所以我使用User
生成了devise
模型,我使用Wicked
gem为我提供了多种形式的选项,可以从用户那里获取更多数据并将其存储在用户模型中
一切都运转正常,但我知道我试图在用户拥有多个学位的地方添加另一个模型。我正在使用cocoon gem来允许我添加额外的degrees
。我可以进入多形式页面并输入学位信息,甚至可以向用户添加更多学位,但是当我提交表单时,我收到错误;
param is missing or the value is empty: user
其他所有内容实际上都会被保存,我可以查看用户和输入的其他字段但不包含度数。
用户模型:
has_many :degrees
accepts_nested_attributes_for :degrees, reject_if: :all_blank, allow_destroy: true
学位模型:
belongs_to :user
user_steps_controller(这是邪恶的宝石控制器):
class UserStepsController < ApplicationController
include Wicked::Wizard
steps :personal, :avatar_and_about_yourself, :social, :education
def show
@user = current_user
render_wizard
end
def update
@user = current_user
@user.update_attributes(user_params)
render_wizard @user
end
private
def user_params
params.require(:user).permit(:name, :middlename, :lastname, :avatar, :aboutMe, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreeName, :university, :level, :done, :_destroy])
end
end
注册控制器(用于设计):
class Users::RegistrationsController < Devise::RegistrationsController
# before_filter :configure_sign_up_params, only: [:create]
# before_filter :configure_account_update_params, only: [:update]
# GET /resource/sign_up
def new
super
end
# POST /resource
def create
super
end
# PUT /resource
def update
super
end
protected
# The path used after sign up.
def after_sign_up_path_for(resource)
user_steps_path
end
# The path used after sign up for inactive accounts.
def after_inactive_sign_up_path_for(resource)
user_steps_path
end
def sign_up_params
params.require(:user).permit(:email, :password, :password_confirmation, :name, :middlename, :lastname, :avatar, :aboutMe, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreeName, :university, :level, :done, :_destroy])
end
end
我在user_steps_controller中收到错误:
ActionController::ParameterMissing in UserStepsController#update
param is missing or the value is empty: user
并且错误在此行内:
def user_params
params.require(:user).permit(:name, :middlename, :lastname, :avatar, :aboutMe, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreeName, :university, :level, :done, :_destroy])
end
另外,我将如何查看输入的字段,例如,如果我想查看用户名:
<%= @user.name %>
但我如何展示每个学位?它只是一个循环吗?
<% @users.degree.each do |degree| %>

这个评论太长了,我完全希望能够更新它。
您遇到的问题是您的表单提交不包含任何user
参数:
Parameters: {"utf8"=>"✓", "authenticity_token"=>"EXN7ts6xPVK8vkC7q6UcNleJJWLUtKmOw41T0qsDqXCrPJ0vIHrB/6xIfpp/o+cXKR47F+6LxUY5LjXlCobKZQ==", "commit"=>"Update User", "id"=>"education"}
这可能是Wicked
,但是从RegistrationsController
的虚假使用来判断,我想它可能与格式化等有关:
-
如果您要更新current_user
,则应该不调用您的registrations
控制器。那是注册 - 你应该使用你的users
控制器:
#config/routes.rb
resource :user_steps, path: "user", only: [:show, :update] #-> url.com/user (singular resource)
#app/controllers/user_steps_controller.rb
class UserStepsController < ApplicationController
def show
end
def update
@user = current_user.update user_params
render_wizard @user
end
private
def user_params
params.require(:user).permit(:name, :middlename, :lastname, :avatar, :aboutMe, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreeName, :university, :level, :done, :_destroy])
end
end
这只是控制器;你需要看看form
是如何呈现的&amp;通过。
如果您使用上述代码发送数据,则需要提取form
HTML并显示Wicked
如何使用它。
您需要在app/views/users/show.html.erb
中查找要显示的表单,不是 /app/views/registrations
