Nothing is showed after adding computed field

Dear developers of the module,
Could you provide a forceful documentation how to use for D9 or D10?
I believe, at least it could be possible to place screenshots on there.

After installing the module, nothing happens... there is not a field where to put a code snippet.

Only what i see:

The hook implementation function signature should be computed_field_field_<name>_compute($entity_type_manager, $entity, $fields, $delta), and the desired value should be returned.

The variables available to your code include:

    $entity_type_manager: The entity type manager.
    $entity: The entity the field belongs to.
    $fields: The list of fields available in this entity.
    $delta: Current index of the field in case of multi-value computed fields (counting from 0).
    $value: The resulting value to be set above, or returned in your hook implementation).

How did it work for D7?

/admin/structure/types/manage/{name}/fields/field_discount

Computed Code (PHP) 

if ($entity->cost > $entity->sell_price && $entity->cost > '0.00' && $entity->sell_price <> $entity->cost){
$entity_field[0]['value']= ($entity->cost - $entity->sell_price)* 100 /  $entity->cost;  
}
else{
 $entity_field[0]['value']='';}

Display Code (PHP) 

if ($entity_field_item['value']  > 0 ){
$display_output = '-' .round($entity_field_item['value'], 0)." %";  
}
else{
$display_output = '';}


Or was it meant to add obligingly a custom module?


- lot of stress with Drupal 9/10

    If you're looking at those docs, then you're using the 3.x version, not the 4.x. The 3.x version is not very actively supported.

    'hook implementation' means that you need a custom module, yes.

    Thank you for your quick reply!

    ... about v4:

    php82 /usr/local/bin/composer82 require 'drupal/computed_field:^4.0@alpha'

    /admin/structure/types/manage/video/fields

    - upon verbose error level enabled ($config['system.logging']['error_level'] = 'verbose';)

    <em>Error message</em>
    Deprecated function: Creation of dynamic property Drupal\computed_field\Form\ComputedFieldForm::$pluginManager is deprecated in Drupal\computed_field\Form\ComputedFieldForm->configureEntityViewDisplay() (line 300 of modules/contrib/computed_field/src/Form/ComputedFieldForm.php).

    Drupal\computed_field\Form\ComputedFieldForm->configureEntityViewDisplay('computed_php') (Line: 250)
    Drupal\computed_field\Form\ComputedFieldForm->submitForm(Array, Object)

    Drupal\computed_field\Form\ComputedFieldForm->submitForm(Array, Object)

    Computed value source:
    (the only one option) Reverse entity reference
    Entity reference field:
    Entity ID on Comment entities

    /admin/structure/types/manage/video/display

      All, what i see, is just a possibility to switch format:
    • rendered entity
    • entity id
    • label



    As for me, i do not have deep programming skills.
    My experience of D7 computed field doesn't allow to comprehend your module for the latest versions of Drupal - D{9,10}, it is really hard to figure out how to deal with.

    Could you file a separate issue for that please?

    Have you read the README? That explains how to set up the module.
