Hi all,
I'm working with a MySQL legacy DB which was changed.
This was our previous Level table:
+-----------------+---------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------------+---------------+------+-----+---------+-------+
| level_name | varchar(20) | NO | PRI | | |
| instrument_name | varchar(20) | NO | PRI | | |
| available | enum('Y','N') | NO | | Y | |
| tablename | varchar(20) | YES | | NULL | |
+-----------------+---------------+------+-----+---------+-------+
This was the previous model class for the Level table:
class Level(models.Model):
level_name = models.CharField(primary_key=True, maxlength=60)
instrument_name = models.CharField(blank=False, maxlength=60)
available = models.TextField(blank=False)
tablename = models.CharField(blank=True, maxlength=60)
Because in the database the primary key was made of two fields, the
level_name and the instrument_name this wasn't working properly. So we
changed the table to:
+-----------------+---------------+------+-----+---------
+----------------+
| Field | Type | Null | Key | Default |
Extra |
+-----------------+---------------+------+-----+---------
+----------------+
| level_name | varchar(20) | NO | MUL |
| |
| instrument_name | varchar(20) | NO | |
| |
| available | enum('Y','N') | NO | | Y
| |
| tablename | varchar(20) | YES | | NULL
| |
| levelID | bigint(20) | NO | PRI | NULL |
auto_increment |
+-----------------+---------------+------+-----+---------
+----------------+
and the Level model class to (with the help of the inspectdb command):
class Level(models.Model):
level_name = models.CharField(unique=True, maxlength=60)
instrument_name = models.CharField(unique=True, maxlength=60)
available = models.TextField()
tablename = models.CharField(blank=True, maxlength=60)
levelID_id = models.AutoField(primary_key=True)
But now, when I try to do for example this:
def view_levels(request, orderby):
levels=Level.objects.all()
levellist=[]
for l in levels:
levellist.append({'levelname':l.level_name,
'instrname':l.instrument_name,
'available':l.available,
'tablename':l.tablename})
ordering='Instrument Name'
return render_to_response('view_levels.html',
{'levellist':levellist, 'ordering':ordering})
It gives me this error:
Exception Type: OperationalError
Exception Value: (1054, "Unknown column 'Level.levelID_id' in 'field
list'")
Exception Location: /nobackup/reis/Python/lib/python2.5/site-packages/
MySQLdb/connections.py in defaulterrorhandler, line 35
What is happening here?
Thanks for your time!
Ana
