关于视图：Rails的同一页面上有两种用于不同控制器的表单

Two forms for different controllers on same page in rails

更新：

下面的问题源于具有before_filter来验证用户身份。

我在同一页面上有两个表单，两个不同的form_for都有不同的模型。它们如下，并且都在devise / sessions / new视图中：

1

%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'

尽管在betasignup表单中输入新电子邮件时，它并没有像在views / beta_sign_ups / new视图中具有相同表单时那样保存到数据库中。为什么是这样？我需要对其中一个控制器或路由做些什么？

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表单的html输出：

<form accept-charset="UTF-8" action="/beta_sign_ups" class="new_beta_sign_up" id="new_beta_sign_up" method="post"><input name="utf8" type="hidden" value="a?""><input name="authenticity_token" type="hidden" value="K4wlzIZ958PdaC91vV4NMu4PLm3TF+yVebN0ll2VuoI=">

<label for="beta_sign_up_email">Your Email:</label>
<input id="beta_sign_up_email" name="beta_sign_up[email]" size="30" type="text">

<input name="commit" type="submit" value="Submit">

</form>

提交到betasignups表单后，服务器的输出将记录为日志：
