Need Some Guides on Solr with Rails

Hi Everyone,

I am pretty new to Rails. I have very little idea about everything. But
for my new project i have been asked to do some research on Solr search
and implement it on Rails. Please provide me some link on tutorials and
guides about Solr on Rails. Trouble is… have to do it by tomorrow.

Hi!

Take a look at:

http://railscasts.com/episodes/278-search-with-sunspot

Ok… So Sunspot and solr is one and the same thing?

I tried this example…
http://techbot.me/2011/01/full-text-search-in-in-rails-with-sunspot-and-solr/

but when i run it i get the exception:

$ rake sunspot:solr:run
Requiring REXML
The syntax of the command is incorrect.
rake aborted!
You need a Java Runtime Environment to run the Solr server

Tasks: TOP => sunspot:solr:run
(See full trace by running task with --trace)

Any solution to this? I have JDK 1.7 installed with PATH variable
properly set.

Any workaround for the exception???

I guess Solr is the fulltext engine (in java) and sunspot is a rubygem
which “wraps” access to solr.

Uh, “JDK 1.7” ??? – what is the output of

java -version
echo $JAVA_HOME
echo $JRE_HOME

You have to install Solr. =)

First, make sure java is installed properly by Hassan S.'s post.
Then, download and set up Solr.
Then, install the sunspot gem

Then, RTFM. This entire post could have been avoided then…

The output of java -version is:

java version “1.7.0_01”
Java™ SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot™ Client VM (build 21.1-b02, mixed mode, sharing)

echo $JAVA_HOME is:
$ echo $JAVA_HOME
C:\Program Files\Java\jdk1.7.0_01

I dont have a JRE_HOME variable set. Is that really needed?

Right now… I am stuck with installing Solr.

Right now… I have installed Solr and am able to start it using Tomcat.

I can see the Solr Admin page (attached sreenshot). But still i get the
above error mentioned. running the command with --trace gives me this:

$ rake sunspot:solr:run --trace
Requiring REXML
** Invoke sunspot:solr:run (first_time)

If java -version works from the command line, it should work here,
because that’s what this gem is using to confirm Java is installed
(lib/solr/sunspot/java.rb) –

3 module Java
4 def self.installed?
5 java -version &> /dev/null
6 $?.success?
7 end

But you’re using Windows? What happens if you run the above
command from a shell? Does CMD understand " &> /dev/null" ?

I think Solr and me are not meant to be! :frowning:

It appears you have a MySQL, not Solr, problem.

You might want to create a new, bare Rails test app and make sure
the basics work first…

Yeah I did do a fresh creation of a project and changed from MySQL to
SQLite. And now i am back at Square 1…

By the way… I am on JDK 1.7, Win XP, Rails 3.1.3.

If you’ve got Solr working with Tomcat, then you won’t need
sunspot_solr (the packaged server) at all. All you need in that
scenario is the files generated by:

rails generate sunspot_rails:install

and a correct config file in config/sunspot.yml. In particular, you
may need to adjust the path value there to reflect your Tomcat config.

And yet you still haven’t answered my previous question…

Just to add:

java -version works from the command line.
I tried running the command from GitBash console coz on CMD it doesn’t
work:
java -version &> /dev/null

And it does not throw and error of any sort.

Which one?? If you are talking about the CMD command then i don’t think
it would work. Those are commands that work on Unix. But i am using
GitBash to run my commands. Which is like a Unix shell in Windows.

The question is what environment Rails is running in; if you’re starting
it from GitBash, does it execute system calls using that? I don’t know
and I can’t test it.

The sample code I provided is copied from the sunspot_solr check
for a Java installation, so that’s why I suggested trying it. You could
certainly try debugging directly from that gem.
