How to i write relationships to bellow three entity's?
If Suppose we have three entity's
entity UserProfile { firstname String
lastname String
}
For the above entity primary key will generate automatically, same as we have another entity
entity SomeTest {
unittest String
}
entity Work{
correction String
}
For the above entity's primary key will generate automatically, So now in user profile entity we have two user records one is student and another one is teacher, in Some Test entity we have one test record that record have key ,so now how can i create relation to add user profile( student nd teacher primary keys) and Some Test Primary key to Work entity.
Please can u write me the relationship to add userprofile & SomeTest Entity primary keys to Work Entity? ans like (relationship OneToMany{}) and what relation it will be and why?
difficult to understand what you are trying to do here. It's better if you can provide your use case in plain english. Accordingly we can help you to create your domain model

Hello @ChaitanyaChowdary Divi,
As per i understood, your flow is like this,
UserProfile( userid(pk) )
UnitTest( testid(pk) )
WorkOrder( userid(fk-One to Many), testid(fk-One to One) )
Right!!!
If it is right then you should follow this way,
Jhipster provide three way to generate relationship.
Case 1 : Uni-Directional Relationship
relationship ManyToOne {
WorkOrder{userid} to UserProfile
}
Note : If you use OneToMany(reverse order) it is compalsary to define field name of parent table.
relationship OneToOne {
UnitTest{testid} to UserProfile{testid}
}
Case 2 : Add using Terminal - command line
yo jhipster:entity entityName
Case 3 : Manually add in coding,
@OneToOne(mappedBy = "UnitTest")
@JsonIgnore
private UnitTest unitTest;
Add column block in XML file.
Resource -> config -> liquibase -> changelog -> entity.xml
<changeSet id="add specialization column" author="jhipster">
<addColumn tableName="specialization">
<column name="specialization_id" type="bigint">
<constraints nullable="false"></constraints>
</column>
</addColumn>
</changeSet>
Apply this changes in JSON file also.
/.jhipster/entity.json
{
"relationshipType": "many-to-one",
"relationshipName": "specialization",
"otherEntityName": "specialization",
"otherEntityField": "id"
},
