How to perform date comparisons against postgres with sequelize
I want to delete all records with dates before 20 minutes ago. Postgres (or Sequelize) is not satisfied with the bare javascript Date object I provide as the comparison value.
I'm using sequelize 4.37 on top of a postgres 9.6 database.
The column in question was declared with type: Sequelize.DATE, which research suggests is equivalent to TIMESTAMP WITH TIME ZONE: a full date and time with microsecond precision and a timezone signifier. (That is also what I see when I use the psql CLI tool to describe the table.)
So, I do this:
const Sequelize = require('sequelize')
const { SomeModel } = require('../models.js')
// calculate 20 minutes ago
async function deleteStuff() {
const deletionCutoff = new Date()
deletionCutoff.setMinutes( deletionCutoff.getMinutes() - 20 )
await SomeModel.destroy({
where: {
[ Sequelize.Op.lt ]: { dateColumn: deletionCutoff }
}
})
But I get this error:
Error: Invalid value { dateColumn: 2018-11-21T21:26:16.849Z }
The docs suggest I should be able to provide either a bare javascript Date, or an ISO8601 string, but both throw the same Invalid Value error. The only difference is that, if I pass a string, the error shows single quotes around the value:
// error when dateColumn: deletionCutoff.toISOString()
Error: Invalid value { dateColumn: '2018-11-21T21:26:16.849Z' }

Well, this is pretty embarrassing. I structured the where clause incorrectly.
// BAD CODE
await SomeModel.destroy({
where: {
[ Sequelize.Op.lt ]: {
dateColumn: deletionCutoff
}
}
})
// GOOD CODE
await SomeModel.destroy({
where: {
dateColumn: {
[ Sequelize.Op.lt ]: deletionCutoff
}
}
})
Maybe I should delete the question. Maybe not -- the error I got probably could be more helpful.
