新手问题 用 form_for (@info) do |f| 提示 NoMethodError
结构是这样的：
在 views/info/create.html下面， 用 form_for(@info) do |f| 提示 NoMethodError
路由里映射过去了的啊。
match '/create_message', to: 'info#create', via: 'get'
然后我在 InfoController.rb 里也加了这个的
def create
@info = Info.new
end
如果不加 Info.new 就是 ArgumentError in Info，First argument in form cannot contain nil or be empty
求老司机指点迷津
NoMethodError in Info#create
Showing /home/coldfarmer/rubyprj/sharedinfo/app/views/info/create.html.erb where line #4 raised:
undefined method `infos_path' for #<#<Class:0xb4866488>:0xa25bfd4>
Extracted source (around line #4):
<div class="row">
<div class="span6 offset3">
<%= form_for(@info) do |f| %>
<%= f.label :content %>
<%= f.text_field :content %>
<%= f.submit "Create a Message" , class: "btn btn-large btn-primary" %>
