Django bootstrap modal not showing

How can I pull data from my database using the Django ORM that annotates values for each day?
I have a Django app that is attached to a MySQL database. The database is full of records - several million of them. My models look like this: class LAN(models.Model): ... class Record(models.Model): start_time = models.DateTimeField(...) end_time = models.DateTimeField(...) ip_address = models.CharField(...) LAN = models.ForeignKey(LAN, related_name="records", ...) bytes_downloaded = models.BigIntegerField(...) bytes_uploaded = models.BigIntegerField(...) Each record reflects a window of time, and shows if a particular IP address on particular LAN did any downloading or uploading during that window. What I need to know is this: Given a beginning date, and end date, give me a table of which DAYS a particular LAN had ANY activity (has any records) Ex: Between Jan 1 and Jan 31, tell me which DAYS LAN A had ANY records on them Assume that once in a while, a LAN will shut down for days at a time and have no records or any activity on those days. My Solution: I can do this the slow way by attaching some methods to my LAN model: class LAN(models.Model): ... # Returns True if there are records for the current LAN between 2 given dates # Returns False otherwise def online(self, start, end): criterion1 = Q(start_time__lt=end) criterion2 = … -
Sprinkling VueJs components into Django templates
I'm working on a Django site and I'm looking to "sprinkle" in some Vue components to the Django rendered templates. I'm working in a single repository and have webpack setup to create style/js bundles that I use within the Django templates. I'm struggling to get the functionality working how I'd like it, mainly regarding renderless Vue components, since I want to handle all (or at least the vast majority) of html within the Django templates and just use Vue components for some logic in some places. I'm using some of the advice from here but it didn't quite work as they'd suggested (although that's exactly how i'm hoping it can work) and I feel like I need to take advantage of scoped-slots. I am using the Vue esm distribution to include the Vue compiler. The setup I'm currently using is as follows: // webpack_entrypoint.js import Vue from "vue"; import RenderlessComponent from "./components/RenderlessComponent.vue" // I will also be registering additional components here in future for other pages // and I'm under the impression that doing it this way allows me to reuse the Vue instance // defined below Vue.component("renderless-component", RenderlessComponent) new Vue({ el: "#app" }) // components/RenderlessComponent.vue <template></template> <script> // Other … -

bulk_update: django-field-history vs django-simple-history
I am using Django v3.0.5. I have been using django-simple-history app in my project. It works well. However, I noticed that it doesn't work with bulk_update. This is known / documented (https://django-simple-history.readthedocs.io/en/latest/common_issues.html#bulk-creating-and-queryset-updating): Unlike with bulk_create, queryset updates perform an SQL update query on the queryset, and never return the actual updated objects (which would be necessary for the inserts into the historical table). Thus, we tell you that queryset updates will not save history (since no post_save signal is sent). Today, I found the django-field-history plugin which is very similar. I was wondering if anyone that has used this app can tell if it has the same limitation with bulk_update like django-simple-history. I browsed the user guide but could not not see anything relevant. In my models, I only need to track history for a fields so I am considering switching to this option if it works with bulk_update. -

How to resolve an error 404 for django-social?
I want to be able to login through social media. Followed all the steps (registered app), the login works just fine but does not go through because django does not recognize my url. This is my call to the api endpoint facebookLogin(token: string):any{ return this.http.post(environment.api + 'fblogin/', {token:this.token}).subscribe( (onSucess:any) => { localStorage.setItem(this._tokenKey, onSucess.token) }, onFail => { console.log(onFail) } ); } But I get the following error : POST http://127.0.0.1:8000/api/fblogin/ 404 (Not Found). From this I know there to be something wrong with my django urls. And indeed going to http://127.0.0.1:8000/api/fblogin/ gave me a page not found error and that it tried to match several other urls. However I can't see what is wrong with my urls URLS in my app from django.conf.urls import url, include from rest_framework import routers from . import views from rest_framework_jwt.views import obtain_jwt_token, refresh_jwt_token from social_django import urls router = routers.DefaultRouter() router.register(r'users', views.UserViewSet) urlpatterns = [ url(r'^', include(router.urls)), url(r'fblogin/', include(urls)), url(r'auth/', obtain_jwt_token), url(r'refresh/', refresh_jwt_token) ] URLS in my project from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('api/', include('Backend.api.urls')) ] Other URLS like http://127.0.0.1:8000/api/users/ do work.

DJANGO: Pass a specific variable from template to view when button is pressed
I am building an online store that displays products with various fields to show in the template (name, price, item ID, etc), and I am doing this for every product passed in. So when the page loads I have many tags that share the same name. My problem is that I don't know how to pass the item ID into the next view. This value is the unique identifier so I need it to perform a select statement from my database to retrieve all of the items information. That information can then be displayed on another page where the user can see all details and add it to their cart. I tried to use a hidden form and use POST to get the value but I can't seem to get the exact element that I want since there are many with the same div tag ID. When each item is hovered over, a button appears to view the item details. When that button is pressed, this is where I need to send the item ID from the labeled div tag into the next view. views.py # Products page to view all items def products_page(request): args = { 'products': products, } … -
How to debug django staticfiles served with whitenoise, gunicorn, and heroku?

How can I fetch all news headlines from nested tags?
For starters, i'm new in Python and i'm working with BS not too long. I am trying to get all the news headlines from all the articles on the website, but for some reason these loops doesn't work properly. But why?! I do not understand.. With this program code I tell the computer that I want to find and fetch all the 'a' tags that are inside multiple nested tags, isn't it? And i'm iterating over a nested tag to the next nested tag so i can fetch the "a" tag which contain the news headline. My code: url = "https://loudwire.com/category/news/" content = sessions.get(url, verify=False).content soup = BeautifulSoup(content, "html.parser") section = soup.findAll('section', {'class': 'blogroll row-standard carbonwidget-taxonomy outgrow no-band'}) for stn in section: blog = stn.findAll('div', {'class': 'blogroll-inner clearfix'}) for blogroll in blog: article = blogroll.findAll('article') for i in article: posts = i.findAll('div', {'class':'content'}) for wrapper in posts: a = wrapper.findAll('a', {'class': 'title'}) for link in a: print(link.get('title')) context = {'contex': link.get_text(strip=True)} return render(request, 'music/news.html', context) So, what am I doing wrong? Maybe you can show me where did i make a mistake and how to do this correctly? Thank you, any help will be invaluable! -
Django using custom icon in admin change list view
I want to have custom links in the change list view in Django admin. Currently, I can setup the links and get the three links in the last column: However, I would like to have three images instead of the text, but I do not know how to reference the static files for the images inside the corresponding models.py file.

Wndows IIS 10 will not serve static files from Django 2.2. . . How can I fix this?
The website displays to localhost without css, js, or images. I setup Windows IIS according to this blog including the final section about static files. The methods outlined are similar to answers from this question, this question, this blog, and this youtube video on how to serve static files from django with IIS. Django settings: STATIC_URL = "/static/" STATIC_ROOT = os.path.join(BASE_DIR, 'static') # tested in shell, it is where I expect at the same level as manage.py The directory "static" was created with manage.py collectstatic in the expected STATIC_ROOT location with all of the static files contained The static directory was then added as a virtual directory: Then I removed the django handler I created from the static directories handler mappings: I unlocked the handlers at the root: The django application did display properly, with static files, when I tried using Wampserver w/ Apache and mod_wsgi. Unfortunately, it appears windows IIS will be the better solution for other unrelated reasons. Not too mention Wampserver is a development server, not a production server.

Data structure for internally generated images on Django
Let's say I have a django app where many images are internally generated after post requests made by users. Where should I stock these images ? As it is internally generated and not uploaded by users, it does not seem necessary to use the file storage systems and the /media/ location. But it does not seem clever to use the /static/ directory either, as many images will be added (and removed) then they are not static. Moreover I'd like to use a model that contains the images and other information about them. What model field class should I use to handle these images ? As the images are not uploaded by users models.ImageField does not seem appropriate. Thank you :) -

How to access Django database with JS
I have developed a website for an interactive game (mafia) using Django (python), but then i realized i need the displaying data(such as list of alive players, player messages, list of voted for lynch players, etc.) to be real-time and update instantly, whereas my website needs to be refreshed in order to see the updated database content. This is how it looks After realizing that, I started learning JavaScript, but now that I'm almost done, I noticed that Django and JavaScript functions cannot be called interactively, meaning I can't do JS functions and change database attributes at the same time. So I need an interactive frontend that updates data instantly, while being able to access and change database attributes as well(JS doesn't do this apparently). What should I learn for that?

So I want to let a user message another user. I want the 'sender' field automatically to be 'request.user' and the receiver field to be the user whom the sender clicked on through their profile page. How would I go about passing those into the form? forms.py/InstantMessageForm class InstantMessageForm(forms.ModelForm): class Meta: model = InstantMessage fields = ('receiver','sender','message') def save(self, commit=True): user = super(InstantMessageForm, self).save(commit=False) user.receiver = cleaned_data['receiver'] user.sender = cleaned_data['sender'] user.message = cleaned_data['message'] if commit: user.save() return user views.py/instant_message def instant_message(request): if request.method == 'POST': form = InstantMessageForm(request.POST) if form.is_valid(): form.save() return redirect('dating_app:home') else: form = InstantMessageForm() context = {'form':form} return render(request, 'dating_app/instant_message_form.html',context) models.py class InstantMessage(models.Model): receiver = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) sender = models.ForeignKey(settings.AUTH_USER_MODEL, related_name= 'sender',on_delete=models.CASCADE ) message = models.TextField() class InstantMessage(models.Model): receiver = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) sender = models.ForeignKey(settings.AUTH_USER_MODEL, related_name= 'sender',on_delete=models.CASCADE ) message = models.TextField() instant_message_form.py {% extends "dating_app/base.html" %} {% load bootstrap4 %} {% block content %} <h1>Start chatting now!</h1> <div class='container'> <form method="post" action="{% url 'dating_app:instant_message' %}" > {% csrf_token %} {{ form.as_p }} <button type="submit">Register</button> </form> </div> {% endblock content %}
