Accessing the Value of a Django Queryset using a secondary list of column names

Question

Im trying to avoid a hardcoding situation in my code

if have a Customer queryset for example the columns are (name,phone,email….)

so if I do

customer = Customer.objects.get(name = 'bbc')

# to get the values of each field I need to do

customer.name

customer.phone

customer.email

……

to avoid having to do this as I need to compare each field in an If statement to make a not of any changes from a form I made a list that contains the column name

Example of the if statement

if customer.name == some variable or customer.email == some vairiable …..

I made a list that contains the column name to avoid this issue

list = ['name', 'phone' , 'email']

when I do this

for loop 

if customer.list[i] == some variable

I get an error customer doesn't contain attribute list

how can I get around this issue

thanks in advance

You can use the getattr function which is built into python. You need to pass the object and attribute name as string to use it. Like this:

if any(getattr(customer, li) == some_variable for li in mylist):
