I want to join and format values and array of objects to a string in python. Is there any way for me to do that? url = "https://google.com", search = "thai food", search_res = [ { "restaurant": "Siam Palace", "rating": "4.5" }, { "restaurant": "Bangkok Palace", "rating": "3.5" } ] url = "https://google.com", search = "indian food", search_res = [ { "restaurant": "Taj Palace", "rating": "2.5" }, { "restaurant": "Chennai Express", "rating": "5.0" } ] url = "https://bing.com", search = "thai food", search_res = [ { "restaurant": "Siam Palace", "rating": "1.5" }, { "restaurant": "Bangkok Palace", "rating": "4.5" } ] url = "https://bing.com", search = "indian food", search_res = [ { "restaurant": "Taj Palace", "rating": "4.5" }, { "restaurant": "Chennai Express", "rating": "3.0" } ] I want to be able to format the values as such: If I could make it look like: all_data = [{ url = "https://google.com", results = [{ search = "thai food", search_res = [{ "restaurant": "Siam Palace", "rating": "4.5" }, { "restaurant": "Bangkok Palace", "rating": "3.5" }] }, { search = "Indian food", search_res = [{ "restaurant": "Taj Palace", "rating": "2.5" }, { "restaurant": "CHennai Express", "rating": "5.0" }] }] }, { url = "https://bing.com", … -

How to initialize form with some parameters of model instance
I would like be able to send SMS/Email notifications manually using the groups/users of a model instance. Let's say the model looks like this: class Memo(models.Model): title = models.CharField(max_length=100) receiver = models.ManyToManyField(EmployeeType, related_name='memos_receiver') I pass the object instance to the view: path('<int:pk>/notify', NotificationView.as_view(), name='memos-notify'), The form and the view are where I am having trouble. I figure I should be able to just pass the forms initial fields right there in the view: class NotificationView(FormView): template_name = 'memos/notification_form.html' form_class = MemoNotificationForm success_url = reverse_lazy('overview') def get_initial(self): initial = super(NotificationView, self).get_initial() memo = Memo.objects.filter(id=id) initial['receiving_groups'] = memo.receiver return initial And the form looks like this: class MemoNotificationForm(forms.Form): class Meta: fields = [ 'receiving_groups' ] receiving_groups = forms.MultipleChoiceField( required=False, widget=forms.CheckboxSelectMultiple) TypeError: int() argument must be a string, a bytes-like object or a number, not 'builtin_function_or_method' Do I need to initialize the queryset in the form? Would appreciate it if someone could paint me a clear picture of the why and how here. Thank you! -

Django TestCase object has no attribute 'login'
I have used selenium to test my login method and it works fine. Then, I tried to test other parts of the website. So, I needed to create a user in my test. To do that, I've used client instead of request factory (since there are middleware classes).

get_decoded method show "Session data corrupted" in Django session
I have an application which using Django 2.0 and I'm facing with an issue about session data today.

I really want to read the session from the backend using manage.py shell and those script above. -
How to return user session id alongside Django rest serializer output
I'm writing a web application with Django. In one of my APIs which is using Django rest_framework, I want to return user's session ID alongside the default response.

How can I convert a duration or a string to an integer in a queryset in Django views.py?
I need to calculate the time difference between two rows. This duration then needs to be adjusted up to 1 if the total is 0, or if the total is over 15 minutes, adjusted to 0--I was going to put this corrected amount in strtime. Unfortunately, my calculated times are not correct nor can I convert the extracted minutes to an integer in order to test if the duration is > 15 or < 1. The only reason I converted to a string was to see if I could then convert to an integer--it didn't work. I also tried to convert to a pandas dataframe in order to do the calculations, but I could not get it back into some format to display properly on the html page. How can I do an accurate calculation between rows and how can I adjust from 0 to 1 or > 15 to 0? I have tried many different versions--just not having much luck. I normally work in javascript--this is my first Django project. I have sanitized and shortened the data. This page will fit into an existing Django setup. Thank you in advance! Code is below. models.py class testmodels(models.Model): primary_key_id = models.CharField(max_length=150, … -
Django queryset caching with exists()
Let's say, I'm trying to change the name of all profiles whose name is John to Mike queryset = Profile.objects.filter(name='John') Method 1: if queryset: queryset.update(name='Mike') Method 2: if queryset.exists(): queryset.update(name='Mike') QUESTION: Which method is more efficient? Usually, I use exists() in the same line as my filter, so it queries once. However, I'm not sure if Method 2 will make another query to the database, making it less efficient. -
Using Django to display images
I am attempting to use Django to display 3 random images from a large list of user submitted images. Each image has other values associated with it like the author, so I've been making each image a model with the image field holding the image itself. Unfortunately, I can't figure out how to randomly pick from that list and pass it in to the .html page to display it correctly. So far, I've been able to get user submitted pictures to be saved as models and submitted to a folder /media/images/. My views.py will grab 3 random and unique pictures from that folder like so: def home_view(request): form = MForm(request.POST or None) if form.is_valid(): form.save() message_list = MModel.objects.all() #Get first random file file1choice = random.choice(os.listdir(DIR)) #Get second random file file2choice = random.choice(os.listdir(DIR)) while(file2choice == file1choice): file2choice = random.choice(os.listdir(DIR)) #Get third random file file3choice = random.choice(os.listdir(DIR)) while(file3choice == file1choice or file3choice == file2choice): file3choice = random.choice(os.listdir(DIR)) context = { 'file1': file1choice, 'file2': file2choice, 'file3': file3choice, } return render(request, "home.html", context) In my .html file that the user sees, I access each image passed like so: <img src="/media/images/{{ file1 }}" width="300" height="180" alt=""> Unfortunately, this doesn't allow me to actually access the … -
Why does django send_mail fails to send email with no errors?
I want to use send_mail in django, however it doesn't send any email. Here is my settings.py: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'MY-GMAIL-USERNAME@gmail.com' EMAIL_HOST_PASSWORD = 'MY-GMAIL-PASSWORD' EMAIL_PORT = 465 EMAIL_USE_TLS = False EMAIL_USE_SSL = True DEFAULT_FROM_EMAIL = EMAIL_HOST_USER SERVER_EMAIL = DEFAULT_FROM_EMAIL Then, I run python manage.py shell: from django.conf import settings from django.core.mail import send_mail subject = 'Test Subject' message = 'Test Message' email_from = settings.EMAIL_HOST_USER recipient_list = ['MY-YAHOO-USERNAME@yahoo.com'] send_mail(subject, message, email_from, recipient_list) It doesn't send the email and it prints: Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: Test Subject From: MY-GMAIL-USERNAME@gmail.com To: MY-YAHOO-USERNAME@yahoo.com Date: Mon, 09 Dec 2019 21:02:16 -0000 Message-ID: <157592533640.18842.5494330274157836181@thinkpad-e560> ------------------------------------------------------------------------------- 1 Test Message which seems to have no errors. Why doesn't it send the email? What is wrong? Why doesn't it log any errors?

I'm confused. What did I do wrong? -
Why can't I PATCH Django REST Framework PrimaryKeyRelatedField to empty list?
I'm running into a weird issue in Django REST Framework. I'm attempting to add & remove groups to/from users using PATCH requests. I am able to PATCH to /api/users/:id/ to update the groups list, which is initially empty. For example, the following actions yield these results: PATCH /api/users/:id/ {"groups": [1]} -> Results in user with groups: [1] PATCH /api/users/:id/ {"groups": [1, 2]} -> Results in user with groups: [1,2] PATCH /api/users/:id/ {"groups": [1]} -> Results in user back to groups: [1] So I am successfully updating the state with PATCH requests. However the following fails to update accordingly: PATCH /api/users/:id/ {"groups": []} -> Results in user still at groups: [1] Here is my UserSerializer class: class UserSerializer(serializers.ModelSerializer): groups = serializers.PrimaryKeyRelatedField(many=True, queryset=Group.objects.all(), allow_empty=True, required=False) class Meta: model = User fields = ( 'id', 'username', 'first_name', 'last_name', 'is_staff', 'is_authenticated', 'is_superuser', 'email', 'groups' ) My suspicion is that it has something to do with PrimaryKeyRelatedField - I have tried many combinations of arguments to the constructor to no avail. -

My goal is essentially to to insert y into Avg Rating {{ }} Is there a way similar to content.review_set.count? Or is it best to do in views? -

TemplateSyntaxError: Could not parse the remainder: '()' from 'size.toLowerCase()'

I am using this sample tutorial as is. .html {% load static %} <!DOCTYPE html> <html lang="en" > <head> <meta charset="UTF-8"> <title>Option Groups</title> <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700,400italic"><link rel='stylesheet' href='https://gitcdn.xyz/cdn/angular/bower-material/v1.1.20/angular-material.css'> <link rel='stylesheet' href='https://material.angularjs.org/1.1.20/docs.css'><link rel="stylesheet" href="./style.css"> </head> <body> <!-- partial:index.partial.html --> <div ng-controller="SelectOptGroupController" class="md-padding selectdemoOptionGroups" ng-cloak="" ng-app="MyApp"> <div> <h1 class="md-title">Pick your pizza below</h1> <div layout="row"> <md-input-container style="margin-right: 10px;"> <label>Size</label> <md-select ng-model="size"> <md-option ng-repeat="size in sizes" value="{{size}}">{{size}}</md-option> </md-select> </md-input-container> <md-input-container> <label>Topping</label> <md-select ng-model="selectedToppings" multiple=""> <md-optgroup label="Meats"> <md-option ng-value="topping.name" ng-repeat="topping in toppings | filter: {category: 'meat' }">{{topping.name}}</md-option> </md-optgroup> <md-optgroup label="Veggies"> <md-option ng-value="topping.name" ng-repeat="topping in toppings | filter: {category: 'veg' }">{{topping.name}}</md-option> </md-optgroup> </md-select> </md-input-container> </div> <p ng-if="selectedToppings">You ordered a {{size}} pizza with {{printSelectedToppings}}.</p> </div> </div> <!-- Copyright 2018 Google LLC.
