Find_by_sql producing different output in Rails console and Rails app

In Rails console this Active Record query:

logrow = LogForm.find_by_sql([log_row_sql(5339), 18998])[0]

... produces the output:

LogForm Load (17.0ms) SELECT masterid,activityid,firstname,surname,sex,age,address,towncity,postcode,l.county AS usercounty,tel,mobile,email,dancer,updates,source,rooms, occupancy,ch1firstname,ch1surname,ch1sex,ch1age,ch2firstname,ch2surname,ch2sex,ch2age,to_char(eventdate,'DD Mon YYYY') as eventdate,eventmusic,eventinfo,participants,vouchernum,pin,to_char(voucherexp,'DD Mon YYYY') as voucherexp,expcode,a.header as subject, a.title,a.type, a.template, p.header as dancestyle, p.text as package, l.packageid, p.package as abbrev,participants,person2_firstname,person2_surname,person2_sex,level,location,district,postarea,m.county AS provcounty,pemail,pemail2,pname,ptel,pmobile FROM log_form l, activities a, packages p, vmaster m WHERE l.id = 18998 AND l.packageid = p.id AND l.activityid = a.id AND l.masterid = m.id

.... followed by:

#<LogForm:0x007faeb396b1d0 id: nil, activityid: 9, packageid: 244, masterid: 5339, firstname: "Alan", surname: "Short", sex: "male", age: "adult", address: "12 Kember Road", towncity: "London", postcode: "SW81FG", tel: "02077629045", mobile: nil, email: "alan.short276@gmail.com", dancer: nil, updates: "yes", source: nil, eventdate: nil, eventmusic: nil, eventinfo: nil, vouchernum: "asd123", expcode: nil, voucherexp: Thu, 08 Aug 2019, rooms: nil, occupancy: nil, ch1firstname: nil, ch1surname: nil, ch1sex: nil, ch1age: nil, ch2firstname: nil, ch2surname: nil, ch2sex: nil, ch2age: nil, participants: nil, person2_firstname: nil, person2_surname: nil, person2_sex: nil, level: nil, pin: nil>

Many fields are missing in the second part of the output but in Rails console but I can access these missing attributes, eg. logrow.template ... or ... logrow[:template] and both return the data: "standard". However, the same AR query in my application returns nil for logrow[:template] despite the Rails error page showing the same value for logrow as the second part of the console output (above).

It appears these missing fields are only available within Rails console, for some reason, as the same values (5339, 18998) are passed to the same query in the app.
