Cookie is not set in ajax calls from code but working fine in console
I am working on ajax call using jquery and django framework. I am getting 403 error in chrome when doing ajax call from website. But when I do ajax call from console, I am getting different response. Also, it is working in firefox. Here is my code $.ajaxSetup({ xhrFields: { withCredentials: true }, crossDomain: true }) $(document).ajaxSend(function (event, jqxhr, settings) { settings.data += '&csrfmiddlewaretoken=' + window.getCookie('csrftoken'); if (settings.type == "POST") { jqxhr.setRequestHeader('X-CSRFToken', window.getCookie('csrftoken')); }; }); $.ajax({ 'type':'POST', 'dataType':'json', 'url': url, 'data': data, }).always((data)=>{}) Can anyone tell me what is the problem? -
Does Django Cache Clear Itself After Expiration
I am currently working with Memcache and Django to cache data requested from an external API, so I don't overwhelm their servers. Currently my code looks like this: # CACHE CURRENT PRICE cache_key_price = str(stock.id)+'_price' # needs to be unique cache_key_change = str(stock.id)+'_change' # needs to be unique cache_keychange_pct = str(stock.id)+'_changePct' # needs to be unique cache_time = 60 * 5 # time in seconds for cache to be valid data = cache.get(cache_key_price) # returns None if no key-value pair if not data: delayed_price, change, changePct = get_quote(stock.ticker) cache.set(cache_key_price, delayed_price, cache_time) cache.set(cache_key_change, change, cache_time) cache.set(cache_keychange_pct, changePct, cache_time) context_dict['delayed_price'] = cache.get(cache_key_price) context_dict['change'] = cache.get(cache_key_change) context_dict['changePct'] = cache.get(cache_keychange_pct) I'm a bit new to caching and I am curious if after 5 mins the cache will clear itself and data will return None triggering the if not data: bit of code to get updated data. Thanks in advance for any help! -

How to modify how Djongo ArrayModelField is shown in Django Admin
I'm experimenting with Djongo right now. So far a great project! What I don't like yet is the way ArrayModelField fields are integrated in the Django admin. I am missing something like an add-button. At the moment only one additional empty inline Form is shown for the nested model. Is there a possibility to add new inline models with an "add-button"? -

django-money vs custom solution with minor currency
I'm just about to decide if I should use the django-money package or have my own solution, which allows me to work with minor currencies. I've read a lot that if you work with money you should always use minor currency or it's the better solution (I want to use stripe and I've seen that they are also handling the money in the minor currency). In order to get the minor unit I want to use this package (iso-4217). Does anyone have experience which solution is better? -

django {% get_current_language as LANGUAGE_CODE %} and session['_language'] are not equal until reload
In my app I can change the language by the following: from django.utils.translation import LANGUAGE_SESSION_KEY # LANGUAGE_SESSION_KEY is "_language" ... def my_view(request, my_lang=en): request.session[LANGUAGE_SESSION_KEY] = my_lang ... context = {"mysession": session} return render(request, "mytemplate.html", context) This works mostly as expected. However, the direct response of this view renders still in the previous language despite the session variable is set correctly. In other words the following template gives imho contradictory output: {% load i18n %} {% get_current_language as LANGUAGE_CODE %} <b>Debug:</b> current_language: {{ LANGUAGE_CODE }} session_variable: {{mysession|get:"_language"}} Note that, to access the attribute _language beginning with an underscore I have to use a custom filter, see this answer. Django-Output: Debug: current_language: en sessionvariable: de All {% trans ... } statements are handled to the (outdated) content of LANGUAGE_CODE, which is annoying. After changing the language the uses expects an immediate effect. If I refresh the page or load a different view, then the new language is used correctly. Do I understand something wrong? How can I achieve that the current_language is set correctly in the immediate response. -
Django Non-Managed Models - Querying from JSON file instead of Database
I want to have model that don't need to be created in database as table but use data from other sources like json files and other model objects. So I am using Non-Managed Model. This model is being created dynamically as described here in the docs Now Let me explain how I want to create the fields in this non-managed model. I have a json file that defines what fields should be in model, Let's call it contact-model.json. fields in this json file are mapped to django fields and dynamic model is created. This part is done. { 'model_name': 'Contact' 'fields': { 'name': 'CharField', 'email': 'EmailField' } } Now I have model that is storing all data related to above contact-model.json. Code for that model is given below class GenericAnswer(models.Model): answer = JSONField() model = CharField(default='Contact', max_length=30) And value of that asnwer would be { 'name': 'Adil Malik', 'email': 'sample@email.com' } What I want to do is that when I fetch Contact.objects.all(), It should return objects fetching from GenericAnswer based on model name, in this onctext, it is Contact. Can I do it. If Yes, Plese Explain How ???? -

Django, Hosting using Pycharm
I have to host a Django website onto the private server at my workplace. I'm using MySQL as the database (Through Wamp). The machine I'm using has Windows Server 10 installed on it. Is it advisable to use Pycharm's Deployment option? If so, What options and settings do i use? Is there any way i can map my IP address to a URL so that the users dont have to remember my IP Address? Is there any alternate/effective method that i could use? Also, I've disabled the IIS on the system so that i could use WAMP. {I faced a lot of issues downloading the database version that's compatible with all the files and WAMP was the easiest option i could find. It also comes with phpmyadmin, which helps as well. Also, Keep in mind that I'm still trying to figure everything about about Django and i dont know much} -

Getting all of foreign key's fields
I have 3 models. One model is the User model, another is a Post model, and the other is a notifications model. I want to use Django's REST framework to show all of the notifications for the signed in user, plus each user that interacted with the signed in user. class Notification(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='actors') actor = models.ForeignKey(User, on_delete=models.CASCADE, related_name='users') post = models.ForeignKey(Post, on_delete=models.CASCADE, blank=True, null=True) type = models.ForeignKey(NotifType, on_delete=models.CASCADE) is_read = models.BooleanField() created_at = models.DateTimeField(auto_now_add=True) class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) status = models.CharField(max_length=200) share_count = models.IntegerField(default=0) created_at = models.DateTimeField(auto_now_add=True) url = models.CharField(max_length=150) serializers.py class NotificationSerializer(serializers.ModelSerializer): class Meta: model = User fields = '__all__' views.py class GetNotifications(ListAPIView): serializer_class = NotificationSerializer def get_queryset(self): user = get_object_or_404(User, id=self.request.user.id) return User.objects.select_related().filter(users__user=user).order_by("-users__created_at") What I have currently returns all users who have interacted with the signed in user. However, it doesn't return the details about the notification. I want all details about each notification, including the details about the post. So the output should be something like this: { "post": { "id": 1, "status": "Hello!", . . . }, "user": { "username": "Ben", "avatar": "example.png" . . }, is_read: 1, created_at: 2017-07-21, type: 2 }
