I create the plot in the django view and push the plot to the bokeh server to show the plot in my webpage. It all works quite good.

Now I want to do a live plot, every time when a new DB-Entry is created the plot should be updated. I'm not sure what is the best way. Or is there a way to push the update form the server so that every currently connected client gets the plot update? In my opinon it's okay to use something like a heartbeat-timer in your frontend which triggers a data fetch every second or so. Especially if you implemented caching on the backend.

A more sophisticated version could use something like django channels to handle the communication via web sockets. Basically your problem here is that browsers use a request-response pattern: they send a request and then get back an answer immediately. You have two options, polling the server periodically or some kind of notification system. Notifications could be long-polling, i. Now, the thing is that these notification systems don't integrate too well with a traditional Django deployment, since they result in an open socket and a corresponding hanging thread.

So if your webserver has 10 Django threads, one browser with 10 tabs could tie up all of them. Work is underway to change that, but in the mean time, unless you have a hard real-time requirement or lots of clients, just set a timer and poll every x seconds, where x depends on what latency is acceptable.

Depending on how your data is stored, I would probably put in a simple mechanism so that the server doesn't send the whole dataset each time, but only either what's new or a carry-on-nothing-changed return code.

A notification system gives you better latency with lower overhead, but it is probably also going to be more difficult to deploy, and will probably be overkill if this is just an app for internal use.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It is based on functionality originally developed for the Ummeli website. A LiveChat model can be instantiated on its own, or hanging of another content type. It subclasses jmbo. ModelBase to use the commenting, moderating, likes, etc. In the admin site, on any live chat model's change form view, there is a new button in the toolbar at the top right of the page to enable a moderator or expert to participate in the livechat, and respond to questions or posts.

A context processor checks for active live chats, and will add it to the request context for use in templates, and to modify URLs, if necessary. There are template tags that will display an entire live chat and its comments thread in a template, as well as to display a banner advertising an upcoming live chat.

The jmbo application and its dependecies should also be installed, but will probably already be installed. Refer to the jmbo application's documentation for more information. You can add a context processor to add the newest live chat that is in progress to the request context. Skip to content. This repository has been archived by the owner. It is now read-only.

In an attempt to leverage this and help speedily deploy secure and maintainable web applications, the Django web framework was developed. The open-source web framework of Django, is based entirely on Python and follows the model-view-template MVT architectural pattern. The framework focuses on reusing components created to help with rapid development.

Given that it is Python-based, the framework is highly portable and can run on any platform and has support for several client-side frameworks, templating engines, and databases. In this tutorial, we will look at how we can create charts using the Django framework. We will use the FusionCharts Javascript library to create the charts.

To create a chart in a web app developed using Django, you will need the following items to be downloaded and installed on your system:. Note: You will require Python to be installed to start with Django and will also require working knowledge of Python to execute the code.

Creating charts using the Django Framework Step 1: Creating the project Run the following command to create a the myproject directory in the current directory. Step 2: Adding the dependencies Next, we will add the FusionCharts javascript files required to render the charts in the web application. Create a template folder inside the myproject directory.

Inside the template folder, create another folder named static. Copy all the javascript files extracted from the FusionCharts library into this folder.I make some basic assumptions about the readers of this tutorial. Now, well want the Django project to properly direct http requests to our chat application, as well as to the built in admin components. Most of this should be familiar from the Django tutorial.

The only potential addition is the use of the RedirectView. Django will serve the ui and javascript source portions, letting Twisted handle the chat api and server components.

Now, we'll need a couple of html templates for displaying chat room related information. The templates need somewhere to sit on disk, so create an app specific templates directory:. We'll have our index list all available chat rooms, so create a template for that.

Then create a page to serve as ui for an individual chat room. Again, this follows the basic pattern taught in the Django tutorial. This should now give us a functional Django application.

Let's make sure that it works properly, and that we don't have any typos. Create and define the structure of the database make a super user for it when you create itthen start Django:. For fun, try opening the chat room url in multiple browser windows, and then typing in it. Unfortunately, nothing interesting happens yet. That's where the Twisted chat server comes in - see Part 2. Step: Next, log in to the admin console and create a chat room.

Go to:. So, I was working on django 1. Thank you for the reply! I am using Django 1. Thanks for the tutorial! Hi I am trying to build a asynchronous chat app using django 1.

Create beautiful configurable charts from your models and display them on the django-admin index page or on django-admin-tools dashboard.

The charts are based on models and criterias defined through admin interface and some chart parameters are configurable in live view. This is application is fork of django-admin-tools-stats which has been reworked to display all charts through Ajax and made work with plain django-admin. The django-admin-tools are supported but not needed. Install the nvd3 and d3 javascript libraries. For installation with django-bower see section Installation of javascript libraries with django-bower.

Set library paths if they differ from the django-bower defaults:. Follow django-admin-charts installation according to previous section. Change DashboardCharts to DashboardChart in dashboard definition this is recomended even if dummy class is left for compatibility reasons. Run the following commands. These will download nvd3. You may also need to add some includes to your template admin base, see an example on the demo project:.
