export const eventCreate = ({ title, time, location }) => {
const newPostKey = firebase.database().ref('/events').push().key;
const update = {};
const postDetails = {
eventId: newPostKey,
title,
...
goingNumber: 1,
...
};

.update(update)
.then(() => {
dispatch({ type: EVENT_CREATE });
})
.then(() => newPostKey);
};
};
數據庫
:
export const eventSave = ({ goingNumber, eventId }) => {
return (dispatch) => {
firebase.database().ref(`/events/${eventId}`)
.set({ goingNumber })
.then(() => {
dispatch({ type: EVENT_SAVE_SUCCESS });
});
};
};
我得到這個錯誤說:
