wtforms

I've been curious lately what the benefits of using WTForms to submit data to flask is? Plain HTML, JavaScript, or bootstrap form seem easier to style and easier to submit with. Plus you can leave out all the python code required to create a WTForms class. Can someone explain what an advantage would be? I could say CSRF protection is one of the greatest reasons, but there are a lot of reasons why one would use WTFroms over plain HTML forms. CSRF protection out of the box Form validation out the box WTForms come as classes, so all the good come's from an object form. basically, if your project

I am trying to make a form to upload a file, but the file data is not being sent with the request. I'm manually navigating to my file and hitting submit. My FileRequired validator fails. (And if I don't include it the data field on form.scan_file is empty.) Here's my form: from flask_wtf import FlaskForm from flask_wtf.file import FileField, FileAllowed, FileRequired class ScanForm(FlaskForm): scan_file = FileField(validators=[FileAllowed(['nii', 'nii.gz', 'zip']), FileRequired()]) Here's my views.py : from flask import Blueprint, render_template, request, flash, redirect, url_for, session

The WTForms documentation is woefully inadequate, they don't even show you one single example of a custom widget that isn't derived from another widget already. I am trying to make a button type, that isn't an <input> in html: submit = InlineButton(name='submit', type='submit', title='Save this page', textWithinSpan='Save') This is what I'm trying: from flask.ext.wtf import Required, Length, EqualTo, Field, TextInput, html_params from flask import Markup class InlineButtonWidget(object): text = '' html_params = staticmethod(html_params) def __init__(self, input_type='submit', **kwargs): self

This [example][1] to set up a form with WTForms and SQLAlchemy in Flask and add a QuerySelectField to the form works. I am not using flask.ext.sqlalchemy , my code: ContentForm = model_form(Content, base_class=Form) ContentForm.author = QuerySelectField('Author', get_label="name") myform = ContentForm(request.form, content) myform.author.query = query_get_all(Authors) Now I want to set the default value of the QuerySelectField's selectlist . Tried passing a default kwarg in QuerySelectField and setting selected attributes. Nothing worked. Am I missing something obvious? Can someone help? You

I have three identical SelectField inputs in a form, each with the same set of options. I can't use one multiple select. I want to make sure that the user selects three different choices for these three fields. In custom validation, it appears that you can only reference one field at a time, not compare the value of this field to others. How can I do that? Thanks! You can override validate in your Form ... class MyForm(Form): select1 = SelectField('Select 1', ...) select2 = SelectField('Select 2', ...) select3 = SelectField('Select 3', ...) def validate(self): if not Form.validate(self):
