Issue with UK enum value

[guydunton]

I've found an issue with generation when an enum contains the value UK. e.g.

enum DeploymentRegions {
  EU
  UK
}

I get an error which looks like:

Command failed: "/Users/test/Documents/dev/api/node_modules/.bin/mmdc" -i "/var/folders/ky/5jpl226x1671bz_34h02wwg40000gn/T/prisma-erd-EtD1ko/prisma.mmd" -o "/Users/test/Documents/dev/api/prisma/ERD.svg" -c "/var/folders/ky/5jpl226x1671bz_34h02wwg40000gn/T/prisma-erd-EtD1ko/config.json" -p "/var/folders/ky/5jpl226x1671bz_34h02wwg40000gn/T/prisma-erd-EtD1ko/puppeteerConfig.json"

Running the command I get:

It looks to be related to mermaids using UK to indicate unique key (link).

We've gotten around it by disabling enum generation but a fix would be nice, either by escaping the value in the .mmd file (I couldn't see if this was possible) or by moving away from mermaids (as a fix to #102)

Most of the time its a mermaid thing. I'll see if I haven't wrapped enums in quotes already. That's typically the route to get around some mermaid specifics.

[keonik]

Gave it a shot and it looks like the enums were not wrapped in quotes already. When I wrote out a schema

generator erd {
  provider = "node ./dist/index.js"
  output   = "../../__tests__/238.png"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model Deployment {
  id        String   @id @default(uuid()) @db.Uuid
    region DeploymentRegions
}

enum DeploymentRegions {
  EU
  UK
}

and ran locally with the quotes I was still getting an error. As it turns out the enums are not something you can wrap in quotes. All cases started to fail afterwards that used enums. I did get the above to pass by switching UK to anything else so it might be a reserved word for mermaid.

What could be done is

• Disabling enums in the output

generator erd {
  ...
  ignoreEnums = true
}

• Asking maintainer to overwrite UK to U_K or something of that variety

What are your thoughts?
