使用 rails 4 和 ruby 2。
从嵌套表单中保存嵌套属性时遇到问题。我可以看到参数在提交后通过表单传递。我有 2 个表:文档和薪水报告。我检查了日志,唯一收到插入的表是salary_reports,而不是文档。可能是什么问题呢?
楷模:
class SalaryReport < ActiveRecord::Base
STATUS = %w[new waiting_for_approval approved dissaproved]
belongs_to :user
has_many :documents
accepts_nested_attributes_for :documents
end
class Document < ActiveRecord::Base
TYPES = %w[sales valuation mileage expense]
belongs_to :salary_report
end
控制器
def new
@salary_report = SalaryReport.new
@salary_report.documents.build
end
def create
@salary_report = SalaryReport.new(salary_report_params)
if @salary_report.save
redirect_to salary_reports_path, notice: "Lönerapporten sparades korrekt!"
else
render :new, notice: "Något gick fel när lönerapporten skulle sparas!"
end
end
private
def salary_report_params
params.require(:salary_report).permit(:user_id, :approved_by_admin_id, :status, :comment_from_created_by, :comment_from_admin, :total_sales_since_year_start, :date_sent, :date_of_approval, :total_buffer, :salary_period, documents_attributes: [:id, :description, :type, :total])
end
提交表单后登录:
