Django cms content getting published in draft mode
I have installed djangocms-snippet and using placeholder in my template as shown in image I have included placeholder on template page like {% block content %} {% placeholder "Articles" %} {% endblock content %} Issue: whenever I am updating snippet for e.g. news and changing content and then saving its getting reflected automatically in live version without having clicked "publish page changes".Ideally it should only be reflected to the logged in user and after verifying changes are correct I can publish but as soon as i am changing content and saving its getting reflected on live page.Live refers to staging environment here. -

Python unit test : Why need `mock` in a test?
I can not understand why we need mock in some test cases, especially like below: main.py import requests class Blog: def __init__(self, name): self.name = name def posts(self): response = requests.get("https://jsonplaceholder.typicode.com/posts") return response.json() def __repr__(self): return '<Blog: {}>'.format(self.name) test.py import main from unittest import TestCase from unittest.mock import patch class TestBlog(TestCase): @patch('main.Blog') def test_blog_posts(self, MockBlog): blog = MockBlog() blog.posts.return_value = [ { 'userId': 1, 'id': 1, 'title': 'Test Title, 'body': 'Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy\ lies a small unregarded yellow sun.' } ] response = blog.posts() self.assertIsNotNone(response) self.assertIsInstance(response[0], dict) This code is from this blog. What I'm curious about is that as you can see in test code, test code set blog.posts.return_value as some desirable object(dict). But, I think this kind of mocking is useless because this code just test How well the user set the return_value correctly in the test code, not what the real Blog' object really return. What I mean is, even if I make real posts function return 1 or a in main.py, this test code would pass all the tests because the user set the return_value correctly in the test code! Can … -
How to serve a view at every URL endpoint
The reason for my wanting to serve the same view at every URL endpoint, is because the view sends Notification information to the authenticated user. For example, here is the view which has data that I would like served in every page: class NotificationsView(View): def get(self, request, *args, **kwargs): profile = Profile.objects.get(user__username=self.request.user) notifs = profile.user.notifications.unread() return render(request, 'base.html', {'notifs': notifs}) I'm trying to send the context variables into my template to be used with javascript. The JS file lives apart from the template, so I'm attempting to declare the global JS vars in the base template first, then use them in the JS file. base.html: ... {% include "landing/notifications.html" %} <script src="{% static 'js/notify.js' %}" type="text/javascript"></script> {% register_notify_callbacks callbacks='fill_notification_list, fill_notification_badge' %} landing/notifications.html: <script type="text/javascript"> var myuser = '{{request.user}}'; var notifications = '{{notifs}}'; </script> notify.js: ... return '<li><a href="/">' + myuser + notifications + '</a></li>'; }).join('') } } Based on this code, you can see how I've ended up in a predicament where I need to use the CBV to send the proper notifications to the landing/notifications.html in order to make sure the javascript variables can be dynamically rendered for the JS file. I am utterly confused as to how the … -

Django httpresponse returns corrupted file
I'm trying to deploy a Django application i just got handover from an ex-colleague to a server on my network, the application runs perfectly on my laptop with python manage.py runserver I took the application and set up the environment on the server and ran the app there it works fine but there is this part where i return a XLSM file format to the user using HTTPresponse but it returns a corrupted file, the code already saves a copy of the file to be returned in the app folder and this file is fine and not corrupted, also when i compared the two files i found the correct file size is 93 KB but the corrupted returned file is 269 B. The part of the code which returns to the user the file is as follows excel_file = BytesIO() writer = pd.ExcelWriter(excel_file, engine='xlsxwriter') #result_final is the file i save on the hard disk result_final.to_excel(writer, sheet_name='Summary Report') workbook = writer.book my_worksheets = {} for worksheet in workbook.worksheets(): my_worksheets[worksheet.get_name()] = worksheet worksheet = my_worksheets['Summary Report'] workbook.add_vba_project('./vbaProject.bin') worksheet.insert_button('E3', {'macro': 'Macro5', 'caption': 'Load Charts', 'width': 70, 'height': 70}) writer.save() workbook.close() excel_file.seek(0) response = HttpResponse(excel_file.read(), content_type='application/vnd.ms-excel.sheet.macroEnabled.12') response['Content-Disposition'] = 'attachment; filename=Summary Report.xlsm' return response This … -

In Django test there is empty queryset when assigned to variable but not empty when printed in console during debug
I'm debugging Django (1.11.8) test and observing strange behavior: when stopped in debugger and switched to Ipython console typing: Model.objects.all() returns non-empty Queryset. However, when the same expressions is assigned to variable e.g.: obj_qs = Model.objects.all() then obj_qs is empty Queryset. I would expect the same result from both statements. Am I missing something important in tests setup? I'm using both setUpTest() and setUp() methods to initialize objects for the test. -

Writing multiple page pdf from html template using weasy print and django

How to allow page refresh/redirect after Ajax POST submission (of Django form)
I'm a client-side newbie learning the ropes, and need to clarify Ajax concepts. e.preventDefault(); is a typical method of preventing form submission (page refresh) in JS. One use case where the above is handy is Ajax-based form submission. Sample code is: function overwrite_default_submit(e) { // block the default behavior e.preventDefault(); // create and populate the form with data var form_data = new FormData(); form_data.append("reply", text_field.value); // send the form via AJAX var xhr = new XMLHttpRequest(); xhr.open('POST', e.target.action); xhr.setRequestHeader("X-CSRFToken", get_cookie('csrftoken')); xhr.send(form_data); } I have two questions: 1) Imagine the POST request is being sent to a function that ends with a redirect to a different URL. For example, I use Django to develop web applications; a typical Django view may end up with return redirect("home") where home is the home page of the said app. In such a scenario, how does preventDefault() prevent the redirect statement in server-side code from executing? I'm trying to understand the exact mechanics behind it. 2) What if one wanted page refresh (or redirect) to proceed normally after an Ajax POST request? What tweaks need to be made? Would love to see an illustrative example to clarify my concepts. I'm well-versed in Django (Python) so … -

Context variables not resolving under template inheritance using global javascript vars
I'm trying to send context variables into my template to be used with javascript. The JS file lives apart from the template, so I'm attempting to declare the global JS vars in the base template first, then use them in the JS file.

django RequestFactory loses url kwargs
I am trying to switch from using Django Test Client to RequestFactory to speed up my tests. However, requests generated by RequestFactory do not supply proper kwargs to views. Example: this is my view class SomeView(View): def get(self, request, *args, **kwargs): return JsonResponse({'your kwargs': str(kwargs)}) with urlconf url(r'^some_view/(?P<some_kwarg>[\-0-9a-fA-F]+)/$', views.SomeView.as_view(), name='some_view'), and two tests: def test_different_kwargs(): c = Client() response = c.get( reverse('bots:some_view', kwargs={'some_kwarg': '12345'}), ) print('\n\nResponse for TestClient: ', response.content.decode()) rf = RequestFactory() request = rf.get( reverse('bots:some_view', kwargs={'some_kwarg': '12345'}), ) response = SomeView.as_view()(request) print('\n\nResponse for RequestFactory: ', response.content.decode()) What they produce is: Response for TestClient: {"your kwargs": "{'some_kwarg': '12345'}"} Response for RequestFactory: {"your kwargs": "{}"} So, what's the point of RequestFactory if it loses url kwargs? Or is there a way to put them into the view somehow? -
Is there a way that a Django template include is not silent if it fails for developement
I would like to have the possibility that include templates are not silent when they fail Let me explain.. We have a main template A. We have a template to include B that contains an error. When we include template B, this one will not be displayed because it contains an error even if the template_debug = True, and it looks fine. The fact that fails are silent is convenient for a production environment. However, often on the environment of development this can pose problem insofar we do not see that there is a problem since it does not appear. Even if we can often see the error in the console. Also for the debug it is relatively painful as sometimes we do not know where the error comes from. So my question is: would there be a solution (ex: custom template tag include_noisy, or middleware) for the template include not silentious on local machines, and thus correctly display errors as in a normal template? For sure, the silent is still always present when the template_debug = False Thanks in advance -
Django - displaying images on the page using pyuploadcare
Python, Django, pyuploadcare, html5, jquery, The Django documentations for pyuploadcare are useful for image customization and file uploading and stuff like that, but what they don't tell you is how to display the image in the webpage.

wagtail 2.0b1 admin static files issue
