FindOne() does not honor multiple where() #6830

Open grd2345 opened 5 years ago

grd2345 commented 5 years ago

Node version: v8.16.0 Sails version (sails): 1.2.3 ORM hook version (sails-hook-orm): 2.1.1 Sockets hook version (sails-hook-sockets): 1.5.5 Grunt hook version (sails-hook-grunt): 1.0.8 DB adapter & version (e.g. sails-mysql@5.55.5): 1.0.2


I am in the process of migrating to version 1 and their is a breaking change that I did not see on the migration documents. This used to work in the prior version.

Agreement.findOne() .where({id: agreementId}) .where({locationId: employee.currentLocation.id})

Now this fails with

More than one matching record found for .findOne():

I stepped through the adapter code and it ignores all .where() except the last where, which is an issue.

Just a note, this issue is occuring also using Find() with multiple where(). It does not honor multiple where anymore.Is this by design or a bug.

Hi @grd2345 honestly the word findOne means find only one document in the DB, with a specific attribute that matches only one record [eg -> id], if multiple records was matched sails would panic, which means that duplicates records was entered twice somehow, this is not actually related to FindOne() honoring multiple where() clause. rewriting your code with one .where({ id: agreementId, locationId: employee.currentLocation.id }) will still throw this error, this is a common problem i've faced with sails in the past, but a work around is dope!

@grd2345 Thanks for bringing this to attention! @navicstein Thanks for the response as well! find() is indeed recommended for multiple results - while findOne() is designed for a single result. As for defining multiple criteria with where() (combined with find()), these are specified within a single where() clause.

Sails console example: Agreement.find()({where: {id: agreementId, locationId: employee.currentLocation.id}}).log()

thanks, yes, I refactored to not use chain-able where clauses anymore. just wanted to inform that version prior to v1 allowed chainable where clauses and not anymore.

Thanks for everything.

@grd2345 Ah, yes Sails 1.x has breaking changes for how waterline handles where(). Glad it worked out!
