Why variable is `None` in my case? - django

My code:
if not 'last_user_visit' in request.COOKIES:
response.set_cookie('last_user_visit', now)
last_visit = request.COOKIES.get('last_user_visit')
print last_visit
Why last_visit is None in my case?

Because you're setting it on the response, and reading it back from the request. The version in request won't be updated until the response has been sent to the client and the next request has been received.

You have to send response first like Daniel have suggested, you are setting cookie on response and then you have to return it. So that from that time, whenever a request will come it will be holding that cookie and you can access it. you can create function like this:
def cookie_setter(request):
'''Do your function task and create response object
'''
if not 'last_user_visit' in request.COOKIES:
response.set_cookie('last_user_visit', now)
return response

Why does this request return an empty string?

I have the following function which makes a get request to a url.
def fetch_data(session = None):
s = session or requests.Session()
url = 'http://www.moldelectrica.md/utils/load4.php'
response = s.get(url)
print response.status_code
data = response.text
return data
I expect to get a string back in the form.
169,26,0,19,36,151,9,647,26,15,0,0,0,0,0,150,7,27,-11,-27,-101,-19,-32,-78,-58,0,962,866,96,0,50.02
But instead I get an empty unicode string. The status code returned is 200.
I've looked at the request headers but nothing in them suggests that any headers will require being set manually. Cookies are used but I think the session object should handle that.
Figured it out. As I said this url provides data for a display so it wouldn't normally be visited directly. Usually it would be requested by the display page and that page would provide a cookie.
So the solution is to make a request to the display url then reuse the session and make another request to the data url.

Using postman to test POST request, how do I access the form-data inside the request?

I've been googling for a few hours, and I need help. I dont think I'm using the correct words. Anyhow, I'm using Claudia.JS to set up a POST request to my AWS Lambda function. Here's the basics of the function:
api.post('/leads', function (request) {
console.log(request);
return request;
});
When I use postman to test the post request, I'm returned the request object. Awesome. Then I try to pass form-data through. I set the key to 'username' and the value to 'this is the username'. This is what request.body is:
"body": "---------------------------
-019178618034620042564575\r\nContent-Disposition: form-data;
name=\"username\"\r\n\r\nthis is the username\r\n----------------------
------019178618034620042564575--\r\n",`
I thought I could return request.body.username... to key the value of username...but I'm missing something.
How do I access the form data in the request?
update: okay. The website is taking the form data, making a post request...this function is receiving the post request? still-- in postman...if I were to put my own JSON in...why can I not access request.body like... request.body.username?
You should try console.log(request.data) to see your request object, ie. in my own case I can see the content of my request's body.
Have a look at https://www.getpostman.com/docs/postman/scripts/postman_sandbox to see all the relevant information about your request.
I solved this by looking at the header set in postman. It was set to form-data instead of application/JSON. All gravy now.

Missing form data in request

I have following code
class MyClass(restful.Resource):
def get(self):
headers = {'Content-Type': 'text/html'}
return make_response(render_template('myfile.html'),200,headers)
def post(self):
session['CONSUMER_KEY']=request.form.get('consumer_key')
session['CONSUMER_SECRET']=request.form.get('consumer_secret')
render_template('myfile.html')
api.add_resource(MyClass,"/mag/",endpoint="mag")
I have written following test:
def mytest(self):
content_type={"Content-Type": "application / x - www - form - urlencoded","Content-Disposition": "form-data"}
response = self.client.post(
api.url_for(MyClass), data = json.dumps({'consumer_key':'testconsumerkey',
'consumer_secret':'testconsumersecret'}),
headers=content_type
)
The issue is form data is blank and thats the values are not getting set in session. When i debug i see that request.data is populated but request.form is an empty dictionary. Can someone suggest how I can send form data in a post request from a test
EDIT: Environment details
Python 2.7, Flask web framework, self.client is . I am using flask.ext.testing
You seem to be confused as to what the expected format for the post body should be. Should it be JSON data (which is what you send in the test case), or should it be in the application/x-www-form-urlencoded format (which is what you claim to send in the test case, and what the endpoint will read)?
If you wish to receive JSON data, you'll need to change the endpoint to read the data from request.get_json(). You'll also need to use application/json as the Content-Type header in the test case.
If you wish to receive urlencoded post data, then just simplify the test case by removing the Content-Type header and the json.dumps. Just pass the data dict to the data argument.

Django: Get cookie inside test case

I have a view that sets a cookie using response.set_cookie method. I would like to test if the cookie is being set in a TestCase.
According to docs, the cookie should be accessible in the client object, but client.cookies.items returns an empty list. The cookie is being correctly set in the browser.
Any ideas?
EDIT: adding test case
>>> response = self.client.get(url)
>>> self.client.cookies.items()
[]
The last statement returns an empty list.
You need to use the response's client instance:
response = self.client.get(url)
response.client.cookies.items()

Access raw_post_data in django test client

The title pretty much says it all: I use raw_post_data in a couple of views, and thus I need the test client to properly grant access to it.
I have copied the raw_post_data string, from a mock request, passed it to json.loads(), and then used the resulting dict as the POST data for the test client. Then, I set the content type to "application/json" - this causes raw_post_data to appear, but it is not the same raw_post_data as the mock request.
When you change the content type in the test client, the data parameter is not parsed as a dictionary anymore but sent directly. Try copyin your JSON string directly as the data parameter to your post request, you should receive it in raw_post_data in your application.
Just need to follow the steps as below:
1. set the data attribute to your string.
2. then set the content_type attribute to application/octet-stream.
payload = {'k1':'v1'}
data = json.dumps(payload)
response = self.client.post(url, data=data, content_type='application/octet-stream', **self.auth_headers)
