Hi, guys! I'm entirely new to the kotlin (by extension, ktor) ecosystem and I'm building the server-side logic for an existing client application. Using exposed ORM, I'm trying to use a datetime field but when I use the datetime function, it keeps throwing unresolved reference: datetime . I've also added the exposed-java-time to my dependencies.

[hallvard]

Could it be that you also need the kotlinx-datetime dependency? (https://central.sonatype.com/artifact/org.jetbrains.kotlinx/kotlinx-datetime/0.4.0/versions)

[Manasseh]

I've also tried this but same error. Here's what my dependencies list looks like

[hallvard]

I see you're using Idea, so try File->Invalidate caches. Otherwise, I'm out of suggestions, I'm afraid ...

[Emil Kantis]

you shouldn't need kotlinx-datetime. But you would have to reload gradle (little icon hovering with the elephant in your editor)

[hallvard]

Yes, or alt+shift+O

[Manasseh]

alt+shift+O doesn't work for me. I use a Linux

[hallvard]

Sorry, that's CTRL+shitf+O. My bad.

[Manasseh]

Still doesn't work

[Manasseh]

I've invalidated my caches severally. But the error keeps returning

[hallvard]

What do the imports and uses look like in the file where this error occurs?

Try importing kotlinx.datetime.Instant and replace your call to datetime with something like Instant.fromEpochMilliseconds(time()).toLocalDateTime(timezone)

[Emil Kantis]

Are you trying to use DateTime from kotlinx-datetime or java.time?

[Manasseh]

How do I use both?

[Manasseh]

@hallvard now it shows unresolved reference: timezone

[Emil Kantis]

you shouldn't use both.. Either you're dealing with a multiplatform project and should use kotlinx-datetime, or you're dealing with a JVM project and should use either (though I would prefer java.time since it's stable and interoperable with other libraries on the JVM)

[hallvard]

You were missing an import, I think. Disregard my suggestion, follow Emil's advice, but do remember to import the stuff you use.

[Emil Kantis]

And you should use the exposed dependency for the time-handling lib you choose. so either exposed-java-time or exposed-kotlin-datetime

[Emil Kantis]

IF you end up using exposed-java-time, this import should do the trick:

import org.jetbrains.exposed.sql.javatime.datetime

[Manasseh]

Thank you very much. It works now

[Manasseh]

Thanks guys for the assistance

[Manasseh]

I was wondering if there's a reference documentation I could use to find certain import statements I can't recall by heart.

[hallvard]

Won't Idea mostly suggest them for you? If you mouseover or something?

[Manasseh]

For the datetime problem, and some others, It didn't

[Emil Kantis]

It should have.. Could be a problem with the IntelliJ cache as @hallvard suggested earlier 🙂

[Manasseh]

I see.. so frequent cleanings then.

[Emil Kantis]

It should not happen regularly. 🙂

[Manasseh]

I see.. ok then

[Manasseh]

This is unrelated, but didn't think to create a new thread. I was wondering what password hashers are available in ktor? I've tried ktor-features and jbcrypt but none seems to work for me @hallvard @Emil Kantis

[Emil Kantis]

I have no idea 😞

[hallvard]

Sorry, I am just as ignorant as you are on this.
