Reportlab , How to change page orientation?

问题

I am creating pdf file that containing many pages. I want first page to be portrait and rest of the pages will be landscape. I tried,

story.append(NextPageTemplate('landscape')) refererence

But I got,

ValueError: can't find template('landscape') handle_nextPageTemplate args=('landscape',)

I just figured out.

doc = BaseDocTemplate("mypdf.pdf", pagesize=A4, rightMargin=25, leftMargin=25, topMargin=25, bottomMargin=25)
portrait_frame = Frame(doc.leftMargin, doc.bottomMargin, doc.width, doc.height, id='portrait_frame ')
landscape_frame = Frame(doc.leftMargin, doc.bottomMargin, doc.height, doc.width, id='landscape_frame ')

story= []
story.append(<first-page-content>)
story.append(NextPageTemplate('landscape'))
story.append(PageBreak())
story.append(<second-page-content>)

doc.addPageTemplates([PageTemplate(id='portrait',frames=portrait_frame),
                      PageTemplate(id='landscape',frames=landscape_frame, pagesize=landscape(A4)),
                      ])
doc.build(story)
