formtastic paperclip attribute detection generates wrong html

[brainlag]

Html generated with autodetection:

<li id="model_field_input" class="string required">
     <label for=model_field">Field<abbr title="required">*</abbr></label>
     <input type="text" value="/field/original/missing.png" size="50" name="model[field]" id="model_field"/>
</li>

Html generated whenn forced to :file (:as => :file)

Field*

What's the actual name of the file upload field? Can we see the code you're using to get this output?

You're getting a "string" input rather than a "file" input because Formtastic doesn't think this field is a file upload field. There's some rudimentary checking in there (see @@file_methods config option and the code around line 1025), but without knowing the name of the attribute and some more stuff about your model, I can't write a decent (failing) test.

I think i should mention that I use Ruby 1.9.1. Not sure if this makes a difference, but I tried to run the specs last night and 95% of all testcases were failing.

Pasting in DM from brainlag so all info is one one place:

I think Formtastic thinks it is a "file" because the input box it generates with some text filled in. See the value attribute of the input field.

Model:

class Map < ActiveRecord::Base
has_many :replays

has_attached_file :image
validates_attachment_presence :image
validates_presence_of :name

end
View:

<% semantic_form_for :map, :html => {:multipart => true}, :url => maps_path do |form| %>
<% form.inputs do -%>
<%= form.input :name %>
<%= form.input :image %>
<% end -%>
<% form.buttons do -%>
<%= form.commit_button 'Create' %>
<% end -%>
<% end %>

ok, i found what is wrong

when you use semantic_form_for you should pass an instance variable and not a symbol
because if you use a symbol the autodedection breaks

so it is all my fault

good know nothing serious was broken!
