I'm monitoring the temperature for different locations. I have the data stored in a model and have set my views.py, but I would like to refresh the table every 5 minutes. I'm new to ajax and dajaxice, how can I write the function so it displays in html? this is my views.py: def temperature(request): temperature_dict = {} for filter_device in TemperatureDevices.objects.all(): get_objects = TemperatureData.objects.filter(Device=filter_device) current_object = get_objects.latest('Date') current_data = current_object.Data temperature_dict[filter_device] = current_data return render_to_response(

Short question. I have two models: class Author(models.Model): name = models.CharField(max_length=250) class Book(models.Model): title = models.CharField(max_length=250) author = models.ManyToManyField(Author) One view: def filter_books(request): book_list = Book.objects.filter(...) How can I display in template next content: Authors in selected books: Author1: book_count Author2: book_count ... Let's build the query step by step. First, get the authors who have a book in book_list . authors = Author.objects.filter(book__in=book_list) The trick is to realise that an author will appear once for

For example: class TestModel(models.Model): ref1 = models.ForeignKey(RefModel) text1 = models.TextField() class TestModelForm(ModelForm): class Meta: model = TestModel fields = ('text1') I only allow the user to input text1 field, but when I redefine the post method of my view, I also want to set the ref1 value, how should I do that? I wish I can let TestModelForm has the ref1 field but don't let user modify it, then I can modify the value of request.POSt in post method, and pass it to TestModelForm, is that possible? You can use HiddenInput as ref1 widget: class TestModelForm(ModelForm):

I have a table with data looking like this: |Country|State|City |Street| |-------|-----|-----|------| | USA | AZ |city1| str1 | | USA | AZ |city1| str2 | | USA | AZ |city2| str1 | | USA | AZ |city2| str3 | | USA | MN |city3| str4 | | MEX | CH |city4| str5 | | MEX | CH |city4| str6 | What is a proper way to convert this into nested dictionary? I expect the result looking like this: nested_dict = { 'USA':{ 'AZ':{ 'city1':['str1','str2'], 'city2':['str1','str3'], }, 'MN':{ 'city3':['str3','str4'], }, }, 'MEX':{ 'CH':{ 'city4':['str5','str6'], }, }, } You can use a nested defaultdict : from

I'm trying to use UUIDField as a primary key for a model. I'm using CreateView for creating objects for this model. Anytime I browse to the url for creating one of the objects I get the error: badly formed hexadecimal UUID string The stack trace shows the error occurs here, where value is created: /home/conor/django/venv2/local/lib/python2.7/site-packages/django/db/models/fields/__init__.py in get_db_prep_value return name, path, args, kwargs def get_internal_type(self): return "UUIDField" def get_db_prep_value(self, value, connection, prepared=False): if isinstance(value, six.string_types):

In my template I have used for loop for some fields <div class="register_div"> <p>Title:</p> <p>{{ form.title }}</p> </div> <div class="register_div"> <p>Upload Images :</p> <p>{{ form.image }}</p> </div> {% for item in product %} <div class="register_div"> <p>{{ item.Name }} <input type="text" name="custom[{{item.id}}]"/></p> </div> {% endfor %} <div class="register_div"> <p>Price:</p> <p>{{ form.price }}</p> </div> As code shows there is one field which using for loops if that field has three records then in the form it shows three text boxes so that user can feed data to all three fields,

I was wondering how I would be able to create an object in a database based the URL a user is going to. Say for example they would go to /schedule/addbid/1/ and this would create an object in the table containing the owner of the bid, the schedule they bidded on and if the bid has been completed. This here is what I have for my model so far for bids. class Bids(models.Model): id = models.AutoField("ID", primary_key=True, editable=False,) owner = models.ForeignKey(User) biddedschedule = models.ForeignKey(Schedule) complete = models.BooleanField("Completed?", default=False) The biddedschedule
