How can I thumbnail images in serialization of Django REST Framework?
I recently jumped into Django REST Framework. Before using it, I thumbnailed images using django-imagekit. Like you see the models below, it worked well, so I used original size images from image and thumbnailed size images from image_thumbnail. models.py class Image(models.Model): ... image = ProcessedImageField(null=True, blank=True, upload_to=image_path, processors=[Thumbnail(1000, 1400)], format='JPEG') image_thumbnail = ImageSpecField( source='image', format='JPEG', options={'quality': 40}) ... The problem is I can't use image_thumbnail in my serializers. I can use image, but image_thumbnail throws an error message A server error occurred. Please contact the administrator. serializers.py class ImageRandomSerializer(ModelSerializer): class Meta: model = Image fields = ('image', 'image_thumbnail', ) Can I not thumbnailed images from models.py in serializers.py? Should I thumbnail them with some Django REST Framework thumbnail tool? -

How to add an GenericRelation field in a form in Django

Modify image uploaded in django 2.0 before the image is saved to disk
I have a model with a FileField for document uploads (e.g. images, pdfs, or videos). I use this line in my Document model: storage_file_name = models.FileField('File name', upload_to=unique_file_path) and in unique_file_path I change the name of the uploaded document to a unique file name. I find that I will be uploading some tiffs, which I need to change to jpeg or something that a browser can easily display. I have been looking for the best way to convert the uploaded tiff file to jpeg. Is there a way to do it before the image is saved to the disk, or is the best way to use a @receiver(models.signals.post_save, sender=Document) and save the converted image over the saved tiff image? At this point I am only using the admin pages and not any custom views (except by customizing the admin pages). Thanks! Mark -

Django missing migrations file - how to sync db with master file?
one of my fellow developers checked out from master and created new models for our website. He ran makemigrations, then ran migrate which obviously created the tables we wanted. However, he never committed his changes to github and he altered the production database. So when I went in to add a table today, when I ran makemigrations it the terminal listed several tables that I knew already existed...I was like "YOLO!" and ran the migrate command anyways and it puked. So, since the migrations file isn't in my migrate folder, django thinks it needs to create those tables...then it goes to create them and pukes because they're already there. The other developer is out of town visiting family and can't commit the file. How do I get this set straight? I think I need to run ./manage.py migrate my_app --fake But I don't completely understand what that does so I don't want to take the YOLO route and really mess things up... -

django queryset aggregation count counting wrong thing
This is a continuation question from: Django queryset get distinct column values with respect to other column My Problem: Using aggregate count in django counts the wrong thing in the queryset, or as far as I can see something that is not even in my queryset. What I did I used: queryset.order_by('col1', 'col2').distinct('col1', 'col2').values('col2') to get the values of col2 of a model where all the rows have a distinct pair of values in (col1, col2). There is an example in the link above. I printed my queryset and it looks good, I have [{col2: value1}, ... , {col2: value1},{col2: value2}, ..., {col2: value2},...]. I now want to count how much each value appears in the queryset I got. I do this using aggregation count. I have: a = {'count': Count(F(col2), distinct=False)} queryset.annotate(**a) I tried this with ``distinct=True` as well but no luck I would expect to get [{col2:value1, count: num1}, {col2:value2, count: num2} ...]. Instead I get [{col2: value1, count: num11}, {col2: value1, count: num12}, ... ,{col2: value1, count: num_1n}, {col2: value2, count: num21}, ... ,{col2: value1, count: num_2n}, ...] Where as far as I can tell num11, ...., num_1n are the amount of lines value1 existed in col2 … -
Missing filterset object in context using django-tables2 and django-filter
I have been trying to create a view with filter-bar and a table of users. I am using django-tables2 and django-filter libraries and I have this view: class UserListView(SingleTableView, FilterView): model = User template_name = 'admin/users.html' table_class = AdminUserTable filterset_class = UserFilter paginate_by = 10 However the problem is that there is no filterset object in data-context sent to template, nor there is no filterset object in self of UserListView. I was trying to replace SingleTableView, FilterView to FilterView, SingleTableView and then it passes filterset object under filter key in context to the template, however in this case when I visit a page with no filter parameters in url it shows empty list. But If I put a ?search= in url it shows all users and filtering works fine. -
Django Debug Toolbar 1.10 (and 1.10.1) Not Showing

Django queryset get distinct column values with respect to other column
I am using django orm and I am trying to get all the values of a column, but only if a different column is unique with respect to it. Its hard to explain, so here is an example: q | a | 1 w | s | 2 e | a | 3 q | a | 4 w | s | 5 e | a | 6 I would like to get all the values that are in column 2 but if they also have the same value in column 1 don't take duplicates. So in this case I want to get [a,s,a]. (column 3 only serves to show why these duplicates don't get merged in the first place). What I tried: I tried grouping by values of columns 1 and 2 and taking the distinct value of it, thus I would end up with: q | a w | s ---> which is actually given as [(q,a),(w,s),(e,a)] e | a with the code: queryset.values(col1,col2).distinct() but I only want the second column so I then added .values(col2). The problem with that is the distinct gets applied to the results of the second values as well as the first, so …
