Django: QuerySet evaluation
Django 1.11.2 In the example, below I have got a QuerySet "arts". I iterate through it in the view (that list comprehension). The transmit the queryset to the template. Ant in the template I again iterate through it in the for loop. In the documentation I can read that QuerySets are evaluated in case of iteration. This is the documentation: https://docs.djangoproject.com/en/1.11/ref/models/querysets/#when-querysets-are-evaluated But I organized a log file for PostgreSQL. And try to control database hits: tail -f postgresql-2017-07-20_120840.log Well, there is only one hit in this case. Could you comment on this. As far as I can understand the QuerySet was evaluated when that list comprehension worked. Then it remembered it state: it is already evaluated. And in the template it just worked without evaluation. Could you comment on this: am I right. If I'm wrong, then why only one evaluation happened? views.py class AsciiView(View): def get(self, request): arts = Art.objects.all() if arts: points = [(art.lat, art.lon) for art in arts if (art.lat and art.lon)] else: points = [] return render(request, "ascii_chan/ascii_chan.html", {"arts": arts, "points": points}) ascii_chan.html {% for art in arts %} <div class="art"> <h2 class="art-title">{{ art.title }} {{ art.created }}</h2> <pre class="art-body">{{ art.art }}</pre> </div> {% empty %} … -
I'm confused with django project root and the virtualenv. Please guide
I'm new to django and have a virtualenv outside my django project directory. When I download open source django apps like python_social_auth using pip install, the apps reside in the virtualenv's site-packages directory and not in the project root. But I import them in my projects. Should I keep a copy of the downloaded apps in my projects root? Would that be necessary if I wanted to deploy the project? -

Where is the declaration of objects of django model?
In django documentation, it say that we can retrieve data entry as below entry = Entry.objects.get(pk=1) Entry is a model class in models.py. I tried to find the declaration of objects, but I can't find its declaration in manager.py, just know it is a instance of Manager. So, where is the declaration of objects? Does it represent a set of Entry instances? -

Deploying multiple django sites with mod_wsgi apache linux
I wish to deploy multiple Django sites (say 2 for now - www.example.com, www.example2.com) using apache2 mod_wsgi. Here are the steps I followed in a fresh Ubuntu 16.04 installations. I've set alias python=python3 in my .bashrc as I am working in python3 packages installed: apache2 - sudo apt-get install apache2 mod_wsgi - sudo apt-get install libapache2-mod-wsgi-py3 Django(V1.11) - sudo apt-get install python3-django Then I've created two projects inside /var/www/ django-admin startproject example django-admin startproject example2 then I did the followings for both the projects (I've mentioned only one, the other one is exactly the same except replacing example with example2) /var/www/example/example/settings.py ALLOWED_HOSTS = ['example.com', 'www.example.com'] /var/www/example/example/wsgi.py #os.environ.setdefault("DJANGO_SETTINGS_MODULE", "example.settings") os.environ["DJANGO_SETTINGS_MODULE"] = "example.settings" /etc/apache2/sites-available/example.conf <VirtualHost *:80> ServerName www.example.com ServerAlias example.com ServerAdmin admin@example.com DocumentRoot /var/www/example WSGIScriptAlias / /var/www/example/example/wsgi.py ErrorLog /var/www/example/error.log </VirtualHost> Also, I've added /etc/apache2/apache2.conf WSGIPythonPath /var/www/example I've called a2ensite for both example.conf and example2.conf Once I restart apache I could now access www.example.com successfully, but www.example2.com gives an internal server error(500). I thought that's because I've only included one path for WSGIPythonPath in apache2.conf and changed it as /etc/apache2/apache2.conf WSGIPythonPath /var/www/example:/var/www/example2 But however, I now get an internal server error(500) for both. in both cases, the error message is ImportError: No module … -
MySQL query with list of values
I have a table with over then 50kk rows. trackpoint: +----+------------+-------------------+ | id | created_at | tag | +----+------------+-------------------+ | 1 | 1484407910 | visitorDevice643 | | 2 | 1484407913 | visitorDevice643 | | 3 | 1484407916 | visitorDevice643 | | 4 | 1484393575 | anonymousDevice16 | | 5 | 1484393578 | anonymousDevice16 | +----+------------+-------------------+ where 'created_at' is a timestamp of row added. and i have a list of timestamps, for example like this one: timestamps = [1502744400, 1502830800, 1502917200] I need to select all timestamp in every interval between i and i+1 of timestamp. Using Django ORM it's look like: step = 86400 for ts in timestamps[:-1]: trackpoint_set.filter(created_at__gte=ts,created_at__lt=ts + step).values('tag').distinct().count() Because of actually timestamps list is very very longer and table has many of rows, finally i getting 500 time-out So, my question is, how to for it in ONE raw SQL query join rows and list of values, so it looks like [(1502744400, 650), (1502830800, 1550)...] -

How to GET from a model, showing its related models' details in the JSON response?
I am writing a small system of which a Transaction has an Account and Category related to it. Currently I'm using PrimaryKeyRelatedField in the TransactionSerializer. I need to, when GETing all the transactions or just one, to return the related Account and Category details in the JSON response. By using PrimaryKeyRelatedField, the response is alike this: class TransactionSerializer(serializers.ModelSerializer): account = serializers.PrimaryKeyRelatedField(read_only=True) category = serializers.PrimaryKeyRelatedField(read_only=True) # output: [ transaction: { id: 1, account: 1 category: 3, ... }, ... ] To bring the details the related account and category, I've done the following in the TransactionSerializer: class TransactionSerializer(serializers.ModelSerializer): account = AccountSerializer() category = CategorySerializer() # output: [ transaction: { id: 1, account: { id: 1, name: "Foo", ... } category: { id: 3, name: "Bar", ... }, ... }, ... ] But then I cannot create a new Transaction. It shows an error saying account and category are expected to be a dictionary but got str. I've tried moving the fields to read_only within the serializer, but then another error says these fields should be within fields list. So this is my problem. How do I create a new Transaction, assigning an account and category by ID, and yet when retrieving … -
Finding and logging dynamic text that needs to be translated in django
When django begins translating the page, I would like to find the texts that were marked for translation, but django did not find the msgid for the same in the po/mo file If I can find it, I would then log it for further processing Example, message_to_be_translated = _("Hello") this_message_is_marked_but_wont_be_translated = _(some_variable_name_whose_value_we_dont_know_now) I would like to log the value of "some_variable_name_whose_value_we_dont_know_now" during run time to a file or something. The reason we wont know the value before hand is it could be from a third party api it could come from a user request -
How to write urls and views when a OneToOne field is a lookup field?
I have a situation where I'm storing the user profile in a different django model. class Profile(models.Model): user = models.OneToOneField(User, primary_key=True) address = models.CharField(max_length=1000) Using default Model ViewSet I get the following URL to GET/UPDATE a particular instance of the profile /api/profile/user Now, since I'm using token authentication, the client only has a token and is not aware of the user. How can a write a URL of the following form /api/profile This seems more natural to me as a user can have only one Profile object and hence his token should be sufficient to do all the operations in his API calls. Writing custom views is one option but is there any way I can leverage DRF to achieve the same with minimal manual implementation? -
django group by aggregate
I have the following query set in django query_set = JoineryLabour.objects.filter(quote_no = qt.quote_no).values("Hours", "Aspect", "JoineryID") This gives me the following output |Hours|Aspect|JoineryID |100 |Load |123 |50 |Cut |123 |300 |Load |123 |50 |Load |234 What I want is that, hours will be added with the same JoineryID and grouped by Aspect. Like the following: |Hours|Aspect|JoineryID |400 |Load |123 |50 |Cut |123 |50 |Load |234 is it possible to do it in query? The aspect list is dynamic and can be long. I can manage to do it if it's of the fixed size, however, the list is dynamic and I am using nested loops for that. Any advice will be highly appreciated. -

Django heroku deployment Server Error Due to Staticfiles
With DEBUG = True the page loads from Django without css and js as expected. When DEBUG = False a server 500 error is thrown. The heroku sentry addon says this is due to Missing staticfiles manifest entry for 'css/base.css' When base.css is removed, the same error is thrown for the next static file linked via {% static 'filename' %} Once I set the STATICFILES_STORAGE to django.contrib.staticfiles.storage.StaticFilesStorage in settings, I had the same functionality as when DEBUG = True. i.e. templates load (and cdn linked bootstrap) but none of the custom staticfiles in the /static/ of my apps. Why is this the case? I want to be able to serve the static files with AWS but if this isn't functioning properly (throwing Server Errors because of Missing staticfiles manifest errors) then I'm unsure if it will work properly when the files are served from AWS. -

django rest framework order listview by serializer specific field
So I currently have a Drink serializer built using django rest framework. It has a field count_need that i obtain using a SerializerMethodField, which is not part of the Drink model. It also has a timestamp field that is part of the model. How can I order the ListAPI view by either timestamp or count_need based on parameters from a get request like /api/drink/?ordering=timestamp. Currently, i have ordering fields specified in the ListAPI view ordering_fields = ('count_need', 'timestamp', ) but it doesnt seem to be ordering the apiview on either query. I can order it by timestamp through the get_queryset method but this doesnt work for count_need because it is not part of the model. -
Food Ordering Website Process (Django)
apologies if this question is not suitable on stackoverflow. I'm making an food ordering website through Django (one restaurant only). I want to be able to identify who ordered what (through user accounts) So please correct me if I am wrong on the process here: Create an app (for "Menu") Create an app (for UserAuth?) Create a model (for "MenuItems") inside "Menu" app User needs to be able to add MenuItems to their "Basket" (how do I do this?) Admin should be able to remove MenuItems from the "Basket" of specific users after the food has been collected (how do I do this?) Make views for home (sitename/), lists of MenuItems (sitename/menu), "Basket" (sitename/basket - this would have an order button), Make a checkout view (sitename/checkout) after pressing Order button - this should add the "MenuItems" in "Basket" to the basket database..? Are there things I am missing, or things I am doing completely wrong? Thank you in advance for all answers! -
when to map http methods to view methods django rest framework
I have seen viewsets implemented like this: can we expand on this line of code in the django rest frameworks docs: "If we need to, we can bind this viewset into two separate views, like so:" user_list = UserViewSet.as_view({'get': 'list'}) user_detail = UserViewSet.as_view({'get': 'retrieve'}) where would user_list and user_detail be connected to / used? more so when would you map the http methods while using viewsets or generic views? Because I have seen examples like this for view sets not using the mapping and using them. Example of using can we talk about how this works and how it is connected? task_list = TaskViewSet.as_view({ 'get': 'list', 'post': 'create' }) task_detail = TaskViewSet.as_view({ 'get': 'retrieve', 'put': 'update', 'patch': 'partial_update', 'delete': 'destroy' }) task_router = DefaultRouter() task_router.register(r'tasks', TaskViewSet) and also what is up with this: @detail_route(methods=['post']) def set_password(self, request, pk=None): if we have the route decorators why do we have in url mapping? What is the difference between them? -
exception handling while using django and django rest framework
While using django and django rest framework and strictly using the frame work code. Example, using a router connected to a view set to a serializer into a model. What I mean is no custom code, other than what is required to feed into the django rest frameworks code, do we not need exceptions? I ask because in all the code examples I have seen, I have yet to see a try catch block. thank you
