SQL 'Select/Explain' crashes because of redundant params substitution (fix provided)

When I click on Select or Explain SQL panel I get following error:

  File "/usr/lib/python2.6/dist-packages/django/core/handlers/base.py", line 115, in get_response
    response = callback(request, *callback_args, **callback_kwargs)

    return view_func(*args, **kwargs)

    self.cursor, sql, self._quote_params(params)),

    return cursor._last_executed.decode('utf-8')

  File "/usr/lib/python2.6/dist-packages/django/db/backends/mysql/base.py", line 150, in __getattr__
    return getattr(self.cursor, attr)
AttributeError: 'Cursor' object has no attribute '_last_executed'
 {middleware.py:process_exception():42}

After a bit of debugging I found that DebugToolbar is trying to substitute params to Select / Explain query - but this is wrong - parameters are already substituted because query is read from form.cleaned_data.

Fix:

• See debug_toolbar/views.py.
• Replace params = form.cleaned_data['params'] with params = () in sql_select(), sql_explain() and probably even in sql_profile() (haven't tested)

The main issue is that the Form uses sql instead of raw_sql + everything which follows on that. The error I get is:

TypeError: not all arguments converted during string formatting

which is also a result of not interpolating quries properly.

#417 should fix it.
