Rails添加「屬於」到「有很多」和存儲結果

Question

我是新來的Stackoverflow &鐵軌，但你好！

我環顧四周，無法把所有東西都放在一起。

我正在創建一個儀表板，允許用戶添加一個新的客戶端與4個不同的領域。然後允許用戶將8個不同的字段添加到特定的客戶端。但是，我很努力地將一個項目添加到客戶端並讓它顯示出來。我已經將我的代碼公開在：https://github.com/JackStovell/revenue-dashboard。

請將我的代碼撕成片段&告訴我哪裏出錯了，我可以調整它！

感謝

下面是一些片段：

項目型號：

class Project < ActiveRecord::Base 
belongs_to :client 
end 

客戶端模式

class Client < ActiveRecord::Base 
has_many :projects 
end 

項目控制器

class ProjectsController < ApplicationController 
skip_before_action :verify_authenticity_token 
before_action :set_project, only: [:show, :edit, :update, :destroy]

end 

private

    @project = Project.find(params[:id]) 
end 

# Never trust parameters from the scary internet, only allow the white list through. 
def project_params 
    params.require(:project).permit(:id, :name, :jobNumber, :status, :billing, :cost, :income) 
end 


end

代碼：

clients_controller.rb

def new 
    @client = Client.new 
    @project = @client.projects.build 
end 

def create 
    @client = Client.new(client_params) 
    @client.save 
end 

def client_params 
    params.require(:client).permit(:id, :client_name, ..., 
    project_attributes: [:name, ...]) 
end 

項目/ _form.html.erb

<%= f.label :clientName %> 
<%= f.text_field :clientName"%>

<%= f.fields_for :projects do |project| %> 
    <%= project.label :name %> 
    <%= project.text_field :name%>
