access to record params with ActiveRecord relation number

I'm trying to get a record in DB by having these two lines in one of my models:

a = Arel::Table.new(:receivers)
e = Receiver.where(a[:name].matches('%afsane%'))

In my receivers table I have a row in which the name column equals to "afsane".I want to have that row's id in my model. but by printing the e in my model I've got this :

"========#<Receiver::ActiveRecord_Relation:0x0056094261eff8>============"

which gives the relation number but no params. When I run them in rails console I got this response:

 #<ActiveRecord::Relation [#<Receiver id: 2, name: "afsane", created_at: "2016-09-27 09:24:16", updated_at: "2016-10-09 10:10:02">]>

I managed to have this in my model But I couldn't .

ps:Using Rails 5.

Have any Ideas ?

I'm not sure what the variable a looks like but the variable e is a collection. where returns a collection which means you will have to iterate through e in order to pull out some data.

Like so:

e.each do |data|
  data.name
end

If you want to return only 1 result then you can simply do the following:

e = Receiver.where(a[:name].matches('%afsane%')).limit(1)

Note: I've kept the answer simple but there are more elegant solutions to this so I recommend you reading the ActiveRecord Rails Guides
