Question

rails select box

Asked by: terencepires

Hi there,

i'm having a hard setting up a select list in a rails form.
I want the select list to update a field called 'artist_cat' in a table called "artists" with the id value of a table called "categories", and i want the list of choices to be the value categories.name.

The box itself appears but the field 'artist_cat' is not updated...

i don't understand what's wrong with my code...

Any ideas ?

Cheers,

Terence

<p><label for="artists">Artiste ou espoir</label><br/></p>
<%= select("artist", "artist_cat", Categorie.find_all.collect {|c| [ c.cat_name, c.id ] })  %>

    What does your update action look like?

    Paste your update action for this form and the params when submitting the form and we'll check them out to see what's going on.

    Ok, here it is

      def update
    
    @artist = Artist.find(params[:id])
    if @artist.update_attributes(params[:artist])
      flash[:notice] = "L'artiste a bien été enregistré."
      #redirect_to :action => 'show', :id => @artist
      @artists = Artist.find(:all, :order => "artist_cat, name")
      render :action => "list"
    else
      flash[:notice] = 'Les modifications ont bien été enregistrées.'
      redirect_to :action => 'list'
    end
  end

    Can you send the params too?

    Check your log/development.log.
    Go to the bottom.
    Look for the update action being called.
    It'll look something like the below.

    Just the parameters line (well, all of them) is what I'd like to see.

    Processing ArtistController#update (for 127.0.0.1 at 2009-05-07 00:04:19) [PUT]
  Parameters: {"commit"=>"Update", "authenticity_token"=>"k3QXSv3j8t7VcDgH92lalDMfxmb+pKrT9o1/HUXBvxY=", "artist"=>{"name"=>"Aaron", ...}, "id"=>"833241487"}

    oh :)

    sorry :)

     

    by: wesgarrisonPosted on 2009-05-08 at 08:33:48ID: 24337083

    Okay, you ARE update the artist_cat value:
    UPDATE artists SET `bio` = '', `name_fr` = 'Alexandra Maria Lara', `name` = 'Alexandra Maria Lara', `bio_zh` = '', `artist_cat` = 0, ...

    What makes you think that you aren't updating the value?

    You should probably redirect_to :list after a successful update, too. Why re-render when you can redirect?

     

    by: terencepiresPosted on 2009-05-08 at 08:48:14ID: 24337285

    well, i see the field, but for some reason, the value passed to the update action is always the value that in current in the database and not the selected one.

    here is the generated drop down list code, which moreover is correct...

    so i assume there is something being reinitialized somewhere in the controller, am i correct ?

    <select id="artist_artist_cat" name="artist[artist_cat]"><option value="0">acteurs</option>
<option value="1">musiciens</option>
<option value="2" selected="selected">plasticiens</option></select>

    Do you have another artist_cat field there?  Maybe a hidden field or something?

    Everything looks fine to me. I don't see a re-initialization in the controller, just the update_attributes() call.

    Your option values look correct.  In fact, it looks the db is set to value 2 in the code snippet you just posted because it was set to be selected by default.
