I have a Django application. But i can't an error that i have been struggling with for some time now.
Exception Value: 'tuple' object has no attribute 'get'
Exception Location: /Library/Python/2.7/site-packages/django/middleware/clickjacking.py in process_response, line 30
And this is the traceback django provides me.
Traceback:
File "/Library/Python/2.7/site-packages/django/core/handlers/base.py" in get_response
201. response = middleware_method(request, response)
File "/Library/Python/2.7/site-packages/django/middleware/clickjacking.py" in process_response
30. if response.get('X-Frame-Options', None) is not None:
I have a hard time figuring out why this error occurs. How can i find out where that tuple is in my code?

The Python "AttributeError: 'tuple' object has no attribute" occurs when we access an attribute that doesn't exist on a tuple. To solve the error, use a list instead of a tuple to access a list method or correct the assignment.
It's simply because there is no attribute with the name you called, for that Object. This means that you got the error when the "module" does not contain the method you are calling.
The “TypeError: 'tuple' object is not callable” error is raised when you try to call a tuple as a function. This can happen if you use the wrong syntax to access an item from a tuple or if you forget to separate two tuples with a comma. Make sure when you access items from a tuple you use square brackets.
AttributeError can be defined as an error that is raised when an attribute reference or assignment fails. For example, if we take a variable x we are assigned a value of 10. In this process suppose we want to append another value to that variable. It's not possible.
If we call the get () method on the tuple value, Python will raise an AttributeError: ‘tuple’ object has no attribute ‘get’. The error can also happen if you have a method which returns an tuple instead of a dictionary. Let us take a simple example to reproduce this error.
A tuple is a sequence of immutable Python objects. Tuples are sequences, just like lists. The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets. I am also new to Python so I might be on the wrong track but maybe vf1 should not be of type tuple.
This error occurs when attempting to access the values of a tuple incorrectly. Functions that return multiple variables will output the results in a tuple, so we cannot use dot-access to retrieve the values. For example, let's create a simple function that returns two values:
The solution shows that tuple values need to be unpacked and assigned to variables before directly accessing them. Note that we can unpack our function output straight into add, mult, and div, without having to use results as a go-between: This article contains a few more examples of unpacking functions and lists.
You are returning a tuple here:
elif retailer_pk:
return (request, 'page-retailer-single.html', {
"products": products,
"sorting": filt["sorting"],
"filtering": filt["filtering"],
"retailer": retailer,
})
Did you forget to add render there perhaps:
elif retailer_pk:
return render(request, 'page-retailer-single.html', {
"products": products,
"sorting": filt["sorting"],
"filtering": filt["filtering"],
"retailer": retailer,
})
There is an extra comma "," at the end of return function in views.py
return render(request, 'index.html',{}), #incorrect
return render(request, 'index.html',{}) #correct
