Stories¶

One part of Lino is a system for programming complex printable reports.

One part of that system are “stories”.

A story is a sequence of “chunks” of a bigger document. These chunks can be either an HTML element or a rt.TableRequest instance.

TODO: write more documentation.

Example:

class Foo(dd.Model):
    ...

class FooDetail(dd.FormLayout)

    preview_tab = dd.Panel("""
    second_box
    summary_box
    """, label=_("Preview"))

class Foos(dd.Table):

    @dd.virtualfield(dd.HtmlBox(_("Summary")))
    def summary_box(self, ar):
        return E.div(*ar.story2html(self.summary_story(ar)))

    @dd.virtualfield(dd.HtmlBox(_("Second")))
    def second_box(self, ar):
        return E.div(*ar.story2html(self.second_story(ar)))

    def summary_story(self, ar):

        def render(t):
            sar = ar.spawn(t, master_instance=self)
            if sar.get_total_count():
                yield E.h2(unicode(sar.get_title()))
                yield sar

        yield render(ResultByBudget)
        yield render(DebtsByBudget)
        yield render(BailiffDebtsByBudget)
        yield render(DistByBudget)
