ExtJS 4：没有模型的网格/商店
我有几个网格，它们显示的数据并未真正映射到模型，例如统计数据、计数等。它们显示的值是由服务器根据当前登录的用户动态生成的，并且可能与任何数字相关服务器端模型。
针对这些情况设置 ExtJS 模型似乎很愚蠢。他们可能看起来像：
Ext.define('???', {
extend: 'Ext.data.Model',
fields: ['name', 'count']
});
这对我来说没有意义。我知道商店的 fields 属性仍然存在，但文档指出它只是为了向后兼容而存在，应该避免。另外，至少在兼容层运行的情况下，控制台会警告不要使用它。
那么针对这些情况的“正确”方法是什么？
I have several grids that display data that doesn't really map to a Model, e.g. statistics, counts, etc. The values they display are dynamically generated by the server based on the currently-logged in user, and could be related to any number of server-side models.
It seems silly to set up an ExtJS Model for these situations. They might look something like:
Ext.define('???', {
extend: 'Ext.data.Model',
fields: ['name', 'count']
});
It doesn't make sense to me. I know the fields attribute of the store is still there, but the documentation states it is only really there for backwards compatibility and should be avoided. Plus, at least with the compatibility layer running, there's the console warning against using it.
So what is the "proper" approach for these situations?

有类似的问题。 Sencha 声称在这种情况下可以使用“fields”属性。

Had a similar problem. Sencha claim that in such a case it's ok to use the 'fields' property.
