Question

这是我的show.html.erb。

我只是尝试在另一个中使用if语句，如果提供商是Facebook使用特定网址，如果提供商是谷歌使用其他方法。

<% if current_user %>

  <%= if current_user.provider == 'google' %>
    <%= image_tag "#{current_user.image}?sz=100", style: "border-radius:50px" %>
  <% else %>
    <%= image_tag "https://graph.facebook.com/#{current_user.uid}/picture?width=60&height=60", style: "border-radius:50px" %>
  <% end %>

<%= current_user.name %>

<% else %>
  <%= link_to "Logar com o Facebook", "/auth/facebook", id: "sign_in", class: "btn btn-info" %>
  <%= link_to "Logar com o Google", "/auth/google_oauth2", id: "sign_in" , class: "btn btn-success" %>
<% end %>

但我收到此错误：

Facegoogle/app/views/home/show.html.erb:5: syntax error, unexpected ')', expecting keyword_then or ';' or '\n' ...ent_user.provider == 'google' );@output_buffer.safe_append=' ... ^

您不应该打印（mutable.Seq）Google的if语句

更改行：

List

要：

Vector

我使用if if inside时出错
