I'm gonna add some information!
I'm developing a Jenkins plugin in Ruby. You're supposed to be able
to
configure every node that connects to the server so that an email is
sent to a specified address when the node loses its connection to the
master. 'EmailNodeProperty' adds a field to enter an email address:
#
# Save an email property for every node
#
class EmailNodeProperty < Jenkins::Slaves::NodeProperty
require 'java'
import 'hudson.util.FormValidation'
display_name "Email notification"
attr_accessor :email
def initialize(attrs = {})
@email = attrs['email']
end
def doCheckEmail value
puts " ENP.doCheckEmail:#{value}"
end
end
When you configure a node, there's a field named 'email' where you
can
enter an email address. I want this field to be validated when you
enter an address.
When you save the configuration, an 'EmailNodeProperty' is created
whence (that's right) you can access the email address.
'MyComputerListener's 'offline' method gets called when a node loses
its connection:
class MyComputerListener
include Jenkins::Slaves::ComputerListener
include Jenkins::Plugin::Proxy
def online(computer, listener)
end
def offline(computer)
#Do nothing when the Master shuts down
if computer.to_s.match('Master') == nil
list = computer.native.getNode().getNodeProperties()
proxy = list.find {"EmailNodeProperty"}
if proxy.is_a?(Jenkins::Plugin::Proxy)
rubyObject = proxy.getTarget()
email = rubyObject.email #<= Accesses the email
from EmailNodeProperty
end
end
[...]
end
end
'MyComputerListener' finds the email address and sends an email.
Does anybody know if it is possible to validate the form in Ruby?
According to the Jenkins wiki (https://wiki.jenkins-ci.org/display/
JENKINS/Basic+guide+to+Jelly+usage+in+Jenkins), this is what's
supposed to be implemented (FIELD is supposed to be exchanged for the
field name, so I guess it should be 'doCheckEmail'):
public FormValidation doCheckFIELD(@QueryParameter String value)
{
if(looksOk(value))
return FormValidation.ok();
else
return FormValidation.error("There's a problem here");
}
How would you do this in Ruby? Where should the method be
implemented?
In 'EmailNodeProperty' or in 'MyComputerListener'? How do you handle
the QueryParameter? The @ would make it an intstance variable in
Ruby.
(What is a Queryparameter?)
Any help would be much appreciated!
