forms - Is there a way to set a distinct ID and name for a text_field in Rails 2? -

i've got rails 2 site i'm trying add form handler to, i'm running problems converting html form fields form handler fields.

the form code begins with:

    <% form_for @newsavedmap, :html=>{:id=>'createamap'} |f| %> 

i keep getting errors when try things

    <%= text_field :newsavedmap, :html=>{ :value => 'new map', :name=>'newsavedmapname', :id=> 'savedmap_name', :size => '30' } %> 

error:

    actionview::templateerror (wrong number of arguments (1 2)) on line #284 of app/views/layouts/maptry.html.erb: 

here fields. how can convert these form handler fields in rails 2?

    <input id="savemap_name" name="newsavedmapname" size="30" type="text" value="new map"></p>      <select id="startdrop" name="startthere">     <options here>     </select>      <select multiple id="waypoints" class="mobile-waypoints-remove" name="waypointsselected[]">     <options here>     </select> 

thanks can provide!

edit 1 error code text_field

using bigxiang's approach, get

    processing newsavedmapscontroller#create (for ip @ date time) [post]     parameters: {"endhere"=>"", "endthere"=>"sample address 1", "newsavedmap"=>{"newsavedmapname"=>"test map"}, "startthere"=>"sample address 2", "starthere"=>"", "optimize"=>"on"}      activerecord::unknownattributeerror (unknown attribute: newsavedmapname) 

the line "newsavedmap"=>{"newsavedmapname"=>"test map"} should read

    "newsavedmapname"=>"test map" 

how can this? controller starts with:

    def create      @newsavedmap = newsavedmap.new(params[:newsavedmap])     @newsavedmap.name = params[:newsavedmapname] 

try this:

<% form_for @newsavedmap, :html=>{:id=>'createamap'} |f| %>   <%= f.text_field :newsavedmapname :id=>"savemap_name", :size=>30, :value=>"new map"%>   <%= f.select :startthere, your_collections, {}, {:id=>"startdrop"}%>   <%= f.select :waypointsselected, your_collections, {}, {:id=>"waypoints", :class=>"mobile-waypoints-remove", :multiple => true}%> <% end %> 

make sure your_collections should array ['a', 'b', 'c'] or [['name1', id1],['name2', id2],['name3', id3]].

if persist parameter "newsavedmapname"=>"test map", try this:

<% form_for @newsavedmap, :html=>{:id=>'createamap'} |f| %>   <%= text_field_tag :newsavedmapname, "new map", :id=>"savemap_name", :size=>30%>   <%= select_tag :startthere, options_for_select(your_collections), {:id=>"startdrop"}%>   <%= select_tag :waypointsselected, options_for_select(your_collections), {:id=>"waypoints", :class=>"mobile-waypoints-remove", :multiple => true}%> <% end %> 

but don't understand why not use parameter's name same column's name. example, see newsavedmap model has column named "name". can use directly

<% form_for @newsavedmap, :html=>{:id=>'createamap'} |f| %>   <%= f.text_field :name , :value=>"new map" %> <% end %> 

in controller , can delete line @newsavedmap.name = params[:newsavedmapname]

def create    @newsavedmap = newsavedmap.new(params[:newsavedmap])    if @newsavedmap.save     #######   end end
