我想创建这样一个团队名单。
TeamHolder - 所有球队。 有Teampages儿童
TeamPage - 团队的描述和形象。 而且还有一个HAS_ONE关系TeamMember（数据对象）
TeamMember - 拥有成员。 在这里你也应该可以定义哪些队玩家。 这里是我的代码这一点。 但是我不知道我可以做的has_many关系到我的团队网页，让您可以选择多个团队的一名球员。 有没有人一个解决方案？

如果你想1播放器（TeamMember）是在多个团队和团队有多个玩家，你需要一个many_many。 如果您在此处使用的has_many，那么球队将有一个PlayerID，这意味着只能在每队1名球员。
class TeamPage extends Page {
private static $many_many = array('TeamMembers' => 'TeamMember');
public function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root', Tab::create('MembersTab', 'Team Members'));
$fields->addFieldToTab('Root.MembersTab', GridField::create('TeamMembers', 'The Team Members', $this->TeamMembers(), GridFieldConfig_RelationEditor::create());
return $fields;
}
}
class TeamMember extends DataObject {
private static $belongs_many_many = array('Teams' => 'TeamPage');
public function getCMSFields() {
$fields = FieldList::create();
if (!$this->isInDB()) {
// if the TeamMember has not been saved yet, display a message that it needs to be saved before teams can be assigned
$fields->push(ReadOnlyField::create('Teams', '', 'Save to assign Teams'));
} else {
$config = GridFieldConfig_RelationEditor::create();
// if you don't want the "add a new team" button on this grid, you can remove that with the following line:
// $config->removeComponentsByType('GridFieldAddNewButton');
$fields->push(GridField::create('Teams', 'Team this Member is in', $this->Teams(), $config);
}
return $fields;
}
}
这里注意，我用GridFieldConfig_RelationEditor代替GridFieldConfig_RecordEditor增加了一个GridFieldAddExistingAutocompleter您gridfield，让你链接的对象。
