Search with sorting mongodb
My data in mongodb: [{ "name": "Foo", "points": [{ "order": 1, "point_name": "A" }, { "order": 2, "point_name": "B" }, { "order": 3, "point_name": "C" }] }, { "name": "Bar", "points": [{ "order": 1, "point_name": "B" }, { "order": 2, "point_name": "C" }, { "order": 3, "point_name": "A" }] }, { "name": "Fizz", "points": [{ "order": 1, "point_name": "C" }, { "order": 2, "point_name": "B" }, { "order": 3, "point_name": "A" }] } ] I'm doing a search for B -> C the result should be Foo, Bar How the query will look through Django ORM ? Perhaps this can be done easily by rebuilding data or by using hashing functions. Thank you! -
Can django admin.py be replace with a directory?
I know I meant to give what I've tried but I just want to know if the functionality is available first. I'm build a project which is basically only using the django admin functionality (ie I'm not building custom views or if I am I'm building them within the admin functionality). It is making admin.pyrather large and I just wondered if it is possible to do something similar to models and models.py can be replaced by a models directory with init.py defining where the models are found. If the answer is yes, could you point me to some documentation? -
Copy Django App to a New Project but Model Data is Lost
I made a development django project on my pc, and I added a bunch of data for one of the apps "things" by logging in the ADMIN panel. When I copy and paste this app folder into a new project on Ubuntu, add this app in setting, then I find all the data in the model is gone. I used "makemigrations, migrate". Still nothing. What should I do to have those data in this new project? -

How will I use template context variable's value inside Django template tags?
In Django, I have seen the trans tag, it is useful to place translation strings in templates. {% trans 'Rishikesh' %} But I want to use dynamic value in place of 'Rishikesh' that is being passed by my view function. Let you assume my view function named index as follows. def index(request): return render(request, "index.html", {"username": "Rishikesh"}) My question is, I want to use the value of username as value of trans tag in my template as something like following. {% trans "{{username}}" %} I think, I am right but it doesn't work?

Issue with Django Template for loop
so I did some searches but couldn't find the answer to my particular issue... What is happening is that: I have a model named section which have section_title field. This field can have spaces, for example: "First Section". When I pass this to Django, I am removing the space in Python with replace(), and created a filter on Django which also removes the space like so: @register.filter(name='replace_char') def replace_char(value, arg): return value.replace(arg, '') Then on my template: {% for subsection in section.section_title|replace_char:" " %} The issue is that subsection is being shown as each character from section_title, instead of the list that section_title references. Here is the dictionary being passed to the template: {'sections': [< Section: First Section>, < Section: Second Section>], 'FirstSection': [< Subsection: Subsection 1>, < Subsection: Subsection 2>], 'SecondSection': [< Subsection: Bla1>], 'teste': ['1', '2', '3']} If I hardcode: {% for subsection in FirstSection %} It works... Any ideas? Thanks! OBS: I removed the spaces because I thought they were causing the issue, but apparently not. -
Oauth2, Django Backend, Implicit Token Authorization
So I've written a chrome application that uses chrome "WebAuthFlow" in the chrome.identity API. I've got a Django-Based site running on my computer at the same time, and with a login button in my chrome extension, I can use the webauthflow with my site and client to exchange tokens. I believe I need to use this implicit token scheme because my chrome extension is in javascript. The issue I am having is that while I would like users to be able to log into or out of the app - no matter which user the client 'belongs' to, which user is logged in to my domain currently (csfr; session cookie) or which user has loggin into through the webauthflow of the extension, when using the line return HttpResponse(User.objects.get(username=request.user), status=200) In my views, I am always returned with the username of the admin. Same goes for querying the admin -- Am I stuck in a session? How can I manually log out to test this? I have been completely unable to change this response at all - I want to have the user have logged in through the webauthflow and was expecting when I sent the username back to see the … -

Docraptor API Django get PDF to download
I am trying to use Docraptor in Django 2.0 and Python 3. I can get the PDF to generate to their website but not download to my system. Here is their code from https://github.com/DocRaptor/docraptor-python What needs to change to download the pdf file? doc_api = docraptor.DocApi() try: create_response = doc_api.create_doc({ "test": True, "document_content": "<html><body>Hello World</body></html>", "name": "docraptor-python.pdf", "document_type": "pdf", }) file = open("/tmp/docraptor-python.pdf", "wb") file.write(create_response) file.close() print("Wrote PDF to /tmp/docraptor-python.pdf") except docraptor.rest.ApiException as error: print(error) print(error.message) print(error.code) print(error.response_body) I am guessing there is some sort of HttpResponse missing? This seems like a great way to produce PDF files once I overcome this issue. Their tech support is great but documentation a bit short. Thanks. -
Django model form not saving all fields to db
Django 1.11 Python 3.6 Allauth (without the social part for now) Sqlite3 db backend I am working my way through building a Django site. Allauth is handeling the basic registration/login stuff. I have a user profile that has a foreign key relationship into the user table -- it is not an extended user model per se. It is a model that links to the user table. I have a view and a form that display the profile form. I have html5 form validation plus some form validation set up that seems to work. If I enter bad form data and submit then the various field errors are reported. If I enter all the required data and hit submit a record is created in the db but not all form fields with required values are inserted into the db table. I will get first & last names, phone and birthdate. The address info never makes it to the db. I do not see any errors reported. Sorry for the length of the supporting material...

Filtering Distinct and Ordered Data
I'm trying to create a messaging App where user can see the list of people who messaged him & also whom he messaged, so that he can click on their names & see the conversation occurred. Problem is that I couldn't filter out the distinct & ordered list of users who messaged request.user or whom request.user messaged. Here's the Model, class Message(models.Model): sender = models.ForeignKey(User, related_name="sender") receiver = models.ForeignKey(User, related_name="receiver") msg_content = models.TextField(max_length=8000) created_at = models.DateTimeField(auto_now_add=True) This is what I tried in view, def profiles(request): users = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user)).values('sender__first_name', 'receiver__first_name', 'receiver__id', 'sender__id').annotate(Max('id')).order_by('-id__max') return render(request, 'chat/users.html', {'users': users}) Here's the template, {% for user in users %} {% if user.sender__id != request.user.id %} {{ user.sender__first_name }} {% else %} {{ user.receiver__first_name }} {% endif %} {% endfor %} This code seems working fine but it's returning the same user twice as long as request.user sent him a message & he replies back to it. How can I solve this issue? Thank You . . . -
Python/Django - Value is reverting back after for loop
I'm trying to pass the URL's of a list of photos to the template. I'm concatenating my MEDIA_URL to every photo name. When print(a) is run, I can see in the console that the concatenation was successfully added. The result is something like media/photo.jpg. However by the time the loop finishes, the result reverts back to the original photo.jpg as if no concatenation happened. print(photos) shows a list of photos with no changes. Why? def get_property_data(request): property_id = request.GET.get('id') photos = ListingPhoto.objects.values_list('photo', flat=True).filter(listing__id=property_id) for a in photos: a = settings.MEDIA_URL + a print(a) print(photos) return JsonResponse({'property': list(photos)}) -

Git/Heroku - How hide my SECRET_KEY?
Im using Python and Django to create a Heroku web app and Heroku gives me this error after the command 'git push heroku master': ModuleNotFoundError: No module named 'dlist.secret_settings' when attempting to do this: #settings.py from .secret_settings import * # from secret_settings.py import * doesn't work for some reason. Here is what secret_settings.py (which is in the same folder as settings.py) contains: #secret_settings.py SECRET_KEY = 'string here' The problem is, this works when I test my web app on my local server (ie http://127.0.0.1:8000/), but its not working when I push these changes to Heroku. All I want to do is hide my SECRET_KEY, per others advice, as you can see. Ive looked at others suggestions and I can't seem to figure it out, choosing this method because it was understandable. Very frustrating. Beginner friendly answers/steps are greatly appreciated. -
Import JSON Data to Django models
I'm building a Django Rest Api with an empty database as of now. I want to load a big JSON file I got from another API in my models. The models I created respect the data type as well as the names of the json types. What's best practice for this? Will an import script be the best solution? If so I'd like to know where to 'run' my import code, would running the code in my get APIView class be good? Thank you
