th:field gives default value as 0 in input field

Question

I have a problem as mentioned in the title.
The input field is of type number.
The th:field refers to an int attribute in the database.
I want my placeholder to be visible instead of the default 0 value.

<input id="courseCredits"  name="courseCredits" th:field="*{courseCredits}" class="form-control" placeholder="Course Credits" type="number" min="0" required autofocus/>

Answer 1

If you don't want the default of 0 you can't use an int. Instead use an Integer with null for empty.
