Django Admin，Call功能保存 [英] Django Admin, Call function on save

问题描述

我在Django网站上有一个处理博文的应用程序。当发布博客文章时，我想在第三方应用程序上安排一个通知，通知订阅者新帖子。

所以我想添加一个自定义函数当博客文章被保存在哪里时，我可以将这个API调用写入通讯服务。

如何做？试图查看文档，所有我可以找到的是管理操作，似乎不是我正在寻找的。

解决方案

p>有很多方法可以使用。

覆盖模型保存方法很简单，但每次保存模型时都会调用该方法。

https://docs.djangoproject.com/en/1.8/ref/models/instances/#saving-objects

如果它是特定于管理站点，在您的ModelAdmin中使用model_save（）方法。 （我个人喜欢这种方法，因为它不会干扰你的模型）。

https://docs.djangoproject.com/en/1.8/ref/contrib/admin/#django.contrib .admin.ModelAdmin.save_model

您还可以使用帖子保存信号，但保存方法似乎是首选（取决于您在做什么）<一个href =https://stackoverflow.com/questions/5597378/django-when-to-customize-save-vs-using-post-save-signal> Django：何时使用保存后信息自定义保存/ a>

I have a app in my Django site that handles blog post. When a blog post is published I want to schedule a Newsletter on a third party application that informs the subscribers of the new post.

So I want to add a custom function to be called when the blog post is saved where I can write this API call to the newsletter service.

How to do this? Tried looking through the documentations and all I can find is Admin Actions which doesn't seem to be what I'm looking for.

解决方案

There are a number of approaches you could use.

Override the model save method is simple, but will be called every time the model is saved.

https://docs.djangoproject.com/en/1.8/ref/models/instances/#saving-objects

If it is specific to the admin site, in your ModelAdmin use the model_save() method. (I like this approach personally, as it won't interfere with your model).

https://docs.djangoproject.com/en/1.8/ref/contrib/admin/#django.contrib.admin.ModelAdmin.save_model

You could also use a post save signal, but save methods seem to be preferred (depending on what you are doing) Django: When to customize save vs using post-save signal
