Django前端搜索

为用户显示标题中含有被搜索关键词的全部文章。整个搜索的过程如下：
1、用户在搜素框中输入搜索关键词，假设为 “django”，然后用户点击了搜索按钮提交其输入的结果到服务器
2、服务器接收到用户输入的搜索关键词 “django” 后去数据库查找文章标题中含有该关键词的全部文章
3、服务器将查询结果返回给用户

可以使用此示例在视图中实现自己的搜索引擎

def search(request):

keywords=''

if request.method=='POST': # form was submitted

    keywords = request.POST.get("keywords", "") # <input type="text" name="keywords">
    all_queries = None
    search_fields = ('title','content','resume') # change accordingly
    for keyword in keywords.split(' '): # keywords are splitted into words (eg: john science library)
        keyword_query = None
        for field in search_fields:
            each_query = Q(**{field + '__icontains': keyword})
            if not keyword_query:
                keyword_query = each_query
            else:
                keyword_query = keyword_query | each_query
                if not all_queries:
                    all_queries = keyword_query
                else:
                    all_queries = all_queries & keyword_query

    articles = Article.objects.filter(all_queries).distinct()
    context = {'articles':articles}
    return render(request, 'search.html', context)

else: # no data submitted

    context = {}
    return render(request, 'index.html', context) 

您只需要更改以下内容：

1 - html中使用的name属性

keywords = request.POST.get("keywords", "")
2 - 模型类的名称

3 - 该模型的搜索字段
