I have the Following, however it will not show the current value when editing the record. What needs to change to correct this
<%= f.select :name, options_for_select([["Select Name", ""], "James", "John", "Richard", "Mike", "Peter"]), :class => 'small-input' %>
Thanks in Advance
Just use :
= f.select :your_field, options_for_select(array_list_of_possibilities, selected_value), :prompt => "select a name : "
Take a look at :

I have model,
class Test < ActiveRecord::Base
as_enum :test, [:test, :test_1, :test_1_2]
end
I need to create a f.select dropdown with enum. But I am facing an issue preparing dropdown with enum.
Here is my code:
<%= f.select :test, options_for_select(Test.tests.keys.to_a), {}, :class => "form-control" %>
But prepared a wrong select box.

Can anyone have any suggestion?
Use the code below. Titleize function capitalizes all the words and replaces the underscores with spaces. You can read more about it here
<%= f.select :test, Test.tests.keys.map {|test| [test.to_s.titleize, test]}, {}, :class => "form-control" %>
I'm definitely a bit of a noob, so this might be something simple that I'm overlooking, however, the searches that I've done to try and find a solution have come up empty.
I've built a form using formtastic that has 5 input fields: two are text boxes and three are select lists.
<%= semantic_form_for #player do |f| %>
<%= f.inputs do %>
<%= f.input :firstname, :label => "First Name " %>
<%= f.input :lastname, :label => "Last Name " %>
<%= f.input :leagueid, :as => :select, :collection => League.all(:order => :leaguename), :label => "League " %>
<%= f.input :team_1, :as => :select, :collection => Team.all(:order => :name), :label => "Team 1 " %>
<%= f.input :team_2, :as => :select, :collection => Team.all(:order => :name), :label => "Team 1 " %>
<% end %>
<%= f.actions %>
<% end %>
What is happening is that the Teams lists work perfectly (the team names are displayed). However, the League list is a different story. All of the entries in the list look like this (with different a different code after 'League:'):
#<League:0x007fe29c406498>
If I use the form to create a Player, it works fine. The correct league ID goes into the database and everything. I just can't figure out why the names of the teams show, while whatever-that-is shows for the league.
Any and all help is appreciated.
When converting objects to String, Ruby will convert them to the memory address like you see unless you provide a to_s method for string conversions. I haven't used formtastic, but I believe adding a to_s method to your League class should cause it to display what you want.
Try adding
def to_s
#name # use whatever you want to be displayed.
end
to the League class.
You could try explicitly specifying the fields that should be used as the text and id within the select list. I believe it would look like.
<%= f.input :leagueid, :as => :select, :collection => Hash[League.all.map { |league| [league.leaguename, league.id] }]
The syntax is crazy. The call to map is returning an array of name/id pairs, like [ ['league1', 1], ['league2', 2] ]. Calling Hash on that converts it to a hash, like {'league1' => 1, 'league2' => 2}. Seems like the select list should use this hash to populate itself.
There's an example of this at http://rdoc.info/github/justinfrench/formtastic, under the Usage section.
:member_name is the solution I think.
<%= f.input :leagueid, :as => :select, :collection => League.all(:order => :leaguename), :label => "League " %>
Will probably work for you as
<%= f.input :leagueid, :as => :select, :member_name => :league, :collection => League.all(:order => :leaguename), :label => "League " %>
My problem was I have a model with a field the same name as the model and I think that confused Formtastic
Example scaffold:
rails g scaffold Countries code:string country:string
rails g scaffold Types title:string description:string
Model:
class Sign < ActiveRecord::Base
attr_accessible :title, :country_id, :type_id
belongs_to :country
belongs_to :type
Form View:
<%= f.input :type %>
<%= f.input :country, :member_label => :country %>
Having a form without the member_label leads to the object id displaying in the select box for countries although the ID is correctly saved. The type select worked perfectly without declaring member_label.
Note that I didn't need to specify :as => :select as formtastic can deduce this from the belongs_to relationship.
Try using :
<%= form.input :league, :member_label => :leaguename %>
This will override the naming convention of the Formtastic Column Select.

Hope this helped.
I have the following:
<%= f.select :phase_names, options_for_select(["RFP Stage", "Pre Contract", "Awarded", "Unsuccessful", "Completed"]), :class => 'inputboxes' %>
It is storing it in the database, but in the edit view it does not show the stored value. How do I show it?
This:
options_for_select(your_array_list, your_selected_value)
I have a form on my Ruby on Rails3 Application with a drop menu, this is my current code for the select option:
<%= f.select :phone_type, options_for_select(["Select One", "Cell", "Work", "Office", "Home", "Other"],:disabled => ["Select One"]), :class => 'genForm_dropBox' %>
From my understanding this should have "Select One" as the default option when someone opens the page, but if they don't select one of the other options an error displays when they hit submit.
This is true in Browsers like Safari and Chrome and IE7, but in Firefox and IE8 it shows "Cell" as the first option as Select One is disabled.
I'd like it to display "Select One" by default, but have it as an unusable option when they submit the form. Do I need to script this into the controller, or model? or do I have this coded in the form wrong?
for those looking to incorporate this feature, I've taken a new approach from the model end of things. Being that all fields are required to be filled out in order for the user to submit and not receive an error alert, I gave the "Submit One" option a default value of nothing. You can take a look at the following code to see how I did that.
<%= f.select :phone_type, options_for_select([["Select One", ""], "Cell", "Work", "Office", "Home", "Other"]), :class => 'genForm_dropBox' %>
This is a little cleaner:
<%= f.select :phone_type, [ 'Cell', 'Work', 'Office', 'Home', 'Other' ], :prompt => 'Select One' %>
The :prompt argument generates an option with an empty value.
In Rails 4, this approach works well for me.
<%= f.select :status, options_for_status, prompt: 'Select One' %>
Meanwhile I have defined the options in a helper to keep the clutter out of my view.
def options_for_status
[
['First Option','first_option'],
['Second Option','second_option']
]
end
Thanks to everyone who contributed an answer.
I needed similar code for a project I'm working on and I really liked the approach Ryan Burnette took.
This is what worked for me using Rails 4.1.0.
<%= f.select :season, options_for_seasons, :prompt => 'Select One' %>
Then I defined the options in my helper.
def options_for_seasons
['Spring', 'Summer', 'Autumn', 'Winter']
end
I went with:prompt => 'Select One'because I only wanted the "Select One" option to be listed in the edit form if a season had not been previously selected.
Adding the ["Select One", ""] causes the edit screen to alway display "Select One" rather than the stored value.
Rails 3.1 (2012 Aug 17)
could be <%= f.select :phone_type, options_for_select(["Cell", "Work", "Office", "Home", "Other"]), :prompt => "Select One", :class => 'genForm_dropBox' %>
I am using Rails 3 and found that if I add
:remote => :true, there will be added to the tag the data-remote = true attribute. But I can't find a way to add custom data- attributes to the urlhelper. The followings won't work:
<%= link_to projects_path, :history => "new"%>
<%= link_to projects_path, :data-history => "new"%> #this throws an error
<%= link_to projects_path, :data_history => "new"%>
What I want to generate is:
New Project
anyone?
What about:
<%= link_to 'New Project', new_project_path, 'data-history' => 'new' %>
( http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to )
This is an elegant solution:
<%= link_to "foo", foo_path, data: { foo: "bar" } %>
