JPA2DataSource exclude fields question

[zdary]

Hi,

I cannot figure out how to exclude some fields for either validation or serialization. I tried to set dropExtraFields but it didn't work.

<DataSource ID="usersDS"
        serverConstructor="com.isomorphic.jpa.JPA2DataSource"   
        schemaBean="cz.bcom.smartrise.server.persistence.hibernate.UsrUsers"
        dropExtraFields="true">  
	<fields>

1) when I try to add a new user it leads to a VALIDATION_E because ID field is missing. ID gets generated by a database trigger on insert.

	@Id
	@GeneratedValue(strategy = IDENTITY)
	@Column(name = "ID", unique = true, nullable = false)
	public Integer getId() {
		return this.id;
	}

2) I have a field pwd which is mandatory in the entity. It holds encripted password. I don't want this field to send over at all.
I defined a new field in the ds.xml password which acts as plain text password field.
In DMI I used to convert password field into pwd.

What would be the best way to achieve this?

3)
Another field I don't want to send across is byte[] which can be large. It holds *.PDF files.

4) Ideally, I'd like to send over and validate only fields which I explicitly defined in ds.xml The same way it works for DMI data sources.

I set some fields just before add or update. for example I set who made a last change on the object. Those fields are mandatory on the entity but they shouldn't be set on the GUI.

best regards,
Zdary

dropExtraFields="true" will prevent fields being delivered to the client *if you do not declared them in your dataSource". As far as #1, this sounds like you've declared the field as required="true", but an auto-generated field should not be declared this way (the user does not need to enter a value, which is what "required" means).

Hi,

in the end I found out that my DS was misconfigured.
dropExtraFields is ignored when schemaBean is defined.

I defined schemaBean instead of beanClassName.

The solution is

<DataSource ID="usersDS"
        serverConstructor="com.isomorphic.jpa.JPA2DataSource"   
        beanClassName="cz.bcom.smartrise.server.persistence.hibernate.UsrUsers"
        dropExtraFields="true">

best regards,

To clarify:
dropExtraFields is not ignored.
When you define schemaBean all mapped fields are declared in data source.
Fields can not be dropped, because they are declared.

I see, that makes sence.
