Pointing Nginx to Gunicorn on a different server
I have a bunch of different services running across several lxc containers, including Django apps. What I want to do is install Nginx on the Host machine and proxy pass to the Gunicorn instance running in an lxc container. The idea is that custom domain names and certs are added on the Host and the containers remain unchanged for different installs. it works if I proxy_pass from the host to nginx running in a container, but I then have issues with csrf, which for the Django admin, cannot be turned off. Thus, what I would like to do is only run nginx on the host server connecting to the Gunicorn instance on the lxc container. Not sure if that will fix the csrf issues, but it does not seem right to run multiple nginx instances -

How to convert a False or True boolean values inside nested python dictionary into javascript in Django template?
this is my views.py context = { "fas": fas_obj, } # TemplateResponse can only be rendered once return render(request, "project_structure.html", context) in the project_structure.html and javascript section const pp = {{ fas|safe }}; I get an error here. because fas contains a False or True boolean value somewhere deep inside. fas is complicated and has lists of dictionaries with nested dictionaries. What did work is I did this context = { "fas": fas_obj, # need a fas_json version for the javascript part # because of the boolean in python doesn't render well in javascript "fas_json": json.dumps(fas_obj), I know now I have two versions because I need the original version for the other part of the template in the javascript const pp = {{fas_json|safe}}; Is there an easier way than passing the original and the json version? -

Django Class Based View - Generic detail View must be called with object pk or a slug in URLconf
So I have a program that takes in the currently logged in user and updates their profile image. Initially I had a function based view, and a url matching pattern (the url for accessing profile, and thereby editing it is localhost:8000/profile) #views.py @login_required def profile(request): if request.method=="POST": u_form=UserUpdateForm(request.POST, instance=request.user) p_form=ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile) if u_form.is_valid() and p_form.is_valid(): u_form.save() p_form.save() messages.success(request, "Your account has been updated!") return redirect('profile') else: u_form=UserUpdateForm(instance=request.user) p_form=ProfileUpdateForm(instance=request.user.profile) context={'u_form':u_form, 'p_form':p_form} return render(request, 'users/profile.html', context) #following line in URLpatterns of urls.py path('profile/', user_views.ProfileUpdateView.as_view(), name='profile'), It worked fine. However when I tried changing it to a class based view as below, it started giving errors #views.py class ProfileUpdateView(UpdateView): model=Profile fields=['image'] Case 1: I had this in urls.py URLpatterns path('profile/', user_views.ProfileUpdateView.as_view(), name='profile'), It gave an error - (https://i.stack.imgur.com/6mXfI.png)](https://i.stack.imgur.com/6mXfI.png) I don't understand why this error popped up because there is no page specific ID, like profile/1, profile/2 - just profile/ because the user is automatically identified by who is currently logged in hence no need to pass in a separate parameter in the url Case 2: after I added in pk parameter path('profile/<int:pk>/', user_views.ProfileUpdateView.as_view(), name='profile'), This error pops up (https://i.stack.imgur.com/Op9eQ.png)](https://i.stack.imgur.com/Op9eQ.png) I have been stuck for a day now.

django - swap foreign keys of one-to-one relationship in an atomic transaction
i have a Unit model with a one-to-one related handler defined as such: handler = models.OneToOneField('users.Handler', related_name="unit_obj", blank=True, null=True, on_delete=models.SET_NULL) i'm trying to update a set of units in an atomic transaction where the unit's handler_id foreign key can be set to null or any other handler_id. the problem is when handlers are being swapped. i initially tried saving the updated unit inside an atomic transaction. but as soon as unit.save() is called on the first unit i get an integrity error because the second unit still has the same handler_id. i was hoping that the atomic transaction would defer the integrity error on individual unit.save() calls and only throw the error at the end of the transaction if there actually were any. try: with transaction.atomic(): for unit_model in unit_models: unit = Unit.objects.get(id=unit_model['id']) unit.handler_id = unit_model['handler']['id'] if unit_model['handler'] is not None else None unit.save() except IntegrityError as e: print(f'Error saving units: {str(e)}') then i tried using bulk_update which i was sure would solve the issue. unfortunately i get the same error (duplicate key value violates unique constraint) even though i have confirmed that there are no duplicates in the list. it still seems to be applying the saves sequentially, though … -

Can i use doument.cookie to edit a cookie created with request.set_cookie in django project?
I am working on a Django project. Basically a simple game that uses x and y cordinates to determine the pos of the player on the map using js. So i figured that using cookies to "save" the progress of the player would be a simple way for what i need. Since i need to get these parameters from javascript file i was wondering if i could edit them directly from the file without the need of using a json to pass them to the views.py in order to check if the cookie is empty or has data when the user selects either load game or start a new one. I prefer doing it this way if possible to be able to maintain cookies without expiring thanks to django sessions engine since i haven't found a way to pass the data directly between the views.py and the .js files. Thanks for the help anyway -

How to add filters to jQuery.fancyTable (or alternative)
I'm currently using fancyTable to display a table of django results. I have been able to add a search bar and sortable columns (ascending/descending). I've also added "filters" but all they really do is update the search bar with pre-defined text The problem is that I want to be able to use these filters to only show text that matches exactly. For example, if I'm trying to filter by Stage looking for Prescreen I will currently get lines that include Prescreen, Passed - Prescreen 1, and Passed - Prescreen 2 I've already tried writing a function that sets the tr = display="none", but the pagination does not refresh, so I'm left with several blank pages. t Currently initiating fancyTable as such: <script type="text/javascript"> $(document).ready(function () { $(".sampleTable").fancyTable({ /* Column number for initial sorting*/ sortColumn: 0, sortOrder: 'descending', // Valid values are 'desc', 'descending', 'asc', 'ascending', -1 (descending) and 1 (ascending) /* Setting pagination or enabling */ pagination: true, /* Rows per page kept for display */ perPage: 12, globalSearch: true }); }); </script> Any ideas on how I can create these filters? I don't see anything from fancyTable about filters.
