(Crossposting Note: This topic has been posted already at https://railsforum.com/topic/1933-link-to-with-array-parameter-for-url-what-does-it-mean , but did not get a reply so far)
I found in http://guides.rubyon...-a-partial-form the following example: link_to 'Destroy Comment', [comment.article, comment], method: :delete, data: { confirm: 'Are you sure?' } I was surprised to see an array as second parameter for link_to and would like to know the meaning of this construct. The website gives just the somewhat thin explanation Clicking this new "Destroy Comment" link will fire off a DELETE /articles/:article_id/comments/:id to our CommentsController, which explains the effect of this statement, but does not really explain the general mechanism behind this concept. I've looked up the API documentation at http://api.rubyonrails.org/, which gives for the second parameter of link_to the following choices (for the case that the first parameter is a string): A string containing the URL to link to, or A hash containing various options for the URL An array as parameter is not mentioned. It seems that the API documentation is not complete here. Or did I look at the wrong place? Please could someone explain this syntax to me, and also point out, where I can find a more detailed description of the API? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
