Many to Many Relationship in django model
I am currently trying to design my django models for the following situations: I have a class that is called User and every user has a unique userid. Now I want to do a ranking, based on the coins a user has. However, I want to make only users that are friends visible to the user when the user views the ranking. Therefore I am defining a class Friends that has a ManytoMany field “isfriend” that contains all the userids that the User is friends with. However, I feel that the way I am trying to do this is not the best way to go. Any suggestions how I should implement this? class User(models.Model): userid = models.CharField(max_length=26,unique=True) coins = models.IntegerField() def __str__(self): return self.userid class Friends(models.Model): isfriend = models.ManytoManyField(User) def __str__(self): return self.isfriend -

Filter Users for field in Django Admin
In my Django Admin I have a field to choose the Author if I create a new Article, but I can choose every User which is registered to my Page.

Django form doesn't show up
I'm working on some project and ended up with some issues. So my form doesn't display itself at all in my template. But I've created another form before and it works as it should! So my code: models.py class Project(models.Model): class Meta: db_table = "project" COLORS = ( ('R', 'Red'), ('B', 'Blue'), ('G', 'Green'), ('Y', 'Yellow') ) project_title = models.CharField(max_length=200) project_color = models.CharField(max_length=1, choices=COLORS) def __str__(self): return self.project_title forms.py class ProjectForm(ModelForm): class Meta: model = Project fields = ['project_title', 'project_color'] views.py def addproject(request): if request.POST: form_p = ProjectForm(request.POST) if form_p.is_valid(): form_p.save(commit=False) return HttpResponseRedirect('/') else: form_p = ProjectForm() context = { 'projects': Project.objects.all(), "form": form_p, 'username': auth.get_user(request).username, } context.update(csrf(request)) return render(request, 'index.html', context) urls.py urlpatterns = [ url(r'^addproject/$', views.addproject, name='addproject'),] index.html <form action="/addproject/" method="post"> {% csrf_token %} {{ form_p.as_table }} <button type="submit" class="btn btn-primary">Add Project</button> </form> -
Passing a Primary Key to a form template
This is an update from this questions, which I will amend if I find a complete answer for this issue - How do I 'Autofill' a CreateView field I have a Artist model, and I'm now trying to add a comment feature to the DisplayView using an ArtistComment modal and a CreateView form on a modal div. I think I'm really close to getting this to work, but I'm having a little issue passing the primary key from my artistdetail.html page to my artistcomment_form.html template. Any help with this, or tips for documentation pages to read would be greatly appreciated. urls.py: url(r'^artist-(?P<pk>[0-9]+)/$', login_required(views.ArtistDetailView.as_view()), name='artistdetail'), url(r'^artist-(?P<pk>[0-9]+)/artistcomment/add/$', login_required(views.ArtistCommentCreate.as_view()), name='artistcomment-add'), views.py: class ArtistCommentCreate(CreateView): model = ArtistComment fields = ['message',] def get_success_url(self): return reverse('events:artistdetail', kwargs={'pk': self.object.artist_id}) def form_valid(self, form, *args, **kwargs): form.instance.author = self.request.user form.instance.artist = get_object_or_404(Artist, id=self.kwargs.get('pk')) return super(ArtistCommentCreate, self).form_valid(form) artistdetail.html: <p id="commentfooter"><a href="{% url 'events:artistcomment-add' artist.id %}">Add A New Comment</a></p> artistcomment_from.html: {% block body %} <div class="col-md-12"> <div class="panel panel-default"> <div class="panel-body"> <form class="form-horizontal" action="{% url 'events:artistcomment-add' pk %}" method="post" enctype="multipart/form-data" onSubmit="CloseModal();"> {% csrf_token %} {% include "events/form-template.html" %} <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <button type="submit" class="btn btn-success">Submit</button> </div> </div> </form> </div> </div> As far as I can tell, where I've entered … -
Django on apache io error
