Build-in views?
I installed a module to Django and this module has ceertain views within itself. Also it comes with a demo to see the features. I am looking at the code from the demo for a while now but I cant figure out how a template is rendered over the build in views. The module i'm working with is swingtime: Here is an example: Excerpt from the template: <a class="plain" href="{% url 'swingtime-daily-view' prev_day.year prev_day.month prev_day.day %}"> URL Directory urlpatterns = [ url(r'^$', TemplateView.as_view(template_name='intro.html'), name='demo-home'), url(r'^karate/', include('karate.urls')), url(r'^admin/', include(admin.site.urls)), url(r'^docs/?$', RedirectView.as_view(url='/docs/index.html', permanent=True)), url(r'^docs/(?P<path>.*)$', serve, dict(document_root=doc_root, show_indexes=False)) ] So the url must somehow link to a built-in template i suppose? When I try to implement similar code in my project the url can not be reversed? And also: How would one edit the template for such a build in view? Thank you! -
Heroku Deployment with Django: Webpack Bundle returns content of index.html instead of actual bundle
The application runs fine in development, but once in production the generated webpack bundle file is serving the contents of index.html and not all the bundled modules and dependencies. Whenever I check the bundle file on the server, everything seems alright, but the same path is served differently on the client. webpack.config.js //require our dependencies var path = require('path') var webpack = require('webpack') var BundleTracker = require('webpack-bundle-tracker') module.exports = { //the base directory (absolute path) for resolving the entry option context: __dirname, //the entry point we created earlier. Note that './' means //your current directory. You don't have to specify the extension now, //because you will specify extensions later in the `resolve` section entry: [ './assets/js/index' ], output: { path: path.resolve('./assets/bundles/'), filename: "[name]-[hash].js" }, plugins: [ //tells webpack where to store data about your bundles. new webpack.NoErrorsPlugin(), // don't reload if there is an error new BundleTracker({filename: './webpack-stats.json'}), //makes jQuery available in every module new webpack.ProvidePlugin({ jQuery: 'jquery', 'window.jQuery': 'jquery' }) ], module: { loaders: [ // we pass the output from babel loader to react-hot loader { test: [/\.js$/, /\.es6$/, /\.jsx?$/], exclude: /node_modules/, loaders: ['babel'], }, { test: /\.css$/, loader: "style-loader!css-loader" } ] }, resolve: { //tells webpack where … -

Learning multi tables joining info django
While i find this post Django views.py Version of SQL Join with Multi Table Query helpful. It does not seem to help me with understading joining tables. I had earlier help on a question and I thought I got it. I am trying to do the following show (current) players on the Boston Penguins. Code I have currently trying to pull it is Player.objects.filter(team__all_teams__contains='boston', player__curr_team__contains="Penguins") Which by reasoning anyway puts me in the Player.objects of my model and should be filtering from my team all the teams with Boston which there is on and then should pull all the current players for that team. Even better than just giving me an answer is a link to a video or document that better explains this so I can study it better to learn the call functions. Models.py from django.db import models class League(models.Model): name = models.CharField(max_length=50) sport = models.CharField(max_length=15) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Team(models.Model): location = models.CharField(max_length=50) team_name = models.CharField(max_length=50) league = models.ForeignKey(League, related_name="teams") class Player(models.Model): first_name = models.CharField(max_length=15) last_name = models.CharField(max_length=15) curr_team = models.ForeignKey(Team, related_name="curr_players") all_teams = models.ManyToManyField(Team, related_name="all_players") views.py only line i need help with rest works fine if i take out that line "bostonp" : … -
No Reverse Match For Some URLs in Django 1.10
I am making an web app in Django 1.10 and am getting an annoying error which I cannot seem to resolve. In this project there are several Django app whose URLs function without problems and seem to have similar setup as the new Account app. However, this authentication app is giving me trouble. What's more, the account/register URL works successfully and inserts a user into the database. I am not sure why some URLs work and other do not. Here is the error: NoReverseMatch at /account/login/ Reverse for 'dashboard' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: [] Request Method: POST Request URL: http://localhost:8000/account/login/ Django Version: 1.10.6 Exception Type: NoReverseMatch Exception Value: Reverse for 'dashboard' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: [] I have the following directory structure: Project's url.py: from django.conf.urls import url, include from django.contrib import admin from django.conf import settings from django.conf.urls.static import static urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^account/', include('account.urls', namespace='account')), url(r'^orders/', include('orders.urls', namespace='orders')), url(r'^shop/', include('shop.urls', namespace='shop')), url(r'^cart/', include('cart.urls', namespace='cart')), ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Account app urls.py: urlpatterns = [ # url(r'^login/$', views.user_login, name='login'), url(r'^$', views.dashboard, name='dashboard'), url(r'^register/$', views.register, name='register'), url(r'^edit/$', views.edit, name='edit'), … -
Django's custom template tag deletes HTML content
I've created a custom tag to hide zero values from HTML. I use this for hiding currency formatted numbers when its values are zero. This is my custom tag: def hideifz(value): return '' if value == 0 else value The problem is that this tag deletes some of my HTML. This is the relevant part of my template: <div class="price"> <span class="price-new">{{ publication.price_record.low_price|CLP }}</span> <span class="price-old">{{ publication.price_record.high_price|hideifz|CLP }}</span> </div> This HTML is for showing product prices. publication.price_record.low_price and publication.price_record.high_priceare the prices of my product. If the product is in sale, it must have high_price != 0, and this value must be shown in the HTML. CLP is just another tag for currency formatting: def toCLP(value): if not value: return value return '$'+intcomma(int(value)).replace(',', '.') If high_price is not zero, the output HTML is okay. For example: <div class="price"> <span class="price-new">$75.990</span> <span class="price-old">$83.990</span> </div> In the other hand, if high_price is zero, some of my HTML is deleted: <div class="price">$21.990</div> Note that span.price-new and span.price-old were removed. Now, if I remove the hideifz tag, the output of the previous example look like this: <div class="price"> <span class="price-new">$21.990</span> <span class="price-old">0.0</span> </div> The spans are back when I remove the hideifz tag. I just … -
Django REST Framework: nested serializer create methods
What is the correct way to implement the nested create-methods? I have a structure like TopLevelSerializer() HigherMiddleSerializer() LowerMiddleSerializer() BottomSerializer() These are all of type serializers.Serializer, not serializers.ModelSerializer. All of these serializers map to objects I'd like to create and I have implemented the create methods. What I want to achieve is sending the data to TopLevelSerializer() only and it will handle all the rest and return a complete instance of TopLevelObject() with all the nested objects in place. I kinda got this done already, but I seem to be duplicating all the lower level create-method code in the higher level ones and can't seem to understand how to get the objects from the create methods I've implemented for the lower level ones. I tried something like this, but that's what lead me down the code duplication path. What's the correct way to handle this? -

Dynamic number of columns in Django template
I have recently tried to solve the challenge of handling a dynamic number of columns in my Django template (essentially working through a list containing lists that isnt standerdized). I pass two things to my view: test_array: an array that looks something like the following [[1,2,3],[1,2,3],[1,2,3]] numbers: in this case 3 (indicating the number of attributes in the sub lists I thought to solve this as follows: <tbody> {% for t in test_array %} <tr> {% for x in numbers %} <td>{{ t.x }}</td> {% endfor %} </tr> {% endfor %} </tbody> But the above returns no output. When I reference t.1, t.2 etc hardcoded this returns output. As such, what is the best way to handle a dynamic number of columns in Django? Or, is there a more elegant way to solve the above? -

how to deploy a dijango website on to a specific IP or domain name
i bought a godaddy linux hosting for my django website. I was not aware of that they do not provide any platform for python in there cPanel. When i have bought then i came to know about what mistake i have made. Reading about number of solutions on net i have fixed the problem to some extent.

Running a Django management command on Elastic Beanstalk using cron
I'm running a small Django web application on Elastic Beanstalk. It uses django-background-tasks to run some asynchronous tasks. This works locally, as I can run python manage.py process_tasks to run the tasks. However, I've been having a little more trouble getting this to work as desired after deploying to Elastic Beanstalk. I managed to get it working by including this "99_process_tasks.config" file in my .ebextensions folder (based on this link in the AWS documentation): files: "/etc/cron.d/process_tasks_cron": mode: "000644" owner: root group: root content: | * * * * * root /usr/local/bin/99_process_tasks.sh "/usr/local/bin/99_process_tasks.sh": mode: "000755" owner: root group: root content: | #!/bin/bash date > /tmp/date source /opt/python/run/venv/bin/activate cd /opt/python/current/app python manage.py process_tasks commands: remove_old_cron: command: "rm -f /etc/cron.d/*.bak" This worked, in that the asynchronous tasks were running and executing their code as expected. However, as a relative novice in this field (particularly when it comes to cron) I suspect that this probably isn't doing exactly what I want, as I'm envisioning that this is causing a new python manage.py process_tasks command to be run every minute. What I really want to be doing is running the command just the once (or ensuring that it's run if it's no longer running). I … -
