wtforms

问题 I am creating blog posts and have so far done it with a normal html form. One funky think I was doing was running javascript onclick and setting a hidden variable in the form with extra data from the page. This was passed to the server just fine and gotten with request.form. Now I want to use wtf.quick_form for the entering of blog posts. qtf.quick_form works great for simple things, but now I need to run some javascript on click and then set a form variable. At the server, I need to retrieve

问题 I have some Flask-SQLAlchemy models and Flask-WTF forms generated with wtforms_alchemy to represent them. I implemented a method on each model to update its attributes from a form's data. For each new model and field I have to update these methods, which is annoying. Is there a way to make this more automatic, or a a feature in the libraries I'm using that I'm missing? def edit_car(car_id): form = CarForm(request.form) if form.is_valid(): car = Car.query.get_or_404(car_id) car.from_form(form)

问题 Is there a way to pass "onclick" onto a WTForm field? I'd like to enable/disable a field depending on whether a WTF checkbox is selected. But the HTML from WTForms does not create or have an "onclick" parameter.

问题 I am developing a web page that reads JSON and presents it in a form using WTForms-JSON. When I submit the form, form.data isn't updated.
