If you check this out - it's in my factories.rb file: ------ # Factories Factory.define :article do |t| t.association :section # 'belongs to a section' t.title {|x| "#{x.section.name}Article" + Factory.next(:count) } ... end
(...)
Factory.define :page do |t| t.title "Page#{Factory.next(:count)}"
Why are you using the same sequence in two different factories?
t.styles "styles here" t.body Forgery::LoremIpsum.paragraphs(5) end
# Sequences Factory.sequence :count do |n| n end
OK. Got it. Now what's the question?
Best,
Why are you using the same sequence in two different factories?
I just want a way to number things differently for multiple factories. I originally had a sequence called :article_title, but then I didn't want to make something SO similar later with :page_title, and I all I really need is number that increments...
OK. Got it. Now what's the question?
I get an error in the factory for :page, but not an error for :article, regarding the sequence :count.
This suggests that I can't call "Factory.next(:count)" in different factories.
Is this the case? Or is there something wrong with my methodology?

Do you have your :count sequence defined in factories/factories.rb? I have a similar case defined in this file and it works fine:
I have everything above defined in one file: test/factories.rb. Is that a problem? The doc (https://github.com/thoughtbot/factory_girl/wiki/Usage) says it's okay to put your factory-related code here...

You are fine… I had a problem and did not know to put my code there.
What?? If I'm fine, then why isn't the :count sequence working for one of the factories? (read first post)
Figured it out. Here's the summary:
If you have a sequence called :xyz and you are calling it in a factory, YOU NEED TO HAVE BRACKETS around the Factory.next(:xyz) call. In my case:
# Factories Factory.define :article do |t| t.association :section # 'belongs to a section' t.title {|x| "Article#{Factory.next(:count)}" } (...) end (...) Factory.define :page do |t| t.title { "Page#{Factory.next(:count)}" } # I originally didn't have brackets here; that's why it didn't work, while it did work above! (...) end # Sequences Factory.sequence :count do |n| n end
Hope this helps people who come across the same issue.
As a note, in the case where you just want a number in a string I prefer this syntax:
Factory.define :article do |t| t.association :section t.sequence(:title) {|n| "Article#{n}"} end
That way you don't have a sequence who's only job is to replicate this functionality; save those sequences for something that is more complex that you want to reuse and count.

Oh! Thank you!
Wait.... what if you wanted to do this?
t.title {|x| "#{x.section.name}Article#{Factory.next(:count)}" }
So would this be a scenario in which it's better to have a separate sequence for "something that is more complex" - so like a sequence called :article_title?
The tricky part there is that you want both the sequence and the handle to the object that you're creating. I think that means you can't use the shortcut syntax I had (or at least I don't see how), but it also means you can't use a Factory.sequence :foobar do ... end, because that won't know your x object and it doesn't look like you can pass in a context like you can with the other Factory objects.
It seems like you have three options which are: 1) Do something like what you're doing, although if you need to share part of it you could make a sequence :article_title for "article_#{n}" and then do
t.title {|x| "#{x.section.name}_#{Factory.next(:article_title)}"}
2) You could not put the x.section.name in the title; that'd be my first inclination as it'd seem odd if the name you have is required to be that, since its just for testing purposes.
3) You could patch factory_girl's sequence to take a context like the object factories. Look at https://github.com/thoughtbot/factory_girl/blob/master/lib/factory_girl/sequence.rb; basically you want to override the next method to take options and pass them into the call in there. I'm not sure exactly how the object part does it, but in theory one should be able to look at that and emulate the appropriate stuff.
Wow, that's great - thanks for the thorough response. I guess I'll use the
t.sequence(:title) {|n| "Article#{n}"}
style when I can, but otherwise I'll have to keep that :count....
Thanks again!
