queryset empty when iterating it
I have a strange error, I have a queryset which apparently have items In [13]: Product.objects.all() Out[13]: <QuerySet [.... In [14]: Product.objects.all().count() Out[14]: 77 But looks like its really empty? In [15]: [p for p in Product.objects.all()] Out[15]: [] I was using it on a rest api view, and noticed it when it was returning empty products but the database has products: class ProductList(generics.ListAPIView): queryset = Product.objects.all() serializer_class = ProductSerializer permission_classes = [ permissions.AllowAny, ] filter_backends = (filters.DjangoFilterBackend,) -
Django ImageField keep original Image ratio while processing
at my models.py i got a class named Post with and ImageField called postcover. I want to save every image in PNG format which is working fine so far but i have no idea how i could keep the actual image aspectio ratio after processing the image because currently i staticaly convert it into 4:3 format ratio while saveing it as 500 by 375 pixels. def save(self, *args, **kwargs): super(Post, self).save(*args, **kwargs) if self.postcover: if os.path.exists(self.postcover.path): imageTemproary = Image.open(self.postcover) outputIoStream = BytesIO() imageTemproaryResized = imageTemproary.resize((500, 375)) imageTemproaryResized.save(outputIoStream, format='PNG') outputIoStream.seek(0) self.postcover = InMemoryUploadedFile(outputIoStream, 'ImageField', "%s.png" % self.postcover.name.split('.')[0], 'image/png', sys.getsizeof(outputIoStream), None) super(Post, self).save(*args, **kwargs) is there any way how i could set a max width and height while i keep the format? -
How to get data from forms?
I have the following view def get_context_data(self, *args, **kwargs): ctx=super(ProductsCreate, self).get_context_data(*args, **kwargs) ctx['special_form'] = SpeciallyPriceForm() return ctx def get(self, request, *args, **kwargs): self.object = None if kwargs.get('slug'): category = Category.objects.filter(slug=kwargs.get('slug')).first() self.initial.update({'category': category}) return self.render_to_response(self.get_context_data()) def post(self, request, *args, **kwargs): self.object = None form = self.get_form() special_form = SpeciallyPriceForm(self.request.POST) print(special_form) if form.is_valid() and special_form.is_valid(): return self.form_valid(form) else: return self.form_invalid(form) forms def __init__(self, *args, **kwargs): self.request = kwargs.pop('request') user = self.request.user provider = Provider.objects.filter(user=user.id).last() self.fields['category'] = ModelMultipleChoiceField(queryset=provider.category.all()) def clean(self): cleaned_data = super(ProductCreateForm, self).clean() cd_category = cleaned_data.get('category') How can I get data from a form (ProductCreateForm)? If I write form = self.get_form(), then I just get a form template, where some data is selected, and some are not (select especially). If I write form = ProductCreateForm(request.POST), then I get an error saying that the request was not found. Perhaps this is due to the fact that I set the request in get_context_data() and work with them in the __init__ method in the forms.py. I process the data in the clean method in the forms.py. -
Is there a way to have both CAS and normal login system in django admin?
I've integrated my django admin application with django-cas-ng. Everything works fine, but after entering the page, django automatically redirects me to the CAS - as it should be doing anyway. However, I would like to have two auth systems - CAS and django. In short, it would be nice if user had a choice. I was thinking about creating another page where user would choose login system (this page would be placed between django login and CAS), but as far as i know it's impossible since admin site points to ' ' and automatically redirects to 'accounts/login' - any change in this mappings would break the system: urlpatterns = [ path('', admin.site.urls), path('accounts/login', django_cas_ng.views.login, name='cas_ng_login'), path('accounts/logout', django_cas_ng.views.logout, name='cas_ng_logout'), path('accounts/callback', django_cas_ng.views.callback, name='cas_ng_proxy_callback'), ] So, is there any recommended way to achieve this? I was thinking about overriding an AdminSite, but I believe this is not good practice. Any help would be highly appreciated! -
How to access Django Model field value?

Editing data without removing previously added. Django using 'forms.Form'
How can I edit data without deleting what has been added before. In my situation, I want to use forms.Form which looks like this class SecondForm(forms.Form): data_1 = forms.ChoiceField(choices=CHOICES, label="") data_2 = forms.ChoiceField(choices=CHOICES, label="") data_3 = forms.ChoiceField(choices=CHOICES, label="") In my views.py id = #some object number if request.method =="POST": second_form = SecondForm(request.POST) if second_form.is_valid(): cd = second_form.cleaned_data object = Valuation(pk=object_id) object.data_1 = cd['data_1'] object.data_2 = cd['data_2'] object.data_3 = cd['data_3'] object.save() return HttpResponseRedirect(reverse('app:valuation_third', args=[forwarding])) else: second_form = SecondForm() In this situation, if my model looks like this: class Valuation(models.Model): data_added_before = models.CharField() data_1 = models.CharField() data_2 = models.CharField() data_3 = models.CharField() Every time a field 'data_added_before' it's cleaned. How to avoid it. So that the information added earlier in this field has been preserved. And new data from the current form added to existing ones. Any help will be appreciated. -
Combining filter and exlude in Django query on related objects gives empty results
I want to do the following query in Django to find car objects that don't exist in manufacturers table and have a specific country code: ids = Cars.objects.all() Cars.objects.filter(group__manufacturer__country=123).exclude(group__manufacturer__id__in=ids) Unfortunately this gives me an empty query result. But executing the filter and exclude query alone gives non empty results where some of the objects are the same (i.e. fullfill both conditions). Therefore I'm wondering how to combine the queries to get the correct subset. I also tried using Djangos Q objects but unfortunately with the same results. If possible I would want to avoid using raw sql. -
Django file object is closing when it moves out of function scope - Python3
I have a below django view from io import TextIOWrapper def get_header_data(file_obj): # perform some operations like text_file = TextIOWrapper(file_obj) reader = csv.reader(text_file) ..... ..... file_obj.seek(0) print(file_obj.closed, "--> Inside get_header_data method") return some_data def upload(request): file_obj = request.FILES["file"] print(file_obj.closed, "--> Inside upload before entering in to get_header_data method") # Get some headers header_data = get_header_data(file_obj) # Facing an error at this point file_obj.seek(0) print(file_obj.closed, "--> Inside upload after returned from get_header_data method") file_obj.seek(0) Output: False--> Inside upload before entering in to get_header_data method False--> Inside get_header_data method True--> Inside upload after returned from get_header_data method ValueError: I/O operation on closed file at line 5 (file_obj.seek(0)) inside upload method The problem here is, in case of python3, the file_obj which I sent to get_header_data from upload method is getting closed by python when the interpreter moved out of upload function(when it got returned). The same code is working fine in Python 2.7, so what could be the problem here and why the file_obj is getting closed when the interpreter moved out of get_header_data method -

How to create a drop down to filter rows in specific columns
I have a table with over 600 rows of data. The columns headers for this table are Name, Office, Address, Primary_Role, Secondary_Role, Other_Role. I would like to create a drop down within my HTML that will have each unique role as an option and will filter through Primary_Role, Secondary_Role and Other_Role. So far I have created a drop down with each unique role as an option but I am not sure how to go about connecting it to the table so that I may get the desired outcome once an option is chosen. HTML Code <select class="filter" data-col="0"> <option value="">None</option> <option value="Assistant">Assistant</option> <option value="2">Associate</option> <option value="3">Compliance Officer for Finance and Administration</option> <option value="4">Compliance Officer for Legal Practice</option> <option value="5">Consultant</option> <option value="6">Designated Partner</option> <option value="7">Director</option> <option value="8">Employee</option> <option value="9">In-house Solicitor</option> <option value="10">Locum</option> <option value="11">Member</option> <option value="12">Non-member Partner</option> <option value="13">Partner</option> <option value="14">Professional Support Lawyer</option> <option value="15">Prosecutor</option> <option value="16">Role not specified</option> <option value="17">SRA-approved manager - Director</option> <option value="18">SRA-approved manager - Member</option> <option value="19">SRA-approved manager - Partner</option> <option value="20">SRA-approved manager - Sole Practitioner</option> </select> <table class="table table-striped" style='width:150%'> <thead> <tr> <th>Solicitor</th> <th>Office</th> <th>Address</th> <th>Primary_Role</th> <th>Secondary_Role</th> <th>Other_Role</th> </tr> </thead> <tbody id="tls_table"> <tr> {% block content %} {% endblock %} </tr> </tbody> </table> </div> -
How to get revision dates for first and last update for multiple objects?
I need to make a bulk query for all instances of SomeModel, annotating them with the date of their creation and last update. Here's what I tried and is terribly slow: query = SomeModel.objects.all() for entry in query: last_updated_date = entry.details.history.last().history_date created_date = entry.details.history.first().history_date csv_writer.writerow([entry.name, last_updated_date, created_date]) How could I optimize the code? I imagine that the problem is that I'm making a lot of SELECT queries, when probably a single bit more complex one would do. -
Django custom FileSystemStorage works in development server but not in Apache server
I have a customized a FileSystemStorage class to allow overwriting existent uploaded files in a subfolder of MEDIA_ROOT when files are uploaded via the admin change interface. However, it works fine in Django development server but in Apache no file is created when the user uploads a file and no errors are reported (neither in Apache error.log or by the Django logging system). The corresponding server folder and sub-folders have the appropriate R/W permissions for both the www-data user and group. Here is the code: class MyFileStorage(FileSystemStorage): def get_available_name(self, name, max_length=None): #pudb.set_trace() return name def _save(self, name, content): full_path = self.path(name) # Create any intermediate directories that do not exist. directory = os.path.dirname(full_path) logger = logging.getLogger('fileupload') if not os.path.exists(directory): try: if self.directory_permissions_mode is not None: # os.makedirs applies the global umask, so we reset it, # for consistency with file_permissions_mode behavior. old_umask = os.umask(0) try: os.makedirs(directory, self.directory_permissions_mode) finally: os.umask(old_umask) else: logger.debug("MyFileStorage::_save: Trying to create directory: %s" % (directory,)) os.makedirs(directory) except FileNotFoundError: # There's a race between os.path.exists() and os.makedirs(). # If os.makedirs() fails with FileNotFoundError, the directory # was created concurrently. pass # If the file already exists we delete it, so we can re-upload a file # with the … -
Django Symmetric Many-to-Many In Both Tables
One thing I found frustrating in Django is the seemingly required asymmetry when defining many-to-many relationships. I teach Django and would really like to find the "most elegant" way to describe and teach many-to-many relationships in Django. One of my students used the technique of putting the class name in as a string in making her many-to-many model. This allows her to avoid less-than-intuitive techniques like related-name. This is my simplified version of her model - the key is that Person and Course are strings, not class names. class Person(models.Model): email = models.CharField(max_length=128, unique=True) courses = models.ManyToManyField('Course', through='Membership') class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) course = models.ForeignKey(Course, on_delete=models.CASCADE) class Course(models.Model): title = models.CharField(max_length=128, unique=True) members = models.ManyToManyField('Person', through='Membership') But while this looks pretty to me, I am concerned that I have messed things up. I have done some basic testing and see no downsides to this style of model definition, but I am concerned that I messed something up that I don't even understand. So I submit this as a question, "What is wrong with this picture?" -

Sentry vs MANAGERS and ADMINS in Django, what's the correct setup?
I'm using Sentry to collect exceptions from my Django application. Recently I learned about the ADMINS and MANAGERS setting for Django, so, I added them to my settings.py. I don't want to miss anything going wrong in my server. Adding them had an unintended consequence, as far as I can see: some exceptions go to Sentry, but some go to the admins (or managers*). To get those exceptions back in Sentry, I need to make ADMINS blank again. Is this the correct setup? Are there any notifications I would lose by having ADMINS blank? Is it possible to set ADMINS and have Sentry still be used to report all notifications? * I'm not sure because I set them to the same value. -

Advice on managing database table triggers when using django model save
We have a legacy SQL Server based database that has triggers set to update created_by, created_on, modified_by and modified_on columns when a row is created and if it is later modified. Default values are set for the created* columns and triggers have been setup for the modified* columns. This has been done to manage creation and update events occurring via different front-ends and even via SQL Server Tool Sets (SSMS) should that occur. I am now building an internal Django based front-end application over some of these tables and am initially using the Django Admin Interface for CRUD based activities over these tables. The issue I have come across is that since the Django Web App is connecting to the database using a Windows Service Account with database privledges the ModifiedBy Trigger is using that servicce user account rather than the WebApp End-User account to identify 'who' has updated a row. I understand why. But would like to know if anyone has been able to somehow force the trigger to use the originating webapp end-user rather than the account used to establish the connection from within Django? The setup is a Windows environment with Apache providing the web hosting for … -
