Saving an Object (Data persistence)

Question

I\'ve created an object like this:

company1.name = \'banana\' 
company1.value = 40

I would like to save this object. How can I do that?

You can use anycache to do the job for you. It considers all the details:

• It uses dill as backend, which extends the python pickle module to handle lambda and all the nice python features.
• It stores different objects to different files and reloads them properly.
• Limits cache size
• Allows cache clearing
• Allows sharing of objects between multiple runs
• Allows respect of input files which influence the result

Assuming you have a function myfunc which creates the instance:

from anycache import anycache

class Company(object):
    def __init__(self, name, value):
        self.name = name
        self.value = value

@anycache(cachedir='/path/to/your/cache')    
def myfunc(name, value)
    return Company(name, value)

Anycache calls myfunc at the first time and pickles the result to a file in cachedir using an unique identifier (depending on the function name and its arguments) as filename. On any consecutive run, the pickled object is loaded. If the cachedir is preserved between python runs, the pickled object is taken from the previous python run.
