django - 为什么Django pagenotAnTntger 除了生成？

问题描述

我有服务器错误！

我想制作projectBoard主页 当我点击作品的标题时，我想显示作品的详细信息。

但是 pageNotAnInteger 除了生成

在 projectMain.html 中

<a href="{% url 'fileDetail' file_title=post.file_title %}"> {{ post.file_title }} </a>

通过这句话，我想深入到写作的细节。

但是，我不能。

我以为这些过程

  1. 点击文章的标题。

  2. 在 projectMain.html 中，代码 , <a href="{% url 'fileDetail' file_title=post.file_title %}"> {{ post.file_title }} </a>被执行。

  3. 然后， ' urlpattern url(r'^project/(?P<file_title>.+)/$', views.fileDetail, name='fileDetail'),' 被执行

  4. 在views.py中，函数fileDetail()被执行，执行projectDetail.html会被渲染

但导致 pageNotAnIntegerError

我该如何解决？

项目Main.html

{% extends 'Project/projectBase.html' %}

{% block content %}


<div class="container">

  <!-- Page Heading/Breadcrumbs -->
  <div class="row">

视图.py

def mainProject(request, project_name):
    check = auth_test(request)
    posts = ProjectFiles.objects.filter(project_name = project_name)
    posts = posts.order_by('-origin_date')
    paginator = Paginator(posts, 6)
    page = request.GET.get('page')

    try:
        posts = paginator.page(page)
    except PageNotAnInteger:
         # If page is not an integer, deliver first page.
        posts = paginator.page(1)
        print("PageNotAnInteger")
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        posts = paginator.page(paginator.num_pages)

    max_index = len(paginator.page_range)
    return render(request, 'Project/projectMain.html', {
            'project_name': project_name,
            'posts': posts,
            #'check ' : check,
            'max_index': max_index,})




def fileDetail(request, file_title):
    check = auth_test(request)
    post = get_object_or_404(ProjectFiles, project_name=check['project_name'], file_title=file_title)
    project_name = post.project_name
    return render(request, 'Project/projectDetail.html', {'post': post, 'check': check, 
                                                          'file_title': file_title, 
                                                          'project_name': project_name,})

我认为它可能是从制作文件中生成的，我添加了文件制作代码

项目编辑.html

{% extends 'Project/projectBase.html' %}

{% block content %}
<div class="container">

      <!-- Page Heading/Breadcrumbs -->
      <h1 class="mt-4 mb-3">Upload & Edit </h1>

 <form
    method="POST"
    action=""
    enctype="multipart/form-data"
>
    {% csrf_token %}
    {{ form.as_p }}
     <br>
     <h10> upload files.</h10>
     <br>
        <button type="submit" class="save btn btn-default">Save</button>
    </form>
</div>
{% endblock %}

视图.py

def newFile(request, project_name):
    check = auth_test(request)
    if request.method == "GET":
        form = FileForm()
    elif request.method == "POST":
        form = FileForm(request.POST, request.FILES)

        if form.is_valid():
            post = form.save(commit=False)
            post.origin_date = timezone.now()
            post.final_date = timezone.now()
            post.user_name=check['user_name']
            post.project_name=check['project_name']
            post.save()
            return redirect(reverse('mainProject', kwargs={'project_name': project_name}))
    ctx = {
        'project_name' : project_name,
        'form': form,
        'check': check
    }
    return render(request, 'Project/projectEdit.html', ctx)

追溯 ：

  40.             number = int(number)

During handling of the above exception (int() argument must be a string, a bytes-like object or a number, not 'NoneType'), another exception occurred:

Exception Type: PageNotAnInteger at /project/test1/
Exception Value: 페이지 번호가 정수가 아닙니다.
