Form validation with WTForms and SQLAlchemy autocomplete model with form data in Flask

I have a form that I have to validate and then save the data to a database. I have a model SQLAlchemy

called Campaign

that looks something like this:

from flask.ext.sqlalchemy import SQLAlchemy

db = SQLAlchemy()
class Campaign(db.Model):
    __tablename__ = 'campaigns'

    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50))
    priority = db.Column(db.SmallInteger)
    starts_at = db.Column(db.Date)
    ends_at = db.Column(db.Date)
    .... bla bla bla

      

        
        
        
      

    

Now I have a form WTForm

to validate as

from flask.ext.wtf import Form, TextField, IntegerField, DateField, Required, NumberRange
class CampaignForm(Form):

    def date_validation(form, field):
        #some validation on date

    name = TextField(validators=[Required()])
    priority = IntegerField(validators=[Required(), NumberRange(min=1,max=100)])
    start_date = DateField(validators=[Required(), date_validation])
    end_date = DateField(validators=[Required(), date_validation])
    ... bla bla bla

      

        
        
        
      

    

Now, to validate and save the form data, I can do something like this: view

code in Flask

class CampaignsView(MethodView):
    def post(self):
        """
        For creating a new campaign
        """
        form = CampaignForm(request.form)
        if form.validate():
            campaign = Campaign(form.name.data, form.priority.data, and so on )
            session.add(campaign)

      

        
        
        
      

    

Now the above code is silly because I have to hard-code each field name in the view. Is there any other way where I can populate my model fields with form fields? Thanks to
