[13.0][OU-FIX] website_slides: categories migration

[chienandalu]

The fields is_preview and is_published are values expected be True as default when the category is created. It can be seen how in the create() and in the write() this is explicitly evaluated as long as in the controller, which is the main way to create categories now. Also, we must ensure that those categories are active. Al should be as the old specific model didn't have the field itself.

We should also decide what to do with public slides. In v12, they were public or not. In v13 with the eLearing orientation they're visible only if:

• They are free previews (field is_preview set to True)
• The user is subscribed to the channel.

So to translate that from one version to the other we should either:

• Set is_preview on (then an ugly Free preview badge is shown.
• Autosubscribe public and portal users.

What's would be the better way?

For the tag for other times, you can put it as [OU-FIX].

For the public thing, are you able to subscribe to groups or to have an auto-subscribe mechanism?

Yes, you can assign groups to the channel and users belonging to them will autosubscribe. Otherwise, only portal and internal users can subscribe manually (I should check this fact) to the public channels in order to view their slides.

Then the migration script can subscribe automatically Portal and Public groups to this public channels for equivalent behavior, isn't it?

Yes if we choose that way to go :) The other is to set those slides as is_preview, which has the lateral effect of showing that ugly label. So answering myself 😅 , yes the more seamless method will be autosubscribing those groups
