Experimental frontend for argus-server_ as a django app.
Will possibly cease to exist as a separate app if the experiment is deemed successful.
See argus-server_ for more about argus.
Imports django-htmx. See the documentation for django-htmx
for details.
To make sure you do not accidentally work on an old argus-server, do the following:
python -m venv argus-htmxpip install -e .pip install -e .It is now safe to remove argus-server from the venv if you feel like it.
Do this in your workdir, which could be the checked out argus-server_ repo.
This assumes that you have a local settings file (we recommend calling it
"localsettings.py" since that is hidden by .gitignore) as a sibling of
src/.
At the top of this local settings file, copy the contents of
argus.htmx.settings. This will base the settings-file on
argus.site.settings.backend and automatically use
argus.site.utils.update_settings with
argus_htmx.app_config.APP_SETTINGS to set/overwrite some settings and
mutate others. Note the usage of globals(); due to this, inheriting from
argus.htmx.settings will probably not work as expected.
While developing you will probably prefer to swap out
argus.site.settings.backend with argus.site.settings.dev, as the former
is almost production-ready while the latter is tuned for development and
depends on the optional dependencies you can install via pip install argus-server[dev].
The argus.site.utils.update_settings function will add or change the settings
See argus_htmx.appconfig._app_settings for what is being set. The
management command printsettings (which depends on the app
django-extensions, a dev-dependency) will print out the complete
settings used.
If you add more pages and endpoints you will have to write your own root urls.py and set ROOT_URLCONF appropriately.
If you have some other apps you want installed and configured, you could either
add the necessary settings to your localsettings.py or use the extra-apps
machinery. The later is especially useful during the development phase when you
haven't settled on which apps to use yet.
With extra-apps machinery
You make a JSON-file which is read into your settings via one of two
environment variables.
In order to add apps and settings that *extend* ``argus-server`` and this
``app`` you use the environment variable ``ARGUS_EXTRA_APPS``::
export ARGUS_EXTRA_APPS=`cat extra.json`
If you want to *override* existing apps the environment variable to use is
``ARGUS_OVERRIDING_APPS``::
export ARGUS_OVERRIDING_APPS=`cat overriding.json`
Have a look at the contents of ``argus_htmx.appconfig._app_settings`` for an
example of what you can set this way.
You can merge your urlpatterns with the apps' urlpatterns via the
``argus.site.utils.get_urlpatterns`` function, see ``argus.htmx.urls`` for an
example.
Optional authentication backend settings
----------------------------------------
If using ``django.contrib.auth.backends.RemoteUserBackend`` (which depends on
the middleware ``django.contrib.auth.middleware.RemoteUserMiddleware``) there's
an optional setting ``ARGUS_REMOTE_USER_METHOD_NAME`` to choose what to show on
the button.
If using ``social_core.backends.open_id_connect.OpenIdConnectAuth`` there's an
optional setting ``ARGUS_OIDC_METHOD_NAME`` to choose what to show on the
button.
Both can be set via environment variables.
Update
======
On every new version, reinstall the dependencies since there might be new ones.
Themes and styling
==================
To try out daisyUI themes use the context processor
``argus_htmx.context_processor.theme_via_session`` instead of
``argus_htmx.context_processor.theme_via_GET``.
Default included themes are: `light`, `dark` and `argus`.
This project supports Tailwind CSS utility classes and daisyUI components for styling.
Below is an overview of the stack, installation and build instructions, and configuration details for themes and styles.
Overview
--------
* Tailwind CSS: A utility-first CSS framework for rapidly building custom user interfaces.
* daisyUI: A component library for Tailwind CSS that provides a set of ready-to-use components as well as color themes.
Installation and build instructions
-----------------------------------
Recommended but open for tweaks and adaptations steps:
1. Get Tailwind standalone CLI bundled with daisyUI from
https://github.com/dobicinaitis/tailwind-cli-extra
Most linux::
$ curl -sL https://github.com/dobicinaitis/tailwind-cli-extra/releases/latest/download/tailwindcss-extra-linux-x64 -o /tmp/tailwindcss
$ chmod +x /tmp/tailwindcss
For other OSes see
https://github.com/dobicinaitis/tailwind-cli-extra/releases/latest/ and
update the bit after ``download/`` accordingly.
Optionally you can compile tailwind+daisyUI standalone cli bundle yourself as described here:
https://github.com/tailwindlabs/tailwindcss/discussions/12294#discussioncomment-8268378.
2. (Linux/OsX) Move the tailwindcss file to your $PATH, for instance to ``~/bin/`` or ``.local/bin``.
3. Go to the repo directory (parent of ``src/``)
4. Build main stylesheet file using ``tailwindcss`` executable from step 1 and
pointing to the included config file:
Manually::
tailwindcss -c src/argus_htmx/tailwindtheme/tailwind.config.js -i src/argus_htmx/tailwindtheme/styles.css --output src/argus_htmx/static/styles.css
Running with the ``--watch`` flag for automatic update on change seems
error-prone so we've made it very easy to run the command, with ``make`` or ``tox``::
make tailwind
tox -e tailwind
Either will rebuild the styles for you.
Customization
-------------
How to customize the look:
* Override Argus' Tailwind CSS theme defaults and/or choose which daisyUI
color themes to include. You can do so by updating the default
``TAILWIND_THEME_OVERRIDE`` and ``DAISYUI_THEMES`` values respectively
before running a ``tailwind_config`` management command:
Via environment variables, for example::
TAILWIND_THEME_OVERRIDE = '
{
"borderWidth": {
"DEFAULT": "1px"
},
"extend": {
"borderRadius": {
"4xl": "2rem"
}
}
}
'
DAISYUI_THEMES = '
[
"light",
"dark",
"cyberpunk",
"dim",
"autumn",
{ "mytheme": {
"primary": "#009eb6",
"primary-content": "#00090c",
"secondary": "#00ac00",
"secondary-content": "#000b00",
"accent": "#ff0000",
"accent-content": "#160000",
"neutral": "#262c0e",
"neutral-content": "#cfd1ca",
"base-100": "#292129",
"base-200": "#221b22",
"base-300": "#1c161c",
"base-content": "#d0cdd0",
"info": "#00feff",
"info-content": "#001616",
"success": "#b1ea50",
"success-content": "#0c1302",
"warning": "#d86d00",
"warning-content": "#110400",
"error": "#ff6280",
"error-content": "#160306"
}
}
]
'
Or by providing corresponding values in your local settings that star-imports from an `argus-server`_ settings file::
TAILWIND_THEME_OVERRIDE = {...}
DAISYUI_THEMES = [...]
Some links that may be relevant for the customization values mentioned above:
* `daisyUI themes`_
* `list of daisyUI color names`_
* `Tailwind CSS theme customization`_
* Override the default main stylesheet path by providing a ``path_to_stylesheet`` value in a template ``context``.
* Include additional styles/stylesheets using the ``head`` block in your templates.
* Generate a Tailwind config file by running the ``tailwind_config`` management
command. By default the generated file will be based on
``src/argus_htmx/tailwindtheme/tailwind.config.template.js`` and expected
values will be injected with reasonable defaults.
UI Settings
===========
Incident table column customization
-----------------------------------
You can customize which columns are shown in the incidents listing table by overriding the
``INCIDENT_TABLE_COLUMNS`` setting. This setting takes a list of ``str`` or
``argus_htmx.incidents.customization.IncidentTableColumn`` instances. when given a ``str``, this
key must be available in the ``argus_htmx.incidents.customization.BUILTIN_COLUMNS`` dictionary. For
example::
from argus_htmx.incidents.customization import BUILTIN_COLUMNS, IncidentTableColumn
INCIDENT_TABLE_COLUMNS = [
"id",
"start_time",
BUILTIN_COLUMNS["description"], # equivalent to just "description"
IncidentTableColumn( # a new column definition
name="name",
label="Custom"
cell_template="/path/to/template.html"
context={
"additional": "value"
}
),
]
For inbuilt support for other types of columns see the howtos in `the local docs <docs/howtos/>`_.

Custom widget
-------------
Argus supports showing an extra widget next to the menubar in the incidents listing. This box can
take the width of 1/3 of the window. You can add the widget by creating a context processor that
injects an ``incidents_extra_widget`` variable that points to an html template::
def extra_widget(request):
return {
"incidents_extra_widget": "path/to/_extra_widget.html",
}
*note* Don't forget to include the context processor in your settings
You could then create ``path/to/_extra_widget.html`` as following::
<div id="service-status" class="border border-primary rounded-2xl h-full p-2">
My custom widget
</div>
Page size
---------
By default, incidents are shown with a page size of ``10`` (ie. 10 rows at a time), and the user can
select a different page size from ``[10, 20, 50, 100]``. It possible to override these settings by
setting the ``ARGUS_INCIDENTS_DEFAULT_PAGE_SIZE`` and ``ARGUS_INCIDENTS_PAGE_SIZES`` setting
respectively.
