Serialize complex python objects with multiple classes and lists to JSON -


i trying serialize complex python object multiple nested objects , lists. problem encountered described here: python serialize objects list json

now, have objects, lets say:

class a:     id = 0     objects_b = []     objects_c = []  class b:     id = 0  class c:     id = 0  = a() b = b() c = c() a.objects_b = [b] a.objects_c = [c]

i don't want add custom methods each new class add structure. there way make unified serialization method handle each new class no matter how included, in list or parameter? method use object type great, tolerate subclassing objects general type too. trying figure last hour , going little crazy, ready create own serialization method without using json lib, thats seems much...

json can serialize simple types (strings, dicts, lists etc). doesn't know how deal python objects.

so if want serialize objects, there no way around defining own serialization of classes these objects belong to. can use json library (read default) produce serialization of object, have own application-specific (or @ least python-specific) extension of json , might use that's python-specific, such pickle, works out of box. people use json because it's simple, readable , language-agnostic. if define own protocol extension json in order serialize python objects, there isn't reason use json in first place.

writing own object serialization hard. think detecting cycles, writing serializers every object might happen live in object graph (even if it's simple python datetime), , on.

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
