Ruby on rails Rails 4-协会

我正在尝试在Rails 4中制作一个应用程序

我有个人资料模型和组织模型

Profile.rb：属于：组织 organization.rb有很多：简介

My profile表有一个名为：Organization_id的属性

在我的个人资料显示页面中，我想显示个人资料所属组织的名称

我有：

                <%= @profile.organisation.try(:title) %>

我在配置文件控制器中的强参数，但没有任何区别

当我填写个人资料编辑表时，我可以选择一个组织。我勾选了这个框，希望在profiles show页面中看到它的标题。它是空白的

当我进入控制台并尝试：

o = Organisation.where(profile_id:9)

它给出了以下错误：

  Organisation Load (6.1ms)  SELECT "organisations".* FROM "organisations" WHERE "organisations"."profile_id" = 9
PG::UndefinedColumn: ERROR:  column organisations.profile_id does not exist
LINE 1: ...LECT "organisations".* FROM "organisations" WHERE "organisat...
                                                             ^
: SELECT "organisations".* FROM "organisations" WHERE "organisations"."profile_id" = 9
ActiveRecord::StatementInvalid: PG::UndefinedColumn: ERROR:  column organisations.profile_id does not exist

ActiveRecord::RecordNotFound in ProfilesController#show
Couldn't find Organisation with 'id'=

Extracted source (around line #17): - it points to this line:
    @organisation = Organisation.find(params[:organisation_id])

有人能看出我做错了什么吗

Vishal的建议：

彼得的建议：

Peter的建议修改为（使profile_id为单数而非复数）：

Vishal的下一个建议：

下面是彼得的答案

我使我的配置文件控制器显示操作：

  def show
    @profile = Profile.includes(:industries).find(params[:id])
    @organisation = Organisation.find(params[:organisation_id])
    @profiles = @organisation.profiles
  end

当我保存并重试时，出现以下错误：

  Organisation Load (6.1ms)  SELECT "organisations".* FROM "organisations" WHERE "organisations"."profile_id" = 9
PG::UndefinedColumn: ERROR:  column organisations.profile_id does not exist
LINE 1: ...LECT "organisations".* FROM "organisations" WHERE "organisat...
                                                             ^
: SELECT "organisations".* FROM "organisations" WHERE "organisations"."profile_id" = 9
ActiveRecord::StatementInvalid: PG::UndefinedColumn: ERROR:  column organisations.profile_id does not exist

事实上，问题的出现是因为表单输入字段要求一个复选框。这是一个问题，因为它需要一系列输入（当每个配置文件只能有一个组织时）。当我删除复选框要求时，表单输入元素变成一个选择列表。然后，submit可以保存组织，标题显示正确。

嘿，在您的组织表中没有名称为

profile\u id

的列，并且您在

where

子句中对该列添加了条件，因此为您提供了此issueHi Vishal，但为什么我需要在组织中添加profile\u id，当档案属于组织时？是，不需要将档案id放在那里，但您可以选择这种方式。另一方面，您可以编写查询，如

organization.includes（：profiles）。其中（：profiles=>{:id=>9}）

profile有组织id，组织根据您的关联有组织id。表单中的值应该是organization_id而不是id。在您的示例查询中，它应该是：organization.where（profile_id:[9]），但您实际需要：profile.where（organization_id:params[：organization_id]）@VishalJAIN no，OP不需要

profile_id

列在

Organizations

表中，只有

profiles上的
organization\u id
