我按照本教程使用 Mongoid 和 Mongodb 设置了一个基本的 Rails 4 应用程序。
我在服务器上设置了乘客进行部署。当我去 domain.com:3000 应用程序工作。此外,当我访问 domain.com:28017 时,它显示 mongodb 正在运行。
在所有示例/教程中,我可以找到该应用程序托管在 localhost:3000 上,而我正在尝试部署到我的实际域。
当我转到 domain.com 时,我收到以下错误消息:
Problem:
No sessions configuration provided.
Summary:
Mongoid's configuration requires that you provide details about each session that can be connected to, and requires in the sessions config at least 1 default session to exist.
Resolution:
Double check your mongoid.yml to make sure that you have a top-level sessions key with at least 1 default session configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.
Example:
development:
sessions:
default:
database: mongoid_dev
hosts:
- localhost:27017
(Mongoid::Errors::NoSessionsConfig)
问题似乎是我的 mongoid.yml 文件,如下所示:
development:
# Configure available database sessions. (required)
sessions:
# Defines the default session. (required)
default:
# Defines the name of the default database that Mongoid can connect to.
# (required).
database: myapp_development
# Provides the hosts the default session can connect to. Must be an array
# of host:port pairs. (required)
hosts:
- localhost:27017
options:
# Change whether the session persists in safe mode by default.
# (default: false)
# safe: false
# Change the default consistency model to :eventual or :strong.
# :eventual will send reads to secondaries, :strong sends everything
# to master. (default: :eventual)
# consistency: :eventual
# How many times Moped should attempt to retry an operation after
# failure. (default: 30)
# max_retries: 30
# The time in seconds that Moped should wait before retrying an
# operation on failure. (default: 1)
# retry_interval: 1
# Configure Mongoid specific options. (optional)
options:
# Enable the identity map, needed for eager loading. (default: false)
# identity_map_enabled: false
# Includes the root model name in json serialization. (default: false)
# include_root_in_json: false
# Include the _type field in serializaion. (default: false)
# include_type_for_serialization: false
# Preload all models in development, needed when models use
# inheritance. (default: false)
# preload_models: false
# Protect id and type from mass assignment. (default: true)
# protect_sensitive_fields: true
# Raise an error when performing a #find and the document is not found.
# (default: true)
# raise_not_found_error: true
# Raise an error when defining a scope with the same name as an
# existing method. (default: false)
# scope_overwrite_exception: false
# Skip the database version check, used when connecting to a db without
# admin access. (default: false)
# skip_version_check: false
# Use Active Support's time zone in conversions. (default: true)
# use_activesupport_time_zone: true
# Ensure all times are UTC in the app side. (default: false)
# use_utc: false
test:
sessions:
default:
database: myapp_test
hosts:
- localhost:27017
options:
consistency: :strong
# In the test environment we lower the retries and retry interval to
# low amounts for fast failures.
max_retries: 1
retry_interval: 0
