The provided Python function get_request_data(request) appears to be a Django view function for handling HTTP GET requests and extracting the data from the request's query parameters. It parses the query parameters and constructs a dictionary containing the data from the request.
Let's break down the function step-by-step:
-
The function takes a
requestobject as input. In Django, arequestobject represents an HTTP request from the client. -
The function initializes an empty dictionary called
context, which will be used to store the parsed data from the request. -
It iterates through the items in the
request.GETdictionary. Therequest.GETdictionary contains the query parameters from the URL of the HTTP GET request. Each item in the dictionary corresponds to a parameter key and its associated value(s). -
For each key in the
request.GETdictionary, it retrieves the associated values using therequest.GET.getlist(key)method. This method returns a list of all values associated with the given key. -
If the length of the
valueslist is greater than 1, it means that the parameter has multiple values (e.g., when the same parameter appears multiple times in the URL). In this case, it stores all the values as a list under the corresponding key in thecontextdictionary. -
If the length of the
valueslist is exactly 1, it means that the parameter has only one value. In this case, it stores that single value under the corresponding key in thecontextdictionary. -
Once all the query parameters have been processed, the function returns the
contextdictionary containing the extracted data from the request.
def get_request_data(request):
context = {}
for key in request.GET.items():
values = request.GET.getlist(key)
if len(values) > 1:
context[key] = [item for item in values]
else:
context[key] = values[0]
return context
