Hi,
There are several entities which have 1:n relationship in our SaaS
application. For the sake of simplicity and keeping the domain simple,
I tried the same concept with a small application but still found that
the configuration file formed with the BulkLoader did not respect
relationships.
For example,
I have 2 entities User and UserDepartment. They are related to each
other with a n:1 relationship.
@Entity
public class User extends DomainObject<Long, User> {
...
@ManyToOne(fetch = FetchType.EAGER)
private UserDepartment userDepartment;
...
}
and
@Entity
public class UserDepartment extends DomainObject<Long, UserDepartment>
{
...
@OneToMany(mappedBy = "userDepartment", cascade = CascadeType.ALL,
fetch=FetchType.EAGER)
private Set<User> users = new HashSet<User>();
...
}
Now when I try to create a configuration file for my application with
a command like this
bulkloader.py --create_config --url=http://appname.appspot.com/
remote_api --application=appid --filename=generated_bulkloader.yaml
I see the following results in the generated_bulkloader.yaml
- kind: UserDepartment
connector: csv
connector_options:
encoding: utf-8
columns: from_header
property_map:
- property: __key__
external_name: key
export_transform: transform.key_id_or_name_as_string
- property: name
external_name: name
# Type: String Stats: 16 properties of this type in this kind.
and
- kind: User
connector: csv
connector_options:
encoding: utf-8
columns: from_header
property_map:
- property: __key__
external_name: key
export_transform: transform.key_id_or_name_as_string
- property: email
external_name: email
# Type: String Stats: 17 properties of this type in this kind.
- property: firstName
external_name: firstName
# Type: String Stats: 17 properties of this type in this kind.
- property: lastName
external_name: lastName
# Type: String Stats: 17 properties of this type in this kind.
- property: password
external_name: password
# Type: String Stats: 17 properties of this type in this kind.
- property: salt
external_name: salt
# Type: Integer Stats: 17 properties of this type in this kind.
import_transform: transform.none_if_empty(int)
Hence there is no mention of either entity in either kind. Am I
missing something? Is there something that i can add to the generated
yaml file to fetch the relationships.
