This is a requests backend provider for the Planning Center website. It provides missing functionality for adding and editing groups which is not yet in the official API.
All access to the website is provided
through the planning_center_backend.planning_center.PlanningCenterBackend object.
This object serves as the attachment point for multiple API sub-nodes which may be used to access
the various functionality once login is performed.
To login to the website, use the PlanningCenterBackend.login method. An example is shown below.
from planning_center_backend import planning_center
username = 'my_user'
password = 'my_password'
backend = planning_center.PlanningCenterBackend()
success = backend.login(username, password)
if success:
print('Successfully logged in!')
else:
print('Failed to log in')The PlanningCenterBackend.logged_in field reflects the current login status.
To log out, use PlanningCenterBackend.logout().
The PlanningCenterBackend.people field provides access to the main people API.
The method people.query() provides query access to the API.
There are two ways this query can be performed, using a simple name query, or
by adding advanced search filter parameters.
To do a simple name query, simply pass a string:
# assume logged in already
people_data = backend.people.query('John Smith')In this case, all people with name match "John Smith" will be returned.
The planning_center_backend.people.PeopleQueryExpression object provides advanced functionality.
For example, here we will search for a John Smith who is Male and a site admin.
from planning_center_backend.people import PeopleQueryExpression
query_expr = PeopleQueryExpression(
search_name="John Smith",
gender='M',
site_administrator=True
)
people_data = backend.people.query(query_expr)All people have an associated id (primary key) in the Planning Center database. This id is returned as part of the query response. For example
people_data = backend.people.query('John Smith')
# assume the first John Smith is who we want
person = people_data[0]
person_id = person.idIf we know this id, we can use it to get the person's record directly using the get method rather than querying.
person = backend.people.get(person_id)This retrieves the same data record as above.
A lot of relevant details of the person are included in the record result, including
birthday, admin status, creation time, etc.
This data is available on the attributes field of the person object.
people_data = backend.people.query('John Smith')
# assume the first John Smith is who we want
person = people_data[0]
# get John's birthday
birthday = person.attributes.birthdateThe PlanningCenterBackend.groups field provides access to the groups API functionality.
To create a group, use the create() method, passing the name and optional group type.
Group types are provided in the planning_center_backend.groups.GroupType enum.
The default type is SmallGroup.
# create a new small group
my_group = backend.groups.create('My Group')# create an online group
from planning_center_backend.groups import GroupType
my_group = backend.groups.create('My Group', GroupType.Online)The create method returns a group API object that may be used to manipulate the group.
API objects for existing groups may also be retrieved using the query method.
Groups may be filtered by name, or if the name is omitted, all groups will be returned.
# Query a specific group
# a list is returned, here we get the first match
# if the group is not found, this would fail
my_group, *_ = backend.groups.query('My Existing Group')# Query all groups
all_groups = backend.groups.query()If the numeric group identifier is known, the get method may be used to get the API object directly.
(If on the website, the group id is the number after groups/ in the URL,
i.e. 1234 in 'https://groups.planningcenteronline.com/groups/1234/members)
)
# Get a specific group by id
my_group = backend.groups.get(1234)Once a group API object has been retrieved via either creation, query, or get methods, one can manipulate this object to configure the group.
The most basic interaction with the group is to change settings such as description, name, location, etc. Most settings are exposed as properties on the Group API object. Here are some basic examples of reading and writing these properties.
from planning_center_backend.groups import GroupObject, GroupType
my_group: GroupObject = backend.groups.get(1234)
# Read properties
old_name = my_group.name
old_description = my_group.description
# Write properties
# Change name
my_group.name = 'Better Name'
# Add/change description
# The description is provided in an HTML box in the website, thus the <div>
# presumably other HTML formatting is valid here
my_group.description = '<div>New Description</div>'
my_group.schedule = 'Every Friday'
# reset the group type
my_group.group_type = GroupType.SmallGroup
my_group.contact_email = '[email protected]'There is a large list of setting properties and not all are demonstrated here.
Refer to the planning_center_backend.groups.GroupObject documentation for a full listing.
Most things that can be configured through the website settings page are implemented.
Some values may be read-only.
In order to keep the cached group information up to date with the website, every time a
group property is changed, all group data is reloaded from the web.
If the user wishes to change many properties at once in his code, this may not be
desirable behavior from a performance standpoint.
The auto-refresh behavior can be managed using the auto_refresh property of the GroupObject.
from planning_center_backend.groups import GroupObject
my_group: GroupObject = backend.groups.get(1234)
# Write several properties without auto-refresh
my_group.auto_refresh = False
my_group.name = 'Better Name'
my_group.description = '<div>New Description</div>'
my_group.schedule = 'Every Friday'
# turn back on auto refresh
my_group.auto_refresh = TrueA context manager no_refresh is also provided to assist with this behavior.
This manager disables refresh in the block and returns it to its original setting outside the block.
from planning_center_backend.groups import GroupObject
my_group: GroupObject = backend.groups.get(1234)
# Write several properties without auto-refresh
with my_group.no_refresh():
my_group.name = 'Better Name'
my_group.description = '<div>New Description</div>'
my_group.schedule = 'Every Friday'
# refresh is restored here
assert my_group.name == 'Better Name'Refresh can be manually performed while auto-refresh is disabled using the refresh method.
from planning_center_backend.groups import GroupObject
my_group: GroupObject = backend.groups.get(1234)
# Write several properties without auto-refresh
with my_group.no_refresh():
my_group.name = 'Better Name'
my_group.refresh()
# using the new name here
my_group.description = f'<div>{my_group.name} New Description</div>'To add a group member, first look up the member's id using the people API.
Then the person can be added to the group using add_member.
from planning_center_backend.groups import GroupObject
member_data = backend.query.people('John Smith')
if not member_data:
# did not find the person
raise ValueError
# assume first query result is correct
member_id = member_data[0].id
# Add the person to the group
my_group: GroupObject = backend.groups.get(1234)
my_group.add_member(member_id)Members can be set as leader, and email notification of the membership can be enabled via appropriate flags.
my_group.add_member(member_id, leader=True, notify=True)An existing member list can be retrieved via the memberships property.
This property returns a list of API query object results representing the group members.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
members = my_group.memberships
for member in members:
# print a list of member names by id
print(f'Group Member {member.id}: {member.attributes.first_name} {member.attributes.last_name}')A particular member's membership information can be retrieved with get_member by supplying their Person id.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
this_member = my_group.get_member(member_person_id)The member's permissions can be updated with update_member using their Person id.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
# make this person a new leader
my_group.update_member(new_leader_id, leader=True)
# allow this person to take attendance and notify him of change
my_group.update_member(new_attendance_taker_id, attendance_taker=True, notify=True)Members can be removed with delete_member (also using Person id).
from planning_center_backend.groups import GroupObject
my_group: GroupObject
# remove this member
my_group.delete_member(former_member_id)
# remove this member and notify him via email
my_group.delete_member(former_member_id_2, notify=True)
# remove this person and do not error even if not in the group
my_group.delete_member(former_member_id_3, missing_ok=True)To add/remove tags in a group, the tag id must first be identified.
The available tags may be queried using groups.tag.query() on the Group API provider.
from planning_center_backend.planning_center import PlanningCenterBackend
backend: PlanningCenterBackend
# find the tag corresponding to meeting on Sunday
result = backend.groups.tags.query('Sunday')
if not result:
# we didn't find the tag we want
raise ValueError
# assume first result is correct
sunday_tag = result[0]
sunday_tag_id = tag.id# get a list of all tags
all_tags = backend.groups.tags.query()At this time, new tag creation is not supported and should be performed manually through the website.
To view which tags are currently assigned to a group, use the tags property of the group object.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
for tag in my_group.tags:
print(f'Group Tag: {tag.attributes.name}')To add a tag, you can use either numeric tag id (int), tag name (str) or TagData object returned from query.
from planning_center_backend.groups import GroupObject
from planning_center_backend.planning_center import PlanningCenterBackend
backend: PlanningCenterBackend
my_group: GroupObject
result = backend.groups.tags.query('Sunday')
sunday_tag = result[0]
sunday_tag_id = tag.id
# all equivalent methods of adding Sunday tag
my_group.add_tag(sunday_tag_id)
# this will only work if querying the name Sunday has exactly one match
my_group.add_tag('Sunday')
my_group.add_tag(sunday_tag)You can check if a group has a given tag in a similar way, by int id, str name, or TagData object
# all equivalent methods of querying Sunday tag
has_sunday_tag = my_group.has_tag(sunday_tag_id)
# this will only work if querying the name Sunday has exactly one match
has_sunday_tag = my_group.has_tag('Sunday')
has_sunday_tag = my_group.has_tag(sunday_tag)Deleting a tag is done analogously using delete_tag.
The default is to silently ignore a tag that does not exist.
# all equivalent methods of querying Sunday tag
my_group.delete_tag(sunday_tag_id)
# in this case, throw error if the tag did not exist
my_group.delete_tag('Sunday', missing_ok=False)
my_group.delete_tag(sunday_tag)Group location management is somewhat complex because locations include latitude and longitude data. On the website, this is provided via a Google Maps API integration. If the user wishes to provide similar functionality (address lookup via Google Maps), he should create a Google Maps account and set up an API key.
To query all locations available for a group to use, use locations.query on the group object.
(Some locations are shared between groups and some are group-specific.)
from planning_center_backend.groups import GroupObject
my_group: GroupObject
# Print address of all available locations
for loc in my_group.locations.query():
print(f'Location {loc.name} ({loc.id}) Address: {loc.formatted_address}')Note that this API is a v1 API, so there is no "attributes" object, all the location attributes
are simply on the base query result. Location id is found in the id field of the query result.
Unfortunately, there is no way to filter queries in the request. Neither is there a way to retrieve one record by location id. Therefore, the developer is cautioned to use this query feature wisely and cache results as possible in order to maintain performance.
The current location id is given by the location_id field for the group.
To set a new location, set the location id.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
# query all locations
all_locations = my_group.locations.query()
# find the desired location in query result
desired_location_name = "Joe's House"
desired_location = [_ for _ in all_locations if _.name == desired_location_name][0]
# set the new location
my_group.location_id = desired_location.idTo create a new location for the Group, there are two methods, a location based on Google Maps API query result, or a custom location (with manual latitude and longitude). To facilitate this, a Google Maps API stub integration is provided.
from planning_center_backend.maps import Maps
from planning_center_backend.groups import GroupObject
my_group: GroupObject
maps = Maps(api_key='your_google_api_key')
places = maps.find_place_from_text('Empire State Building')
# assume first result is what you want
place = places[0]
geocodes = maps.geocode_from_place_id(place.place_id)
# again, assume first result is correct
geocode = geocodes[0]
location_id = my_group.locations.create(
name='Empire State Building',
geocode_data=geocode,
shared=True, # allow sharing with other groups
)
# assign this new location to the group
my_group.location_id = location_idAlternatively, if the latitude and longitude are known, one can use custom location without Google API.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
location_id = my_group.locations.create_custom(
name='Empire State Building',
formatted_address='20 W 34th St., New York, NY 10001',
latitude=40.74850,
longitude=-73.98566,
shared=True, # allow sharing with other groups
)
# assign this new location to the group
my_group.location_id = location_idNote that creating a new location does not assign it as the group location, it only adds it to list of available group locations.
To delete a group location, use locations.delete with the location id.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
old_location_id = my_group.location_id
my_group.location_id = new_location_id
# delete the old location
my_group.locations.delete(old_location_id)Group events are currently only read-only accessible. Creating and managing events may be available in a future version.
To view all current group events, use the events property.
from planning_center_backend.groups import GroupObject
my_group: GroupObject
# Show all group event names and start times
for event in my_group.events:
print(f'{event.attributes.name} at {event.attributes.starts_at}')
