How to order by included table's JSONB field

[sennmac]

hi dear devs

I have some tables a like
budget
{id:''}
budgetDetail
{id:'',budgetIdl:'',detail:{amount:1}}

I need to search on the budget table and include the budgetDetail table then order by the detail->amount.

so I write code like
Budget.findAll({include:[budgetDetail],order:[Models.budgetDetail,Models.sequelize.literal("detail->>'amount'")]})

but you know the amount is a text in jsonb, so I need to convert it into a number.

Budget.findAll({include:[budgetDetail],order:[Models.budgetDetail, Models.sequelize.fn('TO_NUMBER', Models.sequelize.literal("budgetDetail".detail->>'amount'"),]})

But the raw SQL will render into

ORDER BY "budgetDetail".TO_NUMBER("detail->>'amount'") ASC

which will fail.

You don't need to specify the model if you use a literal or fn:

Budget.findAll({
  include: [BudgetDetail],
  order: [fn('TO_NUMBER', literal(`"budgetDetail".detail->>'amount'"`)],
});

Thanks for your reply.
I just find out that I used the wrong operator.
I should use this one ->, -> will return the right type.
And for ->> will always return text in jsonb.

Again, thank you.~
