%# %# Data flow here: %# The page receives a Query from the previous page, and maybe arguments %# corresponding to actions. (If it doesn't get a Query argument, it pulls %# one out of the session hash. Also, it could be getting just a raw query from %# Build/Edit.html (Advanced).) %# %# After doing some stuff with default arguments and saved searches, the ParseQuery %# function (which is similar to, but not the same as, _parser in lib/RT/Assets.pm) %# converts the Query into a RT::Interface::Web::QueryBuilder::Tree. This mason file %# then adds stuff to or modifies the tree based on the actions that had been requested %# by clicking buttons. It then calls GetQueryAndOptionList on the tree to generate %# the SQL query (which is saved as a hidden input) and the option list for the Clauses %# box in the top right corner. %# %# Worthwhile refactoring: the tree manipulation code for the actions could use some cleaning %# up. The node-adding code is different in the "add" actions from in ParseQuery, which leads %# to things like ParseQuery correctly not quoting numbers in numerical fields, while the "add" %# action does quote it (this breaks SQLite). %# <& /Elements/Header, Title => $title &> <& /Elements/Tabs, %TabArgs &>
