Problem/Motivation

#2183231: Make ContentEntityDatabaseStorage generate static database schemas for content entities revealed that there are large discrepancies between our current schema descriptions and entity type's field definition descriptions. When that issue gets in the latter will end up as schema descriptions directly and schema descriptions will no longer be declared separately.

The current patch over there takes the field definition description for single-column fields as the schema description, but does not do anything with multi-column fields (so far).

Proposed resolution

?

Remaining tasks

- Provide some concrete examples of the differences.

User interface changes

None.

API changes

None.

Note that those those differences might be there explicitly, for example because they are also used as descriptions for form widgets...

Right, I thought about that as well. There are certainly use-cases where in theory you would want different descriptions for your form than for your schema.

However, I think it's questionable whether we want to add a separate field setting for that á la FieldDefinitionInterface::setSchemaDescription() or whatever. I personally think that would be overkill.

We could also decide to not use the field description at all in the schema description, but instead let the field item class handle schema descriptions directly in its schema() function leveraging the passed field definition. I.e.

public static function schema(FieldDefinitionInterface $definition) {
  $schema['columns']['foo']['description'] = String::format('The foo column of the @field field for the @entity_type entity type.' array('@field' => $definition->getName(), '@entity_type' => $definition->getEntityType());
  ...
}

The advantage of that would be that we no longer need to make a distinction between single-column and multi-column fields when it comes to schema descriptions.

Edit: Fix php formatting

However, we do lose the domain-specific description information in the schema. Not sure.

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!

Going to close this one out as there hasn't been any movement in years. But also maybe we should evaluate on a case by case basis vs a standard. May be easier to fix some that route.
