How to specify rows and columns of a <textarea > tag using wtforms

Question

Constructing a wtforms\' TextAreaField is something like this:

content = wtf.TextAreaField(\'Content\', id=\"content-area\", validators=[validators.Required()])
         


        

Answer 1

Much simpler; use render_kw argument when creating the field:

port = IntegerField(u"HTTP port", validators=[DataRequired(), NumberRange(1025, 65535)], render_kw={'class': 'form-control'})
mytextarea = TextAreaField(u"Content", render_kw={'class': 'form-control', 'rows': 5})

And then render the file:

{{ field() }}
