python - django 表单未验证

Question

所以我一直在尝试实现一种在我的网站上发布项目帖子的方法。但是，我的表单验证似乎有问题。即使表单正确且完整，它仍然无法验证。

我的项目页面中没有发布任何帖子，我的数据库中也没有添加任何内容。我不确定发生了什么。

我在终端中没有看到任何错误。

我的代码如下:

View .py

class CreateProjectsView(View):
    def get(self, request):
        p_photos = P_Images.objects.all()
        #project_form = ProjectsForm(initial=self.initial)
        project_form = ProjectsForm()
        context = {
            'p_photos': p_photos,
            'project_form': project_form,
        }
        return render(self.request, 'projects/forms.html', context)

    def post(self, request):
        project_form = ProjectsForm(request.POST or None, request.FILES or None)
        p_formset = P_ImageForm(request.POST, request.FILES)

        # Checks if the project_form is valid before save
        if project_form.is_valid():
            instance = project_form.save(commit=False)
            instance.user = request.user
            instance.save()

        # Checks if multiple image upload is valid before save
        if p_formset.is_valid(): 
        #if project_form.is_valid() and p_formset.is_valid():   
            #instance = project_form.save(commit=False)
            #instance.user = request.user
            #instance.save()
            images = p_formset.save(commit=False)
            images.save()

            data = {
                'is_valid': True, 
                'name': images.p_file.name, 
                'url': images.p_file.url
            }

        else:
            data = {
                'is_valid': False,
            }

        return JsonResponse(data)

表单.html

{% extends "projects/test.html" %}

{% block javascript %}

    {% endfor %}

    <input type="submit" value="OK">

       data-form-data='{"csrfmiddlewaretoken": "{{ csrf_token }}"}'>

{# 3. TABLE TO DISPLAY THE UPLOADED PHOTOS #}
<table id="gallery" class="table table-bordered">

    <tr>
      <th>Photo</th>
    </tr>
  </thead>
  <tbody>
    {% for p_photo in p_photos %}
      <tr>
        <td><a href="{{ p_photo.file.url }}">{{ p_photo.file.name }}</a></td>
      </tr>
    {% endfor %}
  </tbody>
</table>

    <h1>hahahaha</h1>

</form>

{% endblock %}

这个问题已经困扰我两周了。它开始阻止我在 python 中学习 django :(

您的表单操作指向 create_post:retrieve_projects 更改它，使其指向 create_post:create_projects
