当我提交表单时,它会创建新的Outfitter,但它不会创建新用户。在日志中它表示“未经许可的参数:utf8,authenticity_token,first_name,last_name,email,password,password_confirmation,commit'
模态html :(模态在application.html.erb。页面是localhost:3000 / pages / index)

首先,如果要构建映射到模型的表单,我建议使用rails form_for或simple_form gem。
使用上述任何一种方法都可以使用fields_for:users,它们会将users_attributes发送给控制器。
您还需要在Outfitter模型中使用accepts_nested_attributes_for:用户。(http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html)
如果您使用的是Rails 3或Rails 4,则会有一个额外的步骤:
Rails 4: 您需要在强参数(http://edgeapi.rubyonrails.org/classes/ActionController/StrongParameters.html)
上允许users_attributesparams.require(:outfitter).permit(users_attributes: [])
Rails 3:您必须将:users_attributes添加到您的模型的attr_accessible
class Outfitter < ActiveRecord::Base
attr_accessible :users_attributes
accepts_nested_attributes_for :users_attributes
...
end
希望这可以帮到你。
当使用简单表单时,您需要传递某个类的实例,以便它可以为该特定类构建for并将表单变量传递给该块:
# @outfitter will be the one you instantiated your new action
<%= simple_form_for @outfitter do |f| %>
#form inputs go here, see next code block for more info
<% end %>
简单表单将采用您的@outfitter
实例,检查其记录是否已保存到数据库中,并将定义用于根据该数据提交数据的URL和方法。
如果@outfitter
是新记录(这是您的情况)
OutfittersController
创建操作如果@outfitter
不是新记录(已保存到数据库中,现在正在更新)
OutfittersController
更新操作要在simple_form块内创建输入,请执行以下操作:
<%= simple_form_for @outfitter do |f| %>
# f - is the form object
# input - is the method called on the form to create the input
# :name - is the attribute name that will be mapped to this input
# you can only create inputs for the attributes in your class
<%= f.input :name %>
<%= f.input :address %>
<% end %>
要使用简单表单创建嵌套表单,您必须执行以下操作
<%= simple_form_for @outfitter do |f| %>
# calling f.simple_fields_for will ensure simple_form knows the users form is nested under outfitter form
<%= f.simple_fields_for :users do |user_form| %>
# user_form is the form object nested under outfitters form
# every input method inside this block should be called on user_form
<%= user_form.input :name %>
<%= user_form.input :address %>
<% end %>
<% end %>
您的完整内容如下:
<%= simple_form_for @outfitter do |f| %>
<div class="modal-message">
<p>
# input_html is used to parse attributes to be added to the input
<%= f.input :name, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<p>
<%= f.input :address, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<p>
<%= f.input :business_phone, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<%= f.simple_fields_for :users do |user_form| %>
<p>
<%= f.input :first_name, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<p>
<%= f.input :last_name, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<p>
<%= f.input :email, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<p>
<%= f.input :password, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<p>
<%= f.input :password_confirmation, input_html: { class: 'input-txt rounded-2px' } %>
</p>
<% end %>
<div class="button rounded-2px trans-all">
<%= f.submit 'Signup', class: 'send-btn rounded-2px trans-all' %>
</div>
<% end %>
你可以用简单的形式做更多的事情,确保你去他们的github回购并阅读文档。
