小编Abr*_*ram的帖子

以下查询的工作方式类似于魅力:

@styles = Style.search { fulltext params[:q] }

我遇到的问题是分页.这是与分页相同的查询:

@styles = Style.search { fulltext params[:q]; paginate :page => params[:page], :per_page => params[:page_limit] }

我有11 Style条记录.

如果我有:page => 1,:per_page => 10当我搜索第11条记录时,我会返回一个空数组@styles.results

如果我设置:page=>2并执行相同的搜索,我将获得第11个样式记录.

[11] pry(#<StylesController>)> params[:page]=2
=> 2
[12] pry(#<StylesController>)> x=Style.search {fulltext params[:q]; paginate :page => params[:page], :per_page => params[:page_limit] }
=> <Sunspot::Search:{:fq=>["type:Style"], :q=>"hel", :fl=>"* score", :qf=>"name_textp full_name_textp", :defType=>"dismax", :start=>10, :rows=>10}>
[13] pry(#<StylesController>)> x.results
=> [#<Style id: 15...>]

我认为重点是对搜索结果进行分页,而不是整个实际记录

这里发生了什么,我该如何解决？

编辑

好吧,让我试着用另一种方式解释.假设我有这六个记录:

1 => …

我有一个下拉框,我想在选择一个项目后锁定.不幸的是,使用"禁用"会在提交表单时停止提交字段.有没有解决的办法？

我试图按照这里的答案在地图上显示单个标记时缩小一点(默认情况下).我已经尝试了下面的代码,并生成了一个工作地图,但更改setZoom没有任何效果.此外,我从firebug收到以下错误(代码下方).

<%= gmaps("markers" => {"data" => @json, "options" => {"auto_zoom" => false} }) %>

<% content_for :scripts do %>
    <script type="text/javascript" charset="utf-8">
      function gmaps4rails_callback() {
        if (Gmaps4Rails.markers.length == 1) {
         //only one marker, choose the zoom level you expect
         Gmaps4Rails.map.setZoom(5);
        }
        else{
         //more than one marker, let's auto_zoom
         Gmaps4Rails.map_options.auto_zoom = true;
         Gmaps4Rails.adjust_map_to_bounds();
        }
      }
    </script>
<% end %>

唯一的错误是:

TypeError: Yc is not a function
[Break On This Error]   

...=b}Rf[F].Fa=xk(7,Yc("f"));me[F].cb=xk(3,function(a){var b;if(b=a.ca[ec]()?j:a.ca...

嗨,我想做以下工作:

http://localhost:3000/reviews/new?ticket[]=token[]=109u11

它可以被认为是意义 params[:ticket][:token] = 109u11

谢谢!

我收到以下错误:

  undefined method `can_read?' for nil:NilClass

..当试图访问已注销用户的产品页面时.目前我有

class ProductAuthorizer < ApplicationAuthorizer

  def self.readable_by?(user)
    true
  end

end

我想允许甚至未登录的用户查看该页面.这可能吗？

我尝试将默认用户方法更改为:

config.user_method = :current_user ||= User.new

但是,这会导致问题,我的服务器甚至都无法启动.

在我的控制器中,如果用户已退出,我将重定向用户.然后我拉了一个专业人员列表..如果不存在,也需要重定向.有没有办法解决这个难题？

  def purchase
    @style = Style.find(params[:id])
    if user_signed_in? && current_user.consumer 
      @professionals = Professional.where(...)
      if @professionals.empty?
        redirect_to style_path(@style)
      else
        ...
      end
      ...
    else
      flash[:error] = "Please sign in as a consumer to access this page"
      redirect_to style_path(@style)
    end
  end

在 Gmail 中，以下电子邮件地址

class UserMailer < ActionMailer::Base
  default from: 'no-reply@example.com'
end

变成这个（第二项）

无论如何让“发件人”地址为“无回复”但发件人名称更有意义吗？

我注意到我的电子邮件表单 SumAll 呈现为来自“SumAll”，但对地址的回复不同，如下所示：

From: =?utf-8?Q?SumAll?= <mailing@sumall.com>

知道如何使用 Action Mailer 管理这个吗？

这是我以前在Rails 3中使用过的表单:

<%= form_for Style.new do |s| %>
<% end %>

抛出错误: nil的未定义方法`param_key':NilClass

我正在尝试使用Select2 jquery插件进行AJAX调用.查询似乎有效,但.results()在options对象上调用时会出现问题:

Uncaught TypeError: options.results is not a function

这是我的HTML:

<input class="form-control" type="number" value="2125" name="topic_relation[source_topic_id]" id="topic_relation_source_topic_id" />

这是我的JS:

$(document).ready(function() {
  $('#topic_relation_source_topic_id').select2({
    minimumInputLength: 3,
    ajax: {
      url: "<%= grab_topics_path %>",
      dataType: 'json',
      delay: 250,
      data: function (term, page) {
        return {
          q: term, //search term
          page_limit: 30, // page size
          page: page, // page number
        };
      },
      processResults: function (data, page) {
        var more = (page * 30) < data.total;
        return {results: data.topics, more: more};
      }
    }, …
