Description
On the following example, tab completion suggests sum
, which is not an attribute of
R
.

This issue happens in both the notebook and command line.

This should be fixed once #9138 will be implemented.

Indeed, it is a duplicate.
With the patches from #9944 and #9138, one obtains:
sage: R = QQ['t'] sage: R.sum <bound method PolynomialRing_field_with_category.sum of Univariate Polynomial Ring in t over Rational Field> sage: R.summ R.summation R.summation_from_element_class_add sage: R.summation_from_element_class_add <bound method PolynomialRing_field_with_category.summation of Univariate Polynomial Ring in t over Rational Field>
I learnt: In that case, one should give a ticket a positive review and choose the milestone "duplicate", so that the release manager may close it.

PS: #9138 needs review (hint...)

Note: See
TracTickets for help on using
tickets.
Notice also that other longer summation_from_element_class_add:
So, this suggests that this bug has something to do with Nicolas's category theory rewrite? I'll post to sage-combinat.
