Question

我有两个模型Project，其中包含有关项目的信息，ProjectImage包含与该项目相关的所有图像（多对一关系）。我进行了设置，以便在初始设置期间通过内联格式集上传项目的图像。

当我尝试使用图片创建新项目时，可以使用。 Firebug没有报告任何问题。但我的图片不会上传到媒体目录。据我所知，他们不会去任何地方。

我的问题：

1）。以下代码中是否有任何内容会阻止图片上传？在我看来，图片应该上传到django_project_dir/media/images。

2）。是否有任何工具可以帮助我将来调试这些问题？

文件夹设置：

folder/
    env/
    project_dir/
        app/
        project_dir/
            settings.py
        media/
            images/

Settings.py：

PROJECT_DIR = os.path.realpath(os.path.dirname(__file__))
MEDIA_ROOT = os.path.join(PROJECT_DIR, 'media')
MEDIA_URL = '/media/'

Models.py：

class ProjectImage(TimeStamp):
    project = models.ForeignKey(Project)
    image = models.ImageField(upload_to='images/')

Views.py：

class CreateProject(CreateView):
    model = Project
    template_name = "manage_project.html"
    form_class = CreateProjectForm

    def get(self, request, *args, **kwargs):
        self.object = None
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        project_image_form = ProjectImageFormSet()

        return self.render_to_response(
            self.get_context_data(
                form=form,
                project_image_form = project_image_form,
            )
        )

    def post(self, request, *args, **kwargs):
        self.object = None
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        project_image_form = ProjectImageFormSet(self.request.POST)

        if form.is_valid() and project_image_form.is_valid():
            return self.form_valid(form, project_image_form)
        else:
            return self.form_invalid(form, project_image_form)

    def form_valid(self, form, project_image_form):
        self.object = form.save()
        project_image_form.instance = self.object
        project_image_form.save()

        return HttpResponseRedirect(self.get_success_url())

    def form_invalid(self, form, project_image_form):
        return self.render_to_response(
            self.get_context_data(
                form = form,
                project_image_form = project_image_form,
            )
        )

    def get_success_url(self):
        return reverse('list-project')

Forms.py：

class CreateProjectForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(CreateProjectForm, self).__init__(*args, **kwargs)
        self.fields['name'].label = "Project Name"
        self.fields['description'].label = "Project Description"
        self.fields['github'].label = "Github Link"
        self.fields['public'].label = "Public?"

    class Meta:
        model = Project

ProjectImageFormSet = inlineformset_factory(Project, ProjectImage)

图片上传失败但没有错误输出
