Foreign key is being capitalised in query resulting in "SequelizeDatabaseError: column Book.UserId does not exist"

What you are doing?

I am trying to perform a simple join;

models.User.find({
      where: {
        emailAddress: request.payload.emailAddress
      },
      include: [{
        model: models.Book,
      }]
    })

What is actually happening?

and I get the error ‘“SequelizeDatabaseError: column Book.UserId does not exist”’

The field is called ‘userId’. How can I fix this?

Dialect: postgres __Database version: 9.4 __Sequelize version: 3.20.0

(Didn’t you post your complete models before 😉?)

The foreign key name will match the name of the model - so if the user has User as the name, the foreign key will be UserId. For example if you defined

User.hasOne(models.Book, { foreignKey: 'userId' });
Book.belongsTo(User)

Sequelize will get confused and add both userId and UserId - You have to add the foreign key to both associations.

Without seeing your complete model definitions and associations so I can replicate the issue, its hard to say whats at play here 😉

@fiftin You should explicitly specify the foreign key on both ends:

User.hasOne(models.Book, { foreignKey: 'userId' });
Book.belongsTo(User, { foreignKey: 'userId' });

Or not specify it at all.

Are you looking for a different solution? I don’t think that exists.
