Okay, I've tried searching for this for quite some time. Can I not pass args and kwargs to a view in a django app? Do I necessarily have to define each keyword argument independently?
For example,
#views.py
def someview(request, *args, **kwargs):
...
And while calling the view,
response = someview(request,locals())
I can't seem to be able to do that. Instead, I have to do:
#views.py
def someview(request, somekey = None):
...
Any reasons why?
If it's keyword arguments you want to pass into your view, the proper syntax is:
def view(request, *args, **kwargs):
pass
my_kwargs = dict(
hello='world',
star='wars'
)
response = view(request, **my_kwargs)
thus, if locals() are keyword arguments, you pass in **locals(). I personally wouldn't use something implicit like locals()
*args and **kwargs are used to pass a variable number of arguments to a function. Single asterisk is used for non-keyworded arguments and double for keyworded argument.
For example:
def any_funtion(*args, **kwargs):
//some code
any_function(1,arg1="hey",arg2="bro")
In this, the first one is a simple (non-keyworded) argument and the other two are keyworded arguments;
The problem is that locals() returns a dictionary. If you want to use **kwargs you will need to unpack locals:
response = someview(request,**locals())
When you use it like response = someview(request,locals()) you are in fact passing a dictionary as an argument:
response = someview(request, {'a': 1, 'b': 2, ..})
But when you use **locals() you are using it like this:
response = someview(request, a=1, b=2, ..})
You might want to take a look at Unpacking Argument Lists
