MongoDB，在集合之间使用Mongodb ObjectID(MongoDB, Using Mongodb ObjectID between collections)

 使用PHP和MongoDB，我有一个名为users的集合，另一个在同一个DB中称为表单。  
 我使用Mongodb ObjectID作为表单集合中文档的用户标识符，将用户ObjectId保存为每个表单文档上的uid。  
 我将在表单集合中创建一个uid字段的索引，但我的问题是我应该如何保存用户Objectid？  
 截至目前，我将其保存为普通字符串，如（简化）  
$collection->insert( array('formName'=>'The name','uid'=>'CURRENT_USERS_ObjectId_AS_string') );
 
 在这种情况下，这似乎是逻辑或最佳实践，为uid创建Mongodb ObjectID  
$collection->insert( array('formName'=>'The name','uid'=> new MongoId('CURRENT_USERS_ObjectId_AS_string')) );

Using PHP and MongoDB, i have a collection called users and another one called forms in the same DB. 
I am using the Mongodb ObjectID as user identifier for the documents in the forms collection, saving the users ObjectId as uid on each forms document. 
I am going to create an index of the uid field in the forms collection, but my question is how i should save the users Objectid? 
As of now I am saving it as a normal string like (simplified) 
$collection->insert( array('formName'=>'The name','uid'=>'CURRENT_USERS_ObjectId_AS_string') );
 
Does this seem logic or is best practice in this case to create a Mongodb ObjectID for uid like 
$collection->insert( array('formName'=>'The name','uid'=> new MongoId('CURRENT_USERS_ObjectId_AS_string')) );

 的标记  
date-disabled="disabled(date, mode)"
 
 意味着在你的作用域中你需要有一个名为disabed的函数，它接受两个参数， date和mode ，你将用它来确定是否应该禁用该日期。  
 这是一个更清晰的例子。 制作标记  
date-disabled="shouldDateBeDisabled(date, mode)"
 
 然后在你的Controller中你需要将一个名为shouldDateBeDisabled的函数shouldDateBeDisabled到你将放置逻辑的$scope 。  
var datesAreEqual = function(date1,date2) {...};
var dateIsInArray = function(date,arrayOfDates) {...};
var someSingleDateToDisable = ...;
var arrayOfDatesToDisable = [...];
$scope.shouldDateBeDisabled = function(date, mode) {
  // your own logic to determine if a date should be disabled
  if (datesAreEqual(date,someSingleDateToDisable) {
    return true;
  }

  if (dateIsInArray(date,arrayOfDatesToDisable) {
    return true;
  }

  return false;
};

The markup of 
date-disabled="disabled(date, mode)"
 
means that in your scope you would need to have a function named disabed that accepts two arguments, date and mode, which you would use to determine if that date should be disabled. 
Here is a clearer example for you. Make the markup be 
date-disabled="shouldDateBeDisabled(date, mode)"
 
Then in your Controller you would need to attach a function named shouldDateBeDisabled to the $scope where you would put your logic. 
var datesAreEqual = function(date1,date2) {...};
var dateIsInArray = function(date,arrayOfDates) {...};
var someSingleDateToDisable = ...;
var arrayOfDatesToDisable = [...];
$scope.shouldDateBeDisabled = function(date, mode) {
  // your own logic to determine if a date should be disabled
  if (datesAreEqual(date,someSingleDateToDisable) {
    return true;
  }

  if (dateIsInArray(date,arrayOfDatesToDisable) {
    return true;
  }

  return false;
};
