Issue for user from an existing database to login in a Django website
There is my problem, so I need to create a Django app and I think I have to use an already existing database with users in. So I did some research and figured out some issues. So Django store the password with the salt and use it to check the password.But no one says that there will be salt + hashed type password in the database, but we can get read of this issue with the proper check function (related to the encryption function) I think, like this guy Django check_password() always returning False who used bcrypt.checkpw(password, hashedPassword) because in his database passwords are encrypted with bcrypt. The solution proposed was to create a custom authentification backend (even if I don't really see how we can do this I may be able to find out a tuto to do so) but the main issue is that how I can save a user password who register through the Django web site with the same type of hash that the one already existing in the database (with no salt). I'm a really sorry for not be able to give you more precision about how the password are stored in the database because … -
Django structure
I really need a way to print the structure of my Django app So I have an almost finished app and I need to print something like this: ~/projects/project_name/ docs/ # documentation scripts/ manage.py # installed to PATH via setup.py project_name/ # project dir (the one which django-admin.py creates) apps/ # project-specific applications accounts/ # most frequent app, with custom user model __init__.py ... settings/ # settings for different environments, see below __init__.py production.py development.py ... __init__.py # contains project version urls.py wsgi.py static/ # site-specific static files templates/ # site-specific templates tests/ # site-specific tests (mostly in-browser ones) tmp/ # excluded from git setup.py requirements.txt requirements_dev.txt pytest.ini Is this possible? I only can find a way to create an app based in other structure. I need the same but in the other way... Getting the structure of my app... Thanks!!!! -

Django model class with multiple objects from other model class
I want to create a Django model schema to track yacht racing results. This is a highly simplified version, but want to only focus on the relationships and schema first; class Yacht(models.Model): name = models.CharField(max_length=50) class Event(models.Model): event_number = models.IntegerField() class Result(models.Model): yacht = models.ForeignKey(Yacht, on_delete = models.CASCADE) event_number = models.ForeignKey(Event, on_delete = models.CASCADE) result = models.IntegerField(default=0) Question: How would you approach this problem where I want to create an Event, and have it list all the yachts where I can enter their time? I'd like to be able to do this in the Admin 'all at once' instead of going to each yacht. Eventually, I want this to display as a form for a user. For example, if a user clicks on a race event, it loads a page with all the yachts and their time slot. Julien -
Inserting data from an array into a WORD document table

Django not detecting changes in app model
I have created an app called base and added a new model to it. However, whenever I run python3 manage.py makemigrations base It says no changes detected. I have already added my in installed apps INSTALLED_APPS = [ ... 'base.apps.BaseConfig', ... ] And it does have the migrations folder inside the app containing and __init__.py file.

Formset saving any decimal except 0 even though formset is saved and is_valid() passes
I have created a formset to let users log hours on a weekly basis.

refreshing audios makes them impossible to listen to
I want to make a whatsapp like message app but only with audios. I can get them in my vue app the by refreshing regularly the store, to see if new audios arrived: refresh() { this.$store.dispatch("audio/getAudios"); }, }, created() { setInterval(this.refresh, 1000); }, and I display them the following way in my vue app: <div class="audios" v-for="audio in audios" :key="audio"> <audio controls v-if="audio.rooms.split(',').includes(room)"> <source :src= "'http://localhost:8000'+audio.audiofile" type="audio/wav"> </audio> </div> </div> The problem is that by refreshing every second, all audios that are displayed are 're'-displayed and it makes impossible to listen to them. How can I use the v-for differently to avoid this trouble ? -

How can we set a model is as default=0 or defoult=null in django
Two month back I had created two models and it was working well, and now these models have lot of query which is filled by users. It is clear that both models are independent to each other. My previous models.py class State(models.Model): state_name = models.CharField(max_length=300, blank=False) state_code = models.CharField(max_length=100, blank=False,unique=True) @classmethod def get_all_states(self): return State.objects.all() def __str__(self): return self.state_name class College(models.Model): college_name = models.CharField(max_length=300, blank=False) college_code = models.CharField(max_length=100, blank=False,unique=True) university_name = models.CharField(max_length=300, blank=True) def __str__(self): return self.college_name Today I want to design College model according to state wise. If users have selected some state than related college list will come. For this condition I have created below models.py class State(models.Model): state_name = models.CharField(max_length=300, blank=False) state_code = models.CharField(max_length=100, blank=False,unique=True) @classmethod def get_all_states(self): return State.objects.all() def __str__(self): return self.state_name class College(models.Model): college_name = models.CharField(max_length=300, blank=False) college_code = models.CharField(max_length=100, blank=False,unique=True) university_name = models.CharField(max_length=300, blank=True) state_id = models.ForeignKey(State, on_delete=models.CASCADE) @classmethod def get_all_colleges(self): return self.College.objects.all() def __str__(self): return self.college_name In code you can see state_id (in College models) is a foreign key.

Serialize Nested Django models with Many to Many fields
I am trying to serialize a nested django model which is structured as below: class Ingredients(models.Model): ingredient=models.CharField(max_length=264) def __str__(self): return self.ingredient class Step(models.Model): Steps=models.CharField(max_length=264) Ingredient=models.ManyToManyField(Ingredients) def __str__(self): return self.Steps class Recipe(models.Model): user=models.ForeignKey(Users,on_delete=models.CASCADE) recipie_name=models.CharField(max_length=2640) Steps=models.ManyToManyField(Step) def __str__(self): return self.recipie_name I have a main Recipe model which consists of a "number of Steps" and the Steps have "different ingredients" to them. All linked using Many to Many field relation. So far, I have been able to serialize using the below code class IngredientSerializer(serializers.ModelSerializer): class Meta: model=Ingredients fields='__all__' class StepSerializer(serializers.ModelSerializer): ingredient=IngredientSerializer(many=True,read_only=True) class Meta: model=Step fields='__all__' class recipe_serialized(serializers.ModelSerializer): Step=StepSerializer(many=True,read_only=True) Steps = serializers.StringRelatedField(many=True) depth = 2 class Meta: model = Recipe fields = '__all__' Which gives me an output like: { "id": 1, "Steps": [ "Add two bananas together", "Then mix them with apples" ], "recipie_name": "strudel", "user": 1 }, My problem is, I am having a hard time trying to "expand" the Steps as well. As the Steps have ingredients linked to them using a Many to Many relations. So the ideal serializer will have the Step portion further broken down too. Would appreciate any guidance in this regard Thank you -
