After that you must turn both modules of Downloader on in WebAdmin/plugins: the Downloader is dependent on WebAdmin plugin. And finally you need to get apply the permissions of Downloader to the users. In this case if you like to use !PyCaptcha, you must install it yourself, !PyCaptcha is dependent on Python Imaging Library (PIL) so you must download it too. '''Using source''' - installation with !PyCaptcha and PIL which are needed for Captcha to work: {{{#!sh easy_install --find-links http://www.pythonware.com/products/pil/ Imaging easy_install PyCaptcha easy_install https://trac-hacks.org/svn/tracdownloaderplugin/0.10/ }}} '''Second and maybe better way''' is to download and unpack somewhere source zip package and then just run "setup.py install" (or on Windows maybe better "python setup.py install") or you can just use easy_install commands written above. ~~Setup should take care of all dependences (!PyCaptcha and PIL but it could get some errors while dowloading them so if automatic dependency resolution doesn't work use code above) and prepare plugin to be turned on in !WebAdmin/plugins.~~ Setup just installs TracDownloaderPlugin. If you like to use Captcha tests you have to install PIL and !PyCaptcha manually either (note that PIL is in most ''Linux distributions'' package named '''python-imaging''' so you don't need to install it by easy install but you can use your package manager). Then you must enable both Downloader modules in !TracAdmin/Plugins (or enable Downoader components in your envronment's `trac.ini` file - source bottom) and assign some permissions of downloader to someone and you can start trying Downloader plugin: {{{#!ini [components] tracdownloader.admin.downloaderadminpage = enabled tracdownloader.web_ui.downloadermodule = enabled }}} After the steps above and clicking to any part of Downloader you should be asked about location of directory to store uploaded files. When it is set up, you must Submit that form two times and there can occur exception "!DatabaseError: database schema has changed". If this exception is thrown, it is best to restart your http server. Downloader keeps using '''!ClearSilver''' as templating system so you have to have it installed (version for new templating system Genshi will be written soon). '''Version for Trac 0.11 wasn't too much tested so if you find errors, please write me a ticket.''' '''If you had problems installing Downloader, please write me a ticket or write solution of your installation problems here.''' == Permissions Downloader plugin defines the following permissions: `DOWNLOADER_DOWNLOAD`: lets user to download things from main part of plugin, if you like to let all users download from donwloader, just get this permission to user anonymous. `DOWNLOADER_STATS`: lets user to browse part of statistics in the main module of Downloader (user will be able to see links to statistics in the right top corner of the page). `DOWNLOADER_ADMIN`: lets user to upload files, manage files, releases and categories, browse fill up's of questionnaire, delete fill up's of questionnaire and manage settings of Downloader plugin. Note that this permission should never be given to user anonymous! == Wiki syntax Downloader plugin provides three types of wiki syntax for referencing of standalone files, whole releases or categories. Each syntax has two possible forms. If syntax is enclosed by [] you can easily write your own title for item (file, release, category). If the syntax is separated just by spaces, there will be automatically created link with name of referenced item (file, release, category). '''Syntaxes:''' {{{ downloader:5 - Creates link to file with id 5 with it's name [downloader:5 click here] - Creates 'click here' link to file with id 5 downloaderrel:23 - Creates link to release with id 23 with it's name [downloaderrel:23 click here] - Creates 'click here' link to release with id 23 downloadercat:43 - Creates link to category with id 43 with it's name [downloadercat:43 click here] - Creates 'click here' link to category with id 43 }}} If item of that id doesn't exist, there is diplayed a dead link with title "id not found". If the file was deleted, it still displays its correct name, but does not link to anywhere. == Special features This features are available only if you have Downloader installed in unzipped form. This doesn't work in egg or zip file. '''MIME list''' In tracdownloader directory there is a file mime_list.txt which contains list of known MIME types for downloader, you can easily add new ones or delete unneeded, if there is no record found for particular file extension in this list, Downloader uses MIME of application/octet-stream. '''EDIT QUESTIONNAIRE''' The file form_data.py contains the structure used to generate questionnaire before the download of the file. You can easily edit this to get from users the data you want. There is big description inside of this file. == Reset all statistics To clear all recorded data about downloads and users who downloaded anything by !DownloaderPlugin you can use on your Trac environment database these two SQL commands. {{{#!sql DELETE FROM downloader_downloaded_attributes; DELETE FROM downloader_downloaded; }}} After this '''all statistics are gone'''. == Recent Changes [[ChangeLog(tracdownloaderplugin, 3)]] == Author/Contributors '''Author:''' [wiki:peca Petr Škoda] [[BR]] '''Maintainer:''' [[Maintainer]] [[BR]] '''Contributors:'''
