Question

嗨，我在建筑物周围做了一个简单的RoR应用程序，并遇到以下问题：我创建了一个名为“Credit”的Scaffold，以及User和Credit模型之间的关系：这是我的文件

credit.rb

class Credit < ActiveRecord::Base
attr_accessible :amount, :user_id
belongs_to :user
belongs_to :merchant

end

user.rb

class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me,
                :first_name, :last_name, :profile_name 

# attr_accessible :title, :body
has_many :statuses
has_many :merchants
has_many :credits

def  full_name
first_name + " " + last_name
end
end

尝试使用以下格式创建新的信用条目时：

<%= simple_form_for(@credit) do |f| %>
<%= f.error_notification %>

<div class="form-inputs">
 <%= f.input :amount %>
 <%= f.input :user_id, collection: User.all %>

</div>


<div class="form-actions">
 <%= f.button :submit %>
</div>
<% end %>

我收到以下错误

Credits中的NoMethodError＃new

显示/ Users / andreucasadella / rails_projects / monedero / app / view credits / _form.html.erb第6行引发：

＃

的未定义方法`user_id'

有什么想法吗？

积分中的RoR NoMethodError＃new
