缘由：由于manager的错误设置，导致本不该public的项目设置成public
诉求：去除项目新建及设置时的public勾选
1、查找日志
由于redmine是拿ruby编写的，且主页等都是由html.erb生成的，查找源码比较麻烦，该选项为“Public”，对应源码里有很多混淆项。基于此，考虑去看一下log。
查看日志并保持窗口：tail -f -n 100 production.log
我们将某个无关紧要的项目设置成public并立即设置成non-public。观察上述日志的变化。
在查看日志的时候，发现有一个字段“is_public”如下：
./production.log: Parameters: {"utf8"=>"✓", "authenticity_token"=>"I2u5UTstAZCtEHOuXzNhMn005kbHxaaFMlYohspiqM+STGLxily+xgBmdjvlbyeYsmp9yjPGGYFK/wBMY0X/4Q==", "project"=>{"name"=>"*****", "description"=>"", "homepage"=>"", "is_public"=>"1", "parent_id"=>"262", "inherit_members"=>"0", "custom_field_values"=>{"35"=>"125", "36"=>"", "37"=>"", "38"=>"", "39"=>"", "40"=>"Team management Project"}, "agile_color_attributes"=>{"color"=>""}, "tracker_ids"=>["1", "2", "3", ""], "issue_custom_field_ids"=>[""]}, "commit"=>"Save", "id"=>"*****"}
可以看见 "is_public"=>"1" ，对应的取消public设置时该字段为"is_public"=>"0"，可见源码中存在该“is_public”字段的设置。
2、查找源码字段
在redmine源码根目录查找：
$ find . -name *.erb |xargs grep "is_public"
./app/views/admin/projects.html.erb: <th><%=l(:field_is_public)%></th>
./app/views/admin/projects.html.erb: <td><%= checked_image project.is_public? %></td>
./app/views/projects/_form.html.erb:<p><%= f.check_box :is_public %></p>
./plugins/redmine_agile/app/views/agile_queries/_form.html.erb: <p><label for="query_is_public"><%=l(:field_is_public)%></label>
./plugins/redmine_agile/app/views/agile_queries/_form.html.erb: <%= check_box 'query', 'is_public',
./plugins/redmine_agile/app/views/agile_queries/_form.html.erb: :disabled => (!@query.new_record? && (@query.project.nil? || (@query.is_public? && !User.current.admin?))) %></p>
可见以上三个文件文件中有对应字段，其中redmine_agile是插件，如果没有安装则无需修改。
3、修改源代码
修改三个文件的源码，请先做好文件备份工作！删除以下内容：
app/views/admin/projects.html.erb <th><%=l(:field_is_public)%></th>
<td><%= checked_image project.is_public? %></td>
app/views/projects/_form.html.erb <p><%= f.check_box :is_public %></p>
plugins/redmine_agile/app/views/agile_queries/_form.html.erb<p><label for="query_is_public"><%=l(:field_is_public)%></label>
<%= check_box 'query', 'is_public',
:onchange => (User.current.admin? ? nil : 'if (this.checked) {$("#query_is_for_all").removeAttr("checked"); $("#query_is_for_all").attr("disabled", true);} else {$("#query_is
_for_all").removeAttr("disabled");}') %></p> <p><label for="query_is_for_all"><%=l(:field_is_for_all)%></label>
<%= check_box_tag 'query_is_for_all', 1, @query.project.nil?,
:disabled => (!@query.new_record? && (@query.project.nil? || (@query.is_public? && !User.current.admin?))) %></p>
修改后无需重启apache2，但如需恢复public选项，则请覆盖被修改文件，重启apache2。
