在Flask-admin ImageUploadField中覆盖data_template

Question

我试图从data_template中存储的HTML标记中删除delete-checkbox。有没有办法只覆盖data_template或者我必须继承整个ImageUploadField吗？

您必须先创建窗口小部件的实例，然后重写字段本身。解决方案：

class ImageFieldWidget(admin.form.ImageUploadInput):
    data_template = ('<div class="image-thumbnail">'
                     ' <img %(image)s>'
                     '</div>'
                     '<input %(file)s>')

class ImageField(admin.form.ImageUploadField):
    widget = ImageFieldWidget()
