Steps to reproduce¶

1. Install Foreman 1.6.3
2. Configure OS and templates so CentOS 7.0 will return the following:
   

   $ hammer os info --id 3
   Id:                 3
   Full name:          CentOS 7.0
   Release name:       maipo
   Family:             Redhat
   Name:               CentOS
   Major version:      7
   Minor version:      0
   Partition tables:
       Kickstart default
       Kickstart non-LVM
       Default templates:
       Kickstart default finish (finish)
       Kickstart default iPXE (iPXE)
       Kickstart default PXELinux (PXELinux)
       Kickstart default user data (user_data)
       Kickstart RHEL default (provision)
   Architectures:
       x86_64
   Installation media:
       CentOS mirror
   Templates:
       Kickstart default (provision)
       Kickstart default finish (finish)
       Kickstart default iPXE (iPXE)
       Kickstart default PXELinux (PXELinux)
       Kickstart default user data (user_data)
       Kickstart RHEL default (provision)
   Parameters:
   

3. Login to foreman using the admin account
4. Click Hosts | New Host
5. Click the Operating Systems tab
6. Select x86_64 for the Architecture
7. Select CentOS 7.0 for the Operating System
8. Build mode should be checked (by default)
9. Select CentOS mirror for the Media
10. Select Kickstart Default for the Partition table
11. Click the Resolve button

The Web UI will report

Sorry but no templates were configured.

The production.log will show:

Debug information¶

Debug report uploaded to rsync://theforeman.org/debug-incoming as foreman-debug-xs9Vf.tar.xz.

I was able to get the templates to render correctly using this script:

scl enable ruby193 'ruby <<EOF
  require "mechanize" 

  domain = ENV["WAN_DOMAIN"]
  username = ENV["ADMIN_USERNAME"]
  password = ENV["ADMIN_PASSWORD"]

  agent = Mechanize.new
  agent.cert = "/var/lib/puppet/ssl/certs/foreman.#{domain}.pem" 
  agent.key = "/var/lib/puppet/ssl/private_keys/foreman.#{domain}.pem" 
  agent.agent.http.ca_file = "/var/lib/puppet/ssl/certs/ca.pem" 

  login_page = agent.get "https://foreman.#{domain}/users/login" 
  login_page.form_with(:action => "/users/login") do |form|
    form["login[login]"] = username
    form["login[password]"] = password
  end.submit

  host_page = agent.get "https://foreman.#{domain}/hosts/new" 
  host_page = host_page.form_with(:action => "/hosts") do |form|
    form["host[architecture_id]"] = 1
    form["host[location_id]"] = 1
  end.submit

  host_page = host_page.form_with(:action => "/hosts") do |form|
    form["host[operatingsystem_id]"] = 3
    form["host[location_id]"] = 1
  end.submit

  params = {}
  host_page = host_page.form_with(:action => "/hosts") do |form|
    form["host[medium_id]"] = 1
    form["host[operatingsystem_id]"] = 3
    form["host[architecture_id]"] = 1
    form["host[use_image]"] = false
  end.submit

  host_page.form_with(:action => "/hosts").fields.each do |field|
    params[field.name] = field.value
  end
  params["provisioning"] = "build" 

  page = agent.post("https://foreman.#{domain}/hosts/template_used", params)
  if page.link_with(:text => /Kickstart default PXELinux/).nil? ||
     page.link_with(:text => /Kickstart default finish/).nil? ||
     page.link_with(:text => /Kickstart default iPXE/).nil? ||
     page.link_with(:text => /Kickstart RHEL default/).nil? ||
     page.link_with(:text => /Kickstart default user data/).nil?
    puts "Failed" 
    exit 1
  else
    puts page.inspect
    exit 0
  end
EOF'

The difference between the working and failing cases seems to be where the operatingsystem_id is specified in the hash. In the passing case,
operatingsystem_id is specified as a key in the host hash. In the failing case, operatingsystem_id is specified as a key in the hostgroup
hash, which is a key parallel to the host key. That is:

• Working: { "host" => { "operatingsystem_id" => 3 } }
• Failing: { "host" => { }, "hostgroup" => { "operatingsystem_id" => 3 } }
