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'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 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 have a form_for select where the options are being defined from within the model. I am trying to get it to display a placeholder option but cannot figure out how to.
The Model:
class Factoid < ActiveRecord::Base
attr_accessible :description, :name, :title
validates_presence_of :description, :name, :title
validates_uniqueness_of :title
NAMES = "Angela", "Geordie", "Jared", "Jennifer", "Kevin", "Matthew", "Oscar", "Owen", "Regina", "Todd", "Vaibhavi", "Zack"
UNRANSACKABLE_ATTRIBUTES = ["id", "updated_at"]
def self.ransackable_attributes auth_object = nil
(column_names - UNRANSACKABLE_ATTRIBUTES) + _ransackers.keys
end
end
The Form:
<%= form_for #factoid, :html => { :class => 'form-horizontal' } do |f| %>
<div class="control-group">
<%= f.label :title, :class => 'control-label' %>
<div class="controls">
<%= f.text_field :title, :class => 'text_field' %>
</div>
</div>
<div class="control-group">
<%= f.label :description, :class => 'control-label' %>
<div class="controls">
<%= f.text_area :description, :class => 'text_area' %>
</div>
</div>
<div class="control-group">
<%= f.label :name, :class => 'control-label' %>
<div class="controls">
<%= f.select :name, :collection => Factoid::NAMES %>
</div>
</div>
<div class="form-actions">
<%= f.submit nil, :class => 'btn btn-primary' %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
factoids_path, :class => 'btn' %>
</div>
<% end %>
The second issue is that the dropdown menu is displaying the word "collection" at the top of it (See screenshot below). How do I get read of that. Ideally I want to have a dropdown menu with a placeholder of "Names" that is also displayed at the top when the dropdown menu is opened.
For your text field try something like:
<%= f.text_field :title, :class => 'text_field', value: 'my_default_value' %>
for your select try:
<%= f.select :name, Factoid::NAMES %>
See the docs for select and the rails guide for typical usage (I think the method I've shown you will not work upon submitting the form, see the guides linked for explanation, I'm not sure though).
I'm trying to submit a form that contains fields for both an event and an invitation to that event. Here is my form:
<%= simple_form_for(#event) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :title %>
<%= f.input :description %>
<%= f.input :start_at %>
<%= f.input :end_at %>
<%= f.input :all_day %>
<%= f.hidden_field :owner_id, value: current_user.id %>
<% if false %>
<%= f.association :sitter, label_method: lambda { |s| "#{s.name}" }, collection: User.all %>
<%= f.association :group, label_method: lambda { |g| "#{g.group_name}" }, collection: Group.where(:owner_id => current_user.id) %>
<% end %>
<%= f.input :user_emails, as: :text %>
<%= form_tag event_invitations_path, :method => :post do %>_tag :user_emails %>
</div><div>
<%= label_tag "Your message:" %>
</div><div>
<%= text_area_tag :email_message %>
<% end %>
</div>
</br>
<div class="form-actions">
<%= f.button :submit, :class => 'btn-primary' %>
</div>
<% end %>
This is (perhaps obviously) not working. :user_emails is NOT part of the event or invitation model as it's a list of emails that will be used to create invitations. Basically I merged two forms, one that was accepting the email/send invitation piece and one that was accepting the event information. I think I have my controller and model set up properly to take care of this but how do i submit this information as part of the same form without getting an "undefined_method" error (since user_emails doesn't belong to events). Let me know if you want to see my model/controller.
Use FormTagHelper
<%= label_tag "User", "Email"%>
<%= text_area_tag "user_emails", "example#example.com"%>
See the documentation for more options on text_area_tag and label_tag
Hello i have a form like
<%= form_for #user,
:url => url_for(:controller => 'frontend',
:action => 'registration_completion') do |f| %>
<div class="control-group">
<%= f.label :name, "Jméno", :class => 'control-label' %>
<div class="controls">
<%= f.text_field :name, :class => 'text_field' %>
</div>
</div>
And user is displaying the form where he can see already registered values, but some of that value i want to hide if some condition (specifically i need hide value of username if it contains #) It is possible? thank you
solution: it seems that
<% if #user.name.include?('#') %>
<%= f.text_field :name %>
<% else %>
<%= f.text_field :name, :value => "" %>
<% end %>
works
I strongly suggest to put your logic inside a helper method:
module UserHelper
def name_input(instance, f, options = {})
options[:html_options] ||= {}
f.text_field :name, options[:html_options] if instance.name.include?('#')
end
end
Then in your view:
<%= name_input(#user, f, html_options: { class: 'text_field' }) %>
If you want to simply hide the value you can do:
<%= f.text_field :name, value: #user.name.include?('#') ? #user.name : '' %>
Feel free to move this to a helper method also.
To create a hidden field when the username contains an # symbol you could use the following helper method
module UserHelper
def hidden_name_field(user, f, options = {})
options[:html_options] ||= {}
if user.name.include?('#')
f.hidden_field(:name, options[:html_options])
else
f.text_field(:name, options[:html_options])
end
end
end
and use it in you form:
<%= hidden_name_field(#user, f, html_options: { class: 'text_field' }) %>
