This error can happen on endless loop or never ending recursive  
function,  
CAn u show app/models/mymailertest.rb content and method on app/  
controllers/account\_controller.rb:261 ?

It’s also common to see this when accessor methods are misused. Suppose  
the following:

class Test  
def initialize(new\_value = “Foo”)  
@my\_value = new\_value  
end

def my\_value  
@my\_value  
end

def my\_value=(new\_value)  
self.my\_value = new\_value  
end  
end

test = Test.new  
test.my\_value = “Bar”  
puts test.my\_value

In this contrived example notice how the setter method is calling itself  
in an attempt to set my\_value. Hence an infinite loop in the setter and  
a “stack level too deep” is the side-effect.

Of course the proper syntax for the setter should be:

def my\_value=(new\_value)  
@my\_value = new\_value  
end

Maybe your case if different, but I’ve seen this happen so I thought I’d  
mention it before you spend too much time on something silly like this.

Hi alexey,

```
Thanks for your reply.This is my

```

app/controllers/account\_controller.rb:261?

```
Mymailertest.deliver_welcome(recipient,subject,message)

```

app/models/mymailertest.rb

def welcome(recipient, subject, message, sent\_at = Time.now)  
@subject = subject  
@recipients = recipient  
@from = ‘’  
@sent\_on = sent\_at  
@body[“title”] = ‘This is title’  
@body[“email”] = ‘’  
@body[“message”] = message  
@headers = {}  
end

calling and called function.
