所以我有两个从另一个继承的模型如下:
class OneTime < Step
has_one :due_date
accepts_nested_attributes_for :due_date
end
class Repeatable < Step
has_many :due_dates
accepts_nested_attributes_for :due_dates
end
class Step < ActiveRecord::Base
belongs_to :goal
end
我还有另一个嵌套在子类中的模型:
class DueDate < ActiveRecord::Base
belongs_to :step
end
然后我使用formtastic有这样的表格:
= semantic_form_for [@goal, @step], :url => goal_step_path(@goal, @step), :html => { :class => "ajax"} do |f|
= f.inputs :id => "step_#{@step.id}_description", :class => "description" do
= f.input :description, :input_html => { :autofocus => "autofocus"}
= f.semantic_fields_for :due_date do |due_date|
= due_date.inputs :date_due, :as => :string, :input_html => { :class => "datepicker"}, :label => "Due Date"
= f.buttons do
= f.commit_button
问题是,当我尝试加载该表单时,我收到以下错误:
Showing /Users/dc/launchtools/app/views/steps/_form.html.haml where line #4 raised:
SQLite3::SQLException: no such column: due_dates.one_time_id: SELECT "due_dates".* FROM "due_dates" WHERE ("due_dates".one_time_id = 121) LIMIT 1
Extracted source (around line #4):
我已经尝试了很多不同的东西来解决它并且没有任何效果。我也搜索了stackoverflow和谷歌,但没有发现任何有助于解决这个问题。也许我没有正确地解决问题,但我需要一些方向。有什么想法吗?
答案 0 :(得分:0)
您尝试将多个参数传递给它认为是多个字段的due_date.inputs
,您想要使用due_date.input
(单数),如下所示:
= due_date.input :date_due, :as => :string, :input_html => { :class => "datepicker"}, :label => "Due Date"
