我有一个名为"users"的模型,我创建了一个新的迁移,将一些列添加到users表中.现在当我运行rake db:migrate时,我得到下面的错误b/c它试图再次创建users表
$ rake db:migrate
== DeviseCreateUsers: migrating ==============================================
-- create_table(:users)
rake aborted!
An error has occurred, all later migrations canceled:
Mysql::Error: Table 'users' already exists: CREATE TABLE `users`.....
为什么要再次创建表？
这是我用来创建新迁移的命令
$ rails generate migration AddDetailsToUsers home_phone:decimal cell_phone:decimal work_phone:decimal birthday:date home_address:text work_address:text position:string company:string
新迁移如下所示:
class AddDetailsToUsers < ActiveRecord::Migration
def change
add_column :users, :home_phone, :decimal
add_column :users, :cell_phone, :decimal
add_column :users, :work_phone, :decimal
add_column :users, :birthday, :date
add_column :users, :home_address, :text
add_column :users, :work_address, :text
add_column :users, :position, :string
add_column …我在React-Redux应用程序上创建了2条路线.我已经添加了主页和回调URL的github应用程序设置.
1.当您点击此路线时:https://reduxapp.herokuapp.com/signin 您点击Github登录按钮,==> githubGeturi
2. Github使用代码https://reduxapp.herokuapp.com/auth/callback?code=9536286a59228e7784a1重定向, 并触发githubSendCode('9536286a59228e7784a1')操作
您可以在网络呼叫中看到OPTIONS呼叫通过,但POST呼叫永远不会发生.并且您收到控制台错误:
XMLHttpRequest cannot load https://github.com/login/oauth/access_token?client_id=32b70bf671e04762b26c&…_secret=123456789123456789123456789&code=9536286a59228e7784a1. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://reduxapp.herokuapp.com' is therefore not allowed access.
以下是我的行动功能:

EOFError (end of file reached):
我之前遇到过这个问题,这是由于我使用zoho邮件的smtp设置.
我相信我的配置是解决问题的原因:
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => "smtp.zoho.com",
:port => 465,
:domain => 'example.com',
:user_name => 'user@example.com',
:password => 'password',
:authentication => :login,
:ssl => true,
:tls => true,
:enable_starttls_auto => true
}
现在我们已经向网站添加了SSL,我相信这就是导致此错误发生的原因.
有没有人对SSL的错误或zoho邮件smtp设置有任何了解？
我有一个对话框,其中不包含页面加载的内容,我根据用户点击的链接动态设置对话框的内容.
<p:dialog widgetVar="dlg" modal="true" id="dialog">
<p:panel id="fullArticle">
<h:outputText value="#{content.newsArticle}" escape="false" />
</p:panel>
</p:dialog>
...
...
<p:commandLink value="Read more" actionListener="#{content.getFullArticle}" onclick='dlg.show();' update=":fullArticle">
<f:attribute name="contentId" value="#{news.contentId}" />
</p:commandLink>
我遇到的问题是,当您单击"阅读更多"链接时,它会显示对话框,但对话框不在页面的中心.如果我将commandLink上的udpate属性更改为update=":dialog",则对话框会闪烁,就好像它正在打开然后立即关闭一样.
如何更新对话框并使其以动态内容为中心？
鉴于下面的代码,是否可以p使用Java中的这种for循环样式从属性列表中删除索引？
List<Properties> propertiesList = new ArrayList<Properties>();
String keyToDelete = "blah";
for(Properties p : propertiesList) {
if(p.getKey().equals(keyToDelete)) {
propertiesList.remove(index) //How to remove the element at index 'p'
}
}
这就是我用另一个for循环完成这个的方法
List<Properties> propertiesList = new ArrayList<Properties>();
String keyToDelete = "blah";
for(int i = 0; i < propertiesList.size(); i++) {
if(p.getKey().equals(keyToDelete)) {
propertiesList.remove(i);
}
}
这似乎是一个非常简单的问题,但我无法弄清楚.
我只是试图断言一个字符串等于"string1"或"string2".
这是我尝试过的,但显然都不起作用.
assertEquals(d.getFormType(), "string1") || assertEquals(d.getFormType(), "string2");
assertEquals(d.getFormType(), "string1" || "string2");
我有一个Google Apps帐户.我正在尝试使用服务帐户代表用户发送电子邮件.
我已经浏览了互联网,没有任何工作,我几乎不知所措.
我跟着Java指南,我仍然继续 com.google.api.client.auth.oauth2.TokenResponseException: 401 Unauthorized
为什么这段代码片段给我401 Unauthorized？

这些方法基本上是从Googles文档中复制/粘贴的:

我可以使用.p12密钥文件使用域服务授权的Google服务帐户.
我想使用JSON密钥文件而不是p12文件,但我无法弄清楚如何在使用JSON密钥时设置服务帐户ID.
如何使用JSON密钥文件将用户设置为模拟？
工作良好:
File p12File = new File(...);
GoogleCredential.Builder b = new GoogleCredential.Builder().setTransport(HTTP_TRANSPORT)
.setJsonFactory(JSON_FACTORY).setServiceAccountId(properties.getServiceAccountId())
.setServiceAccountPrivateKey(SecurityUtils.loadPrivateKeyFromKeyStore(SecurityUtils.getPkcs12KeyStore(),
new FileInputStream(p12File), "notasecret",
"privatekey", "notasecret"))
.setServiceAccountScopes(GOOGLE_SCOPE_LIST);
if (properties.getServiceAccountEmail() != null) {
b = b.setServiceAccountUser(properties.getServiceAccountEmail());
}
credential = b.build();
不起作用:
