Bulk Update in RethinkDB -

i'm trying update multiple documents in rethinkdb, based on precalculated values in hash. i.e.

given table stats primary key slug data

[{slug: 'foo', stats: {}}, {slug:'bar', stats:{}}] 

and given hash values

updated_stats = {   'foo' => {a: 1, b: 2},    'bar' => {a: 3, b: 4} } 

i can this

updated_stats.each{|k,v|    r.table('stats').get(k).update{|s|      { :stats => v }    }   } 

so, why can't following?

r.table('stats').get_all(*updated_stats.keys).update{|s|    { :stats => updated_stats[s["slug"]] }   } 

the rql shows nil value of updated_stats[s["slug"]]. appreciate on this. thanks.

it's tricky problem.

here's solution first.

r.table('stats').get_all(*updated_stats.keys).update{|s|    { :stats => r.expr(updated_stats).get_field(s["slug"]) }  }.run() 

then updated_stats ruby hash when use brackets, it's usual bracket operator, , since updated_stats doesn't have key s["slug"], returns nil. have wrap updated_stats in r.expr().

then brackets in ruby used nth, get_field, slice etc. , when given variable, cannot guess 1 should use. have explicitly want use get_field. add bracket term, should fix problem -- see https://github.com/rethinkdb/rethinkdb/issues/1179

sorry ran this!
