Drupal 8.x

I'm trying to build a module that authenticates a user to Drupal based on a HTTP header added by a reverse proxy.

I read that Drupal 8 has a new authentication API, so I initially tried using that. I only half expected it to work, and sure enough, it only half worked: the user was authenticated, but could not submit any forms because (I guess) the CSRF token is linked to a session ID, which they didn't have.

Hello.

I'm new to Drupal 8 and i have 2 questions.

1) Bootstrap is available on the core on Drupal 8 and that means i don't have to download the bootstrap theme?

2) A solid guide to start develop on Drupal with bootstrap.

Thank you!

I created a content type and the corresponding view as well. However, the display mode which should have been shown on Content Type level is actually showing at the node level and vice versa.

The content node display is this https://www.tokyobigsight.com/buying-leads

The individual node display is this https://www.tokyobigsight.com/node/578

Could anyone please let me know how to fix?

Thanks

I'll try to explain, but please ask for further clarification if I'm talking rubbish

I'm trying to consolidate different content types from D6 & D7 into a new D8 system and rationalize the storage requirements at the same time. My thinking is to have a few specific "properties" as a standalone content type that are related to the main node a bit like a polymorphic object, so content type "Master" will have a few attributes that are in common with all variations and then if Master->Type = A pull in content type A, B, C, if Master->Type = B pull in C, D, E and so on.

HI,

I have a Drupal 8.6.1 multisite. I use composer to update the core, but then I have to go one by one of the multisites and execute update.php.

Isn't there a way to do it with all the sites like with drush @sites? I know I'm not supposed to use drush anymore, so how do I do it with Composer?

I have the same question for updating and enabling modules. Isn't there a better way than going one by one...?

Thank you.

I have created a Drupal 8 site and now I need to import contents from an old drupal site 6. How can I do?
