(Looking for a maintainer) MongoDB support for rom-rb

ROM::Mongo

MongoDB support for Ruby Object Mapper

Installation

Add this line to your application's Gemfile:

gem 'rom-mongo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rom-mongo

Usage

See spec/integration/gateway_spec.rb for a sample usage.

Issues

Issues should be reported in the main ROM repository, https://github.com/rom-rb/rom/issues

License

See LICENSE file.

rom-mongo's Issues

Switch to driver for queries exclusively

It turned out origin gem has been merged into mongoid codebase and is now considered a private API. Because of this we need to rely only on the driver. If we want a fancy query DSL, we need to build it ourselves.

Mongo::Struct constructor_type is broken

Hi, folks!

I assume ROM::Mongo::Struct was broken after this commit: https://github.com/dry-rb/dry-struct/pull/55/files

rom-mongo/lib/rom/mongo/struct.rb

Lines 4 to 8 in cc335a4

	module Mongo
	class Struct < ROM::Struct
	constructor_type :symbolized
	end
	end

I think we can just remove this option and inherit :permissive option from ROM::Struct.
I would love to make PR as well.

Relation with association can not be finalized

Relation can not be finalized if it has at least one defined association.

It can be fixed by defining self own finalize_associations! method for ROM::Mongo::Schema or inheriting this class from ROM::Memory::Schema.

RomStruct should have dynamic fields schema

I working with ROM-mongo on a mongo DB that have dynamic fields on each collection, I defined a schema for the collection, but ROM struct raises an exception when trying to instantiate a new struct for document with a missing field. I think the mongo schema should be dynamic and accept missing fields.

when is the release planned on rubygems.org for rom-mongo to work with rom 4.X ?

Thank's for you help:

Support raw query selectors in rom-mongo

From @kwando on August 14, 2015 10:37

rom-mongo needs a way to query a collection with a raw query selector, right now you are forced to use the query DSL.

Get it to work with Rom::Repository

Tried to use this adapter with the guide to repositories on rom-rb-org only to find it does not work. Read up a bit and rom-sql seems to work with repositories but i can't find out how/why. Any pointers?

Adapter identifier not configured

As per the documentation on http://rom-rb.org/guides/adapters/how-to/ an adapter specific relation class has to have a adapter identifier configured.

ROM v5.0.2 support

Hello !

I want to use ROM with MongoDB (legacy choice 👎)

The problem is that I don't know where to start to update this gem.

Thanks for your help !

update gem rom version

I want to install rom-mongo beside rom-sql on the Gemfile. I had an error on bundle install.

Bundler could not find compatible versions for gem "rom":
  In snapshot (Gemfile.lock):
    rom (= 3.0.1)

  In Gemfile:
    rom

    rom-mongo was resolved to 0.0.1, which depends on
      rom (~> 0.3)

    rom-sql was resolved to 1.0.2, which depends on
      rom (~> 3.0)

    rom-sql was resolved to 1.0.2, which depends on
      rom (~> 3.0)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

my Gemfile contains

gem 'rom-sql'
gem 'rom-mongo'
gem 'rom-repository'

I solved the problem by using gem 'gem 'rom-mongo', git: 'https://github.com/rom-rb/rom-mongo'
please update the gem version.

Current version of origin gem displays warning

Origin gem displays the warning:

/Users/wafcio/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/origin-2.3.0/lib/origin/aggregable.rb:26: warning: instance variable @aggregating not initialized

It can be hard to fix because origin gem is legacy right now.
