How to handle multiple variables for the same parameter name (for checkbox)?
I'm writing a code for quiz app, which is having multiple choice for each question.According to my requirement one question may contains multiple correct answer. i'm able to check for single answer if its radio button rather than checkbox. But i need checkbox instead of radio. So i given checkbox for multiple selection. i used request.POST.getlist('choice') which returns only the order of selection. I can't able to check it with my model whether its correct answer or not. views.py def checkanswer(request, question_id): question = TestQuestion.objects.get(pk=question_id) #for single answer checking(if its radio button) i used the following #selected_choice = question.testchoice_set.get(pk=request.POST.get('choice')) a = request.POST.getlist('choice') #print(selected_choice.is_answer) #if selected_choice.is_answer == 'Yes': #return HttpResponse('Right') return HttpResponse('Wrong') test.html <form action="{% url 'polls:checkanswer' question.id %}" method="post"> {% csrf_token %} {% for choice in question.testchoice_set.all %} <input type="checkbox" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" /> <label for="choice{{ forloop.counter }}">{{ choice.choice_opt }}</label><br /> {% endfor %} <input type="submit" value="Vote" /> </form> I expect, each option chooses by the user need to be checked with data base whether its right or not. -

I have an UpdateView where the user can update/create their profile details. The details include the profile picture, bio, and gender. I want to be able to take the user's uploaded profile image, crop it, and then save it. However, in my current implementation it only saves the image to a path I specify and that's it.

Why my custom.css file isn't modifying my materialize.css?
I wanted to modify the grid system, add some borders to rows, columns etc. I know, that I should create separate folder (in my case it's custom.css) and write it there, but it looks like my site sees this file, but doesn't see changes in there. I tried this in my custom.css .row-custom { border: 5px solid #42a5f5; } and just add row-custom to row class Like this <div class="row row-custom"> <div class="col s12 ">This div is 12-columns wide on all screen sizes</div> <div class="col s6 ">6-columns (one-half)</div> <div class="col s6">6-columns (one-half)</div> </div> If I add .row-custom into my header in layout.html it works properly. Here's my custom.css file: https://imgur.com/sNy6z9G and here's my custom.css view in sources from the website: https://imgur.com/zXKiHxG (these css I also had to put into header because otherwise it wasn't working, I deleted it earlier) My header: https://imgur.com/fAI72el Also, my materialize.min.css works correctly.

Weird POST request posting csrf_token as password

Properly serialize a value so it is passed to CurrentUserField() properly
I started using Django REST this week, and I am running into something I do not understand. I building a POST that takes in the following payload: { "requestor":"naughtron", "test_name":"testName", "workers":"2" } The value for requestor in our data model is set to CurrentUserField() When the payload comes into the serializer class TestSuiteRequestSerializer(serializers.Serializer): requestor = what_do_use_here? test_name = serializers.CharField(required=True, allow_blank=False, max_length=100) workers = serializers.CharField(required=True, allow_blank=True, max_length=3) the following error is thrown database_1 | ERROR: null value in column "requestor" violates not-null constraint because I am believe it is not being serialized properly therefore the model has no idea what to do. I looked through the documentation and the current list of Serializer fields. Nothing seems to be helping. -
Django: Listing all permissions specific to a model, and listing them in a table
I'm having trouble listing all model-specific permissions in a table. I'm able to pull out permissions through {{ perms.account }} in the html, but it won't filter for permissions specific to the account model. Futhermore i want to list each permission in a html table, with the permissions description, and a checkmark if its granted: Permission1 Desc1 V <!-- Granted --> Permission2 Desc2 X <!-- Not granted --> I have tried for-looping all permissions, and filtering out the ones related to the model account, and then for looping to get the different rows in the table. This, however, just returned a long string of all permissions names. I have also tried the code bellow, but was not able to retrieve data in the html template through {{ permissions }}, {{ account.permissions }} or {{ permissions.account }} class cms_users_user_permissions(generic.DetailView): model = Account template_name = 'cms/users/cms-users-user-permissions.html' content_type = ContentType.objects.get_for_model(Account) permissions = Permission.objects.filter(content_type=content_type) views.py class cms_users_user_permissions(generic.DetailView): model = Account template_name = 'cms/users/cms-users-user-permissions.html' models.py class Account(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) site = models.CharField(max_length=50, choices=(('all', 'all'), ('danielk', 'danielk')), blank=True) role = models.CharField(max_length=50, choices=(('Administrator', 'Administrator'), ('Moderator', 'Moderator'), ('Editor', 'Editor'))) phone_number = models.CharField(max_length=8) birth_date = models.DateField() street_adress = models.CharField(max_length=255) note = models.TextField(blank=True); zip_code = models.CharField(max_length=4) city = … -
Django Model Many-to-Many and Bridge Tables
I'm trying to understand how to properly setup my models in order to have a many-to-many relationship, I noticed that there is a ManyToManyField option while creating models but I can't seem to understand the logic of it and how to properly make it work. I'd like to share my code and explain along the way. from django.db import models class Major(models.Model): name = models.CharField(max_length=30, db_index=True) class School(models.Model): name = models.Charfield(max_length=50, db_index=True) majors = models.ManyToManyField(Major) class Professor(models.Model): ProfessorIDS = models.IntegerField() ProfessorName = models.CharField(max_length=100) ProfessorRating = models.DecimalField(decimal_places=2,max_digits=4) NumberOfRatings = models.CharField(max_length=50) school = models.ForeignKey(School , on_delete=models.CASCADE) major = models.ForeignKey(Major , on_delete=models.CASCADE) Notice that the School TABLE (Class) has a many-to-many for Majors, which is essentially what I want, the goal to have a database allowed to store multiple majors under an individual school. After doing some research I've come to conclusion that this doesn't make sense, it would be better to create a Bridge Table So I decided to create my model like so... from django.db import models class Major(models.Model): name = models.CharField(max_length=30, db_index=True) class School(models.Model): name = models.Charfield(max_length=50, db_index=True) class School_Majors(models.Model): school = models.ForeignKey(School, on_delete=models.CASCADE) major = models.ForeignKey(Major, on_delete=models.CASCADE) class Professor(models.Model): ProfessorIDS = models.IntegerField() ProfessorName = models.CharField(max_length=100) ProfessorRating = models.DecimalField(decimal_places=2,max_digits=4) NumberOfRatings … -

Could running a Heroku one-off dyno as `:detached` cause it to consume more memory?
When I run my management command in a detached one-off dyno, it exceeds the memory quota almost immediately. When I run non-detached, it works perfectly. I would like some insight as to how that could possibly be. Any answer that points to any documentation on this phenomenon would be amazing. This is for a Python management command (addfeederpolygons) that I estimate to use a few hundred megabytes of memory, as it does some intensive spatial joins with geodjango. Are there ways that the underlying code could perform differently in a detached one-off dyno vs. a non-detached one-off dyno? I expect the results to be the same, regardless of whether or not the dyno is running detached.

I am using below code to open a doc file and store the paragraphs as a string in a Django view. doc = docx.Document('media/%s'%(filename)) fulltext = [] for para in doc.paragraphs: fulltext.append(para) docdata1 ='\n'.join(fulltext) I am getting an error Typeerror: sequence item 0: expected str instance, Paragraph found
