1.在urls.py 文件里面

#  课程评论
url(r'^comments/(?P<course_id>\d+)/$',CommentView.as_view(),name='course_comments'),
# 添加课程评论
url(r'^add_comment/$',AddCommentView.as_view(),name='add_comment'),



2.在 views.py文件里面

# 课程评论
class CommentView(LoginRequiredMixin,View):
    def get(self,request,course_id):
        courses = Courses.objects.get(id=int(course_id))
        all_resources = CourseResource.objects.filter(course=courses)
        all_comment = CourseComments.objects.all()
        content = {
            'courses':courses,
            'course_resources': all_resources,
            'all_comment':all_comment,
        }
        return render(request,'course-comment.html',content)


# 用户添加课程评论
class AddCommentView(View):
    def post(self,request):
        if not request.user.is_authenticated():
            # 判断用户是否登陆
            content = {
                'status':'fail',
                'msg':'用户未登录',
            }
            return HttpResponse(content, content_type='application/json')
        course_id = request.POST.get('course_id',0)
        comments = request.POST.get('comments','')
        if course_id > 0 and comments:
            course_comments = CourseComments()
            course = Courses.objects.get(id=int(course_id))
            course_comments.course = course
            course_comments.comments = comments
            course_comments.user = request.user
            course_comments.save()
            content = {
                'status': 'success',
                'msg': '评论成功',
            }
            return HttpResponse(content, content_type='application/json')
        else:
            content = {
                'status': 'fail',
                'msg': '评论失败',
            }
            return HttpResponse(content, content_type='application/json')


3.在HTML里面：

    <script type="text/javascript">
    //添加评论
    $('#js-pl-submit').on('click', function(){
        var comments = $("#js-pl-textarea").val()
        if(comments == ""){
            alert("评论不能为空")
            return
        }
        $.ajax({
            cache: false,
            type: "POST",
            url:"{% url 'course:add_comment' %}",
            data:{'course_id':{{ courses.id }}, 'comments':comments},
            async: true,
            beforeSend:function(xhr, settings){
                xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}");
            },
            success: function(data) {
                if(data.status == 'fail'){
                    if(data.msg == '用户未登录'){
                        window.location.href="/login/";
                    }else{
                        alert(data.msg)
                    }

                }else if(data.status == 'success'){
                    window.location.reload();//刷新当前页面.
                }
            },
        });
    });

</script>

{% for course_resource in course_resources %}
    <li>
        <span><i
                class="aui-iconfont aui-icon-file"></i>&nbsp;&nbsp;{{ course_resource.name }}</span>
        <a href="{{ MEDIA_URL }}{{ course_resource.download }}" class="downcode"
           target="_blank" download="" data-id="274" title="">下载</a>
    </li>
{% endfor %}
