Scaffold output: add jbuilder, update timestamp (edge guide!)
Add some file breadcrumb (comment) to help reader find files.
Improve readability by adding some command outputs.
Thanks for great help from @senny.
clarify that the contents of the block is expected to return a string. the previous example executed puts and the initializer got nothing.
also, made it consistent with the single-line example to be more clear as to what's going on
There's no reason for guides to reference old behaviors. They should
be current as of the versions of Rails that they ship with, and including
older information just clutters thing.
I discussed this change with @fxn and he agrees.
Change the default test locations to avoid confusion around the common
testing terms "unit" and "functional".
Add new rake tasks for the new locations, while maintaining backwards
compatibility with the old rake tasks.
New testing locations are as follows:
app/models -> test/models (was test/units)
app/helpers -> test/helpers (was test/units/helpers)
app/controllers -> test/controllers (was test/functional)
app/mailers -> test/mailers (was test/functional)
