python - 如何将函数结果添加到 Django 中的 标签

Question

我正在尝试将函数的结果打印到 <p> 中单击同一 HTML 页面上的按钮后即可标记。我也在 Django Web 应用程序中工作。

这是我的功能:

def Question_Init():

Beginning_Question_Prompts = ("Who","Whom","What","Where","When","Why","Which",
    "Whose","How","Was","Were","Did","Do","Does")
Ending_Question_Prompts = ("?",":","...")
questions = []

text1 = open('/Users/joshuablew/Documents/myCorpus/version1.txt').read()

textList = sent_tokenize(text1)

for sentence in textList:
    if sentence.startswith(Beginning_Question_Prompts):
        questions.append(sentence)

    if sentence.endswith(Ending_Question_Prompts):
        questions.append(sentence)

return questions

我想将此函数的结果(即“问题”列表)添加到此处的段落标记中:

<div class="content">
  <button type="button" class="btn btn-primary">Show Questions</button>
  <p>#Where I want the results of Question_Init() to go</p>
</div>

我必须对按钮属性做什么才能发生这种情况？这应该用 JavaScript 来完成吗？或者可以通过其他方式完成吗？

感谢您的帮助。

我认为您可能会发现编写自己的自定义模板标记很有用。您可以通过示例找到更多信息 here

首先，您应该创建存储自定义标签的位置。您应该将包 templatetags 添加到您的应用程序目录中(带有 __init__.py 的目录)然后为标签创建文件，例如csv_content.py

在该文件中定义您的标签:

from django import template

register = template.Library()

@register.simple_tag
def csv_content():
    html_result='' 
    #define path to your csv file
    csv_path = 'test.csv'

    text1 = open(csv_path).read()

    textList = sent_tokenize(text1)

    for sentence in textList:
      #you probably want some styling here
      html_result += '<p>{}</p>'.format(sentence)

    return html_result

然后在您的模板中，您可以使用您的标签，例如 {% csv_content %}
