URL Mixin


Use the class constant URLS for a array of URLs that should be added to InvenTrees URL paths or override the plugin.setup_urls function.

The array has to contain valid URL patterns as defined in the django documentation.

class MyUrlsPlugin(UrlsMixin, InvenTreePlugin):

    NAME = "UrlsMixin"

    URLS = [
        url(r'increase/(?P<location>\d+)/(?P<pk>\d+)/', self.view_increase, name='increase-level'),

The URLs get exposed under /plugin/{plugin.slug}/* and get exposed to the template engine with the prefix plugin:{plugin.slug}: (for usage with the url tag).


In this example, when an HTTP request is made to /plugin/{plugin.slug}/increase/.../... the function self.view_increase is called and returns the view to be displayed (step 4 in the Django documentation)


If your plugin will implement and host another webpage, familiarize yourself with Django views. Implementation is exactly the same. A good place to start is the django documentation. Additional InvenTree-specific information is below.

Rendering Views

Rendering templated views is also supported. Templated HTML files should be placed inside your plugin folder in a sub folder called templates. Placed here, the template can be called using the file name and the render command.

Example in context (inside the main plugin python file):

def view_test(self, request):
    return render(request, 'test.html', context)

def setup_urls(self):
    return [
        re_path(r'^test/', self.view_test, name='test')

Implementing the Page Base

Some plugins require a page with a navbar, sidebar, and content similar to other InvenTree pages. This can be done within a templated HTML file by extending the file "page_base.html". To do this, place the following line at the top of your template file.

{% extends "page_base.html" %}

Additionally, add the following imports after the extended line.

{% load static %}
{% load inventree_extras %}
{% load plugin_extras %}
{% load i18n %}


The page_base file is split into multiple sections called blocks. This allows you to implement sections of the webpage while getting many items like navbars, sidebars, and general layout provided for you.

The current default page base can be found here. Look through this file to determine overridable blocks. The stock app offers a great example of implementing these blocks.

Sidebar Block

You may notice that implementing the sidebar block doesn't initially work. Be sure to enable the sidebar using JavaScript. This can be achieved by appending the following code, replacing label with a label of your choosing, to the end of your template file.

{% block js_ready %}
{{ block.super }}
{% endblock js_ready %}


InvenTree uses bootstrap panels to display the page's content. These panels are locate inside the block page_content.


<div class='panel panel-hidden' id='panel-loans'>
    <div class='panel-heading'>
        <div class='d-flex flex-wrap'>
            <h4>{% trans "Loaning Information" %}</h4>
    <div class='panel-content'>
Notice that this example has the panel initially hidden. This is where the enableSidebar('...');' function comes back into play. Panels are enabled according to the labels of items in the sidebar. Each sidebar item must declare a label corresponding to a panel. An example of a sidebar item within with the label loans is below.

{% trans "Loaning" as text %}
{% include "sidebar_item.html" with label='loans' text=text icon="fa-sitemap" %}
Note: This code is assumed to be placed within the sidebar block.

The enableSidebar('...');' function will un-hide the panel with the label panel-... (for this example, panel-loans) and hide all other panels. This allows you to have multiple panels on a page, but only show the panel corresponding to the current selected sidebar item. Whenever you click a sidebar item, it will automatically enable the panel with the corresponding label and hide all other panels.

Additionally, when a panel is loaded, the function onPanelLoad(...) will be called for the associated panel. If you would like to add javascript functionality to a panel after it loads, add the function within the {% block js_ready %} block of your template file.


onPanelLoad('loans', function() {
