rails-form_tag-lab-v-000-源码
Rails form_tag实验室
目标
使用form_tag构建功能性的Rails表单
将路由助手作为参数传递给form_tag
将带有方法的选项散列传递给form_tag
使用text_field_tag和其他表单控件来创建输入
构建一个new动作，该动作将呈现一个提交给create动作的表单
指示
该实验室当前失败的两个规格位于specs/features/student_spec.rb的form page功能内。
在本实验中，您需要构建一个表单来创建一个新学生，将表单重定向回到new视图模板（通常， create操作会将其重定向到index ），然后将表单参数打印到屏幕上。 以下是一些要记住的事项：
绘制一个new并为students资源create路线
将学生值打印到视图模板页面
要记住的关键
查看测试以查看您应该使用哪些字段值
确保使用form_tag帮助器
