Undefined method `mittens.driver' for {}:Hash

Rails

I am using radrails and this error has been killing me…

this is my controller:

def confirmCMSdb
@cmsdbProperties = session[:cmsdbProperties]
for property in params[:cmsdbProperties].keys
#puts property
#puts params[:cmsdbProperties][property]
#puts @cmsdbProperties[property]
@cmsdbProperties[property] = params[:cmsdbProperties][property]
end
session[:cmsdbProperties]
end

def getCMSdbPropsFile
return “config/hibernate.properties.txt”
end

def saveCMSdb
@cmsdbProperties = session[:cmsdbProperties]
cmsdbFile = File.open(getCMSdbPropsFile)
cmsdbFileString = String.new
for line in cmsdbFile
  tempLine = String.new
  tempLine << line[0]
   if tempLine.include?('//')== true
     cmsdbFileString += line
   end
    if tempLine.count("=") > 0 and tempLine.count("=") < 5
      tempLine = tempLine.split("=")
      #puts "TempLine: " + tempLine
      property = tempLine[0].strip
      value = tempLine[1].strip
      cmsdbFileString += property + "=" +

@cmsdbProperties[property] + “\n”
else
cmsdbFileString += line
end

end
cmsdbFile.close
cmsdbFile = File.open(getCMSdbPropsFile, "w")
cmsdbFile.puts cmsdbFileString
cmsdbFile.close

end

 def setCMSdb
cmsdbFile = File.open(getCMSdbPropsFile)
@cmsdbProperties = Hash.new
for line in cmsdbFile
  temporaryLine = String.new
  temporaryLine << line[0]
    if temporaryLine.count("=") > 0 and temporaryLine.count("=") < 5
      temporaryLine = temporaryLine.split("=")
      #puts "TempLine: " + tempLine
      property = temporaryLine[0].strip
      value = temporaryLine[1].strip
      @cmsdbProperties[property] = value
    end
  end
cmsdbFile.close
session[:cmsdbProperties] = @cmsdbProperties

end

end

and my views are:

confirmCMSdb:

<% properties = [“mittens.driver”,
“mittens.url”,
“mittens.username”,
“mittens.password”]

propertyTranslate = { “mittens.driver” => “Mittens Driver”,
“mittens.url” => “Database URL”,
“mittens.username” => “Username”,
“mittens.password” => “Password”}%>

Please confirm the following changes to the CMS database Properties

<% form_tag :action => 'saveCMSdb' do %> <% rowToggle = true%> <% for property in properties%> <% if rowToggle %> <% rowToggle = false %> <% else %> <% rowToggle = true %> <% end %> <% end %>
<%= propertyTranslate[property] %> <%= @cmsdbProperties[property]%>

<%= submit_tag ‘Submit’ %>
<%end%>


<%= link_to ‘Back’, :action => ‘list’ %>

and setCMSdb:

<% properties = [“mittens.driver”,
“mittens.url”,
“mittens.username”,
“mittens.password”]

propertyTranslate = { “mittens.driver” => “Mittens Driver”,
“mittens.url” => “Database URL”,
“mittens.username” => “Username”,
“mittens.password” => “Password”}%>

Set CMS database Properties

<% form_tag :action => 'confirmCMSdb' do %> <% rowToggle = true%> <% for property in properties%> <% if rowToggle %> <% rowToggle = false %> <% else %> <% rowToggle = true %> <% end %> <% end %>
<%= propertyTranslate[property] %> <%= text_field :cmsdbProperties, property, {"value" => @cmsdbProperties[property] }%>

<%= submit_tag ‘Submit’ %>
<%end%>


and in case u need it, this is my text file:

// The mittens driver; for PostgreSQL, use org.postgresql.Driver
(contained in postgresql.jar)

mittens.driver=org.postgresql.Driver

// The url of the database, of the form
jdbc:postgresql://servername:portnumber/databasename for PostgreSQL

mittens.url=jdbc:postgresql://traveltimes.ccit.berkeley.edu:5432/mittenstest

// The username for the database

mittens.username=mittens

// The password for the database

mittens.password=ccit!23

// The dialect to use; use org.hibernate.dialect.PostgreSQLDialect for
PostgreSQL

mittens.dialect=org.hibernate.dialect.PostgreSQLDialect

// JDBC batch size

mittens.batch_size=100

// Should we show SQL ?

mittens.show_sql=false

#dbcp.initialSize=5

#dbcp.maxActive=15

#dbcp.minIdle=2

#dbcp.maxIdle=10

c3p0.acquireIncrement=2

c3p0.initialPoolSize=5

c3p0.minPoolSize=2

c3p0.maxPoolSize=16

c3p0.maxStatements=0

c3p0.numHelperThreads=4

and the error i am getting is the following:
Showing app/views/initial_parameters/setCMSdb.rhtml where line #28
raised:
undefined method `mittens.driver’ for {}:Hash

Plz guys any help is highly appreciated!!!

I replaced this:
<%= text_field_tag “cmsdbProperties[mittens.driver]”,
@cmsdbProperties[property] %>
by this:
<%= text_field_tag “cmsdbProperties[property]”,
@cmsdbProperties[property] %>

and the setCMSdb html file now works but the confirmCMSdb is still not
working because it is not taking the properties we previously inputed in
order to confirm them and save them.

Any thoughts on that???
