form for - Rails form_for select default option -


i have form_for select options being defined within model. trying display placeholder option 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' } |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 dropdown menu displaying word "collection" @ top of (see screenshot below). how read of that. ideally want have dropdown menu placeholder of "names" displayed @ top when dropdown menu opened. screenshot of issue

for text field try like:

<%= f.text_field :title, :class => 'text_field', value: 'my_default_value' %>

for select try:

<%= f.select :name, factoid::names %>

see the docs select , the rails guide typical usage (i think method i've shown not work upon submitting form, see guides linked explanation, i'm not sure though).

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
