Overview

Theme: search and queries

Date: 2007-12-03

 

Wagn 0.9 is a big one: the first release with all the core features of a true wiki database.  New features include a query language, search cards that perform those queries, pointer cards, a cleaner interface for new users, and significant improvements to the templating and transclusion systems.  The initial migration path has also been streamlined to ease installations.

 

Point releases:

 

New Features

  • Enhanced Search
    • Fulltext search: word variations/ relevance ranking
      (currently only in Postgres -- requires additional installation / configuration)
    • "Go to card" bar -- autocompletes with card name; goes directly to card
  • WQL -- Wagn Query Language
    •  World's first wiki query language?
      • can query cards based on type, name, connections, links, inclusions, etc.
      • JSON syntax
    • Can use "Search cards" to store and run queries
      • links to result cards in closed search card
      • includes result cards (closed) in open search card
    • Auto-generated Cards provide simple queries about all existing cards.
  • Card Views
    • clean printing css
    • new page layouts
      • noside: normal, sans sidebar
      • blank: no sidebar / no-header
      • none: no sidebar / no header / no background
    • content view allows access to bare content
  • Interface
    • related card section moved to tab  
    • new pointer cardtype with autocomplete
    • total result counts on all query results (eg 1 to 25 of 300) 
    • autocomplete on creating connection cards

Upgrade Notes

  1. You will need to install json gem! 
    sudo gem install json
  2. for testing, you need flexmock gem
  3. memory_cache is giving us some grief, so add this to config/wagn.rb
    ActionController::Base.fragment_cache_store = :file_store
    (mem_cache also works, if you've got it installed)
  4. fulltext search is now supported in postgres (see below)


Installing postgres fulltext search


requires: postgres 8.2.x
  1. install tsearch2
    cd $PSQL_SRC_DIR/contrib/tsearch2/
    make
    sudo make install

    sudo -u postgres make installcheck

  2. configure wagn.rb
    System.enable_postgres_fulltext = true
    System.postgres_src_dir = "$PSQL_SRC_DIR"
  3. rake wagn:prepare_fulltext
    this step makes a number of assumptions- that you have sudo permissions,
    there is a user postgres with priveleges to add c-functions to the db. etc.
    if these cause trouble, edit lib/tasks/prepare_fulltext.rake
