django redirects on posting form using ajax
I'm trying to understand what's actually going on. I have this CreateView based class which I'm using to add new Operation: class OperationCreate(CreateView): model = Operation form_class = OperationForm success_url = reverse_lazy('manage_operations') def form_valid(self, form): (...) form.save() return JsonResponse({'result': 'success'}) def form_invalid(self, form): form.save() return JsonResponse({'result': 'error'}) After getting a form and posting it using ajax I can see following calls logged: [18/Feb/2018 22:52:54] "GET /expenses/new_operation/ HTTP/1.1" 200 1135 [18/Feb/2018 22:53:04] "POST /expenses/new_operation/ HTTP/1.1" 200 21 [18/Feb/2018 22:53:04] "GET /expenses/manage_operations/?csrfmiddlewaretoken=okXK8OwPJ9BJGQeMvSW3Y5koSeTEIXyQDBOAroI1OU8tD7GPxQxZQ37IdhdkhiKe&account=1&type=-1&category=1&date=2001-01-01&amount=2001 HTTP/1.1" 200 3842 I don't understand where did the last one came from. I know I have specified success_url which is a legacy code after previous implementation but it's not used anymore since I have redefined from_valid method. Also I don't get why this last request contains all parameters that I have posted before. Could you please explain it to me? Here is my ajax post method: function postForm(url, form_selector) { var form = $(form_selector); var csrf_token = $('input[name="csrfmiddlewaretoken"]').attr('value') form.submit(function () { $.ajax({ headers: { 'X-CSRFToken': csrf_token }, type: 'POST', url: url, data: form.serialize() }); }); }; -

how to retrieve specific card without using card id? stripe, django
I know we can use stripe customer id to retrieve list of cards attached to the customer id. Also, I know we can retrieve ONE specific card with the card's id....But what if I do not want to use the card id to retrieve the card. Instead I want to use exp month, year, last4. Is this possible? I thought of all_cards = stripe.Customer.retrieve(cus_id).sources.all(object=CARD) the_card = all_cards.all( exp_month=data.get(EXP_MONTH), exp_year=data.get(EXP_YEAR), last4=data.get(LAST_4) ) but it says no such parameters such as exp_month I thought of doing it in a way to loop through all the card and match the parameters which myself believes would be a bad idea if there is a better one. Does anyone have a better idea or suggestions? Thanks in advance for any advise -
How do I make a password from one `input` match another as I type?
I have this at the top of my HTML file: <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script> <script type="text/javascript"> var app= angular.module("app",[]); app.config(function($interpolateProvider){ $interpolateProvider.startSymbol("[[["); $interpolateProvider.endSymbol("]]]"); }); app.controller("MainCtrl",function($scope){ $scope.name= "World"; }) </script> I have two input elements. <input id="id_password1" name="password1" ng-model="pw" placeholder="Password" type="password" required=""> and <input id="id_password2" name="password2" ng-model="pw" placeholder="Confirm password" type="password" required=""> As I type my password into the first input, I'd like to fill the second with what I'm typing in the first.

Ansible-playbook says file exists, and than says it doesn't exist
I am trying to debug my ansible-playbook, and figure out why an RSA key I copy onto a Docker Image fails to be authenticated when cloning a git repository onto that Docker Image. The first thing I wanted to look at is if the RSA key file I moved even exists in the Docker Image my playbook is creating. I run a couple tasks, one to see if the file exists, and than another than displays the RSA key to me. The first task that sees whether the file exists saves that result to a variable, and in that variable I can see that the file does in fact exist. When I try to print the contents of that file though, I get an error message saying that file path doesn't exist.

use django template with dash application
I have set-up a dash application that works well with my django website, but I would like to have the dash application on a page that has a template. The setup I have is the usual one, that is : views.py def dispatcher(request): ''' Main function @param request: Request object ''' params = { 'data': request.body, 'method': request.method, 'content_type': request.content_type } with server.test_request_context(request.path, **params): server.preprocess_request() try: response = server.full_dispatch_request() except Exception as e: response = server.make_response(server.handle_exception(e)) return response.get_data() @login_required def dash_index(request, **kwarg): return HttpResponse(dispatcher(request)) @csrf_exempt def dash_ajax(request): return HttpResponse(dispatcher(request), content_type='application/json') and urls.py urlpatterns = [ re_path('^_dash-', views.dash_ajax), re_path('^', views.dash_index), ] The above code works fine. Now I've tried the following for embedding the page (view dash_index) within a template (called dashboard template). The template is not for formatting the app itself, but for elements that will be "around" the app, such as navbar, footer, menu etc. Try n°1 @login_required def dash_index(request, **kwarg): template_name = "dashboard_template.html" return HttpResponse(dispatcher(request),template_name) doesn't yield error, but doesn't display template. try n°2 : @login_required def dash_index(request, **kwarg): template = loader.get_template("dashboard_template.html") return HttpResponse(template.render(dispatcher(request))) I get the following error from the urls.py file AttributeError: module 'app_name.views' has no attribute 'dash_index' Try n°3 : @login_required def dash_index(request, **kwarg): return … -
Converting function based view to class based view to return JSON Response
I have a function based view which works fine with Bootstrap Modal dialog and returns the JSON Response. I am trying to implement this with CreateView but couldn't make it to work. Function Based View which works fine :- def task_create(request): form = CreateTaskForm(initial={'owner' : request.user, 'assignee' : request.user}) context = {'form': form} html_form = render_to_string('tasks/task_create_ajax.html', context, request=request) return JsonResponse({'html_form': html_form}) Attempt for Class Based View :- class CreateTaskView(LoginRequiredMixin, CreateView): form_class = CreateTaskForm def get_template_names(self): if self.request.is_ajax(): return ['tasks/task_create_ajax.html'] else: return ['tasks/createtask.html'] def get_form_kwargs(self): kwargs = super(CreateTaskView, self).get_form_kwargs() kwargs.update({'initial': {'owner' : self.request.user, 'assignee' : self.request.user}}) return kwargs def form_invalid(self, form): response = super(CreateTaskView,self).form_invalid(form) if self.request.is_ajax(): return JsonResponse(form.errors, status=400) else: return response def form_valid(self, form): response = super(CreateTaskView, self).form_valid(form) if self.request.is_ajax(): print(form.cleaned_data) data = { 'message': "Successfully submitted form data." } return JsonResponse(data) else: return response Problem :- In function based view, the html form is passed via variable html_form which I can view/debug in browser using console.dump command.

Transfer form together with other data using one AJAX post. Django
Very simple task. It is necessary to transfer data from the form together with other data using AJAX POST. The problem is how to extract this data later from the form, because they represent a whole line. $(function() { $('#myform').submit(function(event) { event.preventDefault(); var form=$('#myform').serialize(); var data={}; data['form']=form; data['csrfmiddlewaretoken']='{{ csrf_token }}'; data['other_data']='other_data'; $.ajax({ type: 'POST', url: '/myajaxformview', dataType: 'json', data: data, success: function (data, textStatus) { $('#output2').html(JSON.stringify(data)); }, error: function(xhr, status, e) { alert(status, e); } }); }); }); def myajaxformview(request): if request.method == 'POST': if request.is_ajax(): data = request.POST print(data) #<QueryDict: {'form': ['csrfmiddlewaretoken=VtBJ03YJZsEocJ5sxl9RqATdu38QBPgu4yPAC64JlpjOzILlF1fOQj54TotABHx9&field1=1&field2=2'], 'csrfmiddlewaretoken': ['VtBJ03YJZsEocJ5sxl9RqATdu38QBPgu4yPAC64JlpjOzILlF1fOQj54TotABHx9'], 'other_data': ['other_data']}> form=data.get('form') #csrfmiddlewaretoken=VtBJ03YJZsEocJ5sxl9RqATdu38QBPgu4yPAC64JlpjOzILlF1fOQj54TotABHx9&field1=1&field2=2 print(form) return HttpResponse(json.dumps(data)) return render(request, 'foo.html') -
Saving Django Media files on File System in Production
I am building a Django application where I have to serve some media files on server. Due to some limitations, I cannot use separate media file storage like S3 or Azure etc. What I actually do is that I need to generate an audio file on the basis of data provided by user and then play that file on browser. I delete that file after playing it. This is a research based project with no user based data and also data will be very small. Therefor I want to store media file on same server. When I run my application with DEBUG=True, data is uploaded on server and I can also access it in my web page. But when when I set DEBUG=False, I cannot access my media files stored in same server. I know the problem is that I need to deploy my media file to a separate server in production environment. But as I said, I cannot use a separate media file storage. I know that In production environment, I need to use server like Nginx and Apache when I will set path of my media file storage in nginx/apache settings and it will work. But the problem … -
Sending messages to groups in Django Channels 2
I am completely stuck in that I cannot get group messaging to work with Channels 2! I have followed all tutorials and docs that I could find, but alas I haven't found what the issue seems to be yet. What I am trying to do right now is to have one specific URL that when visited should broadcast a simple message to a group named "events". First things first, here are the relevant and current settings that I employ in Django: CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { 'hosts': [('localhost', 6379)], }, } } ASGI_APPLICATION = 'backend.routing.application' INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'corsheaders', 'channels', 'channels_redis', 'backend.api' ] Next, here is my EventConsumer, extending the JsonWebsocketConsumer in a very basic way. All this does is echo back when receiving a message, which works! So, the simple send_json response arrives as it should, it is ONLY group broadcasting that does not work. class EventConsumer(JsonWebsocketConsumer): groups = ["events"] def connect(self): self.accept() def disconnect(self, close_code): print("Closed websocket with code: ", close_code) self.close() def receive_json(self, content, **kwargs): print("Received event: {}\nFrom: {}\nGroups: {}".format(content, self.channel_layer, self.groups)) self.send_json(content) def event_notification(self, event): self.send_json( { 'type': 'test', 'content': event } ) And here … -
Ansible-Playbook debug task skipping without reason
I am running an Ansible playbook to create a docker container with a Django application. I add an RSA key to the container, create directories, and try to clone the Django repository into the container. I get an authentication error, so I'm trying to debug the issue, first off seeing if the RSA key exists. When I add a debug task however, and run the playbook, it just says 'skipped', and doesn't offer any message. I'm new to Ansible, and read the documentation, but couldn't find a reason why.

Django m2m field doesn't assign to parent object in view
I've read the Django 1.11 docs on this topic and countless questions here on SO. I'm sure I'm missing something simple, but I cannot see why my problem is occurring and have fruitlessly tried endless variations to solve, so I submit it to wiser minds for consideration. (I will post the relevant code below, wherein I believe the problem lies. And will post more if necessary, but I don't want to drown this post in code in advance if it doesn't contribute...) I am implementing a tagging system for my project. I've tried the various plug-in solutions (taggit, tagulous, etc) and each for their own reason doesn't work the way I would like or doesn't play well with other parts of my project. The idea is to have a Select2 tagging field allow users to select from existing tags or create new. Existing tags can be added or removed without problem. My difficulty is in the dynamic generation and assignment of new tags. Select2 helpfully renders the manually-entered tags in the DOM differently than those picked from the database. So upon clicking submit, I have javascript collect the new tags and string them together in the value of a hidden … -

Load JSON file's content to Heroku's environment variable
I am using Google Speech API in my Django web-app. I have set up a service account for it and am able to make API calls locally. I have pointed the local GOOGLE_APPLICATION_CREDENTIALS environment variable to the service account's json file which contains all the credentials. This is the snapshot of my Service Account's json file: I have tried setting heroku's GOOGLE_APPLICATION_CREDENTIALS environment variable by running $ heroku config:set GOOGLE_APPLICATION_CREDENTIALS="$(< Speech-Api-Proj.json)" $ heroku config GOOGLE_APPLICATION_CREDENTIALS: { ^^ It gets terminated at the first occurrence of " in the json file which is immediately after { and $ heroku config:set GOOGLE_APPLICATION_CREDENTIALS='$(< myProjCreds.json)' $ heroku config GOOGLE_APPLICATION_CREDENTIALS: $(< Speech-Api-Proj.json) ^^ The command gets saved into the environment variable I tried setting heroku's GOOGLE_APPLICATION_CREDENTIALS env variable to the content of service account's json file but it didn't work (because apparently the this variable's value needs to be an absolute path to the json file) . I found a method which authorizes a developer account without loading json accout rather using GOOGLE_ACCOUNT_TYPE, GOOGLE_CLIENT_EMAIL and GOOGLE_PRIVATE_KEY.
