Question

此时我已多次执行命令heroku run rake db:migrate，这不是我遇到的问题。

我的应用程序在localhost上完美运行，但是当我部署到Heroku时，我的/ guestbooks页面收到来自Heroku日志的500错误。

我运行了rake db：reset然后删除了我的测试数据库记录，认为我的数据库可能需要从测试到生产干净，但这不起作用。我然后运行heroku运行rake db：再次迁移无济于事。该应用程序仍适用于localhost

以下是我的MVC和路线。我想知道是否有人发现可能导致问题的任何事情。我被卡住了......

控制器

class GuestbooksController < ApplicationController
    before_action :load_page

    def index
        @guestbook = Guestbook.new
    end

    def create
        @guestbook = Guestbook.new(guestbook_params)

        if @guestbook.save
            flash.now[:notice] = "Thanks for taking the time to write us! We greatly appreciate it!"
            render :new
        else
            flash.now[:notice] = "Your message failed to post, please try again"
            render :new
        end
    end

    private

    def load_page
        @guestbooks = Guestbook.page(params[:page])
    end

    def guestbook_params
        params.require(:guestbook).permit(:name, :email, :message)
    end
end

模型

class Guestbook < ActiveRecord::Base
    paginates_per 5
end

查看

<div class="paginate">
    <%=paginate @guestbooks%>
</div>

<div class="span1">
    <% @guestbooks.each do |g| %>
        <br/>
        <h4><%= g.name %>, <%= g.created_at %><br/></h4>
        <%= g.message %><br/>
        <p>-----------------------------------------------------------------------------------------------------------------------</p>
    <% end %>
</div>

<%= simple_form_for @guestbook, url: guestbooks_path, method: :post do |f| %>
    <div class="span2"><%= f.input :name %></div>
    <div class="span2"><%= f.input :email %></div>
    <div class="span3"><%= f.input :message %></div>
    <div class="span4"><%= f.button :submit %></div><br/><br/><br/>
<% end %>

resources :guestbooks, only: [:create, :index]
