I was trying to change my templates by adding 2 buttons for the forms and got this error. It displays the two buttons but everytime I click one it doesn't submit correctly. I want to make the is_doctor field in the modal set to false or true depending on the button click.

views.py

from django.shortcuts import redirect, render
from .forms import PickUserType, SignUpForm, UserProfileForm
from django.contrib.auth import login, authenticate

from formtools.wizard.views import SessionWizardView

def show_message_form_condition(wizard):
    # try to get the cleaned data of step 1
    cleaned_data = wizard.get_cleaned_data_for_step('0') or {}
    # check if the field isDoctor was checked.
    return cleaned_data.get('is_doctor')== False

def process_data(form_list):
    form_data = [form.cleaned_data for form in form_list]
    print(form_data)
    return form_data

WIZARD_FORMS = [("0", PickUserType),
                ("1" , SignUpForm),
            ]
TEMPLATES = {"0": "pickUserType.html",
             "1": "createUser.html"}

class ContactWizard(SessionWizardView):

    def done(self, form_list, **kwargs):
        process_data(form_list)
        return redirect('home')

    def get_template_names(self):
        return [TEMPLATES[self.steps.current]]

CodePudding user response：

You are using a formwizard and it seems that you are missing the wizard management formdata in your html form.

{% block content %}

  <form method="post">
    {% csrf_token %}
    <!-- A formwizard needs this form -->
    {{ wizard.management_form }}


    {% for field in form %}
      <p>
        {{ field.label_tag }}<br>
        {{ field }}
        {% if field.help_text %}
          <small style="color: grey">{{ field.help_text }}</small>
        {% endif %}
        {% for error in field.errors %}
          <p style="color: red">{{ error }}</p>
        {% endfor %}
      </p>
    {% endfor %}
    <button type="submit">Sign up</button>
