Authenticate using email and uuid
I have a custom authentication model that contains a uuid field. In case the user forgets his password, a link will be sent to his email that will allow him to reset the password. The link contains the uuid. The form contains only password1 and password2 fields. Is there any way to change the password when user is not logged in ?(auth.authenticate cannot be used as the user does not remember his/her password.) If not, I want to authenticate using his email and uuid itself. How can it be done? -
Django AJAX POST login CSRF error in IE, EDGE, etc
I'm using Django 1.10. I want to log in via Jquery AJAX, but CSRF is set on. In order to pass the CSRF check, I have the following code. /* CSRF-config Start */ $.ajaxSetup({ beforeSend: function(xhr, settings) { function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) { // Only send the token to relative URLs i.e. locally. xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken')); } } }); $(document).ajaxSend(function( event, xhr, settings ) { if (settings.type == 'POST' || settings.type == 'PUT' || settings.type == 'DELETE') { function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); … -
Images on first load don't show on canvas
I want to pass a list of images and draw them each one for canvas. My view.py: def myview(request): ... lista=Myobject.objects.filter(tipo=mytipo) numero_oggetti = range(len(lista)) lista_formattata=[] for elem in lista: lista_formattata.append('/media/'+str(elem.myfield)) context_dict['lista']=lista_formattata context_dict['numero_oggetti']=numero_oggetti return render(request, 'mytemplate.html', context_dict) My template.html: <script> <!-- window.onpageshow = function() { myfunction({{lista|safe}}); }; --> </script> {% for c in numero_oggetti %} <canvas id='componenti_canvas{{ c }}' width='60' height='75' style="border:1px solid #000000;"> Your browser does not support the HTML5 canvas tag. </canvas> {% endfor %} My script.js: function myfunction(lista) { lista=lista for (i=0; i<lista.length; i++) { var canvas = document.getElementById('componenti_canvas'+i); var ctx = canvas.getContext("2d"); var base = new Image(); base.src = lista[i]; ctx.scale(0.5,0.5); ctx.drawImage(base, 0, 0); }; }; This code works but sometimes the images show, sometimes don't (all of them or no one). When I load the page they don't show, when I re-load the page they show up. If I wait some minutes and re-load they don't show again. I'm using firefox and in the console log when say GET image_name.png HTTP/1.0 200 they don't show (sometimes they are in cache, sometimes not... it don't make difference), when it don't say nothing they show. I tried: -setTimeout -call the list with an ajax request with cache: false, … -

Is using ISO-8601 date strings to compare against a DateField in Django's ORM officially supported and portable?
It seems that with Django's ORM I can consistently use an ISO-8601 date string instead of a datetime.date when querying against a model's DateField. For example, if I have a model like: from django.db import models class Sitting(models.Model): start_date = models.DateField() Then in my experience queries like the following work fine: Sitting.objects.filter(start_date='2015-12-25') Sitting.objects.filter(start_date__gte='2016-01-01') ... as well as: Sitting.objects.filter(start_date=datetime.date(2015, 12, 25)) Sitting.objects.filter(start_date__gte=datetime.date(2016, 1, 1)) My questions are: Is this officially supported, or might there be some underlying database for which using ISO-8601 strings doesn't work? I might well be missing something obvious, I couldn't find this documented anywhere - is there somewhere in the Django documentation that describes how values used in queries against DateField fields are used? -
Django & Postgresql: Override locale for sorting?
I have a simple Django app with a Postgresql database. The database is configured with nn_NO.UTF-8 locale. mything=>\l List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges -----------+----------+----------+-------------+-------------+----------------------- mything | postgres | UTF8 | nn_NO.UTF-8 | nn_NO.UTF-8 | =Tc/postgres + | | | | | postgres=CTc/postgres+ | | | | | me=CTc/postgres Let's say there's a table MyTable. I want MyTable.objects.order_by('name') to sort according to en_US rules, not nn_NO. Is it possible to override the sorting locale from Python/Django, or do I have to recreate the entire database? settings.py contains LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True -
Changing class of HTML element according to current file
I'm using Django and HTML files and I'm trying to change the class of one element depending on the current file. So, I have this base.html file, which is some kind of "super-class" file, which most of my other .html extends, thanks to Django, using {% extends 'base.html' %} Among other things, in that file, I have a navigation bar on top, which all files must have. This navigation bar has various elements, one of them being the current active element. For example, in the "foo.html" page, I'd like the navigation bar element holding to 'foo' tab to be underlined in red. I have a .css class for this, I just type class="active" and I'm good to go. But I'm in base.html. I can't. If I do, it's obviously active for every single child. Is there a solution for this or am I SOL? To be clear, I want foo.html to somehow tell base.html that "this div" should be active, while other files will tell base.html differently. Also, I would like some kind of clean solution, this is a long lasting project and I'd rather not start with any hacks. I know I could duplicate the navigation bar in all … -
Django send email in parts to avoid overhead
I have a non-profitable website that I need to handle newsletter emails to probably thousand people (lets be realistic and give an upper bound of at most 2000 - 2500 registered users). I have implemented email this way: @login_required def SendEmail(request): receivers = [] users = Users.objects.all() receivers.append(user.Email for user in users) emailTypeSelected = request.POST.get('email_type', -1) email_factory = EmailFactory() emailManager = email_factory.create_email(emailTypeSelected) emailManager.prepare("Some Title") emailManager.send_email_to(receivers) return render(request, 'new_user_email.html') And here is the "abstract" class. class Email(object): title = "" plain_message = "" html_message = "" def send_email_to(self, receivers): send_mail( self.title, self.plain_message, SENDER, receivers, html_message=self.html_message ) I have tested this code and it takes a while to send 1 email to 1 user. My concern is that for thousand emails will put a big overhead to the server. I was thinking to do the following: Break the users into group of 100 and send email to those users every 30 minutes. But I am not sure how this can be implemented. Seems that I will need to implement a sort of threads that will be triggered independently and handle the email for me. Is there any design pattern that you are aware on how to solve this problem? Now I know … -
Why does Django not update my models?
I'm trying to update my SQLite3 database with ./manage.py shell like so: >>> objs = Model.objects.all() >>> for obj in objs: ... obj.set_current_language('ru') ... obj.full = obj.full.replace("foo", "bar") ... obj.save() ... print obj.full I get some string with bar on output, but it doesn't seem my database was actually updated, because on the website it is still some string with foo. Why so? -
Django admin ManyToManyField add button and list display

How to add "+" button in CityAdmin above m2m widget? Currently what i have: 2. Is it possible in CityAdmin m2m widget have some list display where I can see image thumbnail? Ideally like in ImageAdmin: What I have tried: In Image model __unicode__ function return '<img src=%s />' %self.image.icons['64'], but then in admin it just displays raw text. -
How to make Django button appear with javascript?
This is my code: {% extends "global/Base.html" %} {% load otree_tags %} {% block title %}Chart{% endblock title %} {% block content %} {% next_button %} {% endblock %} {% block scripts %} <script> //scripts </script> {% endblock %} I would like to make {% next_button %} not visible at first, then appear with javascript.

Django rest framework CRUD API for model with foriegn key elements
Okay so here I am with another problem I'm facing with Django. This time it's the REST framework. I have a Model with Foreign Key dependencies in my project. I had to retrieve the foreign key field as an object, not just an ID field and was successful in that using Serializer Relations. So my Serializer.py looks like: class EventSerializer(serializers.ModelSerializer): owner = EventUserSerializer(read_only=False) severity = EventSeveritySerializer(read_only=False) type = EventTypeSerializer(read_only=False) cause = EventCauseSerializer(read_only=False) subcause = EventSubcauseSerializer(read_only=False) impact = EventImpactSerializer(read_only=False) point_location = PointLocationSerializer(read_only=False) class Meta: model = models.Event fields = ('id', 'description', 'owner', 'status', 'severity', 'type', 'cause', 'subcause', 'impact', 'is_public', 'occurrence_time', 'reporting_agency', 'estimated_duration', 'confirmed_timestamp', 'rejected_timestamp', 'closed_timestamp', 'point_location', ) Making a GET request, I get the result I wanted: { "meta": { "count": 1, "previous": null, "next": null }, "results": [ { "id": 8, "description": "test event 1", "owner": { "user": { "id": 1, "username": "venus", "email": "venus.saini@ibigroup.com" } }, "status": "confirmed", "severity": { "id": 2, "created": "2016-08-24T07:27:24.722000Z", "modified": "2016-08-24T07:27:24.723000Z", "name": "Severe", "is_enabled": true, "sortorder": 1 }, "type": { "id": 2, "created": "2016-08-24T07:27:45.203000Z", "modified": "2016-08-24T07:27:45.204000Z", "name": "Accident", "event_category": "unplanned", "sortorder": 2 }, "cause": { "id": 2, "created": "2016-08-24T07:28:16.088000Z", "modified": "2016-08-24T07:28:16.092000Z", "name": "Whether Conditions", "sortorder": 3, "event_type": 2 }, "subcause": { "id": 2, "created": … -
JWT Signature Validation Failed after deploying new backend version to server

django authorization without using request.user.is_authenticated()

Celery and Flower, with Django and Redis, No queues info in 'Broker' tab
I'm using celery with Django, redis as broker. But I'm unable to get queues info in flower. Searched this problem for two days but got no solution. Please help. In "Dashboard"/"Tasks" tab, everything seems fine, the numbers are updating in realtime. But in "Broker" tab, the message number of queues are all 0 and one queue is missing. I've checked redis, the usage shows it is impossible that every queue is empty. The "Queued tasks" graph in the "Monitor" tab is always empty while the rest of the four graphs are working.

Django admin many to many horizontal filter not working

Now, I've added some custom html to my change_form.html so simply adding a filter_horizontal = ('teams', 'players', ) is not helping.

Currently, I am getting an error like Not a Valid Choice If Choice is Not in The Database. How is this possible.
