The `has_results` method of the `Query` class (in
`django/db/models/sql/query.py`), passes the `using` argument to the
`exists()` method:
```python
def has_results(self, using):
q = self.exists(using)
compiler = q.get_compiler(using=using)
return compiler.has_results()
```
but the signature of the `exists` method does not accept an argument to
select the db connection. It only accepts an argument to limit the rows it
should fetch:
```python
def exists(self, limit=True):
# ... snip ...
```
