我第一次尝试使用干燥验证宝石。
我想为多模型(用户,地址,公司)创建表单
我决定使用干燥验证器,但无法验证表单。我收到验证程序错误“:user => [“必须为哈希”]“
如何使其工作?
app / controller / users_controller.rb
class UsersController < ApplicationController
def new
@user = User.new
@user.address = Address.new
@user.company = Company.new
@user.company.address = Address.new
end
def create
@user = User.new
validation = UserValidator::UserSchema.call(params)
if validation.success?
@user.attributes = validation.output[:user]
@user.save
redirect_to new_user_path, notice: 'Form send!'
else
redirect_to new_user_path, warning: "#{validation.errors}"
end
end
end
app / models / user.rb
class User < ApplicationRecord
has_one :company
has_one :address, as: :addressable
accepts_nested_attributes_for :company, :address
end
app / validators / user_validator
class UserValidator
UserSchema = Dry::Validation.Params do
required(:user).schema do
required('first_name').filled
end
end
end
在创建操作中打印参数输出:
<ActionController::Parameters {"utf8"=>"✓","authenticity_token"=>"Dszr0k90aklK1NC4uGcemAl+yFa9ppMDo/gCLJt2wC1WjTgLC+NFebRqm6iqtVTnQzRgd7v0icntxETbxJ7v9g==", "user"=>{"first_name"=>"Test", "last_name"=>"asdasdasdasd", "email_address"=>"sadasdasd", "date_of_birth"=>"sdasda", "phone_number"=>"", "address_attributes"=>{"street"=>"dadadadsdad", "city"=>"asdasdad", "zip_code"=>"dasd", "country"=>"adsa"}, "company_attributes"=>{"name"=>"", "address_attributes"=>{"street"=>"", "city"=>"", "zip_code"=>"", "country"=>""}}}, "commit"=>"Submit", "controller"=>"users", "action"=>"create"} permitted: false>
答案 0 :(得分:0)
dry-validation(和dry-schema)不接受ActionController::Parameters
,您应该将其转换为哈希。
尝试params.to_unsafe_hash
或params.permit(...).to_h
