uninitialized constant NSFLessThan

[ofl]

Hello, Some NanoStore finder options(NSFLessThan, NSFBeforeDate..) doesn't seem to work.

(main)> ar = Article.find(:is_checked => {NSFGreaterThan => 0})
=> [#<Article:0x1028e740>, #<Article:0x1028b780>]

(main)> ar = Article.find(:is_checked => {NSFLessThan => 1})
=> #<NameError: uninitialized constant NSFLessThan>

(main)> ar = Article.find(:created_at => {NSFBeforeDate => Time.now})
=> #<NameError: uninitialized constant NSFBeforeDate>

Have you any suggestions ? Thanks.

If you are trying that in REPL, this could happen if you only have NSFGreaterThan in your ruby source code but not NSFLessThan or NSFBeforeDate. RubyMotion will remove all symbols not referenced by your app.

As a work around, you may include all of those symbol in your app.

Thank you for a reply.

it works. but

Article.create(created_at: Time.now)

ar = Article.find(:created_at => {NSFBeforeDate => Time.now})
=> []

or

ar = Article.find(:created_at => {NSFBeforeDate => NSDate.date})
=> []

Is it the wrong usage?

Would you please try to use NSDate for yuour created_at? The NSFBeforeDate is designed for NSDate not ruby Time.

In RubyMotion Time is not a NSDate. (this can be confirmed via REPL: Time.class.ancestors => [Class, Module, NSObject, Profiler::ObjectExt, Kernel] )

As this is not an issue of NanoStore, i'll close this issue.
