ORM for Custom Objects de Zendesk

Mercury (ORM Zendesk CustomObjects)

Mercury is a Python ORM (Object-Relational Mapping) designed to integrate seamlessly with the Zendesk Custom Objects API. It provides a Django-like interface for defining, managing, and interacting with Zendesk custom objects and records, simplifying the communication with Zendesk's API.

Key Features

• Custom Object Representation: Define Zendesk custom objects using Python classes.
• Automatic Record Management: Built-in methods for creating, reading, updating, and deleting records via Zendesk's API.
• Support for All Field Types: Compatible with all Zendesk custom field types including name, text, dropdown, checkbox, date, integer, and more.
• Automatic Object Creation: Automatically create Zendesk custom objects and fields from Python class definitions.
• Easy Record Operations: Simple API to manage custom object records, with built-in support for querying, filtering, and pagination.
• Support field Name autoincrement and unique constraint: Supports automatic field name incrementation and enforcement of unique constraints.

Installation

pip install mercury-orm
# add variables in .env or:
export ZENDESK_SUBDOMAIN=<your_zendesk_subdomain>.
export ZENDESK_API_TOKEN=<your_zendesk_api_token>.
export ZENDESK_EMAIL=<your_zendesk_email>.

CRUD Operations with Records

Mercury ORM provides simple methods for performing CRUD (Create, Read, Update, Delete) operations on Zendesk custom object records. Below are examples of how to manage records in your custom objects.

Creating a CustomObjects

class Product(CustomObject):
    name = fields.TextField("name")
    code = fields.TextField("code")
    description = fields.TextareaField("description")
    price = fields.DecimalField("price")
    active = fields.CheckboxField("active")
    voltage = fields.DropdownField("voltage", choices=["220", "110", "Bivolt"])

Creating a Custom Object and Fields in Zendesk

Once you define the custom object class, you can create it in Zendesk using ZendeskObjectManager. This will automatically create the custom object and its fields in Zendesk.

from mercuryormc.zendesk_manager import ZendeskObjectManager

# Create the custom object and fields in Zendesk
manager = ZendeskObjectManager()
manager.create_custom_object_from_model(Product)
# or
manager.get_or_create_custom_object_from_model(Product)

Record Manager

Each custom object class is automatically assigned a RecordManager that handles interaction with the Zendesk API. The RecordManager allows you to:

• Create records: Product.objects.create(**kwargs)
• Get a single record: Product.objects.get(id=1)
• Filter records: Product.objects.filter(active=True)
• Delete records: Product.objects.delete(id=1)
• Retrieve all records: Product.objects.all()
• Search all records: Product.objects.search(word="something")
• Find records: Product.objects.find(filters=filters)
• Find records with pagination: Product.objects.find_paginated(filters=filters)

Creating a Record

You can create a new record by instantiating your custom object and calling the save() method:

product = Product(name="Sample Product", code="12345", price=99.99, active=True)
product.save()

#or
Product.objects.create(name="Sample Product", code="12345", price=99.99, active=True)

Retrieving a Record

You can retrieve an individual record by using the get() method:

retrieved_product = Product.objects.get(id=product.id)

Updating a Record

To update a record, modify its attributes and call the save() method again:

retrieved_product.price = 89.99
retrieved_product.save()

Deleting a Record

To delete a record from Zendesk, call the delete() method on the object:

retrieved_product.delete()

Querying and Filtering Records

You can retrieve all records or filter them based on certain criteria.

all_products = Product.objects.all()
filtered_products = Product.objects.filter(active=True)
last_object = Product.objects.last()
find_products = Products.objects.find(filters=filters)
find_products_paginated = Products.objects.find_paginated(filters=filters)

Find Method Explanation

The find method is based on Zendesk's filtering options for custom objects. It allows filtering records using logical operators and comparison operators.

Supported Logical Operators

• $or
• $and

Supported Comparison Operators

Custom Fields:

Custom objects have the following types of custom fields that you can filter on:

Field Type	Supported Operators	Meaning (in same order)
Checkbox	$eq	is
Date	$eq, $noteq, $gt, $gte, $lt, $lte, $exists	is, is not, after, after or on, before, before or on, present, in range
Decimal	$eq, $noteq, $gt, $gte, $lt, $lte, $exists, $in, $notin	is, is not, after, after or on, before, before or on, present, in, not in
Drop-down	$eq, $noteq, $contains, $notcontains, $exists	is, is not, contains, not contained, present
Integer	$eq, $noteq, $gt, $gte, $lt, $lte, $exists, $in, $notin	is, is not, after, after or on, before, before or on, present, in, not in
Lookup Relationship	$eq, $noteq, $exists	is, is not, present
Multi-line text	$eq, $noteq, $contains, $notcontains, $exists	is, is not, contains, not contained, present
Multi-select	$eq, $noteq, $contains, $notcontains, $exists, $in, $notin	is, is not, contains, not contained, present, in, not in
Text	$eq, $noteq, $contains, $notcontains, $exists	is, is not, contains, not contained, present

Standard Fields

Custom objects have the following standard fields that you can filter on:

Field Type	Supported Operators	Meaning (in same order)
created_at	$gt	after
created_by_user	$eq	is equal to a user ID
external_id	$eq	is equal to an external ID
name	$contains	contains
updated_at	$gt	after
updated_by_user	$eq	is equal to a user ID

Filter Examples

Single Comparison

filters = {
    {"custom_object_fields.price": {"$eq": "12"}}
}

In this case, records where the field named price is equal to 12 will be returned.

OR Comparison

filters = {
    "$or": [
        {"name": {"$contains": "value"}},
        {"updated_at": {"$gt": "2024-12-13"}}
    ]
}

In this case, records where the name contains value or updated_at is greater than 2024-12-13 will be returned

AND Comparison

filters = {
    "$and": [
        {"name": {"$contains": "value"}},
        {"updated_at": {"$gt": "2024-12-13"}}
    ]
}

In this case, records where the name contains value and updated_at is greater than 2024-12-13 will be returned.

Combined OR and AND Comparison

filters = {
    "$or": [
        {"name": {"$contains": "value"}},
        {"updated_at": {"$gt": "2024-12-13"}}
    ],
    "$and":[
        {"custom_object_fields.price": {"$eq": "12"}},
        {"custom_object_fields.origin": {"$eq": "BR"}}
    ]
}

In this case, records matching the OR conditions (name contains value or updated_at is greater than 2024-12-13) and the AND conditions (price equals 12 and origin equals BR) will be returned.
