Django / Memcached error: The request's session was deleted before the request completed.
Here is the full error: The request's session was deleted before the request completed. The user may have logged out in a concurrent request, for example. I am using python-memcached with my sessions using my cache. Every few days I get one of these errors. Its thrown by an UpdateError on request.session.save(). It comes from line 60 in sessions/middleware.py. 99% of the time everything works normally. Users report that they are not clicking the logout button. They are also reporting that this happens 5 minutes after logging in, so their sessions are not expiring. I have 0 evictions on my cache for over a month it has been running. If I Google this error, it looks like no one has ever gotten it before. I think the connections to memcached might be closing for some reason. Its running on localhost. The only other time I saw this error is when I set my cache config to a server that had memcached running but it was not listening on that interface. That would generate this exact exception on every request. So is there some way that memcache is refusing to listen for a second or two or dropping connections? Here are … -
Effectively use Multi-table inheritance (one-to-one relationships)
I need several models that inherit from a base class in a one-to-one relationship. In keeping with the Django example: from django.db import models class Place(models.Model): name = models.CharField(max_length=50) class Restaurant(Place): serves_hot_dogs = models.BooleanField(default=False) serves_pizza = models.BooleanField(default=False) class Garage(Place): car_brands_serviced = Models.ManyToManyField(Brands) class Boutique(Place): for = Models.ChoiceField(choices=( ("men", "m"), ("women", "w"), ("kids","k")) # etc Now how do I effectively distinguish between the various types of Places when I iterated them in a template (or view function)? Right now, I only see this solution (if I want to iterate over Places, rather than child models individually): for place in Place.objects.all() try: r = place.restaurant # Do restaurant stuff here except ObjectDoesNotExist: try: g = place.garage # Do garage stuff here except ObjectDoesNotExist: try: b = place.boutique # Do boutique stuff here except ObjectDoesNotExist: # Place is not specified Not even sure how that would translate to a template, but this code seems very wrong and inefficient. As an escape, I guess you could make a choicefield in Place to track which child model is related, but that equates to dangerous denormalisation. Am I somehow overthinking this? How do you do this? -
Using ajax to load a Django template containing Angularjs directives
I'm attempting to use Angularjs's $http method to fetch given Django templates depending on the users selection, each of which includes Angular directives (ng-if) to further filter the content. But while the templates are being inserted just fine, and I can see the directives when I check the html, the filtering isn't actually taking place. When I have the templates insert console logs they cannot find $scope variables that are accessible just above and below where the template is inserted. A template I'm inserting looks like this: <div class="data_point_popup"> {% if id in values_dict %} {% if values_dict|get_item:id|get_item:"not_applicable" == True %} n/a # ... {% else %} {% if id in definitions_dict %} {% if definitions_dict|get_item:id|get_item:"data_type" == "Integer" %} {{ values_dict|get_item:id|get_item:"value"|floatformat:0 }} {% elif definitions_dict|get_item:id|get_item:"data_type" == "Currency" %} <div class="currency eur" ng-if="Page.getCurrencySelection() === 'eur'">€{{ values_dict|get_item:id|get_item:"value_json"|get_item:"eur_value"|floatformat:2 }}</div> <div class="currency gbp" ng-if="Page.getCurrencySelection() === 'gbp'">£{{ values_dict|get_item:id|get_item:"value_json"|get_item:"gbp_value"|floatformat:2 }}</div> <div class="currency usd" ng-if="Page.getCurrencySelection() === 'usd'">${{ values_dict|get_item:id|get_item:"value_json"|get_item:"usd_value"|floatformat:2 }}</div> <div class="currency base" ng-if="Page.getCurrencySelection() === 'base'">Base:{{ values_dict|get_item:id|get_item:"value_json"|get_item:"base_value"|floatformat:2 }}</div> <script>console.log(Page.getCurrencySelection())</script> # ... {% else %} <span style="color: red;">ERROR-NO_DEFINITION</span> <script>console.warn("Unable to find definition for data point {{ id }}.");</script> {% endif %} {% endif %} {% else %} - {% endif %} </div> And my controller looks like: function CompaniesDetailTabController($scope, … -

How can I instantiate a class that is associated with multiple tables and save it in multiple tables?
I am trying to model business processes. I have defined a class to keep the process blue prints (and two classes to keep activities and flows) and then I need to define the same number of tables to keep all of the data associated with the instances of that class. I have a class called ProcessBluePrint. This class is practically defined by two classes called ActivityBluePrint and FlowBluePrint. So far everything works fine. I need to define similar classes to hold data of the instances when created, namely Processes, Activities and Flows. I tried to define the Process class to keep all of the instances of ProcessBluePrint, but I cannot get it right. In the django admin, when i try to add a new process (create an instance of ProcessBluePrint and save it in appropriate tables) Name and Description for the ProcessBluePrint is shown as a text while it should be a drop down. Perhaps the best way to do this is to make this a two step instantiating: step 1=select the ProcessBluePrint option and Step2=Select all the fields associated with that process model. I have attached snapshots to help you get what my problem is. I would really appreciate … -
Django CMS Plugin: How to store combo setting and retrieve on setting window load?
First of all pardon my ignorance as I am kind of new into it. I have been able to show a Dropdown list in Settings Window that fetches data from Db. Now I want to select some value, save and on re-opening of setting modal window I wanna show selected field. So far I figured out that CMS Plugin model actually appears on setting modal window. Below are details models.py class Survey(models.Model): name = models.CharField(max_length=400) description = models.TextField() def __unicode__(self): return (self.name) def questions(self): if self.pk: return Question.objects.filter(survey=self.pk) else: return None class SurveyPluginModel(CMSPlugin): name = models.CharField("Survey Name", max_length=255, default='Survey Name', help_text='Enter Survey Name') description = models.CharField("Survey Description", max_length=500, blank=True, help_text='Write Description here') def __str__(self): return "Returning some Survey Text" forms.py from django import forms from src.survey.models import Survey from src.survey.models import SurveyPluginModel class SurveyForm(forms.ModelForm): all_surveys = Survey.objects.only('name') surveys = forms.ModelChoiceField(queryset=all_surveys) class Meta: model = SurveyPluginModel fields = '__all__' Now if I add a model field in SurveyPluginModel it instantly appears on screen.

Django Rest Framework + Postman
Got a new project, and at the moment I'm kinda lost with this. It seems I can't do any POST by Postman, kinda weird. Doing a GET is ok: url: {{base_url}}/api/sign/user/ headers: Cookie: csrftoken=izFfd3Sn5....; sessionid=dp90f6x0... But when I try to do some POST, I always get this error: http://127.0.0.1:8000/api/sign/account { "detail": "CSRF Failed: CSRF token missing or incorrect." } I used exactly same Headers on this call. csrftoken and sessionid I took it from cookie in the WebApp, as I can't do a login by postman Can some one provide some help?

Django SearchVector matching phone numbers
I have a model that stores phone numbers in a format such as (xxx) xxx-xxxx, and I am currently using SearchVector to search first name, last name, email, and phone number, so that any of the above can be used to find a customer in an autofill form field. The problem I have is that no matter what I do, I don't seem to be able to get phone numbers to match quite smoothly. What I would like to do is have it return anything that matches any number of digits in the phone number, as it is typed. If I use queryset = Customer.objects.annotate(search=SearchVector('phone', 'last_name', 'first_name', 'email')).filter(search=self.q) It will match if I put in xxx or (xxx), and will match if I put in (xxx) xxx or (xxx) xxx- or even xxx xxx-, and it will match the full number, as long as there is a hyphen in the second section. It will not match xxx x or xxx xxx-xx etc. I assumed that this was a problem with it not being formatted correctly, so, just for testing, I tried this: if any(x.isdigit() for x in self.q): q = re.sub("[^0-9]", "", self.q) if len(q) > 6: q = '(' … -
Poll application with indefinite options, prevent voting from off the options displayed

Django aggregation optimization - multiple aggregations on a single reverse foreign key query without requerying the database
I am attempting to use aggregations instead of for loops to calculate year end amounts. To reduce code, I created a method on the model to fetch my queryset, then created multiple @cached_properties to run different calculations with that queryset. All of these calculations are called in the same view, and I am using select_related() to grab the models containing hours before calculating. Unfortunately, when I use aggregations, even with select_related(), I get hits on the database for every @cached_property that has aggregate(Sum()). When I use for loops and values() to get the hours hours, it still hits once for every employee (causing 50+ database hit, but thats better than 600 o_O) Looking for a better way to write this code to further reduce the amount of queries,make the code cleaner, and ideally use aggregation to let the database do the work? Maybe I am not fully understanding how Django handles queries or theres a tool I am unaware and could use some pointers Employee and Activity Models: class Employee(Model): name = CharField() class Activity(Model): a, b = range(2) choices = ( (a, 'a'), (b, 'b') ) employee = ForeignKey(Employee) type = IntegerField(choices=choices) hours = DecimalField() added = DateField() Aggregation … -

How to exclude delete field from inlineformset but still allow delete
I have an inlineformset that I render in my template so the rows are horizontal. Annoyingly, when I loop through the fields to generate the html, this automatically also renders a delete checkbox. I've seen that this is part of visible_fields https://code.djangoproject.com/ticket/20929#comment:4 How can I get rid of this? I want to be able to hide it for now and then use javascript to show the checkboxes with a button. This way I can enter a 'delete mode'. So I still want the user to be able to delete things, I just want the field to stop rendering in my table on page load. <--form is here, management form etc --> {% for form in existing_formset.forms %} <--field headings generated here--> <tr class="{% cycle row1,row2 %}"> <-- visible fields: apparently includes delete checkbox--> {% for field in form.visible_fields %} <--generate horizontal rows with fields--> <td> {{ field.errors.as_ul }} {{ field }} </td> {% endfor %} </tr> {% endfor %} <--more stuff--> -
Can I make a django forms ChoiceField scrollable?
I have a ChoiceField drop down menu in Django form. It has times from 9:00 AM up until 5:30 PM - about 18 items. When someone clicks on the drop down, it shows all the values at once. What I'd like it to do is show only about 3 or 4 values with a scroll bar to the right, so that the user can do the scrolling. The reason I want it this way is because it takes less space and looks better. Anyway to get this going? This is what I have so far: MY_CHOICES = ( ('1', '9:00AM'), ('2', '9:30AM'), ('3', '10:00AM'), ('4', '10:30AM'), ('5', '11:00AM'), ('6', '11:30AM'), ('7', '12:00PM'), ('8', '12:30PM'), ('9', '1:00PM'), ('10', '1:30PM'), ('11', '2:00PM'), ('12', '2:30PM'), ('13', '3:00PM'), ('14', '3:30PM'), ('15', '4:00PM'), ('16', '4:30PM'), ('17', '5:00PM'), ('18', '5:30PM'), ) my_choice_field = forms.ChoiceField(choices=MY_CHOICES) -

Sub-Domain Routing Issue on Production Server Django
I'm using Django-Hosts to handle sub-domain routing in my Django app. Django-hosts is working perfectly fine on my development server. But it's not working fine on the production server. when I visit m.example.com it will redirect me to example.com. I have one project with different apps. I only want the sub-domain to make use of mravmomentapp. E.g project name: mrav apps under: mrav/moneapp mrav/mtwoapp mrav/mravmomentapp My stack is nginx, wsgi, gunicorn. I placed the hosts.py in mrav/hosts.py In my hosts.py if socket.gethostname()=="AM-PC": host_patterns = patterns('', host(r'examplelocal.com:8000', mrav_base_settings.ROOT_URLCONF, name='www'), host(r'm.examplelocal.com:8000', 'mravmomentapp.urls', name='m'), ) ###use this settings in production else: host_patterns = patterns('', host(r'example.com', mrav_base_settings.ROOT_URLCONF, name='www'), host(r'm.example.com', 'mravmomentapp.urls', name='m'), ) In my mravmomentapp.urls I have urlpatterns =[ url(r'^$', mo_views.home_page, name='home_page'), #homepage for subdomain m.example.com ] in my nginx.conf server { listen 80; listen [::]:80; server_name example.com www.example.com *.example.com m.example.com; return 301 https://$server_name$request_uri; } server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name example.com www.example.com; index index.html index.htm index.php; include snippets/ssl-example.com.conf; include snippets/ssl-params.conf; location / { include proxy_params; proxy_pass http://mrav_app_server; } #othersettings } I also created an A host file in my DNS and added my IP ADDRESS to it. What am I missing?
