Yes, it is possible to set a decimal field to zero using render_template with Flask WTForms. You can set a decimal field to zero by setting its value to 0.0 or by using the Decimal function provided by the decimal module in Python. Here is an example:
from flask import Flask, render_template
from wtforms import Form, DecimalField
from decimal import Decimal
app = Flask(__name__)
class MyForm(Form):
decimal_field = DecimalField()
@app.route('/', methods=['GET', 'POST'])
def index():
form = MyForm()
if form.validate_on_submit():
# Process form data
pass
form.decimal_field.data = Decimal('0.0') # Set the value to zero
# OR
# form.decimal_field.data = 0.0 # Set the value to zero
return render_template('index.html', form=form)
if __name__ == '__main__':
app.run(debug=True)
In the above example, we have created a form with a decimal field called decimal_field
. We have set its value to zero using the Decimal function. Alternatively, we could have set its value to 0.0 directly. We then pass the form to the render_template
function along with the name of the template file (index.html
). In the template, we can render the form field using form.decimal_field
.
