Firebase Firestore Tutorial - Data Model (Lesson 2)

How does Firestore store its data? In this Firestore Tutorial video, I'll show you how to structure and organize your data in a Firestore database.
Your database is essentially "Collections of Documents".
What's a Collection?
It's a group of documents plain and simple.
What's a Document?
A Firestore Document stores your actual data in pairs containing a Field and a Value. Here's the trippy part: a document itself can contain Collections of other Documents! This nesting can go on for 100 levels deep.
To see this stuff in action, watch this Firebase tutorial where I'll dive into a Firestore database backend and show you Collections, Documents and all of the various data types you can store!

I'm working with Android from last 2 year. It was a long plan to start learning iOS(Swift + Xcode) but due to lack to free quality content it was complex for me. Thanks god, I found you on KZfaq. Your videos are beginner friendly, easy to follow & most importantly its free. I won't mind to pay for advanced iOS development series if you have any. Thanks you so much for making for iOS learning life easier :)

Hey Chris, I want to make a game and I would like my app to keep information like best score and amount of coins (game money). How can I do that? Cause every time I close the app and re open it again, I lose the information. Thanks a lot and keep doing the great videos! They are very helpful!

Hello, i suggest you look into database for this so your information gets saved, i suggest go for firebase (kzfaq.info/get/bejne/hrOSpNJo2svDpWQ.html , this is the old tutorial a bit outdated but it will be great as reference) or realm kzfaq.info/get/bejne/htOjfbpmntiyiWw.html - Francis

I understand if this is too late for you to reply, but how would I access the nickname (from your example above) of the current user of my app?

@CodeWithChris 4 жыл бұрын

if you want to put user data on your app then you should make an entry in a users table (save nickname, lastname, firstname, birthdate, etc) and then just pull it if the login (lets say username or email) matches the one that he typed - Francis

Can you store text paragraphs in document fields of string type? I mean can you have multiple lines of text in it, with some sort of line breaks? Or is it only for a single line of text?

@CodeWithChris 4 жыл бұрын

Hello, the data should be saved as a long string, maybe you can save it along with the formatting like , , etc. and see if that works for you - Francis

@AlexPetrov108 4 жыл бұрын

Thanks for the tip about the formatting options. Later I found that I need to have " " for line breaks and " " for Windows line breaks in the text data I read from a txt file into a String variable. Or in other words, if I read a multiline text data from a txt file into a single String variable it will be automatically stored with those kinds of line breaks and can be displayed as multiline label when the number of lines is set to 0

Hello, Chris. can I use the same document id in the parent collection for the document ID in the sub collection? That means even though you have so many sub-collection in one parent collection, their document ids are the same. Can I ?

How can I create Unique Usernames with Firebase, I've been looking all over the internet for information on this? Anything info helps!

@CodeWithChris 3 жыл бұрын

Hello, if you. meant for authentication then there an option for email or some other things, it should be able to create any accounts made automatically. or you can make a "users" table and create your own list of authenticated users - Francis

@TheNamesJT 2 жыл бұрын

I wish he would of use better naming convention for this because a and doc a doesn't help me visualize a real scenario like the one i'm having trouble with. Basically on the home page I want to load user data so in a user collection each user would have a collection and eventually would like to load every user collection on the home page. Also that random id for each document is confusing as well. So if you plan on having multiple users is each document a user? so when there are multiple users you would have a collection names users and each document is 1 user and when a new user gets added to the db it creates a new document?

you might want to give an example on how to actually do it in firestore, like converting relational database into this firestore database that would be much better instead of a, b that has no actual representation.

using the a and b format really didn't help me a SQL programmer because it didn't give me context. We are all about relationships and structure so if you made it a more real scenario I would have been able to connect the dots...this is probably excellent for someone fresh into databases.

Hello, google should automatically do this for you, only the apps (com.sample.sample) set in firebase will be able to access your database, not to mention it also needs the config file provided by firebase to continue, so i think its pretty safe. unless they hack your app itself and manipulate the data inside it then your safe - Francis
