Question

更新：

下面的问题源于有一个对用户进行身份验证的before_filter。

我在同一页面上有两个表单，两个不同的form_for，每个表单都有不同的模型。它们如下所示，都在设计/会话/新视图中：

%h2 Sign in
= form_for(resource, :as => resource_name, :url => session_path(resource_name)) do |f|
  %div
    = f.label :email
    %br/
    = f.email_field :email
  %div
    = f.label :password
    %br/
    = f.password_field :password
  - if devise_mapping.rememberable?
    %div
      = f.check_box :remember_me
      = f.label :remember_me
  %div= f.submit "Sign in"
= render :partial => "devise/shared/links"

=form_for BetaSignUp.new do |f|
  .field
    = f.label :email, "Your Email:"
    = f.text_field :email
  .actions
    = f.submit 'Submit'

当输入新的电子邮件到betasignup表单时，它不会保存到数据库中，因为它在views / beta_sign_ups / new视图中具有相同的表单时。为什么是这样？我是否需要对其中一个控制器或路线做些什么？

beta_sign_ups_controller：

class BetaSignUpsController < ApplicationController
  def new
    @beta_sign_up = BetaSignUp.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @beta_sign_up }
    end
  end

  def create
    @beta_sign_up = BetaSignUp.new(params[:beta_sign_up])

    respond_to do |format|
      if @beta_sign_up.save
        format.html { redirect_to root_path, notice: 'Thank you for signing up.  You will be notified when we expand the beta group.' }
        format.json { render json: @beta_sign_up, status: :created, location: @beta_sign_up }
      else
        format.html { render action: "new" }
        format.json { render json: @beta_sign_up.errors, status: :unprocessable_entity }
      end
    end
  end
end

betasignups形式的html输出：

<form accept-charset="UTF-8" action="/beta_sign_ups" class="new_beta_sign_up" id="new_beta_sign_up" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"><input name="authenticity_token" type="hidden" value="K4wlzIZ958PdaC91vV4NMu4PLm3TF+yVebN0ll2VuoI="></div>
<div class="field">
<label for="beta_sign_up_email">Your Email:</label>
<input id="beta_sign_up_email" name="beta_sign_up[email]" size="30" type="text">
</div>
<div class="actions">
<input name="commit" type="submit" value="Submit">
</div>
</form>

服务器的输出在提交到betasignups表后记录：

Started POST "/beta_sign_ups" for 127.0.0.1 at 2012-05-10 11:36:17 -0400

你仍然可以使用before_filter，只需传递一些选项，这样它只会激活特定的动作，或者使用它替代skip_before_filter来表示你在表单中使用的任何控制器动作。
