Question

I am new to ruby on rails. I have passed parameters ISDCode,AreaCode and Telephone number using POST from a form.

I have a string with information of the format countryName(ISDCode) passed in the variable ISDCode. For example “United States of America(+1)”.

Now I want to save only the value of the ISDCode in the database.

What would be the ideal way to extract the ISD Code from the string?

Should I extract the ISD Code in Javascript before user POSTs the form or should I extract it in the model using a callback ?

Also is regex the only way to extract the information?

Answer 1

Since the string is from auto completion, the ISDcodes should be existing in your database. So the best solution may be including an extra parameter (with a hidden input), like isdcode_id, then you simply use isdcode_id in your model. This way you can avoid the trouble to parse the string.

If this is not feasible, regex could be the best way to extract the information. You can override the setter in the model to do it.
