Hi someone can help me with this question?

https://stackoverflow.com/questions/72805200/problem-with-populating-a-dropdown-list-manytoone-spring

guess your endpoint is different. You’re adding cateogories to the model in one method, but the form action points to another.

And what is the solution?

The system iterate the list in the spring form but when I save a new Product it save also the Category… So i can’t add a product because the category have unique index and I got the exception of duplicate key

How can i solve the problem?

The tag form:select have the path=”category” and items=”${categories}” which is the list of the categories

You should have driver-class-name

Spring.datasource.driver-class-name

yes. That’s what I was referring to.

You have
<form:select path=”category”>
<form:options items=”${categories}”></form:options>
</form:select>

under the form which point to method createProductForm.
<form:form action=”createProductForm”

But, the categories is added to the model, only in this method.
@GetMapping(“/createProd”)
public ModelAndView createProduct(@ModelAttribute(“newProduct”) Product p, Model model) {

List<Category> categories = (List<Category>) catRep.findAll();
model.addAttribute(“categories”, categories);

return new ModelAndView(“createProduct”, “newProduct”, new Product());
}

You have to add categories to the other method, or change the method to which the form:action points to.

And if I copy the category list in the CreateProductForm method? It will solve the problem of the duplicate key?

ok. the problem you stated was not getting the categories dropdown. now, you have duplicate key issue?

This is my controller
