keep values after submit

I know how I can keep my form where I ha开发者_开发问答ve a select list is not deleted after a submit?

This is the line I use to fill the select list:

<% = select: search,: style, [[All, ""]] + Proyect.all (: group => "style",: order => "style"). collect {| a | [a. style a.estilo]}%>

please help me

Thanks in advance

yeah. was very simple.

Solved with the folowing parameters added to the current line:

{:selected=>params[:search][:style]}

thus leaving

<% = select: search,: style, [[All, ""]] + Proyect.all (: group => "style",: order => "style"). collect {| a | [a. style a.estilo]},{:selected=>params[:search][:style]}%>

thanks anyway

That's right, but my solution, half good solution, because I have the problem that if the parameter still not been created?

How to do something like this:

{: selected => params [: search] [: style] if params [: search] [: style]! = nil}%>

being as follows:

<% = select: search,: style, [[All, ""]] + Proyect.all (: group => "style",: order => "style"). collect {| a | [a. ]},{: a.estilo style selected => params [: search] [: style] if params [: search] [: style]! = nil}%>

any ideas?

You need to set what option is selected. This case the 2nd one is selected:

<%=  options_for_select([['Lisbon', 1], ['Madrid', 2], ...], 2) %>
