the basic code below makes kirby complain that im trying to update a
link_to many field in my table when as can be seen I am not. Here is
some code for you to copy into irb to reproduce the error (though the
problem lies with only the pt table i have also included the code to
create the table its linked to called tt). I have read the manual many
times to no avail. I also looked through kirbys code but im a beginner
and i got lost in it 
require ‘kirbybase’
db = KirbyBase.new
db.drop_table(:pt) if db.table_exists?(:pt)
db.drop_table(:tt) if db.table_exists?(:tt)
tt = db.create_table(:tt, :task_title, {:DataType=>:String,
:Default=>‘No Title’}, :completed, {:DataType=>:Boolean,
:Default=>true}, :project, {:DataType=>:String,
:Default=>‘None’},:p_project_id, :Integer)
pt = db.create_table(:pt, :project_title, {:DataType=>:String,
:Default=>‘No Project Name’}, :p_project_id, {:DataType=>:Integer,
:Default=>0}, :p_tasks,{:DataType=>:ResultSet,
:Link_many=>[:p_project_id, :task_table, :p_project_id]})
pt.insert(:project_title => “old”) #creates record with recno = 1
pt.update(:project_title => “new”) {|r| r.recno == 1}
here is my error - p_tasks is the linked item in the other table tt.
ArgumentError: You cannot input a value for this field: p_tasks

in case your wondering, tt is a tasks table and pt is a projects table.
This is for a simple todo list app. Projects are comprised of tasks
hence the link.
Can anyone help?
