だから私はアクティブモデルを使用してRubyonRails(1.9.3)のマルチステップフォームに取り組んでおり、railscast#217と#219の両方に従っていて、検証に問題があります。問題は、属性フィールドが空白ではない場合でもエラーがスローされます
1 error prohibited this wizard from being saved:
Validationattr can't be blank
私はそれが節約されるべきだとは信じていませんが、これはエラーと関係があるかもしれません。(フォームジェムは使用できません。自分で作成する必要があります)さらに情報が必要な場合はお知らせください。喜んで提供させていただきます。
私のコントローラーコード-(contollers / awizard_controller.rb)
class AwizardController < ApplicationController
def new
# New Asset Wizard
@wizard = Awizard.new(id: 1)
# Set session variable as initial step
session[:wizard_step] = @wizard.current_step
end
def update
@wizard = Awizard.new(id: 1) unless !@wizard.nil?
@wizard.current_step = session[:wizard_step] unless nil
if @wizard.valid?
if params[:back_button]
@wizard.previous_step
elsif @wizard.last_step?
@wizard.save if @wizard.all_valid?
else
@wizard.next_step
end
session[:wizard_step] = @wizard.current_step
end
if @wizard.changed?
render 'form'
else
@wizard.save
end
end
end
私のawizardモデル-(models / awizard.rb)
class Awizard < Wizard
validates :validationattr, :presence => true
attr_accessor :validationattr
def steps
%w[validate_schedule validate_assets save_assets]
end
end
私のウィザードモデル-(models / widget.rb)
class Wizard
include ActiveModel::Validations
include ActiveModel::Conversion
include ActiveModel::Dirty
include ActiveModel::Naming
#This class is used to manage the wizard steps using ActiveModel (not ActiveRecord)
attr_accessor :id
attr_writer :current_step #used to write to current step
define_attribute_methods [:current_step] #used for marking change
def initialize(attributes = {})
attributes.each do |name, value|
send("#{name}=", value)
end
end
def current_step
@current_step || steps.first
end
def steps
%w[]
end
def next_step
current_step_will_change! #mark changed when moving stepped
self.current_step = steps[steps.index(current_step)+1] unless last_step?
end
def previous_step
current_step_will_change! #mark changed when moving stepped
self.current_step = steps[steps.index(current_step)-1] unless first_step?
end
def first_step?
current_step == steps.first
end
def last_step?
current_step == steps.last
end
def all_valid?
steps.all? do |step|
self.current_step = step
valid?
end
end
def step(val)
current_step_will_change!
self.current_step = steps[val]
end
def persisted?
self.id == 1
end
end
私の意見- (/views/awizard/_form.html.erb)
<%= content_for :awizard_form do%>
<%= form_for(@wizard) do |f| %>
<%= render "#{@wizard.current_step}_step", :f => f %>
<%= f.submit "Previous", :name => "back_button" unless @wizard.first_step? %>
<%= f.submit "Continue", :name => "step" unless @wizard.last_step? %>
<% end %>
<% end %>
(/views/awizard/_step1.html.erb)
<div class="field">
<%= f.label :validationattr %><br />
<%= f.text_field :validationattr %>
</div>
(/views/awizard/_step2.html.erb)
<div class="field">
<%= f.label 'Step2' %><br />
</div>
(/views/awizard/_step3.html.erb)
<div class="field">
<%= f.label 'Step3' %><br />
</div>
