[Ruby] Call a function to each member

2009-09-08T16:14:23-07:00

Is there a shorter version, or do I always have to code the block syntax? Something like @documents.collect_call(:to_hash)? Btw. It's Rails so maybe there might be something in ActiveSupport.

@public_documents = @documents.map { |document| document.to_hash }

[Ruby] Named Scopes in Relations

2009-06-24T15:38:44-07:00

I have two models: Teams and Statements. A statement belongs to a team. When I try to apply a scope to the relation - I can do this with anonymous scopes. Is there a possibility to define a named scope for a relation? When I define it in my Statement Model, it will say method_is missing. Any hints?

@team.statements.scoped({ 
               :select => "statements.*, users.first_name",
               :joins => "INNER JOIN users ON users.id = statements.user_id",
               :order => 'RAND()',
               :limit => '100'}).to_json

[Ruby] Decoding a json object while converting keys to symbols

2009-06-10T18:01:09-07:00

I'm decoding a json object. The first line would be sufficient - but then I can only access the items with item["foo"]. I appreciate item[:foo]. Is there a more elegant way to do that?

def schema
  raw_schema_json = ActiveSupport::JSON.decode(self.schema_json)
  schema = []
  raw_schema_json.each do |raw_item|
    item = {}
    raw_item.each do |key, value|
      item[key.to_sym] = value
    end
    schema.push(item)
  end
  schema
end
