问题描述
我在执行 rake db:migrate 时遇到一个奇怪的问题
I'm having a strange problem executing rake db:migrate
== 20141127213559 CreateMovies: migrating =====================================
-- create_table(:movies)
-> 0.0033s
== 20141127213559 CreateMovies: migrated (0.0034s) ============================
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
wrong number of arguments (1 for 0)
ArgumentError: wrong number of arguments (1 for 0)
Tasks: TOP => db:migrate
(See full trace by running task with --trace)
我所做的是:
rails generate model Movie
然后编辑迁移 CreateMovies
And then edit the migration CreateMovies
class CreateMovies < ActiveRecord::Migration
def up
#drop_table :movies
create_table :movies do |t|
t.string :title
t.string :rating
t.text :description
t.datetime :release_date
# Add fields that let Rails automatically keep track
# of when movies are added or modified:
t.timestamps
end
end
def down
drop_table :movies
end
end
这是使用--trace 执行命令的输出
This is the output of executing the command with --trace
[fran@arch rottenpotatoes]$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate

任何帮助将不胜感激.谢谢.
Any help would be really appreciated. Thanks.
推荐答案
如果您使用的是 Rails 4.2.0.beta4，ActiveRecord 将需要 arel gem.将以下内容添加到您的 gem 文件中
If you are using Rails 4.2.0.beta4, ActiveRecord will require arel gem. Add the following to your gem file
gem 'arel', '6.0.0.beta2'
然后运行
bundle install
您可能会收到以下错误消息
You may get below error message
You have requested:arel = 6.0.0.beta2
The bundle currently has arel locked at 6.0.0.
Try running `bundle update arel`
然后
bundle update arel
现在您应该可以运行迁移了.
Now you should able to run migration.
