I have a user authorized to enter and modify the nodes he owns.
In the view of this content type I show the links for insertion and modification. So far, so good.
Now I need to check, based on a logical field if it can modify the node.
Ex .:
The content type has a logical field. If this field is false it can modify. If true it should hide the link to the edit (in the views), or in the form check this and prevent it from editing.
In the various readings I have done I have found this code but it does not work for me

I am trying to automate the process of enabling/disabling the module for my Drupal-8 website. As far I could understand from the docs, Drupal saves the info related to the modules in the table config inside it's database (Drupal/sites/default/files/.ht.sqlite).

I'm developing a complex AJAX form and it works under the core themes, like Bartik. But switching to the customer's theme brings up this error when submitting the form.

Ah, you say that clearly this theme function is goofed up. To ensure it wasn't something in my form code, I copied over the ajax_addmore from the examples project which is much simpler to walk through and debug.  I wish it were as simple as that, but in watching it go through the ajax_addmore form it doesn't bail as it goes through each of the AJAX steps. When it bails on the submit step, it fails at line 1008

I have a few hundred users in a plain vanilla Drupal 9 instance on my local machine. They were created using the standard Drupal migration tool from our production Drupal 6 website. I need to get these users copied into our new production Drupal 9 site which is currently under construction. I have tried a few of the migration tools available but - at least any way I have tried so far - they have totally hosed the new web site.
