Django / Ajax - How to filter and display result based on selection
I am trying to filter and display data in Django based on the selection made by the user from drop down box. I'm using ajax call to send a request to Django views. When a user selects, for example, Airline A, then Ajax will send the 'value' of that selection which is an integer to Django backend to filter data and send it back to frontend. Here is my code: HTML: <form method="GET"> <select id="airline-selected"> {% for airline in airline_list %} <option value="{{ airline.id }}"> {{ airline.name }} </option> {% endfor %} </select> <input type="button" value="Update" id="selection-button" method="GET"> </form> Ajax: <script> $( "#selection-button" ).click(function(event) { event.preventDefault(); var airlineSelected = $('#airline-selected').find(":selected").val(); $.ajax({ url: "{% url 'charts_data' %}", method: 'GET', filter_category: parseInt(airlineSelected), success: function(data){ console.log(data) }, error: function(error_data){ console.log("error") console.log(error_data) } }) }); </script> Views.py: class ChartData(generics.ListAPIView): serializer_class = FinancialDataSerializer def get_queryset(self, *args, **kwargs): filter_category = self.request.GET.get("filter_category") queryset = FinancialData.objects.filter(airline_id=filter_category) queryset_filtered = queryset.filter() return queryset_filtered My console.log(data) is showing an empty Array which means views are not getting filtered. How can I filter and display the data based on the selection made by the user? -
Can you modify a model field within a for loop?
I'm trying to write a method that converts temperature units so I can display si units on demand without modifying the database. When I load the view, Currently converts properly as it's not done within a for loop. The problem I'm having is with Hourly. Modifying data within the scope of a for loop doesn't change the actual object, but I'm not sure how to modify temperature as I can't access the slices by index or like a regular list as I've seen in other solutions. models.py class DataPoint(models.Model): ... # Other fields temperature = models.FloatField(null=True, blank=True) def convert_f_to_c(self, temperature_f): if temperature_f is not None: return float("{0:.2f}".format((temperature_f - 32) * .5556)) return temperature_f def get_si_units(self): self.convert_f_to_c(self.temperature) class Meta: abstract = True class Currently(DataPoint): pass class Hourly(DataBlock): pass class HourlyPoint(DataPoint): hourly = models.ForeignKey( Hourly, on_delete=models.CASCADE, related_name='data' ) class Location(model.Model): ... # Other fields currently = models.ForeignKey(Currently) hourly = models.ForeignKey(Hourly) def get_si_units(self): self.currently.get_si_units() # modifies the location for data in self.hourly.data.all(): data.get_si_units() # doesn't modify the location object views.py class SomeView(APIView): def get(self, request, *args, **kwargs): ... location = Location.objects.get(latitude, longitude) location.get_si_units() return LocationSerializer(location).data -
How to properly import two top-level modules? - module has no attribute error
In the views.py file, I am importing a form to render a form. It also has a global variable defaultSelection and the get method would return the global variable. #views.py from .forms import testingForm context = ('form', testingForm) defaultSelection = 'A' def getDefaultSelection(): global defaultSelection return defaultSelection In the form.py file, I was trying to retrieve the global variable #form.py from . import views defaultSelection= views.getDefaultSelection() class testingForm(forms.Form): But I am getting a module has no attribute error importing the form in the views.py file -

Trying to deloy django without root, server cant find .fcgi file
I am trying to deploy django onto an a2hosting vps account (https://myfantasyedge.com) without root access. I followed the directions for installation here except since I wasn't allowed a global virtualenv account I used: pip install --user virtualenv and my virtual environment had to be added to ~/djangoenv instead of the path described. I couldn't find any instructions that described how to alter install to account for this so I continued on and tried my best to substitute what i thought was right eg.paths. I added these 2 files to my html_public: .htaccess AddHandler fcgid-script .fcgi AddHandler fcgid-script .fastcgi RewriteEngine on # Set up static content redirect: RewriteRule static/(.+)$ mysite/public/static/$1 # The following two lines are for FastCGI: RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ application.fcgi/$1 [QSA,L] application.fcgi #!/home/fantasy2/.local/lib/python2.7 # Set up the virtual environment: import os, sys os.environ.setdefault('PATH', '/bin:/usr/bin') os.environ['PATH'] = '/home/fantasy2/djangoenv/bin:' + os.environ['PATH'] os.environ['VIRTUAL_ENV'] = '/home/fantasy2/djangoenv/bin' os.environ['PYTHON_EGG_CACHE'] = '/home/fantasy2/djangoenv/bin' os.chdir('/home/fantasy2/public_html/mysite') # Add a custom Python path. sys.path.insert(0, "/home/fantasy2/public_html/mysite") # Set the DJANGO_SETTINGS_MODULE environment variable to the file in the # application directory with the db settings etc. os.environ['DJANGO_SETTINGS_MODULE'] = "mysite.settings" from django.core.servers.fastcgi import runfastcgi runfastcgi(method="threaded", daemonize="false") After adding these it says to check the url to see the "it worked" page … -
Django bad password exception with all auth(not sure if this is it)

{u'error_description': u'', u'error': u'params_missing'} (Podbean)
I am making a Django app to upload my .mp3 files in Podbean. I have tried uploading the file through 'terminal' and it was a success. But now I want to upload the files through my app. To achieve this I have to follow 3 steps. First I have to authorize the file through requests.post and get the result in json. Then from the json data I want to specifically get some data. I have tried the following query but an error shows up.

Django Email Backend
I'm developing a django app locally and trying to configure it to use the Amazone SES service to send emails. I've installed django-ses and added this to my settings.py: EMAIL_BACKEND = 'django_ses.SESBackend' AWS_SES_REGION_NAME = 'us-west-2' AWS_SES_REGION_ENDPOINT = 'email.us-west-2.amazonaws.com' AWS_ACCESS_KEY_ID = '...' AWS_SECRET_ACCESS_KEY = '...' Unfortunately, mail.get_connection() returns that it's still using django.core.mail.backends.console.EmailBackend; both in the shell and when the development server is running. It behaved the same when I was attempting to go the normal smtp configuration route with django.core.mail.backends.smtp.EmailBackend too... Any ideas as to why it's not making the switch? -
Django Full Text Search Not Matching Partial Words
I'm using Django Full Text search to search across multiple fields but have an issue when searching using partial strings. Lets say we have a report object with the name 'Sample Report'. vector = SearchVector('name') + SearchVector('author__username') search = SearchQuery('Sa') Report.objects.exclude(visible=False).annotate(search=vector).filter(search=search) The following QuerySet is empty but if I include the full word 'Sample' then the report will appear in the QuerySet. Is there anyway to use icontains or prefixing with django full text search? -
Django: Operational Error with html template and "no such table"

Can I use bulk_create on models with primary keys being AutoFields without making the data inconsistent?
From Django documentation of bulk_create: If the model’s primary key is an AutoField it does not retrieve and set the primary key attribute, as save() does, unless the database backend supports it (currently PostgreSQL). Well I'm not using Postgres. Am I to understand that if my model's pimary key is an AutoField then bulk_create will insert rows to the database with empty primary key column? I suppose that having in a table rows with no value for primary key is a straight way to problems, since it breaks the invariant that each row must have a primary key set and no two rows may have the same primary key, right? Can I solve this problem by manually setting the primary key like this when I know the table to be empty before the bulk_create? Person.objects.bulk_create([ Person(name='John', surname='Doe', pk=1), Person(name='Mary', surname='Sue', pk=2) ]) Will it not create problems with further insertion of objects? For example, if after the above statement I do: Person.objects.create(name='Donald', surname='Duck') Will Donald Duck's primary key be correctly set to 3? Or will it be incorrectly set to 1? Can I force the primary key counter for the new objects to be set to an arbitrary value (like, … -
why don't the django cms urls match even though they look exactly the same in the error?
So I am trying to make a simple url to make an ajax call on and I keep getting the error saying that the url does not match any of the urls in the system It looks exactly the same to me: ^en/ ^registration/ ^create-user/$ [name='create_user'] The current URL, /en/registration/create-user/, didn't match any of these . The way I am loading things is by putting this in my main urls file: url(r'^registration/', include('registration.urls')), and then in a registration app I have another urls file. urlpatterns = [ url(r'^create-user/$', ajax.create_user, name="create_user") ] To me it seems like the url /registration/create-user/ should match.What am I doing wrong? -

Unit tests fail after a Django upgrade
I am trying to bring a Django project from version 1.8 to 1.11. Pretty much everything seems to work fine except unit tests. We have a base test class inheriting from Django TestCase with a Tastypie mixin. The base class has some code in the setUp() list this class BaseApiTest(ResourceTestCaseMixin, django.test.TestCase): def setUp(self): super().setUp() self.username = "secret_user" self.password = "sekret" self.email = "secret@mail.com" self.first_name = "FirstName" self.last_name = "LastName" self.user = User.objects.create_superuser( self.username, self.username, self.password ) And the app specific tests would inherit the base test and do something like class TheAPITest(BaseApiTest): def setUp(self): super().setUp() # more setup goes here So, under Django 1.8.x this works fine. But under 1.11.x all of these give me an error on the User.objects.create_superuser() line. django.db.utils.InterfaceError: connection already closed I have been going through the release notes, but there is just too much stuff that has happened between 1.8 and 1.11. Is there something simple that I am missing? -
Django Channels: How to flush send buffer

Consider the following code: @channel_session def ws_receive(message): for a in range(10): message.reply_channel.send({'text': json.dumps({'test': '123'})}) time.sleep(1) Im receiving the respons on the client after the for-loop has completed iterations, in this example after 10 seconds. Question: Is it possible to flush the send 'buffer', meaning the message.reply_channel.send function will send immediately? -
Getting the Django-generated unique name of a file uploaded multiple times
I am using DRF backend to upload files. In my specific case I will want to get the name of the file, after it has been uploaded.

How can I use django's default test framework to test a module included in sys.path that is not a subdirectory of the django project?
I have a django (1.8) site that is structured like this: .../django_project/ ./templates/ ./manage.py ./<dir with settings,urls,etc> .../django_app_project/ ./app_name/ ./<app files> ./test_app.py To run the site, I set the environment variable PYTHONPATH=.../django_app_project/. This works perfectly when running the server, but causes problems when running the tests. Django's DiscoverRunner (django.test.runner.DiscoverRunner) does not notice .../Django_app_project/app_name/test_app.py. How can this be made to work without moving the app into the Django project? (It is outside for version control reasons) -

How should mock this get_request() method? -
TypeError: __str__() takes 0 positional arguments but 1 was given (Django)
Whenever I am going to posts/new link Django is giving '**TypeError at /posts/new/ __str__() takes 0 positional arguments but 1 was given This is the view: class CreatePost(LoginRequiredMixin, generic.CreateView): fields = ('message', 'group') model = models.Post def form_valid(self , form): self.object = form.save(commit=False) self.object.user = self.request.user self.object.save() return super().form_valid(form) This is the Post Model: class Post(models.Model): user = models.ForeignKey(User,related_name='posts') created_at = models.DateTimeField(auto_now=True) message = models.TextField() message_html = models.TextField(editable=False) group = models.ForeignKey(Group, related_name='posts', null=True, blank=True) def __str__(self): return self.message def save(self,*args, **kwargs): self.message_html = misaka.html(self.message) super.save(self,*args, **kwargs) def get_absolute_url(self, *args, **kwargs): return reverse('posts:single', kwargs={'username':self.user.username, 'pk':self.pk}) class Meta: ordering = ['-created_at'] unique_together = ['user', 'message'] And this is the post_from.html: {% extends "posts/post_base.html" %} {% load bootstrap3 %} {% block post_post %} <h4>Create a new Post</h4> <form id="postForm" action="{% url 'posts:create' %}" method="POST"> {% csrf_token %} {% bootstrap_form form %} <input type="submit" value="Post" class="btn btn-primary btn-large"> </form> {% endblock %} Whenever I am removing {% bootstrap_form form %}, I am getting the page without form. But when I have {% bootstrap_form form %}, I am getting TypeError at /posts/new/ __str__() takes 0 positional arguments but 1 was given After a lot of searching, I don't able to find where the problem is! -
Django. Refreshing part of the page with ajaxForm
I am submitting forms via django forms and I want data to refresh on submit in a certain part of the page (div) $(function () { $('#post-form').ajaxForm({ success: function (json) { console.log(json); // log the returned json to the console $('#this').append('snippet.html') console.log("success"); // another sanity check } }) }); of an html snippet <div id="this"> <tr> <th>ID</th> <th>Дата</th> <th>Цена</th> <th>Откуда</th> <th>Куда</th> <th>Водитель</th> </tr> {% for item in query_set %} <tr> <td>{{ item.id }}</td> <td>{{ item.date }}</td> <td>{{ item.price }}</td> <td>{{ item.des_from }}</td> <td>{{ item.des_to }}</td> <td>{{ item.driver }}</td> </tr> {% endfor %} </div> And here is "views" file def post(self, request): csrf_token_value = get_token(self.request) data = {} form = SchedForm(request.POST) if form.is_valid(): obj = form.save() data['result'] = 'Created!' data['object'] = { 'price': obj.price, 'driver': obj.driver_id, 'des_from': obj.des_from_id, 'des_to': obj.des_to_id, 'date': obj.date, } return JsonResponse(data) else: return JsonResponse(form.errors) The problem is I have a JsonResponse in view's return while on the INTERNET I've read that there are two solutions via render_to_response and render_to_string. But as far as I'm concerned to refresh data in forms you need render_to_string. I just don't see a way to include it in the return with JsonResponse
