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

For convenience, add this macro first.

_formhelpers.html:

{% macro render_field(field) %}
  
{{ field.label }}
  
{{ field(**kwargs)|safe }}
  {% if field.errors %}
    

    {% for error in field.errors %}
      
{{ error }}
    {% endfor %}
    
  {% endif %}
  
{% endmacro %}

Import this macro and code in this way. it should work.

{% from "_formhelpers.html" import render_field %}

    {{ render_field(form.content,rows=100, cols=100) }}

Hope it helps !
