i have insert data 2 tables, items , class_items.

i have worked svn, , apache not together. my customer has live site @ 1 address, , svn repository on machine @ address. i have checked out whole 9 yards directory on local (windows xp) machine running apache/2.0.59. (there no problems configuring local sites.) i 3 directories in checkout: branches, tags, trunk which 1 should use documentroot ? thanks reading. you're checking out wrong directory. check out either trunk , or subdirectory of branches or tags . otherwise end checking out dozens of copies of code, in different versions. as document root, depends on how project organized. same directory checked out, or subdirectory. latter more likely, since project contain code shouldn't accessible web.

i'm writing rails 3 generator creates 2 different models. here's simplified example of i'm trying do: def my_generator_task invoke "model", ["foo"] invoke "model", ["bar"] end the problem thor invoke method invokes task once, second call "model" task never happens , "bar" model never created. know elegant way accomplish this, preferably in way doesn't break ability run "rails destroy" generator? one more thought, way possible run multiple model generator without migration rails::generators.invoke("active_record:model", ["foo", "--no-migration" ]) rails::generators.invoke("active_record:model", ["bar", "--no-migration" ])

i have coded various graph search (a*, dfs, bfs, etc..) algorithms many times over. every time, real difference actual search states searching over, , how new states generated existing ones. i faced yet search-heavy project, , avoid having code , debug general search algorithm again. nice if define search state class, including information generating successive states, heuristic cost, etc, , plug in kind of existing search framework can of heavy lifting me. know algorithms aren't particularly difficult code, there enough tricks involved make annoying. does exist? couldn't find anything. perhaps quickgraph of interest. quickgraph provides generic directed/undirected graph datastructures , algorithms .net 2.0 , up. quickgraph comes algorithms such depth first seach, breath first search, a* search, shortest path, k-shortest path, maximum flow, minimum spanning tree, least common ancestors, etc
