我正在尝试通过python-docx和 django 创建一个 docx 文件。

example-makedocument.py直接使用 python运行示例脚本 ( ) 即可。又名“工作副本”。它按预期生成示例 docx 文件。

然后我所做的是尝试将该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。你会看到我预先做了一些小的修改，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：

  • 确保文件夹/文件结构与工作副本相同（它需要其子文件夹才能正常工作）
  • 我已经尝试将 docx.py 硬编码template_dir到保存文件夹/文件的位置（我已经检查这些结果是否指向与工作副本相同的最终路径）
  • 我已从示例中删除了图像，但会导致错误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？任何人都可以帮忙吗？

此处提供完整的 python-docx 代码。

我的观点：

#from docx import *

    # Save our document
    savedocx(document, coreprops, appprops, contenttypes, websettings,
             wordrelationships, 'Welcome to the Python docx module.docx')

更新。我在下面找到的解决方案的详细信息。

docx.py 代码假设路径与原来不同。这导致 image1.png 文件“丢失”。完成以下步骤为我解决了这个问题。

  1. 编辑 docx.py 文件并添加一个变量：

    docx_dir = '/path/to/docx/文件夹'

  2. 编辑以下行（docx.py）以使用上述变量（显示的大约行号，与原始来源略有不同）

    1. shutil.copyfile（加入（docx_dir，picname），加入（media_dir，picname））
    2. 像素宽度，像素高度 = Image.open(join(docx_dir, picname)).size[0:2]

  3. 以上摆脱了路径问题。但现在我面临着错误local variable 'contenttypes' referenced before assignment。我发现错误不是通过与路径有关的任何事情解决的，而是通过重复名称解决的（我不完全理解为什么仍然如此）。

注意：下面的代码位于我的视图中，或者..如果与原始源相比，它在example-makedocument.py

前：

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')

image1.png必须在正在运行的 Python 程序的当前目录中，或者作为到正在运行的程序的当前目录的相对路径给出，或者可移植性较差，但可能更容易工作，它可以作为绝对路径给出。

特别是，我认为您可能会发现这篇文章中给出的答案最有帮助：Python 在使用 WSGI 和 Apache 运行时的工作目录（用于动态计算image.png.

自上面编写的代码以来，python-docx 模块发生了一些变化。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))
