我有一个rails 4应用程序,我正在尝试使用其中的字体真棒图标(用于社交媒体登录链接).

我有:

 /* application.css.css:
 *= require_framework_and_overrides.css.scss
 *= require_self
 *= require_tree .
 */

/* framework_and_overrides.css.css: */
@import "bootstrap-sprockets";
@import "bootstrap";
@import "font-awesome-sprockets";
@import "font-awesome";

在我的gemfile中:

gem 'font-awesome-sass', '~> 4.4.0'

我也在使用bootstrap sass.

在我看来,我尝试:

<%= link_to content_tag(icon('facebook', class: 'facebookauth')) %>

它呈现"<>>",两者之间没有任何内容.

我也尝试过:

<%= link_to content_tag icon('facebook', class: 'facebookauth') %>

我犯了同样的错误.

当我尝试:

<%= link_to content_tag(fa_icon('facebook', class: 'facebookauth')) %>
<%= link_to content_tag fa_icon('facebook', class: 'facebookauth') %>

我收到此错误:

undefined method `fa_icon' for

有谁知道如何在Rails中使用font-awesome？

新尝试:

                        <%= link_to  icon('google', id: 'googleauth'), user_omniauth_authorize_path(:google_oauth2) %>

                        <%= link_to icon('linkedin', id: …

我正在尝试在我的rails(4.0.0)项目中使用bootstrap-sass(3.1.0.2)和sass-rails(4.0.1).

我的application.css.scss文件如下所示:

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new …

我正在试图找出如何适应在Rails 4中使用的wrap bootstrap主题.

主题使用简单线图标.我试图将这些文件移动到我的app/assets文件夹中的字体文件夹,以及我的vendor/assets/css文件夹中的css文件和vendor/assets/javascript文件夹中的js文件夹.

我不明白如何重写css中的路径,以便以一种能够读取它们的方式引用资产.

例如,其中一个css文件包括以下内容:

@font-face {
  font-family: 'Simple-Line-Icons';
  src: url("../../fonts/Simple-Line-Icons.eot");
  src: url("../../fonts/Simple-Line-Icons.eot?#iefix") format("embedded-opentype"), url("../../fonts/Simple-Line-Icons.woff") format("woff"), url("../../fonts/Simple-Line-Icons.ttf") format("truetype"), url("../../fonts/Simple-Line-Icons.svg#Simple-Line-Icons") format("svg");
  font-weight: normal;
  font-style: normal;
}

我知道url(../ ..部分是rails的问题.我无法弄清楚的是如何解决它.

我在我的生产环境中安装了rails-12factor gem.我尝试了一百万种变化(在导轨指南中显示),但我找不到任何有用的东西.

谁能看到该怎么办？

本文建议不要在引用供应商资产字体文件中包含'fonts'文件夹.https://gist.github.com/iamatypeofwalrus/6467148

我已经尝试过包含和排除它,但两种方式都没有效果.

本文建议供应商文件无法在不修改初始化程序的情况下存储字体.我试过了,但它也没有用. 在Rails资产管道中使用字体

Rails.application.config.assets.paths

Heroku的

我现在发现这篇文章,这表明对于生产中的heroku合规性,我需要用资产路径助手替换所有内容并重命名文件以将.erb添加到images和css以及.coffee到js.在我这样做之前,有人可以确认这实际上是必需的,以及如何更改上述css文件以符合heroku要求.

我试图在我的rails 4 app中使用money-rails gem.

我有一个参与者模型,其中包含每个货币和participant_cost的属性.我的目标是让用户为每个实例指定一种货币,以及参与费用的金额.

在我的参与模型中,我有:

货币化:participation_cost,with_model_currency :: amount_currency

在我的表单中,我要求用户选择货币并指定金额,如下所示:

<%= f.input :participation_cost, label: 'What amount will you pay for participation costs?', :label_html => { :class => 'question-participants' }, placeholder: 'Whole numbers only', :input_html => {:style=> 'width: 250px; margin-top: 20px',  class: 'response-participants'} %>

<br><br>
<%= f.input :currency, label: 'Select your costs currency', label_html: {class: 'fundingspace'}, collection: ["AUD Australian Dollars", "GBP British Pounds", "USD US Dollars" ], prompt: "Choose one" %> </div> <br>

在我看来,我想显示货币和金额.我目前有一个字符串如下:

  <%=  "#{@project.scope.try(:participant).try(:participation_cost)} #{@project.scope.try(:participant).try(:currency)}" %>

当我测试这个时,我只得到参与号码的数字.我没有得到货币.

在我的money.rb初始化程序中,我有:

 config.default_currency …

我正在尝试在 Rails 4 中制作一个应用程序。我对表单使用简单的表单，对国家/地区列表使用 country_select gem。

我有一个地址模型，其中包括这个方法：

def country_name
    self.country = ISO3166::Country[country]
    country.translations[I18n.locale.to_s] || country.name
  end

当我尝试保存新地址时，出现此错误：

undefined method `translations' for "Australia":String

谁能看出这个方法定义有什么问题？

如果我将视图更改为：

<% if @profile.addresses.any? %>
        <%= @profile.addresses.first.country.titlecase %> 
    <% else %>
        <span class="profileeditlink">
            <%= link_to "Add your location", new_address_path %>
        </span>
    <% end %>   

然后记录显示 - 但显示为 AU 而不是澳大利亚（这是地址模型中提供的方法）。

地址表：

create_table "addresses", force: :cascade do |t|
    t.string   "unit"
    t.string   "building"
    t.string   "street_number"
    t.string   "street"
    t.string   "city"
    t.string   "region"
    t.string   "zip"
    t.string   "country"
    t.boolean  "main_address"
    t.boolean  "project_offsite"
    t.string …
