When exporting my data to Excel, I prompt the user to select his export template.<\/p>\n

But as per What I understand is you need to generate template dynamically for your excel export. I suggest you to have a look of ERB templating. In this you will find how you can generate templates dynamically then you can render them in rails.<\/p>\n Hope I have understood correctly and this answer will help you.<\/p>\n<\/li>\n Finally, I chose to import a configuration file coded in YAML. This seems the best way to import variables depending on a user’s choice (load a different yaml file at runtime)<\/p>\n<\/li>\n<\/ol>\n Originally posted 2014-01-27 02:21:14. <\/small><\/p>","protected":false},"excerpt":{"rendered":" When exporting my data to Excel, I prompt the user to select his export template.
