wagtail

TemplateDoesNotExist error for a simple ModelAdmin example

I've used Wagtail's ModelAdmin on a few other projects with great success, but this is the first time I'm attempting to use it with a model inheriting from Page.

I copied the simple example template and removed the parts that didn't relate to my BlogPageModel.

The link to the ModelAdmin appears as expected, but when I click it, I get TemplateDoesNotExist at /admin/blog/blogpage/.

I don't remember having to set up a template before. Is there a setting I'm missing?

Wagtail: 1.9 / Django: 1.10.5 / Python: 3.5.2

Update: I tried it with a model that inherits from models.Model as well with the same result.

Traceback follows:

Solution

  • I suspect you've missed out adding 'wagtail.contrib.modeladmin' to INSTALLED_APPS.

    If you're using the add-on wagtail-modeladmin package (which is the only option from Wagtail 6.0 onward, as it's no longer part of Wagtail itself), the path to add to INSTALLED_APPS is 'wagtail_modeladmin'.
