QUESTION
I am trying to make an upload form with Flask where the user needs to fill in the information needed, upload a photo, and also to pick a category provided from the database by using QuerySelectField.
When I submit the form, I get TypeError: object of type 'int' has no len().
The goal was to have different events of various types. Like cafes, Restaurants, etc. I think the problem is at if formupload.validate_on_submit():
The Error

Answered 2021-Dec-03 at 06:12The problem might be from the fields in your model. You have to use NumberRange for IntergerField instead of using Length which is for a string

I have a form with a column of checkboxes corresponding to the columns in my database. I'm setting the value of each checkbox (in javascript) to the name of the column, but when I try to read the checkbox value in Flask/Python all I can get is True or False. How do I read the text value of the value attribute of the checkboxes?
Just to complicate things, I'm generating the form as a FieldList of FormFields, so I can't simply hardcode the field names. (Well, I could, but that would make it fragile to schema changes.)

QUESTION
I want to have a form with a set of radio buttons, with each radio button controlling enablement of several other controls, and I want the other controls to be interspersed with the radio buttons. In short, I want something like this:
- Radio Button
- Check Box
- Radio Button
- Select List
- Radio Button
where each radio button enables the control immediately below it.
The problem is that Jinja2 wants to render the radio buttons as a group with nothing between them; there doesn't seem to be a clean way to reference the individual button elements.
How do I render the individual radio buttons in the Jinja2 code? I'm using WTForms 2.3.3 and Flask 2.0.1.
For reference, here's the FlaskForm:

QUESTION
I have a project that worked on ubuntu 16.04 with python 3.6 but now we are trying to make it run on ubuntu 20.04 with same python version. I need to install all requirements on the venv and apparently its only mysqlclient==1.3.12 that fails.
Went through lots of articles on stackoverflow but none of them seem to solve the problem.
Error for pip3 install mysqlclient==1.3.12
...ANSWER
Answered 2021-Oct-01 at 14:15You're using old mysqlclient 1.3.12 with new MySQL 8. Either you need to downgrade MySQL to version 5.6. Or you need to use later mysqlclient.
The incompatibility was fixed in commit a2ebbd2 on Dec 21, 2017 so you need a later version of mysqlclient.
mysqlclient 1.3.13 was released on Jun 27, 2018. Try it or any later version.
