QUESTION
Using Ruby 3.1.1.
Trying to implement similar to: https://github.com/mongodb/mongoid/blob/master/lib/mongoid/fields.rb :: class_attribute :fields
When I include a model concern on a parent model the class_attributes seem to get merged on child models. I wanted to maintain a seperate class_attribute hash on each child class, like the mongoid Field concern does.
This only seems to occur when inheriting.
...ANSWER
Answered 2022-Apr-10 at 23:03I took a lot of edits and some digging to figure out the question and whats going on. Sorry.
Whats happening is that with class_attribute is that all the classes are actually sharing the same object in thier instance attributes. This is an intended behavior.
You can actually get it to work with class_attribute if you make sure that each subclass gets a duplicate of the "parent hash":

I've two async functions, which are async function start(){} & async function end(){}
So in both functions I'm having mongodb operations. I want to send document id generated inside start() function to the end() function and then log it there.
This is my start function:
ANSWER
Answered 2022-Mar-24 at 19:05The best way, since you want to access the value some time later, would be to save it to a database or some file. As for the order of calling the function to receive the original id just call the end() function without calling the start().

I'm trying to upgrade Mongoid in an Rails 4.2 app from 4.x to 5.x (5.4.1) to connect to a MongoDB 2.6.
I've updated the mongoid.yml file to match the differences of 5.x:
ANSWER
Answered 2022-Jan-20 at 06:21MongoDB documentation is a bit confusing here.
The link you posted is referring the the compatibility between mongoid and the ruby mongodb driver.
There is another page with a matrix representing the compatibility of the ruby driver and the mongoDB server.
QUESTION
We have a collection of documents, each document has an array of objects
...ANSWER
Answered 2022-Jan-14 at 15:06In general, it is wise to separate DB-specific resources from business/data domain resources. You always want to be able to manipulate the data completely independent of the host database and the drivers associated therewith. ObjectId() is relatively lightweight and in fact a BSON type, separate from the MongoDB core objects, but for true arms-length separation and an easier physical implementation, I would recommend a simple string instead. If you don't have extreme space/scale issues, UUIDv4 is good way to get a unique string.

I have requests in my controller, the @Param is the string version of the MongoId.

QUESTION
I am using MongoDB in a reactive Spring Boot application (using Webflux) and I want to do an aggregation on one of our collections but it is just returning an empty list. The code below shows the aggregation and the equivalent query in the command line.
Running the aggregation in the command line works fine and after testing the code it seems to only be the .in(users) part that is not working. So if I just use Criteria.where("_id").is("de28b2fa-4c9b-49fa-b29f-d8ad9d270c36") then a User will be returned.
ANSWER
Answered 2021-Oct-29 at 13:56The following code works based on @prasad_'s comment linking the following post: Spring Mongo Aggregation Project Filter
I just adapted this code to my reactive/webflux solution.
QUESTION
I need all the documents in one of my collections to create association in between my parent model to child. The problem is I only have the string of my ObjectId. So I am finding the object by string and then set via parent.child = foundObject. So, to achieve this I created a private method as below, to not to create DB request each time I need that child object.
ANSWER
Answered 2021-Nov-12 at 00:16I could not find a way to solve this specific problem and I think it's kind of impossible since MongoDB is not a relational DB It's quite hard to collect information at the same time with querying. What I used is "MongoDB views" and this solved a lot. Here is the docs. There you can read and find yourself an approach to figure out your own problem.
