Just for Django ORM you can pass parameters as a dictionary:

field_name = "status"
value = "joined"

filter_params = {
    field_name: value
}

model.objects.filter(**filter_params)

or just:

field_name = "status"
value = "joined"

model.objects.filter(**{field_name: value})

See this page for more details on unpacking a dictionary.

Try this

field_name = "status" 
value = "joined"

exec(f'{field_name} = "{value}"')

exec could be very unsafe. There is a better way by using dict unpacking

locals()[field_name] = value will create the variable without issues

@SardorbekImomaliev agree, but that's one solution
