Working with forms

If we look at the structure of the form for new_user and edit_user, we can see that both forms are almost the same, with just a few differences. For example, the forms' action endpoints are different, as there are two extra fields for edit_user: _METHOD and old_password. To simplify, we can make one template to be used by both functions. Let's look at the steps:

  1. Create a template called src/views/users/form.html.tera, and insert the following lines:
    {% extends "template" %}
    {% block body %}
      <form accept-charset="UTF-8" action="{{ form_url }}"

        <fieldset>
        </fieldset>
      </form>
    {% endblock %}
  2. Next, let's add the title to the form by adding a legend tag. Put this inside the fieldset tag:
    <legend>{{ legend }}</legend>
  3. Under the legend tag,...
