1.下載
fckeditor_plugin-0.3.2.zip，目前版本為0.3.2
2.解壓到vendor\plugins目錄下，并且重新命名為fckeditor
3.到該應(yīng)用程序根目錄下，然后運(yùn)行rake fckeditor:install，則執(zhí)行自動(dòng)安裝
4.在自己的view層中添加
<%= javascript_include_tag :fckeditor %>
以及在你需要編輯的字段textarea替換為
<%= fckeditor_textarea("book", "desc", { :toolbarKit => 'Simple', :width => '100%', :height => '200px' }) %>
第一個(gè)參數(shù)為你的domain對(duì)象，desc為你的編輯字段值，其他顧名思義
然后運(yùn)行你的頁(yè)面程序，發(fā)現(xiàn)simple upload有點(diǎn)bug，上傳后javascript報(bào)錯(cuò)
5.追蹤代碼發(fā)現(xiàn)
vendor\plugins\fckeditor\app\controllers\fckeditor_controller.rb下的
??def?upload
????self.upload_file
??end調(diào)用了upload_file方法
def?upload_file
????@new_file?=?params[:NewFile]
????@url?=?upload_directory_path
????begin
??????ftype?=?@new_file.content_type.strip
??????if?!?MIME_TYPES.include?(ftype)
????????@errorNumber?=?202
????????puts?"#{ftype}?is?invalid?MIME?type"
????????raise?"#{ftype}?is?invalid?MIME?type"
??????else
????????path?=?current_directory_path?+?"/"?+?@new_file.original_filename
????????File.open(path,"wb",0664)?do?|fp|
??????????FileUtils.copy_stream(@new_file,?fp)
????????end
????????@errorNumber?=?0
??????end
????rescue?=>?e
??????@errorNumber?=?110?if?@errorNumber.nil?
????end
????
????#?Fix?provided?by?Nicola?Piccinini?--?http://superfluo.org
????render?:text?=>?%Q'<script>window.parent.frames[\'frmUpload\'].OnUploadCompleted(#{@errorNumber});</script>'
????#render?:inline?=>?'page?<<?"window.parent.frames[\'frmUpload\'].OnUploadCompleted(#{@errorNumber},?\'#
{@new_file}\');"',?:type?=>?:rjs
??end 中的
render?:text?=>?%Q'<script>window.parent.frames[\'frmUpload\'].OnUploadCompleted(#{@errorNumber});</script>' 在瀏覽服務(wù)器時(shí)是正常的，但是在快速上傳中不應(yīng)該返回這個(gè)script語(yǔ)句
則修改upload方法
def?upload
????@new_file?=?params[:NewFile]
????@url?=?upload_directory_path
????begin
??????ftype?=?@new_file.content_type.strip
??????if?!?MIME_TYPES.include?(ftype)
????????@errorNumber?=?202
????????puts?"#{ftype}?is?invalid?MIME?type"
????????raise?"#{ftype}?is?invalid?MIME?type"
??????else
????????path?=?current_directory_path?+?"/"?+?@new_file.original_filename
????????File.open(path,"wb",0664)?do?|fp|
??????????FileUtils.copy_stream(@new_file,?fp)
????????end
????????@errorNumber?=?0
??????end
????rescue?=>?e
??????@errorNumber?=?110?if?@errorNumber.nil?
????end
????
????#?Fix?provided?by?Nicola?Piccinini?--?http://superfluo.org
????render?:text?=>?%Q'<script>window.parent.OnUploadCompleted(#{@errorNumber},\"#{UPLOADED}/#{params[:Type]}\",\"#{@new_file.original_filename}\",\"\");</script>'
??end 快速上傳問(wèn)題修復(fù)
6.發(fā)現(xiàn)文件夾里邊如果上傳圖片過(guò)多不好備份，故采用/年/月方式保存
修改代碼如下：
???def?upload
????@new_file?=?params[:NewFile]
????@url?=?upload_directory_path
????begin
??????ftype?=?@new_file.content_type.strip
??????if?!?MIME_TYPES.include?(ftype)
????????@errorNumber?=?202
????????puts?"#{ftype}?is?invalid?MIME?type"
????????raise?"#{ftype}?is?invalid?MIME?type"
??????else
????????path?=?date_directory_path?+?"/"?+?@new_file.original_filename
????????File.open(path,"wb",0664)?do?|fp|
??????????FileUtils.copy_stream(@new_file,?fp)
????????end
????????@errorNumber?=?0
??????end
????rescue?=>?e
??????@errorNumber?=?110?if?@errorNumber.nil?
????end
????
????#?Fix?provided?by?Nicola?Piccinini?--?http://superfluo.org
????render?:text?=>?%Q'<script>window.parent.OnUploadCompleted(#{@errorNumber},\"#{UPLOADED}/#{params[:Type]}/#{Time.now.year}/#{Time.now.month}/#{@new_file.original_filename}\",\"#{@new_file.original_filename}\",\"\");</script>'
??end?
??private
??def?date_directory_path
????base_dir?=?"#{UPLOADED_ROOT}/#{params[:Type]}/#{Time.now.year}/#{Time.now.month}"
????#Dir.mkdir(base_dir,0775)?unless?File.exists?(base_dir)
????FileUtils.mkdir_p?base_dir
????"#{base_dir}"
??end
7.同理可以對(duì)其上傳文件名稱(chēng)進(jìn)行隨機(jī)處理以防重名，就不多說(shuō)了。
做此筆記，拋磚引玉。
發(fā)現(xiàn)rails的plugin機(jī)制挺不錯(cuò)的，比較靈活，不過(guò)網(wǎng)上介紹plugin的文章真的不是很多
