in my Database (psql) I've got a table named `offers_offer` and inside that there is an column named `offer_name`, which is wrong, because it should actually be just `name`. I don't know why it has this name, but due to this I can't load any fixtures or create a new object, because I always receive the error that `name` wasn't found (obviously). 

Now my model looks like this: 

```
class Offer(models.Model):
   name = models.CharField(default="", verbose_name='Offer Name', blank=False, max_length=255)
   (some other fields...)

```

and my ONLY initial migration looks like this:

```
from __future__ import unicode_literals

from django.db import migrations, models
import django.utils.timezone

class Migration(migrations.Migration):

    initial = True

    dependencies = [
        ('crm', '0007_make_gender_mandatory'),
    ]

    operations = [
        migrations.CreateModel(
            name='Offer',
            fields=[
                ('name', models.CharField(default='', max_length=255, verbose_name='Offer Name')),
                (every other field...)
                ],
            options={
                (some options...)
            },
        ),
    ]

```

So I don't really know why it's named `offer_name` in my db, while this was created to have `name` as field name. 

Anyway I tried to fix that by making a new migration like:

```
from __future__ import unicode_literals

from django.db import migrations, models

class Migration(migrations.Migration):

    dependencies = [
        ('offers', '0001_initial'),
    ]

    operations = [
        migrations.AlterField(
            model_name='offer',
            name='offer_name',
            field=models.CharField(default='', db_column=b'offer_name', max_length=255, verbose_name='Offer Name'),
        ),
        migrations.RenameField(
            model_name='offer',
            old_name='offer_name',
            new_name='name',
        ),
    ]

```

But if I do that, I just get a FieldDoesNotExist Error which states me that `django.core.exceptions.FieldDoesNotExist: Offer has no field named 'offer_name'`

So does someone know a good way to fix that?
