Description
In app/helpers/queries_helper.rb, there is:
def column_value(column, item, value)
content = ...
call_hook(:helper_queries_column_value,
{:content => content, :column => column, :item => item, :value => value})
content
end
In my xxx_helper_queries_column_value_hook.rb:
def helper_queries_column_value(context = { })
if context[:column].name == :action
context[:content] = "Ushiro"
end
end
I can change the parameter context, but when I checked in app/helpers/queries_helper.rb, I found that the variable content is not updated. So what's the proper way of using this hook? My guess is that this piece of code:
call_hook(:helper_queries_column_value,
{:content => content, :column => column, :item => item, :value => value})
content
should be revised to:
content = call_hook(:helper_queries_column_value,
{:content => content, :column => column, :item => item, :value => value})
content

Indeed, what is this hook for? And how should we use it? Does it allow to modify the display of an attribute in a list?
