guys, i just want to use form_tag to update the db. 伙计们,我只想使用form_tag来更新数据库。 I got stucked by this error and have been searching for few hours. 我被这个错误困住了,已经搜索了几个小时。 Appreciated for all your help!!!!! 感谢您的所有帮助!!!!
Remove action => :create
from your form_tag declaration. 从form_tag声明中删除action => :create
。
Per your raked routes, the only route you have for a POST to resolve to dcrelations#create is to the URI /dcrelations(.:format)
根据您的倾斜路线,POST解析为dcrelations#create的唯一路线是URI /dcrelations(.:format)
