Redirect a user to previous page django
Let's say we have a simple django app with a blog model. There are only 3 pages: Home page Blog index Blog post detail The blog posts are listed in 3 locations: In a slider on the home page In the blog index (of course) At the bottom of a blog post There are 2 main ways of using breadcrumbs I've seen on a site: Home / Blog / Blog Post < Back I want to be able to have the "< Back" button go back to whichever the original source came from. I'm aware this could be done with JavaScript. But with Django, I've heard people say on another post that "you shouldn't redirect in template, you should do it in view", but to me that makes no sense as how is the view supposed to know which page to go back to automatically? Anyways, I'm trying to see is: How would you link back to the source page you arrived at a blog post from (i.e., another post, the home page, or the blog index) using django views or in the django template? -

Why to use a url field in serializers in django rest framework?
Hello guys I am new to django rest framework, I have seen lots of posts about rest framework and have seen people adding url fields to the serializer even though it isn't there in the model. Can someone tell me why we should use this? I have a postserializer like this without url field and I am able to get the response in postman when I run the code. class PostSerializer(TaggitSerializer, serializers.ModelSerializer): user = serializers.ReadOnlyField(source='user.username') tags = TagListSerializerField() class Meta: model = Post fields = ['id','title', 'user', 'tags', 'image'] What advantage I get when I add a url field to this? Is it something related to connecting to frontend or a mobile application? Please do enlighten me about this. Thank you -

How to scrape data faster with selenium and django
I am working on a web scraping project. In this project, I have written the necessary code to scrape the required information from a website using python and selenium. All of this code resides in multiple methods in a class. This code is saved as scraper.py. When I execute this code, the program takes sometime between 6 and 10 seconds to extract all the necessary information from the website. I wanted to create a UI for this project. I used django to create the UI. In the webapp, there is a form which when submitted opens a new browser window and starts the scraping process. I access the scraper.py file in django views, where depending on the form inputs, the scraping occurs. While this works fine, the execution is very slow and takes almost 2 minutes to finish running. How do I make the execution of the code faster using django faster? can you point me some tutorial on how to convert the scraper.py code into an api that django can access? will this help in making the code faster? Thanks in advance -
Building a django detailview and listview without using <int:pk>
I'm building a django app that displays a database of employees and their salaries. It uses a postgres database. I'm struggling to figure out how to build a DetailView without using a primary key for the url. I think using a slug may be the solution but I'm not sure how to implement that and haven't had much luck searching online. My Listview for the list of all companies: class AllCompanies(FormMixin, generic.ListView): template_name = 'AllCompanies.html' form_class = SearchForm model = bigdatabase queryset = bigdatabase.objects.order_by().values('company').distinct() context_object_name = 'companies' Example Database snippet, bigdatabase: Company EmployeeName Salary Alpha Jim 100000 Alpha Tim 125000 Beta Bim 90000 My list view displays all unique company names as intended. However, I'm not sure how to proceed and build a detailview to display more info on each unique company. I'd like to show things like number of employees, median salary, etc. I've done something similar by building a detailview for employees, but that relied upon using their primary key in the url since each employee is unique. Since I have many entries for many companies in my database, how would I build a detailview and accompanying url structure to support that? Any advice or pointers as to … -
API Versioning: providing different data formats for a resource
PROBLEM: when you write an API for an SPA, If the the API's json response or data changes, the SPA changes accordingly. so there is no need to version the API. But when you write an API for a mobile app, things are different. take a library mobile app for example: in app version 1.0 people see 5 books that have one image each one. but in version 2.0 because of change in design, different images should be passed for these 5 books. in app version 3.0 some other books are added which shouldn't be shown in previous versions for some reason. in this scenario, we should have three different responses for /books API end-point. the solution that comes to my mind is that I should have different for the /books endpoint: /v1/books /v2/books /v3/books you get the idea. QUESTION: what is the best way to handle "providing different data formats for a resource"? is there any best practice or standard for this? If this challenge is not properly handled, the development gets hard as the app grows, -
Why is my React app not loading correctly in Edge 84 (chromium) but does in chrome?
I have tried a django/react app as well as a base react app made using the create-react-app command. Both end up breaking in one way or another. For instance, the align-items tag does nothing (tried center, right, left). On my django/react app I have a header that loads perfectly on chrome but all I see is a background color on edge. -
HyperSkill Task
Hello I have a problem Hypreskill task.Can you Help me Hyper car service Description When the next client's turn is coming up, the operator should process it pushing the button. It happens when one of the mechanics has finished the work and able to serve the next client. You cannot define in the application the exact time, so leave the task to the operator. When the "Process next" button is pushed the application chooses the next client according to the algorithm's priority: Until the line of customers to change the oil is not empty, they served first If "Change oil" queue is empty the line of customers to inflate tires served next Clients who want to get diagnostics served last. Immediately the number of chosen ticket appears on the screen for all the customers and the length of the appropriate queue become one client less. You need not save the ticket further, the only purpose of it now is to show the number on the screen. Objectives Your task is to make a POST handler for processing the next ticket. After the request is received, remove the appropriate ticket from the queue. The handler should process POST requests at "<base_url>/processing", … -
How to link Django and React URLs to perform actions?
In Django, I have my login URL set to 'api/auth/login'. When given a username and password, it will log that user in. Running 'python manage.py runserver', it will put that URL at 'http://127.0.0.1:8000/api/auth/login' However, my React project, when running 'yarn start' is at 'http://localhost:3000/' and giving it the extension 'api/auth/login', the url it attempts is 'http://localhost:3000/api/auth/login'. This does not work, but if I replace the URL extension with 'http://127.0.0.1:8000/api/auth/login', the login works as expected. How can I have the URLs work with my React app? Or is this not something that necessarily needs to be fixed? I do plan to host this project somewhere and am not yet sure how the URLs will work out.. -
How to update a DateTimeField ONLY WHEN a BooleanField is checked from False to True?
# models.py class Appointment(models.Model): # not including some model fields and instead focusing on the model fields that are of concern records_sent = models.BooleanField(default=False) record_sent_date = models.DateTimeField(blank=True, null=True) records_received = models.BooleanField(default=False) record_received_date = models.DateTimeField(blank=True, null=True) # views.py class AppointmentUpdateView(UpdateView): model = Appointment fields = ['records_sent', 'records_received'] def form_valid(self, form): """ Update sent/received datetimes to current time when sent/received is checked from false to true. """ appointment = self.object if form.instance.records_sent: appointment.records_sent_date = timezone.now() if form.instance.records_received: appointment.records_received_date = timezone.now() return super().form_valid(form) My main concern has to do with my if-statement logic in my Class View's form_valid method. Currently, if my BooleanFields are checked True via POST request, the timezone updates to now(), which is fine. But let's say I set records_sent=True on 2:00 pm. If I set records_received=True on 4:00 pm, records_sent ALSO updates its time to 4:00 pm because the POST request sent records_sent AND records_received = True in the form, subsequently triggering the if-statement again when it should be only applying to records_received. How can I make it so that datetime.now() triggers ONLY when booleanfield is set from False to True, rather than having it also trigger from True to True? -
How to change the version of python run on apache for django
I have base GCP instance running Ubuntu 18.04. Running the python install gave me python 3.6.9. No problem initially. Now, I happen to be developing on 3.7 on my local machine. Until now this has not caused any issues with the Django apps I am developing. However, I am now developing an app that uses the module os.subprocess. It turns out that there are differences between 3.7 and 3.6 for this module. So I have successfully installed 3.7 on the server using sudo add-apt-repository ppa:deadsnakes/ppa sudo apt-get update sudo apt-get install python3.7 I ran sudo update-alternatives --config python3 and made sure it was active on the correct version. Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/bin/python3.7 2 auto mode 1 /usr/bin/python3.6 1 manual mode 2 /usr/bin/python3.7 2 manual mode Now, I can run programs on the command line and it runs 3.7. However, even after restarting appache (indeed, I even restarted the VM). Django is still running with v 3.6. I even ran this command to see what version the user www-data is running. su - www-data -s /bin/bash -c 'python3 --version' and it confirms Python 3.7.9 (as I expect). What am I missing, why is apache still running 3.6.9 … -

Django RESTFUL + axios and Vue.js frontend

Point Django RESTAPI to URL and Port and get API calls from there
I currently have a python application running separately from Django that has its own API calls in JSON format on localhost:8080 that is currently in production and cant be taken offline atm So I'm thinking of a momentary workaround until I can make it a better so here is what I'm trying to do I would like to access the API calls in the above application via Restful API in Django so that I can bind them to fields in a frontend that I created. Django is running on port 8081 The only guides I've found on Restful is within Django 'How to create a restful application IN Django' But nothing on telling Restful to look at a URL and port and get the API calls from there. (yes this sounds like the long way around but I don't have a choice atm, will need to make the application a bit better where the application running on port 8080 is within Django but that's going to be a few thousand emails and calls and PT) if I go into Postman and do calls there and export the code under Python - http.client and import it into my models.py and try … -
