How do I display content cards evenly spaced including margin sides using flexbox
HTML <section class="cards"> {% for m in mcontent %} <div class="card"> <div class="top"> <div class="year">{{m.Year}}</div> <div class="wish_icon"><a href="#" class="add_to_wishlist">wishicon</a></div> </div> <div class="middle"> <div class="img-container"><img src="{{ m.Image.url }}"></div> </div> <div class="bottom"> <div class="charge">{{m.charge}}</div> <div class="list">{{m.list}}</div> </div> </div> {% endfor %} </section> CSS .cards { display: flex; justify-content: space-around; flex-wrap: wrap; flex-direction: row; } .card { width: 250px; height: 350; border-radius: 10px; box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2); background-color: white; margin-left: 30px; margin-right: 30px; margin-top: 30px; margin-bottom: 30px; } what it looks like: [1]: https://i.stack.imgur.com/KWiLm.png what it should look like: [2]: https://i.stack.imgur.com/t2WuA.png So Ik that I can solve this with justify-content: flex-start; but that leaves me with unwanted space on the right side and I'm kinda lost, any help is appreciated, Thnx! -

How does Almofire "upload" images from Swift to a backend?
I am trying to upload images from Swift to my Django backend so that I can store them in Google Cloud Storage and access them as "foreign keys" in my database models in django. There seems to be a built in library to bridge Django models and Google Storage https://django-storages.readthedocs.io/en/latest/backends/gcloud.html. Reference upload image to server using Alamofire. Before sending an image to the backend, the image is converted into a UIImageJPEGRepresentation. How exactly is Alamofire then sending the image via "multipartFormData"? Is it simply sending the raw UIImageJPEGRepresentation as a string? I am asking this because I need to somehow convert this image data I receive in my backend and store it in a Django model and simultaneously upload it to Google Storage. From the documentation: >>> class Resume(models.Model): ... pdf = models.FileField(upload_to='pdfs') ... photos = models.ImageField(upload_to='photos') To store a local file to cloud storage and at the same time in a model field: >>> obj1.pdf.save('django_test.txt', ContentFile('content')) >>> obj1.pdf <FieldFile: tests/django_test.txt> Would something like this work for an image sent from Alamofire? >>> obj1.photos.save(<Insert whatever was sent from Alamofire>) If so, how do you access the data sent from Alamofire? -

How to structure and connect a python project (not a web application) with Django project?
I have a processing engine built in python and a driver program with several components that uses this engine to process some files. See the pictorial representation here. The Engine is used for math calculations. The Driver program has several components. Scanner keeps scanning a folder to check for new files, if found makes entry into DB by calling a API. Scheduler picks new entries made by scanner and schedules them for processing (makes entry into 'jobs' table in DB) Executer picks entries from job table and executes them using the engine and outputs new files. All the components run as separate python process continuously. This is very in efficient, how can I improve this? The use of Django is to provide a DB (so the multiple processes could communicate) and keep a record of how many files are processed. Next came a new requirement to manually check the processed files for errors so a UI was developed for this. Also the assess to the engine was to be made API based. See the new block diagram here Now the entire thing is a huge mess in my opinion. For start, the Django now has to serve 2 different sets … -

Given my two models, Deck and Flashcard: class Deck(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=255) class Flashcard(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) deck = models.ForeignKey(Deck, on_delete=models.CASCADE) question = models.TextField() answer = models.TextField() I want to show the details of a particular deck, e.g. list of questions and answers for that deck. So in my Deck model, I've got the following function: def list_flashcards(self): fc_list = Flashcard.objects.filter(deck=self).values_list('question', flat=True) return fc_list Now in my html template, if I use: {{deck.list_flashcards}} I get: <QuerySet ['first', 'second','third'] In other words, I get the right items, just not in the right format. How can I get this as a 'normal' list? For example, when I use... {{deck.list_flashcards.0}} <br> {{deck.list_flashcards.1}} <br> ...it works. But I won't know how many cards a user will have, and also it's of course not efficient. What I want to do is something like this: {% for fc in fc_list %} Question: {{fc}} {% endfor %} But it doesn't work - nothing appears on the website. Should I be adding this to my view for it to work? -
Django Admin: create button for foreign key of a foreign key
Sorry, for the bad title. I was not sure how to phrase it. Background: So mainly I am creating this eCommerce website which has a model called product: class Product(models.Model): name = models.CharField(max_length=80) price = models.DecimalField(decimal_places=2, max_digits=6) on_sale = models.BooleanField(default=False) sale_price = models.DecimalField(decimal_places=2, max_digits=6) short_description = models.TextField() description = models.TextField() in_stock = models.BooleanField(default=True) category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True) tags = models.ManyToManyField(Tag) def __str__(self): return self.name This model is liked to by an attribute model using foreign key as so: class Attribute(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) title = models.CharField(max_length=20) def __str__(self): return self.title finally, the attributes model is linked to by AttributesOption model using a foreign key as so: class AttributeOption(models.Model): value = models.CharField(max_length=20) attr = models.ForeignKey(Attribute, on_delete= models.CASCADE) price = models.DecimalField(decimal_places=2, max_digits=6, null=True) on_sale = models.BooleanField(default=False) sale_price = models.DecimalField(decimal_places=2, max_digits=6, null=True) short_description = models.TextField(null=True) description = models.TextField(null=True) in_stock = models.BooleanField(default=True) def __str__(self): return self.value So essentially, a product can have multiple attributes such as colour, size, type etc. Similarly, an attribute can have multiple values such as pink, blue, red, green etc. (I'll later code it so that if there is a value for on_sale, price etc. in the attribute value it will override the main product value.) Now to …
