CustomFieldCollection

CustomFieldCollection(*, session: AlbertSession)

Bases: BaseCollection

CustomFieldCollection is a collection class for managing CustomField entities in the Albert platform.

This collection provides methods to create, update, retrieve, and list custom fields. CustomFields allow you to store custom metadata on a Project, InventoryItem, User, BaseTask (Tasks), and Lot.

The FieldType used determines the shape of the metadata field's value. If the FieldType is LIST, then the FieldCategory defines the ACL needed to add new allowed items to the given list:

• FieldCategory.USER_DEFINED: allows general users to add items
• FieldCategory.BUSINESS_DEFINED: only admins can add new items to the list

Example

# Creating some custom fields
from albert import Albert
from albert.resources.custom_fields import CustomField, FieldCategory, FieldType, ServiceType
from albert.resources.lists import ListItem
from albert.resources.project import Project

# Initialize the Albert client
client = Albert()

# Define the custom fields

    service=ServiceType.PROJECTS,
    min=1,
    max=1,
    category=FieldCategory.BUSINESS_DEFINED  # Defined by the business
)
justification_field = CustomField(
    name="justification",
    display_name="Project Justification",
    field_type=FieldType.STRING,
    service=ServiceType.PROJECTS,
)

# Create the custom fields
client.custom_fields.create(custom_field=stage_gate_field)
client.custom_fields.create(custom_field=justification_field)
