Public Instance Methods

adapt_response(request, response) click to toggle source

This method will evaluate the :body value if the params.params == :ruby ... otherwise, the body is returned as is. The return object has methods attached, :request and :response. These methods give you access to the original request and response from the connection.

adapt_response will raise an InvalidRubyResponse if :wt == :ruby and the body couldn't be evaluated.

# File lib/rsolr/client.rb, line 208
def adapt_response request, response
  raise "The response does not have the correct keys => :body, :headers, :status" unless
    %(body headers status) == response.keys.map{|k|k.to_s}.sort
  raise RSolr::Error::Http.new request, response unless
    [200,302].include? response[:status]
  result = request[:params][:wt] == :ruby ? evaluate_ruby_response(request, response) : response[:body]
  result.extend Context
  result.request = request
  result.response = response
  result
end
add(doc, opts = {}) click to toggle source

add creates xml "add" documents and sends the xml data to the update method

wiki.apache.org/solr/UpdateXmlMessages#add.2BAC8-update

single record: solr.update(:id=>1, :name=>'one')

update using an array

solr.update(

[{:id=>1, :name=>'one'}, {:id=>2, :name=>'two'}],
:add_attributes => {:boost=>5.0, :commitWithin=>10}

)

# File lib/rsolr/client.rb, line 75
def add doc, opts = {}
  add_attributes = opts.delete :add_attributes
  update opts.merge(:data => xml.add(doc, add_attributes))
end
base_request_uri() click to toggle source

returns the actual request uri object.

# File lib/rsolr/client.rb, line 22
def base_request_uri
  base_uri.request_uri if base_uri
end
base_uri() click to toggle source

returns the uri proxy if present, otherwise just the uri object.

# File lib/rsolr/client.rb, line 28
def base_uri
  @proxy || @uri
end
build_request(path, opts) click to toggle source

build_request accepts a path and options hash, then prepares a normalized hash to return for sending to a solr connection driver. build_request sets up the uri/query string and converts the data arg to form-urlencoded, if the data arg is a hash. returns a hash with the following keys:

:method
:params
:headers
:data
:uri
:path
:query
# File lib/rsolr/client.rb, line 171
def build_request path, opts
  raise "path must be a string or symbol, not #{path.inspect}" unless [String,Symbol].include?(path.class)
  path = path.to_s
  opts[:proxy] = proxy unless proxy.nil?
  opts[:method] ||= :get
  raise "The :data option can only be used if :method => :post" if opts[:method] != :post and opts[:data]
  opts[:params] = opts[:params].nil? ? {:wt => :ruby} : {:wt => :ruby}.merge(opts[:params])
  query = RSolr::Uri.params_to_solr(opts[:params]) unless opts[:params].empty?
  opts[:query] = query
  if opts[:data].is_a? Hash
    opts[:data] = RSolr::Uri.params_to_solr opts[:data]
    opts[:headers] ||= {}
    opts[:headers]['Content-Type'] ||= 'application/x-www-form-urlencoded'
  end
  opts[:path] = path
  opts[:uri] = base_uri.merge(path.to_s + (query ? "?#{query}" : "")) if base_uri
  opts
end
commit(opts = {}) click to toggle source

send "commit" xml with opts

wiki.apache.org/solr/UpdateXmlMessages#A.22commit.22_and_.22optimize.22

# File lib/rsolr/client.rb, line 84
def commit opts = {}
  commit_attrs = opts.delete :commit_attributes
  update opts.merge(:data => xml.commit( commit_attrs ))
end
delete_by_id(id, opts = {}) click to toggle source

Delete one or many documents by id

solr.delete_by_id 10
solr.delete_by_id([12, 41, 199])
# File lib/rsolr/client.rb, line 110
def delete_by_id id, opts = {}
  update opts.merge(:data => xml.delete_by_id(id))
end
delete_by_query(query, opts = {}) click to toggle source

delete one or many documents by query.

wiki.apache.org/solr/UpdateXmlMessages#A.22delete.22_by_ID_and_by_Query

solr.delete_by_query 'available:0'
solr.delete_by_query ['quantity:0', 'manu:"FQ"']
# File lib/rsolr/client.rb, line 120
def delete_by_query query, opts = {}
  update opts.merge(:data => xml.delete_by_query(query))
end
execute(request_context) click to toggle source
# File lib/rsolr/client.rb, line 152
def execute request_context
  raw_response = connection.execute self, request_context
  adapt_response(request_context, raw_response) unless raw_response.nil?
end
optimize(opts = {}) click to toggle source

send "optimize" xml with opts.

wiki.apache.org/solr/UpdateXmlMessages#A.22commit.22_and_.22optimize.22

# File lib/rsolr/client.rb, line 93
def optimize opts = {}
  optimize_attributes = opts.delete :optimize_attributes
  update opts.merge(:data => xml.optimize(optimize_attributes))
end
rollback(opts = {}) click to toggle source

send </rollback>

wiki.apache.org/solr/UpdateXmlMessages#A.22rollback.22

NOTE: solr 1.4 only

# File lib/rsolr/client.rb, line 103
def rollback opts = {}
  update opts.merge(:data => xml.rollback)
end
send_and_receive(path, opts) click to toggle source

send_and_receive is the main request method responsible for sending requests to the connection object.

"path" : A string value that usually represents a solr request handler "opts" : A hash, which can contain the following keys:

:method : required - the http method (:get, :post or :head)
:params : optional - the query string params in hash form
:data : optional - post data -- if a hash is given, it's sent as "application/x-www-form-urlencoded"
:headers : optional - hash of request headers

All other options are passed right along to the connection's send_and_receive method (:get, :post, or :head)

send_and_receive returns either a string or hash on a successful ruby request. When the :params => :ruby, the response will be a hash, else a string.

creates a request context hash, sends it to the connection's execute method which returns a simple hash, then passes the request/response into adapt_response.

# File lib/rsolr/client.rb, line 146
def send_and_receive path, opts
  request_context = build_request path, opts
  execute request_context
end
update(opts = {}) click to toggle source

POST XML messages to /update with optional params.

wiki.apache.org/solr/UpdateXmlMessages#add.2BAC8-update

If not set, opts will be set to a hash with the key 'Content-Type' set to 'text/xml'

opts can/should contain:

:data - posted data
:headers - http headers
:params - solr query parameter hash
# File lib/rsolr/client.rb, line 54
def update opts = {}
  opts[:headers] ||= {}
  opts[:headers]['Content-Type'] ||= 'text/xml'
  post 'update', opts
end

end

Protected Instance Methods

evaluate_ruby_response(request, response) click to toggle source

evaluates the response, attempts to bring the ruby string to life. If a SyntaxError is raised, then this method intercepts and raises a RSolr::Error::InvalidRubyResponse instead, giving full access to the request/response objects.

# File lib/rsolr/client.rb, line 234
def evaluate_ruby_response request, response
  begin
    Kernel.eval response[:body].to_s
  rescue SyntaxError
    raise RSolr::Error::InvalidRubyResponse.new request, response
  end
end
method_missing(name, *args) click to toggle source

converts the method name for the solr request handler path.

# File lib/rsolr/client.rb, line 223
def method_missing name, *args
  send_and_receive name, *args
end
