useForm的bug

[w2ichan]

declare function useForm(modelRef: Props, rulesRef?: Props, options?: {
immediate?: boolean;
deep?: boolean;
validateOnRuleChange?: boolean;
debounce?: DebounceSettings;
}): {
.......
};

function useForm(modelRef, rulesRef, options) {
var initialModel = cloneDeep(modelRef);
var validateInfos = {};
Object.keys(rulesRef).forEach(function (key) {
validateInfos[key] = {
autoLink: false,
required: isRequired(rulesRef[key])
};
});
......
}

rulesRef为非必填参数，但是useForm方法中，却没有判断rulesRef是否为undefined，直接进行Object.keys操作....这样会报错~

目前有解决办法

useForm(modelRef, reactive({}));

rulesRef必须为reactive对象，直接使用空对象会有警告，这是由于
watch(rulesRef, function () {
if (options && options.validateOnRuleChange) {
validate();
}
}, {
deep: true
})

这一段代码导致，所以watch必须是一个reactive对象，
