FlaskForm had to reload select choices

I am new to Python and Flask. I am trying to use WTForm FlaskForm, and having problems with choices in SelectField. I am building my forms like this.

class FightForm(FlaskForm):
    fight_id = StringField('fight_id', render_kw={'readonly': True})
    fight_type_id = SelectField('fight_type_id', 
        choices=[(t.fight_type_id, t.type_name) for t in fight_type.query.all()], validate_choice=False, validators=[DataRequired()])

These choices appear to only load 1 time. If I go add a new fight_type, I have to stop the application and restart if for it to refresh.

Also, I found this answer, flask wtforms selectfield choices not update, but FlaskForm does not trigger the __init__ function this suggests.

I changed it temporarily to Form anyway and got an error saying fight_type_id does not belong to form (paraphrasing).

I would like for these to refresh every time I call the page.

I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
