ruby on rails - How to use If,else in form_for helper to extract specific field -

i have following code in edit view:

<%= form_for @content |f|%>   <% if f.text_field :home %>     <%= f.label :home %>     <%= f.text_field :home %>   <% elsif f.text_field :aboutus %>   <%= f.label :abouts %>   <%= f.text_field :aboutus %>  <% end %> <%= f.submit%> 

here @content contain following information:

id: "1", home: "staticcontent", aboutus: "staticcontent" 

so wants if wants edit home page can see home submission form , if choose aboutus, can see edit form page us.suggest me whats correct way use if,else in block?

you pass url param , work that. example:

# in view <%= link_to "edit homepage", edit_content_path(page: "home") # link /contents/:id/edit?page=home 

then in form:

<%= form_for @content |f|%>   <% if params[:page] == "home" %>     <%= f.label :home %>     <%= f.text_field :home %>   <% else %>     <%= f.label :about_us %>     <%= f.text_field :about_us %>  <% end %> <%= f.submit%> 

notice downcased labels, , changed aboutus about_us label displays correctly.
