How to add content for an external file

[Maxime Garnier]

High all,

I've been starting using Nikola and I have a question. I plan using a shortcode for a card on a "meet the team"-like page and I would like to call that shortcode with the path to a file (txt, possibly html or other) as argument that contains the content to write in the card.

I didn't figure out a way to do this. I am primarily using html files and the standard {%  include %} doesn't seem to work. Or maybe there's a better way to tackle the problem that I didn't thin of?

Anyways, thanks!

Best,

Maxime

For more context, what I envision for card.tmpl would be something like

<div class="card" style="justify-content: center">
    <img src="/images/${image_path}.jpg" alt="Jane" class="im-center"  style="width:50%">
    <div class="container">
      <h2> ${name} Doe</h2>
      <p class="title">CEO </p>
      <p>Some text that describes me lorem ipsum ipsum lorem.</p>

<!-- some way to upload text from a file? with %{content_path} -->

      <p>exa...@example.com</p>
      <p><button class="button">Contact</button></p>
    </div>
  </div>

which would be called in my main html by

{{% card name=Maxime image_path=me content_path=/files/location/me.txt %}}

Would something close to that be possible ?

Thanks!

If you want to read a file from within the template, you could write a
simple Python function for that and expose it in the global context in
conf.py - but note this will not track dependencies correctly. If you
want dependencies to be tracked, you need a custom shortcode plugin.

Another route might be to slightly abuse the post-list mechanism:
every person gets their own page, and the post-list shows them
(including metadata and post content).

A third option would be server-side includes, but those are pretty silly IMO.

Thanks for your answer! Seems like a bit of work.

Would it be easier to read the txt files and images from the page itself (and not the template)?

How would I go about writing a Python function in conf.py and calling it from the page?

Thanks!

Pages can't do that, in general. You can use a custom shortcode or a
reST include (if both files are reST).

Write a function as usual, and then put it in GLOBAL_CONTEXT ({"foo": foo}).

[Maxime Garnier]

Thanks I'll try that ! Or maybe consider switching to reST if the include works better !

Could I get a bit more detail on how to put the function in GLOBAL_CONTEXT and how to call it from a page please ?

Thanks !

def foo(bar):
return bar + " world"

GLOBAL_CONTEXT = {"foo": foo}

You can use this as ${foo("hello")} within a Mako template or {{
foo("hello") }} from a Jinja template.

Thanks a lot for your help, this might solve my problem!

Hi again,

seems like in the template when using ${foo("hello")} I can't get it to use the variable specified when calling the template with for example

(in the main page)

{{% template var = dummy %}}

${foo("${var})} in the template raises a Mako syntax error. Would something like this be possible so that I can call the template from the main page (that calls my function) with different parameters?

Thanks again!

Best,
