要构建一个基于Django的问答图谱查询应用，你需要遵循以下步骤：

1. 安装必要的依赖项：
2. Django
3. django-csv
4. django-plotly
5. Django-redis
6. pyquery
7. yfinance
8. pytz
9. pandas
10. nltk
11. seaborn
12. matplotlib
13. nltk
14. matplotlib
15. nltk
16. seaborn
17. matplotlib
18. nltk
19. seaborn
20. matplotlib
21. nltk
22. seaborn
23. matplotlib
24. nltk

25. seaborn

26. 安装所需的库： pip install django django-csv django-plotly django-redis pip install pyquery pytz pandas nltk seaborn matplotlib nltk seaborn

27. 创建一个新项目： django-admin startproject knowledge_graphql cd knowledge_graphql

28. 运行Django项目： python manage.py runserver

29. 创建模型和数据： ``` from django.db import models from django.contrib.auth.models import User

class Question(models.Model): title = models.CharField(max_length=100) content = models.TextField() tags = models.ManyToManyField('self', through='Tag') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True)

class Tag(models.Model): name = models.CharField(max_length=100) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True)

class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) answer = models.TextField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) tags = models.ManyToManyField('self', through='Tag') ```

1. 创建视图： ``` from django.shortcuts import render from .models import Question, Answer from .models import Tag

def index(request): questions = Question.objects.all() answers = Answer.objects.all() tags = Tag.objects.all()

   context = {'questions': questions, 'answers': answers, 'tags': tags}
   return render(request, 'knowledge_graphql/index.html', context)

def tag_view(request, tag_name): question = Question.objects.get(id=question_id) tags = question.tags.all() tags = sorted(tags, key=lambda tag: tag.name) answer = Answer.objects.get(id=answer_id) tags = answer.tags.all() tags = sorted(tags, key=lambda tag: tag.name)

   context = {'question': question, 'tags': tags}
   return render(request, 'knowledge_graphql/tag_view.html', context)

```

1. 创建URL配置： ``` from django.urls import path from . import views

urlpatterns = [ path('questions/', views.index, name='index'), path('tags//', views.tag_view, name='tag_view'), ] ```

1. 创建URL路由： ``` from django.contrib import admin from django.urls import path, include

urlpatterns = [ path('admin/', admin.site.urls), path('api/', include('knowledge_graphql.urls')), ] ```

1. 配置Django管理后台： 在settings.py文件中添加以下配置： UWSGI_HOST = '127.0.0.1' UWSGI_PORT = 8080 UWSGI发展规划 = { 'socket_host': '127.0.0.1', 'socket_port': 8080, }

2. 运行Django项目： python manage.py runserver

现在，你已经创建了一个基于Django的问答图谱查询应用。你可以使用它来获取和显示特定问题和标签的答案。你可以通过查询API来获取和显示特定标签的答案。
