Specify custom "Success" messages per list

[jesstelford]

What

Imagine this flow:

• I run a blog site where people can submit their own posts.
• I receive an email telling me I got a new post.
• I click the link to load up Keystone on that post.
• I now have to change the status to Approved
• I click Save
• An email is sent to the author, and the post is now live on the site
• I see:
  

That success message " Saved Successfully" is not very informative of what actually happened.

Ideally, I'd be able to specify a custom message to better describe what happened (an email was sent, and the post is live at <url>). Something like:

How

One possible solutions is as part of the afterChange() hook (which currently expects undefined as the return type);

keystone.createList('Post', {
  fields: {
    approved: { type: Checkbox },
    /* ... */
  },
  hooks: {
    afterChange({ updatedItem, existingItem }) {
      if (updatedItem.approved && !existingItem.approved) {
        sendApprovalEmail(updatedItem);
        return {
          message: `
**${updatedItem.title}**

✅ Changes saved successfully.<br />
✉️ ${updatedItem.author.name} has been notified of approval.<br />
🔗 <a href="${updatedItem.url}">View the post online here</a>
          `,
        },
      }
    },
  },
});

I think this is more than custom actions
