[FEATURE] filter on unrelated model

[Maarten-vd-Sande]

Is your feature request related to a problem? Please describe:

I admit I am doing some unconventional stuff. But I have a Django admin app where I also have some visualzations. These visualzations put together data from multiple sources, and are not in the database itself. It would be nice if on these visualzation pages, I could refer to any one model and have an (ajax) autocompletefilter.

Describe the solution you'd like:

Something along the lines of:

class ExperimentFilter(UnrelatedFieldAjax):
    model = Experiment
    field = "name"


@admin.register(PlateInspectorViz)
class PlateInspectorAdmin(admin.ModelAdmin):
    change_list_template = "dashboard/plot.html"
    list_filter = [
        ExperimentFilter
    ]

Maybe something like this is already possible? But I haven't been able to figure out how to do this.

The filter wouldn't have to actually filter anything, except have nice autocomplete function and change the URL depending on the choice.
