Rails没有收到http发布请求参数

Question

I'm working on a simple one-page website on Ruby on Rails that has a 'Contact Us' form. It has 3 fields - name, e-mail and text -, and a submit button. In theory, after filling up these forms and clicking the button, the user will receive an email with the confirmation of the request. The controller basically has only one method that writes the data in the DB and after successful saving sends an email.

The problem is that the controller doesn't receive the parameters(name, email and text) and raises an exception: ActionController::ParameterMissing (param is missing or the value is empty: application)

I'm sure that the data is sent. Here's the log:

Started POST "/" for 127.0.0.1 at 2015-07-23 20:25:08 +0300
Processing by ApplicationsController#create as HTML
  Parameters: {"name"=>"Foo Bar", "email"=>"foobar@example.com", "text"=>"qwerqwepoiqtwporihtqwojbr[sdfzxc"}
Completed 400 Bad Request in 381609ms

Source code of the controller:

class ApplicationsController < ApplicationController

  skip_before_filter :verify_authenticity_token, :if => Proc.new { |c| c.request.format == 'text/html' }

  def new
    @request = Application.new
  end

  def create
    @request = Application.new(application_params)
    if @request.save
      ApplicationMailer.request_confirmation(@request).deliver_now
      flash[:info] = 'Your application has been registered! Check your e-mail!'
    else
      flash[:alert] = 'Oops! Your application was not registered!'
    end
  end

  private
    def application_params
      params.require(:application).permit(:name, :email, :text)
    end
end

Source code of the Application model:

class Application < ActiveRecord::Base
  before_save{
    self.email.downcase!
  }
  validates(:name, presence: true, length: { maximum: 50 })
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i
  validates(:email, presence: true, length: {maximum: 255},
            format: {with: VALID_EMAIL_REGEX})
  validates(:text, presence: true)
end

Does anybody have any idea where is the problem and how to solve it?

Thank you in advance.

UPD: Form code:

<form method="post" class="form-horizontal col-md-8" name="application" id="applyForm">
        <div class="row" id="credentials">
          <div class="col-sm-6">
            <div class="input-group form-group" id="full_name">
              <span class="input-group-addon" id="basic-addon1"><i class="fa fa-user"></i></span>
              <input type="text" name="name" class="form-control" placeholder="Your name" aria-describedby="basic-addon1" id="name">
            </div>
          </div>
          <div class="col-sm-6">
            <div class="input-group form-group" id="email">
              <span class="input-group-addon" id="basic-addon1"><i class="fa fa-envelope"></i></span>
              <input type="text" name="email" class="form-control" placeholder="E-mail" aria-describedby="basic-addon1" id="email">
            </div>
          </div>
        </div>
        <div class="row" id="comment-area">
          <div class="col-sm-12" id="comment">
            <textarea class="form-control" name="text" rows="10" placeholder="Please describe your system" id="text"></textarea>
          </div>
        </div>
        <div class="row" id="submit-button">
          <button type="submit" class="btn btn-default"><i class="fa fa-rocket"></i>Send message</button>
        </div>
    </form>

Answer 1

Your params are not coming from application , for a quick fix just change application_params to below

def application_params
  params.permit(:name, :email, :text)
end
