I'm trying to set up a search / filter using collection_select.
Firstly: This works. It lists all cases for employee with id = 15.
<%= form_tag(cases_path, :method => "get") do %>
<%= hidden_field_tag :param_e, 15 %>
<%= submit_tag "Filter", :name => nil %>
<% end %>
But what I want is a collection_select, so I can list cases for any employee.
<%= form_tag(cases_path, :method => "get") do %>
<%= collection_select( :x, :y, Employee.all, :id, :name, {}, { :multiple => false }) %>
<%= hidden_field_tag :param_e, :z %>
<%= submit_tag "Filter", :name => nil %>
<% end %>
This shows the collection_select with all the employees in a drop-down.
How to I connect-up the collection_select?

I'm using simple_form to create my scaffolding forms in my current project. I need some help to improve my address CRUD. After my db:seed there are lots of cities registered.
My current form for address is:
<%= simple_form_for #address, :html => { :class => 'form-horizontal' } do |f| %>
<%= f.input :street%>
<%= error_span(#address[:street]) %>
<%= f.input :zip%>
<%= error_span(#address[:zip]) %>
<%= f.label :city_id %>
<%= f.collection_select(:city_id , City.all, :id, :name, prompt: true) %>
<%= error_span(#address[:city_id]) %>
<%= f.button :submit, :class => 'btn-primary' %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
address_path, :class => 'btn btn-default' %>
<% end %>
How can I filter my citties collection bellow selecting first the state ?
<%= f.collection_select(:city_id, City.all, :id, :name, prompt: true) %>
Thanks
Add this class method to your model:
def self.by_state
order('state DESC')
end
Then use it in your form:
<%= f.collection_select(:city_id , City.by_state, :id, :name, prompt: true) %>
i'm creating a form where a user can choose a product and a quantity. I need to pass the id value from the object #event to the controller, but i dont know whats the right way to do it. As it is now, it the params[:event_id] field is always nil in the controller.
<%= form_tag logic_giveRandomGifts_path :method => 'post' %>
<div class="form-group">
<%= collection_select(:params, :product_id, Product.all, :id, :name, :prompt => true) %>
Quantidate:
<%= text_field_tag :quantity, params[:quantity], :size => 2 %>
<%= submit_tag "GO!",params[:event_id] => #event.id,:class => 'btn btn-default' %>
</div>
Add hidden filed in your form and set its value equal to #event.id
<%= form_tag logic_giveRandomGifts_path :method => 'post' %>
<div class="form-group">
<%= collection_select(:params, :product_id, Product.all, :id, :name, :prompt => true) %>
Quantidate:
<%= text_field_tag :quantity, params[:quantity], :size => 2 %>
<%= hidden_field_tag :event_id, value: #event.id%> #add this
<%= submit_tag "GO!",params[:event_id] => #event.id,:class => 'btn btn-default' %>
</div>
<% end %>
You can use now event id in your controller as params[:event_id]
<%= hidden_field_tag :event_id, #event.id %>
So this will be available in params[:event_id].
Simply pass an hidden field in form as followings
<%= hidden_field_tag :event_id, value: #event.id%>
It will available in controller as
params[:event_id]
I have form partial that allows the user to enter the subject and message that will be included in the outbound email. I want to allow the users to select the recipients of the email from the contacts that are associated with the invoice that the email belongs to. The email recipients that are selected through the nested form are to be stored in a separate table.
class EmailRecipient < ActiveRecord::Base
attr_accessible :contact_id, :email_id
belongs_to :email
end
class Email < ActiveRecord::Base
attr_accessible :subject, :message, :invoice_id, :email_recipients_attributes
belongs_to :invoice
has_many :email_recipients
accepts_nested_attributes_for :email_recipients
end
<%= simple_form_for [:invoice, #email], html: {class: "form-horizontal"} do |f| %>
<%= f.error_notification %>
<% #invoice.contacts do |c|%>
<%= f.fields_for :email_recipients do |builder| %>
<%= builder.input :contact_id, :as => :check_boxes %>
<%= c.name %><br/>
<% end %>
<% end %>
<%= f.input :subject, :as => "string" %>
<%= f.input :message, :input_html => { :class => 'span7', :rows => 10 } %>
<div class="form-actions">
<%= f.button :submit, "Send Invoice", :class => 'btn-warning' %>
<%= link_to 'Cancel', invoice_path(#invoice), :class => 'btn' %>
</div>
<% end %>
This isn't the prettiest answer, so I would love to see a better solution, but it gets the job done until my skills improve.
In the controller for the parent form I added:
#invoice.contacts.each { |c| #email.email_recipients.build(contact_id: c.id) }
This builds the records for all contacts whether they are needed or not. Then in the form partial I modified the nested form:
<%= simple_form_for [:invoice, #email], html: {class: "form-horizontal"} do |f| %>
<%= f.error_notification %>
<% count = 0 %>
<%= f.simple_fields_for :email_recipients do |email_recipients_form| %>
<%= email_recipients_form.input :_destroy, as: :boolean, :label => false do %>
<%= email_recipients_form.check_box :_destroy, {}, "false", "true" %>
<% contact = #invoice.contacts.find(#email.email_recipients[count].contact_id) %>
<%= contact.name + " (" + contact.email + ")" %>
<% end %>
<%= email_recipients_form.input :contact_id, as: :hidden %>
<% count += 1 %>
<% end %>
I've got this tripbuilder which i want to assign categories to. So I've set up the models as where a trip can have any(or more) categories that are in the category table in my database. However; i have no idea how i can set up the form allowing a user to select categories via checkbox. Since fields_for doesn't sound like a solid way to go in this case (Because i want to see all the categories with a checkbox and select as many categories as i want). Can anyone help me out?
I've tried this form:
<%= form_for #trip, :html => {:multipart => true} do |a| %>
<%= a.label :title, "Routetitel" %>
<%= a.text_field :title %>
<%= a.label :description, "Omschrijving" %>
<%= a.text_area :description %>
<%= a.fields_for :categories do |cat| %>
<%= cat.check_box :name %>
<% end %>
<%= a.submit 'Verstuur' %>
<% end %>
At first, you need to setup the relationship between trip and category like this:
class Trip < ActiveRecord::Base
has_and_belongs_to_many :categories
end
Then you can build the form like this:
<%= form_for #trip, :html => {:multipart => true} do |a| %>
<%= a.label :title, "Routetitel" %>
<%= a.text_field :title %>
<%= a.label :description, "Omschrijving" %>
<%= a.text_area :description %>
<% Category.all.each do |cat| %>
<%= check_box_tag "trip[category_ids][]", cat.id, #trip.catergory_ids.include?(cat.id)
<% end %>
<%= a.submit 'Verstuur' %>
<% end %>
Yes, it can be done by using select tag and multiple attribute of select tag.
<% = a.select :categories, Category.all.collect {|c| [c.name, c.id]}, :include_blank => true', :multiple => "multiple" %>
Please Modify your fields_for as described below and check !!!!
<%= a.fields_for "categories[]" do |cat| %>
<%= cat.check_box :name %>
<% end %>
I feel like this should be really really simple, but I'm completely stuck!
In a form I might have a field like:
<%= f.text_field :name, :class => "text" %>
On edit, this pulls back in the value submitted on create, that's fine. But I want to prevent certain fields from being edited. I know I can disable the field or hide it, but I'd like to be able to pull in the values to display and use in other ways. How do I access them?
In this case I've tried things like:
<%= f.track.name %>
<%= track.name %>
<%= #track.name %>
But none of the above work!
Any ideas folks?
EDIT: (I'm using nested forms for this)
<%= form_for(#release, :html => { :multipart => true }) do |f| %>
<h3>Upload Tracks for <%= #release.title %></h3>
<%= f.fields_for :tracks do |builder| %>
<%= render 'upload_track_fields', :f => builder %>
<% end %>
<%= f.submit "Upload Tracks", :class => "submit" %>
<% end %>
And the upload_track_fields that are rendered:
<%= f.text_field :position, :class => "text" %>
<%= f.text_field :name, :class => "text" %>
<%= f.text_field :isrc, :class => "text" %>
<%= f.text_field :version, :class => "text" %>
<%= f.file_field :track, :class => "text" %>
<%= f.hidden_field :primary_genre_id %>
<%= f.hidden_field :secondary_genre_id %>
<%= f.hidden_field :alt_primary_genre %>
<%= f.hidden_field :alt_secondary_genre %>
<%= f.hidden_field :asset_tier %>
<%= f.hidden_field :preview_start %>
<%= f.hidden_field :parental_advisory %>
<%= f.hidden_field :available_separately %>
<%= f.hidden_field :_destroy %>
I've hidden most of the fields to prevent editing, but still need to see some of the fields so they're left as text fields. I tried to disable them, but that stops any changes (specifically the file upload) working.
In short, i'd prefer to display most of the above as text rather than form fields.
In the main form:
<% index = 0 %>
<% f.fields_for :tracks do |builder| %>
<%= #release.tracks[index].name %>
<%= render 'upload_track_fields', :f => builder %>
<% index += 1 %>
<% end %>
In the nested form:
<%= f.text_field :position, :class => "text" %>
# Notice that there's no "name" attribute
<%= f.text_field :isrc, :class => "text" %>
<%= f.text_field :version, :class => "text" %>
<%= f.file_field :track, :class => "text" %>
What I did in the first snippet is dirty, but I never used fields_for so I don't know how to get the actual index. I looked in Google, but I didn't find a solution so far.
I can't try it right now, I'll do it when I'll be home.
I suggest using this while finding a way to get the index.
Good luck!
As those who have commented said, I'd assume the <%= #track.name %> should work, if you have #track = #release.track (for instance) in your edit method in the controller.
Instead of keeping track of the index you can access the associated objects through builder, it's actually a track
<% f.fields_for :tracks do |builder| %>
<%= builder.object.name %>
<%= render 'upload_track_fields', :f => builder %>
<% end %>
