I have a form that updates an #identity object. Two #identity attributes need to be assigned from a separate collection #accounts.
#accounts = [{
'name' => 'A',
'page_id' => 1},
{
'name' => 'B',
'page_id' => 2
}]
The form needs display the name, but pass both the name and page_id.
<%= simple_form_for(#identity, :remote => true) do |f| %>
<%= f.input :page_name, :collection => #accounts.map { |a| a['name'] }, :as => :radio_buttons, :item_wrapper_tag => :li %>
<%= f.submit 'Submit', :class => 'btn btn-primary' %>
<% end %>
How can I also pass the matching page_id attribute without displaying it?
:collection => #accounts.map { |e| [e['name'], e['page_id']] }

How would one do something like:
= f.input_field :age,
:collection => 18..60,
:id => 'age',
:selected => params[:age].blank? or "20"
Above doesen't work. I want to be able to set a default value if there is no param available for that attribute.
Any smart way to do this thx!
EDIT 1:
Full form:
= simple_form_for :people, :url => request.fullpath, :method => :get, :html => { :class => 'form-search' } do |f|
#container_search_small.form-search
= f.input_field :age,
:collection => 18..60,
:id => 'age',
:selected => params[:people][:age_from] || "20"
= f.submit "Go »"
You're using helpers that are taking their values from the object you're building the form on.
So in your controller, you should preset the values on the object.
def some_action
#people = People.new
#people.age = params[:age] || 20
end
Then in the form, remove the :selected option and it should be fine. Make sure you build the form for #people :
= simple_form_for #people, :url => request.fullpath, :method => :get, :html => { :class => 'form-search' } do |f|
#container_search_small.form-search
= f.input_field :age,
:collection => 18..60,
:id => 'age'
= f.submit "Go »"
I have this simple_form
<%= simple_form_for(#order) do |f| %>
<%= f.error_notification %>
<%= f.association :orderstatus, :label => false, :include_blank => false, :input_html => { :class => 'order-status' } , :as => :radio, :label_html => { :style => "background-color:black;" } %>
<%= f.button :submit, :value => 'Update', :class => 'button grey small' %>
<% end %>
And it creates this: http://d.pr/9Bqd In the database I also have a field color which is a hex code for the background color I want of each status. Any idea how to pass this hex code onto each background label color?! I've tried for hours.
Have you tried passing it in like this...
# assuming "hex" is stored in the order model. Any variable should work
:label_html => { :style => "background-color:##{#order.hex};" }
If not, please respond with your results
Here is my view:
<%= form_tag({ :action => "display"}, :method => "get") do %>
<%= select(:music, :type, MusType::TYPES, {:include_blank => true}) %>
Here is my array constant in the model:
class MusType < ActiveRecord::Base
TYPES = ['Jazz','Rock','Blues']
end
My select menu draws values out of an array. How do I pass the selected value into the controller as a parameter after the submit button is pressed?
you can do something like below.
view code
<%= form_tag(:url => {:controller => "mycontroller" :action => "display"}, :method => "get") do %>
<%= select_tag(:music, :type, MusType::TYPES, {:include_blank => true}) %>
<%= submit_tag "Search", :id => 'search' %>
<% end %>
read the selected value in mycontroller.rb
def display
value = params[:music][:type]
// do something with value
end
Excuse me, I am a newbie programmer in Rails.
I want use AJAX in a DATE SELECT. when I change the date, change the punitive ammount depends the result of method get_punitive (Model).
I use the next code in Controller, Model and View.However the event On change is not recognized. please you could help me.
Operations Model (partially)
def get_punitive(payment_date, expiration_date)
if payment_date > expiration_date
expiration_days= (payment_date - expiration_date).to_i
else
expiration_days = 0
end
punitive_ammount = (self.capital * (self.interest_rate_for_taker / 100.0) * expiration_days) / 30
# raise punitive_ammount.inspect
end
Operations Controller (partially)
def cancel
#operation = Operation.find(params[:id])
last_pagare = Pagare.find(:first, :conditions => "operation_id = #{#operation.id} AND state <> 'cancelled'")
#punitive_ammount = #operation.get_punitive(DateTime.now.to_date, last_pagare.expiration_date.to_date)
end
def update_payment_date
raise params.inspect
end
def submit_cancellation
#operation = Operation.find(params[:id])
ammount = params[:ammount]
punitive_ammount = (params[:punitive_ammount].blank?) ? 0 : params[:punitive_ammount]
payment_date = Date.new(params[:"payment_date(1i)"], params(:"payment_date(2i)"), params(:"payment_date(3i)"))
admin = User.find_by_login('admin')
if #operation.cancel(ammount, punitive_ammount, admin, payment_date)
respond_to do |format|
format.html { redirect_to(admin_operations_url) }
format.xml { head :ok }
end
else
#operation.errors.add_to_base("Los montos ingresados son invalidos")
render :action => 'cancel'
end
View of cancel
Cancelacion de Operaciones
<% form_for(#operation, :url => submit_cancellation_admin_operation_path) do |f| %>
<%= f.error_messages %>
<%= text_field_tag :a, :onClick => "javascript:alert('hola');" %>
<p>Fecha de Pago:<br/><br/>
<%= date_select("", :payment_date, {:start_date => Time.now, :onchange => remote_function(:url => {:controller => 'operations', :action => "update_payment_date"}, :with => "'payment_date='+value")}) %>
</p>
<p>Prueba
<%= collection_select "", :object, Operation.all, :id, :taker_id, { :onChange => "javascript::alert('hola');", :onClick => remote_function(:url => {:controller => 'operations', :action => "update_payment_date"}, :with => "'dgdfg='+value")} %>
</p>
<p>Monto a Cancelar (Mayor a cero):<br/><br/>
<%= text_field_tag :ammount , #operation.get_balance(#operation.interest_rate_for_taker) %>
</p>
<p>Monto punitorio:<br/><br/>
<%= text_field_tag :punitive_ammount, #punitive_ammount %>
</p>
<!--<p>Fecha de Pago:<br/><br/>
<%#= date_select("", :date, :start_year => Time.now.year-1, :default => Time.now) %>
</p>-->
<% %>
<p>
<%= f.submit 'Cancelar' %>
</p>
<% end %>
Hi format of date_select helper is
date_select(object_name, method, options = {}, html_options = {})
you have
<%= date_select("", :payment_date, {:start_date => Time.now, :onchange => remote_function(:url => {:controller => 'operations', :action => "update_payment_date"}, :with => "'payment_date='+value")}) %>
try
<%= date_select("", :payment_date, {:start_date => Time.now}, {:onchange =>"javascript::alert('hola');"}) %>
the same about collection_select
collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {})
you have
<%= collection_select "", :object, Operation.all, :id, :taker_id, { :onChange => "javascript::alert('hola');", :onClick => remote_function(:url => {:controller => 'operations', :action => "update_payment_date"}, :with => "'dgdfg='+value")} %>
try
<%= collection_select "", :object, Operation.all, :id, :taker_id, {}, { :onChange => "javascript::alert('hola');"}%>
I'm trying to pass a string with a link_to_remote call as the :id, and the string should be collected from an input field with and id of "movie_title".
<div id="search_list">Nothing here yet</div>
<br />
<% semantic_form_for #movie do |f| %>
<% f.inputs do -%>
<%= f.input :title, :class => "movie_title" %> <%= link_to_remote( 'Search...', { :url => { :action => :imdb_search, :id => "'+$('\#movie_title').value+'" } }, { :title => "Search for this movie", :class => "imdb_search" } ) -%>
[...removed text that does not matter...]
<% end -%>
<%= f.buttons %>
<% end %>
I keep getting an javascript error, and if I remove the # from the jquery in the link, it returns "Undefined".
The link I get is:
<a class="imdb_search" href="#" onclick="jQuery.ajax({data:'authenticity_token=' + encodeURIComponent('yHPHYTZsPTQLi9JYSauUYcoie/pqPPk2uHBTN0PzNsQ='), dataType:'script', type:'post', url:'/movies/imdb_search/'+$('%23movie_title').value+''}); return false;" title="Search for this movie">Search...</a>
So I want the link updated with the contents of movie_title.
How do I do that?
I'd try something like
<%= link_to_remote( 'Search...', {
:url => { :action => :imdb_search},
:with => "'id=' + $('movie_title').value",
{:title => "Search for this movie", :class => "imdb_search"}
)
Fixed it
Used:
$('movie_title').val()
Insted of
$('movie_title').value
