What happens when we try to create a project with already assigned employees, will JPA take care of all the assigned employees by populating the third table? Like you are adding employees after the project creation one by one, what if I want when creating the project itself I want bulk adding of employees?

[@toetoeag]

Thank you very much.

[@frenkie1212]

I love you smart Indian wizard! This helped a lot. I do have one question though: is there a way to create an Employee with a Post method that also takes in input a set of Projects? Ill' try to explain it better. In the video you create an Employee, you create a Project and then you add the projects to the employee one by one. I'm looking for a way to add multiple projects to the employee when I'm creating the employee. So in your example when creating the employee I would like to pass a name (employee name) and a set that contains multiple projects.

[@dev2prodcoding]

Thanks...Glad that you liked it. Is there a way to create an Employee with a Post method that also takes in input a set of Projects? -> Yes, it can be done. You can use one-to-many mapping to add multiple projects to the employee. You can check kzbin.info/www/bejne/aJfZhqWmjqxsa9k for more on this.

[@hariommahajan4788]

Very nice explained..👏 Sir please make video on how to remove assigned project for particular emp.

[@tonycavanagh1929]

JsonIgnore stops the circular but also stops adding employee to Project, so just makes it a more complex one to many.

[@johnvick8861]

Use @jsonbackreferrence on top of get method

Thank you, what i do whene i want to assign project to Employee ?

[@TheKnightKing007]

if u want assign one project to one person means go for @OneToOne, if multiple project to one person mean go for @OneToMany, if one project involved to many persons means @ManyToOne if Many person collap with many project means go for @ManyToMany

[@cvgaviao]

What if the relationship has attributes ?

[@nishantsingh4366]

From where you got getAssignedProjects()in service

[@dev2prodcoding]

Please check Employee entity class, there I have defined private Set assignedProjects = new HashSet(); getAssignedProjects() is the getter method for the same which is auto generated by lombok.Data annotation. Hope it helps!
