基于django的个人博客网站建立（四）

前言

今天主要添加了留言与评论在后台的管理和主页文章的分页显示，文章类别的具体展示以及之前预留链接的补充

主要内容

其实今天的内容和前几天的基本相似，就是个体力活

首先是评论在后台的管理：


@auth
def view_comment(request):
    if request.method == 'GET':
        all_comment = models.Comment.objects.all().order_by('id').reverse()
        return render(request, 'backend/view_comment.html', {'all_comment': all_comment})


{% extends 'backend/base.html' %}

    {% block link %}
        <!-- Bootstrap Markdown -->

    {% endblock %}

   {% block content %}
  <div class="content-wrapper">
    <!-- Content Header (Page header) -->
    <section class="content-header">
      <h1>
        查看评论
      </h1>
      <ol class="breadcrumb">
        <li class="breadcrumb-item"><a href="#">我的博客后台</a></li>
        <li class="breadcrumb-item active">查看评论</li>
      </ol>
    </section>

    <!-- Main content -->
    <section class="content">

      <div class="row">

          <div  class="col-lg-12">
            <div class="box">
               <div class="box-header with-border">
                 <h3 class="box-title">评论列表</h3>
               </div>
               <!-- /.box-header -->
               <div style="height: auto"  class="box-body">
                        <div class="table-responsive">
            <table id="articlelist" class="table table-hover no-wrap dataTable" data-page-size="10" role="grid" aria-describedby="articlelist_info">
               <thead>
                  <tr role="row"><th class="sorting_asc" tabindex="0" aria-controls="articlelist" rowspan="1" colspan="1" aria-sort="ascending" aria-label="No: activate to sort column descending">Id</th>
                            <th class="sorting" tabindex="0" aria-controls="articlelist" rowspan="1" colspan="1" aria-label="Name: activate to sort column ascending">Username</th>
                            <th class="sorting" tabindex="0" aria-controls="employeelist" rowspan="1" colspan="1" aria-label="Name: activate to sort column ascending">content</th>
                            <th class="sorting" tabindex="0" aria-controls="employeelist" rowspan="1" colspan="1" aria-label="Name: activate to sort column ascending">creationTime</th>
                            <th class="sorting" tabindex="0" aria-controls="employeelist" rowspan="1" colspan="1" aria-label="Name: activate to sort column ascending">Email</th>
                            <th class="sorting" tabindex="0" aria-controls="employeelist" rowspan="1" colspan="1" aria-label="Name: activate to sort column ascending">Articletitle</th>
                            <th class="sorting" tabindex="0" aria-controls="articlelist" rowspan="1" colspan="1" aria-label="Action: activate to sort column ascending">Action</th>
                        </tr>
               </thead>
               <tbody>

                    {% for comment in all_comment %}
               <tr role="row" class="odd">
                     <td class="sorting_1">{{ comment.id }}</td>

                     <td>{{ comment.userName }}</td>
                            <td>{{ comment.content }}</td>
                            <td>{{ comment.creationTime }}</td>
                            <td>{{ comment.email }}</td>
                            <td>{{ comment.article.title }}</td>
                     <td>

                                <form style="margin-top: 3px" action="/backend/delete_comment/" method="post">
                                    {% csrf_token %}
                                    <input name="delete_comment_id" style="display: none" type="text" value="{{ comment.id }}">
                                    <button type="submit" class="btn btn-sm btn-danger-outline" data-toggle="tooltip" data-original-title="删除"><i class="ti-trash" aria-hidden="true"></i></button>
                                </form>
                            </td>
                  </tr>
                    {% endfor %}
                  </tbody>

            </table>
                        </div>
                </div>

             </div>

              <!-- /.box -->
          </div>

      </div>

   </section>
   <!-- /.content -->
  </div>


{% endblock %}

{% block script %}
    <script>
        $('#view_comment').addClass('active')

    </script>

{% endblock %}

删除评论：


@auth
def delete_comment(request):
    if request.method == 'POST':
        delete_comment_id = request.POST.get('delete_comment_id')
        models.Comment.objects.filter(id=delete_comment_id).delete()
        return redirect('/backend/view_comment')

然后同样是留言的管理：


@auth
def view_message(request):
    if request.method == 'GET':
        all_message = models.Message.objects.all().order_by('id').reverse()
        return render(request, 'backend/view_message.html', {'all_message': all_message})

@auth
def delete_message(request):
    if request.method == 'POST':
        delete_message_id = request.POST.get('delete_message_id')
        models.Message.objects.filter(id=delete_message_id).delete()
        return redirect('/backend/view_message')

接下来讲主页的分页显示

这里主要用了django的Paginator做了分页管理：


def index(request):
    if request.method == 'GET':

        all_article = models.Article.objects.all().order_by('id').reverse()
        paginator = Paginator(all_article,7)
        page = request.GET.get('page')
        try:
            contacts = paginator.page(page)
        except PageNotAnInteger:

            contacts = paginator.page(1)
        except EmptyPage:

            contacts = paginator.page(paginator.num_pages)

        all_type = models.ArticleType.objects.all()
        return render(request, 'show/index.html',{'all_article':contacts,'all_type':all_type})

页面显示也做了修改

      <!-- ======================== END HEADER AREA HERE ================================= -->
      <!-- =================== START MAIN CONTENT AREA HERE ========================-->
{% block main %}

            <div class="post-pagination text-center" data-aos="fade-up">
             <ul>

      <!-- ======================== END MAIN CONTENT AREA HERE ========================-->

显示为：

def category(request):
    if request.method == 'GET':
        all_type = models.ArticleType.objects.all()
        return render(request, 'show/category.html', {'all_type': all_type})
