<!-- | |
Renders a collection of objects in an HTML table (developed under Rails 4.0). | |
locals: | |
* size: The size of the collection (required to determine when to close the table) | |
* ignore (optional): array of symbols which map to object attributes which won't be rendered in the table | |
* calls (optional): array of strings which map to methods to call against each object | |
* table_class (optional): class value to use for the table | |
* table_id (optional): id to use for the table | |
* style (optional): style value to use for the table | |
Example usage: | |
render partial: "collection_as_table", collection: @users, as: :item, | |
locals: { | |
size: @users.count, | |
ignore: [:updated_at, :created at], | |
calls: [['fullname'], ['is_admin.humanize', 'Is Admin?']], | |
table_class: 'tablesorter', | |
table_id: 'user', | |
style: 'background-color: white' | |
} | |
