我不确定我在这里做错了什么。基本上,用户只能由现有用户创建,他们只能在现有用户所在的公司中。所以我希望f.select for:company来自current_user.companies。这些模型通过表“users_companies”加入。
形式:
<div class="row">
<h3>Add User</h3>
<div class="column">
<%= simple_form_for @user do |f| %>
<%= f.input :name %>
<%= f.input :email %>
<%= f.select(:company_id, @companies.map {|company| [company,company]}) %>
<%= f.select(:role, User.roles.keys.map {|role| [role,role]}) %>
<%= f.input :password %>
<%= f.input :password_confirmation %>
<%= f.button :submit %>
<% end %>
</div>
控制器:
def new
@user = User.new
@companies = current_user.companies
end
def create
@user = User.new(params[:user].permit(:name, :company, :email, :role, :password, :password_confirmation))
authorize @user
@companies = current_user.companies
if params[:user][:password].blank?
params[:user].delete(:password)
params[:user].delete(:password_confirmation)
end
respond_to do |format|
if @user.save
format.html { redirect_to users_path, notice: 'User was successfully created.' }
else
format.html { render action: "new" }
end
end
end
架构:
ActiveRecord::Schema.define(version: 20140620190817) do
create_table "companies", force: true do |t|
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
end
create_table "groups", force: true do |t|
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
t.integer "company_id"
t.integer "tag_id"
t.integer "q_rcode_id"
t.integer "page_id"
end
create_table "pages", force: true do |t|
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
t.integer "company_id"
t.integer "group_id"
t.integer "tag_id"
t.integer "q_rcode_id"
end
create_table "q_rcodes", force: true do |t|
t.string "url"
t.datetime "created_at"
t.datetime "updated_at"
t.integer "company_id"
t.integer "group_id"
t.integer "page_id"
end
create_table "tags", force: true do |t|
t.string "url"
t.datetime "created_at"
t.datetime "updated_at"
t.integer "company_id"

end
create_table "users", force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"

t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.datetime "created_at"
t.datetime "updated_at"
t.string "name"
t.integer "role"
end
add_index "users", ["email"], name: "index_users_on_email", unique: true
add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
create_table "users_companies", id: false, force: true do |t|

好的,有一个问题。如果用户和公司通过user_company具有多对多关系,则无法确定用户何时是公司的“所有者”以及用户何时是公司的“员工”。你需要两种不同的联想。
将user_id添加到公司
将belongs_to关联添加到公司模型
class Company < ActiveRecord::Base
has_many :users, :through => :company_user #these are the employees of the company
belongs_to: :user #this is the user who owns the company
end
修复您的company_user数据,使其仅包含用户是公司员工的记录
修复公司数据,以便user_id字段包含公司所有者用户的ID
您的用户模型应该已经有公司关联
class User < ActiveRecord::Base
has_many :companies, :through => :company_user #these are the companies the user is employeed by
end

我没有改变模型就弄明白了。我最终使用了collection_select方法:
<div class="row">
<h3>Add User</h3>
<div class="column">
<%= simple_form_for @user do |f| %>
<%= f.input :name %>
<%= f.input :email %>
<%= collection_select(:user, :company_ids,
current_user.companies, :id, :name) %>
<%= f.select(:role, User.roles.keys.map {|role| [role,role]}) %>
<%= f.input :password %>
<%= f.input :password_confirmation %>
<%= f.button :submit %>
<% end %>
</div>
</div>
从控制器中取出定义,留下:
def create
@user = User.new(params[:user].permit(:name, :company_ids, :email, :role, :password, :password_confirmation))
authorize @user
if params[:user][:password].blank?
params[:user].delete(:password)
params[:user].delete(:password_confirmation)
end
respond_to do |format|
if @user.save
format.html { redirect_to users_path, notice: 'User was successfully created.' }
else
format.html { render action: "new" }
end
end
end
