I'm trying to create an edit page for an existing model (already saved to db). The form object expects a multidict instance to populate its fields. This is what I have:
# the model - assumes Flask-SQLAlchemy
from flaskext.sqlalchemy import SQLAlchemy
db = SQLAlchemyd(app)
class Person(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80), unique=True)
def __init__(self, name=name):
self.name = name
# the form - assumes Flask-WTF ext.
from flaskext.wtf import Form, TextField, Required, BooleanField
class PersonForm(Form):
name = TextField('name')
## the view
@app.route('/person/edit/<id>/', methods=['GET', 'POST'])
def edit_person(id):
person = Person.query.get(id)
if person:
form = PersonForm(person) #<-- raises error
return render_template('edit_person.html', form=form)
I could assign each field in the form to each field of the model (form.data['name'] = person.name, etc...)
, but that seems redundant for large models. Is there any shortcut I'm missing? thanks.
