尝试将项目从Rails 3.2更新到Rails 4.0。更新了一些gem之后，我遇到了一些错误和不赞成使用的内容，例如在运行“ rails s”时使用哈希调用#scope。修复后，“ rails s”有效，但是当我尝试去本地主机测试我的web应用程序时，出现此错误：
<body>
<div class="container">
<p>Select Email templates below</p>
<!-- Mr/Mrs and Customer name field start here -->
<form id="mainForm" name="mainForm">
<input type="radio" name="gender" value="Mr. " />Mr.
<input type="radio" name="gender" value="Mrs. " />Mrs.
<textarea id="textarea" placeholder="Enter customer name here" oninput="renderYourText()"></textarea>
</form>
<!-- Mr/Mrs and Customer name field end here -->
<!-- Email template drop down start here -->
<div class="button dropdown">
<select id="colorselector" onchange="renderYourText()">
<option></option>
<option value="Cancellation">Cancellation</option>
<option value="Refund">Refund</option>
</select>
</div>
<div id="Cancellation" class="colors red">
</div>
<div id="Refund" class="colors red">
</div>
</div>
<!-- Email template drop down start here -->
<!-- Text area result box start here -->
<textarea class="form-control" rows="5" id="result" name="text"></textarea>
<!-- Text area result box end here -->
<!-- Jquery and Javascript start here -->
<script>
</script>
<!-- Jquery and Javascript end here -->
</body>这是“最新更新列表”方法：
ActionView::Template::Error (wrong number of arguments (2 for 1)):

6: %th.w140
7: %tbody
8: - (list = latest_updates_list(@filter[:latest_updates_options])).each do |item|
9: %tr= latest_updates_item_helper(item)
10:
11: - if list.length == 0
app/helpers/dashboard_helper.rb:33:in `latest_updates_list'

这是“ latest_updates_list”中的第33行：
def latest_updates_list(option=nil)
client_ids = current_user.actual_client_ids
services = {}
Service.where(:client_id => client_ids).each{|s| services[s.id] = {:name => s.name, :frequency_name => s.frequency_short_text, :per_hour => s.per_hour?} }
reports = []
invoices = []
tickets = []
employees = []
list = []
case option.to_sym
when :reports
reports = Report.for_latest_updates(client_ids) if (user_admin? || user_can_report?)
when :invoices
invoices = Invoice.for_latest_updates(client_ids) if (user_admin? || user_can_invoice?)
when :tickets
tickets = Ticket.for_latest_updates(client_ids) if (user_admin? || user_can_ticket?)
when :employees
employees = Employee.for_latest_updates(current_user.filter_client_id, client_ids) if user_admin?
else

invoices = Invoice.for_latest_updates(client_ids) if (user_admin? || user_can_invoice?)
tickets = Ticket.for_latest_updates(client_ids) if (user_admin? || user_can_ticket?)
employees = Employee.for_latest_updates(current_user.filter_client_id, client_ids) if user_admin?
end
list += reports.collect do |r|
{
:date => r.updated_at,
:entity => 1,
:status_text => latest_update_report_status_text(r),
:reports_services_text => latest_updates_reports_services_text(r, r.reports_services),
:report_id => r.id}
end unless reports.empty?
list += invoices.collect do |i|
{
:date => i.updated_at,
:entity => 2,
:status_text => latest_update_invoice_status_text(i),
:invoice_reports_services_text => latest_updates_invoice_reports_services_text(services, i.reports),
:invoice_id => i.id}
end unless invoices.empty?
list += tickets.collect do |t|
{
:date => latest_update_ticket_date(t),
:entity => 3,
:status_text => latest_update_ticket_status_text(t),
:description => t.description_text,
:ticket_id => t.id}
end unless tickets.empty?
list += employees.collect do |e|
{
:date => e.updated_at,
:entity => 4,
:description => e.text_for_stream,
:employee_id => e.employee_id}
end unless employees.empty?
sorted_list = list.sort{|a, b| a[:date].to_i <=> b[:date].to_i}
list = sorted_list.reverse!
list = list.take(50)
end
这是我的Gemfile.lock
Service.where(:client_id => client_ids).each{|s| services[s.id] = {:name => s.name, :frequency_name => s.frequency_short_text, :per_hour => s.per_hour?} }
我认为这一定是一个gem问题，因为它以前一直在工作，并且我没有更改这些文件中的任何内容。

答案 0 :(得分：1)
您需要升级自己的var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth() + 1;
var curr_year = d.getFullYear();
var d1 = curr_date + "/" + curr_month + "/" + curr_year;
//alert(d1); change format date completed 12/04/2019
var date2 = new Date("04/12/2018");
var curr_date2 = date2.getDate();
var curr_month2 = date2.getMonth() + 1;
var curr_year2 = date2.getFullYear();
var d2 = curr_date2 + "/" + curr_month2 + "/" + curr_year2;
//alert(d2); // change format date completed 12/04/2018
if (d1 > d2) {
console.log("aaa");
} else {
console.log("bbb");
}宝石。
您当前安装了Arel 4.0.2，并安装了PostgresExt 2.0.0。
我看到PostgresExt 2.1.3说“修复Arel 4.0.1问题”。 https://github.com/DavyJonesLocker/postgres_ext/blob/master/CHANGELOG.md#213
您的PostgresExt版本与您安装的Rails版本不兼容。由于您最近添加了stacktrace，我来到了这个顿悟。
postgres_ext请注意，问题是PostgresExt gem中的参数数量错误。
是否注意到有关此提交的任何有趣信息？
https://github.com/DavyJonesLocker/postgres_ext/commit/4ac6184d4bbfd763044b28f98344a02cf688cca3
采用该from /Users/justin/.rvm/gems/ruby-2.1.10/gems/postgres_ext-2.0.0/lib/postgres_ext/arel/visitors/to_sql.rb:6:in `visit_Array'
方法，并使其使用两个参数而不是1。这就是问题所在。 ActiveRecord试图使用2个参数调用Arel方法，但PostgresExt已覆盖该方法以添加一些功能，并且它们的覆盖仅需要1个参数。这就是为什么这类超越核心功能的宝石使用起来有点危险。您需要良好的测试覆盖率，因为当Rails更改其gem的内部位时，它会迅速破坏此PostgresExt gem。
您还应考虑从该宝石上移走，因为它不再被维护。
我的一个同事最近向我展示了这个名为ActiveRecordExtended的宝石（奇怪的名字，考虑到它仅是Postgres，但是，哦）。我从没使用过它，所以我不能担保它，但是它似乎可以完成PostgesExt的工作，但是也得到了维护。
