Translation Django doesn't work in template and view
I am bulding an app in django, writing all interface messages in english to after translate them to other language. My first attempt is using the spanish as language target. I have been reading other questions, but I have not had success with translation in view and template. Some questions are: Localization doesn't work Django internationalization doesn't work in my project Django translations does not work Many others In the most of them, the problem is LOCAL_PATHS setting is bad set.

How can I preserve the python '%' character when adding to a string that will be run as html?
Here is some possibly important background info: I am parsing .js paths server-side in python, adding them to the context object. My goal is to reflectively load js packages based on the url endpoint used by the client. @api_view(["GET"]) def home(request, path="tutorial"): return render(request, "template.html", context={ "path" : "{% static '"+ path +".js' %}" }) The issue I've run into is that the '%' character does not convert correctly, as you can see from the server log: [23/Apr/2022 11:05:40] "GET /%7B/%%20static%20'tutorial.js'%20/%%7D HTTP/1.1" 404 2574 I know that '%' is used by python for string manipulation and therefore is added to strings as a multi-char code, but what I can't figure out is how to add a literal %. I've tried '/%', r'', and b'' variations, .encode() too, but none of them change the output. Here is what is being run client side: <script type="text/javascript" src="{{path}}"></script> I've tested everything else, and it all works perfectly. I just can't get python to send html friendly '%'s! -

Django social-auth-app-django error after social login completed
AttributeError at /social-auth/complete/github/ 'NoneType' object has no attribute 'provider' Other solutions on this site did not solve the problem. Sorry if you see this as a dup. copied from reddit: Hello! Hope everybody is doing well. As the title suggest I keep getting this error every time I try to use the social login on my site. This is for a school and we are using github for the authorization. What I believe is happening is, the user social auth data is being sent somewhere else instead of the user social auth database. The reason I think this is because after github auths my account,and crashes, I can see it grabbed my user name and my email from github correctly in the database, I can see it in my admin. However, The user social auth remains empty.I'm pretty confident that there's a problem with my urlpatterns redirecting data into the damn sun instead of the user social auths database. Again I've got no idea how to fix this. I've been at it for about two weeks now and made no progress into solving this problem, Things I've tried: Social_auth_pipeline, dosen't work using django_allauth crashes the site I've changed my settings … -
login with existing users
I am doing a project in Django where I need to log in through existing users on another web page. For this I have a link to consume the web service and to be able to consume it I enter some parameters, among these is the user login (username) and the password, when the web service is consumed (I use the suds library to consume it), It gives me certain user data such as user, profile, name and status. I tried to search how to do this and I found that I can use the request.META['REMOTE_USER'] but I still don't understand how to implement it, is there an example? -

Django crispy-forms bug: Multiple Image input doesn't show different file names
I have a crispy form with an image input field that accepts multiple images: images = forms.ImageField(widget=forms.FileInput(attrs={'class': 'form-control', 'multiple': True}), required=False) The form works perfectly fine and the images are uploaded and can be processed in the backend. However, there is a weird frontend bug: Usually when you select multiple images for upload on a crispy image field, it shows all the file names of the selected images as a list in that widget. However, in my case it just shows the name of one of the files, multiple times (to be precise: for every file selected it shows the name of one of the files once). For example, if I select three files with different names, one of which is called 'kangaroo.png', the widget looks like this: Now I've pinned down the problem to this little snippet: <div class="custom-file "> <input type="file" name="images" class="form-control fileinput fileUpload form-control-file custom-file-input" multiple accept="image/*" id="id_images"> <label class="custom-file-label" for="id_images">Choose file</label> <script type="text/javascript" id="script-id_images"> document.getElementById("script-id_images").parentNode.querySelector('.custom-file-input').onchange = function (e){ var filenames = ""; for (let i=0;i<e.target.files.length;i++){ filenames+=(i>0?", ":"")+e.target.files[0].name; } e.target.parentNode.querySelector('.custom-file-label').innerHTML=filenames; } </script> </div> The problem lies in the line that reads: filenames+=(i>0?", ":"")+e.target.files[0].name;.

Django monkey patching model with method seems to work correctly as instance method - am I missing something?
I am using Django 3.2 and I am having to monkey patch a model, based on some conditional logic. myapp/models.py class Foo(models.Model): # fields ... # methods ... pass in console from myapp.models import Foo def something(obj): return obj.id # Monkey patching the class (model) setattr(Foo, 'mysomething', something) # Fetch an instance form db f = Foo.objects.all().first() f.mysomething() # return 1 (correct) My surprise is the fact that the something method is not accepting an argument, and instead, seems to be using the argument specified in the definition (obj) as a synonym for self - and therefore, the method is acting like an instance method. Can anyone explain the technical reason why this is happening - and is this documented (and therefore consistent) behaviour I can rely on in my code? -

Django models: dynamic inheritance from classes defined in standalone app
I am using Django 3.2 I have written a standalone app social that has models defined like this: from abc import abstractmethod class ActionableModel: # This MUST be implemented by ALL CONCRETE sub classes @abstractmethod def get_actionable_object(self): pass # This MUST be implemented by ALL CONCRETE sub classes @abstractmethod def get_owner(self): pass def get_content_info(self): actionable_object = self.get_actionable_object() ct = ContentType.objects.get_for_model(actionable_object) object_id = actionable_object.id return (ct, object_id) # ... class Likeable(models.Model, ActionableModel): likes = GenericRelation(Like) likes_count = models.PositiveIntegerField(default=0, db_index=True) last_liked = models.DateTimeField(editable=False, blank=True, null=True, default=None) # ... in my project (that uses the standalone app), I have the following code: myproject/userprofile/apps.py class UserprofileConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'userprofile' verbose_name = _('User Profile') def ready(self): # Check if social app is installed from django.apps import apps if apps.is_installed("social"): # check some condition # inherit from social.Likeable # ... ? How can I dynamically get my model userprofile.models.UserAccount to derive from Likeable?
