Drupal 8.x

I created a custom module to create a /group/ID/tasks page

How to limit access to this page to the group administrator ?

If the current user is administrator of group ID 76, he can access this page :

/group/76/tasks

But if he goes to another group, he must have denied access :

/group/89/tasks

I created a custom module to create a /store/ID/tasks page

https://www.drupal.org/project/commerce

How to limit access to this page to the store owner ?

If the current user is owner of store ID 76, he can access this page :

/store/76/tasks

But if he goes to another store, he must have denied access :

/store/89/tasks

I have a D6 site which I need to migrate to D8.  The big obstacle keeping this from happening long ago is that the site makes extensive use of tablemanager, which has not been maintained for a long time and was last supported on D6.  Now, however, there is no real choice in having to move.  A suggestion was made that we consider contentimport, but my impression is that it is not an ideal fit.

Hi guys,

I'm stucked with Drupal8 to Drupal 8 paragraphs migration with structure changes

I have content type news, that contains paragraph field blog_section, that is unlimited and news page can contain many such field paragraph items

I am no longer able to update the pages when I have put content of paragraphs type. I can submit if I edit any other type like Rich text but if I edit text and image type I get a 403 Forbidden error saying I don't have permission to access node this on this server. I am logged in as user 1 administrator.

I'm interesting to use Drupal in the Cloud ¿How to test this?

Thanks in Advance for this question
