I have a firebase database where I am storing records. Is there anything already existing features in firebase by which I can use/compose a form to make entries to the database?
The Firebase console has a panel where you can see and manipulate the data in your Firebase Database. But beyond that, there is no functionality in the SDKs to help you build edit forms.

I’m developing an app in swift by using firebase in the back end.
I have successfully created a user by using the standard procedure as stated in the documentation.
My problem comes when I want to add the UID value to the database. I can’t. What I’m doing is getting the UID (userID) from the Auth().user (what I successfully do) and using the following code (I don’t have de computer do it can contain errors but I copy it from the documentation and I’m fact it compiles, the problem is that is does nothing
let ref = Database().database().reference()
self.ref.child(“users”).setValue(userID)
I have tried with the following
Self.ref.child(“users”).child(user.id).setValue(userID)
But it fails due to the fact that users have no children. The issue is that users is a collection and I don’t now if it works in the same way or not.
My intentions is to create the entry in the “users” collection in the database just after singing up a new user. (And to be able to layer erase it)
Thanks!
Firebase has two NoSQL databases:
the Realtime Database, which is the original JSON database.
Cloud Firestore, which is the newer document/collection database.
These two databases are both part of Firebase, but have completely separate APIs.
You speak about collections in your question, which are a Cloud Firestore concept. But your code uses the API of the Realtime Database. If you're looking to write data to Cloud Firestore, you'll want to use the API that is documented here.
I am creating a mobile app , and this mobile app works currently with one google fire store database.
I want to see this app to more than one customer and I don't want to make a collection for each customer.
Instead I want to open a new database.
I know that I need to import the JSON file for each database.
My Question:
Can I tell the app to use database one then if you login with another
account use database 2?
There is only a single Firestore database instance per Firebase project. There is (currently) no way to add additional Firestore database instances to a project.
So that means you'd have to have a separate project for each user. That part is technically feasible for databases, as you can dynamically create a FirebaseApp instance with the configuration data for the signed in user. The problem is that you need to first sign in the user (which requires that you already have a FirebaseApp instance for the project that this user is registered on.
I'd highly recommend reconsidering why you want to create a separate Firestore instance for each user, as creating user-specific sub-collections is by far the simplest way to implement a multi-user application on Firestore.
How to sync data between MySQL server and Sqflite in flutter? I just want to integrate the offline mode in my flutter app...
Is there any library for this?
Unfortunately, there is no library for this. But, it should be pretty straight forward to implement. Just follow these 3 points:
1) Create a function for initial upload of data on SQFLite on from MySQL database when for eg: when a user enables offline mode, or logins for the first time, etc. whatever is relevant to your use case.
2) Then you have to have another function which when the user is online, checks if SQFLite data is in sync with MySQL, if not it updates SQFLite database (This step is unnecessary if the MySql database for the user can only be modified by the user, in which case just the 3rd point is sufficient)
3) Another function is required where when the user changes MySQL data(read, updated, deletes), SQFLite data is updated by recent MySQL data.
If you know basic querying of MySQL and SQFlite (which is quite similar) and are familiar with deserializing data, this should be easy to implement.
Can't find any option to import my SQL Database into Firestore database.
Realtime Database has this function, for example.
Is it suggested to be available in Firestore after the Beta ?
I don't think there is a direct import right now.
You have a few options though:
Use the Firebase libraries to export data from your SQL application into Firestore manually (alternatively write a cloud function and get the data via an API). This can also be a good option, if you need to keep both DBs in sync for some transition time.
If you need to get your user accounts over to Firebase Auth, read this article
If you already have your data in a Firestore, gcloud now has an import in beta (https://firebase.google.com/docs/firestore/manage-data/export-import)
From your description I fear that the first option is the way to go for you. Unfortunately Firestore is still in beta and we have to create a lot of functionality ourselves (like SQL imports, data migrations, test mocks, …).
I will try to explain the context of the project on which I'm working and the problem which I currently try to overcome. I would like to collect mobile data for analytics purpose, e.g. using Firebase from Google. After collecting thoses data, I'd like to store them in a local database, such as PostgreSQL or MongoDB. But the thing is mobile data collecting platform such as Firebase mostly doesn't support connecting to a local database. I've found out that there is a possibility to export raw data from Firebase to import into a local database, but I have no detail information about this. I've searched through many documentations and I couldn't find anything.Has everyone ever had this kind of problem and can give a clear guidance about exporting data from Firebase and import into a local database? Thanks in advance.
Google Analytics for Firebase collects enormous amount of data and send it to the servers in form of batches or bundles. Three things here with your design:
SDK collects that data and does not expose it for you to parse in the app and store it in local DB.
Storing this much data locally, you are going to re-invent the wheel. In addition, this could cause performance issues.
If you need all the data collected by Firebase in raw form, just link Firebase to Big Query and all data would be available to you.
