AddScript duplicate between particle and CSS/JS atom

[jmshey90]

I'm using the CSS/JS atom to add a script: - { location: 'gantry-assets://js/eryc-datepicker.js', inline: '', in_footer: '1', extra: { }, priority: '1', contains, name: 'Date Picker' }

I also have a particle which loads it:

{% spaceless %}
{% do gantry.document.addScript(url('gantry-theme://js/eryc-datepicker.js'), 1, 'footer') %}
{% endspaceless %}

However, I get the script loaded twice. My understanding is that Gantry would only ever add one instance of the same script?

It's better not to mix atom and particle logic in the same file. But if you really want to, then you can try to do this in a particle:

{% set is_my_script = false %}

{% for atom in gantry.config.page.head.atoms if atom.type == 'assets' %}
  {% set attr = atom.attributes %}
  {% if attr.enabled %}
    {% for script in attr.javascript if script.location == 'gantry-assets://js/eryc-datepicker.js' %}
      {% set is_my_script = true %}
    {% endfor %}
  {% endif %}
{% endfor %}

{% if not is_my_script %}
  {% spaceless %}
  {% do gantry.document.addScript(url('gantry-assets://js/eryc-datepicker.js'), 1, 'footer') %}
  {% endspaceless %}
{% endif %}

Just an example. Perhaps there is a more elegant solution.
