I am writing a custom django model field which has serialize and unserialize operations, on unserialize, I am using the import_by_path to get the class and initialise an instance.
On the opposite, I need to serialize an instance to the database, in my case all I need to get the dot notation of the module.
What I am asking is, how I can, eg I have the datetime module
from datetime import datetime how to output datetime in dot notation to string "datetime.datetime" ?
Not entirely clear on what you're asking, but dot notation is equivalent to your above example in Python, for instance:
import datetime datetime.datetime is the same as
from datetime import datetime datetime I hope that makes sense, let me know if you have any more questions.
Here's a better example:
>>> import datetime >>> datetime <module 'datetime' from '/path/to/python'> >>> from datetime import datetime >>> datetime <type 'datetime.datetime'> Edit: After seeing the clarification, this should be done with the python inspect module. Specifically, if you're trying to get the module that defines a particular class:
import inspect import datetime inspect.getmodule(datetime).__name__ or
def dot_notation(your_module): return your_module.__module__ + "." + your_module.__class__.__name__ in a more general way, you can get the module
>>> from datetime import datetime >>> datetime.__module__+'.'+datetime.__class__.__name__ 'datetime.type' doesn't give me 'datetime.datetime'your_module, use the inspect module if it's a type or an object as in the first example.import inspect from datetime import datetime inspect.getmro(datetime)[0] That should return 'datetime.dateime'
