OneToOne connection between User and Profile in Django
I am creating an app in django in which after user model is created, via the signal I create a profile: from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() But as far as I feel, this does not guarantees me that profile id always equals user's one Is there any smart way to do this safer? I think about creating a signal which will delete profile model after user one and opposite, but I still feel that not all cases are covered -
Django login user never come true

How to make Django using Pillow to crop only new image?
I can make Django crop images, but I got a problem. When I go to change form to update one of the images, all images got cropped again and again after every new save - which means all images get smaller and smaller. How to make Django only crop new images and leave old images alone? Each of my images got a crop count field - when set to 0 the image could be cropped and if set to 1 the image could not be cropped. Each image also got a created_date field which automatically generated a timestamp. Can any of these extra fields be used to create a condition in which an image won't get cropped twice when a whole model got updated? Example: product 1 = got image_1, image_2, image_3, -- image_1 got crop_count and created_date fields, same goes for all other images. -- I want is to go to image_1 to update it with a newer image, and I don't want to see image_2 and image_3 got cropped - but only image_1 gets cropped. How? I know how to use signal in Django, so should this be post-save or pre-save? -

Making a dropdown list based on an IntegerField's value django
I want to display the Nombre_des_Emplacments IntegerField in the Rayons model as a dropdown menu in the References Model below, for example the number inputted is 44, I want for the dropdown menu to show the numbers between 1 and 44 as choices to select from, and after a number is selected and saved after adding the References, it has to be taken out from the choices and not show up again when adding a new Reference, Exp: if 20 is selected next time the dropdown menu will show all the numbers from 1 to 44 except 20 just so you know the Nombre_des_Emplacments IntegerField is also suppossed to be dependent on Rayons.Nom from the same Model which will also be a dropdown menu So when adding a reference and I get to the Emplacment field, I select the Rayon and depending on what I selected the second dropdown menu will show the correlated numbers with that Rayons here's the code: models:py class Rayons(models.Model): Nom = models.CharField(max_length=100, blank=False, null=True) Nombre_des_Emplacments = models.IntegerField() def __str__(self): return self.Nom class References(models.Model): Ref = models.CharField(max_length=255, blank=False, null=True) Designation = models.CharField(max_length=100, blank=False, null=True) Indice = models.CharField(max_length=100, blank=False, null=True) Emplacment = models.ForeignKey(Rayons, blank=False, null=True, on_delete=models.CASCADE) Client … -

How to easily find patch target in unittest?
I have the following module structure within a Django app: subscriptions - api - views.py - serializers.py - tests test_some_view.py - models.py - signals.py In models.py I have a GooglePlayOrder model, and in signals.py I have a signal: @receiver(post_save, sender=GooglePlayOrder) def save_google_play_order(sender, instance, created, **kwargs): pass The GooglePlayOrder instance is being created in a serializer GooglePlayOrderSerializer from api/serializers.py, which is called by some GooglePlayOrderView in api/views.py. And now I want to run a test from api/tests/test_some_view.py, where I want to mock the save_google_play_order signal. Unfortunately, this implementation does not work, as I (AFAIK) should follow the imports for patching something: @patch('subscriptions.signals.save_google_play_order') def test_normal(self, mock): So, how should I understand in this case what exactly I should use as a target of patch decorator? -

ValueError: Unknown metric function: top_2_accuracy. Please ensure this object is passed to the `custom_objects` argument
I'm working on a CNN classification project, and I've used the top 2 Accuracy (top_k_categorical_accuracy) as the accuracy matrix for training. the function in the model notebook is: from tensorflow.keras.metrics import top_k_categorical_accuracy def top_2_accuracy(y_true, y_pred): return top_k_categorical_accuracy(y_true, y_pred, k=2) then I used it as model.compile(optimizer = Adam(lr = 4e-3), loss='categorical_crossentropy', metrics=['accuracy', top_2_accuracy]) Now I need to load the model to use it in an application I tried to use this code: model = tf.keras.models.load_model('model.h5') but an error occurred while loading Unknown metric function: top_2_accuracy. Please ensure this object is passed to the `custom_objects` argument.
