Question: fragment of models.py

```
class Hardware_type(models.Model):
    type = models.CharField(blank = False, max_length = 50, verbose_name="Type")
    description = models.TextField(blank = True, verbose_name="Description")
    slug = models.SlugField(unique = True, max_length = 255, verbose_name = "Slug")

class Software_type(models.Model):
    type = models.CharField(blank = False, max_length = 50, verbose_name="Type")
    description = models.TextField(blank = True, verbose_name="Description")
    slug = models.SlugField(unique = True, max_length = 255, verbose_name = "Slug")

```

and now 

```
>>> sw = Software_type.objects.get(slug='unix')
>>> sw
<Software_type: Unix>
>>> hw = Hardware_type.objects.get(slug='printer')
Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: type object 'Hardware_type' has no attribute 'objects'

```

I can't see why this happens. Anyone can help me?

Edit:

sorry that did not sent all the code - **problem solved.**
in another class I had

```
hardware_type = models.ManyToManyField(Hardware_type, verbose_name="Hardware Type")

```

after change from hardware\_type to hw\_type - works fine 
I did not know that can cause this problem.

Answer: 
If you add a custom manager to a model then the default manager at `objects` will not be created. Either add it yourself in the class definition, or stick with using the custom manager.
it turned out that only began to work in django console,

Later I noticed that I have some old code in forms.py

```
class Hardware_type(forms.ModelForm):
    class Meta:
        model = Hardware_type

```

and thus it did not work, it was a bad day for naming classes, etc.
