Django rest framework view patching for unit test
here is my view that I want to test: class CityWeather(APIView): def get(self, request): city = request.GET.get('city', None) if city: city_weather = get_weather_data(city) if city_weather: return Response(city_weather, status=status.HTTP_200_OK) return Response({"error": "City was not found"}, status=status.HTTP_404_NOT_FOUND) so far here is my tests.py: class TestWeatherAPI(TestCase): def test_get_weather_data(self): with mock.patch('weather.utils.get_weather_data') as mock_get: response_data = { "current_temperature": "3.1°C", "current_pressure": 1033, "current_humidity": 86 } mock_get.get_weather_data.return_value = response_data response = self.client.get(reverse('get_city_weather'), {'city': 'London'}) self.assertEqual(response.status_code, 200) self.assertEqual(response.json(), response_data) As we can see, I want to patch only the get_weather_data in the view. How can I do this ? -

Python [Errno5] Input/output error when converting audio file
I wrote a video/audio converter using Python PyTube. The code for converting videos is working but the audio isnt. Im using moviepy to write the audiofile because it isnt possible with pytube alone. But now I have a error which I dont have normally. If I'm logged in into putty everything works but if I close the console this error appears: [Errno 5] Input/output error I googled it and it says that if the console can't print out messages (because putty is closed) this error appears. I just need the cause in my code for it. This is my code for the mp3 converting: if format == "3": yt = YouTube(videolink) downloads = MEDIA_ROOT + "/videos/" audio_file = yt.streams.filter(only_audio=True).first().download(downloads) base, ext = os.path.splitext(audio_file) clip = AudioFileClip(audio_file) clip.write_audiofile(base + uuid + ".mp3") clip.close() audioclip = clip.audio basename = os.path.basename(base + uuid + '.mp3') os.remove(base + '.mp4') new_video = Video( path = basename, link = videolink ) request.session['file'] = basename new_video.save() Ignore the database stuff with "new_video" this is just for my framework for database interaction. The important lines are this: clip = AudioFileClip(audio_file) clip.write_audiofile(base + uuid + ".mp3") clip.close() -
Django + Celery: How to run a task after subtasks from different scheduled Tasks are finished
I'm currently building a webapp with Django and Celery. I have one task (sometask) that adds an unknown number of other tasks(othertask) in a for loop to the queue. Now I don't understand how I can run another Task(task3) after sometask with all the subtasks are done. I understand that you can chain tasks for example, but if I chain othertask to sometask it will run before the subtasks are done. Could someone please give me some input on how to get it done the way I described? Example of my tasks.py @shared_task(bind = True) def sometask(self): for whatever: othertask.delay() return "done" @shared_task(bind = True) def othertask(self): pass @shared_task(bind = True) def task3(self): pass Celery.py: app.conf.beat_schedule = { 'weekly':{ 'task': 'webapp.tasks.sometask', 'schedule': crontab(minute=0, hour=23, day_of_week='sat'), } } -

How do I auto create pages for each element with Wagtail?
I'm learning Wagtail, and I'm struggling to understand auto page creation. Say I have a website where users can fill a form to become a "fan". I have a page where all the fan names are listed, e.g. fanlist = Fan.objects.order_by( "-timestamp") When a user submits the form and becomes a fan, they are added to the page with the fan list. Now I want to be able to create a page for each fan, so that the names in the fan list page link to a page for that specific fan. How can I do this programmatically and dynamically, so that each time a new fan signs up, the websites auto creates a page for this fan? -

Online pricing/ordering web with django: display/show a button aftern form submitted

How to show a django form for many to many with through field?
I have created 3 model: class PropertyExtra(models.Model): type = models.CharField(choices=ExtrasType.choices, max_length=7) property_type = models.IntegerField(choices=PropertyType.choices) title = models.CharField(max_length=100) identifier = models.CharField(max_length=20, unique=True) class Property(models.Model): extras = models.ManyToManyField(PropertyExtra, through="PropertyExtraData") class PropertyExtraData(models.Model): value = models.CharField(blank=True, null=False, max_length=300) property_extra = models.ForeignKey(PropertyExtra, on_delete=models.CASCADE) property = models.ForeignKey(Property, on_delete=models.CASCADE) In PropertyExtra an admin user can add items like Electricity, Gas, Central Heating, etc. Some values will be boolean and some int which depends on the ExtrasType enum in the PropertyExtra. The specific value per property will be saved within the PropertyExtraData.value. Currently I'm have a form wizard to create a new Property using django-formtools and I'd like one of the steps to include a form that shows all the available PropertyExtras for a specific property_type. Basically if I have the above mentioned Electricity, Gas, Central Heating records in PropertyExtra - for a specific property_type I want to render 3 checkboxes where the user can mark them. Preferably would like to use ModelForm or ModelFormSet in order to simplify editing and saving but it's not possible - I'm looking for suggestions or 3rd party packages. -

Django Rest Framework - Doesn't appear to be paginating queryset correctly causing a long wait time before displaying on front end
I am experiencing an issue where it is taking upwards of 30 seconds to receive 25 items in a paginated response. This happens on original load of the page as well as any subsequent page requests via the datatables previous and next buttons. The model in question has roughly 600k records in it with the request to the api providing a query parameter to filter this by listing type (Letting or Sale). There are other filters applied to the queryset to ignore items that don't fall into the queue leaving 37k records on the Sales side and 90k on lettings that are returned. My model structue is as follows: class Listing(models.Model): date_added = models.DateField(verbose_name='Date Added', auto_now_add=True, auto_now=False) listing_id = models.CharField(max_length=15, blank=False, primary_key=True) portal = models.CharField(max_length=30, blank=False) url = models.URLField(max_length=200, blank=False) date = models.DateField(verbose_name='Listing Date', auto_now_add=False, auto_now=False, null=True, blank=True) listing_status = models.CharField(max_length=30, blank=False) outcode = models.ForeignKey( 'postcode_data.Outcode', blank=True, null=True, default=None, on_delete=models.CASCADE, related_name='+') sector = models.ForeignKey( 'postcode_data.Sector', blank=True, null=True, default=None, on_delete=models.CASCADE, related_name='+') address = models.CharField(max_length=200, blank=False) postcode = models.CharField(max_length=15, blank=False) description = models.TextField(blank=True) price = models.DecimalField(max_digits=9, decimal_places=1, default=Decimal(0.0)) property_type = models.CharField(max_length=30, blank=False) beds = models.PositiveIntegerField(default=0) baths = models.PositiveIntegerField(default=0) agent = models.CharField(max_length=150, blank=False) agent_company = models.CharField(max_length=100, blank=False) agent_branch = models.CharField(max_length=50, blank=False) available = … -

Using Django template tags and filters in javascript
I am building a search engine using Algolia in a client's Django project. In the html section of the template the client uses this line to format the date correctly. <span><em>posted</em> <strong>{{ dealer_announcement.publish_date|date:"F jS, Y" }}</strong></span> In the script on the template I define what each hit on the search engine should look like in a template like so. {% verbatim %} const hitTemplate = '' + '<span><em>posted</em> <strong>{{ publish_date }}</strong></span>' + '</div>' + ''; {% endverbatim %} This works fine, however the date is not formatted correctly so I tried to match the same format like so. {% verbatim %} const hitTemplate = '' + '<span><em>posted</em> <strong>{{ publish_date|date:"F jS, Y" }}</strong></span>' + '</div>' + ''; {% endverbatim %} but then nothing shows up. How can I use the same filters and tags within the script to have it match the original output.
