有人可以告诉我在哪里可以找到 Flask-Admin 回调吗？
Could someone please show me where I can find Flask-Admin callbacks?
我正在尝试结合 Flask-Admin 和某人编写的 Flask S3 Tool Suite 将图像存储到 Amazon S3 简单存储。我尝试专门使用的工具是 S3Saver 功能，在文章 link 中，用户继续说要合并此工具，我最好在 flask-admin 回调中使用它。
但是，我无法在任何地方找到 Flask-Admin 回调列表。我已经完成了我的作业，并且我已经从字面上检查了这些回调的整个文档和源代码 Flask-Admin documentation 。
在 flask_admin.contrib.sqla 中，我发现了一些类似于回调的方法，但它不是我要找的。我想它是接近 Rails 的 before_action 和 after_action 的东西。有人可以给我指出正确的方向吗？
顺便说一句，这是文章
中的实际引用
If you wanted to handle deleting files in the admin as well, you could (for example) use s3-saver, and hook it in to one of the Flask-Admin event callbacks
那些回调是什么？
这是 Flask 管理事件的文档：
on_form_prefill(form, id) Perform additional actions to pre-fill the edit form.
Called from edit_view, if the current action is rendering the form
rather than receiving client side input, after default pre-filling has
been performed.
By default does nothing.
You only need to override this if you have added custom fields that
depend on the database contents in a way that Flask-admin can’t figure
out by itself. Fields that were added by name of a normal column or
relationship should work out of the box.
Parameters: form – Form instance id – id of the object that is going
to be edited
on_model_change(form, model, is_created) Perform some actions before a model is created or updated.
Called from create_model and update_model in the same transaction (if
it has any meaning for a store backend).
By default does nothing.
Parameters: form – Form used to create/update model model – Model
that will be created/updated is_created – Will be set to True if model
was created and to False if edited
on_model_delete(model) Perform some actions before a model is deleted.
Called from delete_model in the same transaction (if it has any
meaning for a store backend).
By default do nothing.
Flask-Admin 回调函数（据我所知）
after_model_change(form, model, is_created)
#Called from create_model after successful database commit.
after_model_delete(model)
#Called from delete_model after successful database commit (if it has any meaning for a store backend).
on_form_prefill(form,id)
# Called from edit_view, if the current action is rendering the form rather than receiving client side input, after default pre-filling has been performed.
on_model_change(form,model,is_created)
#Called from create_model and update_model in the same transaction (if it has any meaning for a store backend).
on_model_delete(model)
# Called from delete_model in the same transaction (if it has any meaning for a store backend).
