Can you get the django form id from django template using id_fieldname?

I am using a model form that has 3 fields - name, country and city. My template looks like this-

<form method="post" id="personForm" data-cities-url="{% url 'ajax_load_cities' %}">
    
    {% csrf_token %}
        {{form}}
  
    <input type="submit" value="Submit">
</form>

Following this is a bit more jQuery code that fetches the id for the "country" field using a code like this -

$("#id_country").change(function ()....

Two things I need to mention here, no where in my code I have id_country except from this jQuery code. Also I haven't set the id attribute for the country field anywhere.

So my question is , is this a thing in django or in jQuery where you can get the id for a field using id_ in front of the field name?

I read the django documentation, haven't seen anything like this. What am I missing here?

Thanks for any input.

When one renders a Django form, it automatically renders an id attribute on the form fields. As you noticed this id is of the form id_<field-name>. This is noted in the documentation in the section Working with form templates:

Note that each form field has an ID attribute set to id_<field-name>

Hence you have an id as id_country because you have a form field named country. If you were to have a field named foo its id would be id_foo.
