Python (developent environment): Install Python 3.5.2, pip, and virtualenv on Windows
I'm having a problem trying to get the PowerShell virtualenvwrapper installed. Bellow is the process I'm going through: /****** Experienced Python/Django developers often choose to instead run their Python apps within independent Python virtual environments. These allow developers to have multiple different Django environments on a single computer, allowing them to create new websites (using the latest version of Django)while still maintaining websites that rely on older versions. The Django developer team itself recommends that you use Python virtual environments. ******/ 1. Access cmd as admin cd C:\ mkdir Django cd Django 2.

Django project with Google Calendars API
I have been working on a Django application which uses the Google Calendars API to manage meetings (add meetings to a user's calendar, send meeting invitations to people etc). There were some inconsistencies however with calendar events not appearing in some users calendars. I started looking into this, and having not had the Google Calendars API running within my development environment previously (although I had access to the code used for the calendars on the application in the status that it was in prior to when I started working on it), I followed parts of the tutorials at developers.google.com to try and get the existing Calendar API up and running on my development machine, but have somehow managed to break the working code when trying to add the Calendars API to it. When I now try to browse to my website by typing www.mysite.co.uk in the browser, I get an error page which says: NameError at /projects/my-projects/ global name 'h_user' is not defined Request Method: GET Request URL: http://www.mysite.co.uk/projects/my-projects/ Django Version: 1.9.1 Exception Type: NameError Exception Value: global name 'h_user' is not defined Exception Location: /code/moon/core/templatetags/getters.py in get_invite_details, line 153 Python Executable: /usr/bin/python Python Version: 2.7.6 Python Path: ['/code/moon', '/usr/local/bin', … -

Retrieve all reverse foreign keys in Django
Given a specific Placerating object, which points to a ThePlace object, how to retrieve all ThePlace objects which points to this ThePlace object. Please note that ThePlace has a recursive relationship to itself. Model: class ThePlace(models.Model): author = models.ForeignKey('auth.User') upperlevelplace = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, related_name='upperlevelplaces') class Placerating(models.Model): theplace = models.ForeignKey('ThePlace', on_delete=models.CASCADE, null=True, related_name='placeratings') I have tried this View: placerating = Placerating.objects.get(pk=15) qs = placerating.theplace.upperlevelplaces() print(qs) But I get the following error: qs = placerating.theplace.upperlevelplaces() File "C:\aa\aa\env\lib\site-packages\django\db\models\fields\related_descriptors.py", line 505, in __call__manager = getattr(self.model, kwargs.pop('manager')) KeyError: u'manager' -
Ordering dictionary in context Django
I looked at this thread, with an example of sorting dictionaries. I have a dictionary of programme objects where the key is a programme object and the value is a lookup of the number of related Project objects. def DepartmentDetail(request, pk): department = Department.objects.get(pk=pk) programmes = Programme.objects.all().filter(department=department).exclude(active=False).order_by('long_name') matrix = {} for p in programmes: prj = Project.objects.all().filter(programme=p) matrix[p] = str(len(prj)) return render(request, 'sysadmin/department.html',{'department': department, 'programmes': programmes, 'matrix': sorted(matrix.items())}) In the model, Programme returns a string 'long_name', so I believe that I am trying to sort a string key and a string value. In the template I get to the keys and values as so, {% for programme, n in matrix %} This gives me the error.. unorderable types: Programme() < Programme() I don't really understand the error, in the python 3 documentation it states that the sorted() method accepts any iterable - So why does this happen? I'm looking at collections.OrderedDict to solve the problem, but I want to know why this doesn't work. Thanx. -
After celery delay() called, it takes almost 5 to 10 seconds for the tasks to start executing in worker
I'm currently working on an app with following configuration: Django 1.8 Python 2.7 Celery 3.1.x (Amazon SQS as borker url) I'm currently running multiple celery each with concurrency = 4. So my question is when I call celery delay() in my code, it takes almost 5 to 10 seconds for the tasks to start executing in my worker. I want to know why I'm getting this delay and how can I reduce it so that my takes the task immediately as I call delay(). I have checked the same using RabbitMQ and I can see that the tasks starts executing as soon as I call delay(). Thanks In Advance -

Making simultaneous AJAX calls to separate Django views
I have a Django view that runs a particular function when a POST request is received. Snippet: def run_function(request): if request.method == 'POST': run_some_function() This is called via AJAX as follows: $.ajax({ 'type' : 'POST', 'url' : '/run_function/', 'data' : data, 'success' : function(json) { // Display results to user } }); This works as expected. However, this particular function can take a while to run, so I want to display progress information to the user. Luckily, I have another function that can return the progress (an integer between 0-100) of the task. Snippet: def get_progress(request): progress = calculate_progress() return HttpResponse(json.dumps(progress), content_type="application/json") I can then make an AJAX call every X seconds to get the progress and update my progress bar: function check_progress() { $.ajax({ 'type' : 'POST', 'url' : '/get_progress/', 'success' : function(response) { if (response >= 100) { // Update progress bar to 100% and clearInterval } else { // Update the progress bar based on the value returned by get_progress } } }); } var check = setInterval(check_progress, 500); The problem is...how can I do both simultaneously? I need to be able to make the AJAX call to run the function and make the AJAX calls to … -
