Couldn't find this specific instance anywhere; I might be missing something simple, but here it goes.
Say I have an array:
["Field1", "Field2"]
I need to convert this into an array of hashes, as such (the FieldType key/value is a default value)
[{"Name"=>"Field1", "FieldType"=>"Text"},
{"Name"=>"Field2", "FieldType"=>"Text"}]
How would I go about doing this? The below clearly doesnt work:
fields.each do |field|
fieldResults << {"Name" => field, "FieldType" => "Text"}
end
Assuming fieldResults is an array, what you wrote should work, though it's more idiomatic to use a better-suited function, like map.
fields.map {|field| { 'Name' => field, 'FieldType' => 'Text' }}
If fields = ["Field1", "Field2"] and fieldResults is initialized to [] your code should work. But as Chuck said fieldResults = fields.map {|field| { 'Name' => field, 'FieldType' => 'Text' }} is more ideomatic.
By the way: The ruby naming convention for symbols, methods and variables is to use snake_case (underscores) rather than camelCase for multiple word names. Like field_results instead of fieldResults
You can take the below approach too :
fields = ["Field1", "Field2"]
result = fields.map{|i| {"Name" => i}.update({"FieldType" => "Text"})}
# => [{"Name"=>"Field1", "FieldType"=>"Text"},
# {"Name"=>"Field2", "FieldType"=>"Text"}]
Another way of doing this.
fieldResults = []
["Field1", "Field2"].each{|e| fieldResults << Hash["Name",e,"FieldType","Text"]}
1.9.3 (main):0 > fieldResults
=> [{"Name"=>"Field1", "FieldType"=>"Text"},
{"Name"=>"Field2", "FieldType"=>"Text"}]
