在rails关联的ruby中未定义的方法`where'

Question

我有两个表table1和table2与has_many belongs_to关系（table1有很多table2，table2属于table1）我写的值就像table2.table1.where(.....)但我有以下错误

NoMethodError: undefined method `where' for #<table1:0xc59764c> 

Answer 1

If table2 belongs to table1 , then calling table2.table1 will give you a single object of type table1 . You can't call where on a single object (nor does it make sense to do so), only on a table or relation.
