I am write:
<%= form_for(current_user, :remote => true) do %>
<p>
<%= label_tag t("language") %>:
<%= select_tag "language", options_for_select([["Русский", "rus"], ["English", "eng"]]) %>
</p>
<p><%= submit_tag t "options.save" %></p>
<% end %>

But, value in db doesn't updated
<%= form_for(current_user, :remote => true) do |f| %>
<p>
<%= f.label :language, t("language") %>:
<%= f.select :language, options_for_select([["Русский", "rus"], ["English", "eng"]]) %>
</p>
<p><%= f.submit t "options.save" %></p>
<% end %>
Notice the variable |f| and change of label_tag, select_tag and submit_tag to f.label, f.select and f.submit
In rails form_for and corresponding form_buider object(|f|) are used to group values under a common key, which rails can understand. *_tag helpers are generally used to pass unrelated parameters.

I have a simple form as follows
<% provide(:title, 'View Mail') %>
<h1>View Mail</h1>
<div class="row">
<%= form_tag('/mails/new') %>
<%= label_tag "Email Address" %><%= email_field_tag(:email) %><br>
<%= label_tag "Password" %><%= password_field_tag(:password) %><br>
<%= submit_tag "View my Mails" %>
</div>
<% end %>
What I actually want to do is capture the email and password field and forward them to another controller 'mails' so that I can use the value of email and password in that controller and then show the appropriate details.This is just a sample app for me to check something as I am new to rails.
What exactly should be in place of
<%= form_tag('/mails/new') %>
<% provide(:title, 'View Mail') %>
<h1>View Mail</h1>
<div class="row">
<%= form_tag('/mails/new') do %>
<%= label :email %>
<%= text_field :email) %><br>
<%= label :password %>
<%= password_field :password %><br>
<%= submit_tag "View my Mails" %>
<% end %>
</div>
<% end %>
You need to define 'mails/new' path, in config/routes.db to be able to access that path.
Hopefully it answers your problem.
I'm trying to create inline radio buttons which also has its label inline (at the very left).
As I state in the title, using Bootstrap and SimpleForm.
My code looks like this:
<%= f.input :breakdown_or_size,
:collection => ["Breakdown", "Manual"],
:as => :radio_buttons,
:item_wrapper_class => 'inline',
:label => 'Select One: ' %>
This is what I get:
(source: webpagescreenshot.info)
I looked high and low for simple_form_for help. In the end I couldn't find anything, but at least with form_for you can do this:
<%= form_for(#book) do |f| %>
<% if #book.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#book.errors.count, "error") %> prohibited this book from being saved:</h2>
<ul>
<% #book.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="actions", style='inline'>
<%= f.label 'Select One: ' %>
<br/>
<%= f.radio_button :collection, "Breakdown" %> Breakdown
<%= f.radio_button :collection, "Manual" %> Manual
<br/>
<%= f.submit %>
</div>
Which at least solves the inline rendering.
I am trying to render a partial which I have set up as the following. I have am also trying to create a nested form whereby I have included accepts_nested_attributes_for :user in my hospital_bookings model. I seem to be getting the following error:
NameError in Rota_days#index
Showing
C:/Users/home/Desktop/Portal/app/views/rota_days/index.html.erb
where line #31 raised:
undefined local variable or method `hospital_booking' for
which is pointing to the following line <%= render :partial => "booking_dialog", :locals => { :booking => hospital_booking.new } %> of my index.html.erb as shown below. I thought it was something to do with my pluralization. By changing hospital_bookings.new to hospital_booking.new but this did not work
_booking_dialog.html.erb
<%= form_for booking do |f| %>
<%= f.fields_for :user do |f| %>
<br/>
<%= f.label :name %>
<br/>
<%= f.text_field :name %>
<%= f.hidden_field :hospital_id %>
<%= f.hidden_field :id unless booking.new_record? %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
hospital_booking.new is nonsensical: you have no local variable named hospital_booking. If you want a new instance of the HospitalBooking model, then you want HospitalBooking.new.
So:
<%= render :partial => "booking_dialog", :locals => { :booking => HospitalBooking.new } %>
Update (from the comments)
In the booking_dialog form partial, you need to put the name attribute on the associated user record inside a fields_for block, to distinguish it from the fields for the parent (booking):
<%= form_for booking do |f| %>
<%= fields_for :user do |user_fields| %>
<%= user_fields.label :name %>
<%= user_fields.text_field :name %>
<% end %>
<%= f.hidden_field :hospital_id %>
<%= f.hidden_field :id unless booking.new_record? %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
p.s. it seems very strange that you have a hidden field for the :id in here. You shouldn't need that.
right now I have two forms in a row
<section>
<%= render 'shared/micropost_form_purchase' %>
<%= render 'shared/micropost_form_sale' %>
</section>
then for _micropost_form_purchase.html.erb
<%= form_for(#micropost) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= f.hidden_field_tag :type, :value => "purchase" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
and for _micropost_form_sale.html.erb I have
<%= form_for(#micropost, :html => { :id => "sale" }) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= f.hidden_field_tag :type, :value => "sale" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
so I want the first micro post to automatically become a purchase micropost (I have a column in the micropost database called type that is a string that I want to depict either sale or purchase) and for the second one I want it to become a sale micropost. I was using hidden_field_tag because I thought you didn't have to define it in the controller, but am I wrong? Is hidden_field more appropriate? how can I use hidden_field_tag?
You can use:
<%= f.hidden_field :type, :value => "sale" %>
or:
<%= hidden_field_tag 'micropost[type]', "sale" %>
but not:
<%= f.hidden_field_tag :type, :value => "sale" %>
Using f.hidden_field will use the value from the variable #micropost, whereas hidden_field_tag will not use that.
It should be f.hidden_field not f.hidden_field_tag as you're using the model's form helpers :)
I have what should be a super simple form which I'm trying to use to update multiple records at once. I'm on Rails 3. I've been through all of the railscasts, etc and am pulling my hair out at this point. I'm using Devise, and have a contacts controller. Users have_many :contacts, and accepts_nested_attributes_for :contacts. The form looks like:
<%= form_for #user, :url => '/updateusercontacts' do |i| %>
<%= i.fields_for :contacts do |f| %>
<%= f.label :first_name %>
<%= f.text_field :firstname %>
<%= f.label :last_name %>
<%= f.text_field :lastname %>
<%= f.label :phone_number %>
<%= f.text_field :phonenumber %>
<%= f.label :user_id %>
<%= f.text_field :id %>
<p>
<% end %>
The form displays properly, but then on submit I get "Can't find Contact without an ID". The controller looks like:
def updatecontacts
#contacts = Contact.find(params[:id])
#contacts.each do |contact|
contact.update_attributes(params[:id])
end
render '/home'
end
The parameters seem correct, and the id's seem to be present and correct, but I can't get the save to work! I'm sure I'm missing something obvious here.
Try to remove the fields_for and when you invoke your find, use this [:user][:contacts]
your code should look like this.
View:
<%= form_for #user, :url => '/updateusercontacts' do |i| %>
<%= i.label :first_name %>
<%= i.text_field :firstname %>
<%= i.label :last_name %>
<%= i.text_field :lastname %>
<%= i.label :phone_number %>
<%= i.text_field :phonenumber %>
<%= i.label :user_id %>
<%= i.text_field :id %>
<p>
<% end %>
Controller
def updatecontacts
#contacts = Contact.find(params[:user][:contacts])
#contacts.each do |contact|
contact.update_attributes(params[:user][:contacts])
end
render '/home'
end
Hope this works.
