我的计划模型有:
has_many :registry_patient_counts
scope :salary_and_bonus,
:joins => :registry_patient_counts,
:order => "patient_count_percentage DESC"
当我使用我的控制器开始简单的步骤时,这很有效:
programs =
Program.includes([:registry_patient_counts])
.salary_and_bonus.where('organization_id = 1')
.limit(2)
但是我的终极控制器看起来应该是这样的(如果没有范围,它看起来如何)
@programs = Program.includes(
[:registry_patient_counts, measures: :measures_off_targets])
.where('organization_id = 1')
.limit(2)
所以请注意它中有measures: :measures_off_targets
个额外内容。
所以在measure和measures_off_targets之间我也想要定义一个与前一个类似的范围....但是我不明白如何在控制器中键入这两个范围?
编辑:所以这是我们到目前为止所遵循的答案:
在Program.rb中:
scope :rpc, includes(:registry_patient_counts).order => "patient_count_percentage DESC"
scope :msr, includes(measures: :measures_off_targets)
控制器查询如下所示:
@programs2 = Program.rpc.msr.where('organization_id: 1').limit(2)
RubyMine在IDE中显示的错误是“找不到msr” 如果我忽略它并转到浏览器,仍然在Rail控制台中我收到“错误500,错误请求”并且没有任何回复。
答案 0 :(得分:0)
您可以链接范围和包含。
scope :rpc, includes(:registry_patient_counts)
scope :msr, includes(measures: :measures_off_targets)
@programs = Program.rpc.msr.where(organization_id: 1).limit(2)
# Equivalent to
@programs = Program.includes(
[:registry_patient_counts, measures: :measures_off_targets])
.where(organization_id: 1)
.limit(2)
