rails深度嵌套的form_for不能保存两次
rails深度嵌套的form_for不能保存两次
提问于 2017-03-10 23:08:26
我有一个表格，球队可以注册一个锦标赛。当我第一次保存表单时，表单会按预期保存& routes，但是如果我返回到root_path并重复注册团队的过程，表单根本不会保存(单击"Submit“按钮什么也不做)。
我的感觉是，原来的保存中有一些东西挂在那里，阻止了一个新的保存发生，但我不能确定它是什么。代码如下，希望它是足够的。
(routes.rb)
root 'tournaments#index'
resources :tournaments do
resources :teams do
resources :players, :only => [:new, :create]
end
end(型号)
class Tournament < ApplicationRecord
has_many :teams
has_many :players, :through => :teams
accepts_nested_attributes_for :teams
accepts_nested_attributes_for :players
end
class Team < ApplicationRecord
belongs_to :tournament, required: false
has_many :players
accepts_nested_attributes_for :players
end
class Player < ApplicationRecord
belongs_to :team, required: false
has_one :tournament, :through => :team
end(tournaments_controller.rb)
def index
@tournaments = Tournament.all
end
def show
@tournament = Tournament.find(params[:id])
end
def new
@tournament = Tournament.new
end
def create
@tournament = Tournament.new(tournament_params)
if @tournament.save
flash[:notice] = "#{@tournament.name} saved."
redirect_to root_path
else
render :new
end
end
private
def tournament_params
params.require(:tournament).permit(:name, :deadline, :divisions, :info, :payment, :tournament_date, team_attributes: [:name, :division, :contact_email, :contact_name])
end(teams_controller.rb)
def create
@team = Team.new(team_params)
if @team.save
flash[:notice] = "Team Registered."
redirect_to tournament_team_path(params[:tournament_id], @team.id)
else
redirect_to new_tournament_team_path(params[:tournament_id])
end
end
def new
@tournament = Tournament.find_by_id(params[:tournament_id])
@team = Team.new
8.times do
@team.players.build
end
end
def show
@tournament = Tournament.find(params[:tournament_id])
@team = Team.find(params[:id])
end
private
def team_params
params.require(:team).permit(:name, :tournament_id, :division, :contact_name, :contact_email, players_attributes: [ :name, :gender, :referee ])
end从tournaments#show页面到teams#new操作的入口链接(此操作有效...只要它链接到正确的页面)
<%= link_to(new_tournament_team_path(params[:id])) do %><div class="rounded_btn"><h3>Register Team</h3></div><% end %>(team/new.html.erb)-这是不起作用的表单。我应该使用分式，但我想让它开始工作。
<main class="long_page">
<h1 class="tournament_name"><%= @tournament.name %></h1>
<h3 class="tournament_name">Team Registration</h3>
<section style="align-items: baseline;">
<div class="rounded_box">
<%= form_for [@tournament, @team] do |f| %>
<%= f.hidden_field :tournament_id, :value => @tournament.id %>
<div>
<p>
<%= f.label :division, "Division: " %>
<%= f.select :division, options_for_select([["Mixed", "mixed"], ["Mens", "mens"]]) %>
</p>
<p>
<%= f.text_field :name, required: '' %>
<label alt='Team Name' placeholder='Team Name'></label>
</p>
<p>
<%= f.text_field :contact_name, required: '' %>
<label alt='Contact Person' placeholder='Contact Person'></label>
</p>
<p>
<%= f.text_field :contact_email, required: '' %>
<label alt='Contact Email' placeholder='Contact Email'></label>
</p>
<div class="clear"></div>
</div>
<%= f.fields_for :players do |builder| %>
<div>
<%= builder.text_field :name, required: '' %>
<%= builder.select :gender, options_for_select([["Male", "male"], ["Female", "female"]]) %>
<%= builder.select :referee, options_for_select([["No", "no"], ["Yes", "yes"]]) %>
</div>
<% end %>
</div>
<div class="btn_holder">
<p>
<%= f.submit 'Submit Team', :class => 'rounded_btn' %>
</p></div>
<% end %>
</div>
</section>这将生成以下HTML输出：

我从我的/views/application.erb.html文件中删除了<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %> &现在函数似乎可以工作了。
