camelCase plugin with a strangely named column

We have a column named cl_companyID (I'm as confused as you) and I have issues with the camelCase plugin because it thinks the name is cl_company_id. Is there a way around this, without renaming the column? I was thinking maybe we could add support with some kind of lookup table with weird names for the plugin to respect.

Solution:

Something like ```ts class MyCamelCasePlugin extends CamelCasePlugin { protected override snakeCase(str: string): string {...

You can extends the plugin and override the snakeCase and camelCase methods.

We also have one: cl_LID_c 🥲 "I like snake case but I also like pascal case but also snake case is good"

Something like

class MyCamelCasePlugin extends CamelCasePlugin {
  protected override snakeCase(str: string): string {
    if (snakeLookup[str]) {
      return snakeLookup[str]
    }

    return super.snakeCase(str)
  }

  protected override camelCase(str: string): string {
    if (camelLookup[str]) {
      return camelLookup[str]
    }

    return super.camelCase(str)
  }
}

class MyCamelCasePlugin extends CamelCasePlugin {
  protected override snakeCase(str: string): string {
    if (snakeLookup[str]) {
      return snakeLookup[str]
    }

    return super.snakeCase(str)
  }

  protected override camelCase(str: string): string {
    if (camelLookup[str]) {
      return camelLookup[str]
    }

    return super.camelCase(str)
  }
}

Thanks, very helpful! and I only have information about the column name here? not the table

koskimas•17mo ago

Yeah. Figuring out the table is super hard/impossible

elitanOP•17mo ago

Wouldn't be surprised if I found the same column named in different variations. Like company_id and company_ID for different tables ok hmm Maybe I should first make sure we don't have that issue Thank you @koskimas Keep up the great work with Kysely ❤️

got it working btw 🚀

// convert wierd column names
const snakeLookup = {
  clCompanyID: 'cl_companyID',
} as Record<string, string>;

class CustomCamelCasePlugin extends CamelCasePlugin {
  protected override snakeCase(str: string): string {
    if (snakeLookup[str]) {
      return snakeLookup[str];
    }

    return super.snakeCase(str);
  }
}

// convert wierd column names
const snakeLookup = {
  clCompanyID: 'cl_companyID',
} as Record<string, string>;

class CustomCamelCasePlugin extends CamelCasePlugin {
  protected override snakeCase(str: string): string {
    if (snakeLookup[str]) {
      return snakeLookup[str];
    }

    return super.snakeCase(str);
  }
}

that's it
