Django style fixtures for Golang's excellent built-in database/sql library. Currently only YAML fixtures are supported.

---

There are two reserved values you can use for datetime fields:

• ON_INSERT_NOW() will only be used when a row is being inserted
• ON_UPDATE_NOW() will only be used when a row is being updated

Example YAML fixture:

---

- table: 'some_table'
  pk:
    id: 1
  fields:
    string_field: 'foobar'
    boolean_field: true
    created_at: 'ON_INSERT_NOW()'
    updated_at: 'ON_UPDATE_NOW()'

- table: 'other_table'
  pk:
    id: 2
  fields:
    int_field: 123
    boolean_field: false
    created_at: 'ON_INSERT_NOW()'
    updated_at: 'ON_UPDATE_NOW()'

- table: 'join_table'
  pk:
    some_id: 1
    other_id: 2

Example integration for your project:

package main

import (
    "database/sql"
    "io/ioutil"
    "log"

    "github.com/RichardKnop/go-fixtures"
    "github.com/urfave/cli"
    // Drivers
    _ "github.com/lib/pq"
)

var (
    cliApp *cli.App
)

func init() {
    cliApp = cli.NewApp()
    cliApp.Name = "your-project"
    cliApp.Usage = "Project's usage"
    cliApp.Author = "Your Name"
    cliApp.Email = "your@email"
    cliApp.Version = "0.0.0"
}

func main() {
    db, err := sql.Connect("postgres", "user=foo dbname=bar sslmode=disable")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    cliApp.Commands = []cli.Command{
        {
            Name:  "loaddata",
            Usage: "load data from fixture",
            Action: func(c *cli.Context) error {
                data, err := ioutil.ReadFile(c.Args().First())
                if err != nil {
                    return err
                }

                if err := fixtures.Load(data, db, "postgres"); err != nil {
                    return err
                }
            },
        },
        {
            Name:  "runserver",
            Usage: "run web server",
            Action: func(c *cli.Context) error {
                // Run your web server here
                return nil
            },
        },
    }

    cliApp.Run(os.Args)
}
