iOS - Django Python - Oauth2
I am trying to build an authentication system for an iOS app. Those are the steps: The user will log via Google oauth and will receive an auth code. iOS app will send to BE this auth code and will exchange with an access token. The BE will create a new token using Django Oauth Toolkit and send back to iOS app and will be stored into keychain. Now the problem I have: When the app launches freshly (previously logged in), I try to use .onAppear and inside I have GIDSignIn.sharedInstance.restorePreviousSignIn, and make a call to Auth server that issued my token to verify if it is still active and renew it using the refresh token. The url that I want to use is /o/introspect/, but is there any way to send the token without sending client id and client secret? I don't want them to be exposed on the iOS app. Or should I create a new url that accepts only the token and verifies? Thank you! -
Django complex data display in template
I am not able to proceed with data display. My db is: type month user First 2023-05-01 1 second 2023-04-01 1 second 2023-05-01 1 First 2023-03-01 1 second 2023-02-01 1 First 2023-02-01 1 second 2023-02-01 1 I want to display this data in template like below: Type First data: user 2023-05-01 2023-04-01 2023-03-01 2023-02-01 1 Yes No Yes Yes Notes: I need to filter last 6 months data for each user, seperate them by type and display whether they were present in each month or note. I have tried regroup with below code: {% regroup datadump by type as ret_type %} <ul> {% for type in ret_type %} <li>{{ type.grouper }} <ul> {% for data in type.list %} <li style="padding-left:20px;">{{data.user}}</li> {% endfor %} </ul> </li> {% endfor %} </ul> I am not able to make table with each month for last six months and show it there. -
save django pghistory tracker
So I want to track some fields in model,therefore I used pghistory this is my code: @pghistory.track( pghistory.BeforeUpdate( "trailer_changed", condition=Q( old__rate__df=F("new__rate"), old__truck__df=F("new__truck"), ), ), fields=["rate", "truck"], model_name="loadtracker", ) but problem is that, if I change only "rate" field, it also saves unchanged value of "truck" field too, then when I want to display changes on front, I get messed up, because there is also unchanged values too, example: if I change only truck field 10 times, in DB result will be like this rate - truck value1 - changed_value1 value1 - changed_value2 value1 - changed_value3 value1 - changed_value4 value1 - changed_value5 value1 - changed_value6 value1 - changed_value7 value1 - changed_value8 ... how can I resolve this? that would be good if I save for unchanged field "None" or null or something else Btw, what is the best practice to save history tracker? for other models I have to track about 10 fields, and is it ok to use like that? or should I create tracker table for every field? -
Searching objects by pressing button in django
I want to create a search form but using button instead of text input. I have a table with categories and each category has a button that leads to subcategories that share this category. When I click the button I somehow want to send name of the category to the view and filter subcategories that will be then rendered to specific template. Here is my template: <table> <thead> <tr> <th>ID</th> <th>Category name</th> <th>Updated at</th> <th>Subcategories</th> <th>Edit</th> <th>Delete</th> </tr> </thead> <tbody> {% for category in categories %} <tr> <td>{{category.id}}</td> <td>{{category.name}}</td> <td>{{category.updated|date:"d.m.Y G:i:s"}}</td> <td><a href="#">Subcategories</a></td> <!-- This link should be modified --> <td><a href="#">Edit</a></td> <td><a href="#">Delete</a></td> </tr> {% endfor %} </tbody> </table> So as you can see I have a link 'Subcategories' which should open subcategory page where I will display all subcategories of that category Here is my models.py: class Category(models.Model): name = models.CharField(max_length=100, null=True, blank=True) icon = models.CharField(max_length=50, null=True, blank=True) updated = models.DateTimeField(auto_now_add=True) class Meta: verbose_name_plural = 'Categories' def __str__(self): return self.name class Subcategory(models.Model): category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True) name = models.CharField(max_length=200, null=True, blank=True) icon = models.CharField(max_length=50, null=True, blank=True) updated = models.DateTimeField(auto_now_add=True) class Meta: verbose_name_plural = 'Subcategories' def __str__(self): return self.name I have no idea how to do this.

Why DRF modelserializers are returning 400 error code instead of 404, for the objects (foreign keys) they couldn't find?
I've been using modelserializers for a while, without noticing that when we enter an out-of-range id in request_body for foreign key fields, drf returns a 400 status code instead of 404! Is it right to do so? How can we change this behavior to return 404 status code in our modelserializers? -

Model fields won't appear through Django development server. How do I fix it?

handle many html files with React and Django
I have a hybrid django+react implementation. Django renders the initial HTML, then react takes control. However, the URLs are managed by Django. In react, the index.js file is supposed to correspond with one html right? Please correct me if I'm wrong. So, which is the correct approach if I have several HTML files that need react. My index.js file looks like this: import React from 'react'; import ReactDOM from 'react-dom/client'; import './index.css'; import { EfestoComponent, WorkTimeComponent, AresComponent } from './components/pulseHome'; import { PulseComponent} from "./components/pulseHistory"; import reportWebVitals from './reportWebVitals'; const efestosData = JSON.parse(document.getElementById('efestos-data').textContent); const efesto = ReactDOM.createRoot(document.getElementById('efesto')); const worktime = ReactDOM.createRoot(document.getElementById('worktime')); const ares = ReactDOM.createRoot(document.getElementById('ares')); const pulse = ReactDOM.createRoot(document.getElementById('pulse')); efesto.render( <EfestoComponent objects={efestosData}/> ); worktime.render( <WorkTimeComponent/> ) ares.render( <AresComponent/> ) pulse.render( <PulseComponent/> ) As you can see, the efesto, worktime and ares components belong to 1 js file called pulseHome, it holds the components for a file called pulse_home.html. Then the pulse component lives in a pulseHistory js file which holds the components for a pulse_history.html. When I visit any of the two htmls, it raises the error: Uncaught TypeError: document.getElementById(...) is null of course, since the first elements are not present in the second html, and vice versa.

How to serve Files with Django Rest Framework

django connecting to mysql in docker gets "wrong" IP address
I am attempting to connect to a remote mysql db from my dockerized django app. This works as expected: In [2]: pymysql.connect(host='remote-host.com', user='user', password='bogus') Out[2]: OperationalError: (1045, "Access denied for user 'user'@'172.XX.XX.XX' (using password: YES)") In [3]: pymysql.connect(host='remote-host.com', user='user', password='secret') Out[3]: <pymysql.connections.Connection at 0x401ef682b0> But this does not (from within django runserver): File "/usr/local/lib/python3.8/site-packages/pymysql/protocol.py", line 221, in raise_for_error err.raise_mysql_exception(self._data) File "/usr/local/lib/python3.8/site-packages/pymysql/err.py", line 143, in raise_mysql_exception raise errorclass(errno, errval) django.db.utils.OperationalError: (1045, "Access denied for user 'user'@'192.168.80.4' (using password: YES)") So somehow the shell-based connection is picking up a 172/ IP address for the client (presumably the docker bridge IP - it doesn't correspond to my laptop's en0 IP at any rate), where the exact same code, exact same connection params within runserver causes the mysql server to see the IP of the docker container. Anyone know what's going on, and more importantly how I can prevent it? Attempted: Well, not really much I can do since I don't have access to modify mysql's accepted host list or how it determines the client IP. Expected: The same IP address to be used in both connections. -
Django: Generating a file on page load and deleting it upon exit
Something I would like to do in my Django app is: every time a user views page A, grab information from my database, generate an image based off this and display it to the user. Since I am regenerating an image each time I view the page, I would like it to be unique to each user and deleted when they leave page A to go to any arbitrary page B (and ideally when they simply click x on the browser too, but if not that's okay). So far I can generate the image file and save it just fine. I have tried a few things unsuccessfully and can't figure out how to go forward. Things I have tried: @receiver(request_finished) @receiver(request_finished) def handle_request_finished(sender, **kwargs): ... clean up files here ... My issue with this one is that it happens too quickly and won't load the picture on page A because it will be deleted already. Using a JavaScript function that activates when leaving the page paired with a function in my views.py In template.html: <script> $(window).on('beforeunload', function () { $.ajax({ url: pageLeaveUrl, // links to page_leave function in views.py type: 'GET', async: false // Ensure the request completes before page … -

BASE_DIR = Path(__file__).resolve().parent.parent TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": [os.path.join(BASE_DIR, "frontend/build")], "APP_DIRS": True, "OPTIONS": { "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", ], }, }, ] # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/4.2/howto/static-files/ STATIC_URL = "static/" # Default primary key field type # https://docs.djangoproject.com/en/4.2/ref/settings/#default-auto-field DEFAULT_AUTO_FIELD = "django.db.models.BigAutoField" STATICFILES_DIRS = [ os.path.join( BASE_DIR, "/frontend/build") ] I've tried debugging my settings.py, it seems like the BASE_DIR is never set correctly, im not able to understand os.path.join -
Django Admin - Add a tabularInline section referred to another class (without foreign key)
I'm developing a Django Admin interface for a sort of ecommerce. I have some database model linked using foreign key. In Django Admin interface, I want to show a TabularInline section inside Customer page to show me all items buyed by a specific customer but I have a classic error about "foreign key" because Customer model and OrderItems model are not directly linked. class Customer(AbstractBaseUser, PermissionsMixin): email = models.EmailField(_('email address'), unique=True) name = models.CharField(max_length=150) mobile = models.CharField(max_length=20, blank=True) is_active = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) objects = CustomAccountManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name'] class Meta: verbose_name = "Account" verbose_name_plural = "Accounts" def email_user(self, subject, message): send_mail( subject, message, 'l@1.com', [self.email], fail_silently=False, ) def __str__(self): return self.email class Order(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="order_user") full_name = models.CharField(max_length=50) email = models.EmailField(max_length=254, blank=True) address1 = models.CharField(max_length=250) address2 = models.CharField(max_length=250) city = models.CharField(max_length=100) phone = models.CharField(max_length=100) postal_code = models.CharField(max_length=20) country_code = models.CharField(max_length=4, blank=True) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) total_paid = models.DecimalField(max_digits=5, decimal_places=2) order_key = models.CharField(max_length=200) payment_option = models.CharField(max_length=200, blank=True) billing_status = models.BooleanField(default=False) class Meta: ordering = ("-created",) def __str__(self): return str(self.created) class OrderItem(models.Model): order = models.ForeignKey(Order, related_name="items", on_delete=models.CASCADE) product = models.ForeignKey(ToolTable, related_name="order_items", on_delete=models.CASCADE) price = models.DecimalField(max_digits=5, decimal_places=2) … -
Get param on anothe page and edit : Vue-Axios-Django-Python
I would like to retrieve the data passed as a parameter via the route and make one of the modifications, but I can't. This is my Python-Django code # CompanyApi @csrf_exempt def companyApi(request, id=0): if request.method == "GET": companies = Companies.objects.all() # companies = Companies.objects.first() # companies = Companies.objects.order_by("company_id").first() companies_serializer = CompanySerializer(companies, many=True) # companies_serializer = CompanySerializer(companies) return JsonResponse(companies_serializer.data, safe=False) elif request.method == "POST": company_data = JSONParser().parse(request) companies_serializer = CompanySerializer(data=company_data) if companies_serializer.is_valid(): companies_serializer.save() return JsonResponse("Added Successfully", safe=False) return JsonResponse("Failed to Add", safe=False) elif request.method == "PUT": company_data = JSONParser().parse(request) company = Companies.objects.get(company_id=id) # company = Companies.objects.get(company_id=company_data["company_id"]) companies_serializer = CompanySerializer(company, data=company_data) if companies_serializer.is_valid(): companies_serializer.save() return JsonResponse("Updated Successfully", safe=False) return JsonResponse("Failed to Update") elif request.method == "DELETE": company = Companies.objects.get(company_id=id) company.delete() return JsonResponse("Deleted Successfully", safe=False) This is my code is my CompanyEdit page <script setup> import axios from "axios"; import { computed, ref, onMounted, reactive } from "vue"; import { useRoute } from "vue-router"; import CardBoxModal from "@/components/CardBoxModal_JTO.vue"; import FormField from "@/components/FormField.vue"; import FormControl from "@/components/FormControl.vue"; import BaseButton from "@/components/BaseButton.vue"; import SectionMain from "@/components/SectionMain.vue"; import CardBoxWidget from "@/components/CardBoxWidget.vue"; import CardBox from "@/components/CardBox.vue"; const modalOneActive = ref(false); const form = reactive({ company_id: "", company_name: "", company_email: "", company_phone: "", company_address: "", company_city: "", … -
Django signal when model instance with custom field is deleted?
I've got a custom model field in my Django app: secret = VaultField(max_length=200) This takes the value passed and saves it to HashiCorp Vault and stores the path to it in the database, and retrieves it from Vault when accessing. That's all good, I can use this on many models. But now when I delete an instance of a model it doesn't delete it from Vault. I could add a post delete signal on all models that have the VaultField field, but that seems like a lot of duplicate work. Is there anything to add in the class VaultField(CharField): class? Or maybe a post delete signal just on a field being deleted? -
Django or Javascript/Node: learning times in relation to difficulty?
I've been using Python for years, but always for desktop apps. I know Html, Css and little Javascript, but I've never programmed in backend for websites. I would like to learn Django, but having a look I found it very difficult. Knowing Python well and knowing little about Javascript, does it take less time to learn Django from scratch to carry out projects of medium difficulty, or does it take less time to learn Node.js from scratch with Express? (also considering the time to learn Javascript at least sufficiently)
