## LocateMixin

The `LocateMixin` class enables plugins to "locate" stock items (or stock locations) via an entirely custom method.

For example, a warehouse could be arranged with each individual 'parts bin' having an audio-visual indicator (e.g. RGB LED and buzzer). "Locating" a particular stock item causes the LED to flash and the buzzer to sound.

Another example might be a parts retrieval system, where "locating" a stock item causes the stock item to be "delivered" to the user via a conveyor.

The possibilities are endless!

### Web Integration

### App Integration

If a locate plugin is installed and activated, the [InvenTree mobile app](../../app/index.md) displays a button for locating a StockItem or StockLocation (see below):

{{ image("plugin/app_locate.png", "Locate stock item from app", maxheight="400px") }}

### Implementation

Refer to the [InvenTree source code]({{ sourcefile("src/backend/InvenTree/plugin/samples/locate/locate_sample.py") }}) for a simple implementation example.

### Sample Plugin

A simple example is provided in the InvenTree code base:

::: plugin.samples.locate.locate_sample.SampleLocatePlugin
    options:
        show_bases: False
        show_root_heading: False
        show_root_toc_entry: False
        show_source: True
        members: []
