Destroy_all function with nullify

Rails
1

Hi all ,

       I am new to Ruby on Rails..
       I have a requirement to handle the has_many functionality in

helper itself. I have created the active_record object to the model
dynamically. From the object I have tried to access the has_many
functionality followed by destroy_all function.

I have posted my code and error which I received from my code . Please
help me…

Thanks in advance…

you doing this?

In any case, at least part of your problem is that the Class object
created by get_active_record doesn’t wind up with a name, which is
confusing the association code (it’s trying to generate the name of
the foreign key for the has_many). Try assigning the class to a
constant to sort that out.

As for the rest of the code, nearly any structure one could devise
would be clearer than this. If you’re using AR but not Rails, the
least you could do would be to split out the model definitions into
files and ‘require’ them in all at the top…

How can I require the models in helper. Can you give me any example with
code…?
