我目前正在将其用于我的新用户表单:

class UserForm(AdminPage):
    entity = Model.User
    title = 'User'
    class child(ListForm):
        css_class = 'form-horizontal'
        buttons = [SaveButton(),CancelButton()]
        ...
        phone = TextField(
                label = 'Phone',
                validator = twc.Required
        )
        ...

我假设我将不得不使用 ListForm 以外的其他东西来做我想做的事情。这是我需要的:

我想自定义某些表单字段的长度,将两个表单字段彼此相邻而不是在下方,并将这两个字段上的标签更改为显示在字段上方而不是左侧。

我花了好几个小时来研究不同版本的 tg docs 和 1.0 API,但我找不到任何有用的东西。我尝试添加:

__field_attrs__={'phone':{'rows':'2'}}

但没有任何改变。我假设 ListForm 没有field_attrs!?谁能指出我正确的方向来实现我正在寻找的东西?

非常感谢!

您可以将 CSS 类和样式添加到您的字段,如下所示:

phone = TextField(label='Phone',
                  validator=twc.Required,
                  css_class='MyTextFieldClass',
                  attrs=dict(style='display:block;width:8em', maxlength='12'))

对于完全不同的布局,您需要继承BaseLayout并引用您自己的模板,如下所述:http: //tw2core.readthedocs.org/en/latest/design/#template

例如,我创建了一个更灵活的 Layout 类,称为 FloatLayout:

from itertools import groupby
from tw2.core import Param
from tw2.forms.widgets import BaseLayout

class FloatLayout(BaseLayout):

    template = "widgets.templates.float_layout"

    aside = Param('All fields aside', default=False)

    def rows(self, children):
        """Create the rows."""
        def row_no(child, no=[0]):
            if not self.aside and not getattr(child, 'aside', False):
                no[0] += 1
            return no[0]
        return groupby(children, row_no)

它可以与这个 FloatForm 类一起使用:

from tw2.core import Variable
from tw2.forms import Form

class FloatForm(Form):
    """Form using floating divisions allowing multiple fields per row.

    Fields having the 'aside' attribute set appear on the same row.

    Something like the following should be included in the site CSS file:

    form.floatform {
        margin-bottom: 1ex;
    }
    form.floatform div.row {
        clear: left;
        overflow: hidden;
        height: 100%;
        margin-top: 1.5ex;
    }
    form.floatform div.field {
        float: left;
        margin-right: 1em;
    }
    form.floatform label.fieldlabel {
        display: block;
    }
    form.floatform div.submit {
        margin-top: 3ex;
    }

    """

    template = "widgets.templates.float_form"

    child = Variable(default=FloatLayout)

    css_class = "floatform"

FloatLayout 的 Genshi 模板 float_layout.html 是这样的:

<div xmlns:py="http://genshi.edgewall.org/" py:attrs="w.attrs" py:strip="True">
    <div py:for="row_no, row in w.rows(w.children_non_hidden)"
            class="${row_no % 2 and 'odd' or 'even'} row">
        <div py:for="child in row" py:attrs="child.container_attrs"
            class="field${child.validator and
                getattr(child.validator, 'required', None) and ' required' or ''}"
            title="${w.hover_help and w.help_text or ''}">
            <label py:if="child.label" for="${child.attrs.get('id')}"
                class="fieldlabel" py:content="child.label"/>
            <span py:replace="child.display()"/>
            <span py:if="not w.hover_help and child.help_text"
                class="fieldhelp" py:content="child.help_text"/>
            <span py:if="child.error_msg"
                class="fielderror" py:content="child.error_msg"/>
        </div>
    </div>
    <div py:if="w.children_hidden" style="display:none">
        <div py:for="child in w.children_hidden" py:replace="child.display()"/>
    </div>
</div>

FloatForm 的 Genshi 模板 float_form.html 是这样的:

<form xmlns:py="http://genshi.edgewall.org/"
    class="floatform" py:attrs="w.attrs">
    <div py:if="w.error_msg" class="formerror" py:content="w.error_msg"/>
    <div py:if="w.help_msg" class="formhelp"><p py:content="w.help_msg"/></div>
    <div py:replace="w.child.display()"/>
    <div py:for="button in w.buttons" class="field" py:content="button.display()"/>
</form>

一个具体的表单现在看起来像这样:

class UserForm(FloatForm):
    action = url('save_user')
    submit = SubmitButton('Save user')
    user_id = HiddenField(validator=IntValidator())
    user_name = TextField(validator=UserNameValidator(max=16),
        size=20, maxlength=16, label=u'User name:')
    remote_account = CheckBox(validator=BoolValidator(),
        label=u'Remote account:', aside=True)
    new_password = PasswordField(
        validator=PasswordValidator(required=False),
        size=20, maxlength=16, label=u'Password:', aside=True)
    group_id = CheckBoxList(item_validator=IntValidator(),
        label=u'Roles:', css_class='inline')
    display_name = TextField(validator=NameValidator(max=255),
        size=64, maxlength=255, label=u'Real name:')
    mail = TextField(validator=EmailIfLocalValidator(),
        size=64, maxlength=255, label=u'Email address:')

如您所见,字段remote_accountnew_password一个属性aside,使它们与 出现在同一行上user_name
