Django REST Swagger: List and Retrieve functions are not detected by Swagger
I'm using django-rest-swagger version: 2.0.5 and django-rest-framework version: 3.4.6. I realiased that when I use list or retrieve functions the Swagger can not detect them as new endpoints. I have the following code in my views.py file: from rest_framework.viewsets import ViewSet class OrdersViewSet(ViewSet): lookup_field = 'uuid' def list(self, request: Request, *args, **kwargs): try: changeset = OrderSyncHelper().get_order_list_data() return Response(status=HTTP_200_OK, data=changeset) except (KeyError, ValueError) as e: return Response(status=HTTP_400_BAD_REQUEST, data=e.args) def retrieve(self, request: Request, uuid: str, *args, **kwargs): try: changeset = OrderSyncHelper().get_order_data(uuid) return Response(status=HTTP_200_OK, data=changeset) except (KeyError, ValueError) as e: return Response(status=HTTP_400_BAD_REQUEST, data=e.args) I was expecting to see in the openapi.json file the following endpoints: orders/ orders/{uuid}/ But they are not presented. Should I add something specific to these functions in order to be detected by Swagger? -

Trouble with FedEx Web Service 'Open Ship'
I'm a bit at a loss with FedEx's "Create Open Shipment" web service. It's supposed to send the shipper an email where they can print off a shipping label, or a code that they can bring into a nearby FedEx store. I successfully sent a request to FedEx, and got back a success response, but I have received no email. I attempted to use a test server, and a live server, but in either case I don't get the email. Also it should be known that I am using a Python wrapper for FedEx's web services.

Set or change the default language dynamically according to the user - Django
Is there any way to change the value of LANGUAGE_CODE variable in settings.py dynamically on clicking a button (sending a request)? I want the user to have their own "default language" set for their account. Right now the user can select their preferred language using a drop-down list, and the website gets translated perfectly, and because Django picks up the browser's language, the user need not to re-select their language after they reopen the website from the same browser. But when they open the website from a different browser, the default language is again "English" because of the LANGUAGE_CODE variable set to en-us in settings.py. So what I want to do is make each user have an option to select their desired language as default for them. I want to do this by making an another(similar) drop-down and ask user to select a language they want as "default" and hit the save button, and on saving, I want to change LANGUAGE_CODE's value to the one selected by the user (i.e change it dynamically). But I don't know how to change the value of LANGUAGE_CODE dynamically. Also, there is one more problem with this approach. Say even if I was able … -

Schema Django Rest Framework for custom action
I am using django rest framework 3.6. The problem I am having is that I have a modelviewset with a detailroute action. The detailroute action requires POST fields that are different than the corresponding model fields. When the schema is generated for the API documentation it will say that no parameters are needed. How would I go about documenting the parameters needed. I know that somehow I have to edit the schema but I am not sure the best approach to do this. -

Update another model's object after a form submit
I am attempting to update another model's object after a form submit. I would like the single object, already in existence within the Savings model, updated to reflect the most recent Entry submission. That Savings object has a pk=1.

How do I get Django to correctly parameterise sqlite query?
When I passed a wildcard into the query it was still treated as a wildcard. I can see why this error is occurring, but is there a way to get all inputs passed into the query to be treated as raw text. Also, will this mean other inputs could lead to a form with this query running in the back end being SQL injectable? -
oscarcommerce catalogue import
I have a magento2 project. I want to import product catalog in magento 2 into django oscarcommerce.

I tried to figure out how it works. But I couldn't find the source csv file to test with. Is there any module/scripts which convert data in magento2 to oscar commerce?

How do I save data to a mongo database from a formset in Django?
I'm new to this application and still familiarizing myself with the architecture. What I have is a page made of multiple forms that needs to take input and save that to multiple collections (classes, items, personnel) in a Mongo database linked by _id (item_id and personnel_id). I have the following: forms.py: class DataGenerationForm(forms.Form): number_of_items = forms.IntegerField( widget=forms.NumberInput(attrs={'class' : 'form-control'})) label = forms.CharField( widget=forms.TextInput(attrs={'class' : 'form-control'})) def save_to_mongo(self): pass #placeholder statement urls.py urlpatterns = [ url(r'^class/$', DataGenerationFormView.as_view()), ... I'm not entirely sure how to proceed from here as this is new territory for me -- specifically, I can't figure out exactly how to implement the save_to_mongo() function here. I'm at a bit of a loss on how to proceed since I'm not entirely sure I am framing the problem correctly. It seems like I'll have to process each of the formsets individually and make a connection separately -- but I've never seen that done this way. -
django formwizard save locally on form navigation
I am using Django formwizard and at the moment I save the data to the model everytime the user navigates the forms. This way the data persists between the forms. However, I was wondering if there was a way to save the data locally using javascript instead of on the server during form navigation for user experience. At the moment, my django form-wizard lies in a jquery bootstrap dialog and I perform a submit operation to save form data as follows: $("#dialog").submit(function(e) { var the_url = "/reviewrecord/" + sessionStorage.getItem("pk") + "/"; var postData = $("#review-form").serializeArray(); $.ajax( { url: the_url, type: "POST", data: postData, success: function (data, textStatus, jqXHR) { $('.modal-body').html(data); }, error: function (jqXHR, textStatus, errorThrown) { alert(errorThrown); } }); $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); e.preventDefault(); e.unbind(); //unbind. to stop multiple form submit. }); return false; } This triggers the done method in my SessionWizardView and saves the data. This method is defined as; def done(self, form_list, **kwargs): print "Saving data" if 'pk' not in self.kwargs: return redirect('reviewrecord') pk = self.kwargs['pk'] # Update the record try: instance = DummyModel.objects.get(pk=pk) for form in form_list: for field, value in form.cleaned_data.iteritems(): setattr(instance, field, … -

Unfortunately then, when I try to run python manage.py qcluster I get these error messages: (djangoq_tut) D:\Code\Python\DjangoQ_Tutorial\djangoq_demo>python manage.py qcluster Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "D:\Code\Python\DjangoQ_Tutorial\djangoq_tut\lib\site-packages\django\core\management\__init__.py", line 350, in execute_from_command_line utility.execute() File "D:\Code\Python\DjangoQ_Tutorial\djangoq_tut\lib\site-packages\django\core\management\__init__.py", line 342, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "D:\Code\Python\DjangoQ_Tutorial\djangoq_tut\lib\site-packages\django\core\management\base.py", line 348, in run_from_argv self.execute(*args, **cmd_options) File "D:\Code\Python\DjangoQ_Tutorial\djangoq_tut\lib\site-packages\django\core\management\base.py", line 399, in execute output = self.handle(*args, **options) File "D:\Code\Python\DjangoQ_Tutorial\djangoq_tut\lib\site-packages\django_q\management\commands\qcluster.py", line 22, in handle q.start() File "D:\Code\Python\DjangoQ_Tutorial\djangoq_tut\lib\site-packages\django_q\cluster.py", line 57, in start self.sentinel.start() File "c:\program files (x86)\python35-32\Lib\multiprocessing\process.py", line 105, in start self._popen = self._Popen(self) File "c:\program files (x86)\python35-32\Lib\multiprocessing\context.py", line 212, in _Popen return _default_context.get_context().Process._Popen(process_obj) File "c:\program files (x86)\python35-32\Lib\multiprocessing\context.py", line 313, in _Popen return Popen(process_obj) File "c:\program files (x86)\python35-32\Lib\multiprocessing\popen_spawn_win32.py", line 66, in __init__ reduction.dump(process_obj, to_child) File "c:\program files (x86)\python35-32\Lib\multiprocessing\reduction.py", line 59, in dump ForkingPickler(file, protocol).dump(obj) TypeError: can't pickle _thread.lock objects (djangoq_tut) D:\Code\Python\DjangoQ_Tutorial\djangoq_demo>Traceback (most recent call last): File "<string>", line 1, in <module> File "c:\program files (x86)\python35-32\Lib\multiprocessing\spawn.py", line 100, in spawn_main new_handle = steal_handle(parent_pid, pipe_handle) File "c:\program files (x86)\python35-32\Lib\multiprocessing\reduction.py", line 86, in steal_handle _winapi.DUPLICATE_SAME_ACCESS | _winapi.DUPLICATE_CLOSE_SOURCE) PermissionError: [WinError 5] Access …
