当我尝试从我的表创建/编辑或销毁联系人时出错。
当我尝试创建/编辑时，我有：
ContactController中的ActiveRecord :: StatementInvalid #create
PG :: UndefinedFunction：ERROR：函数get_xmlbinary（）不存在 第1行：SELECT（get_xmlbinary（）=＆＃39; base64＆＃39;）^提示：无功能 匹配给定的名称和参数类型。您可能需要添加 显式类型转换。 QUERY：SELECT（get_xmlbinary（）=＆＃39; base64＆＃39;） 语境：PL / pgSQL函数hc_contact_status（）在IF：INSERT处的第3行 INTO＆＃34;联系＆＃34; （＆＃34;姓氏＆＃34;，＆＃34;名字＆＃34;，＆＃34;名称＆＃34;，＆＃34;手机＆＃34;，＆＃34;电子邮件＆＃34;） 价值（1美元，2美元，3美元，4美元，5美元）退货＆＃34; id＆＃34;
当我尝试删除时：
ContactController中的ActiveRecord :: StatementInvalid #create
PG :: UndefinedFunction：错误：函数hstore（联系人）不存在 第1行：SELECT hstore（OLD。） - excluded_cols ^提示：无功能 匹配给定的名称和参数类型。您可能需要添加 显式类型转换。 QUERY：SELECT hstore（OLD。） - excluded_cols 语境：PL / pgSQL函数hc_contact_logger（）第18行分配： 删除＆＃34;联系＆＃34;在哪里＆＃34;联系＆＃34;。＆＃34; id＆＃34; = $ 1
我跟着它guide添加＆＃34; hstore＆＃34;到我的application_db但显示ERROR: extension "hstore" already exists
我正在使用现有数据库（Salesforce）。我使用命令行rails generate scaffold contact获取模型控制器和视图，我可以在浏览器上显示数据库的内容。
contact_controller.rb：
class ContactController < ApplicationController
before_action :set_contact, only: [:show, :edit, :update, :destroy]
# GET /contacts
# GET /contacts.json
def index
@contact = Contact.all
end
# GET /contacts/1
# GET /contacts/1.json
def show
end
# GET /contacts/new
def new
@contact = Contact.new
end
# GET /contacts/1/edit
def edit
end
# POST /contacts
# POST /contacts.json
def create
@contact = Contact.new(contact_params)
respond_to do |format|
if @contact.save
format.html { redirect_to @contact, notice: 'Contact was successfully created.' }
format.json { render :show, status: :created, location: @contact }
else
format.html { render :new }
format.json { render json: @contact.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /contacts/1
# PATCH/PUT /contacts/1.json
def update
respond_to do |format|
if @contact.update(contact_params)
format.html { redirect_to @contact, notice: 'Contact was successfully updated.' }
format.json { render :show, status: :ok, location: @contact }
else
format.html { render :edit }
format.json { render json: @contact.errors, status: :unprocessable_entity }
end
end
end
# DELETE /contacts/1
# DELETE /contacts/1.json
def destroy
@contact.destroy
respond_to do |format|
format.html { redirect_to @contact, notice: 'Contact was successfully destroyed.' }
format.json { head :no_content }
end
end
#contact_url
private
# Use callbacks to share common setup or constraints between actions.
def set_contact
@contact = Contact.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def contact_params
params.require(:contact).permit(:name, :lastname, :firstname, :phone, :email)
end
end
它能是什么？不要犹豫，询问您是否需要其他文件
编辑：我在PSQL上找到了它：
插入或删除或更新后hc_contact_logtrigger salesforce.contact FOR EACH ROW WHEN（get_xmlbinary（）:: text = ＆＃39; base64＆＃39; :: text）EXECUTE PROCEDURE salesforce.hc_contact_logger（）
hc_contact_status_trigger在INSERT或UPDATE ON之前 salesforce.contact FOR EACH ROW EXECUTE PROCEDURE salesforce.hc_contact_status（）

答案 0 :(得分：0)
你需要包括＆＃34; public＆＃34;架构到schema_search_path到database.yml
default: &default
...........
schema_search_path: "salesforce,public"
Connect在数据库的get_xmlbinary模式中创建一个名为public的函数，它将其用作同步过程的一部分。如果您从public中删除search_path架构，则Connect将无法找到该功能，并且同步将失败。
