Type-casting of session object in python, django

I would like to ask something about tyoe casting in python, Django. I have a CompanyReview object in session request.session['review_company_review'] and I would like to get this object. I have written the code below but I consider there should be a better way.

cr = CompanyReview()
cr = request.session['review_company_review']

Could you g开发者_开发百科ive me any idea how I can cast my session object to companyreview object ?

PS: I try to do cr = ComapnyReview(request.session['review_company_review']) but it didn't work.

Thanks

You don't need any type-casting in Python.

If you have saved that object to session doing like request.session['review_company_review'] = some_company_review_object, to retrieve that object you can just do:

cr = request.session['review_company_review']
