Managing Django Model Class for Workout Application
I am building up a workout progress application for a learning project. When setting the class model for the project I came across to schools of thought and I don't know what is the advantages and disadvantages for reach. Here is the simply version: class Exercise(models.Model): name = models.CharField(max_length = 30) def __str__(self): return self.name class Set(models.Model): exercise = models.ForeignKey(Exercise, on_delete=models.CASCADE, related_name='sets') weight = models.FloatField(validators=[MinValueValidator(0)]) repetitions = models.IntegerField(validators=[MinValueValidator(1)]) def __str__(self): return self.exercise.name + ' set #' + str(self.pk) and the second more complicated is: class Exercise(models.Model): # Attributes name = models.CharField(null=False, blank=False, max_length=100) # Methods def __str__(self): return self.name class ExerciseSet(models.Model): # Attributes for exercise sets exercise = models.ForeignKey(Exercise, null=False, blank=False, on_delete=models.CASCADE) sets = models.ManyToManyField("my_gym.Set", related_name="sets") number_of_sets = models.IntegerField(null=False, blank=False, default=3) # Methods def __str__(self): return str(self.exercise.name) + " - " + str(self.number_of_sets) + " sets" class Set(models.Model): # Attributes reps = models.PositiveIntegerField(null=False, blank=False, default=0) weight = models.DecimalField(max_digits=5, decimal_places=2) # Methods def __str__(self): return ( str(self.reps) + " " + " x " + str(self.weight) + " " ) The requested project outcome is to just to set the progress of the workout logging the weight and reps of each excercise.

How to add constant fields to Wagtail form builder
I have created job application form with Wagtail form builder. Now I need to add some fields which are meant to be constant and appear on the application form without the need for the admin user adding them each time a new job application form is created. For instance, I have the following: Name Email Phone Number [admin created form fields] How to instantiate the first 3 fields and populate FormField db table with the data before the JobApplicationForm page is created? My data as below: FormField( question = 'Enter Your Name', label = 'name', field_type = 'singleline', required = True, ), I have the feeling a signal has to be created, but I don't know how? -
Applying different CSS style for each element in For Loop - Django
I'm building a blog with Django and i'm trying to apply my static design to dynamic HTML templates. I have several CSS classes for diffrenet card types (regular, medium and large), and i'm builing a posts page that should display all posts from all classes. I'm trying to find a solution for looping through every post and applying different CSS class accordingly. To sum it up: i have a posts list in my db i want to loop over all the posts and assign different pre-defined CSS class to different posts (meaning the "class" should be different for some posts, some should have class "card" and some "large-card", etc) Any help? Here is a sample of the html code i refer to: {% for post in post_list %} <div class="card"> ... </div> {% endfor %} -

DJango not excuting Javascript loaded from a file

Use TokenAuthentication AND SocialAuthentication from AllAuth
I've created a new Django Rest API thanks to Django Rest Framework and I want to use two type of authentication : TokenAuthentication AND SocialAuthentication with two providers Facebook and Google. Token authentication is success (with this syntax : Authorization: Token <token>. However, I can't get it to work with the SocialAuthentication. When I get the access_token from my POST in GoogleSocialLoginView, I can't use it to login in my others API call headers (I use an authenticated permissions for others CRUD calls). My syntax for social authentication is : Authorization : Bearer <token> So the users are registered successfully in database, but they can't authenticated us to the API after.

How does Django work with react combined?
I just started out with Django, I got a litte bit experience in React though. So, there is one topic that confuses me a litte... If I google how Django works with React, I mostly see 2 ways. The first on works by putting React right into Django and the second is by using a Rest-API. I Think that the two ways follow different approaches in terms of that the first way is for using React directly in the backend (so as a part of the backend) and the second option uses React in the Frontend and communicates via the API with the backend. IF I am wrong at this point then please show me the right way... So, IF I am right, what is the goal of using React inside of Django, if you already have the possibilities of using variables, functions or even classes? Just because of JS instead of Python? Or do I overlook something? -

Django REST Framework Serializer - how to save InMemoryUploadedFile to disk?
At my Django RestAPI I can upload an image, instead of saving this image at an ImageField referenced at the database I just want to save it to the disk without any further processing. Currently, my code looks like this: class UserAvatarUpdateSerializer(ClearNullSerializer, serializers.ModelSerializer): user = serializers.PrimaryKeyRelatedField(read_only=True, default=serializers.CurrentUserDefault()) avatar = serializers.ImageField(write_only=True, required=True) class Meta: model = get_user_model() fields = ('id', 'user', 'avatar',) read_only_fields = ('id', 'user') def save(self, **kwargs): new_avatar = self.validated_data['avatar'] directory = (str(MEDIA_ROOT) + "tmp/") filename = str(uuid.uuid4()) new_avatar.save(os.path.splitext((directory + filename))[0] + '.png', optimize=True, format='png') But I'm running into: AttributeError: 'InMemoryUploadedFile' object has no attribute 'save' So my question is how can I save a InMemoryUploadedFile to disk? -
How to access data in Docker from my Django app?
I am new to Docker so I wonder if I have 2 containers, a streamer that pushes data to the queue and vernemq which is the message queue. How can I access the data to work with it in my django rest api app? I was wondering is there a way to export or the data and create a separate database in django with it or it's not how it works? Or is there a way to directly access the data in docker from django app. Note the django rest api app is not in a docker Image. -
Make first name field unique for User in django
I am making a web app with django and I need to make the Users first name unique. I have searched around and it doesnt seem like there is a simple way to do this. The reason i need the first name to be unique is because i am using the first name field as a spotify username field because it makes it convenient because i can use the user creation form.
