How do you access models from other installed apps in Django when in the same subdirectory?
I have the following structure for my project: myproject/ |-- myproject/ | |-- __init__.py | |-- settings.py | |-- urls.py | |-- wsgi.py |-- apps/ | |-- dashboard/ | | |-- static/ | | |-- templates/ | | |-- __init__.py | | |-- admin.py | | |-- apps.py | | |-- forms.py | | |-- models.py | | |-- tests.py | | |-- views.py | |-- data/ | | |-- __init__.py | | |-- apps.py | | |-- models.py | | |-- router.py | | |-- tests.py | |-- __init__.py |-- manage.py The settings file has these installed apps added: 'apps.data', 'apps.dashboard', In the main project I can import from the apps I've created no issues. However, the dashboard app is dependant on the data app and I can't seem to import from the data app. urls.py imports 'import apps.dashboard.views' with no issues but I've tried a number of things to import the models from data into dashboard. I'm using the models from data in the dashboard views. None of the following work: from data.models import ModelName from apps.data.models import ModelName from .data.models import ModelName from .apps.data.models import ModelName I get 'ImportError: No module named data.models' regardless.

Display Word Count in Blog Post with Wagtail
I am wondering how to create a template tag that will get the word count for an entire blog post in Wagtail. I have looked around and seen some different ways to do with with python, but not quite sure how to do it with wagtail given views are often abstracted away. It seems like the query also gets more complex given that in many cases there can be multiple parts to a wagtail template (intro, body, etc.) that the creator might want to count. I noticed there is also a nice package that does this in the admin for you, but I would like to display it on the user side. I am guessing this is a pretty simple answer, but am still not familiar with passing new variables to templates in Wagtail without a view. Thanks! -
Django customize dumpdata output json to meet with elasticsearch default document format
Is there a way to replace field with with a custom name while dumping django model data? I am trying to update documents in elasticsearch. Elasticsearch expects pk field labelled as id and it do not expect a nested field named as field itself. Default dumpdata for a single object is as given below [ { "fields": { "field1": 1, "field2": null, ... }, "model": "core.mymodel", "pk": 1 } ] What required is [ { "_index": "myIndex", "_type":"core.mymodel" "_id": 1, "_source": { "field_1": "value_1", "field_2": "value_2", ... "field_n": "value_n" } } ] Is there a way to customize the output of django's dumpdata? Any help is greatly appreciated. TIA -
404 error when adding a new app on django
Hi there! I'm having an issue with my site, in making and incorporating a second app. The first works perfectly. You can see the demo site here: http://216.158.236.51 but when I try to visit the new url pages created [ http://216.158.236.51/signup ] for example, it just gives me a 404. It gives me a 404 for both the new app pages and for other new pages created within the first app. I'm pretty sure I did everything correctly from the django side. Not sure if I have to reload the nginx or gunicorn. or what backend problems there are... any advice would be great. my url patterns look like this: from django.conf.urls import url, include from django.contrib import admin from blackcrowtours import views from accounts import views from django.conf.urls.static import static from django.conf import settings urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^accounts/', include('accounts.urls'), name='accounts'), url(r'^signup/', accounts.views.signup, name='signup'), url(r'^$', views.home, name='home'), url(r'^yourtrips/', views.yourtrips, name='yourtrips'), url(r'^about/', views.about, name='about'), url(r'^whyus/', views.whyus, name='whyus'), url(r'^accommodations/', views.accommodations, name='accommodations'), url(r'^yourguides/', views.yourguides, name='yourguides'), url(r'^westerneurotrip/', views.westerneurotrip, name='westerneurotrip'), url(r'^contact/', views.contact, name='contact'), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) account app views from django.shortcuts import render from django.contrib.auth.models import User from django.contrib.auth import authenticate, login def signup(request): return render(request, 'accounts/signup.html') account app urls from django.conf.urls … -
How to test a Django on_commit hook without truncating?
The on_commit function has been added to Django 1.9 to be able to trigger an action (e.g. a Celery task) after the current transaction has committed. They mention later in the docs that one should use TransactionTestCase to test features that rely on that function. However, unlike TestCase (which uses transactions and rolls them back), TransactionTestCase empties the whole database after each test. Unfortunately, I have data migrations that preload some useful data inside the database, which means that subsequent tests do not work anymore after the first test clears the database. I ended up resorting to a dirty trick by mocking on_commit : with mock.patch.object(transaction, 'on_commit', lambda t: t()): test_something() Is there a better way? -
How to handle different POST request on class-based-view?
i'm working with Django, and until now i have only had the necesity to make a single POST request for the page to work, but now i need to make multiple POST request, and i don't know how to handle a different POST request with the same method. Maybe i'm not explaining me very well. I have a view.py like class List(View): def post(self, request): #Receive the JSON return JsonResponse(data,safe=False) #data is a list of dicts [] def get(self,request): return render(request,'list.html') list =List.as_view() Now, with this i return information to create a list of elements, and each of them has a button that opens a modal where i want to show more information. The thing is, i could just send all the information needed with the post method i have, but i don't think is correct to send too much information with one request when not all of it could be used. So, my idea is that the button first make a new POST request for tha data i need, and then create the modal with it. My problem is that i don't know how to handle the second request, because, in theory, if i send another request, will be … -
Seedstar's django-react-redux boilerplate - How to access the admin area?

Django - Change URL path for adding user within admin (/admin/auth/user/add/)
I'm currently overriding admin templates for the User and Group models. Per the image below, the overridden templates reside in a sub-directory under a templates directory (see below). My ultimate goal is to override the {% block breadcrumbs %} within the templates. As a result I would like to change the default url address for some of the pages. For example when adding a user to the admin, the default url is "http://127.0.0.1:8000/admin/auth/user/add/." How can I change this to "http://127.0.0.1:8000/admin/portfolio/adduser/." -

Excluding multiple app in django dumpdata using call_command
I'm using call_command to launch a datadump, I would like to exclude multiple apps, so if I was not using call_command, I would do it like the django documentation tell to do it : python manage.py dumpdata --format json -e app1 -e app2 But in call_command I don't know how I should call it : from django.core.management import call_command call_command("dumpdata", format="json", ?) What is not working : call_command("dumpdata", format="json", exclude="app1") call_command("dumpdata", format="json", exclude="app1 app2") # CommandError: No installed app with label 'a'. call_command("dumpdata", format="json", e="app1") call_command("dumpdata", format="json", e="app1 app2") # Does not fail but does not exclude anything either call_command("dumpdata", format="json", e="app1", e="app2") # SyntaxError: keyword argument repeated Is it even possible to exclude something from dumpdata using call_command ?

How to Handle Incomplete Django/Nginx File Server URLs?
I have a Django website that uses Nginx on a separate file server to serve up images uploaded by my users. When any user views another user's photos, the link to the photo will have this structure: https://fs01.mysite.com/media/photos/<username>_<photo-id>.jpg When the page is rendered, the user's photo is served up by the file server (fs). But what is the Nginx way of handling incomplete (one could also say incorrect) requests to subdirectories of the above URL? For example, if a user enters this URL: https://fs01.mysite.com ...they see Nginx's default "Welcome to nginx on ..." page. If they enter this URL: https://fs01.mysite.com/media ...they'll get the Nginx "404 Not Found" page. And if they enter this URL: https://fs01.mysite.com/media/photos ...they'll get the Nginx "403 Forbidden" page. How do you handle these situations in Nginx? -

How To: Grainy landing page image loading before full-res version?
I'm struggling to optimise load times for my landing page. Despite having all image assets saved for Web, with exceptionally low bandwidth internet connection my image on the landing page is still unsatisfactorily slow to load. I've seen that the Barclays homepage (http://www.barclays.co.uk/) has a nice feature where initially a grainy version of the main image is shown, followed by a full-res version being loaded once the other assets on the page have fully loaded. I want to achieve this behaviour for my landing page. Does anyone have any sources/tutorials on how this is implemented? I'm running Django 1.7. Thanks! -
Filtering using viewsets in django rest framework
Please consider these three models: class Movie(models.Model): name = models.CharField(max_length=254, unique=True) language = models.CharField(max_length=14) synopsis = models.TextField() class TimeTable(models.Model): date = models.DateField() class Show(models.Model): day = models.ForeignKey(TimeTable) time = models.TimeField(choices=CHOICE_TIME) movie = models.ForeignKey(Movie) class Meta: unique_together = ('day', 'time') And each of them has their serializers: class MovieSerializer(serializers.HyperlinkedModelSerializer): movie_id = serializers.IntegerField(read_only=True, source="id") class Meta: model = Movie fields = '__all__' def get_censor_rating(self, obj): return obj.get_censor_rating_display() class TimeTableSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = TimeTable fields = '__all__' class ShowSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Show fields = '__all__' And their routers router.register(r'movie-list', views.MovieViewSet) router.register(r'time-table', views.TimeTableViewSet) router.register(r'show-list', views.ShowViewSet) Now I would like to get all the TimeTable objects (i.e. date list) by filtering all the Show objects by a specific movie object.

Django CloudinaryField uploaded image URL is wrong
When uploading an image to Cloudinary using the CloudinaryField in my model, the file URL is being prepended with image/upload which yields an invalid image URL when attempting to view in the template. models.py image = CloudinaryField('image', blank=True, null=True) views.py from cloudinary.uploader import upload if form.is_valid(): instance = form.save(commit=True) image_data = re.sub('^data:image/.+;base64,', '', data['graphic']).decode('base64') image_file = ContentFile(image_data, 'your-image.png') public_id_string = str(instance.id) + settings.CLOUDINARY_SUFFIX response = upload(image_file, tags=DEFAULT_TAG, public_id=public_id_string, folder='') instance.image = response['public_id'] instance.save() return HttpResponse(status=201) Object in Admin Here you can see the incorrect file name with the appended folder 'image/upload'.

Django Upload Image to AWS S3 Not Working After Upgrade to Django 1.10
I have (finally) upgraded to Django 1.10 from Django 1.8 and while there has been some obvious challenges, the only struggle is my image upload to S3. While upgrading Django, I was also forced to upgrade Boto & PIL. While the original image will still correctly upload to requested bucket, the save function that would create a thumb and would save it to another bucket no longer works. Here is my code that was working correctly until the Django/Boto/PIL upgrade: class Photo(models.Model): ... def save(self, *args, **kwargs): super(Photo, self).save(*args, **kwargs) self.create_avatar_thumb() def create_avatar_thumb(self): import os from PIL import Image from django.core.files.storage import default_storage as storage if not self.filename: return "" file_path = self.filename.name filename_base, filename_ext = os.path.splitext(file_path) original_file_path = "%s%s" % (filename_base, filename_ext) xm_file_path = original_file_path.replace('originals/', 'xm/') if storage.exists(xm_file_path): return "exists" # resize the original image to xs f = storage.open(file_path, 'r') image = Image.open(f) print image # example 1 xm_size = 40, 40 image.thumbnail(xm_size, Image.ANTIALIAS) f_thumb = storage.open(xm_file_path, "w") print f_thumb # example 2 image.save(f_thumb, quality=100) f_thumb.close() My testing: I get no errors running this script.

I want to create a serializer wherein I can return the details of both the Profile and User Model. So far I can return the details of the user if I use UserSerializer instead of the ProfileUserCombinedSerializer below.
