plugin_new_generator fails in `template': undefined method `today' for Date:Class (NoMethodError)

Reported by Steve Hodgkiss | March 4th, 2011 @ 11:18 AM | in 3.1


Using rails master and gems installed from rake install I tried to create a new mountable plugin with rails plugin new engine_test --mountable and the following error appeared.

active_support/time needs to be required for it to work.

    I think this has been inadvertently solved by recent commits. I've seen the issue (had it just happen with a slightly old local install of 3.1.beta) but after going through things with a cleanly built gemset, no more errors.

    FWIW, you can also just require 'date' to get it to pass, if we do want to specifically add in a fix and not just rely on whatever else it was that changed it. Also, you might need to do "rvm gemset create engine_test; rvm use 1.9.2-p136@engine_test" depending on your version of rvm.

    Course, as soon as I click submit and try it for real, busted again, as well as a different issue. Will look at it further, but either way, more eyes should take a look at this.

    Just tried it again on master, this is still an issue for me.

    Jack - you're right, require 'date' is all that is needed to fix this.

    Yep, tried it again, definitely still an issue. Found another one though--will open in a new ticket.

    I had the exact same issue. Running

    rake all:install

    resolved the problem.

    Err, that was for the "ERROR: Could not find a valid gem 'pkg/rails-3.1.0.beta.gem' (>= 0) in any repository" problem. Sorry.
