javascript - Using a variable in req.body -


how use variable in req.body

example:

var names = {abc,xyz,cde};  var check = req.body.names[0];

or 

var names = {abc,xyz,cde};  var dummy = names[0];  var check = req.body.[dummy];

the first case throws error cannot read index 0 , second gives error of unexpected token '['. trying fetch form data who's names stored in array names.

ps: using node in end.

if use numeric indexes names must array. use bracket notation:

var names = [abc, xyz, cde]; var check = req.body[names[0]];

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
