I'm looking for a way to user Neo4j 2.0 in a Play 2.2.1 application.
Everything I find is only working with either an older version of Neo4j or Play 2.2.1. Like this: https://github.com/sgougi/play21-frames-neo4j-plugin
the current version off the plugin 1.2.1 supports play 2.2.1 and neo4j 1.9.5 using spring data.
Currently i am lifting the neo4j version to 2.0 Beta as Johannes already mentioned.
If you have any questions how this plugin works you can ask me and Johannes.
tuxBurner is developing a play-neo4jplugin and shares his code on github at https://github.com/tuxBurner/play-neo4jplugin . This plugin is really cool and i am enjoying it a lot in a lot of projects.
Currently this version runs on play 2.1.2 and neo4j 1.9.5, but he will release the next days the lift to play 2.2 and neo4j 2.0.0-RC1.
Just wait for a few more days and enjoy :)
Cheers,
Johannes

I have an application which loads some external data based on gremlin.
I want to use it to load the data into a Neo4j database.
I saw that there was partial support for gremlin in previous versions but couldn't find any solution for latest version.
I'll be happy to hear if it is still possible and how can it be done.
At this point, TinkerPop expects to support 3.4.11 in its future 3.5.0 release (here) which is yet several months away. For TinkerPop to support 4.0 it would need a fresh release of the neo4j-tinkerpop-api-impl to be released with that version. It seems an issue has been created for that here.
I have several applications created with grails 1.2.2. I need to modify one of these applications to work with multiple datasources. It seems that my best option is to upgrade to a new version of grails. I'm worried that trying to go straight to grails 3 will cause major issues, but am not sure which versions to step through if I'm going to upgrade gradually. Any advice? I apologize for this being so open ended.
The first info about support for multiple databases in official docs exists in version 2.0.0:
http://docs.grails.org/2.0.0/guide/conf.html#multipleDatasources
Check out this guide for upgrade:
http://docs.grails.org/2.0.0/guide/gettingStarted.html#upgradingFromPreviousVersionsOfGrails
Right now we are using Neo4j 1.9.9 version(embedded mode) with tinkerpop blueprints 2.4 API. We are planning to upgrade our Neo4j to 2.3. But I see that blueprints is not compatible with neo 2.3. Since our system is stable now we are trying to upgrade our neo4j without disturbing the crud layer much.
1.Can any one help me here to understand why blueprints is not compatible with 2.3?
2. If I plan to use spring-data from my understanding it is not for embedded mode.Can some one share if you faced this scenario and how you approached the problem?
I'm rather new to grails and I'm about to start a new grails project. I'm very confused with what version to go with based on the tools not being ready to support the newest version. I've read version 3 was a complete rewrite from ground up which my gut says should be the version to go with considering the project is brand new, but I'm discovering none of the tools are ready for version 3.
I was successfully able to get version 3 up with intellij with out grails support and the same goes for ggts.
With that being said, I don't know how to run the app in ggts since grails-runapp doesn't work
with ggts, I used the following tutorial https://tedvinke.wordpress.com/2015/04/10/grails-3-released-installing-gradle-and-groovy-2-4-support-in-eclipseggts/ but I've been able to figure out how to get the app to run. Does anybody know how to do this?
My questions are
How do I run a Grails 3 app in GGTS.
Is it recommended to use Grails 3 at this point or should I use Grails 2
If you use Grails 3, what is the recommended IDE?
With Intellij I had to run it by going to the grails-app/init project run main. Is this the correct way to do it?
As of Grails 3 you don't need a special IDE To run Grails 3 application. all you need to do is to right-click on the Application class and execute to start your Grails application. To read more about IDE integration https://grails.github.io/grails-doc/latest/guide/introduction.html
Currently, not all plugins are upgraded to Grails 3. So if your project depends on some plugins that are not already upgraded this will be an issue. For example spring security is not upgraded yet, but there is a work around to use it.https://groups.google.com/forum/#!searchin/grails-dev-discuss/spring$20security/grails-dev-discuss/jOF0jw_BiCs/tOxd0NZpaxkJ
Finally, both Intellij community edition and GGTS supports Grails3. But if you want special grails features like GSP syntax highlighting use GGTS or IDEA Ultimate edition.
IntelliJ idea 15 is out. Try that. The support for Grails 3 is built in.
Choose Grails 3 instead of Grails 1/2 in project selection.
I have 6 projects running Grails 2 for over 1 year.
So far I have not encountered any need to upgrade them to Grails 3.
I use the latest edition of IntelliJ Ultimate 2016.2, and for the most part it works good with Grails 2. The debugger still throws a lot of EVAL errors, but I am able to evaluate my variables in real time.
The biggest problem I've encountered so far is plugins that are not compatible with Java 1.8. Some of the plugins still have to run in Java 1.7.
Lastly, I'd say if your project is still new, look into using NodeJs. It seems to be more popular than Grails at this point.
I think intellij is better for development in grails from my experience.
Grails 3 will be good choice for development. there are lot more features in there
https://dzone.com/articles/whats-new-grails-3
also document site will give you clear concept about it
http://docs.grails.org/latest/
Considering the fact that grails version 2 is different from grails version 3; it will be good if you start with version 3 and avoid the possibility of running into upgrade issues from 2.x to 3.x in the future
You can use Netbeans or Intelij. I use Netbeans.
Facing a lot of issues in Database migration in Grails 3.1.6. Not helping at all.
I think remaining a few days in version 2 will be beneficiary as long as version 3 stables.
Besides The GGTS support will be needed as Intellij IDEA 15 community edition does not support Grails. So better back to the old versions.
I have been working with rails 2.3.5. I am gonna start a new project on rails. Should i continue using the earlier version or should i hop on to rails > 3 ? If so which is the more stable version?
It is better to use rails 3.0.x version as these days lot of new plugins(like active_reload) are targeted only for 3.x version.
3.1.x have lot of cool features(like asset pipeline, saas integration, coffescript integration, etc), but its still a release candidate and I faced some issues while using it. I guess we have to wait for the stable 3.1.x release.
I have been using 3.0.7 for a while and found it to be very stable.
3.0.10 is recently released and you can easily upgrade to it from 3.0.7 any time you want in the future.
If you are stuck to 2.x version you will be missing cool features like mentioned here: http://net.tutsplus.com/tutorials/ruby/5-awesome-new-rails-3-features/
For a new project, I would use Rails 3.1 or for a bit more stability, 3.0.7. There are some noticeable differences compared to 2.3, but it will be supported for longer and most development of new gems and documentation are being written for Rails 3.
You should definitely NOT use 2.3 and earlier.
The Rails framework is improving at a steady pace and if there is a downside to that is that it can be a pain to upgrade from version to version, especially as regards to major version changes which introduce tons of backward incompatibilities.
Why then would you want to put yourself in the hole at the get go.
Another issue is how ready and mature is the ecosystem (ruby, popular gem packages, etc.). This leads you to consider whether you should start with 3.0.10 or 3.1 release candidate.
It turns out the great majority of gems working with Rails 3.0 is also working fine with Rails 3.1.
The little downside is that 3.1 is still in release candidate status but it's all but ready for final release and that should come within a matter of days or maximum a couple weeks (as of today Aug. 25, '11).
I would strongly recommend you start all new apps with 3.1. That's what I'm doing.
