How to get the current model name or use other method at runtime in Prisma ORM - orm

Question

New feature has been included In prisma ORM version 4.9.0 Doc Link
After update schema.prisma as follow
generator client {
provider = "prisma-client-js"
previewFeatures = ["clientExtensions"]
}
How do we get model name at runtime and use other method also at runtime
const { PrismaClient, Prisma } = require("#prisma/client");
const db = new PrismaClient().$extends({
client: {
log: (s) => console.log(s),
async useLog() {
// how to use log function
// here
},
},
model: {
$allModels: {
log: (s) => console.log(s),
async find(id, option = {}) {
// how to get current model name in runtime
// or use other function here
},
},
},
});
module.exports = { db };

Here is the solution
const { PrismaClient, Prisma } = require("#prisma/client");
const db = new PrismaClient().$extends({
client: {
log: (s) => console.log(s),
async useLog() {
const ctx = Prisma.getExtensionContext(this);
ctx.log("test"); // it will print "test" on console
},
},
model: {
$allModels: {
log: (s) => console.log(s),
async find(id, option = {}) {
const ctx = Prisma.getExtensionContext(this);
// here is log the current runtime model name
console.log(ctx.name);
// here we can use other method of prisma model
return ctx.findUniqueOrThrow({
where: {
id,
},
...option,
});
},
},
},
});
module.exports = { db };
Now we can use find method in all model just like
const { db } = require("#app/src/utils/db");
const teacher = await db.teacher.find(teacherId);
const student = await db.student.find(studentId);
