link-to

问题 I am using a link_to tag on my posts/index view and want to link it to my posts/show/id view with an anchor that makes it scroll down to the comments form. For some reason I can't get the anchor to work. Here is my code: In posts/index <%= link_to 'Add a Comment', post, :anchor => 'comment_form' %> This fails to append the # sign to the end of the link, so it is just localhost:3000/posts/id. I have also tried many variations for link_to, including: <%= link_to 'Add a Comment', post(:anchor =>

问题 I've ran into a ror problem using the link_to. Why does my link to use the GET method and my button_to use the POST method, after I specified my "method"=>"post" within the link_to parameters? View: <%= button_to "pdf", :action => 'getquote' %> <%= link_to 'pdf', {:controller => 'inventories', :action => 'getquote', :method => :post } %> Controller Method: def getquote @cart = find_cart respond_to do |format| format.pdf end end Terminal Output (Button/Link, respectively): Processing

问题 I'm viewing 1 product in show.html.erb and there's a link below that says "View other products from this company". This link_to connects to another non-restful action in same controller which retrieves from DB other products of same company as was shown in show.html.erb. Can link_to pass the :id of the current product in show to action it's rendering? I'm new to rails and please let me know if question is not making sense. I'm not sure if routes need to be defined as well. Thanks. products

问题 Ok, my situation. I have a nested resource of resources :projects do resources :campaigns end I want to make a view with controller with resources :portfolios I want to make a <% link_to %> that listed all campaigns which I can do, but when I try to route the path i can't make it link to a campaign.

问题 I'm trying to destroy a link from a User Show view. So from /users/1 , I want to access destroy action in teacher_student_links controller. The first attempt: <%= link_to 'destroy', :controller => "teacher_student_links", :action => "destroy", :id => @user.id %> This fails because it routes to "show" action in the specified controller. So first question: why does it point to the "show" action instead of "destroy?" I tried to enclose the above with parenthesis, and got a meaningless error as

问题 I am new to rails having just completed rails for zombies (railsforzombies.org) and am trying to build my first app (a blog). I have scaffolded a basic structure and made changes including changing routes adding partials and other improvements to the view as well as installing the Blueprint css framework.
