How can i deploy Django to Heroku with static files

Не отображаются поля формы django в модальном окне bootstrap

How to compare DateTimeFueld with Date in Django filter funtion?

How to split a long line in a Django template needed for formatting?
I have a line like this in a Django template: {{ some_prefix }}{% if obj.obj_type == A_LONG_CONSTANT %}1{% elif obj.obj_type == A_LONG_CONSTANT %}2{% endif %}{{some_suffix}}: where some_prefix might be a ( or something longer, and some_suffix might be a ) or maybe even empty. I don't know how to break this up, since putting any whitespace in such a template make it look different in a browser. Think "( hi )" instead of "(hi)". Any suggestions? You might say, "Put this in python, not Django templates." However, I'm not sure how to split it up into a tag either. It depends on the template context. I see this question, but that's just renaming variable names, which might make this thing even more heinous. I think there's probably nothing to do. -
Strange Error with Django oauth-toolkit and Azure App Service. Returns 401 {"detail":"Error decoding token."} when attempting to authenticate token
Hi I am deploying an app to Azure App Service using Django Rest Framework with OAuth2 authentication handled by django-oauth-toolkit (https://github.com/jazzband/django-oauth-toolkit). Recently when trying to connect to my React frontend I have found out that I cannot successfully authorize despite having an access token. When I make a the following API call (as suggested by the documentation): curl 'http://exampleurl.azurewebsites.net/endpoint/' -H 'authorization:Bearer <sampletoken>' I get the following response: {"detail":"Error decoding token."} I cannot recreate this error locally nor can I find any information about this error anywhere online. I even searched the repository for the error to see if I could find what triggers it, unfortunately no luck. Has anyone else ever experience this or can give me some insight on what potentially occurred in my deployment to cause this? I also deleted out my old deployment and even app service to completely start from scratch and the problem persisted. -
How to set up Django Machina custom permissions
I am new to Django and python. I have been able to alter a custom user model so that the user signup form presents the user with categories and category subforums populated from Machina tables. An example would be a user choosing the category of "Biology" (category forum) and a subcategory of microbiology (subforum of the category "Biology"). When the users view the main forum page, I only them to see a couple of site wide forums and the category/subforum they chose upon registration. I am not sure how to customize Machina to accomplish this. I found the forum permissions handler.py here: https://github.com/ellmetha/django-machina/blob/a92041c2854bee6b80d418fabd4cec5caac91dc3/machina/apps/forum_permission/handler.py#L300 It seems to offer some possible ways to accomplish what I want to do, but I am not sure of a good approach. Any suggestions for customizing which forums users have access to? -

Django Taggit - Autocomplete Light (Guidance with configuring)
I have Taggit fully up and running and would like to configure Autocomplete Light in order to enable the Select2 dropdown when users select their preferred tags within my application. I have installed DAL, dal_select2 along with dal_queryset_sequence libraries. I already have a form created where my users can simply upload a photo, add content and a TagField.

Chained dropdown validation error. Form works
Creating a chained drop down following a tutorial. Everything works fine but it is throwing an unnecessary validation error. It is a basic 3 field form creating a person object with name, country and city.

In the tutorial they add the if/else argument and that solves the problem and error goes away. error: "Select a valid choice. That choice is not one of the available choices" In my case the error still shows up. If I ignore it and re select the city and submit, it works just fine. It is almost like having a pause at that line and the system suddenly realizes that there is more code. How do I fix … -
Is it safe to call emit_post_migrate_signal from within a Django migration?
Background My original issue that lead me to this was my desire to create a Group within a django migration (not a problem) and then also assign permissions to that Group within a migration (problem arises here). It seems that in Django that ContentTypes and Permissions are created post-migration. So migrations cannot assign Permissions to Groups because the Permissions don't exist yet. ContentType and Permission generation is triggered by the post_migrate signal, which appears to be sent automatically after all migrations have been applied. There is this work around, in which you manually call emit_post_migrate_signal from within your migration. This will generate all ContentTypes and Permissions, and then the migration can indeed successfully apply them to the Group. Question My question is: is this actually safe to do? I can't find any documentation on the emit_post_migrate_signal function, and emitting a post_migrate signal in the middle of a migration seems like a recipe for something to go wrong (either now or in the future). -

VSCode Permission issues for File creation and Renaming in a Django App
I'm having an issue with creating another python file inside of the main app of my Django tree (I'm still learning Django so I'm not sure of the terminology). When I try to create a file inside of main part of the app named tweets I get this error. Unable to write file '/Users/ak/Dev/tweetme/tweets/forms.py' (NoPermissions (FileSystemError): Error: EACCES: permission denied, open Then I said fine, I'll just create the file in another directory and move it to the tweets folder, When I attempt this, I get the following error. Error: EACCES: permission denied, rename '/Users/ak/Dev/tweetme/tweetme/forms.py' -> '/Users/ak/Dev/tweetme/tweets/forms.py' From what I can read only people having this issues have downloaded some SSH shelling mod, which I don't have, nor do I know what that is. This problem came on suddenly, When I started this project I had no problem created files inside of the tweets folder. Does anyone have any insight into this?? Or how I can fix this? -

Django Rest Framework SQL Query CORS
I am building a tool where users can enter certain parameters and when they hit submit, it will query a mssql database and return some data. The data is passed through Django Rest Framework into a React frontend. The database is massive, so some queries might take several minutes to return. The issue I'm having is that for queries that take a long time, in the Network tab the status show CORS error: MissingAllowOriginHeader. The data returns fine for shorter queries, for longer queries after 30-45 seconds of loading I will get the CORS error. Also, note that this only occurs on a production IIS server, and works fine on my local server. I have tried the following in my settings.py already CORS_ALLOW_ALL_ORIGINS = True ACCESS_CONTROL_ALLOW_HEADERS = True How I'm getting the data from the sql server class SearchView(APIView): def post(self, request, *args, **kw): with connections["mssql"].cursor() as cursor: cursor.execute(sql_str) all = cursor.fetchall() How I'm making the request from React axios .post(process.env.REACT_APP_SEARCH, holder, { headers: { Authorization: "JWT " + sessionStorage.getItem("refresh"), "Content-Type": "application/json", }, }) -
