Question

我尝试按照https://groups.google.com/forum/#!topic/python-pptx/nrUkiQQHyZo中的说明关注示例，但结果却出现了错误'Slide' object has no attribute 'rels'。

我尝试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，是否有更简单的方法来实现这一目标？

AttributeError: 'Slide' object has no attribute 'rels'

Answer 1

根据@scanny的评论，将s3更改为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()

Answer 2

将已经在此线程中发布的所有信息汇总在一起，这是一个最小的示例：

# 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' )

希望这会有所帮助！
