Sails.js 如何从sailsjs中的现有数据库生成模型？

我从

SailsJS

和

MySQL

开始，我的数据库中有很多表。所以，我不知道在

SailsJS

中有一个从数据库生成模型的工具，比如

database First

在

实体框架中（
ASP
）
SailsJS没有实现这样的工具

尽管如此，您自己创建它应该不难，因为MySQL的
SHOW COLUMNS FROM table
工作得非常好。然后您只需创建.js模型文件

请注意
config/models.js
中的配置，并将migrate设置为safe，因为如果您没有测试并且不确定是否正确生成了模型，您可能会删除一些列。
您应该使用，自动生成现有的模型库数据库非常好。

看一看

Sails反向模型帮助您从任何数据库构建模型、控制器和视图JS Sails。此外，您可以快速、单独地同时生成每个模型、视图、控制器或所有三个

使用命令安装

npm安装帆逆模型-g

  Example:
$ mkdir sails-output
$ cd sails-output
$ sails-inverse-model -u postgres -p root -d almacen -t pg -m -v -c

User         : postgres
Password     : root
Database     : almacen
Host         : localhost
Models       : /home/julian/Documents/sails-output/models
Views        : /home/julian/Documents/sails-output/views
Controllers  : /home/julian/Documents/sails-output/controllers
DB           : pg
Schema (pg)  : public
=====================================
Views [OK]
=====================================
Models [OK]
=====================================
Controllers [OK]

  Note: Copy models      => your/project_sails/api
        Copy controllers => your/project_sails/api
        Copy views/*     => your/project_sails/views/

Then: 


$ cd your/project_sails/
$ sails lift

====================== Individual generation ==================
  You can quickly generate a model, a controller, a view or these three at the same time.
  # Generate model 
  $ sails-inverse-model -g model --name Pet -a "name:string:r:u owner:string"

  # Generate Controller 
  $ sails-inverse-model -g controller --name Pet -a "name:string:r:u owner:string"

  # Generate View 
  $ sails-inverse-model -g view --name Pet -a "name:string:r owner:string"

  # Generate all (Model, View and Controller) 
  $ sails-inverse-model -g all --name Pet -a "name:string:r:k owner:string"

  Where:
  --------------------------------------------
  |Param | Description   |     Example       |
  |------|---------------|-------------------|
  |   r  | Required      | catname:string:r  |
  |   u  | Unique        | catname:string:u  |
  |   a  | Autoincrement | index:integer:a   |
  |   k  | Primary Key   | index:integer:k   |
  --------------------------------------------
  You can also set all three parameters at the same time, for example: index:integer:a:u:r
