Gunicorn Service Environment File Format?
I'm deploying a Django project on an ubuntu machine using gunicorn and nginx, following this tutorial to do it. I have a gunicorn service that looks like this, similar to the one in the tutorial: [Unit] Description=gunicorn daemon After=network.target [Service] User=ubuntu Group=www-data WorkingDirectory=/home/ubuntu/project/mysite EnvironmentFile=/home/ubuntu/.virtualenvs/projectenv/bin/postactivate ExecStart=/home/ubuntu/.virtualenvs/projectenv/bin/gunicorn --access-logfile - --workers 10 --bind unix:/home/ubuntu/project/mysite.sock mysite.wsgi:application [Install] WantedBy=multi-user.target Since, as I understand, the gunicorn service is run in a completely new environment instead of my project's virtual environment I need to find another way to pass it environment variables. I found this page which says I can add an EnvironmentFile to my service file, which I did above. I directed the environment file to my virtualenv's postactivate script, which looks something like this: #!/bin/bash # This hook is sourced after this virtualenv is activated. export DJANGO_DEBUG=False ... Which doesn't work, unsurprisingly. What is the correct format for this EnvironmentFile to be in? -
How do I integrate Django class-based views, modelforms, and bootstrap datetimepicker?
After following this Django docs tutorial, my form isn't working. There are two problems. When I submit the form it doesn't update my object, even if I exclude the optional fields (tags, due_date) and just change the text field of the item. When I try to update the date it complains that it is not a valid datetime. It was working fine before I implemented a ModelForm. Is it not recommended using ModelForm when using JavaScript libraries like bootstrap datetimepicker that expect different date formats than those of the Django model? Am I just overlooking a workaround? Error message when I use the DateTimeField in the form: Enter a valid date/time. Error message when I use the CharField in the form: '10/09/2017 5:41 PM' value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ] format. models.py class Tag(models.Model): created = models.DateTimeField(default=timezone.now, blank=True) name = models.TextField(null=True, blank=True) def __str__(self): return self.name def friendly_created_date(self): created = self.created return created.strftime('%B %d, %Y, %I:%M %p') class Item(models.Model): text = models.TextField(default='') tags = models.ManyToManyField(Tag, blank=True, null=True) due_date = models.DateTimeField(blank=True, null=True) forms.py from django import forms from todos.models import Item, Tag class ItemForm(forms.ModelForm): class Meta: model = Item fields = ['text', 'tags', 'due_date'] text = … -
Django query filter using large array of ids in postgre db
I have bumped into a pretty weird problem passing a query in django to my postgresql database. When I filter my query using large array of ids, the query is very slow and goes up to 70s... After looking for an answer I saw this post which gives a solution to my problem, simply change the ARRAY [ids] in IN statement by VALUES (id1), (id2), ... I tested the solution with a raw query in pgadmin, the query goes from 70s to 300ms... So my question is: How can I do the same command (i.e. not using an array of ids but a query with VALUES) in Django ? Thanks you :) -
Connecting a Numpy calculation with a Django API
I have 3 matrices stored in cache that are used in a calculation process. Overall, they have 50.000 lines and 500 columns. Every time that I need to perform that calculation, I duplicate those 3 matrices, manipulate them, perform the calculation and delete them from the cache. The calculation is triggered by a web service call and the result of the calculation feeds the web service output. The web service is managed by a Django application, while the matrices and the calculation are managed by a Numpy-based application. My problem is related to performance. Every time that Django gets a web service call, it triggers the Numpy-based application that access the cache to duplicate the matrices. The problem is that accessing the cache and duplicating the matrices is taking 5 seconds. In my view, duplicating the matrices should be virtually instantaneous, so I assume the problem is related to accessing the cache. I used the cache solution because it’s the only way that I found to keep the matrices permanent and not related to user sessions. Generally speaking, I have two options to solve the problem: 1) improving the current solution to make the cache access and matrices duplication an … -
Django ModelForm 'instance' param not working as expected
I am using Django's forms to validate API PATCH requests. In the "view" (which I use in quotes because it isn't really a view directly, it is a restless Resource, but that should be irrelevant here) which handles this patch request, self.data contains a dictionary of changes to some of the fields of the License object. I want to instantiate a ModelForm with the instance of the object to be changed. Clearly, though, I am misunderstanding how this works. See below: def handle_patch(self, pk): license = License.objects.get(id=pk) form = LicenseResourceForm(self.data, instance=license) if not form.is_valid(): print(form.errors) If I pass a few fields as data to the above function, form.errors complains about every other required field of the License model, meaning I'm clearly not understanding how setting an instance on a ModelForm works. I added a few debug prints to Django's ModelForm code itself in the clean() method, and as it begins to do the cleaning process, I can see that self.instance is populated with the instance of License that I expect, which confuses me - the ModelForm object knows the instance, but isn't using it to "fill in the blanks" so to speak. So what am I misunderstanding? I must be … -

class based templateview context is not rendering
I have a template view that is supposed to take in a user submitted search. I planning to use the get method to do a query in the get_context_data so that I can show some results on the HTML.

show distance in km or m of each restaurant
I have implemented the feature of showing nearby restaurant from the given coordinates using postgis and geodjango. But I need to find the distance in km or m based on the distance it is nearby from user or given coordinates. I know question related to distance is asked in SO but this one is a bit different. I am showing the list of restaurant(list view) not a detail of restaurant that I will have specific restaurant location from the id. So i need an idea how should I now show the distance for each restaurant in the restaurant list view. My idea is should I pass the lat and lng(that I am passing from the url) as context and use template filter for calculating the distance by doing from django.contrib.gis.geos import GEOSGeometry pnt = GEOSGeometry('SRID=4326;POINT(40.396764 -3.68042)') pnt2 = GEOSGeometry('SRID=4326;POINT( 48.835797 2.329102 )') pnt.distance(pnt2)*100 Here is the code in detail def nearby_restaurant_finder(request, current_lat, current_long): from django.contrib.gis.geos import Point from django.contrib.gis.measure import D user_location = Point(float(current_long), float(current_lat)) distance_from_point = {'km': 500} restaurants = Restaurant.gis.filter( location__distance_lte=(user_location, D(**distance_from_point))) restaurants = restaurants.distance(user_location).order_by('distance') context = { 'restaurants': restaurants } return render(request, 'restaurant/nearby_restaurant.html', context) url(r'^nearby_restaurant/(?P<current_lat>-?\d*.\d*)/(?P<current_long>-?\d*.\d*)/$', views.nearby_restaurant_finder, name="nearby-restaurant"), {% block page %} {% for restaurant in restaurants %} … -
Testing Form In Django With A User Object
I am working on testing - and I have a little form with a good chunk of logic in the clean method. My test looks like this: class DependentFormTest(TestCase): def test_dependent_form_birthdate_out_of_range(self): form_data = { 'first_name': 'Bill', 'last_name': 'Robusin', 'birth_date': '10/12/1801', 'gender': 'Male', 'relationship': 'dependent', 'street_address_1': '123 Any lane', 'city': 'Billson', 'state': 'WA', 'zip': '50133', } form = DependentForm(data=form_data) self.assertFalse(form.is_valid()) In my clean method there is a bit where I access some information about the current user. The snippet that fails looks like this: user_benefit = Benefit.objects.get(user=self.user) This line is what causes my test to error with the following error: Benefit matching query does not exist This is true, because in the test 'user' is 'None'. How do I set a user in my test so that I can test this forms validity? -
Testing with Django: stuck at test database creation
I was having some trouble running tests for my app and I managed to solved them in this previous post. Now executing python manage.py test does go through without raising any errors, but it gets stuck at database creation: When the test database doesn't exist it does create as I can see in pgAdmin, but it gets stuck in the process with this message: enter code hereCreating test database for alias 'default'... It is stuck here forever, so when I finish the process manually and run test again, it says the database exists and prompts me to either delete it and create anew, or cancel the process. I type 'yes' and the process is stuck again with this other message: Destroying old test database 'default'... With pgAdmin open I can't immediately see any new test_dbname database, but if I close and open it again I can, there test_dbname is, but the test task is just stuck there and doesn't go through... A workaround to this problem is this solution, disabling migrations. This way it no longer gets stuck at those messages and the default test is run. . ---------------------------------------------------------------------- Ran 1 test in 0.002s OK However, this just seems to … -
ImportError for Stripe when running Django development server

Changes to django's urls.py not reflected online
I'm running a Django application using NGINX and UWSGI. My URLpatterns used to be this: urlpatterns = [ url(r'^$', views.index), url(r'^binaryQuestionApp/',include('binaryQuestionApp.urls')), url(r'^pointlocations/',include('pointlocations.urls')), url(r'^attributesFromPointsApp/',include('attributesFromPointsApp.urls')), url(r'^admin/', admin.site.urls), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Yet, I wish to change it to this: urlpatterns = [ url(r'^$', views.index), url(r'^collections/',views.collections), ## new line ## url(r'^binaryQuestionApp/',include('binaryQuestionApp.urls')), url(r'^pointlocations/',include('pointlocations.urls')), url(r'^attributesFromPointsApp/',include('attributesFromPointsApp.urls')), url(r'^admin/', admin.site.urls), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Yet, after pushing this to my server (and the .py file does change on the server) I consistently get Django's 404 page: Using the URLconf defined in data_collection_project.urls, Django tried these URL patterns, in this order: ^$ ^binaryQuestionApp/ ^pointlocations/ ^attributesFromPointsApp/ ^admin/ ^media\/(?P<path>.*)$ The current URL, randomurltoget404page, didn't match any of these. If I change something else, for the sake of testing, I can get the change to work.

Django: Load form with dynamic fields
I created a form with multiple dynamic fields (no class attributes) which are added to self.fields in the __init__ function like this: class CustomForm(django.forms.Form): def __init__(dynamic_fields, *args, **kwargs): super(CustomForm, self).__init__(*args, **kwargs) for name, field in dynamic_fields.items(): self.fields[name] = field dynamic_fields = {'val1': IntegerField(), 'val2': FloatField()} CustomForm(dynamic_fields) Now, I don't know how to load the Form after a POST request. Normally, I would do something like: custom_form = CustomForm(request.POST) if custom_form.is_valid(): data = custom_form.cleaned_data ... But as the fields are not known to Form when super is called, I don't know how to load fields manually afterwards. Ideas? -
