私は最近、herokuに自分のアプリを配備する必要があるので、私は最近postgresqlに移行しました。postgresqlへの移行 - アクションの作成がもう機能しない
しかし、私はいくつかの問題に遭遇しています。
はもう動作しない機種シフトのためのアクションを作成します。マイ：
エラーメッセージは次のとおりです。
2 error(s) on assignment of multiparameter attributes
モデル：
class Shift < ActiveRecord::Base
attr_accessible :starts_at, :ends_at, :happens_on, :employee_id
belongs_to :employee
has_one :company, :through => :employee
validates :employee_id, :presence => true
validates :happens_on, :presence => true
validates :starts_at, :presence => true
validates :ends_at, :presence => true
end
コントローラのアクション "作成"：
def create
@title = "New Shift"
@shift = Shift.new(params[:shift])
if @shift.save
redirect_to shifts_path, :flash => { :success => 'Shift created!' }
else
render action: "new"
end
end
{"utf8"=>"✓",
"authenticity_token"=>"dH017fvWEGUWj3VPi7TssjL3BpjxzcC4Idjjc=",
"shift"=>{"employee_id"=>"3",

"starts_at(5i)"=>"06:00:00",
"ends_at(5i)"=>"09:30:00"},
"commit"=>"Create Shift"}
そして、私のフォーム：：
<%= simple_form_for @shift, :wrapper => :inline do |f| %>
<% if f.error_notification %>
<div class="alert-message error fade in" data-alert="alert">
<a class="close" href="#">×</a>
<p><%= f.error_notification %></p>
</div>
<% end %>
<%= f.association :employee, :input_html => { :class => "span4" }%>
<%= f.input :happens_on, :input_html => { :class => "span4" }, :as => :date_picker %>
<div class="clearfix">
<label for="shift_starts_at_5i">Start Time</label>
<div class="input"><%= time_select "shift", "starts_at", { :default => Time.now.change(:hour => 21), :simple_time_select => true, :minute_interval => 30, :time_separator => "", :start_hour => 6, :end_hour => 20 } %>
</div></div>
<div class="clearfix">
<label for="shift_ends_at_5i">End Time</label>
<div class="input"><%= time_select "shift", "ends_at", { :default => Time.now.change(:hour => 21), :simple_time_select => true, :minute_interval => 30, :time_separator => "", :start_hour => 6, :end_hour => 20 } %>
</div></div>
<div class="actions">
<%= f.button :submit, :class => 'primary' %>
<%= button_tag 'Cancel', :type => :reset, :class => "btn" %>
</div>
<% end %>
