Array types

[yovanoc]

As you tell me @divyenduz I create an issue for a follow up on this one #256

Why array types are | null and not simple empty array?

[divyenduz]

@yovanoc Can you please provide an example?

I think it depends on the type (an array can be a nullable array (| null case) or a non-nullable array [] empty array case).

If I understand correctly, please share an example of what you mean.

I just sent you an email

[pantharshit00]

I checked this out and arrays are not | null

Also, the schema doesn't allow nullable array by design for the same reasons as you have posted.

Can you please send in the query or the screenshot where arrays are nullable?

I tested using prisma2@2.0.0-preview014.2, binary version: 237b46b97773f5018e336550e4285e2a78c38483

[yovanoc]

Ok now with latest alpha array are not nullable anymore, but an optional field in my schema in nested select is not marked as nullable.

PS: Schema and query in our mail conversation. thanks

[pantharshit00]

I can't reproduce. It is nullable. Also, as a side note please don't confuse ? operator with nullability. ? makes a property optional not nullable

[yovanoc]

You'are right I said nullability when a field is optional in the prisma schema and should be | null in the generated typescript no? I make a little reproduction tested with prisma2@2.0.0-alpha.266, binary version: 998508a3ac0132b0b211dec85419e0a27f3d1813.

Schema:

Query:

const userTest = await photon.userTests.findOne({
    where: {
      id: "Example"
    },
    select: {
      id: true,
      globalConfig: {
        select: {
          accounts: {
            select: {
              username: true,
              password: true,
              config: {
                select: {
                  data: true,
                  list: true
                }
              }
            }
          }
        }
      }
    }
  });

Result:

Here I don't get why accounts are marked as | null and the list of Random model too. But what I was telling you first was this AccountData? but yeah now it's good for that.

Thanks

[pantharshit00]

Oh yes, you are right. account and config.list should not be marked a nullable field.

I can confirm this as a bug now. Here is the reproduction for internal use: https://github.com/harshit-test-org/prisma-photon-259

[timsuchanek]

Fixed in latest alpha.
You can try it out with npm i -g prisma2@alpha.

[yovanoc]

Still happening to me on

[timsuchanek]

Please try again with alpha.278, sometimes the CI/npm takes a bit longer.
I just manually test it with 278 and it works for me.

[yovanoc]

AHAH yes thats PERFECT
