#document_index_view_types=(hash_or_array) ⇒ Object

Parse params checkbox arrays into simple arrays. A group of checkboxes on a form returns values like this:

{"list"=>"1", "gallery"=>"1", "map"=>"0"}

where, “list” and “gallery” are selected and “map” is not. This function digests that hash into a list of selected values. e.g.:

["list", "gallery"]

end

#document_index_view_types_selected_hash ⇒ OpenStructWithHashAccess

A group of checkboxes on a form needs values like this:

{"list"=>"1", "gallery"=>"1", "map"=>"0"}

where, “list” and “gallery” are selected and “map” is not. This function takes [“list”, “gallery”] and turns it into the above.

Returns:

  • (OpenStructWithHashAccess) —

    keys are view types; value is 1 if enabled
