Check to see if we can connect to the db before accessing it. Fixes #396.

Fix heroku precompile assets breaking with Rails 4. Fixes #396.

This fails specs for unrelated reasons that have been addressed in #404. I have been able to deploy to Heroku with an app running Rails 4 using this fork. It should be good to merge.

This helped, thanks!

Can you rebase against master and force push?

[shekibobo]

#422 might be a better implementation of a fix for #396.

[bf4]

Yours is more consistent with current behavior.. would need to think about #422 a bit

This broke a rails4 app I'm working on. The methods don't get added. This doesn't seem like the correct way to do this.

@aaronchi Would you mind creating an issue and giving an example?

@bf4 After this patch, I get ActionView::Template::Error: undefined methodcaching_tag_list_on?' for #Class:0x007f1c477b4570` when trying to render tag_list to a form. If I remove the base.connected? part, it works.

It seems that if these methods can't be written on initialization, it breaks the functionality of the gem. Seems like #422 might be a better alternative.

Thanks.. Would you mind creating an issue with the gem version, rails version, ruby version, full error message, and a stack trace?
