Re: [Cppcms-users] Setting field value after form.load() still fails validation

[Artyom B. <art...@ya...>]

If this a default value

than

- you should set it before you render the form so it would be seen in the HTML
- you should allow the widget to be empty and check if it is widget_name.set(). If it is 
  not set use default,

Using

  c.form.load(context())
  c.form.num.value(10);
  c.form.validate()

Is not correct. You should either do

  


  if(request()=="POST") {

      c.form.load(context())      c.form.validate()
  }
  else  {
      c.form.num.value(10);
      render("myform",c);
  }

Or
  Do not sent constrains on a num and then



  c.form.load(context())  c.form.validate()

  if(c.form.num.set()) {
     realval = 10;// we got default
  }
  else {
     realval = num.value();
     // do other checks
  }
