Flask - how do I combine Flask-WTF and Flask-SQLAlchemy to edit db models?
Please refer to the wtforms documentation:
http://wtforms.simplecodes.com/docs/0.6/forms.html#wtforms.form.Form
You pass in the "obj" as argument. This will bind the model properties to the form fields to provide the default values:
@app.route('/person/edit/<id>/', methods=['GET', 'POST'])def edit_person(id): person = Person.query.get_or_404(id) form = PersonForm(obj=person) if form.validate_on_submit(): form.populate_obj(person)Notice also the "populate_obj" method. This is a handy shortcut which will bind the form values to the model properties (only those fields you have defined in your form, so quite safe to use).
