TypeError: Cannot read property 'length' of undefined

[ghost]

Hello,

got this error when run npx prismix command. But don't know where it comes from. I am using nx for monorepo, the config json file:

{
    "mixers": [
        {
            "input": [
                "./prisma/base.prisma",
                "./prisma/address.prisma",
                "./prisma/authentication-method.prisma",
                "./prisma/brand.prisma",
                "./prisma/card.prisma",
                "./prisma/channel.prisma",
                "./prisma/comment.prisma",
                "./prisma/country.prisma",
                "./prisma/file.prisma",
                "./prisma/like.prisma",
                "./prisma/permission.prisma",
                "./prisma/product.prisma",
                "./prisma/promotion.prisma",
                "./prisma/review.prisma",
                "./prisma/role.prisma",
                "./prisma/source.prisma",
                "./prisma/user.prisma"
            ],
            "output": "./prisma/schema.prisma"
        }
    ]
}

and some example codes of the schema files, is that done correctly?

role.prisma

@jamiepine This exception occurs in the function renderAttribute at this line:

return idFields.length > 0 ? @@id([${idFields.join(', ')}]) : '';

because idFields is undefined. Looking up the stack a bit I see that the code expects there to be an idFields property on the DMMF.Model class, but there is none. I'm wondering if this is due a to version skew: i.e., prismix is based on an older definition of DMMF.Model?

@blevine seems to be right., I did find this commit https://github.com/prisma/prisma/commit/c94f0e91bc0e87e4765a67dddd40a36251faae87 where idFields has been renamed to primaryKey

For the people looking for a quick fix :

• Clone this repo
• yarn install && yarn run build
• In your project run yarn add file:/path/to/prismix (only for yarn)

You should then be able to use prismix

[jamiepine]

I pushed a hotfix to prevent it erroring (1.0.18). Looking into Prisma's changes it isn't entirely clear how primaryKey is supposed to replace idFields as the only value of primaryKey I can see is null, will look into this further later.
