I having a error "expected string or buffer" when submit to upload avatar when edit profile. Can't figure out what is the problem..

I've setup a small project with your code (and small modifications) using django 1.7 and python 2.7.8 (it's important to provide that infos).

I did not reproduce the error.

I describe below what I changed or can be changed:

 

Model:

class MyProfile(models.Model):
    user = models.ForeignKey(User)
    dob = models.DateField(null=True, blank=True)
    address = models.CharField(max_length=100, blank=True)
    contact = models.CharField(max_length=50, blank=True)
    bio = models.TextField(blank=True)
    avatar_url = FileField(_("Avatar"), max_length=200, format="Image", upload_to='user/avatar', blank=True)
    banner_url = FileField(_("Cover"), max_length=200, format="Image", upload_to='user/cover', blank=True)
    created = models.DateTimeField(auto_now_add=True)
    last_modified = models.DateTimeField(auto_now=True)

- There is no "format" parameter in FileField constructor. 

- it's better to stay consistent regarding the model fields and use models.FileField instead of FileField alone. If FileField is a custom class, it should have another name.

- User model is referenced directly. You can live with that. It can break in some situations cf. https://docs.djangoproject.com/en/1.7/topics/auth/customizing/#referencing-the-user-model

 

Forms:

class UserModelForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ('first_name', 'last_name', 'email')
        widgets = {
            'email': forms.TextInput(attrs={'readonly':'readonly'}),
        }


class UserProfileModelForm(forms.ModelForm):
    dob = forms.DateField(widget=forms.DateInput(format = '%d/%m/%Y'), 
                               input_formats=('%d/%m/%Y',), 
                               required=True, help_text='dd/mm/yyyy')
    avatar_url = forms.FileField()

    class Meta:
        model = MyProfile
        fields = ('dob', 'address', 'contact', 'bio', 'avatar_url')



Views:

def editProfileView(request, template="controlpanel/cp_edit_profile.html"):

    myprofiles = MyProfile.objects.all()
    myprofile = get_object_or_404(myprofiles, user=request.user)

    if request.method == "POST":
        form = UserProfileModelForm(request.POST, request.FILES, instance=myprofile)
        userForm = UserModelForm(request.POST, request.FILES, instance=request.user)

        if form.is_valid() and userForm.is_valid():
            user = userForm.save()
            profile = form.save(commit = False)
            profile.user = user
            profile.save()


            info(request, _("Successfully Edit"))
    else:
        userForm = UserModelForm(instance=request.user)
        form = UserProfileModelForm(instance=myprofile)


    context = {"cpprofile": myprofile, 'userForm':userForm, 'form':form}

    return render(request, template, context)

Template:

<form method="post" action="/editprofile" enctype="multipart/form-data">
            <fieldset>
            <legend>{{ title }}</legend>
            {% fields_for userForm %}
            {% fields_for form %}
            <div class="form-actions">
                {% block account_form_actions %}
                <input class="btn btn-primary btn-lg pull-right" type="submit" value="Submit">
                {% endblock %}
            </div>
            </fieldset>
</form>




I don't know {% fields_for %} tag. I used {{ userForm.as_ul }} instead.

If you are interested, I can push the code online.
