我有一个rails应用程序(rails 5).在开发中,当我使用时,一切都有效

rails console

并输入一条指令,例如User.all,它正在工作.

在生产中,我的应用程序工作完美,没有问题,没有错误,但当我使用rails console production并输入例如User.all我有一个错误:

NameError: uninitialized constant User

在我的应用程序team/templatetags/teams_extras.py中，我有这个过滤器

from django import template

register = template.Library()

@register.filter(is_safe=True)
def quote(text):
    return "« {} »".format(text)

所以我将它用于我的视图team/templates/teams/show.html

{% extends './base.html' %}
{% load static %}
{% load teams_extras %}
...
<b>Bio :</b> {{ team.biography|quote }}
...

但这是我页面上的结果：

&laquo; <p>The Miami Heat are an American professional basketball team based in Miami. The Heat compete in the National Basketball Association as a member of the league's Eastern Conference Southeast Division</p> &raquo; 

为什么 ？谢谢

在我的 Rails 应用程序中，我将date数据库中的 a 与Time.now：

Event.date_start >= Time.now

但是Event.date_start是 ActiveSupport::TimeWithZone

一切正常，但我想知道将 aTime与 a进行比较TimeWithZone是否正确，如果不是这种情况，该怎么做？
