Hi, my name is Victor, and I'm a programmer and developer for an Interactive agency in China. This is my first time working on a Zope-based project. Due to my lack of Zope experience, I've been getting into some problems, and I hope your experience can help me. My problem is: In my HR system,I have a Joblisting class and a Person class, and that Joblisting class is the container class of the Person. In my development process I have saved my Person information in it's parent class Joblisting, but I do not know how to access the sub object of it(person).I can only add use the method self._setObject(newId, newPerson) to add a new person object.But how can I access a Person's information, such as the name or password? I use self.objectIds like this,and want to check the name and password to fit the person object that have been already added in. The error is: Error Type: AttributeError Error Value: firstname def login(self, name, password): """ Use this method to allow user to login""" personNumber = 1 list = self.objectIds(['Person']) ++++++++++++++++++++++++++ while 1: if ((list.firstname == name) & (list.password == password)): return MessageDialog(title='Edited', message='You has been already registed.', action ='./manage_main', ) else: return MessageDialog(title='Error', message='You must registed first!.', action ='./manage_main', ) class Person( Folder ): meta_type='Person' id ='Person' icon = 'misc_/Poll/q' title = 'Person Object' # Specify definitions for tabs: manage_options=( .... ) def __init__(self, id, firstname, lastname, password, birthday, idnumber, ge nder, emailaddress, postaladdress, address, city, postalcode, country, telephone , beeper, resume): self.id = id self.firstname = firstname self.lastname = lastname self.password = password .....
