如何更改 Web2py 自动完成小部件的“_class" [英] How to change '_class' of Web2py autocomplete widget

问题描述

我遍历表单对象以更改所有类:

I loop through a form object to change all the classes:

form = crud.create(db.messages, next = URL('index'))
parts = ['title', 'body', 'subject'] # corresponding fields
classes = 'form-control col-md-12' # my classes
for p in parts:
    form.custom.widget[p]['_class'] = '%s %s' % (classes, form.custom.widget[p]['_type'])

这是有效的 - 但是:subject 是一个自动完成小部件:

This is working - but: subject is an autocomplete widget:

db.messages.subject.widget = SQLFORM.widgets.autocomplete(...)

这里 _class 没有改变(或之后又改变了?)

and here _class is not changed (or altered afterwards again?)

如何解决这个问题?谢谢！

How can this be fixed? Thanks!

推荐答案

自动完成小部件是一个 TAG 对象，它包含两个组件，第一个是 INPUT元素.因此，请执行以下操作:

The autocomplete widget is a TAG object that contains two components, the first of which is the INPUT element. So, do something like:

if p == 'subject':
    form.custom.widget[p][0].add_class(classes)

注意，您可以使用 add_class 方法向具有现有类的元素添加类.

Note, you can use the add_class method to add classes to an element that has an existing class.

此外，您可以查看将 crud.settings.formstyle 设置为bootstrap3_stacked"或bootstrap3_inline"是否适合您，而不是手动更改所有类.如果没有，您也可以编写自定义的 formstyle 函数来生成您想要的确切表单布局.

Also, instead of manually changing all the classes, you might see if setting crud.settings.formstyle to "bootstrap3_stacked" or "bootstrap3_inline" works for you. If not, you can also write a custom formstyle function to generate the exact form layout you want.
