# Creating a Ruby gem that talks to another gem

I am working on creating an interface gem that works with the Jira-Ruby gem.

I have several questions and would like a general review for both my code and my attempt at creating a gem (I've never written one before). Any advice on where to go next would also be appreciated.

File structure:

jira_interface
lib
jira_interface
config.rb
version.rb
app_interface.rb
jira_interface.rb
jira_interface.gemspec
#...etc files, I used bundle's gem command to set up


My main module (jira_interface.rb) looks like this:

require "jira_interface/version"
require "jira"
require "jira_interface/config"
require "jira_interface/app_interface"

module JiraInterface

def get_jira_client
@client = Jira::Client.new(USERINFORMATION)
end

def get_project(project_name)
@client.Project.find(project_name)
end

end


And my app_interface.rb looks like this:

class AppInterface < JiraInterface
before_filter :get_jira_client

def create_issue(issue_desc, project)
issue = @client.Issue.build
issue.save({"fields"=>{"summary"=> issue_desc, "project"=> {"id" => project.id}, "issuetype"=> {"id"=> "1"}}})
end

def update_issue(issue_id)
issue = @client.Issue.find(issue_id)

comment.save({"body"=> "This happened again at #{Date.time}"})
end

def get_issues(issue_desc, project_name)
project = get_project(project_name)

if project.issues.detect { |issue| issue.fields['summary'].include?(issue_desc) }
update_issue(issue.id)
else
create_issue(issue_desc, project)
end
end

end


The goal is pretty simple: call get_issues() from the rails app when an error happens. If the error is already documented, post a comment saying that it happened again. If it's not, then create a new issue.

To the best of my knowledge, this should work because I've been following the examples found online. However, I've been having a heck of a time just testing it. If anyone could suggest a good way of testing this, that would be much appreciated.

• Aside from what I posted in my answer, your approach looks great. Naming could be improved, but like they say, it is hard. Keep the good work up! – CMW Oct 22 '13 at 21:16
• does my answer help at all? If not, I'd very much appreciate any feedback. – CMW Oct 28 '13 at 20:40
