A simple alerts framework for your Wagtail website
Project description
wagtail_alerts
Simple wagtail alerts and toasts to programatically display or to create via settings inside of the wagtail admin.
Quick start
-
Add 'wagtail_alerts' and it's dependency' to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [ ..., 'wagtail_alerts', 'globlocks', ] -
Run
py ./manage.py collectstatic -
Run
py ./manage.py makemigrations(We did not do this to prevent the wagtail 5/6 migration errors which might occur.) -
Run
py ./manage.py migrate -
Add the template tags and scripts to your
<body>{% load wagtail_alerts_tags %} <link rel="stylesheet" href="{% url 'wagtail_alerts:css' %}"/> <script src="{% static 'wagtail_alerts/js/wagtail_alerts.js' %}"></script> {% wagtail_alerts container_class="fixed fixed-top" %} {% wagtail_alerts alert_type="TOAST" %}
Custom Alert Types/Templates
You can add your own custom alert types by defining them in settings with WAGTAIL_ALERTS_TYPES = [...]
Example settings
# settings.py
WAGTAIL_ALERTS_TYPES = [
("CUSTOM", _("Custom"), "myapp/blocks/my_alert_template.html", "myapp/templatetags/my_custom_list_template.html"),
]
Example list template
We must then provide the HTML template to display the list of alerts.
<!-- myapp/templatetags/my_custom_list_template.html -->
<div class="wagtail-alerts {{ CSS_VARIABLE_PREFIX }}custom-container {{ container_class }}">
<div class="{{ CSS_VARIABLE_PREFIX }}custom-wrapper">
{% for alert in alerts %}
{% include_block alert with index=forloop.counter0 %}
{% endfor %}
</div>
</div>
List Template Context
We provide the following context for your custom alert type list template.
{{ alerts }}
{{ settings }}
{{ container_class }}
{{ CSS_VARIABLE_PREFIX }}
Example Alert Template
Following that we can provide the alert template to render the individual alerts which have alert_type="CUSTOM".
<!-- myapp/blocks/my_alert_template.html -->
<div class="{{CSS_VARIABLE_PREFIX}}custom-alert {{CSS_VARIABLE_PREFIX}}{{self.settings.alert_theme}}" id="alert-{{ index }}" data-duration="{{ self.settings.duration|default:0 }}" data-cookie-key="{{self.cookie_key}}"{% if self.once_per_session %} data-once{%endif%}{% if self.permanent_dismiss %} data-permanent-dismiss{%endif%}>
<!-- Do something with these attributes! We do not implement this for you. -->
<div class="custom-alert-content">
{% if self.title %}
<div class="alert-title">
{{ self.get_title|safe }}:
</div>
{% endif %}
<div class="alert-text">
{{ self.get_body|safe }}
</div>
</div>
<div class="dismissible-wrapper">
{% if self.settings.dismissible %}
<button type="button" class="alert-dismissible" aria-label="{% translate "Close" %}">×</button>
{% endif %}
</div>
</div>
{% endlocalize %}
Alert template context
For the full context of your alert template see blocks.py.
Hooks
Example usage of registering a custom alert from code
We provide hooks to allow you to add your own alerts to the alerts list.
This is useful if you want to add alerts based on some condition in your code.
from wagtail_alerts.alert import Alert
@hooks.register('wagtail_alerts.construct_alerts')
def construct_alerts(request, base_list, settings):
"""
Construct the alerts for the request.
"""
...
if some_condition:
base_list.append(Alert(
title="This is a test alert",
body="This is the test alert body",
alert_theme="primary",
dismissible=True,
duration=5000,
alert_type="TOAST",
))
Example of changing the alert styles
We provide hooks to let you change the styles of the alerts.
This is useful if you want to change the colors of the alerts based on your theme.
from wagtail import hooks
@hooks.register("wagtail_alerts.construct_styles")
def construct_styles(request, styles, settings):
styles.change_color("primary", "#ff0000")
styles.change_theme("dark", "#000000")
styles.PRIMARY.text_color = "#ff0000"
styles.PRIMARY.theme_color = "rgba(0, 0, 0, 0.5)"
