Error in views

My 'buy_amazon.views.inc' file looks like this:

function buy_amazon_views_data() {

  $data['node_field_data']['computed_buy_amazon'] = [
    'title' => t('Buy Amazon'),
    'entity field' => 'computed_buy_amazon',
    'field' => [
      'id' => 'field',
    ],
  ];

  return $data;
}

That looks like the error you get without the core patch -- have you applied that? It's explained in the README.

I'm sorry but I can't find any links to the core patch at https://www.drupal.org/project/drupal/issues/3349739 📌 Automatically declare computed base fields to Views Needs work .
Could you provide a link so I can add it to my composer.json and give it a test?

Argh I mixed up the issue numbers.

It's this one: https://www.drupal.org/project/drupal/issues/2981047 📌 Allow adding computed bundle fields in Views Fixed

I'll fix the README.

I'm guessing it's #118 so I added " https://www.drupal.org/files/issues/2023-02-23/2981047-118.patch → " to my composer.json . I ran 'composer update', and 'drush cr', still getting the same error. Isn't that the correct patch for a D10 site? It didn't give me any errors when I ran update, but it also didn't say it was loading the patch.

The patch says it's for 10.1

You're better off using the diff from the MR, as that is more recent.

> It didn't give me any errors when I ran update, but it also didn't say it was loading the patch.

You mean `composer update` didn't tell you it was deleting Drupal to patch it? Then the patch has not been applied.

Still getting the same PHP error. This is a new 10.1 test site so not much on it but my one test page.
Here's what I did. I ran 'composer require cweagans/composer-patches:~1.0 --update-with-dependencies'
Here is the exact lines I added to my composer.json:

        "patches": {
            "drupal/views": {
                "computed base fields to work in Views": "https://www.drupal.org/files/issues/2023-02-23/2981047-118.patch"
            }
        },

I ran composer update and saw:

Maybe I'm using the wrong patch URL?

I finally think I have it! I changed composer.json to:

        "patches": {
            "drupal/core": {
                "computed base fields to work in Views": "https://git.drupalcode.org/project/drupal/-/merge_requests/4224.diff"
            }
        },

Not the errors are gone and the field works in Views. If anyone wants to see my simple module for an example please let me know.

Well that's applying. But like I said, you might be better off trying the diff from the MR instead.

I thought https://git.drupalcode.org/project/drupal/-/merge_requests/4224.diff was the correct diff

Sorry -- cross-posted with your comment about applying the diff.

Glad to hear you got it working!
