Redmine plugins scripting

Question

I'm new to javascript, Redmine and RoR. So far I have read and understood the plugin development tutorial. But when I try to do things on my own they won't work...

If I use this:

<% content_for :header_tags do %>
<%= javascript_include_tag 'script', :plugin => 'my_plugin' %>
<% end %>

it will generate the correct link code on page source but there will be no scripts loaded to redmine_root/public/plugin_assets. Is that supposed to happen?

I would like to make this hello world example work.

But as far as I can understand, it will never work on the whole Redmine app if the scripts don't get loaded to redmine_root/public/plugin_assets.

If someone can help me out with understand why the scripts are not loading and how to properly use scripts under Redmine I would be very grateful.

Answer 1

1. Is code sample copy-paste from your project code? Or You typed it manually with misprints? % and = signs are missed in some places, must be <%= ... %> or <% ... %>

2. What the content of redmine_root/public/plugin_assets folder? It must have plugin folder named same as your plugin, then images, javascripts and stylesheets folders, like here:

   redmine_root
     ...
     plugins
       your_plugin # your plugin name
       other_plugins
     ...
     public
       ...
       plugin_assets
         your_plugin # your plugin name, must match with your plugin name in redmine_root/plugins
           javascripts
             your_script.js
           images
           stylesheets
          other_plugins    
   

In this case javascript_include_tag will works correctly with standart parameters (script and plugin names).
