TWIG'))))}}  

Hope you set up the parent / child administrator
