Re: Why isn't user.photo being saved in UpdateView?

That's good

I solved the problem after digging around in the Django Forms related to ImageFields and FileFields.  I needed to add the <form enctype="multipart/form-data"> attribute in order for Django to process forms that contain ImageFields and/or FileFields.

#user_form.html

{% extends "base.html" %}
{% load crispy_forms_tags %}


{% block title %}{{ user.username }}{% endblock %}


{% block content %}
<div class="container">
  <h1>{{ user.username }}</h1>
  <form enctype="multipart/form-data" class="form-horizontal" method="post" action="{% url 'users:update' %}">
    {% csrf_token %}
    {{ form|crispy }}
    <div class="control-group">
      <div class="controls">
        <button type="submit" class="btn btn-primary">Update</button>
      </div>
    </div>
  </form>
</div>
{% endblock %}

For some reason, the updateview will save all of the other user fields (and update them if changed) to the database.  Do I need to handle the user.photo field differently? 

# views.py
class UserUpdateView(LoginRequiredMixin, UpdateView):

    model = User
    fields = ["name", "photo", "city", "experience", "domain", "bio"]

    def get_success_url(self):
        return reverse("users:detail", kwargs={"username": self.request.user.username})

    def get_object(self):
        return User.objects.get(username=self.request.user.username)

user_update_view = UserUpdateView.as_view()

The form:

# form.py
from django.contrib.auth import get_user_model, forms
from django.core.exceptions import ValidationError
from django.utils.translation import ugettext_lazy as _


User = get_user_model()

class UserChangeForm(forms.UserChangeForm):

    class Meta(forms.UserChangeForm.Meta):
        model = User

It does save the photo though in the Admin.

# admin.py
from django.contrib import admin
from django.contrib.auth import admin as auth_admin
from django.contrib.auth import get_user_model

from lexpy.users.forms import UserChangeForm, UserCreationForm

User = get_user_model()

@admin.register(User)
class UserAdmin(auth_admin.UserAdmin):


    form = UserChangeForm
    add_form = UserCreationForm
    fieldsets = (("User", {"fields": ("name", "photo", "height_field", "width_field",
            "city", "experience", "domain", "bio")}),) + auth_admin.UserAdmin.fieldsets
    list_display = ["username", "name", "is_superuser"]
    search_fields = ["name"]

Enter code here...
