Project description

This provides a back-end for Timelines JS 3. You can use external links to media or link to internal objects.

Initial Setup

  1. Install it via pip:

    pip install django-timelines

  3. Set TIMELINES_BACKGROUND_IMAGE_MODEL setting before you migrate the app. This model should be a photo management application that you use. This setting allows swapper to set up the relationship between that model and the timelines models:



Creating Adapters

In order to use an existing model in your timelines, you need to create an adapter for it. The adapter allows you to customize or map the information required by Django Timelines to your model. A couple of notes about adapters:

  • The adapter for a model does not need to be in the same application as the model. This allows you to adapt models installed via pip and which you have no control.

  • Django Timelines will import the adapters module for every installed application at startup. That’s a good place to put your adapters.

Adapter Example

from timelines.registration import registry, TimelineAdapter
from .models import Photo

class PhotoAdapter(TimelineAdapter):
    def get_headline(self):
        return self.instance.title

    def get_clickthrough_url(self):
        return self.instance.get_absolute_url()

    def get_credit(self):
        return self.instance.taken_by

    def get_text(self):
        return self.instance.description

    def get_media_url(self):

    def get_thumbnail(self):

registry.register(Photo, PhotoAdapter)

Using adapters

Adapters define several attributes and their accessor methods.

  • clickthrough_url and get_clickthrough_url(): a URL that, if provided, adds a “READ MORE” link to the description. Return None to omit link.

  • credit and get_credit(): the credit information for the media provided.

  • headline and get_headline(): the headline for the slide.

  • media_url and get_media_url(): the URL to the media for the slide.

  • text and get_text(): the text of the slide.

  • thumbnail and get_thumbnail(): a thumbnail for the timeline

To minimize the amount of work you have to do, the adapter is smart enough to look for the attribute name on the model instance. Instead of adapter.get_headline() you should just use adapter.headline so the adapter can use its internal logic to get the correct value.

When you access one of the required attributes, the adapter first tries the get_FOO() method. If the value returned is “falsey”_, then the adapter looks for the attribute on the model instance. So if your model already has a text attribute, you do not need to define a get_text method unless you wish to modify the value.

Defining media for a Timeline or Slide

Both Slides and Timelines (for the title slide) define a piece of media to show on the slide. Django Timelines allows either the specifying of an external URL or a link to an internal object. The benefit of an internal object link, is that it can provide the values for the other fields for you, and modifications of the object automatically appear on the timeline.

Even if you specify an internal object, you can still override the values provided by that model’s adapter.

  1. Specify the media:

    • For external URLs, simply enter the value in the Media URL field.

    • For internal objects, select the model from the Media content type field (only models with registered adapters are shown). Then click on the magnifying glass icon to open a window to browse for an object. You can also create a new object on the fly here.

  2. Set the content fields:

    • For external URLs, you must set appropriate values manually.

    • For interal objects, the help text under each of the fields will tell you the default as determined from the model’s adapter. You only need to enter values if necessary.

  3. Modify the background (optional)

    • Click Use media as background to use the URL or object specified in #1 as the background for the slide.

    • You can specify an alternative image to use as the background by specifying a Background image.

    • You can specify a color for the background (default is white).

Creating a Timeline

  1. Follow the instructions above in Defining media for a Timeline or Slide to specify the title slide information and background.

  2. In the Other Information section, you can alter the Scale, add Eras (see Eras below) and mark the Timeline as Published.

Adding slides to a Timeline

  1. Click on Add another Slide.

  2. Click on the magnifying glass icon.

  3. Select or create a slide. Once you have saved the Timeline, you will see summary data about the slide and a link to edit the slide.

  4. TimelineJS has the ability to organize events in the same row or adjecent rows based on their group. You can fill in the group attribute if necessary.

  5. Enter in the Order if necessary. Slides are automatically sorted by their date. However, since several events could have the same date, use the order field for fine control over them.

Creating a Slide

  1. Set a start date and optional time. See Dates, times and resolution below for more information regarding dates.

  2. Optionally set an end date and time.

  3. Set the media and content according to Defining media for a Timeline or Slide above.

Dates, times and resolution

You can specify a date with variable resolution. The allowed resolutions are:

  • Year (e.g. 1776)

  • Month (e.g. July 1776)

  • Date (e.g. July 4, 1776)

  • Datetime (e.g. July 4, 1776 at 5:24 PM)

Dates are sorted from lowest resolution to heighest resolution, in that:

  • Year resolution is sorted before January 1 of the same year. Consider it January 0th of that year.

  • Month resolution is sorted before the 1st of the month of that year. Consider it the 0th of the specified month.

  • Date resolution is sorted before Midnight of that date. Consider it the -1 AM of that date, since Midnight is 0.

  • Datetime resolution is sorted according to the time.


Eras are used to label a span of time on the timeline navigation component. Eras are reusable across Timeline objects. They consist of a start and end date and an optional label.
