[英]Error undefined method `to_key' for [xxx] :Array when trying to use array data on Active Admin table_for (Rails, Postgresql, postgres_ext gem)
I'd like to have use the data I manage to get inside an array of array to put them inside a table(table_for) on one of my Dashboards on Active Admin 我想使用我设法获取的数据放入一个数组数组中,以将它们放在Active Admin上一个仪表板上的表(table_for)中
My app is a Daily Deal app built to learn more Ruby on Rails. 我的应用程序是Daily Deal应用程序,旨在了解更多Ruby on Rails。
Thanks to help on SO, I now manage to get all the data i need inside an Array: Count occurrence of values in a serialized attribute(array) in Active Admin dashboard (Rails, Active admin 1.0, Postgresql database, postgres_ext gem) 多亏了SO方面的帮助,我现在设法在阵列中获取所需的所有数据: 在Active Admin仪表板(Rails,Active admin 1.0,Postgresql数据库,postgres_ext gem)中对序列化属性(数组)中值的出现进行计数
The array's data I want to use looks like (it's actually an array of array) 我要使用的数组数据看起来像(实际上是数组的数组)
But what i'd like is something looking like the image below, so i want to use Active Admin's table_for (to have all the export features later on): 但是我想要的东西看起来像下面的图片,所以我想使用Active Admin的table_for(稍后再使用所有导出功能):
My current code on my Dashboard page is 我在“信息中心”页面上的当前代码是
columns do
column do
data = Deal.connection.select_rows(
%q{ with expanded_deals(id, goal) as (
select id, unnest(deal_main_goal)
from deals)
select goal, count(*) n
from expanded_deals
group by goal
order by goal; }).each do |row|
goal = row.first
n = row.last.to_i
#....
end
panel "Top Goals" do
table_for data do
#code
end
end
end
end
Even without putting any code inside table_for data, I already get the error: 即使没有在table_for数据中放入任何代码,我也已经收到错误:
undefined method `to_key' for ["Acquisition (website or newsletter opt-ins)", "3"]:Array
How can I use the array's data to put them inside a standard table_for with my basic columns "goal"/"number of deals"? 如何使用数组的数据将其放入标准table_for中,并将其基本列设为“目标” /“交易数量”?
I might have stumbled upon a ticket on AA that says it might not be possible: https://github.com/gregbell/active_admin/issues/1713 我可能偶然发现了AA上的罚单,说这不可能: https : //github.com/gregbell/active_admin/issues/1713
Would anybody know how to do that? 有人知道该怎么做吗?
I just opened a pull request to add this functionality: https://github.com/gregbell/active_admin/pull/2812 我刚刚打开请求请求以添加此功能: https : //github.com/gregbell/active_admin/pull/2812
Which lets you use arbitrary data in a table, like this: 它使您可以在表中使用任意数据,如下所示:
table_for foo: 1, bar: 2 do
column :foo
column :bar
end
Please give the pull request a try by putting this in your Gemfile: 请通过将其放入您的Gemfile中来尝试拉取请求:

branch: 'feature/1713-support_arbitrary_objects_for_tables'
This has now been merged into master: 现在,它已合并到master:
