Get Display CHOICE in a ForeignKey Django Model
My models: class Sell(models.Model): item = models.OneToOneField(Buy, related_name='sell', on_delete=models.CASCADE) date = models.DateField(default=timezone.now) code = models.ForeignKey(Order, related_name='order', on_delete=models.CASCADE, null=True, blank=True) class Order(models.Model): status_choice = ( ("W", "Aguardando aprovação do pagamento"), ("A", "Pagamento aprovado - produto em separação"), ) code = models.CharField(max_length=100) status = models.CharField(max_length=1, choices=status_choice, default='W') My template: {% for order in orders %} <tr> <td>{{ order.code__code }}</td> <td>{{ order.date }}</td> <td>{{ order.get_code__status_display }}</td> </tr> {% endfor %} The output I was expecting: "Aguardando aprovação do pagamento" but it's not printing this. Any help to display the full text instead the only word "W"? Thank you! -
Django unit tests - API calls slowing down testing greatly, optimize or rewrite?
I have an application that calls to OpenWeatherMap API and I decided to write a test for the purpose of verifying that the cities are listed on the url page context. I used the setUpTestData class method to populate the test DB, but when I run the tests the time taken goes from 0.0XX seconds without the test DB to like 5.7XX seconds with the test DB. I believe its the API calls to populate the DB that is causing the slow down (Which I assume also counts against my limit for calls per hour on the API key) and I am wondering what the proper way would be to test something like this? I.E something that relies on API data to work properly. Do I need to optimize my code, or is my approach wrong? I am relatively new to unit testing, so I appreciate any tips or advice you may have. views.py class WeatherHomeView(TemplateView): template_name='weather/home.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) url = 'API URL' cities = City.objects.all() weather_data = [] for city in cities: city_weather = requests.get(url.format(city)).json() weather = { 'city' : city, 'temperature' : city_weather['main']['temp'], 'description' : city_weather['weather'][0]['description'], 'icon' : city_weather['weather'][0]['icon'], } weather_data.append(weather) context = {'weather_data' … -
Mocking dataframe for testing in python
I am trying to mock a dataframe for unit testing in python. here is the form of the table: However, I am having trouble hard coding a dataframe to have a json within it. This is my attempt at mocking a record: test_strip = pd.DataFrame( [[1], "2020-09-21", [{'WTI': {'1604188800000': '40.25', '1606780800000': '40.51', '1609459200000': '40.81', '1612137600000': '41.13', '1614556800000': '41.45', '1617235200000': '41.74', '1619827200000': '42.00', '1622505600000': '42.22'} }], [1]], columns=['id','trade_date','prices','contract'] ) This yields the following error: ValueError: 4 columns passed, passed data had 10 columns So it appears it is interpreting my json as separate records. Appreciate any help anyone might have. -
Is there any other way to avoid duplicate data while scraping and avoid storing the same data in database?
I have a simple model. models.py class Content(models.Model): title = models.CharField(max_length = 300, unique = True) category = models.CharField(max_length = 50) def __str__(self): return self.title then I'm scrapping the data from some sources and want to store in this table. toi_r = requests.get("some source") toi_soup = BeautifulSoup(toi_r.content, 'html5lib') toi_headings = toi_soup.findAll("h2", {"class": "entry-title format-icon"})[0:9] toi_category = toi_soup.findAll("a", {"class": ""})[0:9] toi_news = [th.text for th in toi_headings] toi_cat = [tr.text for tr in toi_category] for th in toi_headings: toi_news.append(th.text) for tr in toi_category: toi_cat.append(tr.text) for title, category in zip(toi_news, toi_cat): n = Content.objects.create(title=title, category=category) So here, error is UNIQUE Constraint failed. So, If I remove the UNIQUE Constraint, then everything works but mulitple copies of data are stored as the page refreshes. Is there any other way to work with this? -
Can't login with new users, only old users (Django Rest Framework views.obtain_auth_token)
I first noticed this after I deployed my site, but I checked when running it locally and I get the same issue, so I guess this was happening before deployment without me noticing. Posting log in credentials for new users to obtain a token using DRF views.obtain_auth_token only works for users that I created early in the project, not new ones (trying to login with new users returns a bad request cant login in with user credentials). I don't understand why because new users are still created, and appear in the admin User panel along with the old users, and I can see tokens are still generated for new users created. I'm guessing it might be because I've done something wrong when changing the user model, but I'm fairly sure I created the first users after I changed it, so I'm not really sure. Here is my user model: class UserManager(BaseUserManager): use_in_migrations = True def _create_user(self, email, password, **extra_fields): '''Create and save a user with the given email, and password. ''' if not email: raise ValueError('The given email must be set') email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, password=None, **extra_fields): extra_fields.setdefault('is_staff', False) extra_fields.setdefault('is_superuser', … -

VS Code | Django model error (doesn't recognize inheritance)
I have a model, "Post," and I'm calling it in views.py like this: def index(request): context = { 'posts': Post.objects.all() } return render(request, 'feed/index.html', context This was done, following this tutorial. It works just fine on the website itself, but VS Code is giving me an error stating, "Class 'Post' has no 'objects' member" from Pylint. But, where it's a Django model that was correctly setup in models.py; everything is working properly on the server.

Django forms initial value of ChoiceField when choices are dynamically set in __init__()
I have a Django form class: class FilterForm(forms.Form): number = forms.ChoiceField() def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # ... (logic for setting up available options) self.fields['number'].choices = number_choices When I instantiate this form with data={'number': -1} (and assuming that is a valid option's value), the form loads in the page with the last option in the select dropdown selected. I've attempted to set self.fields['number'].initial = kwargs['data']['number'], and I've tried self.initial['number'] = kwargs['data']['number'], both after the call to super(), and neither has worked to set the correct initially selected value in the dropdown. What am I missing here? -

Django Admin - Cannot change <h2> color
I am learning Django. I am customizing the Django Admin page. I have created a base_site.html file in my templates to overwrite the default admin html. Additionally, I have created a stylesheet that I've tied to it. Here's my problem: By default, there is a div on the right side of the content with an h2 header that states "Recent Actions." I want to change this texts color, but my CSS won't seem to work on these words... <div id="content-related"> <div class="module" id="recent-actions-module"> <h2>Recent actions</h2> <h3>My actions</h3> <p>None available</p> </div> </div> I have tried each of the following CSS: #content-related{ color: blue; } .module h2{ color: blue; } #recent-actions-module h2{ color: blue; } #content related h2{ color: blue; } Nothing works... Am I missing something?
