Hi,
I am trying to create a custom form builder but got the following error:
wrong argument type Class (expected Module)
To create a form builder I have to subclass
ActionView::Helpers::FormBuilder. So, I guess, it must be a class and not a
module or maybe a class wrapped inside a module....
Here is the idea:
The helper (/app/helpers/custom_form_helper.rb):
class CustomFormHelper < ActionView::Helpers::FormBuilder
def datalist_for(method, choices, options = {})
... # I'd like to render a partial here with :locals => {:list =>
choices, :name => @object_name + "[_#{method}]"}
end
end
The partial (app/view/shared):
<input type="text" name=<%= name %> list="list">
<datalist id="list">
<% choices.each do |elem| %>
<option value=<%= elem %> >
<% end %>
</datalist>
The view:
<%= form_for(:moove, :builder => "CustomFormHelper" :url => {:action =>
'create'}) do |f| %>
<table>
<tr>
<td><%= f.datalist_for(:sport, @sports)%></td>
</tr>
</table>
<% end %>
Thank you in advance for your help,
Alexandre
