Django how to DRY code from view

I'm just starting coding in Django and I have code that repeat itself on a lot of pages.

for example:

<select name="seasons" id="season-id">
    {% for season in seasons %}
        {% if season_id|add:0 == season.id %}
            <option value="{{ season.id }}" selected="selected">{{ season.name }}</option>
        {% else %}
            <option value="{{ season.id }}">{{ season.name }}</option>
        {% endif %}
    {% endfor %}
</select>

In previous language I could use view helpers to make it more DRY. How can I accomplish this in Django.

You shouldn't be writing this template code at all. You should define a Django form and let that output the field.

Depends on what is repeating.

  1. You can nest templates. Probably not useful here.
  2. You can write your own template tags and template filters. further info

Extract the code into a separate template file and include it instead of repeating:

{% include "seasons.html" %}

FYI, you can also specify that you want to pass only seasons variable into the context of included template:

{% include "seasons.html" with seasons=seasons only %}
