Hi all

I’m moving to using Machinist in my rspec tests and am having a problem  
with an after\_create callback method that i need to stub out. It seems  
like calling ClassName.make will trigger this callback before i’ve had  
the chance to stub it.

Can i stub it in my blueprint for that class? Or, can i stub the method  
for all instances of the class before i call ClassName.make?

Hey Max,

Try:

instance = YourModel.make\_unsaved

then stub the after\_create method and save the object.

installed i could have found that myself.
