如何使用sequelize执行原始PostGIS查询使用包括

Question

尝试使用内置ORM便利性的sequelize包括具有原始PostGIS查询的语法。

此调用正确联接相关promotionImage和类别表只是因为我需要它，但它并不地理查询我的数据库就像我需要它：正确

promotion.findAll({ 
    include: [{ 
     model: promotionImage 
    }, { 
     model: category 
    }] 
    }).then(promoters => { 
    res.json(promoters) 
    }).catch(err => { 
    console.log('ERROR: ', err) 
    }) 

在另一方面，这种查询发现所提供的纬度/经度范围内的“促销活动”，但它不能正常参加相关promotionImage和类别表：

const query = '\ 
     SELECT * \ 
     FROM "promotions" \ 
     WHERE "promotions"."location" && ST_MakeEnvelope(:southWestLng, :southWestLat, :northEastLng, :northEastLat)' 
    replacements = { 
     southWestLng, 
     southWestLat, 
     northEastLng, 
     northEastLat 
    } 

    db.sequelize.query(query, { 
    replacements, 
    type: sequelize.QueryTypes.SELECT, 
    model: promotion, 
    include: [{ 
     model: promotionImage 
    }, { 
     model: category 
    }] 
    }).then(promoters => { 
    res.json(promoters) 
    }).catch(err => { 
    console.log('ERROR: ', err) 
    }) 

有没有办法既查询使用ST_MakeEnvelope语法和包括从数据其他型号sequelize和postGIS？

Sequelize.query()不支持include，您可以使用Sequelize.fn()与findAll

promotion.findAll({ 
    where: { 
     location: { 
      $overlap: db.sequelize.fn('ST_MakeEnvelope', southWestLng, southWestLat, northEastLng, northEastLat) 
     } 
    }, 
    include: [{ 
     model: promotionImage 
    }, { 
     model: category 
    }] 
    }).then(promoters => { 
    res.json(promoters) 
    }).catch(err => { 
    console.log('ERROR: ', err) 
    })
