# Query string fields

Tables pass data via the query string to indicate ordering and pagination preferences.

The names of the query string variables are configurable via the options:

- `order_by_field` – default: `'sort'`

- `page_field` – default: `"page"`

- `per_page_field` – default: `"per_page"`, note: this field currently is not used by `{% render_table %}`

Each of these can be specified in three places:

- `Table.Meta.foo`

- `Table(..., foo=...)`

- `Table(...).foo = ...`

If you are using multiple tables on a single page, you will want to prefix these fields with a table-specific name, in order to prevent links on one table interfere with those on another table:

    def people_listing(request):
        config = RequestConfig(request)
        table1 = PeopleTable(Person.objects.all(), prefix="1-")  # prefix specified
        table2 = PeopleTable(Person.objects.all(), prefix="2-")  # prefix specified
        config.configure(table1)
        config.configure(table2)

        return render(request, 'people_listing.html', {
            'table1': table1,
            'table2': table2
        })
