Hi, how do I ignore some fields of model class when serializing to json with gson?

[wouterdoeland]

I think what you're looking for is transient

[avolkmann]

You have lots of options actually

[avolkmann]

Annotations, custom converters

[wouterdoeland]

@Transient

[wouterdoeland]

That's what Java wants you to use I think (@Transient is transient keyword in Java)

[aeruhxi]

I tried with Expose and

install(ContentNegotiation) {
        gson {
            setDateFormat(DateFormat.LONG)
            excludeFieldsWithoutExposeAnnotation()
        }
    }

It didn't work

[aeruhxi]

yup that's what I did

[aeruhxi]

or am I missing something in the gson block above?

[avolkmann]

@Transient works for me

[avolkmann]

just tried it

[avolkmann]

Expose also works as expected

[avolkmann]

data class Test(@Expose val id: String, val excluded: Int = 5)

[aeruhxi]

@avolkmann are you sending content with call.respond(Test("asd")) ?

[aeruhxi]

I also used Expose, but didn't work in mine

[aeruhxi]

data class User(
        val id: Long,
        val realId: Long,
        @Expose val firstName: String,
        @Expose val lastName: String,
        @Expose val profilePictureLink: String,
        @Expose val status: Int,
        @Expose val suspended: Boolean,
        @Expose val username: String
)

I have something like this

[avolkmann]

And what result do you get?

[avolkmann]

yes I use call.respond(Test)

[avolkmann]

also what version do you use?

My bad... Intellij was running the old compiled files for some reason. I had to rm out and build directory and ran it again and now it's working. Sorry for all the confusion and fuss. Thanks for trying to help.
