Django: Image Compression
I'm trying to compress Image before Uploading it to the database. Here's what I tried, from PIL import Image as Img from PIL import Image try: from StringIO import StringIO except ImportError: from io import StringIO class Profile(models.Model): profile = models.ImageField(upload_to='user_image', blank=True) def save(self, *args, **kwargs): if self.profile: img = Img.open(StringIO.StringIO(self.profile.read())) if img.mode != 'RGB': img = img.convert('RGB') img.thumbnail((self.profile.width / 1.5, self.profile.height / 1.5), Img.ANTIALIAS) output = StringIO.StringIO() img.save(output, format='JPEG', quality=70) output.seek(0) self.profile = InMemoryUploadedFile(output, 'ImageField', "%s.jpg" % self.profile.name.split('.')[0], 'image/jpeg', output.len, None) super(Profile, self).save(*args, **kwargs) Problem is, whenever I try to upload an image it's raising an error, img = Img.open(StringIO.StringIO(self.profile.read())) type object '_io.StringIO' has no attribute 'StringIO' How can we fix that? Thank You very much . . . -

ListView and a form in single page
I have a blog.html which I will list all blog posts in my model using a generic class-based view ListView and it will point to www.example.com/blog. I also want to add a form not by pointing to a new page/url but all the list of blog posts plus that form. This post has a similar situation like me and the answer says add the form to TEMPLATE_CONTEXT_PROCESSORS. So after doing this, how can I use the form in my blog.html? -
Django refering to same model instances in Abstract Model
I have an abstract model from which a couple of my main models are inherited. Main difficulty in this case is that I have a need in reference to the same model, like a ForeignKey to self. I have read that the ForeignKey is not possible in abstract models and GenericForeignKey can help, however I can`t really make it work. As I understand structure should be somethig like following: class BaseModel(models.Model): versions = GenericRelation('self') date_created = models.DateTimeField(default=datetime.datetime.now) is_deleted = models.BooleanField(default=False) content_type = models.ForeignKey(ContentType, blank=True, null=True) object_id = models.PositiveIntegerField(blank=True, null=True) content_object = GenericForeignKey('content_type', 'object_id') class FirstModel(BaseModel): some_fields... class AnotherModel(BaseModel): another_fields... But with this approach I get an error: >>> item1 = FirstModel.objects.get(id=1) >>> item2 = FirstModel.objects.get(id=2) >>> item2.content_object = item1 Traceback (most recent call last): File "<input>", line 1, in <module> File "/home/michael/.virtualenvs/diagspecgen/lib/python3.6/site-packages/django/contrib/contenttypes/fields.py", line 245, in __set__ ct = self.get_content_type(obj=value) File "/home/michael/.virtualenvs/diagspecgen/lib/python3.6/site-packages/django/contrib/contenttypes/fields.py", line 163, in get_content_type return ContentType.objects.db_manager(obj._state.db).get_for_model( AttributeError: 'ReverseGenericRelatedObjectsDescriptor' object has no attribute '_state' Is that I am trying to reach is absolutly impossible and the only solution is to explicitly create needed fields in existing models? Thanks in advanse for your suggestions. -

Django display an image while rendering request
I want a simple loading screen to be displayed while my django function is done. I read that Ajax might be able to do this, but non of the explanations are clear. So basically i have a small index view: def index(request): return render(request, 'index.html', {'form': forms.AnalysisType()}) This index page has a Submit button, and when it is pressed a plot view is rendered. The plot view takes some time to load, an i would like to display a loading GIF in my page while it loads. The plot view is long and complicated, but in the end it should return a render(request) call. I tried adding something like this to my index.html template, but it did not work: <script> $(document).ready(function () { //Attach the ajaxStart and ajaxComplete event to the div $('#prgs').ajaxStart(function() { $(this).show(); }); $('#prgs').ajaxComplete(function() { $(this).hide(); }); //Perform the AJAX get $.get('/plot/', function(data) { //Do whatever you want with the data here }); }); </script> -
Passing context to django-registration's views
I'm utilizing django-registration with a set of premade templates I found on Github for doing a two-step (registration-activation) workflow using HMAC. I want to pass variables like my website's name to the emails sent by django-registration. the activation email sent to a new registrant, for example, or the password change one. The "problem" is I don't directly have access to those views. That's kinda the point of django-registration, you include its path in the urls.py file, and everything works: urlpatterns = [ url(r'^', include('core.urls')), url(r'^admin/', admin.site.urls), url(r'^accounts/', include('registration.backends.hmac.urls')), ] What's the minimum effort way of adding context to those views? I've already created and am successfully passing context to emails in my own views (using context processors): def send_some_email_view(request): msg_plain = render_to_string('email_change_email.txt', context, request=request) msg_html = render_to_string('email_change_email.html', context, request=request) But what about views I didn't create? -

How to get average of 6 first elements in a queryset and annotate the value in Django?
I have 2 models that are something like this: class Foo(models.Model): name = models.CharField(max_length=30) class FooStatement(models.Model): foo = models.ForeignKey(Foo, on_delete.models.CASCADE) revenue = models.DecimalField(decimal_places=2) date = models.DateField() What I want to know is what the average is of the FooStatement revenue for the first 6 dates for each Foo object. Is there any way to achieve this? I was thinking of slicing the first 6 entries (after ordering them), but I cannot seem to get this to work. The statement months all start at different dates so I can't just say that I want all dates that are lesser than 'x'. I'm almost positive the answer lies somewhere in clever annotation, but I just cannot find it. -

Django to create and change mysql database for learning purposes
I am leaning Python programming language. I want to familiarize myself with mysql database as well. I've installed mysql database and Django on my computer. I have Ubuntu 14.04 and python 3.4 installed. I've configured Django settings to use mysql database. I tested Django connection to mysql db and all things work properly. I am a complete newbie with web development. I didn't create my own website and I didn't start developing any web application. My purpose currently is to master creation of mysql database and tables, making changes/migrations/queries, using Django models. Is it reasonable/possible to use Django ORM for work with mysql database without simultaneous development of a web application/local application? As I've said, I don't have my own website. I want just to try using mysql and Django together on my computer in order to get deeper knowledge as to Django and mysql in this respect. -
Django Tweepy Streaming in browser
I want to implement a live streamer in the browser of the Tweeter data. I am using Tweepy library to stream the tweets. class MyStreamListener(tweepy.StreamListener): def on_status(self, status): return status.text This allows me to stream the data to the console, however, I would like to stream and display the data in the browser. What are the steps to achieve that? Should I use Ajax to make a request from time to time in order to populate the data? Is it possible to achieve this by using only the Tweepy library? Thanks, Adrian -

Divs with similar structure would all act when only clicked on one

How to SELECT a field from a LEFT JOIN'ed table/model with Django's ORM (1.11)
Context: Using Django Rest Framework, I've created a ModelViewSet. I'm overriding the list() method to customise the query as explained below. With these models: class Claim(models.Model): permalink = models.SlugField(max_length=255, blank=True, unique=True) author = models.ForeignKey(get_user_model(), db_index=True, on_delete=models.SET_NULL, null=True, blank=True) deleted = models.BooleanField(db_index=True, default=False) collaborators = models.ManyToManyField(get_user_model(), through='ClaimCollaborator', through_fields=('claim', 'user'), related_name='claims') # ...other fields class ClaimCollaborator(models.Model): claim = models.ForeignKey(Claim, db_index=True, on_delete=models.CASCADE) user = models.ForeignKey(get_user_model(), db_index=True, on_delete=models.CASCADE) access_project_only = models.BooleanField(default=True) I'm trying to query Claim to LEFT JOIN ClaimCollaborator and bring back the access_project_only field. ClaimCollaborator is actually an intermediary model handling the ManyToMany relationship between claims and users (collaborators of the claim). So far I have the following (cut down for brevity): class ClaimViewSet(viewsets.ModelViewSet): permission_classes = (IsAuthenticated, ) queryset = models.Claim.objects.all() serializer_class = serializers.ClaimSerializer lookup_field = 'permalink' def list(self, request): result = models.Claim.objects.filter(Q(author=request.user) | Q(claimcollaborator__user=request.user)) print(result.query) return JsonResponse(serializers.ClaimSerializer(result, many=True, context={'request': request}).data, safe=False) Listing produces this SQL: SELECT "api_claim"."permalink", "api_claim"."author_id", "api_claim"."deleted" LEFT OUTER JOIN "api_claimcollaborator" ON ("api_claim"."id" = "api_claimcollaborator"."claim_id") WHERE ("api_claim"."author_id" = 39 OR "api_claimcollaborator"."user_id" = 39) So I'm getting the LEFT JOIN on "api_claimcollaborator" (ClaimCollaborator) just fine, but none of the fields.

Django Viewflow basic questions
Here are few questions i am searching answers for: 1. Difference between BPMN and pure workflow. 2. Can we integrate any system or it has to be Django based? 3. If we want to set up life cycle of a process, Can we get the info which task is stuck at which stage? 4. How much development effort would require to set up a simple workflow? It would be really helpful if anyone could help me with this. -
Django: How to serial a subset of fields in a model instance?
I was wondering if there is a way of serializing (into Json) a subset of all fields in all instance of a model. An example instead of having for a cinema everything that relates to each cinema like seats, screening , movies and so on. Just cinema name and location coordinators. Thank you for your time. Only using vanilla django.
