Two mutually exclusive many-to-many relations
Imagine an online shop. You have goods. Some goods have size, some don't. I've got an orders table id int not null, ... orders_products table order_id int not null, product_id int null, product_size_id int null, ... products table id int not null, ... product_sizes table id int not null, product_id int not null, ... Right now either product_id or product_size_id is not null. In other words, primary key is order_id + (product_id || product_size_id). Not both. In Django's terms that would be: class OrderProduct(models.Model): product = models.ForeignKey(Product, null=True, on_delete=models.CASCADE) product_size = models.ForeignKey(ProductSize, null=True, on_delete=models.CASCADE) order = models.ForeignKey('Order', on_delete=models.CASCADE) amount = models.PositiveSmallIntegerField() class Order(models.Model): products = models.ManyToManyField(Product, through=OrderProduct, related_name='orders') product_sizes = models.ManyToManyField(ProductSize, through=OrderProduct, related_name='orders') ... At least that's what I have right now. But I don't like having two mutually exclusive foreign keys in orders_products table. Or two attributes in Order model. One of which (product_sizes) is probably redundant. So, I probably have to remove product_sizes attribute from the Order model. Is that it? Or should I make product_id not null in orders_products table? And have product_size_id only when the product comes in different sizes? Any other suggestions? I've marked the question with django, python, postgresql tags. But I'm not stuck … -
Libraries available to create a plus button to add data to a view
For the following User model, each User has one primary coid, which identifies the facility they are assigned to. After pulling the User information detail in my profile view I want to have a plus button in my template that will allow me to add an additional coid or as many as the User would like to request because sometime a User is assigned to many coids, but they have one primary. My User model is defined as the following. class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(unique=True) username = models.CharField(max_length=7, unique=True) formattedusername = models.CharField(max_length=11, unique=True, primary_key = True) first_name = models.CharField(max_length=40) last_name = models.CharField(max_length=140) date_joined = models.DateTimeField(default=timezone.now) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_cfo = models.BooleanField(default=False) facility = models.CharField(max_length=140) officename = models.CharField(max_length=100) jobdescription = models.CharField(max_length=140) positioncode = models.CharField(max_length = 100) positiondescription = models.CharField(max_length=140) coid = models.ForeignKey(QVDSSSecurityDimension, null=True, blank = True, db_constraint=False) streetaddress = models.CharField(max_length=140) title = models.CharField(max_length=100) USERNAME_FIELD = 'username' class Meta: app_label = 'accounts' db_table = "user" def save(self, *args, **kwargs): self.formattedusername = '{domain}\{username}'.format( domain='HCA', username=self.username) super(User, self).save(*args, **kwargs); def get_short_name(self): return self.username # REQUIRED_FIELDS = "username" def __str__(self): return '%s - %s %s' % (self.username, self.first_name, self.last_name) My profile view is very simple and I get the coid with … -
How to overcome NoReverseMatch for link inside if statement in the template?
I want to make some value if they exist to be links. In some case value will be None and in some case, it will have a record that user should be able to click at. So in my template, I put it inside the if statement {% if expense_row.noteunit.unit.id %} <a href="{% url 'unit_notes_details' pk=expense_row.noteunit.unit.id %}" class="btn btn-info">{{ expense_row.noteunit}}</a> {% else %} {{ expense_row.noteunit}} {% endif %} But despite the if statement I still get error NoReverseMatch at /expense/list/range/ Reverse for 'extra_notes_details' with arguments '()' and keyword arguments '{u'pk': ''}' not found. 1 pattern(s) tried: ['unit/extra_notes_details/(?P<pk>\\d+)$'] How can I make those occasional links without getting the error ? -

loading a project-wide CSS file inside an app-specific CSS file in Django
I'm working on a Django 1.10.5 project. I have a number of apps, each of which has an app-specific css file which must import a css file common to all the apps. But the import isn't working unless I put the common css file in each app's static folder (defeats the point). In the app template I have <link rel="stylesheet" rel="stylesheet" type="text/css" href="{% static 'app1/css/app1.css' %}"/> And my settings: STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(os.path.dirname(BASE_DIR), "static-storage"), ] STATIC_ROOT = os.path.join(os.path.dirname(os.path.dirname(BASE_DIR)), "static-serve") The common css file is in static-storage/css. I have tried running collectstatic but it does nothing...right now DEBUG=True. Can anybody help? Thanks. -

Django annotation in a loop
I'm trying to create an unknown amount of columns with annotate: def add_daily_usage_record(query, days): for i in days: query.annotate('day_' + i + '_usage'= "doesn't matter" But it doesn't seem to work. Is there any way to give an annotation a name without writing it? or maybe if I have the name of the new column in a variable, is it possible to pass it to annotate? Thank you. -

Django - User registration and login via REST API in the same project
I mainly have two questions. I haven't read this anywhere but, I am wondering whether or not it is a good idea to make it so that all the data that is going in and out of all apps in your project solely depended on REST API calls. So that if you, for instance, want to register a new user. Gather the data from a front-end, with no back-end work, and just send this data as a REST call to you "registration-app" where all validation and back-end work is done. I find this method effective when working in big teams as it makes dependencies even more decoupled, as well as making each part of the project more separated and "clear". My question is, therefore, is this a viable way of developing? Are there any security or performance issues with this? And where can I read more? Thanks Max -
Dynamically accessing a "Friend" model with two foreign-keys to "Profile"
I've created a Friend model that consists of two Profile model instances. The reason for a separate model in the first place is due to the Friend model having special attributes related to the "friend" relationship. In this Friend model, I am also tracking the requester & accepter of the relationship as it is significant to my site--this requires that I have a separate field for each of these, and they are FKs to the Profile model. Here are the two models: class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=True) profile_picture = models.ImageField( upload_to=profile_photo_upload_loc, blank=True, null=True, created = models.DateTimeField(auto_now_add=True) class Friend(models.Model): requester = models.ForeignKey(Profile, related_name='is_requester') accepter = models.ForeignKey(Profile, related_name='is_accepter') requester_asks = models.CharField(max_length=60, null=True) accepter_asks = models.CharField(max_length=60, null=True) With this structure, in instances that I want to retrieve all of the Friend instances that a single Profile is a participant in, I need to make two queries: one for those in which he's the requester and another for those in which the profile is an accepter. The combination of these two querysets gives me the total list of all Friend relationships a Profile belongs to--I need this total list when making things like a message inbox. Attempting to create a message … -

Django rest framework conditionally required fields
I would like to write a drf validator that will mark a field as required based on the value of an other field. For example: class MySerializer(serializers.Serializer): has_children = fields.BooleanField() nb_childs = fields.IntegerField(min_value=1, validators=[RequiredIf(field='has_children', value=True)], required=False) At first i believed the class based validator was the way to do it, by retrieving the value of 'has_children' with a method like this: def set_context(self, serializer_field): print serializer_field.parent.initial_data but the 'initial_data' is not set. Any clue? -

HTML5 video tag does not work on Safari
I'm a coding beginner and currently working on a fitness app. I'm facing the problem that my HTML5 sample video doesn't load in Safari 11, but works perfectly fine with Chrome and Firefox. Here is the html: <video id="VideoElement" width="200" height="160" muted controls src="/static/media/fitness/theraband1.mp4" type="video/mp4"></video> Yet, I don't think that the html is the problem, as I cannot even access the video on Safari with a direct link to the file. In case you want to try by yourself, here is the link: Placeholder video The app is programmed in Python 3 and Django 2. The video can neither be loaded by using the pythonanywhere page nor by my local Django development server. I already searched stackoverflow, but cannot not find a solution. However, I read in some posts that the problem could be related to http headers. -

to_python() and from_db_value() methods overlapping in function?

Reverse for 'create_song' not found. 'create_song' is not a valid view function or pattern name
I have a Django project in which the page that should load to show the album that has just been added, does not. It should go to the primary key for that album (auto generated) with the reference: http://127.0.0.1:8000/music/1/ but instead gives the error: Reverse for 'create_song' not found. 'create_song' is not a valid view function or pattern name. A variant of the same problem, I assume, Is that when I click on the VIEW DETAILS BUTTON (shown below in the index.html) it doesn't load: <div class="caption"> <h2>{{ album.album_title }}</h2> <h4>{{ album.artist }}</h4> <!-- View Details --> <a href="{% url 'music:detail' album.id %}" class="btn btn-primary btn-sm" role="button">View Details</a> <!-- Delete Album --> <form action="#" method="post" style="display: inline;"> {% csrf_token %} <input type="hidden" name="album_id" value="{{ album.id }}" /> <button type="submit" class="btn btn-default btn-sm"> <span class="glyphicon glyphicon-trash"></span> </button> </form> The code for the various sections is below: music/templates/music/album_form.html <div class="row"> <div class="col-sm-12 col-md-7"> <div class="panel panel-default"> <div class="panel-body"> <form class="form-horizontal" action="" method="post" enctype="multipart/form-data"> {% csrf_token %} {% include 'music/form_template.html' %} <!-- how form fields and inputs are laid out--> <div class="form-group> <div class="col-sum-offset-2 col-sm-10"> <button type="submit" class="btn btn-success">Submit</button> </div> </div> </form> </div> </div> </div> </div> </div> {% endblock %} music/views.py from django.views …
