In Django admin, tweet on initial save?

Question

I am using Django, and I have recently created a blog as my first Django/python project. I decided to use the default admin area for my blog management system, for simplicity. I would like to automatically post a twitter update when I initially create a blog post, but not when I edit it. I know how to send the tweet, but how would I run some code on the initial save of the post, and not after edits?

I'm using Django 1.5.4 and the model for blog posts is simply called "Post".

Answer 1

you can do this in at least two ways: You could override the model's save method like this:

class Post(models.Model):
    ...
    def save(self, *args, **kwargs):
       if not self.pk:
         #tweet about the post
       super(Post, self).save(*args, **kwargs)

..but if you want to associate this behavior only with django admin (e.g. you want to tweet about a post only when it is created through the admin app and not when explicit calls to Post.objects.create() are made), then you can use the save_model() method of the ModelAdmin class:

class PostAdmin(admin.ModelAdmin):
   ....
   def save_model(self, request, obj, form, change):
      if not obj.pk:
         #tweet about the post
      obj.save()
