How to: implement sentry 2 permissions with Laravel 4?
提问by Ray
I'm trying to use cartalyst sentry 2 in my site being built with Laravel 4. Basically I don't understand how to implement permissions.
我正在尝试在使用 Laravel 4 构建的站点中使用 cartalyst sentry 2。基本上我不明白如何实现权限。
The examples I've seen for permissions for a group specify the following as an example:
我所看到的组权限示例将以下内容指定为示例：
{
"name" : "Administrator",
"permissions" :
{
"user.create" : 1,
"user.delete" : 1,
"user.view" : 1,
"user.update" : 1
}
}
SO this is setting permissions for the admin group. BUT where are these permissions set?
所以这是为管理员组设置权限。但是这些权限在哪里设置？
In the table 'groups' there is a field called permissions which is a text field - are they set there - if so how? Or are these set in a model or controller?
在“组”表中，有一个名为权限的字段，它是一个文本字段 - 它们是否设置在那里 - 如果是，如何设置？或者这些设置在模型或控制器中？
Can anyone point me to s step by step on how to use in a laravel 4 app? I've read the supporting docs which foes through the functions but I'm just not sure how to set the data to get the functions to work.
谁能告诉我如何在 laravel 4 应用程序中使用的步骤？我已经阅读了支持函数的支持文档，但我不确定如何设置数据以使函数正常工作。

Basically you have to..
基本上你必须..
Create your groups
创建您的群组
Sentry::getGroupProvider()->create([
'name' => 'Super Administrators',
'permissions' => [
'system' => 1,
],
]);
Sentry::getGroupProvider()->create([
'name' => 'Managers',
'permissions' => [
'system.products' => 1,
'system.store' => 1,
'system.profile' => 1,
],
]);
Set a group to a particular user, in this case it is setting Managers to the current logged user
将组设置为特定用户，在这种情况下，它将管理器设置为当前登录的用户
Sentry::getUser()->addGroup( Sentry::getGroupProvider()->findByName('Managers') );
Check if a user has a particular access
检查用户是否具有特定访问权限
if ( Sentry::getUser()->hasAnyAccess(['system','system.products']) )
{
// Will be able to do a thing
}
Check if a user is Super Administrator (only this group has the 'system' access)
检查用户是否是超级管理员（只有该组具有“系统”访问权限）
if ( Sentry::getUser()->hasAnyAccess(['system']) )
{
// Will be able to do a thing
}
Get all groups from a particular user
从特定用户获取所有组
try
{
// Find the user using the user id
$user = Sentry::getUserProvider()->findById(1);
// Get the user groups
$groups = $user->getGroups();
}
catch (Cartalyst\Sentry\Users\UserNotFoundException $e)
{
echo 'User was not found.';
}

In your groupstable you set the permissions using JSON.
在您的groups表中，您使用 JSON 设置权限。
I have the following columns:
我有以下几列：
id | name | permissions
id | name | permissions
And a row:
还有一行：
1 | admin | {"admin":1, "create_news": 1}
1 | admin | {"admin":1, "create_news": 1}
Assign a user to a group using the table users_groups
使用表将用户分配到组 users_groups
Now you can use the following example to check if a user have a given permission:
现在您可以使用以下示例来检查用户是否具有给定的权限：
$user = Sentry::getUser();
if ($user->hasAccess('create_news')) {
echo "You can create a news item";
}
else {
echo "You can't create a news item";
}
