Why my website called an API 2 times at a time
Here is my project: http://18.217.194.30/ Why it's using two requests at the time ? ) 49 / 60 REQUESTS LEFT) 60 requests for 1 IP or for all daily users ? This is my views.py: def user(req, username): username = str.lower(username) # Get User Info with urlopen(f'https://api.github.com/users/{username}') as response: source = response.read() data = json.loads(source) # Get Limit Call API with urlopen(f'https://api.github.com/rate_limit') as response: source = response.read() limit_data = json.loads(source) context = { 'username': username, 'data': data, 'limit_data': limit_data, } return render(req, 'user.html', context) Here is my project github: https://github.com/nathannewyen/octoProfile-github/blob/master/octoProfile_app/views.py -
Confused with static files in django production?
I have this structure in my django project: The structure of the folders is as below image: I have these line in settings.py: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) INSTALLED_APPS = [ ... 'django.contrib.staticfiles', ... ]**strong text** MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'), ] and I have this in the urls file: if settings.DEBUG: # new urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) if DEBUG = True: I hit python manage.py runserver and then 127.0.0.1:8000 and everything is good. if DEBUG = False: I hit python manage.py collectstatic The static files get collected in the staticfiles directory. I then hit python manage.py runserver and then 127.0.0.1:8000 The static files and media files are not loaded in this case. Any solution to this problem? -

How to destroy resource in a django+fastcgi+IIS setup?
I have this interesting issue. I am using the Django setup to serve queries. Initially, I was hoping for concurrent execution but there is one component X that doesn't allow its multiple invocation due to apparent failure in its license checking code when called parallely. To make sure that only 1 instance of django runs, I am planning to do the following: IIS: It doesn't have anything to do with concurrency directly as far as I checked. I might be wrong. FastCGI module in IIS: Max instances: 1 ( I think this means that fastcgi will only load 1 codebase of django app in memory.) Instance Max Request: 200 (This will make sure that after my above codebase of django app in memory handles 200 requests sequentially, it destroys itself and restart.) Why this recycling is even necessary? Queue Length: 1000 (This will create a backlog of incoming requests and even if they are coming from multiple sources, it will make sure that they aren't rejected immediately) Django: Now this component X takes around 1-2 second to load itself, so i can't put its loading code inside POST view function. I am planning to put it in apps.py inside a … -
Reverse for url not found in python urlpatterns
I made URL config urlpatterns = [ path('', lambda request: redirect('stocks', permanent=False)), path('stocks', views.stocks.index, name='stocks.index'), path('stocks/<slug:slug>', views.stocks.show, name='stocks.show'), path('stocks/<slug:slug>/load', views.stocks.load, name='stocks.load') ] These URLs are ok, and they work but not first path('', lambda request: redirect('stocks', permanent=False)), It gives when I try http://127.0.0.1:8000 NoReverseMatch at / Reverse for 'stocks' not found. 'stocks' is not a valid view function or pattern name. But if I try http://127.0.0.1:8000/stocks all is ok What's wrong here? -
how can i access to the intermediary table fields through the parent table in django?
this is my tables: class MyUser(models.Model): pass class Product(models.Model): name = models.CharField() class Order(models.Model): customer = models.ForeignKey(MyUser, on_delete=models.CASCADE) products = models.ManyToManyField(Product , through='MidCartProduct') class MidCartProduct(models.Model): class Meta : unique_together = (('order_id' , 'product_id')) order_id = models.ForeignKey(Order , on_delete=models.CASCADE) product_id = models.ForeignKey(Product , on_delete=models.CASCADE) quantity = models.PositiveSmallIntegerField() and so how can i access to the intermediary table quantity field through the Order table? is that possible? i tried to do this but not working : >>> a = Order.objects.first().products.first() >>> a.quantity Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: 'Order' object has no attribute 'quantity' Sorry for my bad English -
Django - how to call a phone number AND open a form page with one click?
I hope to get ist straight: I have a Django app with customer addresses and 'activities' whoch protocolls any contact to customers via email or phone. When the user clicks on a phone number (link) I want the system to dial that number and at the same time to create a record in a table (activities), render another page with a form, where he writes down notes while talking to the customer. How can I do that without a second click? I know, I create a link <a href='tel:{{ customer.phone }}'> that much is clear. But how to do a second action on the same click? Probably with JavaScript (I use jQuery, but am a novice to JavaScript). Alternatively I thought I could call the "Call-Phone-Number" action in a view which is called by the link (instead of 'tel:...') in the first place and does all the form rendering, which is more comfortable for me. But how to call a phone number from a view in python and render a page simultaniously (or one after the other without waiting) ? I hope my situatuon is clear... Thanx for any help! -
How to make Serializer class for manytomany field to be empty on POST
The ItemSerializers is for the Model Item which is a manytomany field in the model supplier , am trying to make it not required , but it is not working ,, her is my code : class SupplierSerializer(serializers.HyperlinkedModelSerializer): id = serializers.IntegerField(read_only=True) person_name = serializers.CharField(max_length=120, allow_blank=True) company_name = serializers.CharField(max_length=120, allow_blank=True) tax_number = serializers.CharField(max_length=120, allow_blank=True) items = ItemSerializer(many=True, allow_null=True, required=False) class Meta: model = Supplier fields = '__all__' the problem is in the line items = ItemSerializer(many=True, allow_null=True, required=False) AS I can't send a post a request with items field empty !! -
Do I need to create the template if I want to load the template correctly?
def directory_index(path, fullpath): try: t = loader.select_template([ 'static/directory_index.html', 'static/directory_index', ]) except TemplateDoesNotExist: t = Engine(libraries={'i18n': 'django.templatetags.i18n'}).from_string(DEFAULT_DIRECTORY_INDEX_TEMPLATE) c = Context() else: c = {} files = [] for f in fullpath.iterdir(): if not f.name.startswith('.'): url = str(f.relative_to(fullpath)) if f.is_dir(): url += '/' files.append(url) c.update({ 'directory': path + '/', 'file_list': files, }) return HttpResponse(t.render(c)) This snippet is from static.py source code. It seems select_template will try to load directory_index.html or directory_index from the static subdirectory. To avoid raising the error, I guess I need to create a static folder following my DIR path and place directory_index.html in it, right? -
Django way of model reverse_name with different linked model classes
I have a Problem with accessing models of different classeds via related_name and I need your help to find a clean solution, that uses few SQL queries and is easily extendable: class RoundTripToDifferentPlaces(models.Model): price = models.FloatField(default=0) user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE) ... class PlaceVisit(models.Model): roundtrip = models.OneToOneField(RoundTripToDifferentPlaces, related_name="place_visit") individual_price = models.FloatField(default=0) name = models.CharField(max_length=31, null=True) street = models.CharField(max_length=31, null=True) creation_date = models.DateTimeField(auto_now_add=True) ... class RestaurantVisit(models.Model): place = models.OneToOneField(Job, on_delete=models.CASCADE, primary_key=True) Some more fields...about pricedetails class LibraryVisit(models.Model): place = models.OneToOneField(Job, on_delete=models.CASCADE, primary_key=True) Some more fields...about pricedetails ...many more subcategories of places and i will add more in the future In my views I loop through the RoundTripToDifferentPlaces and i need to grab all information of the related models.

Running 10 functions asynchronously in Djano Views using Asyncio
Im facing difficulties while trying to execute around 10 functions simultaneously using asyncio in Django. I could not find nay clear documentation on how to use asyncio with django. I made around 10 http requests to different using TOR which is by default slow. Instead of making these requests one by one, which usually takes around 2 minutes, I wanted to perform all the 10 requests simultaneously. There are 10 distinct functions each making a http request a different URL and scrape data and return JSON. URLscrape.py : async def scrape1(username): response = request.get('http://example.com'+username) return response.json() async def scrape2(username): response = request.get('http://something.com'+username) return response.json() I have 10 individual functions like the above with different URLs and perfrom scraping and return a json data. In Django views, I did like this: Views.py from URLscrape import scrape1, scrape2........scrape10 def scrapper(): loop = asyncio.get_event_loop() feature1 = loop.run_in_executor(None, scrape1, username) feature2 = loop.run_in_executor(None, scrape2, username) .... feature10 = loop.run_in_executor(None, scrape10, username) response1 = await future1 response2 = await future2 ..... response10 = await future10 response1 = response1.text ...... response10 = response2.text return render(request, 'index.html', {'scrape1':response1,'scrape10':response10}) But I dont know how to use loop.run_until_complete() to complete the script.

Charting over 5 million measurements of sensor with Django
i'm currently using Echarts (i've used in the past Highcharts) and it's working fine with small datasets: it has a lot of features, options and it's pretty nice to view and use. Now, i have a lot of sensors that acquires a lot of data (data is captured with a frequency of 500khz) and the users needs to analyze the acquired dataset (that has 2/5 millions of point) many times a day/week. I've seen that those charting libraries are totally a crap solution when the dataset is very big, so, any solution? I wish to integrate those charts with my django app, so an integrated solution (or a python based one) is mandatory... -
Django + DjangoRestFramework: How to build a Django WebApp using DjangoRestFramework API?
I know Django Web App Development, API Development with DjangoRestFramework, and using DjangoRestFramework API in other programming platforms such as JavaScript and React. But what I am having confusion is at using the DjangoRestFramework API in a simple Django Web Application. How to retrieve the values that have been parsed from a serializer of DjangorestFramework API and return it to the view, which is an HTML template? The URL api/task-list returns all tasks added in the database. This is how it is done in API programming. def taskList(request): tasks = Task.objects.all() serializer = TaskSerializer(tasks, many=True) return Response(serializer.data) While in the Django web app the tasks are passed as a context and it returns or renders a template where we can loop the task from the tasklist and display it in an HTML view page. def taskList(request): tasks = Task.objects.all() context = {'task': tasks} return render(request, 'todo/tasklist.html', context) If we have to use the API in Javascript based application than we can do it simply by doing the following: If there is a HTML division with id list-wrapper <div id="list-wrapper"> Than in the JavaScript section we can consume the API and do the data retrieval operation like shown below: buildList() function … -

How to freeze datetime.now for unit testing
