我正在尝试通过python-docx和django创建一个docx文件。
直接使用python运行示例脚本(example-makedocument.py
)。 a.k.a“工作副本”。它按预期生成示例docx文件。
我接着尝试将example-makedocument.py
代码移动到Django视图中。这篇文章底部的代码是该视图的代码。你会看到我在前面进行了一些小修改,但通常没有改变。
运行此视图时,我收到有关无法找到图像文件的错误。
[Errno 2] No such file or directory: 'image1.png'
我有:
template_dir
硬编码到保存文件夹/文件的位置(我已经检查过这些结果指向与工作副本相同的最终路径)local variable 'contenttypes' referenced before assignment
我认为它与路径有关,但我不确定为什么/如何?有人可以帮忙吗?

我的观点:
from myapp.libs.docx.docx import *
# ** commented out below line, replaced with above **
#from docx import *
def export_docx(request):
# ** commented out below line **
#if __name__ == '__main__':
# Default set of relationshipships - the minimum components of a document
relationships = relationshiplist()
# Make a new document tree - this is the main part of a Word document
document = newdocument()
# This xpath location is where most interesting content lives
body = document.xpath('/w:document/w:body', namespaces=nsprefixes)[0]
# Append two headings and a paragraph
body.append(heading("Welcome to Python's docx module", 1))
body.append(heading('Make and edit docx in 200 lines of pure Python', 2))
body.append(paragraph('The module was created when I was looking for a '
'Python support for MS Word .doc files on PyPI and Stackoverflow. '

body.append(paragraph('For those of us who prefer something simpler, I '
'made docx.'))
body.append(heading('Making documents', 2))
body.append(paragraph('The docx module has the following features:'))
# Add some bullets

for point in points:
body.append(paragraph(point, style='ListBullet'))
body.append(paragraph('Tables are just lists of lists, like this:'))
# Append a table
tbl_rows = [ ['A1', 'A2', 'A3']

]

# Add an image
relationships, picpara = picture(relationships, 'image1.png',

body.append(picpara)

# Add a pagebreak
body.append(pagebreak(type='page', orient='portrait'))
body.append(heading('Ideas? Questions? Want to contribute?', 2))
body.append(paragraph('Email <python.docx@librelist.com>'))
# Create our properties, contenttypes, and other support files
title = 'Python docx demo'
subject = 'A practical example of making docx from Python'
creator = 'Mike MacCana'
keywords = ['python', 'Office Open XML', 'Word']
coreprops = coreproperties(title=title, subject=subject, creator=creator,
keywords=keywords)
appprops = appproperties()
contenttypes = contenttypes()
websettings = websettings()
wordrelationships = wordrelationships(relationships)
# Save our document
savedocx(document, coreprops, appprops, contenttypes, websettings,
wordrelationships, 'Welcome to the Python docx module.docx')
======
docx.py代码假设路径不同于它。这导致image1.png文件“丢失”。完成以下步骤为我解决了这个问题。
编辑docx.py文件并添加了一个变量:
docx_dir ='/ path / to / docx / folder'
编辑以下行(docx.py)以使用上述变量(显示的大致行数与原始来源略有不同)
以上摆脱了路径问题。但现在我遇到了错误local variable 'contenttypes' referenced before assignment
。我发现错误的解决不是与路径有关,而是重复的名称(我不完全理解为什么这仍然存在)。
注意:下面的代码位于我的视图中或..如果与example-makedocument.py
在:
contenttypes = contenttypes()
websettings = websettings()
wordrelationships = wordrelationships(relationships)
后:
contentt = contenttypes()
webs = websettings()
wordr = wordrelationships(relationships)
# Save our document
savedocx(document, coreprops, appprops, contentt, webs,
wordr, 'Welcome to the Python docx module.docx')

必须位于正在运行的Python程序的当前目录中,或者作为正在运行的程序的当前目录的相对路径,或者不太便于携带,但可能更容易上班,它可以是以绝对路径给出。
特别是,我认为你可能会发现这篇文章中给出的答案最有帮助:Python's working directory when running with WSGI and Apache(用于动态计算image.png
的绝对路径。

自上面编写的代码以来,python-docx模块已经有所改变。现在,在django中添加图像将是这样的:
from docx import *
from docx.shared import Inches
document = Document()
document.add_picture((r'%s/static/images/my-header.png' % (settings.PROJECT_PATH)), width=Inches(4))
