Django __init__() got an unexpected keyword argument 'user'

Question

Im trying to build a password reset system using the default django libraries. The problem is after trying to enter the site which is for changing it (PasswordChangeConfirm) this error trace appears.

Internal Server Error: /reset/confirm/MQ/atg5tq-aa6bcab1c34d1228cdd1970aaaa45252/

                      <div class="pw_space"></div>
                      <h6 class="mb-0">Repeat New Password</h6>
                      <div class="pw_space2"></div>
                      {% render_field form.new_password2 class="form-control" type="password" placeholder="Repeat New Password" data-form-field="password"%}
                      {{form.errors}}
                      <div class="pw_space2"></div>
                      <button style="background-color:#7231aa; border:#7231aa; color:white;" class="btn btn-secondary " type="submit">Change Password</button>
                      <a style="background-color:#7231aa; border:#7231aa; color:white;" class="btn btn-secondary " target="__blank" href="{% url 'home:profilesettings' %}">Cancel</a>
                </form>

Im using widget tweaks to render the form but I guess thats not the problem because for other things this works.

Answer 1

Your password_reset_view inherits from PasswordResetConfirmView [Django docs], this view normally uses the form SetPasswordForm which takes the user as an argument (because it needs to set the users password), the problem is that your form CaptchaPasswordResetForm instead inherits from PasswordResetForm (incorrect) and hence you get an error. You should update your form class to inherit correctly:

from django.contrib.auth.forms import SetPasswordForm


class CaptchaPasswordResetForm(SetPasswordForm):
    ...
