Question

我需要我的代码的帮助，该代码显示用户的帖子列表以及用户名。我想要的是，当我单击特定帖子的用户名时，它应该将我发送到该用户的个人资料。相反，它将发送到我自己的个人资料或当前用户的个人资料，而我希望它将我链接到我单击个人资料的用户名。（例如，当您单击Instagram上的用户名时，它会将您链接到用户的个人资料，以便您可以关注或取消关注并查看他们的信息）请我需要帮助。我在代码中做的不正确。我在轨道上5.2.3和红宝石2.3.3

我想问题是，在public static MyEvent getMostRecentLastEventOfSequence( SortedSet<MyEvent> events, List<String> sequence) { String first = sequence.get(0), second = sequence.get(1); UnaryOperator<MyEvent> previous; Stream<MyEvent> stream; if (events instanceof NavigableSet) { NavigableSet<MyEvent> navigableSet = (NavigableSet<MyEvent>) events; previous = navigableSet::lower; stream = navigableSet.descendingSet().stream(); } else { previous = event -> events.headSet(event).last(); stream = Stream.iterate(events.last(), previous).limit(events.size()); } return stream .filter(event -> event.getAbbreviation().equals(second)) .filter(event -> { MyEvent p = previous.apply(event); return p != null && p.getAbbreviation().equals(first); }) .findFirst().orElse(null); }的{{1}}方法上，您是从current_user而不是从用户那里获取帖子的，它应该是show

单击另一个用户的用户名链接到我的个人资料，而不是该用户的个人资料
