goctl model

Overview

The database model code generation instruction provided by goctl model for goctl is currently supported by MySQL, PostgreSQL, Mongo code generation, MySQL support from sql files and database connections and PostgreSQL support from database connections only.

goctl model directive

$ goctl model  --help
Generate model code

Usage:
  goctl model [command]

Available Commands:
  mongo       Generate mongo model
  mysql       Generate mysql model
  pg          Generate postgresql model

Flags:
  -h, --help   help for model


Use "goctl model [command] --help" for more information about a command.

goctl model mono directive

Mongo is generated different than MySQL. MySQL and MySQL can read a table of information (field name, data type, index, etc.) from the scheme_information library, while Mongo is a document type database, we are temporarily unable to read a record from the db to get the field information, even if it is not necessarily complete (some fields may be omitempty modifications, if any) where type type is self-writing+ code generated.

$ goctl model mongo --help
Generate mongo model

Usage:
  goctl model mongo [flags]

Flags:
      --branch string   The branch of the remote repo, it does work with --remote
  -c, --cache           Generate code with cache [optional]
  -d, --dir string      The target dir
  -e, --easy            Generate code with auto generated CollectionName for easy declare [optional]
  -h, --help            help for mongo
      --home string     The goctl home path of the template, --home and --remote cannot be set at the same time, if they are, --remote has higher priority
      --remote string   The remote git repo of the template, --home and --remote cannot be set at the same time, if they are, --remote has higher priority
                        The git repo directory must be consistent with the https://github.com/zeromicro/go-zero-template directory structure
      --style string    The file naming format, see [https://github.com/zeromicro/go-zero/tree/master/tools/goctl/config/readme.md]
  -t, --type strings    Specified model type name

Parameter field	Parameter Type	Required?	Default value	Parameter Description
branch	string	NO	Empty string	Remote template name is used only if remote has value
cache	boolean	NO	false	Whether or not to generate code with cache
dir	string	NO	Current working directory	Generate Code Output Directory
easy	boolean	NO	false	Exposure pool name variable
home	string	NO	${HOME}/.goctl	Local Template File Directory
remote	string	NO	Empty string	Remote template is a git repository address. Priority is higher than home field value when this field is passed
style	string	NO	gozero	Named style symbols for output files and directories, see file style
type	[]string	YES	nil	Structure Type Name

Examples

Below are examples of generating a user structure.

1 Whether or not to generate code with cache

# enter user home
$ cd ~

# make dir named demo 
$ mkdir demo && cd demo

# generate mongo code by goctl
$ goctl model mongo --type User --dir cache --cache

type mapping customization

Type mapping customization can only be used in the experimental version. For how to enable the experimental version, please refer to goctl env，For configuration use, please refer to goctl config

Example 1. Modify decimal to decimal. Decimal type

1. Initialize configuration in projects that need to generate models

$ goctl config init
goctl.yaml generated in ~/workspace/go-zero/tools/goctl/goctl.yaml

2. Modify the type mapping relationship

The grey shading is a custom mapping type.

model:
  types_map:
    bigint:
      null_type: sql.NullInt64

Add type mappings not supported by goctl built-in

We have a pg in the table with data type inet.

-- auto-generated definition
create table student
(
    id          integer                               not null
        constraint student_pk
            primary key,
    name        varchar default ''::character varying not null,
    age         integer default 0                     not null,
    description integer                               not null,
    ip_address  inet    default '0.0.0.0'::inet       not null
);

alter table student
    owner to postgres;

Currently goctl built-in type mappings do not support types, so goctl will report an error as follows:

$ goctl model pg datasource --url="postgres://postgres:postgrespw@127.0.0.1:55000/postgres?sslmode=disable" --table="user,student" --dir . 
Error: unsupported database type: inet

To solve the above problem, in the past, the goctl version was not supported. You could only add rules to the built-in type mapping rules, and then send the version, but now you only need to add a type mapping rule in the configuration file.

Provided that the goctl version is greater than or equal to 1.6.5, and the experimental function is started

1. Check if the goctl version meets the conditions

$ goctl env
GOCTL_OS=darwin
GOCTL_ARCH=arm64
GOCTL_HOME=/Users/sh00414ml/.goctl
GOCTL_DEBUG=False
GOCTL_CACHE=/Users/sh00414ml/.goctl/cache
GOCTL_EXPERIMENTAL=on # If the experimental function tube is off, it needs to be turned on. The opening command is goctl env -w GOCTL_EXPERIMENTAL = on
GOCTL_VERSION=1.6.5 # goctl version
PROTOC_VERSION=3.19.4
PROTOC_GEN_GO_VERSION=v1.28.0
PROTO_GEN_GO_GRPC_VERSION=1.2.0

2. Initialize goctl configuration in the target project

$ goctl config
goctl.yaml generated in ~/demo/goctl-config/goctl.yaml # This is based on the output of your own computer, which is for reference only.

3. Modify goctl.yaml

To increase the target data type and mapping relationship, add an inet mapping here. The example is as follows: Grey shading

model:
  types_map:
    bigint:
      null_type: sql.NullInt64
      type: int64
      unsigned_type: uint64
    ...
    inet:
      null_type: sql.NullString
      type: string

4. Generate model code again

goctl model pg datasource --url="postgres://postgres:postgrespw@127.0.0.1:55000/postgres?sslmode=disable" --table="user,student" --dir . 
Done.
