Seed with relation in knex - postgresql

Question

Hi guys I'm trying to seed my data with knex and knex cli
I have 2 models: User & User Profile
User
CREATE TABLE users(
id SERIAL PRIMARY KEY NOT NULL,
name TEXT,
screenname TEXT,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
)
User Profile
CREATE TABLE userProfile(
email TEXT,
password TEXT,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
user_id INTEGER,
PRIMARY KEY (user_id),
FOREIGN KEY (user_id) REFERENCES users (id)
)
Note that user Profile points to User and its 1:1 relationship
Os I'm trying to insert my users and along with that, to insert their profile data
I have created seed file like this:
exports.seed = function(knex) {
// Deletes ALL existing entries
return knex('users').del()
.then(function () {
return knex('userprofile').del();
})
.then(() => {
return knex('authenticationproviders').del();
})
.then(function () {
return knex('users')
.insert([
{
name: 'john',
screenname: 'admin'
},
{
name: 'stephan',
screenname: 'maras'
},
])
})
.then(function (users) {
// here insert profile info about user
// but user param doesn't contain userIds that are created
})
};
Here is how my profiles array looks:
[{
email: 'test#gmail.com',
user_id: 1, // this should be from existing user
password: 'pass1'
},
{
email: 'test2#gmail.com',
user_id: 2, // this should be from existing user that was created
password: 'pass2'
}]
Is there anyway how can I get userId from existing user, since users param is does not contain array of created users ??
