A simplification of file creation
---------------------------------
Key: DISPL-325
URL: http://jira.codehaus.org/browse/DISPL-325
Project: DisplayTag
Type: New Feature
Components: Export
Versions: 1.1
Reporter: Howard Rafal
Attachments: useExtension.diff
We currently have about 30 different tables in our application which each can
export to csv, xml, excel, and pdf. We want to have each one export as a unique
name. This requires that each table set the four filename properties and if we
decide to add to the export, we need to change all 30 tables to add the new
filename. I have implemented and tested the following solution for this. Not
sure if it is the cleanest way to do this but essentially it boils down to:
2 export parameters:
export.use_extension=true
export.filename= <default generic filename>
If using extension, then this filename parameter is used for any export media
type and a specified extension is used for each media type by using, if
use_extension if false, then it behaves the original way:
export.<mediatype>.extension
So, I just had to add the following to my properties file:
export.excel.extension=xls
export.xml.extension=xml
export.pdf.extension=pdf
export.csv.extension=csv
This is nice (for our use) because our JSPs just defines export.filename once
and it works for all four of our media types and if we add more, we don't have
to touch our JSPs.
To implement this I just updated TableProperties.java. I attached the diff (I
added two constants and replaced the getExportFileName with my version).
Thanks for considering this.
