Web Forms With WTF! - Flask Fridays #5

In this video we'll start to use Web Forms for our Flask project with WTF (What the Forms!).

Web forms with WTF are incredibly easy to use and come with all sorts of features that we need like form validation, CSRF token creation, and even reCAPTCHA.

You can always build out web forms by hand, but using a 3rd party system like WTF just makes it so much easier!

In this video we'll look at FlaskForm, StringField, SubmitField, and the DataRequired validator.

2023: [Bug Fix] You need to add {{ form.csrf_token }} before or after this line {{ form.hidden_tag() }} on the name.html page. Else if form.validate_on_submit() == False

This is a great series of videos. Thanks!

I have no words to describe my gratitude for this series of videos. In addition to being extremely educational and educational, they are so realistic that I am applying them to an educational project that I am developing with a group of friends. Thank you very much for the great work. Greetings from Brazil.

Hi, I LOVE your tutorials, they are 100% on point. I'll keep on studying them with pleasure. Just a note : at 7:02, you say DataRequired() is a function, it seems to be an instance of the DataRequired class. It's only a detail but before running the code without the (), and reading the traceback, I was a bit lost :).

[lukagajinov]

Great video, very good and quick explanation. Thanks!

[nerminqulu]

I like you are smile everytime when you saying WTF

[rchocano]

Great video, very good explanation. Thank you!

[BenMrMakinesiyim]

it's a hard framework to learn. Soooo many methods and references in there. But thank you anyways for every detail.

As usual, clear and concise. Anyone know why I should use wtforms over typical html input tags with specified types (email, password, etc.) and properties (required, title, etc.)?

[hiwab]

I like before seeing your vids! Because i know it gonna be so good -:)

[expressionamidstcacophony]

This is one of those cases where youtube videos are more helpful documentation than the actual documentation. Dear oh dear.

I looked at many Flask tutorials and yours is the only one that helped me find a solution to this simple form. Took me a few hours to fix some bugs though.

I was very confused with the attributes that we have to pass to the render_template "name=name" and "form=form". What exactly does this part do in the code?

[salmantas]

in case of is there any one wondering how to change button text other than submit: just pass what you want into the SubmitField that you created in your class. for example: submit = SubmitField('sometext')

[andrewsweeney]

Is there a tutorial for adding

1. Date time picker to the form?
2. Multi select dropdowns?

[stephontidd]

cant get bootstrap to reflect changes in name.html EX: {{ form.name.label( class = "form-label" ) }} doesnt change the look
