如何知道 python-docx 中的新段落何时导致新页面

我必须使用动态创建Word文档python-docx。我通过动态添加表行来实现这一点，并且无法知道页面上适合多少条记录，因为这取决于特定的数据。

我需要知道添加到文档（表行或段落）的新元素何时会导致新页面，因此我可以根据每个页面包含的信息在数据库中记录一些数据。

这是生成word文档的代码python-docx:

def get_invoice_word_report(self, request, invoices_controllers):
    import unicodedata
    from django.core.files import File
    from docx import Document
    from docx.shared import Inches, Pt
    from docx.enum.text import WD_ALIGN_PARAGRAPH, WD_BREAK
    from docx.enum.table import WD_ALIGN_VERTICAL
    from docx.enum.table import WD_TABLE_ALIGNMENT

    document = Document()

    section = document.sections[-1]
    section.left_margin = Inches(0.5)
    section.right_margin = Inches(0.5)

    style = document.styles['Normal']
    font = style.font
    font.name ='Arial'
    font.size = Pt(8)

    i = 0
    for invoices_controller in invoices_controllers:
        context = invoices_controller.get_context()
        if i > 0:
            run.add_break(WD_BREAK.PAGE)
            if i == len(invoices_controllers) - 1:
                last = context['invoices']['invoice_number']
        else:
            first = context['invoices']['invoice_number']

        document.add_paragraph("Invoice".format(context['invoices']['invoice_number'])).alignment = WD_ALIGN_PARAGRAPH.RIGHT
        document.add_paragraph("Folio {}".format(context['invoices']['invoice_number'])).alignment = WD_ALIGN_PARAGRAPH.RIGHT
        document.add_paragraph(context['invoices']['agency']['company']['name'])
        document.add_paragraph(context['invoices']['agency']['company']['address'])
        date = context['invoices']['period_end_date'].split('-')
        document.add_paragraph("{}      {}      {}".format(date[2], date[1], date[0])).alignment = WD_ALIGN_PARAGRAPH.RIGHT
        document.add_paragraph(context['invoices']['line'])
        document.add_paragraph(context['invoices']['text'])

        table = document.add_table(rows=1, cols=4)
        hdr_cells = table.rows[0].cells

        hdr_cells[0].width = Inches(0.1)
        hdr_cells[1].width = Inches(10)
        hdr_cells[2].width = Inches(1)
        hdr_cells[3].width = Inches(1)

        for entry in context['invoices']['entries']:
            row_cells = table.add_row().cells
            row_cells[0].text = str(entry['amount'])
            row_cells[1].text = entry['line']
            row_cells[2].text = entry['unit_price_label']
            row_cells[2].paragraphs[0].alignment= WD_ALIGN_PARAGRAPH.RIGHT
            row_cells[3].text = entry['subtotal']
            row_cells[3].paragraphs[0].alignment= WD_ALIGN_PARAGRAPH.RIGHT

            if entry['text']:
                text_cells = table.add_row().cells
                text_cells[1].text = entry['text']

        row_cells = table.add_row().cells
        row_cells[0].text = ''
        row_cells[1].text = ''
        row_cells[2].text = ''
        row_cells[3].text = context['total']
        row_cells[3].paragraphs[0].alignment = WD_ALIGN_PARAGRAPH.RIGHT

        row_cells = table.add_row().cells
        row_cells[0].text = ''
        row_cells[1].text = ''
        row_cells[2].text = ''
        row_cells[3].text = '$0.00'
        row_cells[3].paragraphs[0].alignment = WD_ALIGN_PARAGRAPH.RIGHT

        row_cells = table.add_row().cells
        row_cells[0].text = ''
        row_cells[1].text = ''
        row_cells[2].text = ''
        row_cells[3].text = context['total']
        row_cells[3].paragraphs[0].alignment = WD_ALIGN_PARAGRAPH.RIGHT

        run = document.add_paragraph("Son {}".format(context['total_text'])).add_run()
        i += 1

    current_directory = settings.MEDIA_DIR
    if len(invoices_controllers) > 1:
        file_name = "Invoices {}-{}.docx".format(first, last)
    else:
        file_name = "Invoice {}.docx".format(first)
    document.save(current_directory + file_name)

    return request.get_host()+ settings.MEDIA_URL + file_name

感谢您的帮助。

检测自动（渲染器生成的）分页符python-docx这是不可能的，因为这些中断没有可靠地记录在 XML 中。

您也许能够找到some最后呈现的分页符的指示，具体取决于 .docx 文件的来源。否则，您可能需要使用 Microsoft VBA 界面来访问实时渲染器，该渲染器可能能够为您提供此信息。请注意，分页符位置可能会根据运行 Word 的计算机而发生变化，具体取决于字体规格和打印机驱动程序等因素。

这在其他问题和答案中也出现过。这可能是一个很好的起点：页码 python-docx https://stackoverflow.com/questions/36193159/page-number-python-docx/36194547#36194547

要查看其余内容，请搜索“[python-docx]分页符”，您会发现有很多。方括号部分将结果限制为标有“python-docx”的结果。
