Profiling Django: what is {posix.write} function?
Profiling Django app to figure out slow functions. I just added some middleware to track function calls, following this blog: http://agiliq.com/blog/2015/07/profiling-django-middlewares/ and I see that the entry of cProfile stats for {posix.write} is one of the longest. Any idea what that is, and where that comes from? Other functions are referenced by their name and package path, so I'm not sure what {posix.write} means. the log looks like this: 204051 function calls (197141 primitive calls) in 0.997 seconds Ordered by: internal time List reduced from 1204 to 50 due to restriction <50> ncalls tottime percall cumtime percall filename:lineno(function) 35 0.305 0.009 0.305 0.009 {posix.write} 95 0.206 0.002 0.207 0.002 {method 'execute' of 'psycopg2.extensions.cursor' objects} 73 0.088 0.001 0.088 0.001 {select.select} 898 0.023 0.000 0.047 0.000 /.venv/lib/python2.7/site-packages/django/db/models/base.py:388(__init__) 1642 0.012 0.000 0.371 0.000 /.venv/lib/python2.7/site-packages/django/template/base.py:806(_resolve_lookup) 1 0.010 0.010 0.011 0.011 {_sass.compile_filename} 1 0.009 0.009 0.009 0.009 {psycopg2._psycopg._connect} 34 0.009 0.000 0.009 0.000 {method 'recv' of '_socket.socket' objects} 39 0.007 0.000 0.007 0.000 {posix.read} 9641/6353 0.006 0.000 0.321 0.000 {getattr} 173 0.006 0.000 0.026 0.000 /.venv/lib/python2.7/site-packages/django/core/urlresolvers.py:425(_reverse_with_prefix) 25769 0.006 0.000 0.007 0.000 {isinstance} Thanks -

Django Urls - two views with same regular expression
I have two views with the same regular expression, as you can see below. It's a Category and an Article view, their entry slugs will never be the same so it should be no problem. But at the moment it doesn't work well, as you prolly know the category-view will get triggered. urls.py urlpatterns = [ url(r'^index', index.Index.as_view(), name='index'), url(r'^search', search.Index.as_view(), name='search'), url(r'^(?P<slug>.+)$', category.Index.as_view(), name='category'), url(r'^(?P<slug>.+)$', article.Index.as_view(), name='article'), ] I tried to reverse from views.category back to urls.py if there is no category to find like this: views.category.py class Index(View): def get(self, request, slug): category = CategoryModel.objects.get(slug=slug) if category is None: return HttpResponseRedirect(reverse('article', args=[slug])) context = { 'category': category } return render(request, 'category/index.html', context) The error (but there is a article with slug 'test123'): NoReverseMatch at /wiki/test123 Reverse for 'article' with arguments '('test123',)' and keyword arguments '{}' not found. 0 pattern(s) tried: [] Using Python 3.6 -
Duplicate indexes appears in the Django-haystack with solr backend
Solr indexes the same model object with duplicate, but id is different. Place/search_indexes.py class PlaceIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) p_key = indexes.IntegerField(model_attr='id',indexed=False) name = indexes.CharField(model_attr='name',null=True) location = indexes.LocationField(model_attr='get_location',indexed=False) avatar = indexes.CharField(null=True,indexed=False) address = indexes.CharField(model_attr='address',null=True,indexed=False) allow_membership = indexes.BooleanField(model_attr='allow_membership') location_x = indexes.DecimalField(model_attr='location_x',indexed=False) location_y = indexes.DecimalField(model_attr='location_y',indexed=False) status = indexes.IntegerField(model_attr='status') city = indexes.CharField(model_attr='city__id') def prepare_avatar(self, obj): if obj.avatar: return obj.avatar.url return None def get_model(self): return Place def index_queryset(self, using=None): return self.get_model().objects.filter(status=Place.Status.ACTIVE, city__status=City.Status.ONLINE).distinct() Solr shows the duplicates with the all equal to each other, except id field. One index's id field is valid the second not present in db. What it might be causing this? Or,at least, is there a way to skip the specific index or object when calling update_index? Not index_queryset() because it doesn't handle indexing per object level? -

python list of dictionaries only updating 1 attribute and skipping others
I have a list of lists containing company objects: companies_list = [companies1, companies2] I have the following function: def get_fund_amount_by_year(companies_list): companies_length = len(companies_list) for idx, companies in enumerate(companies_list): companies1 = companies.values_list('id', flat=True) funding_rounds = FundingRound.objects.filter(company_id__in=companies1).order_by('announced_on') amount_per_year_list = [] for fr in funding_rounds: fr_year = fr.announced_on.year fr_amount = fr.raised_amount_usd if not any(d['year'] == fr_year for d in amount_per_year_list): year_amount = {} year_amount['year'] = fr_year for companies_idx in range(companies_length): year_amount['amount'+str(companies_idx)] = 0 if companies_idx == idx: year_amount['amount'+str(companies_idx)] = fr_amount amount_per_year_list.append(year_amount) else: for year_amount in amount_per_year_list: if year_amount['year'] == fr_year: year_amount['amount'+str(idx)] += fr_amount return amount_per_year_list The problem is the resulting list of dictionaries has only one amount attribute updated.

How to decode a serialized or toArray object from JQuery to Django views?
I am using jQuery sortable() to sort a table in the frontend. I have a button that will send the new order into my backend in Django once the user hit save. When the new order is saved, I am unable to decode the request post. Please see my code below for JQuery: $("#sortable").sortable({ update: function (event, ui) { var order = $(this).sortable('toArray'); $(document).on("click", "button", function () { $.ajax({ data: {csrfmiddlewaretoken: document.getElementsByName('csrfmiddlewaretoken')[0].value, order}, type: 'POST', url: '/sample_route' }); }); } }) I find that I can either use var order = $(this).sortable(‘serialize’); // or var order = $(this).sortable(‘toArray’); To be able to send the data into the backend. Let’s say the order of the ids are the following: <table class="table table-striped table-hover "> <thead> <tr> <th>Priority</th> <th>Report Type</th> <th>Submitted By</th> </tr> </thead> <tbody id="sortable"> {% for idx in reports %} <tr id="id_{{idx.0}}"> <td>{{idx.0}}</td> <td>{{idx.1}}</td> <td>{{idx.2}}</td> </tr> {% endfor %} </tbody> </table><br> If I use serialize; I get this in my Http request body print request.POST['order'] >> id[]=7&id[]=1&id[]=5 If I use toArray; I get this the following Http request: print request.POST >> u'order[]': [u'id_5', u'id_1', u'id_7’] print request.POST['order[]'] >> id_7 ## only prints the last element How can I use either … -

How to replace re "." in Django template url tag
I have Django url routes that looks like this: app_name = 'courses' urlpatterns = [ url(r'./(?P<courseid>[0-9]+)/$', views.viewcourse, name='view_course'), url(r'./(?P<courseid>[0-9]+)/review/$', views.reviewcourse, name='review_course') ] The "." in the regular expression will usually be replaced by a slug, e.g.: courses/computer-science/3/ Now I need a link in my 'view course' template to take the user to the review page, i.e: courses/computer-science/3/review/ I could do this by simply appending review to the current url: {{ request.path }}review However, I would rather do it the 'correct' way using a template url tag {% url 'courses:review_course' courseid=course.pk %} However, this produces: courses/30/review, which of course fails. Is it possible to generate the correct link using the {% url %} tag without having to change the "." into a name capture parameter? -
Django deployment on Heroku, upgrading to Cedar-14, Import Settings Error
ImportError: Could not import settings 'settings.prod' (Is it on sys.path? Is there an import error in the settings file?) I built this app back in 2013-2014, and it hasn't seen much maintenance since then. But there's a problem now, some AWS keys need to be changed, but I can't deploy the app. git push heroku master results in a failed build unless I do heroku config:set DISABLE_COLLECTSTATIC=0 So, I did that, knowing it would probably break the site, but it never even gets to that point, because then I find out I can't deploy until I upgrade to Cedar-14.

Number of customers per week
In my django project, it is possible to show every customer in the application with CustomerProfile.objects.all() and find the creation date of a specific customer with In [12]: cust = CustomerProfile.objects.get(pk=100) In [13]: cust.user.date_joined Out[13]: datetime.datetime(2017, 7, 28, 14, 43, 51, 925548) In [14]: cust Out[14]: <CustomerProfile: Chantal Goyette's customer profile> According to the creation date, I would like to make a listing of how many customers has been created for each week. An example of the result could be ... week 28 : [ 09/07/2017 - 15/07/2017 ] - Count : 201 customers ... I probably need a range start_date and end_date where we will list that kind of information. start_date will be the date of the first customer created and the first week create would be the week of this first date. Obviously, the end_date is today and the last week est the week of this end_date. Sorry, I am a very new programmer in python/django. Could anyone have an idea how I could implement such information?
