Question

We have an api that consumes a around 50 to 100 query params. Currently the handler takes all of the params and sets them as attributes in a Meta object. Something like this

meta = Meta()
meta.param1 = param.get('param1', 'somedefault')
meta.param2 = param.get('param2', 'someotherdefault')

and so on. My question is, is there a better way to handle this than just a loooong list of assigns in the handler? My current idea is to just break it out into a helper function.

meta = self.get_meta(param)

Any other ideas?

(updated my example)

Answer 1

PARAMETERS = [
    'param1',
    'param2',
    # ...
]

meta = Meta()
for name in PARAMETERS:
    setattr(meta, name, param[name])

Based on your comment…

DEFAULTS = {
    'param1': 1,
    'param2': 'something',
}
meta = Meta()
for name, value in DEFAULTS.items():
    setattr(meta, name, param.get(name, value))
