Processing file uploaded by jquery fileupload
I've followed the tutorial for jquery fileupload the code I've written is below $('#image_file').fileupload({ dataType: 'json', type: 'post', url: '/whats-on/upload-event/?v='+event_id, contentType: "application/json; charset=utf-8", done: function (e, data) { console.log('done'); } }); It returns an error ValueError: No JSON object could be decoded Here's the python function it fails when it tries @csrf_exempt def create_event(request): context = RequestContext(request) response_data = {} response_data['status'] = False if request.FILES: file = request.FILES[u'files'] response_data['status'] = True elif request.method == 'POST': data = json.loads(request.body) It doesn't go through request.FILES and fails when it reaches data = json.loads(request.body) -
Django - Html page with multiple parts, updating on selection
I want to create a page with basically 4 "parts" A radio button list, with values based on search results A text area that gets updated based on what was selected in the radio button section Another radiobutton list, that changes based on what was selected in list 1. Another text area, updates based on list 2's selection As an example. List 1 could be Dogs Cats Parrots If you select dogs, the text area will say: "mans best friend, they bark" List 2 would then say: Poodle Foxterrier Then selection poodle the 2nd text area will say "short white haired dog" Can this be done through using forms/widgets? I'm quite new to Django so I'm not sure what would be the best way to do this, as it has to be a non javascript solution. -

Django - choice set, but no drop down in form
I would like to have a choice set in my model for template and validation. However, in the model.form for that model I want to have just an integer field. How can I change the widget in order to just get a InputField? I tried to change the widget to forms.Model, but that did not seem to work.

Removing Inconsistency in django web app
I am working on making an online two player tic-tac-toe game. I am using django framework for it. Since I am making the tic-tac-toe table(data structure to store state of game) global in my views, it leads to inconsistent state when the app is opened by more than one client at same time. Working of my app: The user is given a choice to play first or not. He submits his choice. His choice is decoded by 'chance' view. The user then starts playing and clicks on certain box on the board. This move is decoded by 'index' view. Then computer's move is computed and is then displayed on the board. But when two users play the game simultaneously, both are changing the same global table or board. I cannot make it as local variable since the previous data will be lost. How do I store the data for each user and use it? Views code: from django.shortcuts import render from django.http import HttpResponse from django.http import Http404 from django.http import JsonResponse from random import randint from django.views.decorators.csrf import csrf_exempt xpos = -1 ypos = -1 start = 0 a = [[0 for x in range(3)] for x in range(3)] … -

Django Patch Side effect IntegrityError not being raised

Django How can I use redis in Windows10?
I am developing small system with Django framework and Windows 10. I am going to use Redis for caching on memory. Well, I found that Redis doesn't support Windows OS officially but MsOpenTech provides a package for Windows 64 bit. I installed it with chocolatey package manager. https://chocolatey.org/packages/redis-64 Then I installed django-redis package by pip install in cmd. Well, It automatically installed redis module at the same time. I thought it would be fine to delete redis module because I already installed redis 3.0.503 64 bit(for Win). But it occured error "no mudule named 'redis'". I checked django-redis directory "django_redis-4.5.0-py3.4.egg-info". There was one line 'redis>=2.10.0' in 'requries.text' file. so I assumed django-redis is set to need redis 2.10.0 as default. well, then I just installed redis by pip install redis in cmd. After setting in Django, I saved some key value data as test on redis. (by using cache_page decorator) CACHES = { "default" : { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": "redis://127.0.0.1:6379/1", "OPTION": { "CLIENT_CLASS": "django_redis.client.DefaultClient", }, "KEY_PREFIX": "Test" } } I connected to redis. redis-cli -n 1 I checked keys 127.0.0.1:6379[1]> keys * result was like this. empty (empty list or set) then I put test data on redis by cache_page … -
django rest framework - Nested serialization not including nested object fields

How to prefetch a list of unique values from a related Django model?
I'd like to prefetch a list of unique values from a related model in Django in as few queries as possible. For instance, consider the following : class A(models.Model): b = models.ForeignKey('B') value = models.CharField(max_length=10) class B(models.Model): pass I'd like to annotate each model instance of a queryset on B, with a list of unique values from the value column in the related A objects. >>> qs = B.objects.all().annotate(distinct_a_values=...) >>> [a.value for a in qs.first().a_set.all()] ["value_1", "value_2", "value_1"] >>> qs.first().distinct_a_values ["value_1", "value_2"] The closest I could find was to use a Prefetch object : >>> qs = B.objects.all().prefetch_related( Prefetch( 'a_set', A.objects.all().distinct('value').only('value', 'b_id'), to_attr='distinct_a_values' ) ) It works, but feels clunky, and it is definitely weird to get a list of A objects, only to discover that they are distinct on something other than the primary key. Any other way? -
