Both the calculate winners and delete actions benefit from some kind of
hint.
The "calculate winners" hint informs administrators that results won't
be publicly available unless the "show results" option is enabled.
The delete action was redirecting with an error message when the budget
couldn't be deleted; IMHO it's better to disable it and inform
administrators why it's disabled. Alternatively we could remove the
button completely; however, users might be looking for a way to delete a
budget and wouldn't find any hint about it.
We're now removing the "Delete" action from the budgets index table,
since most of the time it isn't possible to delete a budget and so the
action takes up space and we get little gain in return. We could keep
the "Delete" icon just for budgets which can be deleted; however, the
alignment of the table rows would suffer, making it harder to find the
intended action.
Having links in the middle of a form distracts users from the task of
filling in the form, and following a link before submitting the form
will mean whatever has been filled in is lost.
And the budgets form is already very long and hard to fill in. Having
the phases table in the middle of it made it even harder. And, since
we're planning to add the option to manage groups and headings from the
same page, it's better to have a dedicated page for the form.
Since we aren't very consistent in the styles for submit buttons in the
admin section, it was possible to accidentally press the "Calculate
Winner Investments" link after filling in the form. This wouldn't submit
the form and so the changes wouldn't be saved.
It's also a bit confusing for users. After filling in a form, users
expect a submit button. When finding two buttons, they've got to stop to
think which one is the one they've got to press.
Furthermore, the "Calculate Winner Investments" link would work better
as a button instead of a link, for the reasons mentioned in commit
5311daadf. Since HTML forms can't be nested, that would mean treating
this button in a different way than the rest of the buttons in the
application.
Moving the link before the form solves the issue.
Since now we've got the budget actions before the budget form, we're
grouping these actions together with the "Preview" action. We're not
adding the "Publish budget" button as well to this group because it's
got an associated message.
