field.id_for_label why we use it
Labels and input why we used
why we use a label in forms and why we use input tag with it can’t get it properly.
Hello Yashu, the labels are used to define that the field is a name or about me or active. So, it is labelled for the frontend view so that we can distinguish to which field it is related. And the input field is used to assign the name value and id to the field and for matching that id with the id of the label.
And it is the way we use Django with HTML. We need to use field.id_for_label to get the label for the field.
