What's the issue this log is indicating?
I have a Python/Django/Wagtail project running in Heroku. We just pushed a big change, but then we get a Application Error, supposedly an issue somewhere in the code. The app works fine locally. This issue happens when pushing Heroku. So I check the logs, it is not saying exactly what the issue is, just indicating a list of files. It starts like this: from wagtail.wagtailadmin.edit_handlers import ( app_config = apps.get_containing_app_config(module) worker.init_process() return util.import_app(self.app_uri) from imports import * The logs are actually longer, but I think that's the important part. The file and line it lists looks partially like this: from wagtail.wagtailadmin.edit_handlers import ( FieldPanel, FieldRowPanel, InlinePanel, MultiFieldPanel, PageChooserPanel, StreamFieldPanel ) So, what is Heroku complaining about? Why is it so obscure about the issue here? Dependencies seem not to be the problem, I already tested that. -
JSON Material UI Select DropDown
I cannot get a material ui Drop down to populate with JSON Data. Can someone see what I'm doing wrong? Here is the code that has the JSON and the code itself. ` const json = { ResponseMetadata: { RequestId: "1B29B45E145594A7", HostId: "fNB6fQZ8LQrK53j9lIOMSKy49mA8xrAMiwVh05/fKcBB5/gjYF6qUdxLFw4/zR5mRNHg2ge6t3w=", HTTPStatusCode: 200, HTTPHeaders: { "x-amz-id-2": "fNB6fQZ8LQrK53j9lIOMSKy49mA8xrAMiwVh05/fKcBB5/gjYF6qUdxLFw4/zR5mRNHg2ge6t3w=", "x-amz-request-id": "1B29B45E145594A7", date: "Sun, 13 May 2018 20:36:02 GMT", "content-type": "application/xml", "transfer-encoding": "chunked", server: "AmazonS3" }, RetryAttempts: 0 }, Buckets: [ { Name: "eladft-1-653237860766", CreationDate: "2014-09-01T16:58:41Z" }, { Name: "elasticdf37860766", CreationDate: "2015-10-06T00:24:57Z" }, { Name: "elasticdf0766", CreationDate: "2015-10-02T17:37:19Z" } ], Owner: { DisplayName: "dfdf", ID: "b4bf8bde7571756284e067071dfe442c7b014a09f012a1179" } }; ` <form className={classes.root} autoComplete="off"> <FormControl className={classes.formControl}> <InputLabel htmlFor="bucketName-simple">Buckets</InputLabel> <Select native="true" value={this.state.json.Buckets.Name} onChange={this.handleChange} inputProps={{ name: "v_bucketName", id: "age-simple" }} > {this.state.json.Buckets.map((Buckets, i) => ( <MenuItem native="true" key={i} value={Buckets.Name}> {Buckets.Name} </MenuItem> ))} )} </Select> </FormControl> </form> ); } } The data from AWS S3.

How to mock super method in Django from multiple level deep mixin
I am working on some simple Unit Tests in Django==1.11 and python==2.7.12. All of the similar tests the execution time of the test is around 0.0040 seconds, for example the custom suspend action which is included with test at the bottom of the post. All of the used classes, forms, called functions are mocked in all tests. Though, the test of the unsuspend action consumes 10 times as much time to execute with an average of 0.0400 seconds which I do not understand why, since it is even a simpler then the suspend action. # The custom unsuspend DRF action being tested @action(methods=['get'], detail=True, permission_classes=[OrganizationBasePermissions]) def unsuspend(self, request, uuid): organization = self.get_object() start = datetime.datetime.now() mc_organization.services.organization.unsuspend(organization=organization) end = datetime.datetime.now() print('service call duration:', end - start) # ('service call duration:', datetime.timedelta(0, 0, 143)) serializer = self.get_serializer(instance=organization) return Response(data=serializer.data, status=status.HTTP_200_OK) # The unittest of the unsuspend action above @mock.patch('mc_organization.api.viewsets.organization.Response') @mock.patch('mc_organization.api.viewsets.organization.ModelViewSet.get_serializer') @mock.patch('mc_organization.api.viewsets.organization.'

Issue with Django, Apache, mod_wsgi, and caching CSS files
Alright, so I've got a setup which consists of Apache 2.4, Django 2.0.5, Python3.5, mod_wsgi, all running on Debian. When I go to edit a CSS file on my production server, the file doesn't update until I entirely reboot the server it's on. As you can imagine this is tedious and time consuming, so I'd like to find a solution.

Best way to set cookies in a Django view?
I'm working on modifying a Django view that is similar to the following: class ListBase(DashboardAccessMixin, OrderingMixin, FilterMixin, SearchMixin): def get(self, request, *args, **kwargs): if should_delete_filter_cookie(request, path=reverse('dashboard:families')): request.COOKIES.pop('filters', None) self.query_dict = query_dict_from_params_or_cookies(request) return super().get(request, *args, **kwargs) def render_to_response(self, context, **response_kwargs): response = super().render_to_response(context, **response_kwargs) path = reverse('dashboard:families') if should_delete_filter_cookie(self.request, path=path): response.delete_cookie('filters', path=path) elif list(self.request.GET.items()): response.set_cookie('filters', self.request.GET.urlencode(), path=path) return response where the auxiliary functions should_delete_filter_cookie and query_dict_from_params_or_cookies are defined as def query_dict_from_params_or_cookies(request): query_dict = request.GET cookie_filters = request.COOKIES.get('filters') if cookie_filters and not list(query_dict.items()): query_dict = QueryDict(cookie_filters) return query_dict def should_delete_filter_cookie(request, path): referer_path = urlparse(request.META.get('HTTP_REFERER')).path if referer_path and path not in referer_path: return True else: return False The view has a filter_form and a search_form (through the corresponding mixins) which are bound with self.query_dict. Further, we follow the naming convention that the URLs for the UpdateView and CreateView are simply 'extensions' of that for the ListView's URL: for example, the former is /dashboard/families and the latter is simply dashboard/families/1 (but not dashboard/family/1). The ListView is now such that when you return to it from an UpdateView, it persists the filters that were previously applied by getting the self.query_dict from the cookies. What I'm wondering is why should_delete_filter_cookie is invoked twice, in the get() … -
How to use regular expression to match a string include transverse line?
I want to use dynamic url in Django to match my dynamic href in template, which is assembled from addresses, such as below: ../details/0-TIFFANY-CRES ../details/1-Airport-PKY I am a layman of regular expression, the current url I want to match is : path('details/[-\w]', details), it didn't work(of course). In addition, I want to use the address in the urls in my views, how can I convert this address to my new views function? How can I match the urls? If there is any unclear parts, please tell me and I will try to explain more. -
POST to more than one view with two buttons?
I'm a beginner developer and i'm struggling to get my form(s) to POST partially the same information to two different locations. I'm looking to POST the user information in this first form to an additional view called update and then POST the user information and the remaining information to another view called Submitted. My second submit button is working correctly, it's the first input button that i'm having trouble with. It's just posting to the submitted view instead of update. I have two different buttons in my form. The one with only the user information is defined as: <button type="input" class="btn btn-primary"> <span class="glyphicon glyphicon-edit"></span> Update </button> Then second for the submit is: <button class="btn btn-primary my_select" type="submit">Request Access</button> My entire code set is the following: {% extends 'base.html' %} {% load static %} {% block head %} <title> Profile </title> {% endblock %} {% block content %} <form action = "{% url 'submitted' %}" form method = "POST"> <form action = "{% url 'update' %}" form method = "POST"> {% csrf_token %} <div class="well"> <h4 style="margin-top: 0"><strong> User Details </strong></h4> <div class="row"> <div class="form-group col-md-4"> <label/> 3-4 User ID <input class="form-control" type="text" name = "userpost" value= "{{employee.employeentname}}" readonly> </div> … -
How to handle DenyConnection error raised by Django Channels in frontend
Is there a way I can deny a websocket connection in Django Channels and let the frontend know why the connection was refused. The channels documentation mention the channels.exceptions.DenyConnection error. When I raise it, I get a 1006 close event in the frontend, which is an abnormal closure and could be raised in other circumstances, I guess. I am looking for a way to indicate that the connection was refused. -
Creating a "simple" dictionary in a Django model?
Apologies for the vague title, but I'm really having trouble describing this concept. Basically what I want is to import some json data I've created into some Django models. My data looks like this, basically: [ { name: "Bingfordshire" results: { 'LIB' : 23, 'PC': 25 }, more dictionaries here.... }, more objects here.... ] I've setup a model for the the outer object, but I'm struggling with how to represent those interior dictionaries. My first idea was to just use fields like this: class Riding: lib_result = models.DecimalField() pc_result = models.DecimalField() But I have three such dictionaries and about 4 entries for each, making this a lot of typing, and a massive pain to change if I ever want to add a new entry or something. My next idea was to use database relations: class PartyResult: party = models.CharField() result = models.DecimalField() class Riding: results = models.ManyToManyField(PartyResult) But this adds some complexity to using it, and makes the admin site a lot less usable, and I don't want to have to do a bunch of database queries just to read one Riding. Right now, I've realized I can use a ForeignKey in the PartyResult that leads to the riding, … -
How to return custom JSON from model?
I have a model with multiple fields but I only want to expose some or a combination of them. For example the model has opening_time=12:00 and closing_time=18:00 and I want to return the field opening_hours=[12:00, 18:00] in the JSON. This is just an example, but I have also some other fields to combine into one in the return JSON. How can I do this? Is there a way to modify my ModelSerializer? -

Can Django ORM join on something other than pk?
Django writes a query containing this automatically: LEFT OUTER JOIN "object" T4 ON ("start_table"."object_type_2_id" = T4."id") LEFT OUTER JOIN "destination_table" ON (T4."id" = "destination_table"."object_id") Is there a way to have Django make this more efficient by writing this instead?: JOIN destination_table ON destination_table.object_id = start_table.object_type_2_id Some context to keep in mind; the start_table has several foreign key fields that all refer to the same object table, but for different reasons, which is why I've given object_type_2_id as the column name. -

Django 1.11.7 - Django Compressor - argument 5: <class 'TypeError'>: expected LP_OVERLAPPED instance instead of pointer to OVERLAPPED

Django template display different models fields

I have just started integrating Django with Scrapy. Upon receiving the variable(that is Website url) on the Django side, I want to pass it to the scrapy part so as to crawl it. This is the code snippet I wrote on the backend. def post(self, request, format=None): ... serializer = self.serializer_class(data=data) if serializer.is_valid(): site = serializer.create(data) domain = urlparse(site.url).netloc site_id = site.id settings = { 'unique_id': unique_id, 'USER_AGENT': 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' } task = scrapyd.schedule('default', 'icrawler', settings=settings, url=url, domain=domain) task = { 'task_id': task, 'unique_id': target_id, 'status': 'started' } resp = { 'task': task, 'data': serializer.data, 'status': status.HTTP_201_CREATED } return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) I have created spider on the Django project called icrawler.py. class IcrawlerSpider(CrawlSpider): name = 'icrawler' allowed_domains = ['https://google.com'] start_urls = ['http://https://google.com/'] rules = ( Rule(LinkExtractor(allow=r'Items/'), callback='parse_item', follow=True), ) def parse_item(self, response): i = {} return i As you can see, there is allowed_domains = ['https://google.com'] and start_urls = ['http://https://google.com/'] in the spider. But I want to replace it with variable passed from Django and start running crawler, upon receiving the variable on the django side. I am not sure how I can implement it. -
Return variables to web server from PayPal Express Checkout Client REST API
I am using PayPal Express Checkout Client sided REST API javascript and Django 2.0.x/Python views for an ecommerce site. I have been able to implement Express Checkout and have the customer redirected to a success page on my server through the onAuthorize function. I need to access the paypal old IPN style listener variables or equivalent ... custom, mc_fee, email, first_name, last_name from paypal. I have no idea how to do this with the new REST API. Is this processed through a webhook and if so how? Example code? I just need the above variables returned back to my server preferably in my views.py checkout_complete function. Thanks mmbella
