NAME:
    cwgo model-generate DB model

                 Examples:
                   # Generate DB model code
                   cwgo model --db_type mysql --dsn "gorm:gorm@tcp(localhost:9910)/gorm?charset=utf8&parseTime=True&loc=Local"


USAGE:
    cwgo model [command options] [arguments...]

OPTIONS:
    --dsn value Specify the database source name. (https://gorm.io/docs/connecting_to_the_database.html)
    --db_type value Specify database type. (mysql or sqlserver or sqlite or postgres) (default: mysql)
    --out_dir value Specify output directory (default: biz/dao/query)
    --out_file value Specify output filename (default: gen.go)
    --tables value [ --tables value ] Specify databases tables
    --exclude_tables value [ --exclude_tables value ]  Specify exclude tables
    --unittest Specify generate unit test (default: false)
    --only_model Specify only generate model code (default: false)
    --model_pkg value Specify model package name
    --nullable Specify generate with pointer when field is nullable (default: false)
    --signable Specify detect integer field\'s unsigned type, adjust generated data type (default: false)
    --type_tag Specify generate field with gorm column type tag (default: false)
    --index_tag Specify generate field with gorm index tag (default: false)
    --help, -h show help (default: false)
