Question

我无法在新模型中输入数据。

我创建了一个新模型，以便可以将用户分配给关联公司。

我有一个Users，Affiliates和UserAffiliates模型。

UserAffiliates ：

  belongs_to :users
  belongs_to :affiliates

用户：

  has_and_belongs_to_many :user_affiliate
  has_and_belongs_to_many :affiliate, through: :user_affiliate, optional: true

会员：

  has_many :user_affiliates
  has_many :users, through: :user_affiliates

它是如何工作的，一个会员可以有很多用户，但是一个用户永远只有一个会员。然后，我在UserAffiliates表中有一个佣金列，以根据每个用户设置佣金。

我创建了此表单，但它似乎不起作用（这是由于<% @users.each do |user| %>遍历表中的每个用户所致：

<%= form_for user, remote: true do |f| %>
  <% f.fields_for :user_affiliates,  remote: true do |f| %>
    <%= f.text_field :affiliate_id, class: "form-control"  %>
  <%= f.submit "Add Affiliate", data: {confirm: "Are you sure?"}, class: "btn btn-light" %>
  <% end %>
<% end %>

我收到此错误：

Parameters: {"utf8"=>"✓", "user"=>{"user_affiliates"=>{"affiliate_id"=>"1"}}, "commit"=>"Add Affiliate", "id"=>"2"}
  User Load (0.7ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = $1 LIMIT $2  [["id", 2], ["LIMIT", 1]]
  ↳ app/controllers/users_controller.rb:58
Completed 500 Internal Server Error in 62ms (ActiveRecord: 6.4ms)



ArgumentError (wrong number of arguments (given 0, expected 1..2)):

app/controllers/users_controller.rb:88:in `[]'
app/controllers/users_controller.rb:88:in `user_params'
app/controllers/users_controller.rb:61:in `block in update'
app/controllers/users_controller.rb:60:in `update'

用户控制器参数：

 def user_params
    params.require(:user).permit(:name, :approved, :seller, :buyer, :admin, :stripe_account, :email, :password, :password_confirmation, :role, :affiliate_id, :affiliate_ids [], :user_affiliates, :commission)
 end

我的表格有误吗？

我希望能够将表中的用户列出为user.admin，具有一个文本字段，然后输入affiliate_id，然后将user_id和affiliate_id输入到UserAffiliate表中。我还希望能够添加user.admin和Affiliate都可以更改的佣金率。

如何正确执行此操作？

更新：

我已修正参数，但仍然存在错误：

参数：

def user_params
       params.require(:user).permit(:name, :approved, :seller, :buyer, :admin, :stripe_account, :email, :password, :password_confirmation, :role, :affiliate_id, :user_affiliates, :affiliate, :commission, affiliate_ids: [])
end

错误：

ActionController::UnknownFormat (ActionController::UnknownFormat):

app/controllers/users_controller.rb:60:in `update'

我试图在所有控制器，模型和形式中将其更改为user_affiliate（非脉冲）和复数形式。我需要对用户控制器上的更新进行任何操作吗？

用户控制器更新：

  def update
   @user = User.find(params[:id])
   # @affiliate = current_affiliate
   respond_to do |format|
     if @user.update(user_params) # <- you'll need to define these somewhere as well
       if @user.admin?
         format.html { redirect_to '/admin/users', notice: "yahoo" }
         format.json { render json: @user }
       # elsif @affiliate
       #     format.html { redirect_to '/a/clients', notice: "yahoo" }
       #     format.json { render json: @user }
       else
         format.html { render :edit }
         format.json { render json: { errors: @user.errors }, status: :unprocessable_entity }
       end
     end
   end

has_many_and_belongs_to：param到：param
