Using setConfigXML in the API Mate
View gist:95042bca628fb6924286
  • Access the API Mate:

  • Create a new meeting.

  • Join this meeting to make sure it won't be removed from the server in case you take too long to run the other steps.

  • Use getDefaultConfigXML via GET to get the default config.xml.

  • Copy and paste this config.xml into a new file. Edit it to remove any special characters (e.g. you might have HTML tags in the copyright field, so you have to remove or escape them).

  • Edit your config.xml according to your needs.

  • Put the edited XML content in the "XML for setConfigXML via POST" field in the API Mate.

  • Instead of using the API Mate to call setConfigXML (don't just click in the link), use another tool that runs outside of the browser. curl is a good option. First, copy the link the API Mate generated to setConfigXML. It will be a really long URL. Then use it with curl (replace <link> by the URL):

Organize javascripts and stylesheets like views in rails 3.1
Call the helpers 'javascript_include_tags_for_action' and 'stylesheet_link_tags_for_action' in the headers section
of your layout to automatically include javascript and stylesheet files for the current controller and action.
The files are included only if they exist. It is first included the file for all the actions of acontroller (e.g 'events/_all.js')
and then the file for the current action (e.g. 'events/show.js').
You can organize javascripts and stylesheets like views are organized.
Assuming you have the controllers "Events" and "Spaces":

A custom condition for God that checks for change in a file (usually tmp/restart.txt)

You can’t perform that action at this time.
