当年写的博客：[redmine自定义长文本字段显示及导出pdf排版问题临时解决方案]（https://my.oschina.net/hexie/blog/142134）
问题介绍:因项目组2月底正式引进了redmine2.2.1管理从需求到开发到测试到上线的任务跟踪，近期又想将另一个数据变更系统的数据定时导入redmine来跟踪分发管理，以尽可能的避免丢失变更单的情况。 直接带来的一个问题就是自定义些许字段来放置数据变更单审批系统的数据，其中就牵涉到几个长文本字段。如：变更原因及内容、备份脚本、回滚脚本、变更脚本等；这些通过自定义类型为长文本的字段后即可使用，问题来了：
- 在issue现实页，自定义长文本字段混在自定义的字符串字段中，页面不好看；
- 在issue页导出pdf时，自定义的长文本字段又仅显示一行，自动隐藏溢出的字符；
附，当年查找参考过的链接：
修订render_custom_fields_rows(issue)函数；判断自定义的长文本字段不显示 新增render_custom_fields_rows2(issue)函数；判断如为自定义的长文本字段则显示；
def render_custom_fields_rows(issue)
return if issue.custom_field_values.empty?
ordered_values = []
half = (issue.custom_field_values.size / 2.0).ceil
half.times do |i|
ordered_values << issue.custom_field_values[i]
ordered_values << issue.custom_field_values[i + half]
end
s = "<tr>\n"
n = 0
ordered_values.compact.each do |value|
s << "</tr>\n<tr>\n" if n > 0 && (n % 2) == 0
#s << "\t<th>#{ h(value.custom_field.name) }:</th><td>#{ simple_format_without_paragraph(h(show_value(value))) }</td>\n"
if h(value.custom_field.name).include?"$"
#s << "\t<th>#{ h(value.custom_field.name) }:</th><td colspan=\"3\">#{ simple_format_without_paragraph(h(show_value(value))) }</td>\n"

end
n += 1
end
s << "</tr>\n"
s.html_safe
end
def render_custom_fields_rows(issue)
return if issue.custom_field_values.empty?
ordered_values = []
half = (issue.custom_field_values.size / 2.0).ceil
half.times do |i|

render_custom_fields_rows2(issue)函数
def render_custom_fields_rows2(issue)
return if issue.custom_field_values.empty?
ordered_values = []

if h(value.custom_field.name).include?"$"
s << "\t<p><strong><th>#{ h(value.custom_field.name) }:</th></p></strong></tr>\n<tr>\n<td colspan=\"3\"><pre>#{ simple_format_without_paragraph(h(show_value(value))) }</pre></td>\n"
end

end

s.html_safe
end
新增自定义长文本字段的展现在描述后
<% if @issue.description? %>
<div class="description">
<div class="contextual">
<%= link_to l(:button_quote), quoted_issue_path(@issue), :remote => true, :method => 'post', :class => 'icon icon-comment' if authorize_for('issues', 'edit') %>
</div>
<p><strong><%=l(:field_description)%></strong></p>
<div class="wiki">
<%= textilizable @issue, :description, :attachments => @issue.attachments %>
</div>
</div>
<% end %>
<% if @issue.description? %>
<div class="description">
<div class="contextual">
<%= link_to l(:button_quote), quoted_issue_path(@issue), :remote => true, :method => 'post', :class => 'icon icon-comment' if authorize_for('issues', 'edit') %>
</div>
<p><strong><%=l(:field_description)%></strong></p>
<div class="wiki">
<%= textilizable @issue, :description, :attachments => @issue.attachments %>
</div>
</div>
<hr />
<div class="description">
<div class="wiki">

代码1：修订自定义长文本字段不在属性里显示； 代码2：修订自定义长文本字段在描述后显示；
