utils - unknown column in field list django mysql

"Unknown column 'user_id' error in django view (3)

  1. The user_id field is the FK reference from Idea to User. It looks like you've changed your model, and not updated your database, then you'll have this kind of problem.

    Drop the old table, rerun syncdb.

  2. Your model tables get an id field by default. You can call it id in your queries. You can also use the synonym of pk.

    If you define your own primary key field you, you don't get the automatic id field. But you can still use pk to refer to the Primary Key.

I'm having an error where I am not sure what caused it.

Here is the error:

Exception Type:     OperationalError
Exception Value:    
(1054, "Unknown column 'user_id' in 'field list'")

Does anyone know why I am getting this error? I can't figure it out. Everything seems to be fine.

My view code is below:

if "login" in request.session:
    t = request.POST.get('title', '')
    d = request.POST.get('description', '')
    fid = request.session["login"]
    fuser = User.objects.get(id=fid)
    i = Idea(user=fuser, title=t, description=d, num_votes=1)
    return HttpResponse("true", mimetype="text/plain")
    return HttpResponse("false", mimetype="text/plain")

I appreciate any help! Thanks!

Edit: Also a side question. Do I use objects.get(id= or objects.get(pk= ? If I use a primary key, do I need to declare an id field or an index in the model?

Edit: Here are the relevant models:

class User (models.Model):
    first_name = models.CharField(max_length=200)
    last_name = models.CharField(max_length=200)
    email = models.CharField(max_length=200)
    password = models.CharField(max_length=200)

class Idea (models.Model):
    user = models.ForeignKey(User)
    title = models.CharField(max_length=200)
    description = models.CharField(max_length=255)
    num_votes = models.IntegerField()

Yes, I dropped the tables and it all worked great. However, you have to actually go into the database and DROP them. "manage.py flush" or "manage.py reset appname" won't do it by themselves.

Can't save django object to mysql (ManyToManyField)

Have you tried saving the art and eusr items first -- ie:


Before calling cl.save()
