Question

Answer 1

A:

Pass the same parameter values back to the controller when the export button is clicked, send them back to the page as "listParams"

[ bookInstanceList: Book.list( params ), listParams: params ]

I might also suggest that you have a different action handle the click on the export button since you really do not want to list the data, you want to export it.

The formats tag supports the following attributes and allows you to pass through HTML attributes:

formats (Formats which should be displayed, List of Strings, e.g. ['csv', 'excel', 'ods', 'pdf', 'rtf', 'xml'])
params (Additional request
parameters, Map, e.g. [sort:params?.sort, order: params?.order])
action (Action which should be called, defaults to current action)
controller (Controller which should be called, defaults to current controller)

<export:formats params="${listParams}"/>

your date format in incorrect now, that is why you are getting the exception.

Aaron Saunders 2010-09-07 23:06:31

Yes...but how do I correct that?? I mean below is the way I am passing the parameters and in this , date is passed in that format.Below is the way I have written the parameters. <export:formats formats="['excel']" , params="[empId:params?.empId, empName: params?.empName, empDt: params?.empDt]" />

Aaron Saunders 2010-09-07 23:44:09

Thx Aaron. Is there a way I can do the format changes in my controller? When I use the <g:format> tag in my gsp, I am getting errors. Below is the code that i wrote in my gsp. This is the code in my list gsp that displays all the data in table format. The code is <h3> Download to: </h3>  <export:formats formats="['excel']" , params="[empId:params?.empId, empName: params?.empName, empDt: params?.empDt]" />

Megs 2010-09-08 00:01:46

use the same format code from before in your controller

Aaron Saunders 2010-09-08 00:07:37

You mean use <g:formatDate format="yyyy-MM-dd" date="${date}"/>in my controller list action??

Megs 2010-09-08 00:10:55

Could you please let me know what I should write to use the same format code??

Megs 2010-09-08 00:22:26

Here in my code <export:formats formats="['excel']" , params="[empId:params?.empId, empName: params?.empName, empDt: params?.empDt]" /> the empDt is passed as a String. Is there a way that I can convert this to a date before Firing the export?

Megs 2010-09-10 20:51:50

use <g:formatDate format="yyyy-MM-dd" date="${date}"/> to convert date to appropriate string format in the gsp

Aaron Saunders 2010-09-10 21:17:14

This is what I have in my list.gsp now. But I still get a String format .Please advice. <export:formats formats="['excel']" , params="[empId:params?.empId, empName: params?.empName, empDt: params?.empDt]" /> <g:formatDate format="yyyy-MM-dd" date="${empDt}"/>Am I doing something wrong here?

Megs 2010-09-10 21:46:58
