Python PPTX内部超链接解决方案函数

我尝试按照中讨论的示例进行操作，但最终出现错误“Slide”对象没有属性“rels”

我正在试验的最小代码尝试在第一张幻灯片到第三张幻灯片中构建超链接

import pptx
import pptx.enum
from pptx import Presentation
from pptx.enum.action import PP_ACTION
from pptx.opc.constants import RELATIONSHIP_TYPE as RT

#very minimal Powerpoint template
prs = Presentation("tpl.pptx")

# create 3 slides, each with single text placeholder
s1 = prs.slides.add_slide(prs.slide_layouts[0])
s2 = prs.slides.add_slide(prs.slide_layouts[0])
s3 = prs.slides.add_slide(prs.slide_layouts[0])

# create internal hyperlink
rId = s1.part.relate_to(s3, RT.SLIDE)
r = s1.placeholders[10].text_frame.paragraphs[0].add_run()
r.text = "Link to Slide 3"
rPr = r._r.get_or_add_rPr()

hlinkClick = rPr.add_hlinkClick(rId)
hlinkClick.set('action', 'ppaction://hlinksldjump')

# ERROR WHEN SAVING - Slide' object has no attribute 'rels #
prs.save("Test.pptx")

如何解决错误？或者，有没有更简单的方法来实现这一点

根据@scanny的评论，将s3改为s3.part效果很好

# create internal hyperlink
rId = s1.part.relate_to(s3.part, RT.SLIDE)
r = s1.placeholders[10].text_frame.paragraphs[0].add_run()
r.text = "Link to Slide 3"
rPr = r._r.get_or_add_rPr()

将此线程中已发布的所有信息放在一起，下面是一个简单的示例：

# Workaround for python-pptx lack of internal hyperlink support
from pptx.enum.action import PP_ACTION
from pptx.opc.constants import RELATIONSHIP_TYPE as RT
def Hyperlink( run_object, source_slide, destination_slide ):
    rId = source_slide.part.relate_to(destination_slide.part, RT.SLIDE)
    rPr = run_object._r.get_or_add_rPr()
    hlinkClick = rPr.add_hlinkClick(rId)
    hlinkClick.set('action', 'ppaction://hlinksldjump')

# Example of usage:

from pptx import Presentation

prs = Presentation()
slide = dict()

# Make Slides

title_slide_layout = prs.slide_layouts[0]
slide['title'] = prs.slides.add_slide( title_slide_layout )
title = slide['title'].shapes.title
title.text = 'Presentation with Internal Hyperlinks'

two_content_slide = prs.slide_layouts[3]
slide['table of contents'] = prs.slides.add_slide( two_content_slide )
shapes = slide['table of contents'].shapes
title = shapes.title
title.text = 'Table of contents'

two_content_slide = prs.slide_layouts[3]
slide['slide a'] = prs.slides.add_slide( two_content_slide )
shapes = slide['slide a'].shapes
title = shapes.title
title.text = 'Slide A'

two_content_slide = prs.slide_layouts[3]
slide['slide b'] = prs.slides.add_slide( two_content_slide )
shapes = slide['slide b'].shapes
title = shapes.title
title.text = 'Slide B'

# Populate contents (with hyperlinks)

shapes = slide['table of contents'].shapes
body = shapes.placeholders[1]
tf = body.text_frame
p = tf.add_paragraph()
r = p.add_run()
r.text = 'Slide A'
Hyperlink( r, slide['table of contents'], slide['slide a'] )
p = tf.add_paragraph()
r = p.add_run()
r.text = 'Slide B'
Hyperlink( r, slide['table of contents'], slide['slide b'] )

# Save as .pptx file

prs.save( 'hyperlink_slides.pptx' )

希望这有帮助

请发布完整的堆栈跟踪。通常这意味着幻灯片用作幻灯片部分；这两个人不久前在代码中是分开的。我会尝试将s3改为s3.part，在以rId=开头的行中，看看这是否起作用。
