Is anyone familiar with overriding the values for  
FixtureReplacement.defaults\_file

I’ve reviewed the rspec testcases. Changing the defaults\_file on first  
initial request fails; as it tries to load the default file first  
“#{rails\_root}/db/example\_data.rb”, the remaining request will  
initialize the defaults\_file correctly with no errors.

The easy approach would be to modify the file which contains the  
defaults\_file setting in FixtureReplacement.

Is this the rails way/best practices for overriding plugins.

Any ideas?

Thanks in advance
