Migrate form to modelform
I wrote following form: class VoteForm(forms.Form): choice = forms.ModelChoiceField(queryset=None, widget=forms.RadioSelect) def __init__(self, *args, **kwargs): question = kwargs.pop('instance', None) super().__init__(*args, **kwargs) if question: self.fields['choice'].queryset = question.choice_set class VoteView(generic.UpdateView): template_name = 'polls/vote.html' model = Question form_class = VoteForm def get_queryset(self): return Question.objects.filter(pub_date__lte=timezone.now()).exclude(choice__isnull=True) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # Check duplicate vote cookie cookie = self.request.COOKIES.get(cookie_name) if has_voted(cookie, self.object.id): context['voted'] = True return context def get_success_url(self): return reverse('polls:results', args=(self.object.id,)) def form_valid(self, form): redirect = super().form_valid(form) # Set duplicate vote cookie. cookie = self.request.COOKIES.get(cookie_name) half_year = timedelta(weeks=26) expires = datetime.utcnow() + half_year if cookie and re.match(cookie_pattern, cookie): redirect.set_cookie(cookie_name, "{}-{}".format(cookie, self.object.id), expires=expires) else: redirect.set_cookie(cookie_name, self.object.id, expires=expires) return redirect The problem is that the normal form does not represent a object, like ModelForm and does not have the save() method. But I can't figure out how to migrate the form. There is no choice or choice_set field: class VoteForm(forms.ModelForm): class Meta: Model = Question #throws exception fields = ('choice',) widgets = { 'choice': forms.RadioSelect() } How can the form from above be reproduced as a model form? -
Django Crispy Form Submit Button
I am trying to use Crispy Forms to make my forms look good.

I have read the cripsy form documentation and I can't seem to find anything wrong with my implementation. Everything except for the submit button is displayed. Any ideas? -

send django message from a template file
Is it possible to set message using django message framework from inside a template file? {% if not userIsLoggedIn %} <a href="{% url 'login' %}" class="btn btn-primary">Buy</a> {# I want to send message to the user who click this buy button on the login page #} {% elif not game_bought and game.price != 0 %} <form action="/buy" method="POST"> <input class="btn btn-primary" type="submit" value="Buy"> </form> {% endif %} I can think of a hackish way of doing it by using query string, but it would be nice if I could use django's message framework. -
Serializing a Django form using django-rest-framework-braces
I have written a form in Django and I want to pass this form to my front-end client in JSON format.

I would appreciate any guidance. Thanks, -

How to structure a many to many django model with
I have a issue with how to structure my django model. I have a User model and an Account model. The User can be in multiple accounts. Each User should have a key for each Account. I want to be able to get the key associated with the account and user combination. User 1 is in Account A and B. If I query for Account A and User 1 I should get key1 and if I query for B and 1 I should get key2. keys = {AccountA: key1, AccountB: key2} I'm just confused on how I can store this data. I know I could serialize json and store as a Text Field. But I think that will be messy. I want to be able to regenerate the keys if needed. What is the class User(models.Model): accounts= models.ManyToManyField(Account) keys = models.TextField() OR class User(models.Model): accounts= models.ManyToManyField(Account) keys = models.ManyToManyField(AnotherModel?) Something else? Caveats: I cant use hstore or jsonfield. I'm on django 1.7 -
Python - Creating new model objects leads to updating previously created objects
I'm using Django to create a model called CampaignProfile, then each logged in user can fill in a form to build such an object, and have all of their 'CampaignProfile's displayed on their personal dashboard. What I've found is that when I fill in this form then a new CampaignProfile object is not created like I need, but instead the information entered (title, etc) replaces the first CampaignProfile made. I'm struggling to understand why the model object is being updated as opposed to creating a new object. Models.py: def get_file_name(instance, filename): return ('uploads/%s_%s' % (str(time())).replace('.','_'), filename) class CampaignProfile(models.Model): user = models.OneToOneField(UserModel, related_name='campaignprofile', on_delete=models.CASCADE, null=True) campaign_title = models.CharField(max_length=50, verbose_name='Title') campaign_dt_created = models.DateTimeField(auto_now_add=True, verbose_name='Date Created') campaign_dt_updated = models.DateTimeField(auto_now=True, verbose_name='Date Updated') campaign_docs = models.FileField(upload_to=get_file_name, verbose_name='Files', blank=True, null=True) slug = models.SlugField(unique=True, blank=True) class Meta: verbose_name = 'Campaign Profile' def __str__(self): return 'Campaign Title: ' + self.campaign_title + ' - ' + str(self.user) def save(self, *args, **kwargs): if self.user is None: # Set default reference self.user = UserModel.objects.get(id=pk) super(CampaignProfile, self).save(*args, **kwargs) Forms.py class NewCampaignForm(forms.ModelForm): campaign_title = forms.CharField(min_length=1, max_length=80, label='Campaign Name', required=True, widget=forms.TextInput(attrs={'autofocus':'autofocus'})) campaign_docs = forms.FileField(label='Attach .png and .docx files to your campaign', required=False, widget=forms.ClearableFileInput(attrs={'id':'fileupl'})) class Meta: model = CampaignProfile fields = ['campaign_title', 'campaign_docs'] def clean(self): β¦ -

permissions.AllowAny DRF
I am using Django, DRF and Angular. Since I started working on my API I have been managing to connect and retrieve data from my db to Angular. All of a sudden today I started getting a 401 unauthorized error. In my settings.py under REST_FRAMEWORK I have this: 'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.IsAdminUser',), So at first I thought It was because I was logged out of the admin section of django so I logged in but nothing changed. IN responce to this I changed the line of code above to this: 'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.AllowAny',), After this I can now get access to the data and the API is returning information fine. Question Is there harm in setting permissions.AllowAny? What potential problems might this expose me to? Furthermore, can anyone possibly provide me with possible reasons why all of a sudden I am getting the 401 unauthorized error. Fiddler gives me this extra information {"detail":"Authentication credentials were not provided."} -

Could not find a version that satisfies the requirement tensorflow==1.0.0 in Heroku
I am deploying a django project using heroku cloud platform. I have added the dependencies in requirements.txt file. However when I push to heroku master, I get the following error: Collecting tensorflow==1.0.0 (from -r /tmp/build_bc8be989466414998410d3ef4c97a115/requirements.txt (line 17)) remote: Could not find a version that satisfies the requirement tensorflow==1.0.0 (from -r /tmp/build_bc8be989466414998410d3ef4c97a115/requirements.txt (line 17)) (from versions: ) remote: No matching distribution found for tensorflow==1.0.0 (from -r /tmp/build_bc8be989466414998410d3ef4c97a115/requirements.txt (line 17)) remote: ! Push rejected, failed to compile Python app. remote: remote: ! Push failed remote: Verifying deploy.... remote: remote: ! Push rejected to what-the-image. remote: I am using Django v 1.10 and python 2.7. Where would I be going wrong?
