Question

i have this in my template

<% @clients.each do |client| %>
<li><%= link_to client.name, :controller => "client", :action => "show", :id => client.id %></li>
<%=YAML::dump(client.lastfull)%>
<% end %>

where client looks like this:

class Client < ActiveRecord::Base
        set_table_name 'client'
        alias_attribute :id, :clientid
        set_primary_key :clientid


        has_many :jobs, :foreign_key => 'clientid', :order => 'starttime DESC'

        def lastfull
                jobs.first
        end
end

this works and this is output :

--- !ruby/object:Job attributes: jobid: "81" name: dobrak comment: "" endtime: 2012-06-20 10:15:04

But when i try to read any of the attributes i get error:

undefined method `jobid' for nil:NilClass

Job class:

class Job < ActiveRecord::Base
        attr_accessor :jobid

        set_table_name 'job'
        belongs_to :client

        has_one :status, :primary_key => 'jobstatus', :foreign_key => 'jobstatus'
end

i tried to add method jobid which return attribute and adding attr_accessor, but nothing worked for me. Any suggestions? Thank you.

It looks like there are clients without any jobs. What happens if you change the line to something like <%= client.lastfull.present? ? YAML::dump(client.lastfull.jobid) : 'client has no jobs' %>? You can also take a look at Object#try
