My tip this morning about the TOP attribute on the cfdump tag has been pretty popular, which makes me wonder what else people don't know about the cfdump tag. In ColdFusion 7 it was just a variable, a label, top, and whether the dump was expanded or not. ColdFusion 8 added the show, format, hide, keys, metainfo, output, and showUDFs attributes.
New ColdFusion 8 cfdump attributes
- format: Use with the output attribute to specify whether to save the results of a cfdump to a file in text or HTML format.
- hide: For a query, this is a column name or a comma-delimited list of column names. For a structure, this is a key or a comma-delimited list of keys.
- keys: For a structure, the number of keys to display.
- metainfo: For use with queries only. Includes information about the query in the cfdump results, including whether the query was cached, the execution time, and the SQL. You must specify metainfo="no" to exclude this information from the query result.
- output: Where to send the results of cfdump. The following values are valid: browser, console, filename (the full file path of the file that should be written).
- show: For a query, this is a column name or a comma-delimited list of column names. For a structure, this is a key or a comma-delimited list of keys.
- showUDFs: "yes" includes UDFs, with the methods collapsed, "no" excludes UDFs.
I use the format, show, and showUDFs all the time. The LiveDocs are your friend. Read all of that and more at the cfdump page in the ColdFusion 8 LiveDocs.
I do a lot of cfdumps with queries, but always forget to use the top attribute introduced in ColdFusion 8. You can use the top attribute to dump just the top x number of records from your query. When dealing with a wide query 500 rows, dumping the first 10 will give me more than enough information to do what I need to do, without waiting for the browser to finish rendering a huge dump table.
