javascript - Breeze newValue.getProperty 不是函数

Question

我已经更新到新版本的 breeze 和 ef 6。在我这样做之后，我得到了错误

newValue.getProperty is not a function

每当我尝试执行扩展查询时。 (对于“正常”查询一切都很好)

这是我的 Mucsle 模型:

    public int MuscleId { get; set; }
    public string Name { get; set; }

    public int MuscleGroupId { get; set; }
    public  MuscleGroup MuscleGroup { get; set; }

对于肌肉群:

    public int MuscleGroupId { get; set; }
    public string Name { get; set; }

    public  ICollection<Muscle> Muscles { get; set; }

这是我的 DtabaseContext 配置:

public WebDatabaseContext()
            : base("DefaultConnection")
        {
            Configuration.LazyLoadingEnabled = false;
            Configuration.ProxyCreationEnabled = false;
        }

我尝试像这样获取数据:

数据服务中的函数:

getAllIncluding: function(controllerAction, including) {
            var query = breeze.EntityQuery.from(controllerAction).expand(including);
            return manager.executeQuery(query).then(querySucceeded).fail(getFailed);

            function querySucceeded(data) {
                items = data.results;
                return data.results;
            }
        }

函数调用:

$scope.getAllMuscles = function() {
        adminCrudService.getAllIncluding("Muscles", "MuscleGroup")
            .then(querySucceeded)
            .fail(queryFailed);

    };

对于较旧版本的 breeze 和 EF5，这是有效的，所以我想知道我做错了什么？

编辑

我相信，当我输入 url 时，我已经找到了导致问题的原因:

breeze/Service/Muscles?$expand=MuscleGroup

使用“旧”(旧版本的 breeze 和 EF 5)设置，输出是这样的:

[{"$id":"1","$type":"Test.Domain.Model.MuscleGroupAggregate.Muscle, Test.Domain.Model","MuscleId":1,"Name":"Biceps","NameInLatin":"","ImageUrl":null,"MuscleGroupId":1,"MuscleGroup":null},

{"$id":"2","$type":"Test.Domain.Model.MuscleGroupAggregate.Muscle, Test.Domain.Model","MuscleId":3,"Name":"Triceps","NameInLatin":"","ImageUrl":null,"MuscleGroupId":1,"MuscleGroup":null},

使用 EF 6 和最新版本的 breeze:

    [{"$id":"1","$type":"System.Collections.Generic.Dictionary`2[[System.String, mscorlib],[System.Object, mscorlib]], mscorlib","MuscleGroup":

{"$id":"2","$type":"System.Collections.Generic.Dictionary`2[[System.String, mscorlib],[System.Object, mscorlib]], mscorlib","MuscleGroupId":1,"Name":"TestMuscleG1","Description":"","ImageUrl":null},"MuscleId":1,"Name":"Test2","NameInLatin":"","ImageUrl":null,"MuscleGroupId":1},

{"$id":"3","$type":"System.Collections.Generic.Dictionary`2[[System.String, mscorlib],[System.Object, mscorlib]], mscorlib","MuscleGroup":

{"$id":"4","$type":"System.Collections.Generic.Dictionary`2[[System.String, mscorlib],[System.Object, mscorlib]], mscorlib","MuscleGroupId":1,"Name":"TestMuscleG1","Description":"","ImageUrl":null},"MuscleId":2,"Name":"32r23r","NameInLatin":"","ImageUrl":null,"MuscleGroupId":1}]

所以区别在于 $type 和"new"输出，甚至很难，在数据库中我只有两个条目，我有 4 个项目。

解决了!

所以问题出在这里:

[HttpGet]
        [Queryable(AllowedQueryOptions = AllowedQueryOptions.Supported | AllowedQueryOptions.Expand)]
        public IQueryable<Muscle> Muscles()
        {
            return _contextProvider.Context.Muscles;
        }

当我删除这一行时:

  [Queryable(AllowedQueryOptions = AllowedQueryOptions.Supported | AllowedQueryOptions.Expand)]

它就像一个魅力，

杰感谢所有的帮助:)
