Hi,

I need to set up an initial value from controller. In my views I’ve  
something like  
\<%= text\_field “object”, “name” %\>

and would like to do something like this from controller

def index  
@object[:name] = ‘default value’  
end

but still got an error. Object doesn’t have database model (and will not  
have)

Thank you

## PS: now using \<%= text\_field\_tag “object\_name”, @object\_value %\> and setting in as @object\_value = ‘something’, but is not so elegant…

Have you tried?

def index  
@object = Object.new  
@object.name = ‘default value’  
…  
end

Sure, but got error:

undefined method `name=’ for #Object:0x333c1a0

with  
def index  
@sometest = Object.new  
@sometest.name = ‘testname’  
end

</div>

and you’ve done attr\_accessor :name or some equivalent in the class  
definition?
