Question

我正在处理视图并尝试创建一个表单，其中只能选择多个单选按钮中的一个作为true。单选按钮分别与各个布尔值相连。

class ModelNameReason < ActiveRecord::Base
  MODEL_NAME_REASON_OPTIONS = {bool_one: 'Reason 1',
                                            bool_two: 'Test Reason',
                                            bool_three: 'Consumer Reason',
                                            bool_for: 'Time Contraint Reason',
                                            bool_five: 'Problem with Requirements',
                                            }

简单的HTML：

;WITH CTE AS(
         SELECT
             Player1 AS LoggedInPlayer,
             ROW_NUMBER() OVER (PARTITION BY Player1 ORDER BY datecolumn Asc) As LoggedValue
         FROM 
             yourtable
  ) 

  SELECT 
        * 
  FROM 
      CTE 
  WHERE  
      LoggedValue = 1

对要“链接”到同一变量的所有单选按钮使用相同的<form method="post"> <fieldset> <legend>What is Your Favorite Pet?</legend> <input type="radio" name="animal" value="Cat" />Cats<br /> <input type="radio" name="animal" value="Dog" />Dogs<br /> <input type="radio" name="animal" value="Bird" />Birds<br /> <input type="submit" value="Submit now" /> </fieldset> </form>属性。

仅允许选择具有不同名称的多个单选按钮。 Simple_form Rails
