If Exists, find_or_create returns error.

In this example I will use IRB to connect and create a HG that does not exist. Then I will back out of IRB, run it again, and it will error out.

pry> host_group = Rubix::HostGroup.find_or_create(:name => "My Zabbix Hosts")
=> #<Rubix::HostGroup:0x105a4ffa0
 @id=44,
 @name="My Zabbix Hosts",
 @properties={:name=>"My Zabbix Hosts"}>

Exit out of IRB

pry> exit

Hop back into IRB and run the same command again after connecting.

pry> host_group = Rubix::HostGroup.find_or_create(:name => "My Zabbix Hosts")
NoMethodError: undefined method `map' for nil:NilClass

I cannot reproduce this. What Rubix version are you using? Here's a pry session with latest:

dhruv@silicon:/p/i/rubix$ pry -e 'require "rubix" ; Rubix.connect("http://localhost:8080/api_jsonrpc.php", "admin", "zabbix")'

I am running the latest stable version of Rubix.

$gem search rubix
rubix (0.5.13)

What version of Zabbix are you using? I am running Zabbix Server 2.0.2 (Latest Stable)

Thanks, Ron

Here is your exact pry session in my environment.

No Host Group named "My Zabbix Hosts".

$ pry -e 'require "rubix" ; Rubix.connect("http://zabbix/api_jsonrpc.php", "admin", "password")'
=> #<Rubix::Connection:0x007fe932cd3d90
 @password="password",
 @request_id=0,
 @server=#<Net::HTTP zabbix:80 open=false>,
 @uri=
  #<URI::HTTP:0x007fe932cd3a70 URL:http://zabbix/api_jsonrpc.php>,
 @username="admin">
[2] pry(main)> host_group = Rubix::HostGroup.find_or_create(:name => "My Zabbix Hosts")
I, [2012-08-21T13:38:28.626185 #24547]  INFO -- : Created Zabbix HostGroup My Zabbix Hosts
=> #<Rubix::HostGroup:0x007fe932906f28
 @id=45,
 @name="My Zabbix Hosts",
 @properties={:name=>"My Zabbix Hosts"}>
[3] pry(main)> exit

Now Host Group "My Zabbix Hosts" exists.

$ pry -e 'require "rubix" ; Rubix.connect("http://zabbix/api_jsonrpc.php", "admin", "password")'
=> #<Rubix::Connection:0x007f89dbce2400

Oh man! I bet it's the Zabbix server version! I've only ever tested Rubix with Zabbix <2.0. There are some serious changes to the API introduced in 2.0 that Rubix doesn't know how to deal with.

It's on my plate for Rubix 0.6 to support Zabbix 2.0 but it's not happened yet.
