通过后端在app.yml中编辑值 [英] edit values in app.yml by backend
问题描述
$ this-> pager = new sfDoctrinePager(
'JobeetJob',
sfConfig :: get('app_max_jobs_on_category')
);
$ this-> pager-> setQuery($ this-> category-> getActiveJobsQuery());
$ this-> pager-> setPage($ request-> getParameter('page',1));
$ this-> pager-> init();
}
sfConfig :: get('app_max_jobs_on_category')
#apps / frontend / config / app.yml
all:
active_days:30
max_jobs_on_homepage:10
max_jobs_on_category:20
我让该管理员可以在后端编辑这个值(max_jobs_on_category)?
每个用户是否可以只为自己编辑?
我认为你更好地创建一个数据库这些设置的模型。然后,您可以在过滤器中查询数据库,例如(参见 http://www.symfony-project.org/gentle-introduction/1_4/en/06-Inside-the-Controller-Layer#chapter_06_sub_the_filter_chain )。
例如:
AppSetting:
columns:
id:
type:integer(4)
primary:true
name:
type:string(100)
notnull:true
value:
type :string(100)
示例过滤器代码:
$ settings = Doctrine_Core :: getTable('AppSetting') - > fetchAll();
foreach($ settings as $ setting){
sfConfig :: set($ setting-> getName(),$ setting-> getValue());
}
当然这是额外的开销,每次请求加载所有这些设置,你可以只需在需要时查询它们:
Doctrine_Core :: getTable('AppSetting') - > findOneByName('some_setting') - >的getValue();
或者你可以更进一步,为他们创建一些序列化缓存。但是最终,如果您需要从Web界面进行编辑,我会去找一个数据库解决方案。
public function executeShow(sfWebRequest $request)
{
$this->category = $this->getRoute()->getObject();
$this->pager = new sfDoctrinePager(
'JobeetJob',
sfConfig::get('app_max_jobs_on_category')
);
$this->pager->setQuery($this->category->getActiveJobsQuery());
$this->pager->setPage($request->getParameter('page', 1));
$this->pager->init();
}
sfConfig::get('app_max_jobs_on_category')
# apps/frontend/config/app.yml
all:
active_days: 30
max_jobs_on_homepage: 10
max_jobs_on_category: 20
how can i make that admin can edit this values (max_jobs_on_category) in backend? And is possible that each user can this edit only for himself?
I think you are better creating a database model for those settings. You could then query the database in a filter for example (see http://www.symfony-project.org/gentle-introduction/1_4/en/06-Inside-the-Controller-Layer#chapter_06_sub_the_filter_chain).
For example:
AppSetting:
columns:
id:
type: integer(4)
primary: true
name:
type: string(100)
notnull: true
value:
type: string(100)
Example filter code:
$settings = Doctrine_Core::getTable('AppSetting')->fetchAll();
foreach ($settings as $setting) {
sfConfig::set($setting->getName(), $setting->getValue());
}
Ofcourse this is some extra overhead to load all these settings every request, you could just query them as you need them:
Doctrine_Core::getTable('AppSetting')->findOneByName('some_setting')->getValue();
Or you could go even further and create some serialized cache for them. But in the end, I'd go for a database solution if you need to edit them from a web interface.
