[noob] Blaze crashes after creating a new query #14

Closed sbelak closed 9 years ago

sbelak commented 9 years ago

The following is probably due to me not knowing Rails and not doing something obvious, but if I create a new blank Rails project with only Blaze as per readme, Blaze ostensibly works, but after I save any query, going to the index page crashes with:

NameError in Blazer::Queries#index
Showing /Library/Ruby/Gems/2.0.0/gems/blazer-0.0.5/app/views/blazer/queries/index.html.erb where line #17 raised:

uninitialized constant Blazer::Query::User

This is on a completely vanilla install and happens regardless of being run in production or development or what I set for the db connection (which works fine).

Environment:

@sbelak thanks for reporting! I've updated Blazer to work without a user model if you set Blazer.user_class = nil in an initializer. Will attempt to do this automatically.

aradriel commented 9 years ago

If i (as a non ruby person) follow the docs, i ran into the same error. how can i add a mastermind/user to blaze?

sbelak commented 9 years ago

I solved by using the latest version from master (incorporating ankane's patch above) and adding Blazer.user_class = nil to config/environments/production.rb (and development.rb)
