How to Reference Variable From Different View (Django)

I would like to use a variable outside of the function in which it was defined. I have only ever passed data to different templates and have not had to reference that data afterwards so I am unsure as to how I should proceed.

views.py

def new_opportunity_company_id(request):
    company = request.GET.get('selected_company')
    company_obj = cwObj.get_company(company)
    company_id = company_obj[0]['id']
    return company_id


def new_opportunity_location(request):
    for company_id in new_opportunity_company_id(request):
        locations = cwObj.get_sites(company_id)
        context = {'locations': locations}
    return render(request, 'website/new_opportunity_location.html', context)

Any help would be greatly appreciated, I am still new to Django/Python. Thanks!

Which variable are you referring to in this example? Also note your code is assuming that company_obj[0]['id'] is a list as your trying to iterate it in new_opportunity_location. The times you should be attempting to access a variable outside of a function scope do not come that often. They would either be a global, class variable or a function parameter thats passed. Other then that you may need to reconsider your approach to make your code more straight forward.

Following up to your comment...

 def new_opportunity_location(request):
        company = request.GET.get('selected_company')
        company_obj = cwObj.get_company(company)
        company_id = company_obj[0]['id']
        locations = cwObj.get_sites(company_id)
        context = {'locations': locations}

        return render(request, 'website/new_opportunity_location.html', context)

I imagine you had something close to this? A Reference before assignment means your trying to access a variable that hasn't been set yet. So this probably means that line company_id = company_obj[0]['id'] returned none and then trying to use it in cwObj.get_sites(company_id) caused a reference error
