silverstripe dopublish函数为ModelAdmin管理页面 [英] silverstripe dopublish function for ModelAdmin managed Pages

问题描述

在银幕后端我通过ModelAdmin管理某些PageTypes。到目前为止，工作正常，唯一的事情我不能弄清楚是如何使一个页面是发布保存时。

这是我的代码： p>

  class ProjectPage extends Page {
 public function onAfterWrite（）{
 $ this-> doPublish 
 parent :: onAfterWrite（）; 
} 
} 
  

现在我仍然可以看到ModelAdmin创建的Sitetree中的页面，我可以看到它们处于草稿模式。如果我使用上面的代码，我得到这个错误：
在
... / framework / model / DataList.php中超过30秒的最大执行时间

许多thx，
Florian

解决方案

得到超出最大执行时间的原因是因为 $ this-> doPublish（）; 调用 $ this-> write（）; $ c> $ this-> onAfterWrite（）; 。有你有无尽的循环。
这样做在 onAfterWrite（）或 write（）不工作

你应该只显示保存&发布按钮而不是保存按钮
但我想它的说起来容易做起来。
添加一个按钮实际上只是几行，但我们还需要一个提供按钮所说的功能。

这听起来像完美的呼吁创建一个新的模块，允许在模型管理中正确处理页面。我在SS2.4做了这个，我有一个很好的想法，如何做在SS3，但本周没有时间，在周末戳我在银河irc频道，也许我有时间在周末。 / p>

in the silverstripe backend I´m managing certain PageTypes via a ModelAdmin. That works fine so far, the only thing i can´t figure out is how to make a Page being "Published" when saving it.

Thats my code:

class ProjectPage extends Page { 
    public function onAfterWrite() {
        $this->doPublish();
        parent::onAfterWrite();
    }
}

At the moment I can still see the ModelAdmin-created Pages in the Sitetree and I can see they are in Draft Mode. If I use the code above I get this error: Maximum execution time of 30 seconds exceeded in .../framework/model/DataList.php

Many thx, Florian

解决方案

the reason why you get "Maximum execution time exceeded" is because $this->doPublish(); calls $this->write(); which then calls $this->onAfterWrite();. And there you have your endless loop. So doing this in onAfterWrite() or write() doesn't really work

you should just display the save & publish button instead of the save button But I guess its easier said than done. Well adding a button is actually just a few lines, but we also need a provide the functions that do what the button says it does.

This sounds like the perfect call for creating a new Module that allows proper handling of Pages in model admin. I have done this in SS2.4, and I have a pretty good idea of how to do it in SS3, but no time this week, poke me on the silverstripe irc channel on the weekend, maybe I have time on the weekend.
