14639	admin.site.register() does not check if the model is abstract (gives weird error)	Diederik van der Boor	nobody	"When an abstract model is registered with `admin.site.register()` it produces the following error later on:

{{{
type object '...' has no attribute '_default_manager'
}}}

This error does not make much sense unless you're already have more intimate knowledge of the framework. [[br]]
To ease the learning curve of new developers, I think it would make sense to check whether the model is abstract or not."		closed	contrib.admin	dev		fixed	error-messages		Accepted	1	0	1	0	0	0
