[2017-04-21T05:12:47-0500] <ultra-> Can someone help me update a database record in firebase?  I’m using the docs, but I’m having a hard time wrapping my head around it.
[2017-04-21T05:13:51-0500] <ultra-> I have “users” to hold all users, then “user” for their unique ID, and I want to add a node called “favorites” where multiple key/value pairs can be stored

[2017-04-21T05:22:38-0500] <arietis> ultra-: How about this one? http://stackoverflow.com/questions/39323906/swift-firebase-one-to-many-example
[2017-04-21T05:23:55-0500] <ultra-> This will help in the future when I need to relate the data (bookmarked), but I need to add the records
[2017-04-21T05:24:15-0500] <davidvs> you probably want to create a new key in root called favorites > userID > ...
[2017-04-21T05:24:19-0500] <ultra-> I know how to add a new user, I just don’t know how to add a node and new data to the node
[2017-04-21T05:24:26-0500] <davidvs> firebase is all about flattening the structure
[2017-04-21T05:24:43-0500] <ultra-> I have /users/user, I want /users/user/favorites and then multiple key/value pairs in favorites
[2017-04-21T05:24:47-0500] <davidvs> ok

[2017-04-21T05:25:19-0500] <davidvs> so you'd do users.child(userId).child("favorites").update([key: value])
[2017-04-21T05:25:37-0500] <davidvs> or set([key: value]) if you want to overwrite the entire location
[2017-04-21T05:26:11-0500] <davidvs> but if you're accessing arbitrary favortes by user id, you'll want to create a favorites key on root
[2017-04-21T05:26:16-0500] splendor (~splendor@2605:a601:1100:7100:1c70:55c5:ab00:d06) joined the channel
[2017-04-21T05:26:26-0500] <davidvs> otherwise you have to download the entire user node to get to the favorites
[2017-04-21T05:26:36-0500] <ultra-> will that automatically create the “favorites” node if it doesn’t exist?
[2017-04-21T05:26:41-0500] <davidvs> yes
[2017-04-21T05:26:43-0500] <davidvs> it just works
[2017-04-21T05:26:49-0500] <davidvs> you can't have an empty node
[2017-04-21T05:27:02-0500] <ultra-> well, favorites is the primary information I want anyway, so there won’t be a lot of data
[2017-04-21T05:27:13-0500] <davidvs> foo.child("bar").child("baz").child("value") creates all the subnodes
[2017-04-21T05:27:25-0500] <davidvs> still
[2017-04-21T05:27:33-0500] <davidvs> flatten it as much as possible right now to avoid headaches later
[2017-04-21T05:27:39-0500] <davidvs> it's nosql

[2017-04-21T05:28:56-0500] <ultra-> if I create a favorites key on root, what does the data structure look like?
[2017-04-21T05:29:14-0500] <ultra-> Essentially, I use the user to retrieve their favorites, and possibly a small amount of other information
[2017-04-21T05:30:13-0500] <davidvs> favorites > userId > whatever
[2017-04-21T05:30:20-0500] <davidvs> base everything off the user id
[2017-04-21T05:30:33-0500] <davidvs> that allows you to set firebase rules easier, too
[2017-04-21T05:31:10-0500] <ultra-> ok, so I access the favorites from favorites using userid as the key
[2017-04-21T05:31:16-0500] <davidvs> right
[2017-04-21T05:31:48-0500] <ultra-> and under users/user, i’d just keep the other information i want, such as their email address
[2017-04-21T05:31:54-0500] <davidvs> yeah
[2017-04-21T05:32:20-0500] <ultra-> This makes sense then… thanks a lot
[2017-04-21T05:32:51-0500] <davidvs> firebase is amazing but the 'structuring data' docs need more examples
[2017-04-21T05:33:47-0500] <ultra-> Yeah, and it needs continuity… the examples for adding new data and updating data don’t seem to relate too well
[2017-04-21T05:34:15-0500] <davidvs> are you doing web, ios or android
[2017-04-21T05:34:23-0500] <ultra-> but i can see how firebase is gonna be great once i get it down
[2017-04-21T05:34:43-0500] <ultra-> ios and eventually android, small chance of web in the future but for now I’m just building my iOS app
[2017-04-21T05:34:51-0500] <davidvs> ever since google acquired them they've been rock solid
[2017-04-21T05:35:04-0500] <ultra-> I’m not a programming professional and it’s just a hobby, so i don’t know where this will go
[2017-04-21T05:35:05-0500] <davidvs> ah good ios is a cinch
[2017-04-21T05:35:15-0500] <davidvs> plus it's cheap as shit now under the new pricing plan
[2017-04-21T05:35:23-0500] <davidvs> i have thousands of users and pay like $30 a month

[2017-04-21T05:36:00-0500] <davidvs> make sure to use FirebaseQuery to keep your data transfers low
[2017-04-21T05:36:09-0500] <ultra-> does your app have a one time cost or do you get constant revenue from the users?
[2017-04-21T05:36:29-0500] <davidvs> subscription model
[2017-04-21T05:36:41-0500] <davidvs> it's the only way to go nowadays
[2017-04-21T05:36:48-0500] <davidvs> even if it's like $5 a year
[2017-04-21T05:37:01-0500] <ultra-> yeah… I just don’t know how to work that out
[2017-04-21T05:37:27-0500] <ultra-> i hate the business and marketing side of it all, i just want to build things

[2017-04-21T05:38:35-0500] <ultra-> also, i’m using a free api and i don’t know if i’m allowed to monetize the data i get from it
[2017-04-21T05:40:10-0500] <ultra-> I’m essentially pulling in data from it, and then making it more useful by adding other information and ways to organize it
[2017-04-21T05:40:42-0500] <davidvs> the cool thing about firebase is that with the rules, you can make all that information publically accessible within your firebase
[2017-04-21T05:40:54-0500] <davidvs> so individual clients don't have to fetch anything from the API at all

[2017-04-21T05:41:23-0500] <davidvs> as long as someone can call the API or scrape the website and update the firebase, the clients are none the wiser
[2017-04-21T05:41:51-0500] <davidvs> it looks like your own data, from their POV
[2017-04-21T05:42:41-0500] <ultra-> Yeah, in certain ways I’ll be doing that to replace certain information with my own
[2017-04-21T05:42:44-0500] <davidvs> so if they revoke your api token, fuck them, make a new one
[2017-04-21T05:42:50-0500] <ultra-> or append information to theirs
[2017-04-21T05:43:26-0500] <ultra-> Also, their website doesn’t allow users to change information when needed, and I figure I’d allow that as a feature

[2017-04-21T05:43:51-0500] <ultra-> So at some point I might just dump all theirs into mine, and eventually it’ll change enough so it’ll be my own
[2017-04-21T05:43:56-0500] <davidvs> cool
[2017-04-21T05:43:57-0500] <davidvs> yep

[2017-04-21T05:44:25-0500] <davidvs> at some point you'll have to learn node to automate all that
[2017-04-21T05:44:51-0500] <davidvs> spinning up a heroku dyno is relatively cheap though
[2017-04-21T05:45:09-0500] <ultra-> Well, I do understand how to retrieve and structure their JSON data, and I can do it with large groups of data at once
[2017-04-21T05:45:29-0500] <ultra-> so I might have to do it 50 times, once for each state

[2017-04-21T05:47:14-0500] <ultra-> ok, i’ll add that into my bag of tricks too
[2017-04-21T05:47:16-0500] <davidvs> you can set the intial query , then it gets updated atomically whenever anything changes
[2017-04-21T05:47:25-0500] <davidvs> as opposed to fetching the entire tree every time you want to refresh the data
[2017-04-21T05:47:32-0500] <ultra-> that is awesome
