DJANGO - How to send a user from the admin site to a custom view?
I developed an application using the framework provided by Django. I developed CRUD functions using the admin site. However, I would like to redirect a user (if click on a link or button) to another view, a customized one. In my case, if a user is on the change_list template of the admin site and clicks on a button named import file, he will be redirected to a customized view. Change_list template with import file button To do that I developed the following code in the admin.py file concerning the MeasurePoint model. admin.py: @admin.register(MeasurePoint) class MeasurePointAdmin(admin.ModelAdmin): #ALL ATTRIBUTES OF THE CLASS change_list_template = "import/import.html" def get_urls(self): urls = super().get_urls() my_urls = [ path('importFile/', self.importFile), ] return my_urls + urls def importFileView(self, request): context = dict( self.admin_site.each_context(request) ) return TemplateResponse(request, "import/import.html", context) BASE_DIR/'templates/import/importFile.html {% extends 'admin/change_list.html' %} {% block object-tools %} <form action="importFile/" method="GET"> {% csrf_token %} <button type="submit">Import file</button> </form> {{ block.super }} {% endblock %} Nothing works I'm completely lost between the admin class, the customized view importFileView, and the customized template. I have plenty of different errors. I would like to understand more about how everything works and also find a solution to what I want to do. … -

Create multiple unique Owl Carousels for each image object in model
I have a model of image data for a art gallery web app I am making. The homepage displays a grid of images each with its own specific data like image name, description, price etc. When you click on an image, a modal pops up and this is where I want to generate a unique Owl Carousel that will contain more images (front, back, left, right, different angles, etc.) of that painting that was clicked. As I currently have it, no matter which painting I initially click on, only one carousel is being created in the modal which contains every single image that I added in the admin page, which is not what I want. I want to have a separate specific carousel created for each picture object that grabs that object's pictures only. Any ideas? Thank you for the help. Here is my models.py: class Portrait(models.Model): name = models.CharField(max_length= 100) painting = models.ImageField(upload_to= 'paintings') long_description = models.TextField() price = models.IntegerField() short_description = models.TextField() # these are the images that will be displayed in the carousel painting_left = models.ImageField(upload_to= 'carousel_paintings') painting_right = models.ImageField(upload_to= 'carousel_paintings') painting_top = models.ImageField(upload_to= 'carousel_paintings') painting_bottom = models.ImageField(upload_to= 'carousel_paintings') painting_back = models.ImageField(upload_to= 'carousel_paintings') # name the objects … -
Select Multiple In Django Admin Form File Upload
I currently have 2 models: class Item(models.Model): title = Models.CharField(max_length=100) ... class Photo(models.Model): item = models.ForeignKey(Item, on_delete=models.CASCADE, related_name='photos') photo = models.ImageField() I want to be able to have one upload file field in the admin form for the item model, and be able to select multiple images at once, which are all then uploaded to the Photo model with the associated ForeignKey to the item object. In the admin.py file i tried using inline: class PhotoAdmin(admin.StackedInline): model = Photo class ItemAdmin(admin.ModelAdmin): inlines = [PhotoAdmin] class Meta: model = Item But that just gave multiple fields, rather than one field where I can select multiple images and upload them all. -

Adapt global PAGE_SIZE setting in Django REST Framework's browsable API to a different local PAGE_SIZE setting
We are using the Django REST Framework with pagination and a browsable API. The global parameter for the page size in settings.py is set to 10000 in order to get higher performance when accessing the API via HTTP requests which works well: REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": [ "rest_framework.authentication.SessionAuthentication", "rest_framework.authentication.TokenAuthentication", ], "DEFAULT_FILTER_BACKENDS": ["django_filters.rest_framework.DjangoFilterBackend"], "DEFAULT_PAGINATION_CLASS": "rest_framework.pagination.PageNumberPagination", "PAGE_SIZE": 10000, } Now the problem is that this is directly linked to the browsable API which also lists 10000 entries per page. This of course takes very long or even breaks within certain browsers. Is there a way to change this behaviour locally for the browsable API? Thanks in advance! -
Writing to Firestore with Firebase Admin SDK causes app to freeze
I am trying to use Firebase Admin SDK in a Django app using a service account. I followed the instructions as per the official documentation. However, the app gets stuck at the point when Firebase Admin is attempting OAuth2 using Google APIs. My code is as follows: import firebase_admin from firebase_admin import credentials from firebase_admin import firestore cred = credentials.Certificate(key_path)# path to serviceAccountKey firebase_admin.initialize_app(cred) db = firestore.client() doc_ref = db.collection(u'users').document(u'alovelace') # The following causes the app to freeze doc_ref.set({ u'first': u'Ada', u'last': u'Lovelace', u'born': 1815 }) The last message displayed in logs is: 2022-07-06 06:23:38,519 DEBUG Making request: POST https://oauth2.googleapis.com/token The app freezes after that message with no additional info. Any ideas why is this happening? -

Django import-export error reporting for rows
I am using Django Import export for creating a data upload endpoint. However, in case there is an error while uploading the data, I want to know which row numbers have an issue and what the issue is. If there is an error on line 50 and line 60, then it should tell me that both lines 50 and 60 have errors. Currently, if I use raise_errors method then it only shows the error on line 50 and then stops checking. I can do a line-by-line iteration but that method is considerably slow. How can I achieve this? -
