'use strict';
module.exports = (sequelize, type) => {
const article_comments_user_ratings = sequelize.define('article_comments_user_ratings', {
id: {
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: type.INTEGER
},
rating:{
type: type.BOOLEAN,
allowNull: false
},
createdAt: {
allowNull: false,
type: type.DATE
},
updatedAt: {
allowNull: false,
type: type.DATE
}
}, {});
article_comments_user_ratings.associate = function(models) {
// associations can be defined here
article_comments_user_ratings.belongsTo(models.article_comments)
};
return article_comments_user_ratings;
};
但是,当我使用findOrCreate方法时,它只会执行INSERT INTO "article_comments_user_ratings" ("id","rating","createdAt","updatedAt").
,这显然是失败的,因为在数据库中,我还为article_comments_user_ratings表添加了user_id和comment_id列。
这没有任何意义,因为有了sync()函数,在进行迁移之前它就可以正常工作。
我不知道该怎么办?
答案 0 :(得分:0)
我通过在定义模型后定义关联来解决此问题。
示例:
const User = UserModel(sequelize, Sequelize)
const Comment = CommentsModel(sequelize, Sequelize)
User.hasMany(UserCommentRating,{foreignKey:'user_id'})
Comment.hasMany(UserCommentRating,{foreignKey:'comment_id'})
似乎不推荐使用模型内部的关联。
