[ckan-dev] Pylons context object

[Pabitra Dash]

Sure, I could do this way. Is there any difference in performance between passing data to a template vs calling a function inside the template to get the data? I am guessing passing data is a better approach.

Indeed...
But from a quick look, it seems that most of the snippet calls are inside a dedicated block, so overriding the snippet call to pass a new variable should not be a big deal. Except if you case is different..

Examples:

  {% block package_resources %}    {% snippet "package/snippets/resources_list.html", pkg=pkg, resources=pkg.resources %}
  {% endblock %}
  {% block package_tags %}    {% snippet "package/snippets/tags.html", tags=pkg.tags %}
  {% endblock %}
  {% block package_additional_info %}
    {% snippet "package/snippets/additional_info.html", pkg_dict=pkg %}  {% endblock %}

Passing variable to snippet would work only when you are overriding both the template that calls the snippet and the snippet itself. In my case I am overriding only the snippet.

If I remember well, it is possible to pass some variables to snippets without using function.
Here is an example:    {% snippet "package/snippets/resources_list.html", pkg=pkg, resources=pkg.resources %}

Hi Pabitra,

context object is not accessible in snippets and package_metadata_fields.html is a snippet. I had the same problem and I used helper functions instead.

Hi All,
 
Any idea why the context object (c) may not be available in a template. Jinja is throwing an error 'c' undefined. I am getting this error in my extended template 'package_metadata_fields.html' where I am trying to access the 'c.user' object.


 
Thanks
Pabitra
