Provides Json-Schema based database rows to arbitrary struct scanner generation

generows

Json-schema based database rows to arbitrary struct scanner generation with Go (golang). It is based on database/sql so it works with all database drivers

Why Code Generation?

Whenever a bootstrap is required for a project we are hustling with creating the required folder, files, databases, roles/users schemas, sequences, tables, constraints, extensions types etc...

This package aims to ease that pain

What is JSON-Schema?

JSON Schema specifies a JSON-based format to define the structure of your data for various cases, like validation, documentation, and interaction control. A JSON Schema provides a contract for the JSON data required by a given application, and how that data can be modified.

TLDR: here is an example twitter.json

Where is sample output?

Right here twitter/models/account_rowscanner

package models

import "database/sql"

func (a *Account) RowsScan(rows *sql.Rows, dest interface{}) error {
    if rows == nil {
        return nil
    }

    var records []*Account
    for rows.Next() {
        m := NewAccount()
        err := rows.Scan(
            &m.ID,
            &m.ProfileID,
            &m.Password,
            &m.URL,
            &m.PasswordStatusConstant,
            &m.Salt,
            &m.EmailAddress,
            &m.EmailStatusConstant,
            &m.StatusConstant,
            &m.CreatedAt,
        )
        if err != nil {
            return err
        }
        records = append(records, m)
    }

    if err := rows.Err(); err != nil {
        return err
    }

    *(dest.(*[]*Account)) = records

    return nil
}
