Question

我正在使用Django tables2。我页面中有n行，我想export only the rows which the user selects。但是我找不到一种使它起作用的方法。官方文档无济于事。

当我选择要导出的行时，然后单击“导出”。 The entire table is exported.

tables.py

class TrackerTable(tables.Table):
    export_formats = ['csv', 'xls', 'xlsx', 'json']
    id = tables.Column()
    id = tables.LinkColumn('posts:tracker_view',args=[A('pk')], empty_values=())
    editable = tables.LinkColumn('posts:modify',args=[A('pk')] , empty_values=(), verbose_name='')
    selection = tables.CheckBoxColumn(accessor=A('pk')t ,empty_values=(), footer='', attrs = { "th__input":{"onclick": "toggle(this)"}}, orderable=False)
    def render_editable(self):
        #return 'Edit'
        return mark_safe('<center><p style="color:blue;">&#9997;</p></center>')



    class Meta:
        model = models.Post
        template_name = 'django_tables2/semantic.html'
        sequence = ('selection','editable','id','...')
        attrs = {'tbody': {'id': 'myTable'}}

views.py

    table = TrackerTable(Post.objects.all(), order_by="-id")
    RequestConfig(request).configure(table)
    export_format = request.GET.get('_export', None)
    if TableExport.is_valid_format(export_format):
        exporter = TableExport(export_format, table, exclude_columns=('editable','selection'))
        return exporter.response('table.{}'.format(export_format))

    return render(request, 'posts/tracker_list.html', {'table': table})```

仅导出Django-Tables2中的选定行
