Custom columns names with @fieldNameAsDatabaseColumn(colum_name) in JDL

[jperezdelafuente]

Overview of the feature request

Related to: #15297

@fieldNameAsDatabaseColumn(colum_name) works well with Jhipster 8.1 to custom column names
But I don't know if this is still an internal feature or could be used since Jhipster 7.2
It is not documented in: https://www.jhipster.tech/jdl/entities-fields
I think this feature for allow custom column names is very interesting and should be documented

Motivation for or Use Case

• You have to 'connect' the new application to an existing database, you cannot align sql column name with java entities field names (usualy sql naming conventions give eyespain).

• You have to respect a java naming convention + a corportate/DBAs SQL naming convention.

In June 2023 there was already doubt about the current status of this feature:

• jdl : specify sql column name for any field #15297 (comment)

I don't know if this is still an internal feature or could be used since Jhipster 7.2
although it works it is not documented in: https://www.jhipster.tech/jdl/entities-fields
Perhaps because it is something internal, which could change suddenly in the future.

I guess, the PR that @mshima mentions is for making this a non-internal feature (by adding some additional test + enhancing the documentation.) ;-)

It’s internal and feature.
Almost every entity aspect is customizable.
https://github.com/jhipster/generator-jhipster/blob/main/generators/app/README.md#customizing

Could be added here

Those properties should be stable for v8 cycle.

PR is welcome to add documentation about this property.
Closing as it’s a minor customization.
