我试图评估3条件以了解应该呈现什么按钮。代码是:
<% if action == "edit" %>
<%= link_to '<button type="button" class="btn btn-warning"><i class="fa fa-reply"></i> Volver</button>'.html_safe, customers_path %>
<%= button_tag(type: 'submit', class: "btn btn-success") do %>
<i class="fa fa-floppy-o"></i> Guardar
<% elsif action == "show" %>
<!--<%= link_to '<button type="button" class="btn btn-default"><i class="fa fa-pencil"></i> Editar</button>'.html_safe, edit_customer_path(@customer) %>-->
<% elsif action == "new" %>
<%= link_to '<button type="button" class="btn btn-warning"><i class="fa fa-reply"></i> Volver</button>'.html_safe, customers_path %>
<%= button_tag(type: 'submit', class: "btn btn-success") do %>
<i class="fa fa-floppy-o"></i> Guardar
<% end %>
我收到以下错误:
/home/nando/gadmon/app/views/customers/_form.html.erb:62: syntax error, unexpected keyword_elsif, expecting keyword_end '.freeze; elsif action == "show" ^ /home/nando/gadmon/app/views/customers/_form.html.erb:64: syntax error, unexpected keyword_elsif, expecting keyword_end '.freeze; elsif action == "new" ^ /home/nando/gadmon/app/views/customers/_form.html.erb:76: syntax error, unexpected keyword_ensure, expecting keyword_end /home/nando/gadmon/app/views/customers/_form.html.erb:78: syntax error, unexpected end-of-input, expecting keyword_end
我试图添加&#34;结束&#34;如果,elsif或其他仍然无法正常工作。
问候。
答案 0 :(得分:2)
所有按钮需要&lt;%end%&gt;
<% if action == "edit" %>
<%= link_to '<button type="button" class="btn btn-warning"><i class="fa fa-reply"></i> Volver</button>'.html_safe, customers_path %>
<%= button_tag(type: 'submit', class: "btn btn-success") do %>
<i class="fa fa-floppy-o"></i> Guardar
<% end %>
<% elsif action == "show" %>
<!--<%= link_to '<button type="button" class="btn btn-default"><i class="fa fa-pencil"></i> Editar</button>'.html_safe, edit_customer_path(@customer) %>-->
<% elsif action == "new" %>
<%= link_to '<button type="button" class="btn btn-warning"><i class="fa fa-reply"></i> Volver</button>'.html_safe, customers_path %>
<%= button_tag(type: 'submit', class: "btn btn-success") do %>
<i class="fa fa-floppy-o"></i> Guardar
<% end %>
<% end %>
