Question

我在处理具有FormView的视图时遇到问题。我正在尝试使用s3direct插件。

错误指定'<app.views.MyView object at 0x7f7dd9222250>' is not a callable or a dot-notation path。

我的观点

class MyView(FormView):
     template_name = 'form.html'
     form_class = S3DirectUploadForm

Forms.py

class S3DirectUploadForm(forms.Form):
    images = forms.URLField(widget=S3DirectWidget(
        dest='destination_key_from_settings',
        html=(
            '<div class="s3direct" data-policy-url="{policy_url}">'
            '  <a class="file-link" target="_blank" href="{file_url}">{file_name}</a>'
            '  <a class="file-remove" href="#remove">Remove</a>'
            '  <input class="file-url" type="hidden" value="{file_url}" id="{element_id}" name="{name}" />'
            '  <input class="file-dest" type="hidden" value="{dest}">'
            '  <input class="file-input" type="file" />'
            '  <div class="progress progress-striped active">'
            '    <div class="bar"></div>'
            '  </div>'
            '</div>'
        )))

urls.py

    urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^s3direct/', views.MyView()),

]

非常感谢任何帮助。

在网址中使用基于类的视图时，您应该调用.as_view()方法。

替换它：

url(r'^s3direct/', views.MyView()),

有了这个：

url(r'^s3direct/', views.MyView.as_view()),

Django FormView：/ s3direct上的ViewDoesNotExist /
