Answer 1

I solved a similar error I got when trying to save a form to a database. "Report() got an unexpected keyword argument 'summary'"

The problem was that the field names in models.py and forms.py didn't match.

In the class Report in models.py the name of the field was "summary_input", but in forms.py it was named "summary", so I changed the variable name in forms to match the one in models.

# models.py
class Report(models.Model):
    summary_input = models.TextField()

# forms.py
class ReportForm(forms.Form):
    summary = forms.CharField(widget=forms.widgets.Textarea)
    # changed to 
    # summary_input = forms.CharField(widget=forms.widgets.Textarea)
