Mock Prestodb connection in Django unittest
I have following setup in my project: Django as API server, Postgres as database, Prestodb for my datastore queries. Postgres is storing django related stuff only while data is stored and fetched through prestodb using raw queries. My challenge is that I want to mock connection of prestodb and all its methods in unit-tests and assert my APIs. Currently I am able to mock main query method of presto client that returns mocked data but when connection is not available tests are failed. Mock for query method decorator looks like this @mock.patch.object(PrestoClient, 'get_select_query_data', mocked_presto_response) If I mock connection class then all other methods like cursor and execute doesn't work. What should be the parameters for mocked connection or is there a better way to mock databases? -

Django Template Loop Not Showing & Form Problems
I am having some issues with my template for loop and a few other things. https://dpaste.org/PJGi 1) The loop is not showing up ever since I made changes to views.py. I want to make sure that the views.py is correct. I think it might have to do with the def get() statement? 2) This keeps getting passed into my URL when I click submit: ?csrfmiddlewaretoken=TOKEN. Is that normal? Regular HTML without forms.py never did this. 3) Recaptcha is not printing the result statements to the console when I click submit. Is that normal for GET requests? I want to make sure the recaptcha is working. object_list is the default context object that has been passed in from the class based view CourseListView. The object_list is a list of all the course models in model = Course -
