我试图根据用户是否是零售商来呈现不同的UI。我认为大多数情况都正确,但是在应用初始化时,我想检查用户是否为零售商(这将调度checkAuth
动作)。
我尝试运行以下命令以从Firebase获取isRetailer
属性的值。
firebase.database().ref('/users/' + user.uid + '/isRetailer').once('value').then(snapshot => snapshot.val()
然后我根据结果调度一些动作。由于某些原因,即使用户的
isRetailer
属性为true,我的Vuex状态的isRetailer
部分也不会从false更新。我不确定为什么,但是我猜测它与我的firebase参考有关。我的完整代码如下。谢谢!
import firebase from 'firebase'
const authentication = {
state: {
isAuthed: false,
authId: '',
isRetailer: false
},
mutations: {
authUser (state, user) {
state.isAuthed = true;
state.authId = user.uid;
},
notAuthed (state) {
state.isAuthed = false;
state.authId = '';
state.isRetailer = false
},
isRetailer (state) {
state.isRetailer = true
},
isNotRetailer (state) {
state.isRetailer = false
}
},
actions: {
checkUser (context, user) {
if (!user.uid) {
// Do nothing.
} else if (firebase.database().ref('/users/' + user.uid + '/isRetailer').once('value').then(snapshot => snapshot.val()) === true) {
context.commit('authUser', user);
context.commit('isRetailer');
} else {
context.commit('authUser', user);
context.commit('isNotRetailer');
};
},
signOut (context) {
context.commit('notAuthed')
},
setRetailer (context, payload) {
// Set retailer info in Firebase.
var uid = payload.user.uid;
firebase.database().ref('/users/' + uid).set({
name: payload.name,
email: payload.email,
location: payload.retailerLocation,
isRetailer: payload.isRetailer
});
},
setNewUser (context, payload) {
// Sets a user in firebase w/ a isRetailer value of false.
var uid = payload.user.uid;
firebase.database().ref('/users/' + uid).set({
name: payload.name,
email: payload.email,
isRetailer: payload.isRetailer
});
}
},
getters: {}
};
export default authentication;
最佳答案
发生这种情况的原因可能是您为突变和状态变量指定了相同的名称:isRetailer
,我现在没有任何引用,但是可能不会触发突变。您可以通过设置突变来尝试一次不同的名称,例如:
mutations: {
...
...
setIsRetailer (state) {
state.isRetailer = true
},
isNotRetailer (state) {
state.isRetailer = false
}
},
并在行动中使用它:
actions: {
checkUser (context, user) {
...
...
context.commit('authUser', user);
context.commit('setIsRetailer');
}
