    copied!<p>I have a template which allows the user to edit their user information.</p> <pre><code>&lt;form method="post"&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt;Username:&lt;/td&gt; &lt;td&gt;{{user['username']}}&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;New Password:&lt;/td&gt; &lt;td&gt; &lt;input type="password" name="password"&gt;&lt;/td&gt; &lt;td&gt;{% if form.password.errors %} {{form.password.errors}} {% endif %}&lt;td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Re-enter Password:&lt;/td&gt; &lt;td&gt; &lt;input type="password" name="confirm_password"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;input type='hidden' name='username' value="{{user['username']}}"&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="submit" value="Submit"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <p>I also have a view function for handling such edits by the user. The database I am currently using is <a href="http://en.wikipedia.org/wiki/MongoDB" rel="nofollow">MongoDB</a> with the <a href="http://pypi.python.org/pypi/mongokit" rel="nofollow">MongoKit</a> module. I have only been able to do up to this so far in the view function, yet with no luck.</p> <pre><code>def edit(): username = request.args.get('user') user = User.find_one({'username':username}) # Is this a correct way of doing it? form = UserForm(**what should be placed here?**, obj=user) if request.method == 'POST' and form.validate(): form.populate_obj(user) user.save() return 'updated' return render_template('edituser.html', form=form, user=user) </code></pre> <p>I am going through <a href="http://wtforms.simplecodes.com/docs/0.6.1/forms.html#wtforms.form.Form.populate_obj" rel="nofollow">populate_obj(obj)</a> for this purpose. I couldn't find much help in this matter. What should I do in order to get <code>populate_obj()</code> working?</p>
