Javascript Sequelize多对多关系表获得不需要的额外列

我试图在模型

调查

和

问题

之间定义一个m:N关系。关系的名称为

SurveyHasQuestions

，它也有一个定义（请进一步了解它在关联定义中的用法）：

数据库中正确生成了

调查

和

问题

的表格（顺便说一句，该表格是Postgres）：

及

现在，以下协会：

Survey.hasMany(SurveyQuestion, {through: SurveyHasQuestions, foreignKey: 'survey_id'});
SurveyQuestion.hasMany(Survey, {through: SurveyHasQuestions, foreignKey: 'question_id'});
SurveyHasQuestions.belongsTo(Survey, {foreignKey: 'survey_id'});
SurveyHasQuestions.belongsTo(SurveyQuestion, {foreignKey: 'question_id'});

SurveyQuestion.belongsToMany(Survey, {
    through: SurveyHasQuestions,
    foreignKey: 'question_id'
});
Survey.belongsToMany(SurveyQuestion, {
    through: SurveyHasQuestions,
    foreignKey: 'survey_id'
});

正确工作，即他们为M:N与所需结构的关系生成一个

survey\u has\u questions

表：

shq_id: integer (pkey)
question_id: integer (fkey references survey_question.question_id)
survey_id: integer (fkey references survey.survey_id)

但sequelize发出了警告：

使用2xhasmany表示N:M关系已被弃用。请改用belongtomany

因此，为了正确地执行操作，我尝试只使用

belongtomany（）

。但这些协会：

Survey.hasMany(SurveyQuestion, {through: SurveyHasQuestions, foreignKey: 'survey_id'});
SurveyQuestion.hasMany(Survey, {through: SurveyHasQuestions, foreignKey: 'question_id'});
SurveyHasQuestions.belongsTo(Survey, {foreignKey: 'survey_id'});
SurveyHasQuestions.belongsTo(SurveyQuestion, {foreignKey: 'question_id'});

SurveyQuestion.belongsToMany(Survey, {
    through: SurveyHasQuestions,
    foreignKey: 'question_id'
});
Survey.belongsToMany(SurveyQuestion, {
    through: SurveyHasQuestions,
    foreignKey: 'survey_id'
});

为

调查生成\u有\u问题

不正确的表格：

shq_id: integer (pkey)
question_id: integer (fkey references survey_question.question_id)
survey_survey_id: integer (fkey references survey.survey_id) <---??? UNWANTED
survey_id: integer (fkey references survey.survey_id)

shq_id:integer（pkey） 问题id：整数（fkey参考调查问题。问题id） survey_survey_id:integer（fkey references survey.survey_id）这是一个bug：

此后，它已在最新版本中修复，该版本位于v2.0.3：

在此处获取v2.0.3：

shq_id: integer (pkey)
question_id: integer (fkey references survey_question.question_id)
survey_survey_id: integer (fkey references survey.survey_id) <---??? UNWANTED
survey_id: integer (fkey references survey.survey_id)
