How to change django wagtail's admin logo

Question

I am working on a small project and I thought I'd give wagtail a try. I am now wondering how I could change wagtail's admin logo in the sidebar (top left image on the picture bellow).

I could change /static/wagtailadmin/images/wagtail-logo.svg directly but it'd be wrong ;).

Answer 1

Wagtail already provide the solution in the official documentation using django-overextends:

To replace the default logo, create a template file your_app/templates/wagtailadmin/base.html that overrides the block branding_logo as follow:

{% overextends "wagtailadmin/base.html" %}

{% block branding_logo %}
    <img src="{{ STATIC_URL }}images/custom-logo.svg" alt="Custom Project" width="80" />
{% endblock %}

Check Wagtail Custom branding for more details.

Answer 2

The logo is defined here:

https://github.com/torchbox/wagtail/blob/master/wagtail/wagtailadmin/templates/wagtailadmin/base.html#L7

To override it, you'll need an app which contains templates/wagtailadmin/base.html and precedes wagtail in INSTALLED_APPS.

Good luck!
