Hi there,

How do I use more than one feeder for single scenario?

I’m trying to follow example similar to here [[https://github.com/excilys/gatling/wiki/Feeders#what](https://github.com/excilys/gatling/wiki/Feeders#what)] to use multiple CSV files. But it’s not working for me… But exec can’t find field from classesFeed… I’m using 2.0.0-M2.

17:33:39.546 [ERROR] i.g.h.a.HttpRequestAction - No attribute named ‘fieldFromClass’ is defined

val teachersFeed = csv(“teachers.csv”)  
val classesFeed = csv(“classes.csv”)

val scn = {  
scenario(“Create Class”)  
.feed(teachersFeed)  
.repeat(1) {  
feed(classesFeed)  
.exec(  
createClass("${fieldFromTeacher}","${fieldFromClass}")  
)  
}  
}

Thanks,  
Nilesh

Is the first line of your CSVs the names of the columns?

e.g.:  
fieldFromClass,secondFieldFromClass  
foo,bar  
baz,zed  
etc,…

My2cents: you have trailing/heading spaces in your header names.

fieldFromClass,secondFieldFromClass // good

fieldFromClass ,secondFieldFromClass // bad

fieldFromClass,secondFieldFromClass ← trailing space, bad
