Question

所以这个函数实际上可以在localhost上运行但是我遇到了heroku的问题。发生的情况是，用户点击用户的列表，点击应用，然后将电子邮件发送给列表用户。这适用于localhost但是当我在heroku中单击提交时，我收到错误。我在线查看并发现它经常连接到where子句，但我认为我没有where子句？

listings_controller.rb

def send_resume_email
        @listing = Listing.find_by(params[:id])
        @user = User.find_by(params[:id])
        UserMailer.new_resume(@user, @listing).deliver
        redirect_to findjobs_path, notice: 'Message sent'
    end

user_mailer.rb

 def new_resume(user, listing)
    @listing = listing
    @user = user
    @url = 'http://www.example.com'
    mail(to: listing.user.email, subject: 'Thanks for the awesome site')
end

apply.html.erb

<div class="top">
<div class="container-content">
    <div class="container">
        <%= form_tag(listing_send_resume_email_path) do %>
            <div class="form-group">
                <%= label_tag 'name', 'Name' %>
                <%= text_field_tag 'name', nil, class: 'form-control', placeholder: 'Your Name' %>
            </div>
           <div class="form-group">
               <%= label_tag 'email', 'Email' %>
               <%= email_field_tag 'email', nil, class: 'form-control', placeholder: 'Your Email Address' %>
           </div>
           <div class="form-group">
               <%= label_tag 'comments', 'Comments' %>
               <%= text_area_tag 'comments', nil, class: 'form-control', rows: 4, placeholder: 'Comments...' %>
           </div>
           <%= submit_tag nil, class: 'btn btn-default btn-about pull-right' %>
       <% end %>
  </div>
</div>
</div>

Answer 1

您错误地使用了find_by方法，请更改：

  def send_resume_email
    @listing = Listing.find_by(id: params[:id])
    @user = User.find_by(id: params[:id])
    UserMailer.new_resume(@user, @listing).deliver
    redirect_to findjobs_path, notice: 'Message sent'
  end

错误：错误：WHERE的参数必须是boolean类型，而不是类型integer
