First off, I’m an intermediate Rails developer who is still learning the
inner workings of Rails… so here is my situation/problem:
I have written a Plugin that accesses a third party API. Within the
Plugin I had multiple classes that inherit from one another. Example:
Old Code (Plugin Classes)
class ApiConn
attr_accessor :api_url, :api_key
def initialize(url, key)
@api_url = url
@api_key = key
end
def api_perform(class_type, method, args)
begin
server = XMLRPC::Client.new3({‘host’ => self.api_url, ‘path’ =>
“/api/xmlrpc”, ‘port’ => 443, ‘use_ssl’ => true})
result = server.call("#{class_type}.#{method}", self.api_key,
args)
rescue XMLRPC::FaultException => e
puts "* Api Error: #{e.faultCode} - #{e.faultString} ***"
end
return result
end
end
class ContactService < ApiConn
def api_contact_add(data)
api_perform(‘ContactService’, ‘add’, data)
end
end
…
Then within my ApplicationController I have this:
Account
def current_account
@current_account ||=
Rails.cache.fetch(“ch:current:account:#{current_subdomain}”){
Account.find_by_subdomain(current_subdomain)
}
end
def app_contact_svc
@app_contact_svc ||=
ContactService.new("#{current_account.api_url}.application.com",
current_account.api_key)
end
Well, this has worked fine. However, as I’ve been going through my
controllers, I’ve noticed that a lot of these calls should be moved to
the models. For example, I have an ActiveRecord model named Contact and
I would like to be able to call api_contact_add from within the instance
of that model. I know I would be able to do that by switching the
plugin to a module.
However, here is the problem: The rails app uses accounts and each
account has a different api_url and api_key. The current_account(see
above) is set by the subdomain being used.
So I guess my question is how I can have module attributes set
specifically for each account through multiple models?
So instead of doing Contact.new(api_url, key) in an initialize statement
for each class that includes the ApiConn module, I would like these
values set once for all models specific to the account.
I hope this make sense
