Prisma Docs not working as instructed for insensitive case search. 9am and my brain hurts.

    const serverTypes = ctx.prisma?.server.findMany({
      where: {
        published: true,
        nsfw: false,
        serverTypes: {
          has: input,
        },
      },
      orderBy: {
        votes: "desc",
      },
    });

    const serverTypes = ctx.prisma?.server.findMany({
      where: {
        published: true,
        nsfw: false,
        serverTypes: {
          has: input,
        },
      },
      orderBy: {
        votes: "desc",
      },
    });

I am using the input of a URL to then query my database, so for example Discord. This works correctly, however it doesn't work for lower case, such as discord. Looking at the Prisma docs (https://www.prisma.io/docs/concepts/components/prisma-client/case-sensitivity) it instructs me to to use mode: 'insensitive',. This does not work and the TypeScript error is as follows when placing the code under has: input,

Type '{ has: string; mode: string; }' is not assignable to type 'StringNullableListFilter'.
  Object literal may only specify known properties, and 'mode' does not exist in type 'StringNullableListFilter'.ts(2322)

Type '{ has: string; mode: string; }' is not assignable to type 'StringNullableListFilter'.
  Object literal may only specify known properties, and 'mode' does not exist in type 'StringNullableListFilter'.ts(2322)

I believe this is telling me because I don't have a mode in the database, it can't be used. Which makes sense? But then what is the correct way to filter case insensitive?

instead of has try contains https://www.prisma.io/docs/reference/api-reference/prisma-client-reference#contains the mode you're concerned about is this https://www.prisma.io/docs/reference/api-reference/prisma-client-reference#mode

actually, not sure what default of mode is (not using prisma rn)

I'm using Postgres, so by default it's case sensitive hence the issue. Same error using contains. I am the noob here so I am sure its something obvious I am not considering but got no idea..

const serverTypes = ctx.prisma?.server.findMany({
      where: {
        published: true,
        nsfw: false,
        serverTypes: {
          contains: "Discord",
        },
      },
      orderBy: {
        votes: "desc",
      },
    });

const serverTypes = ctx.prisma?.server.findMany({
      where: {
        published: true,
        nsfw: false,
        serverTypes: {
          contains: "Discord",
        },
      },
      orderBy: {
        votes: "desc",
      },
    });

Type '{ contains: string; }' is not assignable to type 'StringNullableListFilter'.
  Object literal may only specify known properties, and 'contains' does not exist in type 'StringNullableListFilter'.ts(2322)

Type '{ contains: string; }' is not assignable to type 'StringNullableListFilter'.

Is this just a TypeScript issue thing? Where it thinks there will be an error but Prisma handles it correctly? has does auto complete in vscode, contains and mode do not, so version? I got no idea

mrnicericee•2y ago

oh so the query goes through properly? also, i think there should be an await?

const serverTypes = await ctx.prisma?.server.findMany({
      where: {
        published: true,
        nsfw: false,
        serverTypes: {
          contains: "Discord",
          mode: "insensitive",
        },
      },
      orderBy: {
        votes: "desc",
      },
    });

const serverTypes = await ctx.prisma?.server.findMany({
      where: {
        published: true,
        nsfw: false,
        serverTypes: {
          contains: "Discord",
          mode: "insensitive",
        },
      },
      orderBy: {
        votes: "desc",
      },
    });

and if it's a typing issue maybe doing a typescript server reset is necessary cmd + shift + p -> Restart TS server

Tried that, tried reboot and all Will add the await! So, I tried it on a different query, it works fine! It seems because I store the data in an array, I'll have to lookup how to do it with those If its a string, these all work, if its an array, I guess not?

mrnicericee•2y ago

oh serverTypes is an array? and yeah, what we've been talking about was how to query a string

mrnicericee•2y ago

this part of the docs should help out @Debaucus https://www.prisma.io/docs/concepts/components/prisma-client/working-with-fields/working-with-scalar-lists-arrays

your original has was really close looks like

Not seeing something that would cover case sensitivity 😦 Even chatgpt keeps spitting out use raw which 1 is bad and 2 doesn't work a raw isn't an accepted value here either!
