我真的不知道错在哪里.请帮忙.
提前致谢！
解决方案
啊，我自己解决了问题.对于那些在那里的人，这里是解决方案:-
从 development.log 中，我注意到 "profile" =>{}.它应该是 "profile_attributes" =>{} 所以我将 edit.html.erb 表单修改为:-
<%= form_for :user, url: admin_user_path(@user), 方法: :patch do |f|％＞<div class="form-group"><%= f.label :username %><br>形式控制"％>
<%= f.fields_for :profile_attributes, @user.profile do |profile|％＞<div class="form-group"><%= profile.label :full_name %><br>形式控制"％>
<%结束%><div class="form-group"><%= f.submit "Save", :class =>btn btn-primary"%>
<%结束%>
然后，我在 development.log 中收到另一个错误:-
ActiveRecord::RecordNotSaved(无法删除现有的关联配置文件.记录在其外键设置为 nil 后无法保存.):
所以，我再次更新我的 user.rb 以具有:-
class User { :case_sensitive =>错误的 }结尾
This question has many times asking by others user but still not solved my problem here. Im having a problem with my rails apps where error "Unpermitted Parameters: profile" appear.
user_controller.rb
class Admin::UsersController < ApplicationController
before_filter :set_user, only: [:edit, :update]
before_filter :store_location, only: [:index]
before_filter :require_admin
def edit
if @user
render
else
redirect_to admin_users_path, notice: "User profile not found."
end
end
def update
# Rails.logger.debug "===> (1)"
if @user.update(user_params)
redirect_to edit_admin_user_path, notice: "#{@user.profile.full_name} account has been updated."
else
render 'edit'
end
end
private
def set_user
@user = User.find(params[:id])
end
def user_params
params.require(:user).permit(:id, :username, :email, profile_attributes: [:user_id, :full_name])
end
end
edit.html.erb
<%= form_for :user, url: admin_user_path(@user), method: :patch do |f| %>
<div class="form-group">
<%= f.label :username %><br>
<%= f.text_field :username, :class => "form-control" %>
</div>
<%= f.fields_for :profile, @user.profile do |profile| %>
<div class="form-group">
<%= profile.label :full_name %><br>
<%= profile.text_field : full_name, :class => "form-control" %>
</div>
<% end %>
<div class="form-group">
<%= f.submit "Save", :class => "btn btn-primary" %>
</div>
<% end %>
User.rb
class User < ActiveRecord::Base
has_one :profile
accepts_nested_attributes_for :profile #, update_only: true, allow_destroy: true
validates :username, :uniqueness => { :case_sensitive => false }
end
Profile.rb
class Profile < ActiveRecord::Base
belongs_to :user
validates_presence_of :user_id
validates_presence_of :full_name
end

I really don't know where is the mistake. Please help.
Thanks in advance!
解决方案
Ah, I solved my own question. For those out there, here is the solution:-
From development.log, i notice something that is "profile" => {}. It SHOULD BE "profile_attributes" => {} so I modified my edit.html.erb form to:-
<%= form_for :user, url: admin_user_path(@user), method: :patch do |f| %>
<div class="form-group">
<%= f.label :username %><br>
<%= f.text_field :username, :class => "form-control" %>
</div>
<%= f.fields_for :profile_attributes, @user.profile do |profile| %>
<div class="form-group">
<%= profile.label :full_name %><br>
<%= profile.text_field :full_name, :class => "form-control" %>
</div>
<% end %>
<div class="form-group">
<%= f.submit "Save", :class => "btn btn-primary" %>
</div>
<% end %>
Then, I got another error said in development.log:-
ActiveRecord::RecordNotSaved (Failed to remove the existing associated profile. The record failed to save after its foreign key was set to nil.):
So again, I update my user.rb to have:-
class User < ActiveRecord::Base
has_one :profile
accepts_nested_attributes_for :profile, update_only: true, allow_destroy: true
validates :username, :uniqueness => { :case_sensitive => false }
end
