如何从 then() 函数中获取 firestore 集合引用?
How do I get firestore collection reference from within then() function?
我正在使用 vuexfire 将 firebase 引用绑定到我的应用程序状态。
这很好用:
bindRef: firebaseAction(({bindFirebaseRef}, payload) => {
let firebaseRef = db.collection(`/${payload}`)
bindFirebaseRef('storeProperty',firebaseRef)
})
但是,我只想在成功获取后进行绑定;这样我就可以捕获错误并设置进度指示。
像这样:
bindRef: firebaseAction(({bindFirebaseRef}, payload) => {
let firebaseRef = db.collection(`/${payload}`).get().then(e => {
//where ref is same as firebaseRef
bindFirebaseRef('questions',ref)
})
})
您需要将对该集合的引用声明为变量,然后才能将其传递给您的函数:
bindRef: firebaseAction(({bindFirebaseRef}, payload) => {
let firebaseRef = db.collection(`/${payload}`)
firebaseRef.get().then(e => {
//pass firebaseRef to the function
bindFirebaseRef('questions',firebaseRef)
})
})
