Received HTTP 422 from booru: 'PostQuery::TagLimitError'

[Hatsune-Mikun]

Hello! It's me, again c:

I got this error while trying to get 1 post from danbooru with tags: angel, white_hair, rating:safe

await Booru.search(site, tag, { limit: 1, random: true }).then(posts => posts[0])

I guess isn't your issue, is it API, but anyway, can you recommend something or do with this?

[AtoraSuunva]

Using random: true will make booru add order:random to the tags before searching, so you'd have to disable random (random: false) and select a random result yourself

https://github.com/AtoraSuunva/booru/blob/master/src/boorus/Booru.ts#L166=

I could add a fakeRandom option that would use the same logic for boorus that don't support order:random (fetch 100 results, then sort them randomly)

[Hatsune-Mikun]

Sounds like a good solution to create a minor update

But doesn't danbooru support random? It always worked with a large number of tags and randomly before, the problem arose only on these tags, which was shocking for me, so i'm here

[Skitteyy]

So is this gonna be a thing or not?

[AtoraSuunva]

@Hatsune-Mikun danbooru does support order:random, but it seems to make the database time out often for some reason

Danbooru also does not let you search using more than 2 tags unless you have a paid account

@Skitteyy I was planning to add it in to the rewrite of booru, but I've been busy updating my other code first

If you have a use for this right now I can try adding it in

[Hatsune-Mikun]

I take a big break on programming because depression, so you can make it when it gonna be comfortable for you, and i just update it after, i will use you library anyway

[Skitteyy]

Ah I see. No worries

[Skitteyy]

Well I don't know if anything will happen but I use booru for my discord bot and I found out that you can put a limit of 100 when you search with 2 tags and then put something like
"const random = Math.floor(Math.random() * 100) +1"
and then put image.posts[random].file_url instead which will get you a random post of 100, but it sometimes just says
"Cannot read properties of undefined (reading 'file_url')".

Seems to also error sometimes when searching with only one tag

[AtoraSuunva]

@Skitteyy You're probably searching tags that have less than 100 results, which then makes random go out of bounds and you get undefined

You'll need to generate a random number based on the number of search results:

const random = Math.floor(Math.random() * post.images.length)
const image = post.images[random]

I see, works perfectly, thanks
