我无法在 _form.html.erb 中创建的部分日期中保存日期。部分文件名为 _education.html.erb 。这就是它当前在_form.html.erb中作为<%= render partial:'clients/education' %>声明的内容。我无法弄清楚我错过了什么。我认为它可能会将partial设置为局部变量，但我不确定。当我删除部分时，表单工作正常。
_education.html.erb

以下是客户表格的控制器。我确保将ed_id添加到params中，因为它在client.rb中有belongs_to，在ed.rb中有has_many
class ClientsController < ApplicationController
before_action :authenticate_user!
before_action :set_client, only: [:show, :edit, :update, :destroy]
# GET /clients
# GET /clients.json
def index
@clients = Client.all.uniq.order("created_at DESC")
@clients_count = Client.uniq.count
end
# GET /clients/1
# GET /clients/1.json
def show
@notes = Note.where(client_id: @client.id) #Where a note belong to the current account
end
# GET /clients/new
def new
@client = Client.new
end
# GET /clients/1/edit
def edit
end
# POST /clients
# POST /clients.json
def create
@client = Client.new(client_params)
respond_to do |format|
if @client.save
format.html { redirect_to @client, notice: 'Client was successfully created.' }
format.json { render :show, status: :created, location: @client }
else
format.html { render :new }
format.json { render json: @client.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /clients/1
# PATCH/PUT /clients/1.json
def update
#if params[:remove_image]
#@client.remove_image!
@client.save
#end
respond_to do |format|
if @client.update(client_params)
format.html { redirect_to @client, notice: 'Client was successfully updated.' }
format.json { render :show, status: :ok, location: @client }
else
format.html { render :edit }
format.json { render json: @client.errors, status: :unprocessable_entity }
end
end
end
# DELETE /clients/1
# DELETE /clients/1.json
def destroy
@client.destroy
respond_to do |format|
format.html { redirect_to clients_url, notice: 'Client was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_client
@client = Client.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def client_params
params.require(:client).permit(:firstName, :lastName, :dob, :gender_id, :remove_image, :insurance_id, :state_id, :ed_id, :rsource_id, :image, :race_id, :employment_id, :comments, :email, :phone, :address, :city, :state, :zipcode)

end
以下是表单的简短版本。
<%=form_for(@client, html: {class: "pure-form pure-form-stacked", multipart:true}) do |f| %>
<% if @client.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@client.errors.count, "error") %> prohibited this client from being saved:</h2>
<ul>
<% @client.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<!-- beginning of rails code -->
<form class="pure-form pure-form-stacked">

答案 0 :(得分：2)
您需要将本地文件传递给_education partial：
<%= render partial:'clients/education', locals: {f: f} %>
然后在你的_education partial中，你不需要另一个form_for声明;继续使用<%= f.collection_select...等
希望这有帮助！ ： - ）
