Django 1.6.5 - "invalid literal for int() with base 10" in regirstration form

Question

I'm trying to implement a registration form but I get the following error:

invalid literal for int() with base 10:'alex'

I implemented it before and it worked well! But now it does not! My form contains an 'ImageField' and I followed the this and this docs and tutorials. I removed the Imagefield but the error remained! I read the similar question on SO but They didn't solve the problem.

The error occurs in the username field.

thanks for any comments.

my form.py is:

class RegisterationForm(ModelForm):
    # user name
    user_name = forms.CharField(max_length=32, label="Username account")
    # password
    password = forms.CharField(label='Password', widget=forms.PasswordInput(render_value=False))
    re_password = forms.CharField(label='Repeat Password', widget=forms.PasswordInput(render_value=False))
    # email
    email = forms.EmailField(label='Email Address')

    class Meta:
        model = WebsiteUser
        exclude = ('user', )

    def clean_user_name(self):
        user_name = self.cleaned_data['user_name']
        try:
            User.objects.get(username=user_name)
        except User.DoesNotExist:
            return user_name
        raise forms.ValidationError(u'UserName Error')


    def clean(self):
        password = self.cleaned_data['password']
        password1 = self.cleaned_data['re_password']
        if password != password1:
            raise forms.ValidationError(u'Passwords are not equal')
        return self.cleaned_data

and my view.py responsible for my register.html:

def register_view(request):
    if request.user.is_authenticated():
        return HttpResponseRedirect('/profile/')
    if request.method == 'POST':
        form = RegisterationForm(request.POST, request.FILES)
        if form.is_valid():
            user = User.objects.create_user(username=form.cleaned_data['user_name'],
                                            password=form.cleaned_data['password'],
                                            email=form.cleaned_data['email'])
            user.save()

            return HttpResponseRedirect('/profile/')
        else:
            return render_to_response('register.html', {'form': form}, context_instance=RequestContext(request))
    else:
        form = RegisterationForm()
        context = {'form': form}
        return render_to_response('register.html', context, context_instance=RequestContext(request))

and finally my register.html:

{% extends 'bases/home_base.html' %}
{% block content %}
    <form method="POST" action="">
        {% csrf_token %}
        {% if form.errors %}
            <p>
                Fix the errors!
            </p>
        {% endif %}
        <div id="register_div">    
            {% comment %} User Name {% endcomment %}
            {% if form.user_name.errors %}<p>{{ form.user_name.error_messages }}</p>{% endif %}
            <p><label for="user_name">User Name:</label></p>

            <p>{{ form.user_name }}</p>


            {% comment %} password {% endcomment %}
            {% if form.password.errors %}<p>{{ form.password.error_messages }}</p>{% endif %}
            <p><label for="password">password:</label></p>

            <p>{{ form.password }}</p>

            {% comment %} re_password {% endcomment %}
            {% if form.re_password.errors %}<p>{{ form.re_password.error_messages }}</p>{% endif %}
            <p><label for="re_password">re_password:</label></p>

            <p>{{ form.re_password }}</p>

            {% comment %} email {% endcomment %}
            {% if form.email.errors %}<p>{{ form.email.error_messages }}</p>{% endif %}
            <p><label for="email">email:</label></p>

            <p>{{ form.email }}</p>
        </div>
        <input type="submit"/>
    </form>

{% endblock %}

UPDATE

my model.py:

class WebsiteUser(models.Model):
    # username
    user_name = models.OneToOneField(User, max_length=32)
    # birth day
    birth_day = models.DateField()
    # email address
    email = models.EmailField(max_length=50)
    # watched movies
    watched_movies = models.ManyToManyField(Movie, related_name='watched', blank=True, null=True)
    # rated movies
    rated_movies = models.ManyToManyField(Movie, related_name='rated', blank=True, null=True)
    # recent movies
    recent_movies = []

    def __unicode__(self):
        return " ".join([self.first_name, self.last_name])

Suggest posting the line causing the error and a stack trace. — arocks, Jul 09 '14 at 10:31

WebsiteUser.user_name is OneToOneField, thus it stores a value of primary key of the related object. You're trying to store a username there instead, that won't work.

the problem is with my form validation! – Hadi Jul 09 '14 at 12:57

so what?! `user_name` is ForeignKey, that means it's an integer field in DB. So if you validate your **ModelForm** then it validates it against the model, not the type you say in form. – yedpodtrzitko Jul 09 '14 at 13:34
