如何从服务器重新加载数据?

How can I reload the data from the server?

推荐答案

我刚推送 记录.reload() 到 Ember 数据.这将要求适配器从服务器重新加载数据并使用新数据更新记录.

I just pushed record.reload() to Ember Data. This will ask the adapter to reload the data from the server and update the record with the new data.

• 您只能在已完成加载且尚未修改的记录上调用 reload().否则，返回的数据将与修改后的数据发生冲突.将来，我们将添加对合并挂钩的支持以解决此类冲突，这将允许 reload() 处于更多记录状态.
• 如果您在适配器返回新数据之前调用 reload() 并更改或保存记录，您将因同样的原因收到错误消息.该错误目前看起来类似于 Attempted to handle event 'reloadRecord' on 而处于 rootState.loaded.updated.uncommitted 状态..基本上，这意味着您的记录处于已更新但未提交"状态，并且不允许在加载和未修改"状态之外调用 reload().

• You can only call reload() on a record if it has completed loading and has not yet been modified. Otherwise, the returned data will conflict with the modified data. In the future, we will add support for a merge hook to address these sorts of conflicts, which will allow reload() in more record states.
• If you call reload() and change or save the record before the adapter returns the new data, you will get an error for the same reason. The error currently looks something like Attempted to handle event 'reloadRecord' on <Person:ember263:1> while in state rootState.loaded.updated.uncommitted.. Basically, this means that your record was in the "updated but uncommitted" state, and you aren't allowed to call reload() outside of the "loading and unmodified" state.
