在捆绑安装gem(gem'rolify')之后,我使用以下命令生成了该文件,
rails g rolify Role User
下面的文件已创建,
invoke active_record
create app/models/role.rb
invoke rspec
create spec/models/role_spec.rb
invoke factory_girl
create spec/factories/roles.rb
insert app/models/role.rb
create db/migrate/20140425070708_rolify_create_roles
insert app/models/user.rb
create config/initializers/rolify.rb
然后,我给了
rake db:migrate
它给了我警告,
[WARN] table 'Role' doesn't exist. Did you run the migration ? Ignoring rolify config.
表也没有创建.我在这里错过了什么问题.这是我的迁移文件,
class RolifyCreateRoles < ActiveRecord::Migration
def change
create_table(:roles) do |t|
t.string :name
t.references :resource, :polymorphic => true
t.timestamps
end
create_table(:users_roles, :id => false) do |t|
t.references :user
t.references :role
end
add_index(:roles, :name)
add_index(:roles, [ :name, …我的网页
<ul class="nav nav-tabs tabs-up" id="friends">
<li><a href="http://localhost:3000/contacts" data-target="#contacts" class="media_node active span" id="contacts_tab" data-toggle="tabajax" rel="tooltip"> Contacts </a></li>
<li><a href="http://localhost:3000/follows/friends_list" data-target="#friends_list" class="media_node span" id="friends_list_tab" data-toggle="tabajax" rel="tooltip"> Friends list</a></li>

</ul>
<div class="tab-pane active" id="contacts">
</div>
<div class="tab-pane" id="friends_list">
</div>
<div class="tab-pane urlbox span8" id="awaiting_request">
</div>
我的 JavaScript 代码：
$('[data-toggle="tabajax"]').click(function (e)
{
e.preventDefault()
var loadurl = $(this).attr('href')
var targ = $(this).attr('data-target')
$.get(loadurl, function(data) {
$(targ).html(data)
});
$(this).tab('show')
return false;
});
我分别给出了选项卡的链接。但是当单击选项卡时我无法在页面中呈现这些链接。任何人都可以帮助我解决这个问题。

目前在我的tmuxinator yml文件中有此文件，
windows:
- editor:
layout: main-horizontal
panes:
- vim
-
- server: rails s
这给了我2个窗口，一个用于编辑器，另一个用于服务器。在编辑器窗口中，我有两个窗格，一个用于vim，另一个是空白窗格，我可以在其中使用一些命令。但我想将该空白窗格进一步分为两个垂直窗格，即
windows:
- editor:
layout: main-horizontal
panes:
- vim
- (I want to split this pane into two vertical pane, in which i can run my rails console in one pane and i can use the other for executing commands)
- server: rails s
因此，总计我的第一个窗口中将有3个窗格。有人可以帮我吗。
谢谢。
我向rails发了一个ajax请求.URL是:
/learners/-638284588?is_combined_page=true&email=test0221k+staging@tt.com&type=ld"
在日志中,我看到这些条目:
Started GET "/learners/-638284588?is_combined_page=true& email=test0221k+staging@rosettastone.com&type=lcd" for 127.0.0.1 at Fri Feb 23 09:31:56 -0500 2018
Processing by Extranet::LearnersController#show as HTML
Parameters: {"type"=>"ld", "email"=>"test0221k staging@tt.com", "is_combined_page"=>"true", "id"=>"-638284588"}
[WARNING] Audit logging has been enabled for Account
parameter ----------------> {"type"=>"lcd", "email"=>"test0221k staging@tt.com", "controller"=>"extranet/learners", "is_combined_page"=>"true", "action"=>"show", "id"=>"-638284588"} test0221k staging@tt.com
在URL中,email参数显示为:
email="test0221k+staging@tt.com"
有一个+标志.但是当我从中读取参数时params[:email],它被打印为:
"email"=>"test0221k staging@tt.com"
其中+由空格代替.
为什么rails会+用空格覆盖？我该如何避免这种情况"test0221k staging@tt.com"并获得"test0221k+staging@tt.com"？
