我在页面中有两个表格，如下所示，甚至包括那些未打印的错误打印部分
<code>
<div id="tabs-2">
<% if @user.personal %>
<h2>Personal Details</h2>
<div class="image"><%= image_tag (@user.personal.avatar_url(:thumb))if @user.personal.avatar? %></div>
<b>First Name</b>: <%= @user.personal.first_name %><br>

<b>Gender</b>: <%= @user.personal.gender %><br>
<b>Category</b> <%= Category.find(@user.personal.category_id).category %><br>
<b>Blood Group</b>: <%= @user.personal.blood_group %><br>
<b>Fathers_name</b>: <%= @user.personal.fathers_name %><br>
<b>Mothers_name</b>: <%= @user.personal.mothers_name %><br>
<% else %>
<%= form_for([@user, Personal.new]) do |f| %>
<% if @user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@user.errors.count, "error") %> prohibited this candidate from being saved:</h2>
<ul>
<% @user.personal.errors.full_messages.each do |message| %>

<% end %>
</ul>
</div>
<% end %>
<p>

</p>
<p>

<%= f.text_field :middle_name %>

</p>
<p>
<%= f.label :date_of_birth, "Date of Birth" %><br/>
<%= f.date_select :date_of_birth, start_year: 1985, end_year: 1999 %>
</p>
<p>
<%= f.label :gender %><br/>
<%= f.select :gender, options_for_select(%w[M F O]) %>
</p>

<%= select("personal", "category_id", Category.all.collect {|c| [c.category, c.id]}) %>
</p>
<p>
<%= f.label :avatar %>
<%= f.file_field :avatar %>
</p>
<p><%= f.submit "Submit", data: {confirm: "Are you sure information once submitted cant be modified ?"} %></p>
<% end %>
<% end %>
</code>
这是第一个进入
的表格app/views/user_dashboard/home.html.erb
我无法弄清楚为什么在验证失败时不会打印错误 出现在personal.rb
class Personal < ActiveRecord::Base
# every personal information belongs to a particular user
belongs_to :user
# carrierwave uploader
mount_uploader :avatar, AvatarUploader
# validations
validates :first_name, presence: true, length: { maximum: 24}
validates :middle_name, length: { maximum: 24}
validates :last_name, presence: true, length: { maximum: 24}
validates :date_of_birth, presence: true
validates :gender, presence: true, length: { maximum: 1}
validates :category_id, presence: true
validates :blood_group, presence: true, length: { maximum: 2}
validates :fathers_name, presence: true, length: { maximum: 24}
validates :mothers_name, presence: true, length: { maximum: 24}
validates :avatar, presence: true
end
这是personals_controller.rb
class PersonalsController < ApplicationController
before_action :set_personal, only: [:show, :edit, :update, :destroy]
# This helps to create personals
def create
@user = current_user
@personal = @user.create_personal(personal_params)
redirect_to home_path
end
private
# Never trust parameters from the scary internet, only allow the white list through.
def personal_params
params.require(:personal).permit(:user_id, :category_id, :avatar, :date_of_birth, :gender, :blood_group, :fathers_name, :mothers_name, :address_present, :first_name, :last_name, :middle_name)
end
end

有一种更清洁的方法可以做到这一点。在你的控制器方法中（假设它在家）你可以这样做：
def home
@user = User.find(params[:id]) #your logic to find user
@personal = @user.build_personal #assuming you have user has_one personal association
end
然后以您的形式
<%= form_for([@user, @personal]) do |f| %>
<% if @personal.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@personal.errors.count, "error") %> prohibited this candidate from being saved:</h2>
<ul>
<% @personal.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<% end %>
<强>更新
在您的创建操作中（假设此表单需要创建操作），您需要具有以下内容：
def create
@user = User.find(params[:id]) # logic to find user
@personal = @user.build_personal(personal_params)
respond_to do |format|
if @personal.save
format.html { redirect_to @personal }
else
format.html { render :action => "home" }
end
end
end
private
def personal_params
params.require(:personal).permit(:your_attributes)
end
<强>更新
如果您的表单通过了验证，则create_personal将只创建您的记录，因为它不会直接转到下面的步骤，即重定向到home_path，因此没有错误
您甚至可以在日志中看到它

答案 1 :(得分：0)
class PersonalsController < ApplicationController
def create
@user = current_user
@personal = @user.build_personal(personal_params)
if @personal.save
flash[:notice] = "success"
else
flash[:alert] = @personal.errors.full_messages.each{|e|}
end
redirect_to home_path
end
end
这是答案吗？
