kandi X-RAY | dynamoid Summary
Dynamoid is an ORM for Amazon's DynamoDB for Ruby applications. It provides similar functionality to ActiveRecord and improves on Amazon's existing HashModel by providing better searching tools and native association support. DynamoDB is not like other document-based databases you might know, and is very different indeed from relational databases. It sacrifices anything beyond the simplest relational queries and transactional support to provide a fast, cost-efficient, and highly durable storage solution. If your database requires complicated relational queries and transaction support, then this modest Gem cannot provide them for you, and neither can DynamoDB. In those cases you would do better to look elsewhere for your database needs.

QUESTION
I added gem 'bitfinex-rb' in rails gem file, When I do bundle install, I got below mentioned error:
...ANSWER
Answered 2018-Jun-29 at 13:36This is because kucoin 0.1.1 requires faraday >= 0.13 and bitfinex-rb 0.1.0 requires faraday ~> 0.9.2 (so >= 0.9.2 and <= 0.10). At least in Ruby Gems there is no higher version of bitfinex-rb so that you could update it. And the other version of kucoin (0.1.0) also requires faraday >= 0.13. So you can not install both gems (kucoin and bitfinex-rb) at the same time, because of the dependency. Bundle try to resolve the dependencies, but it can only do it if it is possible.
QUESTION
I'm trying to get Clearance to work with AWS Dynamo as the back-end store. The problem I'm having is that I can't get Clearance to not do the email-uniqueness validation, which it can't do because it's not able to do standard ActiveRecord uniqueness validations via a SQL query.
According to the comments in the code, I should be able to have my User
object return email_optional?
true
, and that should disable the uniqueness validation on emails. So I have:

does not trigger validations. Therefore the error cannot be connected to the validations itself.
At the moment your User
model is kind of both: A subclass of ActiveRecord::Base
and it behaves like a Dynamoid::Document
.
