How to store all form input in a dictionary?

[ledell]

I am wondering if there's a simple way to store all user input in a dictionary? The only way I see it do it is to use name='foo' and then that input is available q.app.foo. I would love to store all the input in a dictionary, like: input_values = {'foo1' : 'val1', 'foo2' : 'val2'} etc, so it's easier to work with, and I am not sure if there's a direct way to do that. Thanks!

Hi Erin.

q.args is an object of type Expando, which is just a fancy wrapper for python dict. This means

• It's already a dict and might be good enough for your use case as is.
• or it's possible to iterate over q.args and store them in your dict of choice for further processing.
• or reusing existing wave Expando utils (code below).

from h2o_wave import main, app, Q, ui, copy_expando, Expando, expando_to_dict

# Convert expando to dict.
expando_dict = expando_to_dict(copy_expando(q.args, Expando()))

The last approach is considered safest for most of the scenarios since mutating the newly created dict would not change the original Expando (q.args) as well.

@mturoci This is great! The expando_to_dict is exactly what I need, thanks.
