how to do more than one updates in one controller in ruby on rails
I have two models as x and y, such that:
y.rb:
class y < ActiveRecord::Base
belongs_to :x
end
x.rb:
class X < ActiveRecord::Base
has_many :Ys
end
my controller will be:
x.controller.rb:def update
@x = X.find(params[:id])
@x.update_attributes(params[:x])
@y = (params[:y])
@y.each { |t| t.attributes = params[:y][t.id.to_s] }
@x.ys.build(attributes)
flash[:notice] = 'X was successfully updated.'
redirect_to :action => 'edit'
end
开发者_如何学运维It's not updating the y data and giving error as:
undefined method `attributes=' for ["s", "1233"]:Array
params[:y]
looks to be an array of arrays; that is, for each instance of Y described in params, there's a separate array. Therefore when you do @y.each
, you're iterating over a bunch of arrays, not a bunch of Ys.
It seems that t is an array not an ActiveRecord object.
From your pseudo-code bug is here
@y = (params[:y])
