How to import and use a modified npm library packages dynamically
I am using a sigmajs library for creating node based graph visualisations. But the library package had a few bugs, so I modified a few files in the source code of the library and fixed them. I have hosted my graphs on django server, and whenever I host it, the sigma package in the package.json gets loaded dynamically each time. The static library files on my machine which I had modified and fixed bugs don't get loaded. So,I get the same old package and not the modified one. How do I access the modified library package dynamically when I host the server. -
Django - passing an object to a view through template
Is there any way to pass an object to a template and through the template pass it back to another view? Is there any technique which could do that? Reason: From my django application (MYAPP) I'm using a 3rd party django application (3APP, also maintained by me). 3APP would like to use MYAPP's Object, but I've no idea how can I pass it in this construction: MYAPP's view (MV1) is calling the 3APP's view (3V1) method, which renders the template. The template has an ajax call to another 3APPS's view (3V2) function, and this one would like to use the MYAPP's Object. (During the first pass [MV1 calls 3V1 method] it's not a problem of course, it just simply passes it through an argument, but the problem is to pass it from 3V1 to 3V2, because 3V1 renders the template, and from there an ajax call calls the 3V2) Is there any way to do this? Either pass the object to the template and from there back to the 3APP's view, or any other way? Even if there's a solution, I know it won't be too djangonic... . -

python package that connect social accounts per object - django
The default behaviour of python-social-auth and other social auth package is that it bind user with a social accounts, but how can u achieve social auth per object. Here is my case. I am userX, in my django app i have a model named Company, userX managed multiple companies, and each company have their own twitter and other social accounts. So userX will add each company twitter account but after verification from twitter. Is there a way i can modify python-social-auth or all-auth package to achieve this or any other python package you can recommend. I don't want to put CharField and let user fill in the social url manually. -
In django, is it possible to have a foreign key defined to some superclass, but having returned the subclass when queried?
Assuming I have the following models: class SomeSuperClass(models.Model): ... class SomeSubClassA(SomeSuperClass) ... class SomeSubClassB(SomeSuperClass) ... class SomeConnector(models.Model): reference = models.ForeignKey(SomeSuperClass, on_delete=models.CASCADE) ... Now what I would want to have is somehow when iterating over objects of SomeConnector I always want to have right away objects of the respective subclasses, not of the superclasses. E.g. for sc in SomeConnector.objects.all(): # somehow get the correct subclass of this `reference` field here, # assuming it to be callable under sc.reference_correct_subclass: print(sc.reference_correct_subclass.__class__.__name__) could produce for example: 'SomeSubClassA' 'SomeSubClassB' 'SomeSubClassA' 'SomeSubClassA' But never should an object of the superclass be used. I know of django-model-utils and I could do something similiar by querying directly on the superclass, like this: SomeSuperClass.objects_inheritance.select_subclasses() where objects_inheritance is the InheritanceManager attached to SomeSuperClass. However I could not figure out yet how to reproduce this when the superclass is used as foreign key in another class which I want to use for querying. -

Throttle a detail view in django rest framework
I have a custom throttle: from rest_framework.throttling import UserRateThrottle class OncePerDayUserThrottle(UserRateThrottle): rate = '1/day' I use this throttle in a class api view as such: class PostHitCount(APIView): throttle_classes = [OncePerDayUserThrottle] def post(self, request, hitcount_pk, format=None): # my post method The url corresponding to this view is path('add-hitcount/<int:hitcount_pk>/', PostHitCount.as_view()) If i access this view for the first time via url add-count/1/, i am permitted. If i later post to the same url, i am not permitted (which is ok!). Now if i post to the url add-count/2/, the request is rejected since the user already accessed that view! How can i permit requests with another detail url? Also, is it possible to set the throttle rate to say 1/year or even 1/lifetime ? How ? -

Using Django "sites" framework to handle subdomains?
I am developing a language-based web application using Django. I would like to separate content using language subdomains (similar to Wikipedia, Quora, and other multilingual websites). For instance, if my website were example.com, I would like to have en.example.com for the English version of my website, es.example.com for the Spanish version of my website, and so on and so forth. I came across different Django third-party libraries that could help with subdomains but I was considering using the "sites" framework from Django itself. However, its documentation is not very explicit about subdomains but rather just talks about "websites" and it's not clear whether the framework would be suitable for my purpose. So, my question is: is the Django "sites" framework a good option for handling subdomain in a fashion similar to the one described above? -
Django FileField to upload html and send it via Email

But I have a lot of problems with the encode.  , € ... These are some of the characters i'm getting. I tried a lot of things, my actual code: template2 = default_storage.open(grupo.email.correo.path, 'r') template = template2.read() template = unidecode(template) template = Template(template) html = template.render(Context({})) email = EmailMessage( subject, html, to=[to_email] ) email.content_subtype = 'HTML' email.send(fail_silently=False) The variable grupo.email.correo is the FileField. The result: As you see, in the right of each number should be €. I tried a lot of combinations, and I get a lot of other characters, but I can't get a good decoded string, anyone knows more about this? -
