Knex: UUID and MD5 generated

What is the reason why

But the 'knex.raw('uuid_generate_v4()')'

Doesn't work? Does that work with postgrsql when you try to use it with plain sql wirhout knex?

Try also running your code with DEBUG=knex:* evironment variable set to get more info whats going on with your queries.

@anzileiro, you should not use uuis-v4 package in migrations, but in your models, for example before saving a new model, set its property hash to the value of uuid() and then save it

You need to make sure the extension is available:

knex.raw('create extension if not exists "uuid-ossp"')

then you can do

table.string('hash').defaultTo(knex.raw('uuid_generate_v4()'))

don't forget down migration:

knex.raw('drop extension if exists "uuid-ossp"')

Edit: You can use uuid type instead of string when using pg, e.g:

await knex.schema.createTable('Users', t => {
  t.uuid('id').defaultTo(knex.raw('uuid_generate_v4()'))
  // ...
})

Thanks @fl0w, case closed ☺️
