Difference between form_tag and form_for

at 12:32 PM Posted by Sriram

form_for
It is used for a particular model and it is a object dependent form

<% form_for(:name, @name, :url => path, :html { } do|f| %>
<%= f.text_field :name %>

<%= f.password_field :password %>
<% end %>

In the above "form_for" tag ":name" is model name , "@name" is object which is created to access the record , url => path(specify the path here) , :html { } this is the optional attribute in this we can specify the method based on REST . In the

form_tag is the normal tag which is used for normal fields means the fields which are not based on the model and the database .
for example
if we need a search field then we go with form_tag.

<% form_tag '/name' do -%>
<%= text_field_tag "name", "username" %>
<% end %>
