aldjemy/sqlalchemy engine timeout with google cloud
I have a django app where I am using graphql, it's running on google cloud with 60 minutes timeout. The DB is POSTGRES. At some point I had to use sqlalchemy to upload a large csv file to the databse, and graphql is not fast enough for that. 20 minutes into the upload I get the following error: ERROR in app: Exception on / [GET] and Traceback (most recent call last): File "/layers/google.python.pip/pip/lib/python3.9/site-packages/urllib3/connectionpool.py", line 703, in urlopen httplib_response = self._make_request( File "/layers/google.python.pip/pip/lib/python3.9/site-packages/urllib3/connectionpool.py", line 449, in _make_request six.raise_from(e, None) File "<string>", line 3, in raise_from File "/layers/google.python.pip/pip/lib/python3.9/site-packages/urllib3/connectionpool.py", line 444, in _make_request this is how I am uploading the file: with pd.read_csv("prices.csv", chunksize=500000) as reader: for prices in reader: engine = get_engine(connect_args={'connect_timeout': 3600, 'pool_size': NullPool}) with engine.begin() as conn: conn.exec_driver_sql( f"CREATE TEMPORARY TABLE {temp_table_name} AS SELECT * FROM {table_name} WHERE false" ) prices.to_sql(temp_table_name, conn, if_exists="append", index=False) conn.exec_driver_sql(stmt) engine.execute(f'DROP TABLE "{temp_table_name}"') I do not get the error when i run the code locally and I can't find any reference to the 20 minutes anywhere on google cloud, except for the function timeout, which is set to 60 minutes in my case. -

Displaying an image stored in a Django database
I have a website dedicated to pets (dead ones), and I have some stock images in the database stored under the pet using a manytomany field (so, any number of pets can be in an image, and a pet can have any number of images associated with it--seems logical so far). I am trying to display the pet photos in any way at all in one of the templates. My problem is, I have NO IDEA what the correct syntax for iterating over a context_dictionary data structure I have made to store pets and pet photos for the purpose of accessing in the associated template file. I am having to do this because I think (correct me if I'm wrong) a view can only have one associated model, and I need a few models, their data, to display in one view. So. It is what it is. I think it's probably about time I showed some of my code. Here is one after another: pet_profile/models.py from django.db import models from django.utils.crypto import get_random_string import uuid from django.urls import reverse class PetPhoto(models.Model): slug = models.SlugField(max_length = 5, primary_key = True, blank = True, null=False) title = models.CharField(max_length = 255) id = … -
Incorrect floating label positioning on responsive input form
I've created a form using Django, Crispy Forms and Bootstrap. At screen widths above 575px the form and labels look as expected with fields of the correct width and floating labels in the correct position, however at screen widths below 575px the floating labels appear in the wrong position. I'd appreciate any guidance as to how I can make the floating labels remain in the correct position relative to the input field regardless of screen width. Expected: >575px Unexpected: <575px I believe this happens because, in order to force the responsive resizing of the input fields, I manually amended the CSS to reduce the the field width to 85% at screen widths lower than 575px by using a media query as follows: CSS .form-floating { position: relative; } .form-floating > .form-control, .form-floating > .form-select { height: calc(3.5rem + 2px); line-height: 1.25; } .form-floating > label { position: absolute; top: 0; left: 0; height: 100%; padding: 1rem 0.75rem; pointer-events: none; border: 1px solid transparent; transform-origin: 0 0; transition: opacity 0.1s ease-in-out, transform 0.1s ease-in-out; } @media (max-width: 575px) { .form-floating > .form-control, .form-floating > .form-select { display: block; width: 85%; padding: 0.375rem 0.75rem; margin: 0 auto; -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: … -

Html Form Posting Values to Django Backend only when submitted twice, or rather hit back to form and then submit again

Creating multiple objects in DRF failing with error "'int' object has no attribute 'pk'"
I use ListCreateAPIView to create new instances of the Review model. Running my code in debug mode I can see that once the line serializer.is_valid(raise_exception=True) is executed, the code fails with the error AttributeError: 'int' object has no attribute 'pk'. models.py class App(models.Model): name = models.CharField(max_length=200, unique=True) identifier = models.CharField(max_length=200, unique=True) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) image_url = models.URLField(blank=True, null=True) image_file = models.ImageField( upload_to='images/app_icons/', blank=True, null=True) def __str__(self): return self.name def save(self, *args, **kwargs): """ Custom save method which fetches the image_file from the image_url, if image_file does not exist """ if self.image_url and not self.image_file: image = urllib.request.urlopen(self.image_url).read() self.image_file.save(self.name + '.jpg', ContentFile(image), save=False) super().save(*args, **kwargs) class Review(models.Model): comment = models.TextField() rating = models.IntegerField( validators=[MinValueValidator(1), MaxValueValidator(5)]) review_id = models.IntegerField(unique=True) review_date = models.DateTimeField() review_author = models.CharField(max_length=200) app = models.ForeignKey( App, on_delete=models.CASCADE, related_name='reviews') serializers.py class ReviewListSerializer(serializers.ListSerializer): def create(self, validated_data): items = [Review(**item) for item in validated_data] return Review.objects.bulk_create(items) class ReviewSerializer(serializers.ModelSerializer): class Meta: model = Review fields = '__all__' list_serializer_class = ReviewListSerializer views.py class ReviewList(generics.ListCreateAPIView): """Retrieves lists of reviews and creates new reviews Default list method is modified to: - Return count of data under key 'count' """ queryset = Review.objects.all() serializer_class = ReviewSerializer def create(self, request, *args, **kwargs): data = request.data … -
Django CBV with DropzoneJS and django-storages backend for multifile upload form won't validate
I am using django-storages with (GCS backend) and would like to be able to use DropZonejs to upload multiple files to a model that has a FK. This is where I've gotten so far. It always comes back what Bad Request, form not valid. Assuming you're getting to this view from a detail view that includes a pk for 'thing'. (the backend works just fine uploading through django admin) Models.py class Thing(models.Model): name = models.CharField(max_length=25, verbose_name="name") def image_dir_path(instance, filename): # specify file naming return 'folder/{}/{}'.format(instance.thing, filename) class Image(MetadataFields): thing = models.ForeignKey(Thing, on_delete=models.DO_NOTHING, related_name="things", verbose_name=_("Thing")) my_image = models.ImageField(upload_to=image_dir_path, null=True, blank=True, verbose_name=_("My image")) Forms.py class ImageForm(forms.ModelForm): class Meta: model = Image fields = '__all__' widgets = { 'my_image': forms.ClearableFileInput( attrs={'multiple': True}), } Views.py class ImageUploadView(FormView): form_class = ImageForm template_name = "appname/_uploadimages.html" def post(self, request, *args, **kwargs): form_class = self.get_form_class() form = self.get_form(form_class) files = request.FILES.getlist('file') # thing= self.kwargs.get('pk') if form.is_valid(): for uploaded_image in files: # image = models.Image.objects.create(thing=thing, my_image=uploaded_image) image = models.Image() image.my_image = uploaded_image thing_instance= models.Thing.objects.get(id=self.kwargs.get('pk')) image.thing= thing_instance image.save() return HttpResponse('Image upload succeeded.') return HttpResponseBadRequest("Image upload form not valid.")
