我正在与 SilverStripe 合作，并且正在制作新闻页面。我使用 DataObjectAsPage 模块（http://www.ssbits.com/tutorials/2012/dataobject-as-pages-the-module/），当我使用管理员发布新闻站点时，我得到了它的工作。现在我想使用 DataObjectManager 模块而不是管理模块来管理我的新闻项目。但这就是问题所在。在草稿模式下一切正常，我可以制作一个新的新闻站点，它会显示在草稿中。但是当我想发布一个新站点时，它不会以实时或发布模式出现。
我正在使用以下表：
-Dataobjectaspage 表、
-Dataobjectaspage_live 表、
-NewsArticle 表、
-NewsArticle_Live 表
文章已在 Dataobjectaspage 表和 NewsArticle 表中发布时插入...但不是在 _Live 表中...
似乎在“发布”时未使用 doPublish() 函数。所以我正在尝试使用以下内容：
function onAfterWrite() {
parent::onAfterWrite();
DataObjectAsPage::doPublish();
}
但是当我使用它时，它会出现错误： 这是这张图片
它似乎处于一个循环中......我有 NewsArticle.php 文件，我在其中使用了这个函数：
function onAfterWrite() {
parent::onAfterWrite();
DataObjectAsPage::doPublish();
}
此函数调用 DataObjectAsPage.php 文件并使用以下代码：
function doPublish() {
if (!$this->canPublish()) return false;
$original = Versioned::get_one_by_stage("DataObjectAsPage", "Live", "\"DataObjectAsPage\".\"ID\" = $this->ID");
if(!$original) $original = new DataObjectAsPage();
// Handle activities undertaken by decorators
$this->invokeWithExtensions('onBeforePublish', $original);
$this->Status = "Published";
//$this->PublishedByID = Member::currentUser()->ID;
$this->write();
$this->publish("Stage", "Live");
// Handle activities undertaken by decorators
$this->invokeWithExtensions('onAfterPublish', $original);
return true;
}
然后它转到 DataObject.php 文件并使用 write 函数（）：
public function write($showDebug = false, $forceInsert = false, $forceWrite = false, $writeComponents = false) {
$firstWrite = false;
$this->brokenOnWrite = true;
$isNewRecord = false;
if(self::get_validation_enabled()) {
$valid = $this->validate();
if(!$valid->valid()) {
// Used by DODs to clean up after themselves, eg, Versioned
$this->extend('onAfterSkippedWrite');
throw new ValidationException($valid, "Validation error writing a $this->class object: " . $valid->message() . ". Object not written.", E_USER_WARNING);
return false;
}
}
$this->onBeforeWrite();
if($this->brokenOnWrite) {
user_error("$this->class has a broken onBeforeWrite() function. Make sure that you call parent::onBeforeWrite().", E_USER_ERROR);
}
// New record = everything has changed
if(($this->ID && is_numeric($this->ID)) && !$forceInsert) {
$dbCommand = 'update';
// Update the changed array with references to changed obj-fields
foreach($this->record as $k => $v) {
if(is_object($v) && method_exists($v, 'isChanged') && $v->isChanged()) {
$this->changed[$k] = true;
}
}
} else{
$dbCommand = 'insert';
$this->changed = array();
foreach($this->record as $k => $v) {
$this->changed[$k] = 2;
}
$firstWrite = true;
}
// No changes made
if($this->changed) {
foreach($this->getClassAncestry() as $ancestor) {
if(self::has_own_table($ancestor))
$ancestry[] = $ancestor;
}
// Look for some changes to make
if(!$forceInsert) unset($this->changed['ID']);
$hasChanges = false;
foreach($this->changed as $fieldName => $changed) {
if($changed) {
$hasChanges = true;
break;
}
}
if($hasChanges || $forceWrite || !$this->record['ID']) {
// New records have their insert into the base data table done first, so that they can pass the
// generated primary key on to the rest of the manipulation
$baseTable = $ancestry[0];
if((!isset($this->record['ID']) || !$this->record['ID']) && isset($ancestry[0])) {
DB::query("INSERT INTO \"{$baseTable}\" (\"Created\") VALUES (" . DB::getConn()->now() . ")");
$this->record['ID'] = DB::getGeneratedID($baseTable);
$this->changed['ID'] = 2;
$isNewRecord = true;
}
// Divvy up field saving into a number of database manipulations
$manipulation = array();
if(isset($ancestry) && is_array($ancestry)) {
foreach($ancestry as $idx => $class) {
$classSingleton = singleton($class);
foreach($this->record as $fieldName => $fieldValue) {
if(isset($this->changed[$fieldName]) && $this->changed[$fieldName] && $fieldType = $classSingleton->hasOwnTableDatabaseField($fieldName)) {
$fieldObj = $this->dbObject($fieldName);
if(!isset($manipulation[$class])) $manipulation[$class] = array();
// if database column doesn't correlate to a DBField instance...
if(!$fieldObj) {
$fieldObj = DBField::create('Varchar', $this->record[$fieldName], $fieldName);
}
// Both CompositeDBFields and regular fields need to be repopulated
$fieldObj->setValue($this->record[$fieldName], $this->record);
if($class != $baseTable || $fieldName!='ID')
$fieldObj->writeToManipulation($manipulation[$class]);
}
}
// Add the class name to the base object
if($idx == 0) {
$manipulation[$class]['fields']["LastEdited"] = "'".SS_Datetime::now()->Rfc2822()."'";
if($dbCommand == 'insert') {
$manipulation[$class]['fields']["Created"] = "'".SS_Datetime::now()->Rfc2822()."'";
//echo "<li>$this->class - " .get_class($this);
$manipulation[$class]['fields']["ClassName"] = "'$this->class'";
}
}
// In cases where there are no fields, this 'stub' will get picked up on
if(self::has_own_table($class)) {
$manipulation[$class]['command'] = $dbCommand;
$manipulation[$class]['id'] = $this->record['ID'];
} else {
unset($manipulation[$class]);
}
}
}
$this->extend('augmentWrite', $manipulation);
// New records have their insert into the base data table done first, so that they can pass the
// generated ID on to the rest of the manipulation
if(isset($isNewRecord) && $isNewRecord && isset($manipulation[$baseTable])) {
$manipulation[$baseTable]['command'] = 'update';
}
DB::manipulate($manipulation);
if(isset($isNewRecord) && $isNewRecord) {
DataObjectLog::addedObject($this);
} else {
DataObjectLog::changedObject($this);
}
$this->onAfterWrite();
$this->changed = null;
} elseif ( $showDebug ) {
echo "<b>Debug:</b> no changes for DataObject<br />";
// Used by DODs to clean up after themselves, eg, Versioned
$this->extend('onAfterSkippedWrite');
}
// Clears the cache for this object so get_one returns the correct object.
$this->flushCache();
if(!isset($this->record['Created'])) {
$this->record['Created'] = SS_Datetime::now()->Rfc2822();
}
$this->record['LastEdited'] = SS_Datetime::now()->Rfc2822();
} else {
// Used by DODs to clean up after themselves, eg, Versioned
$this->extend('onAfterSkippedWrite');
}
// Write ComponentSets as necessary
if($writeComponents) {
$this->writeComponents(true);
}
return $this->record['ID'];
}
看看 $this->onAfterWrite();
它可能会转到我自己在 NewsArticle.php 上的函数，然后开始循环！不过我不确定，所以我需要一些帮助！！
有谁知道如何使用 doPublish() 函数？
