好吧,我安装了elasticsearch-rails gem(版本0.1.5),我可以清楚地看到gem文件中的任务.
但是当我跑步的时候
bundle exec rake environment elasticsearch:import:model CLASS='Comment'
我收到这个错误.
跑步rake environment -D并没有向我展示任务.
elasticsearch正在运行,如果我卷曲http://localhost:9200它会回应我.
为什么这不起作用？
这是我的问题:
我有一个使用JavaFX + Hibernate + SQLite的桌面应用程序.这是我的模特:
@Entity
@Table(name = "usuario")
public class Usuario implements AbstractModel, Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@NotNull @Size(min=5, max=100)
private String username;
@NotNull @Size(min=5, max=100)
private String password;
@NotNull
private Boolean administrador;
@Version
private Integer version;
public Usuario() {
}
public Usuario(Integer id, String username, String password, Boolean admin, Integer version) {
this.id = id;
this.username = username;
this.password = password;
this.administrador = admin;
this.version = version;
}
@Override
public Integer getId() …我已经做了Comment.import,它返回0,这意味着在导入过程中没有错误.
我已经做了 Comment.__elasticsearch__.refresh_index!
这是我正在使用的模型:
require "datamapper_adapter"
class Comment
include DataMapper::Resource
include Elasticsearch::Model
property :id, Serial
property :email, String
property :author, String
property :description, String
property :created_at, DateTime
belongs_to :picture
validates_presence_of :email, :author, :description
settings index: { number_of_shards: 1 } do
mappings dynamic: 'false' do
indexes :id, analyzer: 'english', index_options: 'offsets'
indexes :author, analyzer: 'english', index_options: 'offsets'
indexes :description, analyzer: 'english', index_options: 'offsets'
end
end
def as_indexed_json(options={})
as_json.except("picture_id", "created_at", "email", "_persistence_state", "_repository", "_id")
end
end
而且我对elasticsearch的所有查询都返回一个空数组作为命中.
curl -XPOST 'http://localhost:9200/comments/comment/_search?pretty …private void initialize() {
loadPersistenceContext();
List<Events> events = getEventsChoiceBox(getPersistenceContext());
ObservableList<Event> data = FXCollections.observableList(events);
cbEvent.setItems(data); // Inserting data into the ChoiceBox
}
这是我的主要代码。问题是加载表单时，我将对象插入ChoiceBox中而不是属性中。
这是我的列表事件的内容
Object[]
|- String
|- Integer
Object[]
|- String
|- Integer
因此，我想要一个带有该String属性的ChoiceBox并将Integer映射到我的控制器。
我尝试了很多事情，但无法解决。
我正在尝试从seeds.rb文件中执行此行:
ActiveRecord::Base.connection.execute("UPDATE bairros SET created_at = (SELECT NOW());")
我的名为"bairros"的表有643k行,一旦rake db:seed命令到达此文件,就会抛出此错误
Mysql2::Error: Lost connection to MySQL server during query: UPDATE bairros SET created_at = (SELECT NOW());

(See full trace …我有一个简单的表格与param订单.当我的下拉列表发生变化时,我称之为:
$.post("/busca", $("#order_form").serialize(), dataType: "script")
在rails控制器端,我有一个简单format.js的处理ajax调用.事情是,这是行不通的.该js.erb模板从来没有显示.
我的日志显示Processing by BuscaController#index as */*,我不知道它*/*代表什么.有人能帮我吗？
我想做这样的事情:
@residenciais, @comerciais = TipoImovel.all.split { |t| t.residencial? }
问题是它@comerciais总是空的,因为它永远不会返回对象,因为条件是假的.
有没有更好的方法呢？
