ruby - Any recommendation for a former Rails 2.3 users to migrate to Rails 5.x? -


this question has answer here:

i used program using rails 2.3.x heavily, has been while since coded. took managerial position of big company, , don't have enough time play old code. recently, realized need hone skill , start old web services , start there.

any recommendation me how started?

be aware multi-step process , can take long time. make sure test bugs after accomplishing each step since they'll appear.

  • the first step migrating rails 2.3 rails 3.0.
  • second want upgrade ruby 1.9.3.

  • pushing rails 3.0 rails 5.x covered railsguides has excellent documentation. you'll notice there number of interim steps:

    1. rails 3.0 -> rails 3.1
    2. rails 3.1 -> rails 3.2
    3. rails 3.2 -> rails 4.0
    4. rails 4.0 -> rails 4.1
    5. rails 4.1 -> rails 4.2
    6. rails 4.2 -> rails 5.0
    7. rails 5.0 -> rails 5.1

i suggest adding unit tests core features if don't have them. helps finding issues easier progress.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
