current i am trying to restrict the information feed into an option select field to only display the criteria i have selected. with the code below this seems to be working
= select("schedule", :selected_players, User.where(:team_id => current_user[:team_id]) { |p| [full_name(p), p.id] }, {:include_blank => 'None', :prompt => 'Add Players to Lineup'}, :multiple => "multiple")
the issue is that this code is display an array field type i.e #<User:0xa559830>
how do i get it to display the actual users name?
Define .to_s method in model
Like here
https://github.com/roolo/mwstt/blob/master/app/models/project.rb#L7
Also all the mapping and searching logic should be placed in model as method which you'll just call in view, or prepare it in controller!

I currently have a multiple select box in a rails form that looks like this:
= select_tag :in_all_tags, options_from_collection_for_select(Tag.where(:project_id => #project.id), :id, :name, #in_all_tags_param), { :id => "tags", :tabindex => "3", "data-placeholder" => "Choose Tags", :multiple => "multiple" }
Where
#in_all_tags_param = params[:in_all_tags]
The problem is, #in_all_tags_param will only populate the select form with the last value from params[:in_all_tags]. So, if the url string reads in_all_tags=5&in_all_tags=8, the pre-selected value in the multiple select will only be 8.
From what I understand, the way around this is to append [] to the field name for multiple params, so that :in_all_tags becomes in_all_tags[]
BUT, when I try this, submitting the form returns:
Expected type :default in params[:in_all_tags], got Array
Any suggestions appreciated.
Cheers...
You need to add a :name element to the same hash with :multiple => true in it. So I use something similar for Genres on an app for mine and I do { :multiple => true, :name => "lesson[genre_ids][]" }. The name has to be model[attribute][].
i am currently using this select = select(:schedule, :selected_players, #players.map { |p| [full_name(p), p.id] }, {:include_blank => 'None'}, "data-placeholder" => 'Add Players to Lineup', :prompt => 'Add Players to Lineup', :multiple => "multiple")
and would like to store the information into an array within the database, then access this array for different pars of the site
there is a copy of things im needing to know
how best to store into the database, current this field value is binary
how to then extract each value from the array
thanks
Sounds like you want serialize.
If you make the selected_players column a text column and mark your Schedule model with
serialize :selected_players
Then you can save a Ruby array into the attribute. It'll be written to the database in YAML, and pop out exactly as it went in, as an array, when you read it.
Currently I am trying to restrict the information feed into an option select field to only display the criteria I have selected. With the code below this seems to be working
= select("schedule", :selected_players, User.where(:team_id => current_user[:team_id]) { |p| [full_name(p), p.id] }, {:include_blank => 'None', :prompt => 'Add Players to Lineup'}, :multiple => "multiple")
The issue is that this code is displaying an array field type i.e #<User:0xa559830>.
How do I get it to display the actual users name?
I suggest rewriting the code with greater separation and clarity instead of trying to fit it all in one line. Model methods that generate SQL should never be called from views.
In the controller:
#players = User.where(:team_id => current_user[:team_id]).all
In the view:
= select :schedule, :selected_players, #players.map {|p| [full_name(p), p.id] }, {:include_blank => true}...
I think the original error in your code appears to be that you were calling a block after the where method without an iterator (each).
I'm using an out-dated version of rails (2.2).
I have a page which has a search filter. When I filter the options, I would like the Dropdown boxes to default to the filters I selected. The filters are being stored as parameters in the URL. i.e. filter[Issue+Header]=test&filter[in4User]=1&filter[Module]=3
What I search:

What I currently see when page loads (as you can see, text boxes are re-populated, but dropdowns are not):

Example of a collection_select I am using:
<%= collection_select(:filter, "Client", Client.find(:all, :conditions => ['status = 0']), :ClientID, :Name, :include_blank => true) %>
What you need to do is pass in the :selected option into collection select, and pass the appropriate param as the value, so something like:
<%= collection_select(:filter, "Client", Client.find(:all, :conditions => ['status = 0']), :ClientID, :Name, :include_blank => true, :selected => params[:filter]) %>
That should select the client, assuming that the Client is in the collection.
I have a partial that renders a select box using the following method:
<%= collection_select 'type', 'id', #types, "id", "name",
{:prompt => true},
{:onchange =>
remote_function(
:loading => "Form.Element.disable('go_button')",
:url => '/sfc/criteria/services',
:with => "'type_id=' + encodeURIComponent(value) + '&use_wizard=#{use_wizard}'"),
:class => "hosp_select_buttons"
} %>
This partial gets used 2 times on every page, but at one point I need to get the value of the first select box. Using:
$('type_id')
returns the second select box. Is there a way to find the first one easily? Should I fix this using javascript or by redoing my partial?
Note: the dropdowns do get rendered in separate forms.
Yes, each element does need a unique ID, the page probably also fails HTML validation. Also, unless these are in 2 different forms you'll have a conflict with the CGI parameter name.
If they are in 2 different forms you can probably get away with just setting the :id as you posted, if they are the same form you need to abstract the parameter name too:
collection_select 'type', "id_wizard_#{use_wizard}"...
I figured out one way to do this by assigning an ID in the html_options block. I already am passing in a value for use_wizard, so I can append that value on to the ID to differentiate between the two dropdowns.
:id => "type_id_wizard_#{use_wizard}"
