Should this be `r.field.name` so the error in the example of the ticket is:

    myapp.specialdetail: Accessor for field 'parent' clashes with accessor for field 'SpecialDetail.target'.
    Add a related_name argument to the definition for 'parent'.

instead of:

    myapp.specialdetail: Accessor for field 'parent' clashes with accessor for field 'SpecialDetail.myapp:specialdetail'.
    Add a related_name argument to the definition for 'parent'.
