Recover select value

I have in my view a select

<%= select :nomdefaut, @mydefaut,
@ndefaut%>

I see the different values of @ndefaut but then but then @mydefaut is
supposed to contain the selected value in the list but when I display
@mydefaut in the view my text field is blank.

I see that we can use collection_tag too but they never show how to
recover the selected value.

Somebody can help me?

have you tried accessing through params[:nomdefaut]

I’m not sure those parameters do what you think they do - What the above
does is create a select tag, where the preselected value is given by
@nomdefaut.send(@mydefaut).

Where is this textfield that is supposed to display this value?
Typically
the select is part of a form, once submitted it’s up to the receiving
action to use what is in the submitted parameters hash as it sees fit
