Sorting A Drop Down Menu in Django With Hard-Coded Choices
I have a few drop down menus that are hard-coded into my model. For example: CITIZENSHIP_CHOICES = { (u'Canada', u'Canada'), (u'USA', u'USA'), (u'United Kingdom', u'United Kingdom'), (u'None', u"None of the above"), } COUNTRY_CHOICES = { ('USA', 'USA'),('Canada', 'Canada'),('Israel', 'Israel'),('UK', 'UK'),('Afghanistan', 'Afghanistan'),('Albania', 'Albania'),('Algeria', 'Algeria'),('Andorra', 'Andorra'),('Angola', 'Angola'),('Antigua and Barbuda', 'Antigua and Barbuda'),('Argentina', 'Argentina'),('Armenia', 'Armenia'),('Australia', 'Australia'),('Austria', 'Austria'),('Azerbaijan', 'Azerbaijan'),('Bahamas', 'Bahamas'),('Bahrain', 'Bahrain'),('Bangladesh', 'Bangladesh'),('Barbados', 'Barbados'),('Belarus', 'Belarus'),('Belgium', 'Belgium'),('Belize', 'Belize'),('Benin', 'Benin'),('Bermuda', 'Bermuda'),('Bhutan', 'Bhutan'),('Bolivia', 'Bolivia'),... } SERVICE_LENGTH_CHOICES = { (6, "6"), (12, "12"), (18, "18"), (21, "21"), (24, "24"), (28, "28"), (30, "30"), (32, "32"), (32, "36"), (42, "42") } All of my fields are in the same model in models.py. Each one of the drop down fields looks like this: citizenship = models.CharField(max_length=100, choices=CITIZENSHIP_CHOICES, null=True, blank=True) For some reason though, in my form, the drop downs are in a strange order. I'd like it either to be in the order I entered it in models.py or to order it alphabetically/numerically. 321 Everything I've found online discusses foreign keys, but I'm not using any foreign keys. Any help is much appreciated. -

Alternative to apt-get install packages on pythonanywhere?
I'm trying to deploy a django project to pythonanywhere.

I read that the best you can do is make a request to the pythonanywhere team to have the packages added in future versions. If this is still the case can anyone recommend a host that allows you to install these kinds of modules? -

Django - AJAX POST to API not working but no errors
I am trying to post data to my Django Rest Framework API, I have a GET request which works. The POST request does not work and the error function of the AJAX call is fired. I cant seem to see why it wont work, perhaps my CSRF or CORS headers are incorrect? main.js $(function () { var $items = $('#items'); var $description = $('#description'); var $price = $('#price'); $.ajax({ type: 'GET', url: '/api', success: function(items) { console.log(items) $.each(items,function(i, item){ $items.append('<li> '+ item.pk +', '+ item.Description +', '+ item.Price +'</li>'); }); }, error: function() { alert('Error Loading Items'); } }); $('#add-item').on('click', function() { var order = { description: $description.val(), price: $price.val(), }; $.ajax({ type: 'POST', csrfmiddlewaretoken: "{{ csrf_token }}", url: '127.0.0.1:8000/api/', data: order, success: function(newItem) { $items.append('<li> '+ newItem.Description +', '+ newItem.Price +'</li>'); }, error: function() { console.log(order) } }); }); }); models.py class Item(models.Model): Description = models.CharField(max_length=20) Price = models.DecimalField(max_digits=5, decimal_places=2) def __str__(self): return self.Description Serializers Views.py class ItemListAPIView(generics.ListCreateAPIView): lookup_field = 'pk' queryset = Item.objects.all() serializer_class = ItemSerializer permission_classes = (AllowAny,) -
Getting error when I am trying to fetch my main url patterns
I am a beginner in Django I have created a Django project in that I have included two more application when I did add urls.py file in both Applications both are working well but when I am fetching my main admin URL it is giving an error Page not found (404) Request Method: GET URL: http://127.0.0.1:8000/ the URLconf defined in mac.urls, Django tried these URL patterns, in this order: admin/ shop/ blog/ The empty path didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. when I am fetching this URL in http://127.0.0.1:8000/ i am getting an error it is working for http://127.0.0.1:8000/shop/ here is my main urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('shop/', include('shop.urls')), path('blog/', include('blog.urls')), ] Please suggest me I would appreciate every response in StackOverflow -

how to check if token was expired in models?
I am trying to expire tokens from forgot password requests, but token from PasswordReset becomes NULL after the user updates their password, however, I was thinking on some kind of solution, but I want to expire the token usage after 1 minute or max 5 minutes to meet security requirements, but I also got created_at . how can I set up an is_expire function to invalid the token? if self.token == None: return False do_expire models.py class PasswordReset(models.Model): email = models.ForeignKey(User, on_delete=models.CASCADE) token = models.CharField(max_length=100, null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True, blank=True) updated_at = models.DateTimeField(auto_now=True, blank=True)
