Django前后端分离开发-新闻管理系统(六)

一、新闻搜索功能

# 搜索
def search(request):
    strquery = request.GET.get('query')
    page = int(request.GET.get('page', 1))
    data = {
        "search": strquery,
        "page": page,
        "ordering": '-id',
    }
    article_data = getdata(articles_url, data)
    article_list = article_data["results"]
    # 总记录数
    count = article_data["count"]
    # 下一页
    next = article_data["next"]
    nextpage = page + 1
    # 上一页
    previous = article_data["previous"]
    previouspage = page - 1
    # 总页数
    num_pages = int(count / PAGESIZE)
    curr_url = request.get_full_path()
    nPos = curr_url.find('&page')
    if nPos > 0:
        curr_url = request.get_full_path()[0:nPos]
    else:
       curr_url = request.get_full_path()

    return render(request, 'searchlist.html', locals())

根据传入的字符串查询，并对查询结果分页传给searchlist.html

{% extends 'base.html' %}

{% load staticfiles %}
{% block left_content %}
    

        

        {% if  article_list %}
          {% for article in article_list %}
              

                

                    
推荐
                    
                    
                    

                        

                            
{{ article.id }}-{{ article.title }}
                        
                        
{{ article.content|striptags|safe|slice:"80" }}
                        

                            {{ article.author.username }}
                            

                               {{ article.publish_date |date:"Y-m-d H:i:s"}}
                               {{ article.item.title }} 

                            
                        
                    
                
            
           {% endfor %}
        {% else %}
         

        {% endif %}
         

    
    {% include 'page.html' %}

{% endblock %}

page.html

 {% if num_pages > 1 %}
     

            
           {% if previous %}
                  上一页
           {% endif %}

          
                  Page {{ page }} of {{  num_pages }}.
          
           
          {% if next %}
                下一页
                
          {% endif %}
          
     
 {% endif %}

二、文章详情页

# 文章详情页
def article(request):
    id = request.GET.get('id')
    articles_url = 'http://127.0.0.1:8005/articleList/'
    # 构造url http://127.0.0.1:8000/article/id/
    articles_url = urljoin(articles_url, id)
    article = getdata(articles_url)
    return render(request, 'article.html', locals())

article.html

{% extends 'base.html' %}
{% load staticfiles %}

{% block left_content %}
   

    

        
{{ article.title }}
        

          {{ article.author.username }}
          {{ article.item.title }}
          浏览数{{ article.read_num }}
            
            收藏
          
          {{ article.publish_date | date:'Y-m-d' }}
        
    
        

         
 {{ article.content| safe }}
        
        
            {% for tag in article.tags %}
            {{ tag.name }}  
            {% endfor %}
        
   

{% endblock %}

三、按标签查询对应的文章列表

def tag(request):
    tagid = request.GET.get('tagid')
    page = int(request.GET.get('page', 1))
    data = {
        "tags": tagid,
        "page": page,
        "ordering": '-id',
    }
    article_data = getdata(articles_url, data)
    article_list = article_data["results"]
    # 总记录数
    count = article_data["count"]
    # 下一页
    next = article_data["next"]
    nextpage = page + 1
    # 上一页
    previous = article_data["previous"]
    previouspage = page - 1
    # 总页数
    num_pages = int(count / PAGESIZE)
    curr_url = request.get_full_path()
    nPos = curr_url.find('&page')
    if nPos > 0:
        curr_url = request.get_full_path()[0:nPos]
    else:
        curr_url = request.get_full_path()
    return render(request, 'tag.html', locals())

tag.html

{% extends 'base.html' %}
{% load staticfiles %}
{% block left_content %}
     

      
标签{{ request.GET.tag }}
      {% for article in article_list %}
      

        

          
{{ article.title }}
          
{{ article.desc }}
          

              {% for tag in article.tag.all %}
                  {{ tag.name }} 
              {% endfor %}
              {{ article.date_publish | date:'Y-m-d' }}
        
      
      {% endfor %}
    

{% endblock %}

四、分类页

def category(request):
    categoryid = request.GET.get('cid')
    print(categoryid)
    currcategoryid = request.GET.get('cid')
    print(currcategoryid)
    page = int(request.GET.get('page', 1))
    # 取二级栏目
    data = {
    "categorys": categoryid,
    }
    ul = "http://127.0.0.1:8005/categoryitems/"
    print(ul)
    print(data)
    items_list = getdata(ul, data)
    print(99, items_list)
    # for i in items_li:
    #     items_list = (i["items"])
    # 取新闻
    data = {
        "item__categorys": categoryid,
        "page": page,
        "ordering": '-id',
    }
    article_data = getdata(articles_url, data)

    article_list = article_data["results"]

    # 总记录数
    count = article_data["count"]
    # 下一页
    next = article_data["next"]
    nextpage = page + 1
    # 上一页
    previous = article_data["previous"]
    previouspage = page - 1
    # 总页数
    num_pages = int(count / PAGESIZE)
    curr_url = request.get_full_path()
    nPos = curr_url.find('&page')
    if nPos > 0:
        curr_url = request.get_full_path()[0:nPos]
    else:
        curr_url = request.get_full_path()
    return render(request, 'category.html', locals())

五、根据二级栏目类型取新闻列表

def item(request):
    categoryid = request.GET.get('cid')
    itemid = request.GET.get('itemid')
    page = int(request.GET.get('page', 1))
    # 取二级栏目
    data = {
        "categorys": categoryid,
    }
    items_data = getdata(items_url, data)
    items_list = items_data
    # 取新闻
    data = {
        "item": itemid,
        "page": page,
        "ordering": '-id',
    }
    article_data = getdata(articles_url, data)
    article_list = article_data["results"]

    # 总记录数
    count = article_data["count"]
    # 下一页
    next = article_data["next"]
    nextpage = page + 1
    # 上一页
    previous = article_data["previous"]
    previouspage = page - 1
    # 总页数
    num_pages = int(count / PAGESIZE)
    curr_url = request.get_full_path()
    nPos = curr_url.find('&page')
    if nPos > 0:
        curr_url = request.get_full_path()[0:nPos]
    else:
        curr_url = request.get_full_path()
    return render(request, 'category.html', locals())

category.html

{% extends 'base.html' %}
{% load staticfiles %}
{% block left_content %}
    {% if  items_list %}
        

        {% for item in items_list %}
                 

                     
                         {{ item.title }}
                       
                 
        {% endfor %}
        
    {% endif %}
    

        

         {% if  article_list %}
            {% for article in article_list %}
              

                

                    
推荐
                    

                    
                    

                        

                            
{{ article.id }}-{{ article.title }}
                        
                        
{{ article.content|striptags|safe|slice:"80" }}
                        

                            {{ article.author.username }}
                            

                                {{ article.publish_date }}
                                 {{ article.item.title }} 
                            
                        
                      
                
            

           {% endfor %}
         {% else %}
         

        {% endif %}

         
    {% include 'page.html' %}
    

{% endblock %}

最后添加urls.py文件中添加路径

path('item/', item, name='item'),
path('tag/', tag, name='tag'),
