When params[:budget_investment][:valuation_tag_list] was not present,
which is the case when updating an investment using the "mark as visible
to valuators" checkbox, we were removing all valuation tags.
Using a virtual attribute to assign the tags only if the parameter is
present simplifies the code in the controller and avoids the issue.
Using `setseed` and ordering by `RAND()` doesn't always return the same
results because, although the generated random numbers will always be
the same, PostgreSQL doesn't guarantee the order of the rows it will
apply those random numbers to, similar to the way it doesn't guarantee
an order when the `ORDER BY` clause isn't specified.
Using something like `reorder("legislation_proposals.id % #{seed}")`,
like we do in budget investments, is certainly more elegant but it makes
the test checking two users get different results fail sometimes, so
that approach might need some adjustments in order to make the results
more random.
We were showing only the ones being shown in the current page because
we were modifying `@investments` using a method which used
`@investments`, and we were calling that method twice.
There are many possible solutions: using a local variable to store the
result of the `investments` method, modifying `@investments` after
modifying `@investments_map_coordinates`, ... I've used the one which in
my humble opinion is a bit less fragile: not using `@investments` inside
the `investments` method. That way, the `investments` method will always
return the same result.
Note `stub_const("Budgets::InvestmentsController::PER_PAGE", 2)`
wouldn't work because `Budgets::InvestmentsController` isn't loaded when
that line is executed. So we need to load it. Instead of requiring the
file, using `#{Budgets::InvestmentsController}` seems to be an easier
solution.
So under the tab "without valuator" we don't show investments assigned
to a valuator group, just as expected by administrators.
There was a conflict while applying this commit to the CONSUL repo. I've
decided to re-introduce the test which was deleted in commit dddf026a,
which hadn't been deleted in AyuntamientoMadrid@192f1182.
The right syntax would have been:
`after_save :recalculate_heading_winners, if: :incompatible_changed?`
However, since the method `recalculate_heading_winners` already executes
the `if incompatible_changed?` condition, removing it keeps the intended
behaviour.
