I downloaded [django-wysiwyg-redactor](https://pypi.python.org/pypi/django-wysiwyg-redactor/)

and followed instructions about how to use it.
But when I choose image to upload it doesn't upload. There is no errors.
What's wrong with it?

Here is my article model:
from django.db import models
from redactor.fields import RedactorField

Create your models here.
========================

```
class Article(models.Model):
    class Meta():
        db_table = 'article'

    article_title = models.CharField(max_length=200)
    article_text = RedactorField(
        verbose_name=u'Text',
        redactor_options={'lang': 'en', 'focus': 'true'},
        upload_to='tmp/',
        allow_file_upload=True,
        allow_image_upload=True
    )
    article_date = models.DateTimeField()
    article_likes = models.IntegerField(default=0)

```

and `admin.py`

```
from django.contrib import admin
from redactor.widgets import RedactorEditor
from article.models import Article
from django import forms

class EntryAdminForm(forms.ModelForm):
    class Meta:
        model = Article
        widgets = {
           'article_text': RedactorEditor(),
        }

class EntryAdmin(admin.ModelAdmin):
    form = EntryAdminForm
    fields = ['article_title', 'article_text', 'article_date']

admin.site.register(Article, EntryAdmin)

```

Last code line: `admin.site.register(Article, EntryAdmin)` is a little changed, because as instruction says, it must be `admin.site.register(EntryAdminForm, EntryAdmin)`, but in ths case, there is an error:`'ModelFormMetaclass' object is not iterable`
