Многоступенчатая форма в Джанго

Question

Я работал с нормальными хрустящими формами в Джанго.Я изменил форму на многошаговую форму, теперь отправка не работает.Поэтому, когда я нажимаю на кнопку «Отправить», данные не сохраняются в БД.Вот так выглядит обновленный шаблон: index.html index.html

<ul id="progressbar">
            <li class="active">Account Setup</li>
            <li>Social Profiles</li>
            <li>Personal Details</li>
          </ul>
            <!-- fieldsets -->
          <fieldset>
            <h2 class="fs-title">Help me know you better</h2>
            <h3 class="fs-subtitle">This is step 1</h3>
            {{ form.associate_image|as_crispy_field}}
            <input type="button" name="next" class="next action-button" value="Next" />
          </fieldset>
          <fieldset>
            <h2 class="fs-title">Social Profiles</h2>
            <h3 class="fs-subtitle">Your presence on the social network</h3>
            {{ form.title|as_crispy_field}}
            {{ form.client|as_crispy_field }}
            {{ form.lob|as_crispy_field }}
            <input type="button" name="previous" class="previous action-button" value="Previous" />
            <input type="button" name="next" class="next action-button" value="Next" />
          </fieldset>
          <fieldset>
            <h2 class="fs-title">Personal Details</h2>
            <h3 class="fs-subtitle">We will never sell it</h3>
            {{ form.gender|as_crispy_field }}
            {{ form.phone_number|as_crispy_field }}
            <textarea name="address" placeholder="Address"></textarea>
            <input type="button" name="previous" class="previous action-button" value="Previous" />
            <input type="submit" name="submit" id="submit-award" class="submit action-button" value="Submit" />
         </fieldset>

    associate_details = ldap.search(associate_id=associate_id)[0]
    details = UserDetails(
