You might be happier using Ruby to map your data to JSON, and then feeding
that to your JavaScript, rather than using Ruby to dynamically generate
JavaScript.
For example, if you wanted to map the data directly in the view, could do
so like this.
- mapped_faculties = @faculties.inject({}) { |a, fac| a[fac.id] = {} }
:javascript
var departments = #{mapped_faculties.to_json};
In general, I would recommend doing these types of transformations in the
controller rather than in the view itself, but the principle is the same.
