Question

部署到Heroku后出现问题。试图访问/ sign_ups / new我在日志中看到了这一点。

但是，如果我在heroku上运行rake路由，我会看到这一点。

  referrals GET  /r/:id(.:format)        sign_ups#referral
   sign_ups POST /sign_ups(.:format)     sign_ups#create
new_sign_up GET  /sign_ups/new(.:format) sign_ups#new
    sign_up GET  /sign_ups/:id(.:format) sign_ups#show
       root      /                       sign_ups#new

即使在作为生产模式运行时，一切都在本地运行良好。我缺少什么想法？

sign_ups_controller.rb

class SignUpsController < ApplicationController
  def new
    @sign_up = SignUp.find_by_remember_token(cookies[:remember_token])
    if @sign_up.nil?
      @sign_up = SignUp.new
    else
      render :show
    end
  end

  def create
    @sign_up = SignUp.new(params[:sign_up])
    if @sign_up.save
      cookies.permanent[:remember_token] = @sign_up.remember_token
      flash[:notice] = 'Thanks for signing up!'
      redirect_to root_path
    else
      render action: "new"
    end
  end

  def referral
    @sign_up = SignUp.new
    render action: "new"
  end
end

sign_ups_helper.rb

module SignUpHelper
  def referral_link(referral_id)
    URI::join(root_url, referrals_path(referral_id))
  end
end

Answer 1

解决了这个问题。它与迁移有关。我在单独的迁移中添加了referral_id，但没有设置默认值。

Heroku - 没有路线匹配
