Access other attributes named like reserverd words in ruby (new, end, when)
This factory won't work.
Factory.define(:announcement) do |f|
f.when { 10.hours.since..12.hours.since } # time range
f.start_time { |when| when.begin.strftime('%H:%M') }
f.end_time { |when| when.end.strftime('%H:%M') }
end
syntax error, unexpected keyword_when, expecting '|'
Hi, @cutalion thanks for the issue ❤️
I was looking into and well I have to say I think is not a limitation of the library but more of a limitation of the language.
[].each do |when|
puts when
end
Traceback (most recent call last):
syntax error, unexpected keyword_when, expecting '|'
[].each do |when|
I don't think is the good approach to try working against ruby
🙉
On another topic, I was trying to use ranges in the library and end up with a working example.
factories.define(:announcement) do |f|
f.range { ROM::SQL::Postgres::Values::Range.new(3, 9, :'[]') } # range
f.begin { |range| range.lower }
f.end { |range| range.upper }
end
announcement = factories[:announcement]
expect(announcement.begin).to eq 3
expect(announcement.end).to eq 9
I found a little verbose having to type all that code to create a range type, might be interesting to have some method to create ranges or something a little more generic for the users? WDYT? @solnic
Hi @GustavoCaso, you're of course right about language limitations. But I think that the issue is with the way of passing parameters, with API itself.
Consider the following example:
Factory.define(:announcement) do |f|
f.when { 10.hours.since..12.hours.since } # time range
f.start_time { |attrs| attrs[:when].begin.strftime('%H:%M') }
f.end_time { |attrs| attrs[:when].end.strftime('%H:%M') }
end
It wouldn't have such limitations.
Btw, I had to deal with the similar issue in dry-validation
.
validate(start_lt_end: [:when]) do |when_|
when_.begin < when_.end
end
Here at least it's possible to pick a name for a variable. In rom-factory
attribute is picked after the local variable name (nice trick).
I know this a very bad name for attribute in ruby, but it's the legacy database and it's first (two) places where it hit me. I've never had such issues in rails/activerecord/fabricator/etc
@cutalion I will see what I can do ❤️
