Permission denied to upload folder Django
I am trying to upload images in django. I have set static directory in settings.py STATIC_URL = '/assets/' STATIC_ROOT = os.path.join(BASE_DIR, "assets") SITE_ROOT = os.path.dirname(os.path.realpath(__file__)) STATICFILES_DIRS = ( os.path.join(SITE_ROOT, 'assets'), ) here is my model image Field doImage=models.ImageField(upload_to='doImage/%Y/%m/%d',verbose_name='Do Image') Now when i tried to upload it then i faced permission denied 13 error. I had tried command chmod with 777 to give a permissions to folder sudo chmod -R 777 assets i also had tried change user of file using command sudo chown -R root:root assets But both things didn't worked for me. So anyone have idea that what's going wrong let me know. -
Django Count rows with duplicate values
I am working on counting rows with duplicate values in a django Model and running into a little hitch. I have looked at this question Django Select Rows with duplicate Values and the solution is perfect. But my question is, What if I want to Count the rows and group them according to: Name of the duplicated row, and how many times it has been duplicated, instead of just displaying the name of the repeated rows. my code so far: views.py dupes = Application.objects.values('school_name').annotate(Count('id')).filter(id__count__gt=1) query = Application.objects.filter(school_name__in=[item['school_name'] for item in dupes]) The query variable returns a queryset with the Applications that have duplicate values for the field school_name while this line: repeated_names = Application.objects.values('school_name').annotate(Count('id')).order_by().filter(id__count__gt=1).values_list('school_name', flat='true') returns a list of the duplicated school names. What I expect is something like: (school_name=school_name_1, count=2), (school_name=school_name_2, count=3).. etc. -
how to fix footer at the bottom of responsive page
I have a responsive page. I want to fix footer at the bottom of this page. I have searched a lot and find many working solution. However, all of them are failed when it comes to the responsive page.

Django: How to prefetch related for a model instance. Perhaps by wrapping in a queryset?
I use Django rest framework and I have decent nesting in my model relations. I'm working on optimizing my queries. Many of my functions consume or manipulate a single instance of model and it's often further downstream in the data flow that it turns out I need some prefetching. One classic instance of this is with DRF serializers. Here's an example. @api_view(['GET']) def fetch_user_profile(request): profile = request.user.profile # has many nested relationships return Response(UserProfileSerializer(profile).data, status=status.HTTP_200_OK) # this ends up taking many queries I've seen some solutions suggesting passing queryset with prefetch_related in the context although I haven't been able to get a full picture on how that would work (I've only found a couple of places that discuss it partially, might open a whole other question on that). An easy fix (and one that would generalize beyond serializers) would be if I can have a wrapper function to wrap my instance in a queryset and then call prefetch on that, passing it into the serializer. Something like: def queryset_wrap(instance): return type(instance).objects.filter(id=instance.id) I'm wondering if there's a better way to do this. -
I/O on Closed File error in Django When generating thumbnail of uploaded image
I'm building a django site, and when I upload an image (the model is Photo) through the admin view, I want to generate an arbitrary thumbnail of it and save that off to a Thumbnail Image Field. The thumbnails are generating nicely, but when the Photo model tries to save, I get that I've tried to perform an I/O operation on an object that's closed: "I/O operation on closed file". The stack trace traces back up to the call to the superclass, so I think it's made it through the generate_thumbnail function. What am I doing wrong? Any help would be appreciated. from PIL import Image from io import BytesIO from django.core.files.base import ContentFile class Photo(models.Model): photo=models.ImageField(upload_to='photos/',blank=True) thumbnail = models.ImageField(upload_to='thumbs/', editable=False, null=True) def save(self,*args,**kwargs): if self.photo: self.generate_thumbnail() super(Photo, self).save(*args,**kwargs) def generate_thumbnail(self): img =Image.open(self.photo) img.thumbnail([consts.THUMB_HEIGHT,consts.THUMB_WIDTH],Image.ANTIALIAS) name = os.path.basename(self.photo.name) thumb_name, thumb_ext = os.path.splitext(name) thumb_ext=thumb_ext.lower() outname="thumb_"+thumb_name+thumb_ext if thumb_ext in ['.jpg','.jpeg']: filetype='JPEG' elif thumb_ext == '.gif': filetype='GIF' elif thumb_ext=='.png': filetype = 'PNG' else: raise Exception("Failed to generate thumbnail.

DRF serializer check undefined field
I used drf and also used serializer to check user input. Here is my serializer.py class BoardSerializer(serializers.Serializer): user_id = serializers.IntegerField(required=True) body = serializers.CharField(required=False) And use it like this. serializer = BoardSerializer(data=request.data) if serializer.is_valid(): .... It seems that doesn't check undefined field. For example, If I request with {'user_id':1, 'body': 'abc', 'akak': 1}, is_valid() do not catch field 'akak' and just pass the data. Is there any function to validate if fields is defined in serializer or not? Thanks. -

Django migrations not applying after moving from test PC to production server/DB
I am unable to run the inital migrations in my django project on my production server. I started working on my Django app on my computer with a sqlite db. I was able to run the initial migrations (auth, admin, etc.) and they created tables in my sqlite db with no problem. I was also able to get tables created for the models in my app. Today I moved the same django project to my webfaction server via git and I am unable to get my MySQL db populated with tables at all. As soon as I created the db, I ran migrate but it said there were no migrations to apply. I tried deleting the migrations folder in my app, but that didn't help at all, probably because there is no django_migrations table to compare any migrations against. It seems as if the initial migrations are stored where django is installed. This is not part of my git repo, so anything there that might indicate whether the migrations have been made wouldn't be pulled over. I tried running python manage.py migrate admin And the same thing with auth, but it did't work I'm not really sure what the proper … -
Datatables not working unless port is specified (proxy_pass)
Data tables seem to only be working when navigating directly to my Django web application at http://server.com:9001 even when I've proxied all HTTP traffic to 9001. Screenshot when viewing from http://server.com:9001/stores Screenshot when viewing from http://server.com/stores The datatable just simply refuses to work. What's even more odd is I have another data table at /servers doing the same thing, but an identical table at /closed-stores works consistently (I've refreshed dozens of times in a row to try and get it to break & it won't). Each of these tables' JS is simply $('#table-id').Datatable(); but I'll leave this out as its clearly working, so I believe its my Nginx.conf maybe, or something to do with Django? I'll note as well there are 0 errors in console during all scenarios.

Is there any way to bypass the server my Django site is hosted on when uploading files, and just immediately upload to S3 instead?
I am using boto3 to upload massive media files (2GB+) from my Django website to an s3 storage bucket. My issue is that when uploading a file larger than 2.5MB - the connection is immediately timed out and no debug information displays I assume what is happening is that Django is using the temporary file upload handler, but the temp file handler won't work on the server the Django app is running on (pythonanywhere free tier). This works flawlessly locally, because it just has to copy to the OS, not the server. I would like to skip the web server so I am not using all the storage/bandwidth s3.upload_file needs the local path of the file in order to be able to upload it to S3, the only way I could find to do that is grab the temp_path of the file. # method to chunk the upload process if file is over 2.4MB def s3_multipart_upload(f, video_id): # our server path file_path = "media/" new_folder = str(video_id)+"/" file_name = f.name server_path = file_path + new_folder + file_name # the file gets copied to ~/tmp/ so grab that path local_path = f.temporary_file_path() # create s3 client connection s3 = boto3.client('s3', settings.AWS_S3_REGION_NAME, …
