这可能是非常基本的,但我似乎无法弄清楚。
本质上,当我尝试使用表单创建新用户并且用户详细信息已经存在且不是唯一的时,我收到以下错误:
ArgumentError in UsersController#create
too few arguments
Application Trace | Framework Trace | Full Trace
app/controllers/users_controller.rb:61:in `format'
app/controllers/users_controller.rb:61:in `create'
这是我create
在我的行动user_controller.rb
:
# POST /users
# POST /users.xml
def create
@user = User.new(params[:user])
if @user.save
flash[:notice] = 'User successfully created' and redirect_to :action=>"index"
else
format.html { render :action => "new" }
format.xml { render :xml => @user.errors, :status => :unprocessable_entity }
end
end
end
这是我的user.rb
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :username, :password, :password_confirmation, :remember_me
validates :email, :username, :presence => true, :uniqueness => true
end
这也是我的表格:
<%= simple_form_for(@user) do |f| %>
<div class="field">
<%= f.input :username %>
</div>
<div class="field">
<%= f.input :email %>
</div>
<div class="field">
<%= f.input :password %>
</div>
<div class="field">
<%= f.input :password_confirmation %>
</div>
<div class="actions">
<%= f.button :submit %>
</div>
<% end %>
