Config.namespace still adds namespacing even if set to nil #78

I am setting my configuration to the following:

config.adapter = 'aws_sdk_v2'
config.namespace = nil
config.warn_on_scan = true
config.read_capacity = 5
config.write_capacity = 5

However, when i get the result I am getting the following:


In this example my table is called "tableName" however it is still adding the _, I tried setting config.namespace to "" and nil but it did not work.

Is this an error or did I just misunderstood the documentation?

It seems to be working fine for me.

require 'dynamoid'
require 'aws-sdk'

Dynamoid.configure do |config|
  config.adapter = 'aws_sdk_v2'
  config.namespace = nil
  config.endpoint = 'http://localhost:8000'

class SampleModel
  include Dynamoid::Document
  table name: 'table_name', key: :email

p SampleModel.table_name

p Dynamoid::adapter.list_tables

p SampleModel.create(email: "")

And also all specs passed on my local.

same problem here!

class Measurement
  include Dynamoid::Document

  table name: 'api_data'
2.3.0 :003 > Measurement.table_name
 => "_api_data"

what version are you using @cignoir?

alexperto commented Jun 16, 2016 edited

it seems like the code is fine, for some reason the latest version didn't work for me, when I used a forked repo it worked perfectly. Anyways, I created a PR to refactor the table-namespacing stuff

bundle show dynamoid

I used v1.1.0 which is directly cloned via github (not rubygems).

I guess the difference of v1.1.0 between github and rubygems causes this problem. The namespacing problem was fixed on Mar 12, 2016. However, the version on rubygems not updated since December 30, 2015.

Hello, I suggest that it is time to bump and deploy new version ๐Ÿš€


thanks for looking at it @cignoir,
I temporary fixed it by doing:

gem "dynamoid", git: ""
bglusman commented Aug 7, 2016

If anyone else needs a gem based distribution, we're working on a new one but I had related issue and created dynamoid-edge gem release of a current master snapshot a few months back that will probably fix your issue @tvmendoza , but hopefully @pboling or I will be able to get a new gem release out on the official gem soon.

archonic commented Sep 2, 2016

Master branch indeed fixes it, but I'm hoping the release with that fix is pushed to rubygems before we're ready to release our feature. Don't want to be bundling an unversioned branch in production!

pboling commented Sep 4, 2016 edited

@bglusman @archonic I am going to release a minor update from current master, to get this particular fix out, along with the rest of the fixes on master. We have a lot of other work to do that will need to be in further releases as well, but we might as well release where we are at now.

Been trying to get specs passing, and finally won the battle with rspec-retry gem. Also made a few other improvements. 1.2.0 coming shortly.
#100 Please review and comment!
