运行下面的代码时我得到这个断言:
Emptying a view in the inBuffer state is not allowed and should not happen under normal circumstances. Most likely there is a bug in your application. This may be due to excessive property change notifications.

为什么会发生这种情况?
最佳答案
我在尝试从灯具加载下拉值列表时遇到了同样的错误。解决这个问题的方法是重写夹具适配器上的queryFixtures:
App.FixtureAdapter = DS.FixtureAdapter.extend
latency: 200
queryFixtures: (records, query, type) ->
records.filter (record) ->
for key of query
continue unless query.hasOwnProperty(key)
value = query[key]
return false if record[key] isnt value
true
如果我没有先设置延迟,我可能不会弄清楚这一点。然后错误更具描述性。
关于ember.js - ember 未捕获错误 : assertion failed: Emptying a view in the inBuffer state,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/14379979/
