从解决方案访问集合 [英] Access to a collection from resolve

问题描述

如何从流星帐户模块的用户集合中验证特定字段?

How can I verify a specific field from the users collection of the accounts module of meteor ?

假设下一个代码:

$stateProvider.state('myState', {
  resolve:{
    function($q) {
      if(Meteor.userId()){
        return $q.resolve();
      }

      else {
        retrun $q.reject();
      }
    }
  }
})

在内部可以使用Meteor.userId()函数从用户中检索_id，但是我不能以相同的方式使用Meteor.user()函数.如何从resolve

Inside the resolve is possible to use the Meteor.userId() function to retrieve the _id from the user, but I cant use the Meteor.user() function in the same way. How can I retrieve custom data from that collection from the resolve

推荐答案

这有些棘手，但是在您所在的州/省以下代码可以解决此问题:

This is a little tricky, but solvable with this code in your state:

resolve: {
    currentUser: ($q) => {
        var deferred = $q.defer();

        Meteor.autorun(function () {
            if (!Meteor.loggingIn()) {
                if (Meteor.user() == null) {
                    deferred.reject('AUTH_REQUIRED');
                } else {
                    deferred.resolve(Meteor.user());
                }
            }
        });

        return deferred.promise;
    }
}

这将确保在加载Meteor.user()记录之前，路由不会解析，并且如果未登录，则拒绝该路由.我花了一段时间才找到它，但现在是管理员:)

This will ensure that the route does not resolve until the Meteor.user() record is loaded, and if not logged in, rejects the route. It took me a while to find this one, but it's a keeper now :)
