03:15 <riffraff169> im still learning crystal, wont be able to talk, but would like to attend

07:31 <FromGitter> <ilourt> Hi all,

07:33 <FromGitter> <ilourt> I'm using Granite as an orm. I want to have a base model class (with columns) and then use it by inheritance in other models. The problem is that I have the following error linked with granite: `Error: class variable '@@validators' of App::Models::BaseModel is already defined as Array(NamedTuple(field: String, message: String, block: Proc(App::Models::Zone, Bool))) in App::Models::MyModel`

07:34 <FromGitter> <ilourt> Someon have any idea how I could achieve inheritance with Granite ORM?

08:26 <FromGitter> <grkek> How does one pass a function as an argument?

08:26 <FromGitter> <naqvis> @grkek use `Proc`

08:26 <FromGitter> <grkek> Understandable

08:26 <FromGitter> <naqvis> or you can use block

08:26 <FromGitter> <grkek> Do you know any block magic?

08:27 <FromGitter> <naqvis> in what sense?

08:27 <FromGitter> <naqvis> btw you can pass methods as block as well

08:27 <FromGitter> <grkek> Cool tricks with blocks

08:27 <FromGitter> <grkek> Hm how do I do that?

08:27 <FromGitter> <naqvis> just prepend `&`

08:29 <FromGitter> <grkek> Why can't setter methods use blocks?

08:30 <FromGitter> <grkek> Can you show me an example of passing a function in a block?

08:32 <FromGitter> <naqvis> https://crystal-lang.org/reference/syntax_and_semantics/block_forwarding.html

08:59 <FromGitter> <j8r> there is also `my_func &->other_func`

09:02 <FromGitter> <Dan-Do> > Can you show me an example of passing a function in a block? ⏎ ⏎ macro `content_for` in kemal uses block

09:12 <FromGitter> <naqvis> @ilourt don't know Granite, but a quick look at their code base revealed that, `Granite::Base` isn't designed to be used in your use-case. Both Base and `Validators` have defined macro `inherited` hook, which got executed during compilation time, and causes the code inside those macros to get added to classes.

09:12 <FromGitter> <naqvis> For your use-case you might try to composition approach other than inheritance heriarchy

09:35 <FromGitter> <ilourt> @naqvis thanks for your answer. It is very annoying that we can not use the base of the OOP. The problem is that there is no real good orm in crystal :(

09:36 <FromGitter> <Dan-Do> what db are you using?

09:36 <FromGitter> <ilourt> postgres

09:37 <FromGitter> <Dan-Do> fair enough, I am using nosql, which return JSON, so easier :)

09:38 <FromGitter> <ilourt> ;) In this case I have no choice but to use sql

09:48 <FromGitter> <naqvis> I haven't tried, but don't know if you had looked into https://github.com/ysbaddaden/rome

11:07 <FromGitter> <Nicolab> Look nice rome ORM

11:48 <mps> looks like crystal have issue with futex https://www.openwall.com/lists/musl/2020/10/28/10

12:47 <FromGitter> <wyhaines> @ilourt Have you looked at Jennifer? https://github.com/imdrasil/jennifer.cr

12:56 <FromGitter> <Blacksmoke16> @ilourt see https://github.com/amberframework/granite/issues/358

15:43 <FromGitter> <ImAHopelessDev_gitlab> hi

15:44 <FromGitter> <Blacksmoke16> o/

15:48 <FromGitter> <ImAHopelessDev_gitlab> how have you been, @Blacksmoke16 ?

15:49 <FromGitter> <Blacksmoke16> not too bad

16:15 <FromGitter> <RespiteSage> @mps Is that likely to be a Crystal problem rather than an LLVM problem?

16:16 <FromGitter> <RespiteSage> Oh, well it looks like Zig is an LLVM language, and that works...

16:42 <mps> RespiteSage: same llvm but with musl 1.2.0 works fine

16:42 <mps> musl 1.2.1 exposed a lot of buggy software around

16:43 <mps> because musl 1.2.1 is strict about MT-unsafe 'working'

20:37 <FromGitter> <rishavs> What's the latest and greatest in the Crystal ecosystem for hot reloading. I remember Sentry was the big one a few years ago.

20:37 <FromGitter> <Blacksmoke16> i just use nodemon

20:48 <FromGitter> <rishavs> thats revelatory. I never knew nodemon could also monitor cystal projects. Thanks

21:01 <FromGitter> <Blacksmoke16> `nodemon --exec crystal run --watch src` is what i do

21:04 <sampope> anyone have experience/pointers on using Time.format for RFC 3339? I cannot seem to wrap my head around the api call, ```https://crystal-lang.org/api/0.35.1/Time/Format/RFC_3339.html```

21:07 <FromGitter> <rishavs> Thank @Blacksmoke16 . `nodemon --exec "crystal run" src/kaipi.cr --watch src -e cr,ecr,md,json` works well for me

21:08 <FromGitter> <Blacksmoke16> 👍

21:10 <sampope> here's a code snippet, https://dpaste.org/74Fg

21:13 <sampope> time.to_rfc3339 doesn't exist, and reading the rfc3339.cr source isn't helping me

21:14 <FromGitter> <Blacksmoke16> whats the goal here? just trying to output a string in rfc3339 format from a `Time` object?

21:15 <FromGitter> <Blacksmoke16> `timestamp.to_rfc3339 fraction_digits: 3` ?

21:15 <FromGitter> <Blacksmoke16> https://play.crystal-lang.org/#/r/9wda

21:17 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/master/Time.html#to_rfc3339(*,fraction_digits:Int=0)-instance-method

21:22 <sampope> thanks @Blacksmoke16, i must be dumb today, i could swear timestamp.to_rfc3339 failed repeatedly for me in the playground

21:23 <sampope> of course, now ```puts timestamp.to_rfc3339(fraction_digits: 3)``` works fine. ugh

21:24 <FromGitter> <Blacksmoke16> :p

21:24 <FromGitter> <Blacksmoke16> Np
