Django+Haystack+Whoosh, no models being indexed, no results returned in search
I have a haystack search implementation using the whoosh backend in django 1.10. I've followed the "Getting Started" documentation page and have implemented everything I can see there, however, when I run ./manage.py update_index It will show me Indexing 0 posts And when I run a test search I will get no results.

Django model serialization only returns primary key for foreign key

Django: combining method and class inside views to share same url
I'm working on Django project where I have an app which has a page with a drop down and a chart that is generated from data (which is queried from the database and passed into an API url). I'm using class based views and APIView and have a get method which is creating a response to pass some Json data into a url. I have the following class in my views.py set up and working. views.py class ChartData(APIView): authentication_classes = [] permission_classes = [] def get(self, request, format=None): data =#code to generate data via query goes here return Response(data) In order have access to this data, I have my url set as: url(r'^display/api/chart/data/$', views.ChartData.as_view()), This data from the API is used to generate a ChartJS graph in my template html of this app. The chart is set up so that it seeks the Json data from the url display/api/chart/data/ and uses Ajax to populate itself. I also have another method in the same views file as follows: views.py def DropdownDisplay(request): items= #query from database if (request.method == 'POST' and request.is_ajax()): print(request.POST) return render(request, 'DisplayData/Display.html',{'dropdown':items}) This method is used to generate a dropdown in the page.

Django 1.4 - query iteration using fields stored in a dictionary
I had a huge registration table with 112 fields. For a particular search I want to compare 17 fields & assign colors to variable say 'clrSelected'. My code is : reg = Regisration.objects.filter('some condition').order_by("name") for r in reg: if r.name=='abc': clrSelected='#fff' if r.type=='1': clrSelected='#000' if r.appl=='10': clrSelected='#c1ff51' if r.code=='': clrSelected='#60c5f7' if r.qlty=='first': clrSelected='#f99334' ... ... I want to access the field name from a dictionary like this flds = {'1':'name', '2':'type', '3':'appl', '4':'code', '5':'qlty',...} And use it something like this if r.flds['1']=='abc': clrSelected='#fff' if r.flds['2']=='1': clrSelected='#000' ... How could i use the fields as above. I am using django 1.4 & python 2.7 -
How to set specified kwargs to url outside for loop?
I have some links in template. <ul> {% for cat in cats %} <li><a href="{% url 'c_index' cat.slug %}">{{ cat.name }}</a> {% endear %} </ul> <ul> {% for type in types %} <li><a href="{% url 'ct_index' cat.slug type.slug %}">{{ type.name }}</a> {% endear %} </ul> Of course, I can't access second link because I can't use 'cat.slug' outside {% for cat in cats %} loop. But I want to set "cat.slug" to second link without using {% for cat in cats %} loop. How can I do this? For example, using template tag? -

Does Django require the full web-setup to run professionally on non-internet devices?
This is either a really good or really stupid question, but I find its worth asking -- I'm making a Django app that runs on a device as an interfaces. Is there any reason to think I could just use the python manage.py runserver and go no further? Or is there a better way to do this? Installing the full web-bundle for local-network-devices seems excessive, hence my question. (Perhaps there is not a great deal of overhead using the full-web-setup -- I dunno). This is currently on the Raspberry pi, but for prototype purposes. The end-product will not necessarily be Pi. -

How to implement notification service using Django Channels in a chat application?
I am working on chat application based on django, but for real time notifications and chatting, I plan on using django channels. The problem is that apart from documentation there are hardly any resources available to get in-dept knowledge of the concepts. Can anyone suggest a way to implement notifications in my application as when a user receives a message, he/she gets notified(using websockets concept). Also, I plan on using channels as a way to display which of the users are currently online. Models are as follows : class Person(models.Model): user = models.OneToOneField(User) name = models.CharField(max_length=50) contact = models.CharField(max_length=12) online = models.IntegerField(default=0) def __str__(self): return self.name class Dialog(models.Model): author = models.ForeignKey(Person,related_name="self") reader = models.ForeignKey(Person) def __str__(self): return self.author.name + " - " + self.reader.name class Message(models.Model): dialog = models.ForeignKey(Dialog) sender = models.ForeignKey(Person) text = models.TextField() def __str__(self): return self.sender.name + " : " + self.text I have been stuck with this problem for a while now. I would be grateful if anyone can suggest a solution. Thanks in advance. -

Django Oauth Toolkit Invalid Credentials With Special Characters
I am using Django Oauth Toolkit with DRF. When authenticating, Django Oauth Toolkit works successfully when there are no special characters in the username. However when a special character exists, the authentication fails. The documentation explicitly states the username can contain special characters. url = 'http://myurl.com/o/token' data1 = { 'username': 'asdf', 'password': 'asdf', 'grant_type': 'password', 'scope': 'read' } data2 = { 'username': 'asdf@asdf', 'password': 'asdf', 'grant_type': 'password', 'scope': 'read' } headers = { 'content-type': 'application/json', } auth = ( 'client_id', 'clietn_secret' ) user = User.objects.get(username='asdf') # returns object user2 = User.objects.get(username='asdf@asdf') #returns object response1 = requests.post(url, data=json.dumps(data1), headers=headers, auth=auth) #returns 200 response2 = requests.post(url, data=json.dumps(data2), headers=headers, auth=auth) #returns 401 '{"error_description": "Invalid credentials given.", "error": "invalid_grant"}' I have tried: Removing all special characters when creating the account, then removing the special characters when logging in Using client_credentials for the scope Using re.escape for both registering and logging in Using urllib.quote for both registering and logging in I must be missing some fundamental concept. Why does creating a new Django user with a username containing a special character affect OAuth? Is there a workflow to create accounts and then authenticating them when using special characters? -

Models.py: class Question(models.Model): user= models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.TextField() content = models.TextField() date_published = models.DateTimeField(auto_now_add=True) last_modified = models.DateTimeField(_('Last Edited'), auto_now=True) slug = models.SlugField(max_length=255) class Question_Follows(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) count = models.IntegerField(default=0) views.py class QuestionDetailView(DetailView): model = Question slug = 'slug' template_name = "questions/question_detail.html" def get_context_data(self, **kwargs): context = super(QuestionDetailView, self).get_context_data(**kwargs) context['now'] = timezone.now() #obj= Question_Follows.objects.filter(id=question.id) #context['follow_count'] = Question_Follows.objects.filter(id='question.id') #obj.count <----- none of these have worked so far. return context detailview.html: <div id="question_container"> <input type='hidden' id="{{ object.id }}" name="id"> <--- tried this as a way to get question id --> <h1>{{ object.title }}</h1> <p>{{ object.content }}</p> <p>Published: {{ object.date_published|date }}</p> <p>Date: {{ now |date }}</p> <button class="follow"><span id='follow-span'>Follow| <strong id='follow-count'>{{ follow_count }}</strong> </button> </span></button> I'm having problems 'collecting' the right question once the like button has been pressed and also showing the right number of likes for the question i.e the follow count for each question. -
how to properly refactor this function into another file? django
I have a try and except which is used super often, so I am thinking of taking it out and make it into a function in other file but I cannot seem to make it work. Can someone please give me a hand? this is the code which I use really really often try: user = get_object_or_404(User, email=data['email']) except Exception as e: print(e) return json_response_message(False, e.message) I tried making it into another file and did it this way def auth_token(data): try: return get_object_or_404(User, email=data['email']) except Exception as e: return JSONresponse({'status': False}) then when I call auth_token I did it this way in another way and of course I did import it user = auth_token(data) I can understand this would then return me JSONresponse({'status': False}) and I tried using raise and it would tell me that I can't use JSONresponse Can someone give me an idea how this can be done? -
Django forms validating boolean values and numbers as string
I have a form as shown below, class UserForm(forms.ModelForm): name = forms.CharField(max_length=255) tagline = forms.CharField(max_length=255) privacy = forms.CharField(max_length=10) description = forms.CharField(max_length=2000) home_id = forms.CharField(max_length=32, required=False) class Meta: model = User fields = ['name', 'tagline', 'privacy', 'description'] and when I pass any field as a boolean or numerical value (say, name=True) , the form validates it form.is_valid returns True while if I skip one field (say name=None), the form says the form is invalid. The form works, but not for a boolean value for any field. Form also validates correctly for floats, lists and dicts. What am I doing wrong? The same happens for a form.Form without mentioning a model.
