title: Report Mixin
|
|
---
|
|
|
|
## ReportMixin
|
|
|
|
The ReportMixin class provides a plugin with the ability to extend the functionality of custom [report templates](../../report/report.md). A plugin which implements the ReportMixin mixin class can add custom context data to a report template for rendering.
|
|
|
|
### Add Report Context
|
|
|
|
A plugin which implements the ReportMixin mixin can define the `add_report_context` method, allowing custom context data to be added to a report template at time of printing.
|
|
|
|
### Add Label Context
|
|
|
|
Additionally the `add_label_context` method, allowing custom context data to be added to a label template at time of printing.
|
|
|
|
### Example
|
|
|
|
A sample plugin which provides additional context data to the report templates can be found [in the InvenTree source code](https://github.com/inventree/InvenTree/blob/master/InvenTree/plugin/samples/integration/report_plugin_sample.py):
|
|
|
|
```python
|
|
"""Sample plugin for extending reporting functionality"""
|
|
|
|
import random
|
|

|
from plugin import InvenTreePlugin
|
|
from plugin.mixins import ReportMixin
|
|
from report.models import PurchaseOrderReport
|
|
|
|

|
|
|
|
# We can add any extra context data we want to the report
|
|
|
|
# Generate a random string of data
|
|
context['random_text'] = ''.join(random.choices('abcdefghijklmnopqrstuvwxyz', k=20))
|
|
|
|
# Call a custom method
|
|
context['random_int'] = self.some_custom_function()
|
|
|
|
# We can also add extra data to the context which is specific to the report type
|
|
context['is_purchase_order'] = isinstance(instance, PurchaseOrderReport)
|
|

|
# We can also use the 'request' object to add extra context data
|
|
context['request_method'] = request.method
