Question

我想访问我的技术人员的孙子＆＃39;实体

层次：

实体用户 - ＆gt; PersonalDetails

实体技术员 - ＆gt;用户

尝试时

/** AdminBundle/Admin/TechnicianAdmin.php */ 

$formMapper
    ->add('user.personalDetails','sonata_type_admin',[
         'delete'=>false
    ]);

我收到此错误

属性＆＃34; personalDetailsuser＆＃34;也不是其中一种方法＆＃34; getPersonalDetailsuser（）＆＃34;，＆＃34; personalDetailsuser（）＆＃34;，＆＃34; isPersonalDetailsuser（）＆＃34;，＆＃34; hasPersonalDetailsuser（）＆＃ 34;，＆＃34; __ get（）＆＃34;在课堂上存在并具有公共访问权限＆＃34; AppBundle \ Entity \ Technician＆＃34;。

然而尝试这个：

/** AdminBundle/Admin/UserAdmin.php */ 

$formMapper
    ->add('personalDetails','sonata_type_admin',[
         'delete'=>false
    ]);

Everythings按预期工作100％。我可以在我的UserAdmin类中将PersonalDetails嵌入sonata_type_admin，但不能在我的TechnicianAdmin类[包含User对象]中嵌入。如何在我的TechnicianAdmin课程中嵌入PersonalDetails？我希望我清楚，请让我知道任何困惑。

Answer 1

您可以尝试将getter和setter添加到实体/** AppBundle/Entity/Technician.php */ // getter getPersonalDetails () { return $this->getUser()->getPersonalDetails(); } // setter setPersonalDetails(PersonalDetails $personalDetails) { $this->getUser()->setPersonalDetails($personalDetails); }，例如

TechnicianAdmin

并在/** AdminBundle/Admin/TechnicianAdmin.php */ $formMapper ->add('personalDetails','sonata_type_admin',[ 'delete'=>false ]);：

中定义字段

    function traverse_directory(entry) {
        let reader = entry.createReader();
        // Resolved when the entire directory is traversed
        return new Promise((resolve_directory) => {
            var iteration_attempts = [];
            (function read_entries() {
                // According to the FileSystem API spec, readEntries() must be called until
                // it calls the callback with an empty array.  Seriously??
                reader.readEntries((entries) => {
                    if (!entries.length) {
                        // Done iterating this particular directory
                        resolve_directory(Promise.all(iteration_attempts));
                    } else {
                        // Add a list of promises for each directory entry.  If the entry is itself 
                        // a directory, then that promise won't resolve until it is fully traversed.
                        iteration_attempts.push(Promise.all(entries.map((entry) => {
                            if (entry.isFile) {
                                // DO SOMETHING WITH FILES
                                return entry;
                            } else {
                                // DO SOMETHING WITH DIRECTORIES
                                return traverse_directory(entry);
                            }
                        })));
                        // Try calling readEntries() again for the same dir, according to spec
                        read_entries();
                    }
                }, errorHandler );
            })();
        });
    }

    traverse_directory(my_directory_entry).then(()=> {
        // AT THIS POINT THE DIRECTORY SHOULD BE FULLY TRAVERSED.
    });
