完整错误

ArgumentError in Devise::Registrations#new wrong number of arguments (given 1, expected 0)

我将rails升级到5，这似乎请帮我解决Thanx：）

更新了视图/设计/注册/ new.html.erb

<%= form_for(resource, :as => resource_name, :url => user_registration_path, :html => {:class => 'form-horizontal' }) do |f| %>
  <%= devise_error_messages! %>

  <div class="inputs">
    <%= f.text_field :email, :autofocus => true, :input_html => { :autocomplete => "off" } %>
</div>

  <div class="actions">
    <%= f.submit "Sign up" %>
  </div>

Answer 1

更新

<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:class => 'form-horizontal' }) do |f| %>

与

<%= simple_form_for(resource, :as => resource_name, :url => user_registration_path, :html => {:class => 'form-horizontal' }) do |f| %>

Answer 2

根据您的路线，您有，

<强> user_registration POST /users(.:format)

这将 post 改为 /users ，这是 create 的行动> registration 即可。

所以表格应该是。

<%= form_for(resource, :as => resource_name, :url => user_registration_path) do |f| %>
        <%= devise_error_messages! %>

        <%= f.text_field :email %>
<%end %>

Devise中的ArgumentError :: Registrations＃new
