Thank You!!

[@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 ruclips.net/video/2fvUrpYG95w/видео.html for more on this.

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?

[@nooruddinraotiwala353]

how does scenario looks in db that u didnt show what happened to the joineTable ???

[@hariommahajan4788]

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

[@MultiCrashcar]

I LOVE YOUUU BROOO!! THANKS

[@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

[@FutureTech_Explorers]

Finally i have found.....What i excellently want.

[@dev2prodcoding]

Glad to hear that!!

[@yahyawins0550]

Bro, what about the sql sripit ,

[@medyazidhamlaoui2703]

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

[@satyadasari1485]

how can i do if i want employee list in particular project along with project details ???

[@massimoramaj3233]

Is there any specific reason why you did not use @Getter and @Setter in employee entity?

[@sandhyalakshmi1697]

I'm getting stack overflow error...even after using @JsonIgnore.... actually I'm using DTO classes

[@chetankarale5987]

I am getting same error

[@cvgaviao]

What if the relationship has attributes ?

[@ASGARDIAASGARDIA]

In MYSQL Workbench the project is assigned to employee/s but in Postman it doesn't show to be assigned. What could be the problem?

[@ranjitchill]

When I'm updating the record It is showing Customer with projects but when I'm try to get all records or find by id It is showing [ ] for projects.
I don't understand why ?
Can you help....Pls.

bhai tera project kisi kam ka nhi hai...tum ache ache comment khud hi fake account se karte ho kya

[@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!
