How to store python objects with complex data fields in data base in Django?
django, python, serialization
Solution
You may want to look at django-picklefield.
django-picklefield provides an implementation of a pickled object field. Such fields can contain any picklable objects.
Basically, this will take any Python object, save a pickled representation of it, and you can re-create it as the same exact object after pulling the pickled representation right out of the database.
You may want to create a model object NK_Automata that stores each of those attributes in a picklefield, then create a method to recreate the actual class object w/ all attributes. I can't assure you that the full class would be picklable, but it may ever be possible to store the whole NK_Automata class instance in a field.
Problem
I have a python class with comlex data structures. It has nested lists and dicts of objects and plain data. ``` class NK_Automata(object): def __init__(self,p_N=5,p_K=5,p_functionsList=None,p_linksList=None): self.N=p_N self.K=p_K if p_functionsList==None: p_functionsList=[] else: self.functionsList= p_functionsList #list of BinFunction objects if p_linksList==None: self.linksList=[] else: self.linksList=p_linksList #list of lists of integers self.ordinalNumber=-1 self.stateSpan={} #stateSpan: {currentStateNumber: nextStateNumber,...} self.stateList=[] #list of integers self.attractorDict={} #attractorDict: {attractorNumber:[size,basinSize],...} self.attractorStatesDict ={} #attractorStatesDict: {attractorStateNumber:[nextAttractorStateNumber,attractorStateWeight],...} ``` How should I store it in data base (sqlite3)? How to make a Django model for this object? Should I serialize the object? Upd Fixed default parameters as suggested
