dm-core 1.0.0 breaks sinatra app.

Reported by Ian Alexander Wood | June 8th, 2010 @ 03:08 PM

Hi there. After updating to dm-core 1.0.0 Datamapper no longer recognises SQlite3!

Here's the error when trying to launch a simple SQlite3 based sinatra app:

/Users/i0n/.rvm/rubies/ruby-1.8.7-p174/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in gem_original_require': no such file to load -- sqlite_adapter (LoadError)

    • State changed from “new” to “not-applicable”

    @Ian: You need to install the dm-sqlite-adapter, and possibly dm-migrations if you use auto-migrations at all.

    See the release notes for more information on this:

    Hi

    I was having the same problem that Ian had doing SQlite3 based sinatra app, and it passed when I installed sqlite_adapter but then I got (with dm-migrations installed)

    I'm using DataMapper 1.0. I am pretty new on this. I am doing an app testing to see if I can build a reporting app with DataMapper. Maybe, I'm doing something wrong but I thought it'd be helpful

    Here is my gem list,

    dm-aggregates (1.0.0)
    dm-constraints (1.0.0)
    dm-core (1.0.0)
    dm-do-adapter (1.0.0)
    dm-migrations (1.0.0)
    dm-serializer (1.0.0)
    dm-sqlite-adapter (1.0.0)
    dm-timestamps (1.0.0)
    dm-transactions (1.0.0)
    dm-types (1.0.0)
    dm-validations (1.0.0)
    dnssd (1.3.1, 0.6.0)
    do_sqlite3 (0.10.2)

    rack (1.2.1, 1.0.1)
    rack-test (0.5.3)

    Thanks,

    Carmen, do you explicitly require 'dm-migrations'? You need to do that (as opposed to dm-sqlite-adapter which gets required automatically)

    No, I didn't ... that was my problem. Thanks a lot Martin. This is awesome!
