Use a Login form with Mechanize

Question

I know there are very similar posts to this on Stackoverflow but I still can't seem to figure out what is wrong with my attempt.

# login to the site 
mech.get(base_URL) do |page|
  l = page.form_with(:action => "/site/login/") do |f|
    username_field = f.field_with(:name => "LoginForm[username]")
    username_field.value = userName
    password_field = f.field_with(:name => "LoginForm[password]")
    password_field.value = password
    f.submit
  end
end

Here is my error:

rb:18:in `block (2 levels) in <main>': undefined method `field_with' for nil:NilClass (NoMethodError)

Here is the HTML

<div class="bucketbody">

    <div class="form padding10">
    <form id="login-form" action="/site/login" method="post">
        <div class="row">
            <p class="note float_right">Fields with <span class="required">*</span> are required.</p>
            <label for="LoginForm_username" class="required">Email address <span class="required">*</span></label>              <input class="width_66per" autofocus="" name="LoginForm[username]" id="LoginForm_username" type="text">                         </div>

        <div class="row">
            <label for="LoginForm_password" class="required">Password <span class="required">*</span></label>               <input class="width_66per" name="LoginForm[password]" id="LoginForm_password" type="password">                          </div>

                    <div class="row rememberMe nolabel">
            <span class="field"><input id="ytLoginForm_rememberMe" value="0" name="LoginForm[rememberMe]" type="hidden"><input name="LoginForm[rememberMe]" id="LoginForm_rememberMe" value="1" type="checkbox">                <label for="LoginForm_rememberMe">Remember me on this computer</label>                              </span>
        </div>

        <p class="note"><a href="http://test.XXXXXXXX.com/user/reset">Forgot your password?</a></p>

        <div class="row buttons" style="padding-left: 0px;">
            <input class="pushButton" name="yt0" value="Login" type="submit">           </div>

    </form>     </div><!-- form -->

Answer 1

Why don't you send the post request directly? Try this:

respond = mech.post('www.mysite.com/site/login', "LoginForm[username]" => userName,    "LoginForm[password]" => password)

If you know the target (/site/login), the request method (post), and the params you must send, do the post request without messing with the form.

Let me know if it worked.

Answer 2

You're making it more complicated than it needs to be:

page = mech.get base_URL

form = page.form # page.forms[1], etc.
form['LoginForm[username]'] = userName
form['LoginForm[password]'] = password

l = form.submit form.button
