@csrf_protect in django services
I'm trying to use @csrf_protect in my services by following Cross Site Request Forgery protection article but it is not working for me. This is my settings file MIDDLEWARE_CLASSES = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'corsheaders.middleware.CorsMiddleware', 'CB_Core_App.customMiddleWare.middleWare.IPValidationMiddleWare', ] and this is how I'm Acquiring the token var csrftoken = Cookies.get('csrftoken'); And this is how I'm configuring the $http provider with the cookie and header names: $httpProvider.defaults.xsrfCookieName = 'csrftoken'; $httpProvider.defaults.xsrfHeaderName = 'X-CSRFToken'; But when I call any service, it returns 403 forbidden error. Any Idea what I'm missing or doing wrong? Any kind of help will be appreciated. -
How to add description to Django command?
In argparse, the description is passed into the ArgumentParser ctor like so: import argparse parser = argparse.ArgumentParser(description="Print a number") parser.add_argument('-n', dest='number', action='store', type=str, help="The number to be printed") args = parser.parse_args() When doing a similar thing using a Django command, how does one add the description="Print a number" given that the ArgumentParser has already been constructed? from django.core.management.base import BaseCommand class Command(BaseCommand): def add_arguments(self, parser): parser.add_argument('-n', dest='number', action='store', type=str, help="The number to be printed") -
Django reserve foreign key in views
I have a reverse query in a template that working on two tables connected together with Foreign Key. That query is giving result what I want for now but in the future, it is clear will cause me serious problems about query optimization.

How can logger.removeHandler(logger.handlers[0]) throw ValueError: list.remove(x): x not in list?
I'm trying to debug an exception in someone else's Python code, and I am not an expert in Python. The code tries to flush and remove all handlers on a standard Python Logger: def restart_logging(logger_id): logger = logging.getLogger(logger_id) while logger.handlers: handler = logger.handlers[0] handler.flush() logger.removeHandler(handler) init_logging(logger_id) This raises an exception: File "/usr/lib64/python2.6/logging/__init__.py", line 1208, in removeHandler self.handlers.remove(hdlr) ValueError: list.remove(x): x not in list I've reviewed StackOverflow's other "x not in list" questions, and they all fit in these two categories: removing the same item more than once (usually because of doing for x in list: list.remove(x) rather than while list: list.remove(list[0])) remove an item that was never in the list I don't see how either applies here. Firstly, a while loop is used: while there are still handlers, take the first one (which succeeds or there'd be an IndexError), flush it, remove it. Even if that removed more than one entry in the list, it's a while loop testing if the list still has entries, not a for loop iterating over (potentially removed) objects. Looking at the logging module source, it only calls remove() once, and it even checks the handler is in the list immediately before calling remove(): def … -
Reorder Django QuerySet by dynamically added field
A have piece of code, which fetches some QuerySet from DB and then appends new calculated field to every object in the Query Set. It's not an option to add this field via annotation (because it's legacy and because this calculation based on another already pre-fetched data). Like this: from django.db import models class Human(models.Model): name = models.CharField() surname = models.CharField() def calculate_new_field(s): return len(s.name)*42 people = Human.objects.filter(id__in=[1,2,3,4,5]) for s in people: s.new_column = calculate_new_field(s) # people.somehow_reorder(new_order_by=new_column) So now all people in QuerySet have a new column. And I want order these objects by new_column field. order_by() will not work obviously, since it is a database option. I understand thatI can pass them as a sorted list, but there is a lot of templates and other logic, which expect from this object QuerySet-like inteface with it's methods and so on. So question is: is there some not very bad and dirty way to reorder existing QuerySet by dinamically added field or create new QuerySet-like object with this data? I believe I'm not the only one who faced this problem and it's already solved with django. But I can't find anything (except for adding third-party libs, and this is not an … -

Django asset manager for Views or template tags?
I come to Django having used the Yii2 PHP framework. One of the good features about that is it allows you to create asset files for CSS and JS which are then loaded into the base layout file at runtime. This allows you to keep the base template clean of CSS and JS markup within the head and at the bottom of the HTML document. The CSS and JS files you specify in the asset file are automatically placed in the correct position in the document and you can also specify dependencies if needed. At the moment, with Django I am having to edit the base.html file manually which is not ideal. I know you can use the Media class for forms, and in admin.py, which does a similar job. However, what I would like to do is to something like this (for example) in inclusion template tags or in a class based view perhaps. Is this possible? Many thanks! -

Webpack TypeScript and xgettext translations
I have a Django app and am using Django's i18n module to help translating my strings. For translating JavaScript, I run python manage.py makemessages -d djangojs which adds all marked strings to a .po file. This works quite well for all my boring .js files in my static folder. However, we are starting to use webpack to pack some typescript (.tsx files) into a bundle.js file. This file is copied to the static folder after building, so I expected Djangos makemessages to pick up the strings from it as well. However, it seems that the strings are not parsed correctly, because most of the code in bundle.js is simply strings wrapped in eval(). I believe this means that I need webpack to - in addition to the bundle.js file - create a .js file for each .tsx file without all of the eval() nonsense, so that django's makemessages can parse it properly. I have no idea how to do this, however. My current config looks like this var path = require("path"); var WebpackShellPlugin = require('webpack-shell-plugin'); var config = { entry: ["./src/App.tsx"], output: { path: path.resolve(__dirname, "build"), filename: "bundle.js" }, devtool: 'source-map', resolve: { extensions: [".ts", ".tsx", ".js"] }, module: { … -
