Django accessible from the local pc where Django stored, but not accessible from another local device
I'm building an application using React TSX for the front-end side and Django for the back-end side. So the application is working properly and it is accessible from my local PC by localhost:5000 because the application is stored on that PC, the React TSX app and the Django backend files. But whenever I try to access the application from other local devices, my Mobile or Tablet, I keep getting Network Error from the catch of axios. I have tried a lot of ways but I'm still not able to grant access from Django or React TSX. So any help will be great guys. Thanks. settings.py .......... ..........

Django sorting and determine the position of user
I am trying to determine the rank of participants in terms of total_votes. Below is the code that sorts all the participants in terms of total_votes and date_joined. I have added date_joined as well while sorting because if there are 5 participants with same total_votes then it will sort them in terms of date joined which means if two participants A and B have same votes but participant A joined the competition earlier then participant A will be in front of participant B. ranked_data =participants.objects.order_by('-total_votes', 'date_joined') Now how can i determine the rank of participant with participant id. I have the participants model as below: class participants(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) fullname = models.CharField(max_length =50) email = models.EmailField(max_length =50, default='') display_image = models.ImageField(upload_to=path_and_rename, max_length=500, help_text="Select display image") date_joined = models.DateTimeField(null=True, blank=True) dob = models.DateTimeField(null=True, blank=True) gender =models.CharField(max_length =10) total_votes = models.IntegerField(default=0) Can someone one suggest me to rank participants in appropriate way? -

Django - Where should signals be placed?
collection.models.py: class Collection(Model): items = ManyToManyField(Item) ... item.models.py class Item(Model): state = OneToOneField('ItemState') ... class ItemState(Model): item = ForeignKey('Item') ... Structure explanation: An item only has a single state at a time, but the client wants to track its state history. I want to write a signal that creates a new state when a Collection is created. Due to circular imports, I am separating my signals from my models. Now my question is do I write the signal for the above mentioned under collection_signals.py or item_state_signals.py. My guess is that both will work, but what would be the logical place to search for the above mentioned signal? I assumed collection since Collection is the sender, but then again this is about creating states and various models will be creating states (e.g. when a new item gets created that should trigger a new state as well) -
Download button security
I'm just wondering how secure my method is to have downloadable files. I have a model for uploading files and have <a> tag download button in my template served from a@login_required view.

How to display a selected post on a comments form

Django: render list of forms
I'm new to Django (and still learning python...) I'm having an issue with form rendering and I'm clearly doing something wrong.. I'm able to create few forms in form.py and able to have them render as I want (case1 in bellow core). But when I want to bundle all forms into a list, then I can't get the render to work. I thought this would be an issue with passing the form to html but I doubt that as the print of the variable form in view.py shows no string in case#2 (but does show proper html in case1). So I believe my issue is elsewhere? Help would be appreciated! >more form.py from django import forms class AppConfig(forms.Form): # case1 working: # myform1 = forms.CharField(required=False, initial="test1") # myform2 = forms.CharField(required=False, initial="test2") # case2 not working: myform = [ forms.CharField(required=False, initial="test1"), forms.CharField(required=False, initial="test2")] >more views.py from django.http import HttpResponse from django.shortcuts import render from django import forms def app_config_view(request, *args, **kwargs): form = AppConfig(None) print("form looks like:") print(form) return render(request, "app_config.html", {"form":form}) >more app_config.html {% extends 'base.html' %} {% block content %} <h1>APP config page</h1> <form method="post" action="."> {% csrf_token %} <input class="btn btn-primary" type="submit" value="Save" name="save"> <input class="btn btn-primary" type="submit" … -

inline YAML fixture for ManyToMany relation
I have two models with one containing a ManyToManyField relationship to the other and I know how to create separate YAML fixtures for them: - model: books.Author pk: 1 fields: name: Author One books: [1, 2] - model: books.Book pk: 1 fields: title: Book One release_date: 2010-01-01 00:00:00+00:00 author: 1 - model: books.Book pk: 2 fields: title: Book Two release_date: 2011-01-01 00:00:00+00:00 author: 1 But I want to populate these fixtures inline with natural keys so that I don't have to do as much bookkeeping with PKs.

Django CreateView with pk from different unrelated model
I have a django CreateView where users can create new words. I also have an unrelated Song model, where users can choose to add words from the lyrics of the songs. So I've created a separate CreateView for this, so that I can have a different success url. The success url should go back to the song where the user was browsing. But I am struggling to figure out how to pass the pk of this particular object to the CreateView of a different model. This is my special CreateView: class CreateWordFromSong(LoginRequiredMixin, generic.CreateView): template_name = 'vocab/add_custom_initial.html' fields = ("target_word","source_word", etc.) model = models.Word from videos.models import Song def form_valid(self, form): self.object = form.save(commit=False) self.object.user = self.request.user self.object.save() return super(CreateWordFromSong, self).form_valid(form) success_url = reverse_lazy('videos:song-vocab', kwargs={'pk': song_pk) #how to get song_pk? Everything works when I replace song_pk with the actual pk. I overwrite form_valid so that the user can be saved with the new object. Perhaps there is a way I can alter this so that I can also get the song_pk? I've played around with it a bit, but without luck. I get the song_pk from my url: path('song/<int:song_pk>/', views.CreateWordFromSong.as_view(), name='create-song'), So I should have access to it. But when I … -

User Specific Profile Page with CRUD functionality in Django
I'm a Django newbie and for the last few weeks, I've followed some foundational tutorials on app creation with user login, logout, and authentication functionality. In each tutorial, the CRUD functionality is enabled across all users but the content is aggregated on the application homepage. For example, in the blog creation tutorial, you can register a user, login to the application, and generate a blog post, however, the blog post is rendered on the application homepage where any user can view that content. Can anyone point me towards a resource (docs or tutorial) that explains how to create an isolated content page for the user? Meaning, once the user registers, logs in and creates a blog post, it will only populate in the user's personal 'home' page and is not viewable (nor can it be edited) by the other users. Thank you. -
How to see all possible query sets of a model in django
I have two models like below in django class User(AbstractBaseUser, PermissionsMixin): first_name = models.CharField(....) last_name = models.CharField(_(....) email = models.EmailField(...) class VcsToken(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) as you can see VcsToken is related to User, and a user can have many VcsToken, So how do I get all the VcsTokens of a User. Similarly I have many one to many relationships from user to other models, so How do I know their reference name? (I know its a set but how do I know the set name? ) Is there any way to list the query set names for a model.
