Question

这可能是显而易见的，但我需要另外一双眼睛来获得它。单击我的“提交”按钮不会产生任何结果（不是重定向，只是没有）。

Rails 4应用程序是机场附近停车场的预订系统。这就是一切：

的routes.rb ：

Parkix::Application.routes.draw do

...
resources :books
....

root to: "books#index"

end

books_controller.rb ：

class BooksController < ApplicationController

def index
    @book = Book.new
end

def create
    @book = Book.new params[:book]
    render "index"
end

end

book.rb （模特）：

class Book < ActiveRecord::Base

attr_accessor :airport, :start_date, :start_time, :end_date, :end_time

belongs_to :park
belongs_to :user
has_many :prices, through: :parks

before_validation :generate_dates

private

def generate_dates
    self.start = Time.strptime "#{self.start_date} #{self.start_time}", "%d/%m/%Y %H:%M"
    self.end = Time.strptime "#{self.end_date} #{self.end_time}", "%d/%m/%Y %H:%M"
end

end

书籍/ index.html.erb ：

<%= form_for Book.new, url: { action: "create" }, method: :post do |f| %>

<%= f.text_field :airport, placeholder: "Airport" %>
<%= f.text_field :start_date, placeholder: "Start date" %>
<%= f.text_field :start_time, value: "10:00", placeholder: "Start time" %>
<%= f.text_field :end_date, placeholder: "End date" %>
<%= f.text_field :end_time, value: "10:00", placeholder: "End time" %>
<%= f.text_field :count_people, placeholder: "Count people" %>
<%= f.submit "Search", class: "btn btn-primary" %>

<% end %>

正如我之前所说，当我点击提交按钮时没有任何反应。有没有人有想法？

提前致谢。

Answer 1

感谢大家的帮助，但这是由于JS捕获表单提交事件。不是Ruby问题。

我将结束这个话题。

感谢。

确定第一步，你不需要写url，rails可以推断它。所以

<%= form_for Book.new do |f| %>
  <%= f.text_field :airport, placeholder: "Airport" %>
  <%= f.text_field :start_date, placeholder: "Start date" %>
  <%= f.text_field :start_time, value: "10:00", placeholder: "Start time" %>
  <%= f.text_field :end_date, placeholder: "End date" %>
  <%= f.text_field :end_time, value: "10:00", placeholder: "End time" %>
  <%= f.text_field :count_people, placeholder: "Count people" %>
  <%= f.submit "Search", class: "btn btn-primary" %>
<% end %>

第2步，最重要的是，你没有保存它

def create
   @book = Book.new params[:book]
   @book.save!
   render "index"
end

或

def create
   @book = Book.create! params[:book]
   render "index"
end

提交Rails form_for时没有任何反应
