Update text of submit button in wtforms

I have a form, that will be used for a new submit and updates. My question is about the text of the submit button. I want to change the text to New submit and to New update, depending on the situation. This is purely informative.

class Interview(Form):
    ...
    submit = SubmitField('New submit')

If possible, i want to avoid create a new class, with exactly same fields, only because of the text of submit.

Old question, but for anyone else coming across this, an alternative is to just set it from code before rendering the template:

if is_submit:
    form.submit.label.text = 'New submit'
else:
    form.submit.label.text = 'New update'

return render_template(...)

The correct way would be to make two forms and check which submit button is pressed at server side.

if submit_form.validate_on_submit() and submit_form.any_field.data:
        print "submit_form submit button is Pressed"
elif update_form.validate_on_submit() and update_form.any_field.data:
        print "update_form submit button is submitted"

The correct way to do this with mixins:

class InterviewMixin():
    ...

class InterviewSubmit(Form, InterviewMixin):
    submit = SubmitField('New submit')

class InterviewUpdate(Form, InterviewMixin):
    submit = SubmitField('New update')

I've solved the problem by not incorporating the submit button in the form definition, instead I add a submit button in the HTML, based on what label I want on it.

{% if pagetitle == 'Update' %}
   <p><input type="submit" name="btn" value="New Update"></p>
{% endif %}
{% if pagetitle == 'Submit' %}
   <p><input type="submit" name="btn" value="New Submit"></p>
{% endif %}

Using this way you can use the same form, and have different labels on the button, depending on which one should be used.

If you need you can use the same variable to set the action of the form, if you need to direct to different views.

Or you can use the value of the button in the view.

if flask.request.form['btn'] == 'New Update':
   ...
elif flask.request.form['btn'] == 'New Submit':
   ...
