How to put valid input in a ModelChoiceField widget that inherits TextInput widget

Not Found url in django class based view with ajax
I have a problem with "like" functionality. I want to make it possible to like the post, without overloading the whole page. So I used CBV django connected to ajax. My problem is that it receives: Not Found: /like/ by pressing the "Like" button. My view: class PostLikeView(generic.View): def post(self, request): post = get_object_or_404(Post, id=request.POST.get('id')) is_liked = False if post.likes.filter(id=request.user.id).exists(): post.likes.remove(request.user) is_liked = False else: post.likes.add(request.user) is_liked = True context = { 'post': post, 'is_liked': is_liked, 'total_likes': post.total_likes(), } if request.is_ajax(): html = render_to_string('post/like_section.html', context, request=request) return JsonResponse({'form': html}) Below is jquery code: <script type="text/javascript"> $(document).ready(function(event){ $(document).on('click', '#like', function(event){ event.preventDefault; var pk = $(this).attr('value'); $.ajax({ type: 'POST', url: "{% url 'post:post_like' %}", data: {'id': pk, 'csrfmiddlewaretoken': '{{ csrf_token }}'}, dataType: 'json', success: function(response){ $('#like-section').html(response['form']) console.log($('#like-section').html(response['form'])) }, error: function(rs, e){ console.log(rs.responseText); }, }); }); }); </script> url to view: url(r'^like/$', login_required(PostLikeView.as_view()), name='post_like'), code in html: <form action="{% url 'post:post_like' %}" method="post"> {% csrf_token %} {% if is_liked %} <button type="submit" id="like" name="post_id" value="{{ post.id }}" class="btn btn-danger">Dislike</button> {% else %} <button type="submit" id="like" name="post_id" value="{{ post.id }}" class="btn btn-primary">Like</button> {% endif %} </form> I would like the button to work on the principle of not reloading the whole page. -
Django: how to store a lot of data between requests if I don't have a database
I am writing an app that will visualize Strava (social site for athletes) user's activities in various ways. The user is required to authenticate with his Strava account, and then my app downloads his activity data from Strava API. As there will be no user accounts in my app - just the Strava authentication - I have decided to not use a database. Therefore, I would need to store the activity data in memory. The data would be quite big: for example, I have 800 activities on Strava, each being a longish JSON. Would storing the data in session like session['activities'] = some_downloaded_activities be suitable for this? I would then set up API endpoints that would query this session data, filter it as required by the front end of my application and return it. My other idea is to use a database only to store the JSON file, but delete the data immediately after the user session is done - but it seems like an overkill. Or is there a better approach? -
if condition on large querysets are very slow
I am using Python 2.7 and Django 1.9.2 I am trying to do a condition where if queryset is not empty, there will be a functionality. I realized something as my queryset has gone large up to 56,000 records. A simple condition with that queryset takes almost 5 seconds but if I added .exists() with the queryset it is just so fast. Please check snippet bellow from record.models import Record records = Records.objects.filter(result=0) if records: # this takes almost up to 5 seconds with 56,000 records # do stuff here With .exists(): from record.models import Record records = Records.objects.filter(result=0) if records.exists(): # very fast abd just takes milliseconds # do stuff here Any explanation why the first one is so slow? I'm beginning to think that the first one loops the value of the records variable when doing an if -
Invalid template library specified. ImportError raised when trying to load 'src.myapp.templatetags.custom_tags' cannot import 'custom_tags'
I have deployed my django project over windows 2012 IIS. After the setup sometimes its failing to load the template tag libraries. With the template tag loading error i am also receiving an error like below in my chrome firebug console. Mixed Content: The page at 'https://10.***.***.**/site/new_site/list/?id=4' was loaded over a secure connection, but contains a form that targets an insecure endpoint 'http://dpaste.com/'. This endpoint should be made available over a secure connection. I searched my entire code i cannot see any mix uup code between http and https. Also i tried to put SECURE_SSL_REDIRECT = True in my settings.py file, but as i am not using a any secure connection its failed to load the site. I tried this but its does not resolve my issue. I am not that much aware of this IIS+django settings. Should i do any separate settings in order to load the template tag libraries. But i am not getting this error message often. Any help would be greatly appreciated. Thanks. I am also attaching the error messages i am getting . -

integrating django with aiohttp/asyncio
i want to integate django with aiohttp/asyncio for asynchronous programming and for websockets handling, i know django has celery & django-channels to do asynchronous task and websocket server respectively but aiohttp is having both asynchronous and websocket server pre built in it and i found that framework more scalable and easy when compared to celery/django channels while creating a function to webscrapping(i don't know if webscrapping can be possible in celery i havent tried it yet ) and it also supports async and await perfectly but my question is how can we implement both django and aiohttp in a project instead using django's development server can we use aiohttp server to serve the site and can we able to integrate django with aiohttp function (like lets take an example if i want to scrap a website of user submmited input to my database can i use this await calls in my function while fetching the website and posting the following website to my django database or post the function results to another django function) and i want to know the disadvantages of integrating ,if any ?? and while posting your answer please could you post a sample practical example of … -
Django rest framework and getting serializer values using source keyword
I have two models, one is just the base User model and the other is Profile model that is used to extend the User model and keep more details. Here's what the UserSerializer looks like: from django.contrib.auth.models import User from profiles.models import Profile from rest_framework import serializers class UserSerializer(serializers.ModelSerializer): reputation = serializers.IntegerField( read_only=True, source='profile.reputation' ) class Meta: exclude = ('password',) model = User def create(self, validated_data): password = validated_data.get('password') user = User.objects.create(**validated_data) user.set_password(password) user.save() Profile.objects.create(user=user) return user As you can see, this overrides the create method so it can make a profile record with each create. There is also a reputation field being added to the serializer so when I get the User it comes with its reputation from the profile. That reputation field is defined on the Profile model. This got me thinking, is it possible to override create in such a way that allows me to send data to one endpoint and create profiles in one go? For instance, right now if I want to create users and I just send a POST request to my endpoint with: { "username": "sethen", "password": "password" } And I get back the correct profile. If I were to add a bio … -

Django extend AbstractBaseUser Admin Login Page Error
Today I tried to change the UserModel, So I did everything that was supposed to be needed : create the class class User(AbstractBaseUser, PermissionsMixin): With something like that inside : phone = PhoneNumberField(unique=True) is_admin = models.BooleanField(default=False) is_active = models.BooleanField(_('active'), default=True) objects = UserManager() USERNAME_FIELD = 'phone' REQUIRED_FIELDS = [] def is_staff(self): return self.is_admin The UserManager : class UserManager(BaseUserManager): use_in_migrations = True def _create_user(self, phone, password, **extra_fields): """ Creates and saves a User with the given phone and password.

My project uses the Google+ API to login,which is deprecated now, need tips/advice to update
I have a project currently deployed, in production, which uses the google+ API and the python social core (Django) (social_core) to login almost all users, now the google+ apis are deprecated and I need to update the authentication system. Any tip, documentation or tutorial I can follow to make it? I followed this tutorial to make the initial login but now that won't work in the near future. This is a school project so I'm pretty much the only developer working with this, any help provided will be much appreciated :D -
get_queryset vs manager in Django
As far as I know, we bring the database by model managers right? e.g. queryset = Model.objects.all() But sometimes, I see some code that seems almost same thing but is a bit different, post = self.get_queryset() which also fetches database but not by manager. What's the difference between fetching database by manager and get_queryset() and their usage? -
ModuleNotFoundError in Django Crontab Command
I have a number of django custom commands which work. However, when I have tried to automate them using crontab, my error log records the following error: ModuleNotFoundError: No module named 'sanct' I have added the virtualenv path to crontab command path. I have a test command which just creates a log file every minute and this seems to execute properly. I'd like the crontab commands to execute. My crontab commands are as follows: job = cron.new(command='/home/arch/myprojectdir/myprojectenv/bin/python /home/arch/myprojectdir/sanct/management/commands/cong_dl.py >>/tmp/out.txt 2>&1')
