In JHipster how to create entity with relationship

问题:

I need to create my own entities using the JHipster using the command "yo jhipster:entity myEntity" that have many-to-one relationship with the User entity that comes by default in JHipster.

I have tried unsuccessfully to create in the wizard a relationship with the entity "user" and the field "login" but it is not working.

What is the good way to do this with JHipster? Or do I have to create the entity without JHipster tool (but I need the CRUD!).

Thanks,

Yann

Just an update - jhipster 2.5.0 was released a few days ago adding support for this. Created this answer since the formatting in comments make i pretty hard to read.

When creating a relation for your entity simply answer the questions like this

? Do you want to add a relationship to another entity? Yes
? What is the name of the other entity? user
? What is the name of the relationship? owner
? What is the type of the relationship? many-to-one
? When you display this relationship with AngularJS, which field from 'user' do you want to use? login

Possible values on how to display the relation could be: id, login, first_name, last_name, email

See https://jhipster.github.io/2015/03/01/jhipster-release-2.5.0.html for moreinformation

Just to add to the correct answer by @stoffer, if you're using the jdl it will look like:

relationship ManyToOne {
    Owner{user(email)} to User{owner(name)}
}

If you are using the 1.x version, this wasn't made to work, so basically you should do it by hand, without the generator (but it is definitely doable). For the 2.x version, we have refactored the User object to have an ID field -> this should make this a lot easier, but as this is not released yet, we don't have a feedback at the moment.

at a good sample in an official document is say :

entity Blog {
    name String required minlength(3),
    handle String required minlength(2)
}

relationship ManyToOne {
    Blog{user(login)} to User 
}
