django-image-cropping在管理界面中不起作用

I'm using django-image-cropping in my django project and I followed the official guidelines but still I'm not getting the desired result. Here the snippet of my project files.

我在我的django项目中使用django-image-cropping，我遵循官方指南，但仍然没有得到理想的结果。这是我的项目文件的片段。

I already added easy_thumbnails and image_cropping to my INSTALLED_APPS.

我已经将easy_thumbnails和image_cropping添加到了我的INSTALLED_APPS中。

settings.py

settings.py

from easy_thumbnails.conf import Settings as thumbnail_settings
THUMBNAIL_PROCESSORS = (
    'image_cropping.thumbnail_processors.crop_corners',
) + thumbnail_settings.THUMBNAIL_PROCESSORS

models.py

models.py

from django.db import models
from image_cropping import ImageRatioField    
class UserData(models.Model):
        fullname = models.CharField(max_length=255)
        user = models.CharField(max_length=70, unique=True, blank=False, null=False)
        image = models.ImageField(upload_to=generate_filename,blank=False, null=False)
        cropping = ImageRatioField('image', '180x180')

admin.py

admin.py

from django.contrib import admin
from image_cropping import ImageCroppingMixin
class UserDataModelAdmin(ImageCroppingMixin, admin.ModelAdmin):
    # filter_horizontal=['image']
    pass

admin.site.register(UserData, UserDataModelAdmin)

As per the official guidelines its enough to see the enhanced selection area in the admin panel, but I'm not getting it. Instead I'm getting this. django-image-cropping在管理界面中不起作用

根据官方指南，它足以看到管理面板中增强的选择区域，但我没有得到它。相反，我得到了这个。

No option for cropping.

没有裁剪的选择。

Please help me to sort this out.

请帮我解决这个问题。

Use this tool django-imagekit-cropper, it has nice features and very good documentation. you need to create a form.py file and need to mention this

使用此工具django-imagekit-cropper，它具有很好的功能和非常好的文档。你需要创建一个form.py文件，需要提一下

from django import forms
    from imagekit_cropper.widgets import ImageCropWidget    
    from .models import UserData


    class ImageAdminForm(forms.ModelForm):
        square_150_crop = forms.CharField(widget=ImageCropWidget(properties=Image.square_150_crop_properties, help_text=Image.help['square_150_crop']))

        class Meta:
            model = UserData

Though this isn't covered in the documentation, I found that I needed to add the cropping attribute from my model to my custom UserAdmin fieldsets:

虽然文档中没有介绍，但我发现需要将模型中的cropping属性添加到自定义的UserAdmin字段集中：

fieldsets = (
    (None, {'fields': ('email', 'password')}),
    ('Personal info', {'fields': ('first_name', 'last_name', 'gender',
        'phone', 'address', 'postal_code', 'city', 'student', 'university',
        'newsletter', 'birthday', 'avatar', 'cropping')}),

Where my image attribute is alternatively names avatar.

我的图像属性也可以是头像。
