How to update entity partially

[punitdwivedi]

Hi,

I have an entity Userinfo having many fields. Some are with NotNull and some allows null value.

Method Signature:

@RequestMapping(value = "/userinfo/{id}/update", method = RequestMethod.POST)
public String updateintercept(@Valid Userinfo userinfo, BindingResult result, ModelMap modelMap,HttpServletRequest request) {
...........
}

Entity: Userinfo
Fields:

userid(NotNull ),
password(NotNull ),
emailId(NotNull ),
phone,
enable(NotNull ),
creattionDate(NotNull ),
updationDate(NotNull )

Now I want to update selected fields like email, phone, enable.
I don't want to populate those fields into the form which are not getting updated.
result.hasErrors() method returning true.

Please suggest me the required changes in my code.

Thanks & regards,
Punit Kumar Dwivedi

I assume you dont want to update the creation date in this case,

You can use JPA @Column(updatable = false)

I have a similar setup which uses a BaseEntity with userWhoCreatedd/timeCreated , userWhomodified/Timemodified updated with Aspects,

I have similar problem, but JPA with 'updatable' is not what I want. I have form that need to update only one field i.e. 'phone' (I don't want to populate in the page all fields like 'password', 'enable', ...).

Hi entaroadun7,

You should user following annotation for password, enable.
@Column(updatable=false)

Hi,

I can't use 'updatable=false' because I have other forms where I allow to change password and enable.

Well in that case you will need to have to write a custom form, controller and validator.

You can probably reuse the form and controller with some if statements but the controller uses imlicit validator for your entity in ROO.
