params hash

Hi!

When i am submitting a form, i cannot use params. It is not a hash but HashWithIndifferentAccess. Wots this?

HashWithIndifferentAccess is simply a Rails modification to Hash to allow:

hash[‘key’] == hash[:key]

In Ruby’s native Hash, the above would be false.

What is your problem with @params?

Whne i write params[:some_symbol] after the form submission where some_symbol is some text field in the form, it shows a nil object

Hi,

Thnx for the lead.

Check the html code for the form field. the :some_symbol part must
match the "name" atribute of the form field. Parameters can be nested:

<input type="text" name="my_field" />
params[:my_field]

<input type="text" name="my_model[my_field]" />
params[:my_model][:my_field]

Cheers,
Max
