To allow duplicate values, use the all=True argument. union(), intersection(), and difference() return model instances of the type of the first QuerySet even if the arguments are QuerySets of other models. Passing different models works as long as the SELECT list is the same in all ...

The additional stipulation on constructors is, not surprisingly, that all constructors must create a set that contains no duplicate elements (as defined above). Note: Great care must be exercised if mutable objects are used as set elements. The behavior of a set is not specified if the valu...
this set if the set contains no elemente2such that(e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returnsfalse. In combination with the restriction on constructors, this ensures that sets never contain duplicate ...
