Ensuring Input Validity in Angular4 and Symfony3

Currently, I am utilizing angular 4 and symfony3. In my application, there is a textarea that is required. However, when I only press enter (code 13) in this textarea without entering any other character, the form gets submitted. How can I prevent this specific scenario from happening?

Below is the TypeScript code snippet:

createFormControls() {
    this.commentContent = new FormControl('', Validators.required);
}

Additionally, here is the symfony code section for reference:

/**
 * @var string
 *
 * @ORM\Column(name="content", type="text")
 *
 * @Assert\NotBlank(message="content is empty")
 *
 * @Serializer\Groups({"details"})
 */
private $content;

Answer №1

Form validation in model-driven forms is crucial for ensuring data integrity. Follow this example:

this.myForm = this.fb.group({
        'my_text_area':['', [Validators.required]]
    });
