Invalid type for parameter Message
I try to use signal in django to send sns email in aws, my code is :- import boto3 from properties.models import PropertyList from django.db.models.signals import post_save, post_delete from django.dispatch import receiver @receiver(post_save, sender=PropertyList) def send_property_details(sender, instance, created, **kwargs): if created: sns = boto3.client('sns') response = sns.publish( TopicArn='arn:aws:sns:eu-west-1:238625232820:TestProperty', Message={ "default": instance.title }, MessageStructure='json', Subject='New Property Created', MessageAttributes={ 'default':{ 'DataType':'String', 'StringValue':instance.title } }, ) print(response['MessageId']) I get error as:- Invalid type for parameter Message, value: {'default': 'aws'}, type: , valid types: in AWS docs said If I want to send different messages for each transport protocol, set the value of the MessageStructure parameter to json and use a JSON object for the Message parameter.

What settings are required for Heroku to communicate between Unity and the Django server in Heroku?
I want to communicate with a Django server deployed in Heroku using the UnityWebRequest class. The nodejs server our teammates have placed in Heroku works well, but the Django server I deploy does not. Of course, the Django server's connection to the Internet browser is nice, but strangely, Unity's request issued a Can not connect to Destination Host warning. I am using Heroku for free. Do I need a setting that I do not know on Heroku's dashboard? I do not want to use Socket for communication. Of course, communication via the WWW class was useless. Does anyone have experience with me? -
Django - Unable to display an image from folder within media folder
I am trying to load an image from a folder within 'media' folder (media/tshrirts) onto template using django. Below is my settings.py STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), ] MEDIA_URL = '/media/' #MEDIA_ROOT = os.path.join(BASE_DIR,'media') MEDIA_ROOT = 'media' **I tried both the roots none of them work.

Python - Enable TLS1.2 on OSX
I have a virtualenv environment running python 3.5 Today, when I booted up my MacBook, I found myself unable to install python packages for my Django project. I get the following error: Could not fetch URL <package URL>: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:646) - skipping I gather that TLS 1.0 has been discontinued, but from what I understand, newer versions of Python should be using TLS1.2, correct? Even outside of my environment, running pip3 trips the same error. I've updated to the latest version of Sierra and have updated Xcode as well. Does anyone know how to resolve this? -

Uploaded files/chunks are disappearing
I'm trying to set up a large file upload system using resumable.js and django. The front end is all properly configured, and for the django side of things I am using django-resumable. I'm using a very basic view to handle the upload: from resumable.views import ResumableUploadView from django.conf import settings from django.core.exceptions import ImproperlyConfigured class UserFileUploadView(ResumableUploadView): @property def chunks_dir(self): chunks_dir = getattr(settings, 'MEDIA_ROOT', None) if not chunks_dir: raise ImproperlyConfigured( 'You must set settings.MEDIA_ROOT') return chunks_dir When I upload a file, it appears to upload correctly, but I can't see the chunks or the completed file in the MEDIA_ROOT directory. If I cancel the upload, the server sometimes mentions a ConnectionAbortedError with a few AttributeErrors following it, and starting a new upload ignores all uploaded chunks. If I allow the upload to complete, I can't upload the file again until the page refreshes. In looking over the django-resumable code, I understand how it's supposed to function and can't see any reason why it shouldn't. Is there any way to figure out if the chunks are uploading, and where they're going if they are? -

Django URL Redirects And Changing URL Structure
I'm trying to get some information before i change the URL structure of my website. I want to better organize the overall folder system for my 'deals website. currently my urls look like this for a specific deal : deals/discount-bike-at-walmart-99 for a specific category: deals/category/apparel for a specific retailer: deals/retailer-deals/walmart i feel like maybe these folders are a bit too long if i do want to change them, does django allready handle the redirects or is there something I need to do handle this? my site is allready indexed by google, so i'm trying to avoid an issue where I'm creating duplicated content -
django sessionid and csrrftoken and vue axios
I have a question about using vue axios frontend and Django backend in cors- domain environment. My cookie can use set-Cookie sessionid and csrftoken but frontend can't get these parameters to save to my document.

But I won't use this csrftoken to backend verify in other POST AJAX, how can I resolve it to verify?

Django - Get Value Only from queryset
When the docs discuss values() and values_list(), or any query for that matter, they always require that you know what you are looking for, i.e., >>> Entry.objects.values_list('headline', flat=True).get(pk=1) 'First entry' What about the situation where you need a value from a specific field, whether on this model or a foreign key, but you don't know the pk or the value in the specified field, and you don't care, you just need whatever is there. How do you query for it? Alternatively, if I use this example from the docs: >>> Entry.objects.values_list('id', flat=True).order_by('id') <QuerySet [1, 2, 3, ...]> Could I add slice notation to the end of the query? But even then, I might not know in advance which slice I need. In other words, how to dynamically get a value from a specified field without knowing in advance what it or its pk is? Thx. -

Django: How to get parent url when iframe is loaded
I am using @xframe_options_exempt in my django view so that I can load this view from an iframe. I want to do some if url = xxx filtering on the page but I need to get the Parent URL of the iframe. For example the parent url is "http://mycoolsite.com" which loads "http://mycooldata.com/data" in an iframe. If i do something like request.get_absolute_uri, it will return "http://mycooldata.com/data" (the url that the iframe is) when i want it to return parent url of "http://mycoolsite.com" instead. Any ideas on how to get that to happen? Using python 3.6 and django 1.11. Thanks, jAC -
Django ValidationError formating in a For Loop
I've written a series of RegexValidator definitions that I call on django model inputs. Here is an example: def fein_validator(value): err = None for validator in FEIN_VALIDATOR: try: validator(value) return value except ValidationError as exc: err = exc raise err For reference the FEIN_VALIDATOR for this method is below. Note that in this example there is only a single item, I have other validators that have multiple items (hence the for loop): FEIN_VALIDATOR = [ RegexValidator(r'^\d{2}-\d{7}$') ] The method works perfectly and throws an error when it's supposed to. But, the error it throws is Enter a valid value. and I would like to customize the return to be more specific. I've tried versions of this and this. But these all assume that there is only one pass. I'm trying to run through a series of validators using a for loop. Question 1: does the method construction I'm using work for this - or should there be a separate method for each validation? [whereby I can add custom messaging.] Question 2: if this does work, how do I change the error message raised to a custom message? -

Batch requests Gmail API
I have a python project (Django) connected to Gmail API. I need to get all the messages that the user has and save 'metadata' of every message. If I do that with a loop and make one request for message[i] - this will be slow. Well, now I have this spaghetti code with these while loops. (What I do else is I store "From" and "To" addresses from metadata of every message and count who sent you messages the most). This code is slow and hard-readable, probably because of those one-by-one requests: import operator from googleapiclient import errors from .quickstart import service def getTop(n): try: label = '' if n == 1: label_ids = "INBOX" label = "From" else: label_ids = "SENT" label = "To" user_id = "me" topers = service.users().labels().get(userId=user_id, id=label_ids).execute() count = topers['messagesTotal'] topers = service.users().messages().list(userId=user_id, labelIds=label_ids).execute() tmp = [] st = [] if 'messages' in topers: tmp.extend(topers['messages']) l = len(tmp) for i in range(0, l): idshka = tmp[i]['id'] mdata = service.users().messages().get(id=idshka, userId=user_id, format='metadata', metadataHeaders=[label]).execute() head = mdata['payload']['headers'] obval = head[0]['value'] # algo/////////////////////// t = str(obval) t = t.split('<', 1)[-1] t = t.replace('>', "") st.append(t) while 'nextPageToken' in topers: tmp = [] page_token = topers['nextPageToken'] length = len(page_token) … -

Get non-deleted forms from Django formset
When I use a formset that's both can_order and can_delete I'm able to get all the deleted forms with .deleted_forms and all the non-deleted forms (in order) with .ordered_forms. If I use a formset that doesn't use can_order I no longer have access to .ordered_forms (it throws an exception). Is there an easy way to get the list of forms that are not deleted? The closest I can find is manually creating it with: [form for form in formset.forms if not formset._should_delete_form(form)] However, that's using a "hidden" method and it seems odd there's not something already built-in. -
