How to get current account id in django models.py
I want to get the id of the current account in django models.py. I know I can get the user object of the current account by adding 'request.user'. However, the function I am using requires the use of the self argument to be used in the condition, so 'request' cannot be used together. Please help.

Vue.js and drf images
I am currently trying to render images from my DRF to my vue.js template. I can see the image arrays in my console and have been successful using Postman with the get request but I can not seem to render the multiple images in my vue template. Im not sure whether I need to loop through the photos array in the lesson dictionary or link the id to the photo url? Any help on this would be really appreciated. Vue.js <template v-if="activeLesson"> <h2>{{ activeLesson.title }}</h2> {{ activeLesson.long_description }} <figure class="image is-square"> <img v-for="(photo, index) in activeLesson.photos" :src="activeLesson.photo_url" :key="index" /> </figure> <script> import axios from 'axios' export default { data() { return { course: {}, lessons: [], comments: [], activeLesson: null, errors: [], photo_url:'', comment: { name: '', content: '' }, } }, async mounted() { console.log('mounted') const slug = this.$route.params.slug await axios .get(`/api/v1/courses/${slug}/`) .then(response => { console.log(response.data) this.course = response.data.course this.lessons = response.data.lessons this.photos = response.data.photos }) document.title = this.course.title + ' | Relate' }, methods: { submitComment() { console.log('submitComment') this.errors = [] if (this.comment.name === '') { this.errors.push('The name must be filled out') } if (this.comment.content === '') { this.errors.push('The content must be filled out') } if (!this.errors.length) { … -
Is it better to create a OneToOne relation or a custom filed? [DJANGO]
I want to create a Venue model and save the location object, here's my code that actually works: class Location(models.Model): latitude = models.FloatField() longitude = models.FloatField() address = models.CharField(max_length=100, blank=True) city = models.CharField(max_length=100, blank=True) class Venue(models.Model): name = models.CharField(max_length=255) location = models.OneToOneField(Location) As you can see, if I delete Venue the corresponding location will not be deleted, because OneToOne works so. Is it better to create a custom field, let's say LocationField, with latitude, longitude... properties and put it inside Venue, or is this the right solution? -
Django - Saving multiple optional objects with a CreateView
I'm working on a real estate app where users can apply to rent a house or apartment. I'm having trouble grasping the concept of saving multiple objects and tying them together. I want the form to allow 1 to 4 people to apply for a single property. I either want 1 page where the user can select the number of applicants and the form save X number of people objects or I'm thinking of adding 2 buttons, on one to save and complete (current person), and another to save and add a new person. Additionally, I want to add all the applicants to a single application table. so I can query my database to view all the applicants on a single application. I'm not sure the best way to handle that. models class Properties(models.Model): property_num = models.IntegerField() property_road = models.CharField(max_length=200) rent = models.IntegerField(default=1000) city = models.CharField(max_length=200) state = models.CharField(choices=STATE_CHOICE, max_length=25) zip = models.IntegerField() bedrooms = models.IntegerField() bathrooms = models.FloatField(max_length=3) sq_foot = models.IntegerField() description = models.TextField(default=bedrooms) is_active = models.BooleanField(default=True) thumbnail = models.ImageField(upload_to='static/images', blank=True) slug = models.SlugField(blank=True, null=True, unique=True, allow_unicode=True) class Person(models.Model): address = models.ForeignKey(Properties, on_delete=models.CASCADE) requested_move_in_date = models.DateField(default=datetime.now) first_name = models.CharField(max_length=200) middle_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) dob = models.CharField(max_length=200) driver_license … -

How to redirect a wrong url with the same pattern that a user messed up in django, without javascript
assume the following: Your model has: Products.slug urls: path('<int:id>/<slug:slug>/', views.product_detail, name='product_detail'), views: products = Products.objects.get(id=id, slug=slug) Someone goes to /products/1/brazil-nuts/, and it goes to the right page. But then someone copy/pastes the url wrong to: /products/1/brazil-nu/ Then you get a DoesNotExist error... Now you could "fix" this by not forcing the slug=slug argument in your query, but then the url is incorrect, and people could link from /products/1/brazil-nu-sjfhkjfg-dfh, which is sloppy. So how would I redirect an incorrect url to the correct one with the same url structure as the correct one (only id and slug arguments), without relying on JavaScript's window.history.pushState(null, null, proper_url); every time the page loads? I've already tried making the same url pattern to redirect, but since django uses the first pattern match, it won't work no matter where you put the url in your list. -
Adding edit photo page to django image gallery app using Python

Python/Django sorting a queryset by distance in REST framework
Currently, I am adding a field, 'distance', to a queryset after it's been created, and then returning it. However, I would like to sort the queryset by distance, if it's possible to annotate it. Currently, my model, GeoCache, has fields latitude and longitude as models.DecimalField(max_digits=15, decimal_places=10, null=True, blank=True). Using geopy, I can add distance to my queryset like this: user_location = (self.request.GET.get('latitude') , self.request.GET.get('longitude')) geocache_list = GeoCache.objects.all() for geocache in geocache_list: geocache.distance = geodesic(user_location, (geocache.latitude, geocache.longitude)).miles return geocache_list However, I would like to sort the queryset by distance, from lowest to greatest. However, when I try to annotate the search as such: geocache_list = GeoCache.objects.all().annotate(distance=geodesic(user_location, ('latitude', 'longitude')).miles) I get the error, "ValueError: could not convert string to float: 'latitude'" Is there a better way to annotate this so that I can sort by distance within the queryset? -
How to update the data of a POST view that I have already updated with the same AJAX function?
We used AJAX to launch a POST request with a set of data. We noticed that a piece of data was being sent incorrectly. After fixing it, we sent the request again but the web where we display the data is not updated, despite having checked that the request sends the data correctly. Could someone tell me how can I fix it please? This is my code: //ajax function to send graphs to backend $(document).ready(async function(){ await new Promise(r => setTimeout(r, 1500)); var canvas_elements=document.getElementsByClassName("chartjs-render-monitor") if (canvas_elements.length==2) { $('#bar-chart').addClass(function(){ const csrf_cookie=getCookie('csrftoken'); $.ajax({ url: "graphs/", type: "POST", data:{ type:$('#vot_type').val(), graphs:graphs_images(), }, beforeSend: function(xhr) { xhr.setRequestHeader("X-CSRFToken", csrf_cookie) }, failure: function(data){ console.log(error) } }).done(function(response){ console.log("Hecho") }); }); } }); We checked the console to see if the data was sent correctly, and as we can see, it sends the type and url of the graphs. console But when we check the web, it is not updated. web not being updated Thank you so much in advance. -

Django - How Do I Set A Default Value In A Form To Be The Current User?
quick beginner Django question because I haven't been able to find an answer that directly solves what i'm after, or doesn't add in a bunch of overcomplicated functionality I don't need with its answer. I have a basic Blog setup, with a model for users and their associated posts, and a form for creating new posts. However all I want is for the "Author" field on the form to be automatically populated with the currently logged in user, rather than being a drop down list of all the registered users. My Model: class Post(models.Model): title = models.CharField(max_length=255) author = models.ForeignKey(User, on_delete=models.CASCADE) body = models.TextField() post_date = models.DateField(auto_now_add=True) category = models.CharField(max_length=255) site = models.CharField(max_length=255) def __str__(self): return self.title + ' | ' + str(self.author) def get_absolute_url(self): return reverse('home') My Form: class PostForm(forms.ModelForm): class Meta: model=Post fields = ('title', 'author', 'category', 'site', 'body') widgets = { 'title': forms.TextInput(attrs={'class': 'form-control'}), 'author': forms.Select(attrs={'class': 'form-control' ,'readonly': 'readonly'}), 'category': forms.Select(choices=choice_list,attrs={'class': 'form-control'}), 'site': forms.Select(choices=site_choice_list,attrs={'class': 'form-control'}), 'body': forms.Textarea(attrs={'class': 'form-control'}) } To reiterate, I simply want the 'author' field in the post to be read-only and populated with the current logged in user. Rather than the user being able to select from a list of users. Thank you in … -

The way I set it up is like this: from background_task import background from datetime import datetime import pytz @background() def notify_users(**kwargs): my_datetime = datetime.now(pytz.timezone('US/Eastern')) print ("at the moment its",my_datetime) and the activation: notify_users(repeat=30, repeat_until=None) The output is this: at the moment its 2022-01-02 15:08:25.571196-05:00 at the moment its 2022-01-02 15:08:55.896407-05:00 at the moment its 2022-01-02 15:09:56.408215-05:00 at the moment its 2022-01-02 15:10:56.871663-05:00 at the moment its 2022-01-02 15:11:57.327631-05:00 at the moment its 2022-01-02 15:12:57.857382-05:00 at the moment its 2022-01-02 15:13:28.135571-05:00 at the moment its 2022-01-02 15:14:28.551105-05:00 Note that its not 30 seconds, only the second round, why? what am I missing here? -
