我需要制作一个按钮来销毁对象。 而不是销毁它显示字段
inex.html.erb
<%= link_to image_tag("/images/glossy_green_button.png"), device , { :html => { :method => :delete}, :controller => :devices, :action => 'destroy',:id => device.id, :onclick => 'return confirm(\'Are you sure?\');' }, :method => :turnon %>
devices_controller.rb
def destroy
@device = Device.find(params[:id])
@device.destroy
respond_to do |format|
format.html { render action: "destroy" }
format.json { head :no_content }
end
end
的routes.rb
device GET /devices/:id(.:format) devices#show
PUT /devices/:id(.:format) devices#update
DELETE /devices/:id(.:format) devices#destroy
欣赏我的错误。 谢谢 d
更新:
<%= button_to "Delete", device , :method => :delete %>
这很好用

您使用的是哪个版本的Rails?为什么link_to
方法调用如此复杂?它可以简单地重写。请尝试以下方法:
<%= link_to image_tag("/images/glossy_green_button.png"), device , :method => :delete, :confirm => "Are you sure?"

破坏性操作应作为表单提交执行 - http://www.w3.org/2001/tag/doc/whenToUseGet.html#checklist
使用button_to(传递::方法:删除),并适当地设置按钮的样式。
或试试这个<%= button_to "delete", your_object, :method=>:delete, :class=>:destroy %>
