This database package is part of the GoCryptoTrader codebase.
|
|
|
|
## This is still in active development
|
|
|
|
You can track ideas, planned features and what's in progress on our [GoCryptoTrader Kanban board](https://github.com/orgs/thrasher-corp/projects/3).

## Current Features for database package
|
|
|
|
+ Establishes & Maintains database connection across program life cycle
|
|
+ Migration handed by [Goose](https://github.com/thrasher-corp/goose)
|
|
+ Model generation handled by [SQLBoiler](https://github.com/thrasher-corp/sqlboiler)
|
|
|
|
## How to use
|
|
|
|
##### Prerequisites
|
|
|
|
[SQLBoiler](https://github.com/thrasher-corp/sqlboiler)
|
|
```shell script
|
|
go install github.com/thrasher-corp/sqlboiler
|
|
```
|
|
|
|
[Postgres Driver](https://github.com/thrasher-corp/sqlboiler/drivers/sqlboiler-psql)
|
|
```shell script
|
|
go install github.com/thrasher-corp/sqlboiler/drivers/sqlboiler-psql
|
|
```
|
|
|
|
[SQLite Driver](https://github.com/thrasher-corp/sqlboiler-sqlite3)
|
|
```shell script
|
|
go install github.com/thrasher-corp/sqlboiler-sqlite3
|
|
```
|
|
|
|
##### Configuration
|
|
|
|
The database configuration struct is currently:
|
|
```shell script
|
|
type Config struct {
|
|
Enabled bool `json:"enabled"`
|
|
Verbose bool `json:"verbose"`
|
|
Driver string `json:"driver"`
|
|
drivers.ConnectionDetails `json:"connectionDetails"`
|
|
}
|
|
```
|
|
And Connection Details:
|
|
```sh
|
|
type ConnectionDetails struct {
|
|
Host string `json:"host"`
|
|
Port uint16 `json:"port"`
|
|
Username string `json:"username"`
|
|
Password string `json:"password"`
|
|
Database string `json:"database"`
|
|
SSLMode string `json:"sslmode"`
|
|
}
|
|
```
|
|
|
|
With an example configuration being:
|
|
|
|
```sh
|
|
"database": {
|
|
"enabled": true,
|
|
"verbose": true,
|
|
"driver": "postgres",
|
|
"connectionDetails": {
|
|
"host": "localhost",
|
|
"port": 5432,
|
|
"username": "gct-dev",
|
|
"password": "gct-dev",
|
|
"database": "gct-dev",
|
|
"sslmode": "disable"
|
|
}
|
|
},
|
|
```
|
|
|
|
##### Create and Run migrations
|
|
Migrations are created using a modified version of [Goose](https://github.com/thrasher-corp/goose)
|
|
|
|
A helper tool sits in the ./cmd/dbmigrate folder that includes the following features:
|
|
|
|
+ Check current database version with the "status" command
|
|
```shell script
|
|
dbmigrate -command status
|
|
```
|
|
|
|
+ Create a new migration
|
|
```sh
|
|
dbmigrate -command "create" -args "model"
|
|
```
|
|
_This will create a folder in the ./database/migration folder that contains postgres.sql and sqlite.sql files_
|
|
+ Run dbmigrate command with -command up
|
|
```shell script
|
|
dbmigrate -command "up"
|
|
```
|
|
|
|
dbmigrate provides a -migrationdir flag override to tell it what path to look in for migrations
|
|
|
|
###### Note: its highly recommended to backup any data before running migrations against a production database especially if you are running SQLite due to alter table limitations
|
|
|
|
|
|
##### Adding a new model
|
|
Model's are generated using [SQLBoiler](https://github.com/thrasher-corp/sqlboiler)
|
|
A helper tool has been made located in gen_sqlboiler_config that will parse your GoCryptoTrader config and output a SQLBoiler config
|
|
|
|
```sh
|
|
gen_sqlboiler_config
|
|
```
|
|
|
|
By default this will look in your gocryptotrader data folder and default config, these can be overwritten
|
|
along with the location of the sqlboiler generated config
|
|
|
|
```shell script
|
|
-config "configname.json"
|
|
-datadir "~/.gocryptotrader/"
|
|
-outdir "~/.gocryptotrader/"
|
|
```
|
|
|
|
Generate a new model that gets placed in ./database/models/<databasetype> folder
|
|
|
|
Linux:
|
|
```shell script
|
|
sqlboiler -o database/models/postgres -p postgres --no-auto-timestamps --wipe psql
|
|
```
|
|
Windows:
|
|
```sh
|
|
sqlboiler -o database\\models\\postgres -p postgres --no-auto-timestamps --wipe psql
|
|
```
|
|
|
|
Helpers have been provided in the Makefile for linux users
|
|
```
|
|
make gen_db_models
|
|
```
|
|
And in the contrib/sqlboiler.cmd for windows users
|
|
|
|
##### Adding a Repository
|
|
+ Create Repository directory in github.com/thrasher-corp/gocryptotrader/database/repository/
|
|
|
|
|
|
##### DBSeed helper
|
|
A helper tool [cmd/dbseed](../cmd/dbseed/README.md) has been created for assisting with data migration
