Activeadmin and Formtastic: form not responding to :size

I am trying to format a form and the text fields respond to some methods, and not others.

I can do things like:

f.input :name, :input_html => { :maxlength => 10 }
f.input :name, :input_html => { :disabled => true }

But if I try to do any of the following, they do not work:

f.input :name, :input_html => { :size => 10 }
f.input :name, :input_html => { :class => 'autogrow' }
f.input :name, :input_html => { :rows => 10, :cols => 10 }

When I try using :size, for instance, the generated html shows that size=10, but is not reflected in the actual form.

These were more or less pulled right from the Formtastic documentation on Github, which the Activeadmin documentation refers to.

i had the same problem. i wanted a nested form for edit with custom text field size.this worked for me.

    form do |f|
      f.inputs "Header" do
        cf.input :name, :input_html => { :class => 'some_style', :rows => 2, :style => 'width:50%'}
      end
      f.actions
    end

so basically u have to create your own class or just work with the :style.

For nested form u can use this code

    form do |f|
      f.inputs "Header" do
        f.has_many :name,:allow_destroy => true,:new_record => true do |cf|
          cf.input :first_name, :input_html => { :class => 'some_style', :rows => 2, :style => 'width:50%'}
        end
      end
      f.actions
    end

I am not sure if your question is solved or not.

However according to Formastic Official WIKI, your code should work:

Customize HTML attributes for any input using the :input_html option. Typically this is used to disable the input, change the size of a text field, change the rows in a textarea, or even to add a special class to an input to attach special behavior like autogrow textareas:

<%= semantic_form_for @post do |f| %>
  <%= f.inputs do %>
    <%= f.input :title,      :input_html => { :size => 10 } %>
    <%= f.input :body,       :input_html => { :class => 'autogrow', :rows => 10, :cols => 20, :maxlength => 10  } %>
    <%= f.input :created_at, :input_html => { :disabled => true } %>
    <%= f.input :updated_at, :input_html => { :readonly => true } %>
  <% end %>
  <%= f.actions %>
<% end %>

if your code doesn't work , please check out the error logs, or put more debug info to your erb file, to see if you r rails is running under production mode.
