Question

When i try to create a new project in Timepiece the project is added to my model as i can see in the backend but the view gives me a TemplateSyntaxError.

it states:

Caught ImproperlyConfigured while rendering: settings.AJAX_LOOKUP_CHANNELS not configured correctly for 'user'

the django docs give me that there is a setting missing in my settings.py. But i don’t know which.

Excuse me if this is very obvious.

My traceback:

Answer 1

It looks like you are using django_ajax_selects project which requires a setting AJAX_LOOKUP_CHANNEL in your main settings.py that maps models to fields. Something like:

AJAX_LOOKUP_CHANNELS = {
    'person'  : {'model':'example.person', 'search_field':'name'}
}

(from it’s docs)
