如果使用內部錯誤if

Question

這是我的show.html.erb。

我只是想在另一個if語句中使用if語句，當提供者是Facebook時使用特定的url，如果提供者是google使用另一種方法。

<% 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 %> 

，但我得到這個錯誤：

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=' ...^

你不應該打印（<%=）從if語句的谷歌

更改行：

<%= if current_user.provider == 'google' %> 

收件人：

<% if current_user.provider == 'google' %>
