邪恶宝石与茧宝石和设计用户模型 [英] Wicked Gem with cocoon gem and devise user model

问题描述

所以我有一个用户模型生成与 devise ，我使用邪恶 gem给我多种选择，从用户那里获取更多数据并将其存储在用户模型中。

So I have a User model generated with devise, and I am using Wicked gem to give me multiform option on taking more data from the user and storing it in the user model.

一切都正常，但知道我'尝试添加另一个模式，用户拥有多个学位。我正在使用茧宝石来允许我添加额外的度。我可以去多页面，输入学位信息，甚至添加更多的学位，但是当我提交表单我收到一个错误;

Everything is working fine but know I'm trying to add another model where user has many degree. I am using cocoon gem to allow me to add extra degrees. I am able to go to the multiform page and enter degree information and even add many more degrees to the user, but when i submit the form i get an error;

param is missing or the value is empty: user

获得保存，我可以查看用户和输入的其余字段，但不是度数。

Everything else actually gets saved am i can view the user and the rest of the fields entered but non of the degrees.

用户模型：

has_many :degrees
accepts_nested_attributes_for :degrees, reject_if: :all_blank, allow_destroy: true

度数模型：

belongs_to :user

user_steps_controller（这是恶魔宝石控制器）：

user_steps_controller (this is the wicked gem controller):

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（for devise）：

Registration controller (for devise):

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：

Im getting an error in the user_steps_controller:

ActionController::ParameterMissing in UserStepsController#update
param is missing or the value is empty: user

，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，我该怎么去查看输入的字段例如，如果我想查看用户名：

Also how would i go and view the entered fields, for example if i wanted to view user name it is:

<%= @user.name %>

但我如何显示每个学位？它只是一个循环吗？

but how would i show each degree? is it just a loop?

<% @users.degree.each do |degree| %>

推荐答案

这太久没有评论，我完全期望更新

This is too long to comment, I fully expect to update it.

您的问题是您的表单提交不 包含任何 user params：

The problem you have is that your form submission does not include any user params:

Parameters: {"utf8"=>"✓", "authenticity_token"=>"EXN7ts6xPVK8vkC7q6UcNleJJWLUtKmOw41T0qsDqXCrPJ0vIHrB/6xIfpp/o+cXKR47F+6LxUY5LjXlCobKZQ==", "commit"=>"Update User", "id"=>"education"}

这可能是 Wicked ，但判断您的虚假使用注册控制器，我想象可能是t o使用格式化等：

This might be Wicked, but judging form your spurious use of RegistrationsController, I'd imagine it could be to do with formatting etc:

-

如果您要更新您的 current_user ，您应该不调用注册控制器。这是针对注册 - 您应该使用用户控制器：

If you're updating your current_user, you should not be invoking your registrations controller. That is for registrations -- you should be using your users controller:

#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;您需要查看表单正在呈现的方式通过。

This is just the controller; you need to look at how the form is being rendered & passed.

如果您使用上述代码发送数据，则需要拉取表单 HTML并显示如何 Wicked 正在使用它。

If you're sending data with the above code, you'll want to pull your form HTML and show how Wicked is working with it.

您需要在 app / views / users / show.html.erb 中查看要显示的表单，不 / app / views / registrationments

You need to be looking in app/views/users/show.html.erb for the form to display, not /app/views/registrations
