AttributeError: type object 'Team' has no attribute '_meta'

Question

so I'm pretty new to Django and for the life of me can't seem to figure out what's going on here. I had a form working and showing up in a webpage, and I was able to get a database to be created and show up in SQL. However, when I tried to get the forms to save the information into the database, the fields I began testing with have disappeared and nothing is written to the database.

I also keep getting this error : AttributeError: type object 'Team' has no attribute '_meta'

traceback:

Solution

The problem is in your forms.py. See you have this model import:

from .models import Team

And then you define the Team form shadowing the imported model:

class Team(forms.Form):

Then, when you use model = Team inside the TeamForm it would actually use the Team form reference and not the imported model.

---

One way to fix that is to alias your import statement:

from .models import Team as TeamModel

and then use it to set the model on the model form:

class TeamForm(ModelForm):
    class Meta:
        model = TeamModel
        fields = ['team_number', 'team_name']

Thanks! That worked to solve my Attribute Error, now I've just got to figure out how to get it to write to my database
