I'm trying to update multiple paths at the same time with my Firebase database, but each path requires variables to define:
const update_referral_path = "referrals/" + referral_code.trim() + "/" + current_user_id
const new_referral_path = "profile/" + current_user_id + "/user_dict/profile/referral_code"
I'm using this code to update it, but Firebase as expected updates the database with the literal string "update_referral_path" and "new_referral_path."
admin.database().ref().update({
update_referral_path: current_time,
new_referral_path: generated_referral_code
}, error => {
if (error) {
console.log("updateReferral failed")
return false
} else {
console.log("updateReferral succeeded")
return true
}
})
I've seen ways to use variables in Angular with backticks and double brackets, but I'm unsure how I can do this in vanilla JS and can't find any examples of people doing so? What are my options?
To use the value of the variable in a key, use [] notation:
admin.database().ref().update({
[update_referral_path]: current_time,
[new_referral_path]: generated_referral_code
}, error => {
...
You can also build a literal JSON object outside of the update call:
let updates = {};
updates[update_referral_path] = current_time;
updates[new_referral_path = generated_referral_code;
admin.database().ref().update(updates);
