I try to figure out how to create a tables (user, role and permissions) with relationships and make the an example how to use them. ``` const users = pgTable("users", { id: serial("id").primaryKey(), name: text("name").notNull(), email: text("email").notNull(), password: text("password").notNull(), }); const roles = pgTable("roles", { id: serial("id").primaryKey(), name: text("name").notNull(), }); const permissions = pgTable("permissions", { id: serial("id").primaryKey(), name: text("name").notNull(), }); const usersRelations = relations(users, ({ one, many }) => ({ role: one(roles, { fields: [users.id], references: [roles.userId], }), permissions: many(permissions, (join) => join.through(userRoles)), })); ```
