我用sequelize-auto提取了一些PostGis图层的模型,给出:
module.exports = function(sequelize, DataTypes) {
return sequelize.define('table', {
id: {
type: DataTypes.INTEGER,
allowNull: false,
primaryKey: true,
autoIncrement: true
},
geom: {
type: DataTypes.GEOMETRY('POINT', 4326),
allowNull: true,
},
...

在GET上,sequelize将geom作为GeoJSON发送给客户端:
{
"type":"Point",
"coordinates":[11.92164103734465,57.67219297300486]
}

当我尝试将此Posgis错误保存为:
ERROR: Geometry SRID (0) does not match column SRID (4326)

这个答案给出了如何添加SRID的神的指示(如何在Sequelize ORM中插入PostGIS几何点?),
var point = {
type: 'Point',
coordinates: [39.807222,-76.984722],
crs: { type: 'name', properties: { name: 'EPSG:4326'} }
};
User.create({username: 'username', geometry: point }).then(function(newUser) {
...
});

我知道SRID曾经是从sequelize中删除的功能(https://github.com/sequelize/sequelize/issues/4054).
有没有人知道一种方法来挂钩Sequelize,以便将srid添加到发送给PostGis的GeoJson?在哪里放?在模型的设定者?
