i trying retrieve json pass flot graph. know json right because hard coded check, i'm pretty sure i'm not passing right because it's not showing up. here's javascript: var total = $.ajax({ type: "post", async: false, url: "../api/?key=xxx&api=report&crud=return_months&format=json" }).responsetext; //var total = $.evaljson(total); var plot = $.plot($("#placeholder"),total); here's json: [ { data: [[1,12], [2,43], [3,10], [4,17], ], label: "e-file"}, { data: [[1,25], [2,35], [3,3], [4,5], ], label: "bank products" }, { data: [[1,41], [2,87], [3,30], [4,29], ], label: "all returns" } ], {series: {lines: { show: true },points: { show: true }}, grid: { hoverable: true, clickable: true }, yaxis: { min: 0, max: 100 }, xaxis: { ticks: [[1,"january"],[2,"february"],[3,"march"],[4,"april"],[5,"may"],[6,"june"],[7,"july"]...

i have parent-child relationship between 2 objects. parent :has_many :children child :belongs_to :parent when creating new parent, in same controller, i'm creating child. @mom = parent.new @child = child.new @mom.children << @child that seems go okay, parent has 1 more attribute - parent has favorite child @mom.favorite_child = @child seems should work, except let's 61st child in database, gets id of 61 (and know happening, because when check database, child record has id of 61). reason, when assign @child parent's "favorite_child" attribute, "favorite_child" gets set "1" - when need set "61". clues? seems parent needs like class parent has_many :children has_one :favorite_child, :foreign_key=>'favorite_child_id', :class_name => 'child' otherwise, doesn't know it's foreign key relationship, , you're trying assign object integer.

what mean if receive warning? mean project referencing same assembly different files? this can commonly occur if "project reference" has somehow reverted file reference. if have project referencing other projects, try removing references , re-adding them. can occur if 2 dependent projects each reference different version of third assembly.

i can't make system.linq (aka linq objects) work. running monodevelop 2.2.1 in ubuntu 10 lucid lynx mono 2.4.4. they advertise in site implemented linq, can't find enumerable.range or toarray() . what's wrong? i guess need is: in project options set "runtime version" "mono/.net 3.5" add reference system.core package (right click references in solution explorer) add "using system.linq" module after code should compile , execute hope helps, regards
