What about to add a page copied signal?!

[Philippe O. Wagner]

Hi all

We are missing a signal that will be fired after a page was copied using page.copy_page? 
Would this be helpful for anybody else?

Hello Philippe,

I've not had a case where a signal for this is needed.

I'm not against adding it there's an interest by the community but it would require some refactoring on the cms core,

this is because the cms uses copy_page in some internal actions like publishing a page and so it wouldn't be good to trigger

the signal then.

What is the exact use-case? Is it:

* a user-triggered copy action via the web interface
* a copy invoked via the CMS's APIs, by an external application
* a copy action triggered by publishing a page
* something else?

I can imagine that you might want it in one of the first two cases, but not the third, for example, but I don't think the mechanism actually distinguishes between the different ways it might be called.

We extended the CMS with a tagging functionality.

For example a client has tagged project pages (planning, funded, completed, type a, type b, type c). 
This allows us to group pages (all type a projects, all funded or all planned) and link to pages that are in different page trees. 

However, to create a new project page an old one is copied and adapted by the client (= user-triggered copy action via the web interface ). With the current setup all tags are then lost.

Could we work together to get this into the LTS? This would help us in mid- and long-term.

Hello Philippe,

We are in the process of steering the djangoCMS core away from signals.

Although I did mention we might consider implementing your suggestion, it's now clear to us that signals are causing too many problems.

Regarding your specific issue, I think a better way to solve it is using PageExtensions to add the tags to a page.

The cms will take care of the logic behind copying your extensions over to new pages as needed.

Let me know how it goes,

FYI, the PageExtensions link was broken (missing the 'l' in the 'html' file extension), here's the correct url => http://docs.django-cms.org/en/release-3.3.x/how_to/extending_page_title.html

If you're interested in tagging cms page, you may want to have a look at
this https://github.com/nephila/djangocms-page-tags page extension for
reference.
It may not suit your needs, but you can get some inspiration out of it
