与link_to助手结合的Rails地图方法？

Question

I have a model where I want all the records for the association , separated by 'and' and being displayed as a link ... So far I have a map or a link_to option in mind .... but I would like to combine both:

My desired result is this:

name and name2 and name3 etc. each being displayed as a link.

so

name... and name...

The association works fine and gives me all entries if I do

= model.associations.map(&:name).join(' and ') 

But 'map' does not work as a link. Is it possible to somehow combine map and link_to ?

For link_to I would use ..:

-model.associations.each do |a|
  =link_to a.name, a

This obviously would not separate the association entries with an 'and'. Any tip is highly appreciated. Thanks.

Answer 1

Try something like

= model.associations.map { |a| link_to(a.name, a) }.join(" and ").html_safe

But, I'd divide the logic between action and view. In the action

@items = model.associations

In the view

= @items.map { |a| link_to(a.name, a) }.join(" and ").html_safe

Answer 2

The easiest way for what you are doing is to just add and after the =link_to a.name, a . Since you are only outputting the data in a template, and not saving it in a variable for reuse later, there is no need for a map
