Drupal 8.x

After reading thousands of posts in the issue queue I'm about to drink the poison and learn how to install and update Drupal with composer.  I already had composer installed on my Windows 10 machine so I updated it then started reading instructions and trying to install 8.6.2 (at this writing the latest version).  

In my Windows command box I went through various permutations such as:

"composer create-project drupal-composer/drupal-project 8.x-dev --stability stable --no-interaction"

Hello,

I tried to upgrade from Drupal 8.5.7 to Drupal 8.6.2 and I have this issue:

RuntimeException: Unable to determine class for field type 'text_with_summary' found in the 'field.storage.node.body' configuration in Drupal\field\FieldStorageConfigStorage->mapFromStorageRecords() (line 160 of core/modules/field/src/FieldStorageConfigStorage.php).

I can do update.php. Nothing I have this error. I don't have Drush.

What should I do?

Thanks in advance!

It looks like the docs may have some outdated update instructions:

https://www.drupal.org/docs/8/update/update-core-via-drush

Looks like archive-dump is no longer supported, and ups(pm-updatestatus) is deprecated. What is the correct procedure for updating with Drush now? Is it possible to update the docs?

Thanks!

My cache_page table entries keep getting deleted when loading new pages. It usually saves only record and the record is either deleted or replaced by another record.

The problem is now the pages are very slow. I don't know what I might have done in my installation, but I have no clue where exactly I should be looking.

Best,

Khaled

I want to display a views list of a user name with an image of the last content that has been posted for a specific content type.

I have created the view using a views settings of users.

Basic layout is here.

I used a representative node of authored on and then added the field of the book image. But this only partly works as if a different piece of content has been added by the user then the image is blank. I have tried filtering by Content type but this doesn't work either.
