Hi all,
I would like to develop an application that combines JRuby, Rails and
Neo4j. When trying to use the latest version of Rails (5.0.0.beta1), I get
a complaint regarding a missing activesupport gem. Well, after switching to
Rails 4.2.6, and installing neo4j, I ran into the following problems, for
which I also hereby report the temporary solutions:
1) START NEO4j: be rake neo4j:start
====> PROB: NameError: uninitialized constant
ActiveSupport::EventedFileUpdateChecker
I disabled the "line config.file_watcher =
ActiveSupport::EventedFileUpdateChecker" in
config/environments/development.rb
THEN re-ran 1)
===> PROB: NoMethodError: undefined method `to_time_preserves_timezone='
for ActiveSupport:Module
commented out the line ActiveSupport.to_time_preserves_timezone = true in
config/initializers/new_framework_defaults.rb:15
THEN re-ran 1)
===> PROB: NoMethodError: undefined method
`halt_callback_chains_on_return_false=' for ActiveSupport:Module
commented out the line config/initializers/new_framework_defaults.rb:18
THEN re-ran 1)
===> PROB: NoMethodError: undefined method `perform_caching=' for
ActionMailer::Base:Class
Set config.action_mailer.perform_caching = true (originally false) on line
32 of config/development
// from https://github.com/rails/rails/issues/17657
BUT IT DID NOT HELP
1) I then commentd out this line in config/application.rb: require
"action_mailer/railtie"
2) commented ou the following lines in config/environments/development
config.action_mailer.raise_delivery_errors = false
config.action_mailer.perform_caching = false
OK, at this point, I managed to start neo4j with rake neo4j:start
without any more issue
2) THEN, I ran "rails s" to start the rails server, after generatin a
model, a controller, and a view. Unfortunately, I ran into the following
issue reported below:
