One feature that will be part of PODAM next release is the possibility to
provide Strategies with metadata about the field being filled with data.
Then, in your case, you would be able to implement a custom strategy that
prepended the field name to the value. So, at a high-level, you would
compose your custom strategy with the default strategy and then you could
have:
return metadata.getField().getName() + "_" +
defaultStrategy.getRandomString();
Something like that.
What I can't tell you is when I will be releasing the next version. I'm very
busy at the moment but if anyone feels they could implement this
functionality fork the code, try it out and when ready issue a pull request.
Best,
Marco
