Using bootstrap with web.py's form - html

Question

I am using web.py in my backed to generate a form. I am also wanting to use bootstraps form class. This is a snippet from my html
<form name="test" method="POST">
$:form.render()
<input type="submit" name="button" value="Login" />
</form>
Which, when generated by web.py, turns into
<form name="login" method="POST" class = "register">
<table>
<tr><th><label for="username">Username:</label></th><td><input type="text" id="username" name="username"/></td></tr>
<tr><th><label for="password">Password:</label></th><td><input type="password" id="password" name="password"/></td></tr>
<tr><th><label for="password_again">Repeat your password:</label></th><td><input type="password" id="password_again" name="password_again"/></td></tr>
</table>
<input type="submit" value="Register" />
</form>
However. This makes it difficult to add bootstrap features to my code.
One example directly from the bootstrap website is :
<form>
<fieldset>
<legend>Legend</legend>
<label>Label name</label>
<input type="text" placeholder="Type something…">
<span class="help-block">Example block-level help text here.</span>
<label class="checkbox">
<input type="checkbox"> Check me out
</label>
<button type="submit" class="btn">Submit</button>
</fieldset>
</form>
Is it possible to add these sorts of features into my form?

Answer 1

Use $:form.render_css() instead.

Answer 2

I wrote class inherited from Form class with modified render_css method. It look like that:
class bootstrap_form(form.Form):
def render_bootstrap(self):
from web import net
out = []
out.append(self.rendernote(self.note))
for i in self.inputs:
out.append('<div class="form-group">')
if not i.is_hidden():
out.append('<label for="%s">%s</label>' % (i.id, net.websafe(i.description)))
out.append(i.pre)
out.append(i.render())
out.append(self.rendernote(i.note))
out.append(i.post)
out.append('</div>')
out.append('\n')
return ''.join(out)
I hope you'll find this useful.
