如何检索properties['text']='view'的所有事件

我尝试了Ahoy::event.where(:properties['text']=>'view').count

返回:```

Ahoy::event.where(:properties['text']=>'view')。count nomethoderror：undefined methodto_sym“for nil：nilclass from/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/activeRecord-4.2.5.1/lib/activeRecord-4.2.5.1/lib/active_record/sanitiation.rb:59:inblock in'from/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/activeRecord-4.2.5.1/lib/active_record/sanitiate.rb:58:inexpand_hash_conditions_for_aggregates'from 5.1/lib/active_record/relation/query_methods.rb:584:inwhere！‘从/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/activeRecord-4.2.5.1/lib/active_record/relation/query_methods.rb:574:inwhere“从/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/railties-4.2.5.1/lib/rails/commands/2.2.0/gems/active_record/.bundle/gems/console.rb:110:在中开始‘从/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/railties-4.2.5.1/lible/gems/ruby/2.2.5.1/lib/command/console.rb:9:在中开始’从s_tasks.rb:39:inrun_command！‘从/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/railties-4.2.5.1/lib/rails/commands.rb:17:in '从/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/active_support/dependencies.rb:274:in required code>在require“from/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/activesupport-4.2.5.1/lib/active_support/dependencies”中的块。rb:240:inload_dependency“from 2.2.0/gems/activesupport-4.2.5.1/lib/active_support/dependencies.rb:268:inload‘from/userS/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/activeSupport-4.2.5.1/lib/active_support/dependencies.rb:268:inload中的block“from/users/dariusgoore/development/blackops/.bundle/gems/ruby/2.2.0/gems/active_support/dependencies.rb:240:inload_dependencies”from code>load‘从/users/dariusgoore/.rubies/ruby-2.2.1/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:在require’从/users/dariusgoore/.rubies/ruby-2.2.1/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:在require'```

我曾在网上查询哈希属性，但没有成功。任何指导都是非常感谢的。




Answer 1

Ahoy：：事件实际上不会返回任何有用的东西。要获取数组返回对象中的所有记录，需要使用Ahoy::event.all。

所以你实际上需要做的是以下几点：

Ahoy::event.all.select{event event.properties['text']==“view”}.size
