如果找到邀请,用户不得指定电子邮件。我这样做了,对吧?
是否可以避免代码重复?
<% if @invitation %>
<%= f.email_field :email, class: 'form-control', placeholder: t('.placeholder.email'), value: @invitation.email %>
<% else %>
<%= f.email_field :email, autofocus: true, class: 'form-control', placeholder: t('.placeholder.email') %>
<% end %>

你可以在没有条件的情况下这样做:
f.email_field :email, class: 'form-control', placeholder: t('.placeholder.email'), value: @invitation && @invitation.email, autofocus: !@invitation

有点难以阅读,但您可以合并您的选项:
<% f.email_field(:email, {class: 'form-control', placeholder: t('.placeholder.email')}.merge(@invitation ? {value: @invitation.email} : {autofocus: true})) %>
