Capitalize f.text_field

I have a form_for and I want that any value inside x.textField appear with the first letter in Upcase (I'm talking about the edit where the textfield are prefilled by the db values).

You can do this with CSS...

= f.text_field :some_attribute, style: 'text-transform: capitalize;'

you can also do this in controller's create/update action like as given below

def create

  @user = User.new(params[:user])
  @user.name = params[:user][:name].capitalize

  if @user.save
   #do something
  else
   #do something else
  end

end

Pan Thomakos's solution will work, but if you don't want to have to add :value => f.object.name.capitalize to every text field on the form, you could look into writing your own FormBuilder.

Put this somewhere in your load path, like lib/capitalizing_form_builder.rb

class CapitalizingFormBuilder < ActionView::Helpers::FormBuilder

  def text_field(method, options = {})
    @object || @template_object.instance_variable_get("@#{@object_name}")

    options['value'] = @object.send(method).to_s.capitalize

    @template.send(
      "text_field",
      @object_name,
      method,
      objectify_options(options))
    super
  end

end

Usage:

<% form_for(@post, :builder => CapitalizingFormBuilder) do |f| %>

  <p>
    <%= f.text_field :title %>
  </p>
  <p>
    <%= f.text_field :description %>
  </p>
  <p>
    <%= f.submit 'Update' %>
  </p>

<% end %>

You can capitalize it like this:

<%= form_for ... do |f| %>
  <%= f.text_field :name, :value => f.object.name.capitalize %>
