Contacts API - Group Modification

[hendrikstier]

Hello!

I'm currently trying to implement a small script to explicitly set/change a single contact's group. I'm not sure how to use the API.

Reading through http://omz-software.com/pythonista/docs/ios/contacts.html, I find ways to get all groups or those specific to a user, but I do not find information on how to set or change a user's group.

Did anyone already successfully implement this functionality?

Kind regards,

Hendrik

Python introspection to the rescue...

import contacts
print(dir(contacts.get_all_groups()[-1]))  # dir(the last Group in Contacts)

Group has three methods add_member(), get_members(), and remove_member().

Thank you, this is exactly the pointer I need..

A quick follow-up question on groups: I try to move a locally created contact to a group that is supposed to reside on a CardDAV-server.

Is there any way to distinguish between the individual accounts the groups belong to? I ask, because I can iterate over my iCloud-stored groups, but the CardDAV-stored group seems to be missing.

I will try and find my way in reverse (find a user, that is stored in the CardDAV-group and inspect the attributes), but maybe there is already some advice on how to speed up my learning here...

My Pythonista 3 does not have these methods😥

import contacts
p = contacts.find('foo')[0]
g = contacts.Group()
g.name = 'foobar '
g = contacts.add_group(g)
contacts.add_member(p,g)
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: module 'contacts' has no attribute 'add_member'

print(dir(contacts.get_all_groups())[-1])
sort

Where have they gone?

@osamu small errors

import contacts
p = contacts.find('foo')[0]
g = contacts.Group()
g.name = 'foobar '
contacts.add_group(g)
g.add_member(p)
contacts.save()

If after multiple tests, you get multiple groups named "foobar", you can remove them via

import contacts
for g in contacts.get_all_groups():
    print(g.name)
    if 'foobar' in g.name:
        contacts.remove_group(g)
contacts.save()

I got the point. add_member() is a method of object Group().
Thanks!

@cvp one more question.
What is the attribute of People() that stores 'date' field?

[cvp]

@osamu you need to use ObjectiveC to get dates infos, like

from objc_util import *

# ObjectiveC contacts
CNContactStore = ObjCClass('CNContactStore').alloc().init()
CNContact = ObjCClass('CNContact')
Containers = CNContactStore.containersMatchingPredicate_error_(None,None)
for Container in Containers:
    id = Container.identifier()
    predicate = CNContact.predicateForContactsInContainerWithIdentifier_(id)
    # keys not exactly like in Apple doc
    predicate_contacts = CNContactStore.unifiedContactsMatchingPredicate_keysToFetch_error_(predicate, ['familyName', 'givenName', 'middleName', 'dates'], None)
    for contact in predicate_contacts:
        if len(contact.dates()) == 0:
          continue
        name = str(contact.givenName()) + '|' + str(contact.middleName()) + '|' + str(contact.familyName())
        print(name)
        for date in contact.dates():
          print(date)                   # CNLabeledValue
          d = date.value()
          print(d)                      # NSDateComponents
          print(date.label(),':',d.year(),d.month(),d.day())

@cvp Thanks! You know everything!
Oh, that's very challenging...

Sincerely, not at all but I'm retired thus I have a lot of time to spend by searching, trying, bugging 😂
