i have made an external method to connect and get data from an sql server 2000, and then show them in a table. All works fine but one of the columns i retrieve is a BLOB image witch makes my external method to crash. So i used z SQL Method (witch is not prefared because there is a lot of customization and that's why i used External Method with Python from the begining) and it goes fine with retrieving and showing the data. But still i cannot show the BLOB image as image. It shows as a very very long string.
You will need to do at least one query for the data and one request for each of the images. eg, you "main method" returns html like: <table> <tr> <th> Name </th> <th> Picture </th> </tr> <tr> <td> Test User </td> <td> <img src="http://localhost:8080/myproject/getImage?id=1231"/> </td> </tr> </table> You then need to implement getImage to: - do the SQL select to get the image data based on the id - write this data to the RESPONSE object (see lib/python/OFS/Image.py's index_html method for an example) - set a content-disposition header so that the browser does the right thing Hopefully soon you'll realise the fundamental issue with http that you're bumping into: you don't return a fully rendered page, you return a page with references in it to css/javascript/image files that are used to render the final page, and that storing binary data in relational databases is evil ;-) Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
