mongo adapter $exists - Githubissues

bhaveshbheda commented 6 years ago

Sails version:1.0 Node version:8.10 NPM version:3.5.2 DB adapter name: sails-mongo DB adapter version: 1.0 Operating system: linux after upgrading sails 1.0 from 0.12 in mongo adapter there is no any alternative for "$exists", array notation like "user.$.name" or "user.1" which is working in sails 0.12 and mongo adopter of 0.12 . . . .

Hi @bhaveshbheda! It looks like you missed a step or two when you created your issue. Please edit your comment (use the pencil icon at the top-right corner of the comment box) and fix the following:

Verify "I am experiencing a concrete technical issue (aka a bug) with Sails (ideas and feature proposals should follow the guide for proposing features and enhancements (http://bit.ly/sails-feature-guide), which involves making a pull request). If you're not 100% certain whether it's a bug or not, that's okay--you may continue. The worst that can happen is that the issue will be closed and we'll point you in the right direction."
Verify "I am not asking a question about how to use Sails or about whether or not Sails has a certain feature (please refer to the documentation(http://sailsjs.com), or post on http://stackoverflow.com, our Google Group (http://bit.ly/sails-google-group) or our live chat (https://gitter.im/balderdashy/sails)."
Verify "I have already searched for related issues, and found none open (if you found a related closed issue, please link to it in your post)."
Verify "My issue title is concise, on-topic and polite ("jst.js being removed from layout.ejs on lift" is good; "templates dont work" or "why is sails dumb" are not so good)."
Verify "I have tried all the following (if relevant) and my issue remains:"
Verify "I can provide steps to reproduce this issue that others can follow."

As soon as those items are rectified, post a new comment (e.g. “Ok, fixed!”) below and we'll take a look. Thanks!

streleck commented 6 years ago

@bhaveshbheda Could you use Object.find({key: {'!=': null}})?

OnbitShashan commented 4 years ago

@streleck this does not works. I need the opposite of this. I have something like parentId: { $exists: false } . Now I'm upgrading into sails 1.x and stuck here. I need to fetch all the records that does not contain parentId .

johnabrams7 commented 4 years ago

@OnbitShashan we just released sails-mongo 1.1.0 yesterday - can you try this query in the new version of the adapter? This update expands overall functionality, compatibility, and official support for mongo 3.6 (thorough testing / official support for mongo 4.x still being developed but should be relatively compatible).

OnbitShashan commented 4 years ago

@johnabrams7 I have tried this with 1.1.0. Still did not work. Find the error log below,

Error => UsageError: Invalid criteria. Refer to the docs for up-to-date info on query language syntax:

Please note that I tried with "$exists" and "exists"

johnabrams7 commented 4 years ago

@OnbitShashan Ah! In Sails 1.0/Waterline 0.13, we actually have stricter built-in validations, which is why this doesn’t work anymore. See .manager and .native() queries.

OnbitShashan commented 4 years ago

@johnabrams7 yeah writing code in native works. Sorry for the late reply
