why is my text_field getting a default value of current_user.email?

I have a form containing a text field along the lines of:

<%= form_for(wizard, :url => wizard_path, :method => :put) do |f| %>     ....     <%= form.text_field "gas_credentials[user_id]", :value => wizard.gas_credentials['user_id'] %>     .... <% end %>

Mysteriously, when wizard.gas_credentials is nil, the text_field gets initial text equal to the current_user.email (which in this case is admin@admin.com). At the very least, I'd expect an error trying to call on nil.

What's especially odd is that the wizard model knows nothing about current_user, so I don't see where it's getting that value from. Can anyone shed light on what might be happening, or at least how text_field decides to compute its :value?

TIA

Doh! The answer: browser autocompletion. I'm leaving this post in place rather than deleting it out of shame in the faint hope that it might save someone else a few minutes of head scratching.

[silly forum code won't let me edit previous reply.]

To prevent autocompletion, you can do something like:

    <%= form.text_field "gas_credentials[user_id]",             :value => wizard.gas_credentials['user_id'],             :autocomplete => :off     %>

That's because it's a mailing list... and even if every other subscriber let you come around to their house and edit their emails, I wouldn't :wink:
