问题 I'm using Acts_as_follower in a wishlist app I'm working on. I think it should be working, but the button to actually follow another user is not. The follow button is in my user index view, and I can see it there, but it doesn't respond to being clicked. Any help would be appreciated. Here's my code: index.html.erb <div class="container"> <% @users.each do |u| %> <div class="col-sm-8 col-lg-4"> <div id="gifts"> <div class="box panel panel-default"> <h2><%= link_to u.name, u %></h2> <p> <table

问题 I have a model A und a model B and the relation is A has_many B (and B belongs_to A). I have a model, a controller and views for A and only a model for B. I want to create and edit the instances of B on the edit view of A ( url/a/1/edit).

Is there a recommended way to do this? What I want is to not break any of

问题 In my app that I am building to learn RoR, I have a similar situation like this question. Now my question is how to change my views for this?

问题 I came into work today to find that my project is throwing a syntax error for some reason, and I can't find a single thing about this error. When using the stylesheet_link_tag or javascript_include_tag helpers, I receive SyntaxError: [stdin]:1:1: missing /// .
