email id should not added morethan once in model.

[former_member649347]

I have a model and storing email to that. but how would I stop allowing duplicate entry on model. even in items.xml i have made it as unique.

items.xml:

                 <persistence type="property" />
                     <modifiers unique="true" optional="false" initial="true" />

ex: final NewsLetterEmailModel emailModel = new NewsLetterEmailModel(); emailModel.setEmail(email); modelservice.save(emailmodel)

regards, Mohiddin

How to restrict allowing duplicate entries to model? do i need to use interceptor's? plz suggest

I created my key as unique=true and receiving this following exceptions::

SEVERE: Servlet.service() for servlet [DispatcherServlet] in context with path [/store] threw exception [Request processing failed; nested exception is de.hybris.platform.servicelayer.exceptions.ModelSavingException: [de.hybris.platform.servicelayer.interceptor.impl.UniqueAttributesInterceptor@15d0402e]:ambiguous unique keys {Email=test@test.com} f or model NewsLetterEmailModel () - found 1 item(s) using the same keys] wit

Before saving a new NewsLetterEmailModel you should query your database if an entry with the same email value already exists.
