I have this html snippet which needs to be used in lots of places in the jinja2 templates:
<div class="usedalot">{{ somevalue }}</div> for example, in template1.html, template2.html. template3.html, this code is repeated several places
<!-- template1.html, template2.html. template3.html --> <div class="usedalot">{{ somevalue }}</div> ...... <div class="usedalot">{{ somevalue }}</div> .... <div class="usedalot">{{ somevalue }}</div> ...... Instead of copying and pasting, is there someway to use this code snippet as a block? The jinja2 template inheritance (with blocks) do not seem to solve this problem.

To reuse a Jinja template you use the Jinja built-in {% extends %} tag. The {% extends %} tag uses the syntax {% extends <name> %} to reuse the layout of another template. This means that in order to reuse the layout in listing 4-5 defined in a file base.
What you are looking for is called a macro.
Macros are placed in separate files (e.g., macros.html).
{% macro usedalot(somevalue) %} <div class="usedalot">{{ somevalue }}</div> {% endmacro %} You can then import your macros in other templates
{% from 'macros.html' import usedalot %} and then use them whenever needed
{{ usedalot(1) }} This will output
<div class="usedalot">1</div> As of Jinja 2.8, you can also now use block assignments to map a block (still can only be defined once) to a variable that can be used multiple times in the document.
Documentation is at: Block assignments
I just used the feature to drop my HTML page title block into both the title element as well as the meta property for Facebook's opengraph:title attribute.
{% set title_s %}{% block title %}MY DEFAULT TITLE{% endblock %}{% endset %} <head> <meta property="og:title" content="{{ title_s }}" /> <title>{{ title_s }}</title> ... </head> This seems to me to be a much more clean solution than defining a macro.
