Question

我有exports file包含所有续集模型，然后定义模型之间的关系。它看起来像：

// Snippet from the global init file

for (let modelFile of modelFileList) {
            // ... Some code ...

            // Require the file
            appliedModels[modelName] = require(`../${MODEL_DIR}/${modelFile}`).call(null, _mysql);
 }

 //Define the relationship between the sql models
 _defineRelationship(appliedModels);


function _defineRelationship(models) {
     models._planAllocationModel.belongsTo(models._subscriptionModel, {
            foreignKey: 'subscription_id',
            targetKey: 'subscription_id'
        });
}

但是当我尝试将模型包括在内时：

 _subscriptionModel.findAll({
                where: {
                    start_date: {
                        _lte: today // Get all subscriptions where start_date <= today
                    }
                },
                limit,
                include: [
                    {
                        model: _planAllocationModel
                    }
                ]
            });

sequelize引发了一个错误：SequelizeEagerLoadingError: tbl_plan_allocation is not associated to tbl_subscription_info!这可能是什么原因？我已经初步确定了两个模型之间的关系。

Answer 1

我能够解决问题。该关系定义为belongsTo，由于hasOne查询中应用的join类型，该关系必须更改为findAll。

SequelizeEagerLoadingError已定义模型之间的关系
