Hi I am translating a website in hungarian, I have problems with alerts and confirm strings that i have in my templates . am using "gettext('')" but these strings are not appearing in po files .enter code here my urls.py urlpatterns = patterns('', url(r'^jsi18n/$', javascript_catalog, js_info_dict, name='javascript-catalog'),` I have created po file django.po by running makemessages it has all the strings marked as trans in templates and also strings from *.py files. then I have run following command django-admin.py makemessages -d djangojs -l hu_HU its creating djangojs.po. The strings appearing in this file are all from *.js files in my static folder. But how do i have my strings used in alerts and confirms that are written in my templates. here are snippets from my templates. enter code here if($('#id_action').val()=='DEL'){ if(confirm(gettext('Are you sure you want to delete selected author(s) ?'))){flag_action=true;} } In my template i also have something like this which is not appearing in po files either. <li><a onclick="if(confirm(gettext('Are you sure you want to delete the selected author?'))){filter_content({{auth.id}},'DEL');return false;}" href="javascript:void(0)">{% trans 'Delete' %}</a></li> The string in gettext is not appearing in any po.

what could cause html and script to behave different across iterations of a for loop?
I'm trying to build a side navigation bar where categories are listed and upon clicking a category a respective sub list of subcategories is shown right below the category. And if the category is clicked again, the sub list contracts. So I'm running a loop across category objects. Inside this outer loop, I'm including a an inner loop to list subcategories and a script that hides the submenu and slidetoggles it only when a category is clicked. I'm using django template tags to dynamically assign class names for my html elements and also to refer to them in the script. So after all for loop iterations, there is a list of subcategory and a dedicated script for each category and they have unique class names so no chance of an overlap. So the weird part is, this works perfectly for most categories, but some of the categories and their submenu remain open and when clicked on the category the page reloads. I don't get it, what could cause the exact same code (run in a for loop) to behave so differently? -
Django uploaded file permissions
How to add permissions to uploaded file? E.g class Car(models.Model): name = models.CharField(max_length=255) photo = models.ImageField(upload_to='cars') owner = models.ForeigKey(AuthUser) And each logged user can add te images. E.g. User1 added image a.jpg. And can access it by adresserver.com/cars/a.jpg but anyone can access it too. How add permissions to only owner can see the image? -
How to prevent Django Rest Framework from validating the token if 'AllowAny' permission class is used?
Let me show you my code first: In settings.py .... DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', ) .... My my_view.py: @api_view(['POST']) @permission_classes((AllowAny,)) def say_hello(request): return Response("hello") As you can see, I'm using Token Authentication to protect my other API's by default, but when I add a token header in say_hello, Django Rest Framework will also check if the token is valid or not, even when i add AllowAny permission class. My question is how to make Django Rest Framework ignore checking the token if the token header is present in the say_hello? and Is there any security considerations for making this? Thanks. -
Need additional field for models on indirect relation
I've created a high school race django app. I have three models, Race, split and Athlete. Of which Split flows through Split Filter to dictate a filtering script we run. I was just asked to add a new field of Frosh vs JV vs Varsity. This creates a huge problem for me, because we're not sure where to add it. There can be JV and Varsity runners in the same race. These runners are registered in our system, and change races week to week, so we can't add it on athlete. We are considering adding it on split, but there are multiple splits per person (laps) per race, and in some weird circumstances, some splits can belong to different races (ie. a kid is in two races at the same time). Athlete and race aren't directly related on a Foreign key, so it makes this very difficult to figure out where and how to add JV vs. Varsity. class Race(models.Model): name = models.CharField(max_length=50) splits = models.ManyToManyField(Split, through='SplitFilter') class SplitFilter(models.Model): race = models.ForeignKey(Race) split = models.ForeignKey(Split) filtered = models.BooleanField(default=False) class Split(models.Model): athlete = models.ForeignKey(Athlete) time = models.BigIntegerField() class Athlete(models.Model): user = models.OneToOneField(User) birth_date = models.DateField(null=True, blank=True) gender = models.CharField(max_length=1, null=True, blank=True) … -
Modyfing pdf and returning it as a django response
I need to modify the existing pdf and return it as a response in Django. So far, I have found this solution to modify the file: def some_view(request): # Create the HttpResponse object with the appropriate PDF headers. response = HttpResponse(content_type='application/pdf') response['Content-Disposition'] = 'attachment;filename="somefilename.pdf"' packet = StringIO.StringIO() # create a new PDF with Reportlab can = canvas.Canvas(packet, pagesize=letter) ##################### 1. First and last name first_last_name = "Barney Stinson" can.drawString(63, 686, first_last_name) #Saving can.save() #move to the beginning of the StringIO buffer packet.seek(0) new_pdf = PdfFileReader(packet) # read your existing PDF existing_pdf = PdfFileReader(file("fw9.pdf", "rb")) output = PdfFileWriter() # add the "watermark" (which is the new pdf) on the existing page page = existing_pdf.getPage(0) page.mergePage(new_pdf.getPage(0)) output.addPage(page) # finally, write "output" to a real file #outputStream = file("output.pdf", "wb") #output.write(outputStream) response.write(output) outputStream.close() return response It let's me download the pdf, but when I am trying to open it, I get the message, that the file is damaged or wasn't correctly decoded. Does anyone know what am I don't wrong? Thank you! -
Django 1.9.7 Admin pages - CSS loaded but not rendering
I'm trying to get started with Django but already have something trivial bugging me. The localhost:8000/admin page should give me page with rendered elements using the login.css and base.css styles. However, the styles are not applied. Because my .css files are actually loading, I'm not even sure it's related to Django. Any insight on what could be causing the issue greatly appreciated.

Strange mistake in .aggregate with Case
I have two models: UserProfile BalanceEntry | - user = models.ForeignKey(UserProfile) - models.CharField(max_length=32, db_index=True, choices=BALANCE_ENTRY_TYPES) - amount = models.FloatField() - added_dt = models.DateTimeField(auto_now_add=True) I want to get total user revenue for last N days, so I created this method: def get_revenue_with_delta(self, days_delta): now = timezone.datetime.now() earlier = now - timezone.timedelta(days=days_delta) return int(BalanceEntry.objects.filter(user=self).aggregate(sum=Sum( Case( When(Q(type=BALANCE_ENTRY_TYPE_REFILL) & Q(added_dt__gt=earlier), then='amount'), default=Value(0), output_field=models.FloatField() )))['sum']) I have seeded the DB with fake UserProfiles and BalanceEntries for them yesterday, so all of them have the same added_dt. Then I'm trying to test the method get_revenue_with_delta for these profiles with days_delta = 7 and days_delta = 30. And I'm getting different amounts! Where is the mistake? -
AngularJS Logging Out and Logging back in
I have an index file that has some directives- <div ng-if="$hide"> <ba-sidebar></ba-sidebar> <page-top></page-top> <div class="al-main"> <div class="al-content"> <content-top></content-top> <div ui-view></div> </div> </div> </div> <div ng-if="!$hide"> <login-view></login-view> </div> What this does is it shows the content if a user successfully logs in. The code for logging in is- $interval(function(){ var token = $cookies.get('token'); if(token === undefined){ $rootScope.$hide = false; } else{ $rootScope.$hide = true; } }, 300) The interval function keeps a check on cookies for token that is send from the backend(django) and switches the views. If there is a token, it shows the main content, if not, it loads up the log-in directive. To log out, what I do is delete these cookies and set them to null, which automatically changes the view back to log-in directive. Once logged out, page switches to log-in. The problem- When I try to log-in with a different user, at the backend, the user gets switched but as soon as the view changes to the main content, it loads up the data from the previous user until whole page is refreshed(manually). I do not seem to understand why as ng-if recreates the whole DOM, shouldn't it load up the new data? If not, … -

Django REST Framework: Setting up prefetching for nested serializers
My Django-powered app with a DRF API is working fine, but I've started to run into performance issues as the database gets populated with actual data. I've done some profiling with Django Debug Toolbar and found that many of my endpoints issue tens to hundreds of queries in the course of returning their data. I expected this, since I hadn't previously optimized anything with regard to database queries. Now that I'm setting up prefetching, however, I'm having trouble using making use of properly prefetched serializer data when that serializer is nested in a different serializer. I've been using this awesome post as a guide for how to think about the different ways to prefetch. Currently, my ReadingGroup serializer does prefetch properly when I hit the /api/readinggroups/ endpoint. My issue is the /api/userbookstats/ endpoint, which returns all UserBookStats objects. The related serializer, UserBookStatsSerializer, has a nested ReadingGroupSerializer. The models, serializers, and viewsets are as follows: models.py class ReadingGroup(models.model): owner = models.ForeignKeyField(settings.AUTH_USER_MODEL) users = models.ManyToManyField(settings.AUTH_USER_MODEL) book_type = models.ForeignKeyField(BookType) .... <other group related fields> def __str__(self): return '%s group: %s' % (self.name, self.book_type) class UserBookStats(models.Model): reading_group = models.ForeignKey(ReadingGroup) user = models.ForeignKey(settings.AUTH_USER_MODEL) alias = models.CharField() total_books_read = models.IntegerField(default=0) num_books_owned = models.IntegerField(default=0) fastest_read_time = models.IntegerField(default=0) … -

Change to Django model not detected by makemigrations
I have a Django model which is referenced in another model as a ForeignKey type. In order that this is displayed nicely in the admin interface I added a __unicode__ method, like this: class Foo(models.Model): label = models.CharField(max_length=2) description = models.TextField() def __unicode__(self): return self.label This change is immediately visible in the admin interface after saving my models.py file. But when I run makemigrations it returns No changes detected in app 'concert'. Running migrate does nothing, as it doesn't see any changes, and python manage.py check returns System check identified no issues (0 silenced). Should I expect this? I've made many changes to my models and so have run many migrations, but I've never encountered this before. Currently running Django 1.8.3 with Sqlite development db, under Python 2.7 on Windows. -
What benefit to society are movies about slavery like Amistad and Django Unchained?
Sonya AbarcarThere is considerable benefit. They are very informative. They educate. Entertainment is provided as well. I would have never known about Amistad if it weren’t for this movie. Period. Many people would probably agree with that sentiment. Movies are often stories that need to be told and the former is definitely a story that needed to be told.Sure, they are painful but they don’t worsen race relations. Racism worsens race relations. Not movies, books, or songs. People do that.See Questions On Quora -

Setting a cookie in Django Rest Framework API
I am trying to set a cookie on my website when a GET request is made to an API end-point. In my urls.py, I have this: url(r'^api/cookies/$', views.cookies, name='cookies'), which points to this view: @api_view(['GET']) def cookies(request): if request.method == 'GET': response = HttpResponse('Setting a cookie') response.set_cookie('cookie', 'MY COOKIE VALUE') if 'cookie' in request.COOKIES: value = request.COOKIES['cookie'] return Response('WORKS') else: return Response('DOES NOT WORK') In other words, when this view is loaded through a GET method, I am setting a cookie. If the cookie is set properly, I return 'WORKS', otherwise, I return 'DOES NOT WORK'. Now, I am sending a GET request to this URL, and I get 'DOES NOT WORK', which means the cookie is not set properly. What am I doing wrong? How can I fix this? Note: I am using Django Rest Framework for my views. -

How would I create a form for a foreign key field that has a drop down menu with an 'add item' option in django?
I'll start with my model fields: class Store(models.Model): name = models.CharField(max_length=250) def __str__(self): return self.name class Product(models.Model): type = models.CharField(max_length=250) def __str__(self): return self.type class Receipt(models.Model): store = models.ForeignKey(Store) date = models.DateField() line_items = models.ManyToManyField(Product, through='ReceiptProduct') def __str__(self): return self.store.name + ': ' + str(self.date) class ReceiptProduct(models.Model): receipt = models.ForeignKey(Receipt) product = models.ForeignKey(Product) price = models.FloatField() description = models.CharField(max_length=500, null=True, blank=True) def __str__(self): return self.product.type What I would like to do is create a form for the ReceiptProduct model. class AddItemForm(ModelForm): class Meta: model = ReceiptProduct fields = ['product', 'price', 'description'] Done. And the view? def add_receipt_product(request, receipt_id): current_receipt = Receipt.objects.get(id=receipt_id) if request.method != 'POST': # No data submitted; create a blank form. form = AddItemForm(initial={'receipt': current_receipt}) else: # POST data submitted; process data. form = AddItemForm(data=request.POST) if form.is_valid(): new_product = form.save(commit=False) new_product.receipt = current_receipt new_product.save() return HttpResponseRedirect(reverse('purchase_log:receipt_details', args=[receipt_id])) context = {'current_receipt': current_receipt, 'form': form} return render(request, 'purchase_log/add_receipt_product_form.html', context) Okay, so what I would like to do is, under the 'product' field (which is a drop down menu populated by the Product model), have an option called, maybe, 'custom product' or something, that the user can select to add an item to the Product model and will then appear in … -
Micro-components architecture with python / Django / Drf

Creating a Quote form in Django
i am creating a django powered website. Specifically, a courier website. I need to create an application that serves as a quoting app. The user will type in the dimensions of the package into a form and after submitting the form, a price/quote will be returned , based on the dimensions inputted. I have done this so far (views.py) from django.shortcuts import render, redirect from quote.forms import QuoteForm def quoting(request): if request.method == 'GET': form = QuoteForm() else: form = QuoteForm(request.POST) if form.is_valid(): Length = form.cleaned_data['Length'] Breadth = form.cleaned_data['Breadth'] Height = form.cleaned_data['Height'] return redirect('thanks') return render(request, "quote/quote.html", {'form': form}) (forms.py) from django import forms class QuoteForm(forms.Form): Length = forms.Integer() Breadth = forms.Integer() Height= forms.Integer() (quote.html) {% extends "shop/base.html" %} {% block content %} <form method="post"> {% csrf_token %} {{ form }} <div class="form-actions"> <button type="submit">Send</button> </div> </form> {% endblock %} Then i am aware i am lacking an html that would display the answer.
