Rails-将嵌套参数保存为表格

Question

My params for a nested form look like this:

"answer_group"=>{"539"=>{"answer_text"=>{"Scoreboard Report"=>"0", "GBG Observation"=>"1", "Data Review"=>"1", "Coach Probe"=>"0", "Team Assignment"=>"0", "Probe"=>"0", "Joint Probe"=>"0", "Weekly Scoreboard"=>"0"}}, "556"=>{"1034"=>{"column1"=>"n/o", "column2"=>"1", "column3"=>"is", "column4"=>"this", "column5"=>"working"}, "1035"=>{"column1"=>"n/o", "column2"=>"1", "column3"=>"", "column4"=>"", "column5"=>""}}

How do I save and access the nested params if keys are question.id ? I have attributes for column1 ... column5 in the table, everything else should save to answer_text .

Something like answer_attributes["#{question.id}"] ?

Answer 1

For saving, take a closer look at accepts_nested_attributes_for . The Rails framework provides a mechanism for doing what you've described.

For accessing, what you have would work but the interpolated string is the same thing as answer_attributes[question.id.to_s] , which is arguably more readable.

Hope this helps.
