Api-Platform - 超媒体模型 - 响应所有链接

I try to return an Hypermedia Object (with all _links) and i get only 'self' value.

Who can i set Update, Put, Delete links ?

I've set " formats: jsonhal: ['application/hal+json']" in my config. Set accessControl,... i think i've not understand somthing ^^'

{
  "_links": {
    "self": {
      "href": "/api/modules"
    },
    "item": [
      {
        "href": "/api/modules/1"
      },
      {
        "href": "/api/modules/2"
      }
    ]
  },
  "totalItems": 2,
  "itemsPerPage": 30,
  "_embedded": {
    "item": [
      {
        "_links": {
          "self": {
            "href": "/api/modules/1"
          }
        },
        "id": 1,
        "title": "Module Premier",
        "description": "Description Premier Admin"
      },
      {
        "_links": {
          "self": {
            "href": "/api/modules/2"
          }
        },
        "id": 2,
        "title": "Deuxieme Modules",
        "description": "Description du deuxieme module"
      }
