How to save a django "with" template tag value and reuse it in other templates?
I have a template tag that reads values from the URL. For example the searched term is cancer. After searching, the next page that appears would have a with Searched terms: Cancer. And I would like the value cancer to appear in all of my webpages until the user does a new search. Pages I have work this way: Search.html > display.html > explore.html Search.html is where the user enters what they want to search for. I have a searchedterms.html which is included into all 3 templates and contains the Javascript code to read from the URL. By using a JavaScript code, I managed to display searched terms: cancer in display.html but in explore.html the value is empty. I want to be able to save "cancer" to the tag and use it in other templates. ?conditions=cancer in search.html: <input required="" type="text" name="conditions"> in display.html: {% with searched_terms='searchedterms.html' %} {% include searched_terms %} {% endwith %} in explore.html: {% with searched_terms='searchedterms.html' %} {% include searched_terms %} {% endwith %} in searchedterms.html: <div id="searched" class="container"></div> <script type="text/javascript"> var urlParams = new URLSearchParams(window.location.search); function getUrlParameter(name) { name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]'); var regex = new RegExp('[\\?&]' + name + '=([^&#]*)'); var results = … -

Django rest framework bulk: Correct URL syntax for bulk operations?
I'm attempting to carry out bulk DELETEs/PUTs on my Django API, mymodel inherits from the BulkModelViewSet In my urls.py file I define the URL used to interact with my model: router.register(r"v1/mymodels", mymodels_views_v1.MyModelViewSet) this allows me to GET, POST, PUT and DELETE on the URL (works perfectly at present): www.my-api.com/v1/mymodels/{{mymodel_id}} Can I use this same URL for bulk operations? If so, what is the correct syntax? eg: www.my-api.com/v1/mymodels/[{{mymodel_id1}},{{mymodel_id2}}] If not, what changes should I make? Thanks -
Cannot import python library on django server hosted on docker
I am running a django server on docker. I have added numpy and pandas in the requirements.txt file. Next I run docker-compose build . Both the libraries show as installed correctly. But now when I start the server and then run a python script that imports these libraries, the script fails to execute and I get no output. I tried executing the same script without importing those 2 libraries, and it executes properly giving out the expected print statement. What could have gone wrong here? -

django cannot find module named XX when importing with absolute path
I have a django project with following structure project folder |- mysite |- mysite |- __init__.py |- settings.py |- ... |- myapp |- __init__.py |- abc.py |- ... |- __init__.py |- manage.py When i use relative imports, it all works fine. But when I change to absolute imports, it raise error "No module named 'mysite.myapp'. I started my script in project/mysite folder, so I thought it should search all subdirectories and found myapp module, but clearly it didn't. And I did add myapp/apps.py class into INSTALL_APPS in the settings files. So what's wrong with my codes and settings thanks -

Processing classes for each request vs one POST method for them?
I am migrating a project from PHP to Django. In my PHP app, the admin panel has a table, and in each row there are multiple options that it looks for and processes each one differently. So for each request in those rows, I have made a processing class for it which handles it and redirects back to the admin panel. For example, "Approve" button pressed by a user from "manager" group works differently than a user from "superadmin". Right now I have a TemplateView like this: class ProcessLeaveRequest(TemplateView): template_name = 'process_leave_request.html' def get(self, request, *args, **kwargs): return render(request, self.template_name) My question is, should I make a POST method in this class for each request that will be coming from process_leave_request.html, or should I make a separate class for each of those requests? What is the best practice for handling multiple requests from a single page which all do different tasks? -

Calls to API Always Return “Authentication Credentials Were Not Provided” when accessed from Apple Shortcuts, but not from Postman
I’ve recently been developing a Django Application to auto-generate some schedules for me in TaskPaper form. I’ve been using django-rest-framework to automate a lot of the details of this but now I’ve come up against a problem I can’t fathom with authentication. I’m using django-rest-framework-simplejwt and the application is deployed on Heroku. When I test my app on my own machine I get the expected results, I can request the token and then using that I can request the data I want, all this is done using Postman. When I deploy the application to Heroku, and still use Postman again it all works as expected. However when I try and use Apple Shortcuts to request the data, getting the token is fine but when I try and GET the data using that token I get the error “Authentication Credentials Were Not Provided”. I looked through all the accepted answers and tried all the solutions there to no avail, so any help would be greatly appreciated and I can post any code snippets that might be required. -
