    @Expose
    private String lastname;

    @Expose @Ignore
    private List<Object> properties = new ArrayList<>();
    @SerializedName("rights")
    @Expose @Ignore
    private String rights;

    @Expose
    private String photo;

    private List<PointsOnMap> favorites = new ArrayList<>();
    @SerializedName("token")
    @Expose
    private String token;

    public User() {
    }

    public User(String name, String lastname, String email, String photo, String token) {
        this.name = name;
        this.lastname = lastname;
        this.email = email;
        this.photo = photo;
        this.token = token;
    }
    //getters and setters

推荐答案

问题是使用Sugar时您的类中不能有名为id的变量，因为默认情况下它使用自己的内部ID.尝试重命名为userId或类似名称.

Problem is you can't have a variable named id in your class when using Sugar since by default it uses its own internal ids. Try renaming to userId or something like that.
