所以我一直在使用Active模型在ruby on rails(1.9.3)上进行多步骤表单,同时遵循railscast#217和#219,并且遇到路由到我的表单中的后续步骤的问题/ awizard / new to / awizard / 1希望有人可以帮助我。 (我不能使用表单gem并且必须自己编写)我认为这是一个路由类型问题(我没有使用我给模型的id,但我无法弄清楚我应该在哪里使用它)一点帮助会非常感谢!
我的控制器代码 - (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
def show
render 'form'
end
end
我的模型 - (models / awizard.rb)
class AWizard
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[step1 step2 step3] #make list of steps (partials)
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
def save
#will do later
end
end
我的观点 的(/视图/ 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 %>
(适用/视图/ awizard / _step1.html.erb)
<div class="field">
<%= f.label 'Step1' %><br />
</div>
(适用/视图/ awizard / _step2.html.erb)
<div class="field">
<%= f.label 'Step2' %><br />
</div>
(适用/视图/ awizard / _step3.html.erb)
<div class="field">
<%= f.label 'Step3' %><br />
</div>

答案 0 :(得分:1)
错误消息指出,form
目录中没有名称为awizard
的部分内容。你应该坚持关于部分的Rails约定 - 部分文件总是以下划线为前缀。
在您的情况下,请尝试将form.html.erb
重命名为_form.html.erb
。
编辑:你可以尝试像这样渲染你的部分
render :partial => 'awizard/form'
