uninitialized constant Airtable::Record::HashWithIndifferentAccess

[dmerand]

Hi,

I've been working on getting this gem to work for some time, and I'm stuck. I'm wondering if the issue is my setup or the gem.

Here's my setup code:

#!/usr/bin/env ruby

require 'airtable'

at_key = 'KEY_REDACTED'
at_base = 'BASE_REDACTED'

@client = Airtable::Client.new(at_key)
@table = @client.table(at_base, "Videos")
@records = @table.records
p @records.inspect

...pretty much straight from the README. When I run that code, I get this error:

/Users/donald/.rbenv/versions/1.9.3-p551/lib/ruby/gems/1.9.1/gems/airtable-0.0.8/lib/airtable/record.rb:33:in override_attributes!': uninitialized constant Airtable::Record::HashWithIndifferentAccess (NameError) from /Users/donald/.rbenv/versions/1.9.3-p551/lib/ruby/gems/1.9.1/gems/airtable-0.0.8/lib/airtable/record.rb:5:ininitialize'

As you can see, I'm using rbenv. I've run this same code on Ruby 1.9.1, 2.2.4, and 2.3.0 and I can't get it to do anything but give me the error you see above. Am I missing something? Or this this a bug?

I downloaded the gem source to my machine and ran the tests, which ran just fine.

There's an unstated dependency on http://apidock.com/rails/ActiveSupport/HashWithIndifferentAccess which is causing this issue. If you add in the activesupport library to your project or otherwise define HashWithIndifferentAccess, this error will go away

[dmerand]

Thanks, that fixes it indeed! For anybody else with this problem, the require line is:

require 'active_support/all'

[yuuki1224]

I've got same trouble and wondering why don't this add require 'active_support/all' into here?
Any reason?

[syrnick]

I'll address that. Is there any reason to not depend on active_support explicitly?

[nesquena]

active_support is a pretty expensive dependency to bring in to a project that doesn't already have it loaded. I wonder if we'd be better off finding an alternate way to make it so we can do @record[:foo] and @record['foo'] produce the same response. That said, easiest solution is to depend explicitly on active_support

[syrnick]

Handling @record[:foo] and @record['foo'] is pretty easy. I'd just store data keyed by the string k, a map from to_key(k) to k and lookup the key if the argument to @record[] is a symbol. I think it'll actually be better, because you'd only be exposed to naming collisions created by to_key when you use an ambiguous symbol.

@record.fields[:foo] and @record.fields['foo'] is a bit more complicated as we'd need an equivalent replacement for HashWithIndifferentAccess. I'm leaning towards checking if it exists and returning one if it does. If you don't have active_support, it'd just work until you try to use @record.fields with a symbol.
