Question

我正在使用WebTest测试表单。但是，某些字段是使用JS动态创建的，因此这些字段不在表单中。当我尝试设置其中一个字段时出错：

>>> resp.form['new_field'] = 'value'
or
>>> resp.form.set('new_field', 'value')
or
>>> resp.form.set('new_field', 'value', index=0)
or 
>>> resp.form['new_field'].force_value('value')

*** AssertionError: No field by the name 'new_field' found

有没有办法创建一个字段？

Answer 1

您需要将新字段添加到字段和field_order：

from webtest.forms import Text
def add_dynamic_field(form, name, value):
    """Add an extra text field to a form. More work required to support files"""
    field = Text(form, 'input', None, None, value)
    form.fields[name] = [field]
    form.field_order.append((name, field))

add_dynamic_field(resp.form, 'newfield', 'some value')

Answer 2

更新了@lambacck代码以处理文件字段。

from webtest.forms import Text, File
from webtest import Upload


def add_dynamic_field(form, name, value):
    field_cls = File if isinstance(value, Upload) else Text
    field = field_cls(form, 'input', None, 999, value)
    form.fields[name] = [field]
    form.field_order.append((name, field))

我可以使用WebTest添加非现有字段吗？
