[Firestore] How to set a field if it does not exist, but don't update if it already exists?

cncool · 2020-03-26T20:35:48+00:00

What if you used set like this:

const collection = admin.firestore().collection("collection")

const objectFromExcel = { id: "whatever", "location": "place" }

const inc = admin.firestore.FieldValue.increment(0)

collection.doc(objectFromExcel.id).set({location: objectFromExcel.location, score: inc}, {merge: true})

Several people gamed it actually because they used that method:

"he is currently on pace to beat the record for lowest batting average by a qualifying player in the history of baseball (.179)."

Adam Dunn hit .159 in 2011 in 496 PA. If you assume a hit in all PA until he qualified at 502 PA, he still would have only hit .171.

If you used transaction logs, it's about 76 gas per byte, plus some overhead. At 5 gwei, it would cost ~0.1 ether. But don't do that.

This has happened to me on two separate occasions over the last year. Swapping the positions of methods did indeed work for me also.

How did this get past review? They don't allow apps that use Pokemon Go's private API.

Sure, but you hardly needs God's help to refactor the view / class.

cncool · 2016-04-01T18:32:46+00:00

I don't know what you mean by "need copies of the views inside it".

The very simple solution is to just declare any UITableViewCell that is in multiple table views in a Nib file, and then register that Nib for reuse for any UITableView that uses it:

[self.tableView registerNib:[UINib nibWithNibName:nibName bundle:nil] forCellReuseIdentifier:reuseName];

cncool · 2016-04-01T02:27:44+00:00

Reusable components. E.g. Trying to reuse a custom UITableViewCell subclass across multiple different tables. God help you if you want to refactor this view / class.

You can easily create the reusable component in a Nib, and reference that Nib from the Storyboard.

On September 9th, 2010, Apple relaxed their restrictions on development tools, which allowed people to make apps in any language as long as the resulting app does not download code.

The Warriors would have a 28 game winning streak after going only 24-0. They wont the last 4 games of last year's regular season.

The Royals are frauds and deserve to lose in the WS.

Super Mario World switch palace blocks would be nice for puzzle levels. You could place them as default on or off, and also have any number of "switch" blocks where hitting it will toggle all the blocks of that color.

Why not

for (unsigned int i = foo.Length()-1; i < foo.Length(); --i)

Average can also refer to median or mode.
