I am passing form variable from controller that contain field of type list. How to set user entered value at particular index of list. Below is my code:
@Data
public class TestForm {
public List<TestInfo> testInfo = new ArrayList<TestInfo>();
public static class TestInfo {
public String testName;
public long testId;
}
}
public Result testRoute() {
Form<TestForm> form = Form.form(TestForm.class);
return ok(test.render(form));
}
public Result postRoute() {
Form<TestForm> form = Form.form(TestForm.class).bindFromRequest();
TestForm tf = form.get();
System.out.println(tf.testInfo); // getting empty list
return ok(tf.testInfo.get(0).testName);
}
}
@(tests : Form[views.forms.school.TestForm])
@import helper._
<html>
<body>
<form action="@routes.CustomController.postRoute" method="Post">
<input type="text" name=tests("testInfo")(0).testName value="1"/>
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>
Here i have a TestForm that contains list of type TestInfo. TestInfo contains two field testName, and testId. And i am passing Form of type TestForm to scala template and there i want to set values of testName and testId based on user entered value and and i am binding this form inside controller whenever user press submit. but inside controller i am getting empty value.
I think you want to use the repeat helper in your view. The code would be something like below(although be aware I haven't actually tested this)
