Question

I have a simple model forms, that is being rendered through the following jinja2 template:

<form method="POST" action=""> 
    <table>
      {% for field in form %}   

      <tr>{{ field.label }}</tr>
      <tr>{{ field()|safe }}</tr>

      <tr>
        {% if field.errors %}
        <td>
          <ul class=errors>
            {% for error in field.errors %}
            <li>{{ error }}</li>
            {% endfor %}
          </ul>
        </td>
        {% endif %}
        {% endfor %}
    </table>
    <input type="submit" class="btn"  value="Submit Form"/>
  </form>

I wanted to customize the output of the wtforms and to each of the form fields being rendered, i wanted to add a class "required" to use a jquery client side validation plugin.

Following is my appengine db model:

class Song(db.Model):
    title = db.StringProperty()
    lyrics = db.TextProperty()
    duration = db.IntegerProperty()
    movie = db.ReferenceProperty(Movie)
    singer = db.ReferenceProperty(Singer)

and following is my form, rendering script:

SubTaskForm = model_form(Song, 
                         exclude=('movie', 'singer'),
                         )

What would be a good way to attach validators using wtfroms validators, also how can i attach a class=required to the form fields?

Let me know how to do it.

Answer 1

One way would be to override the stuff in python, where you define them, another thing that can be done is, you might try in the templates itself, <tr class="required">
Give it a try, should work.
