API Layout

class layout.BaseInput(name, value, **kwargs)

A base class to reduce the amount of code in the Input classes.

render(form, form_style, context, template_pack=<SimpleLazyObject: 'bootstrap'>, **kwargs)

class layout.Button(*args, **kwargs)

Note

class layout.ButtonHolder(*fields, **kwargs)

Layout object. It wraps fields in a <div class=”buttonHolder”>

This is where you should put Layout objects that render to form buttons like Submit. It should only hold HTML and BaseInput inherited objects.

Example:

ButtonHolder(
    HTML(<span style="display: hidden;">Information Saved</span>),
    Submit('Save', 'Save')
)

class layout.Column(*fields, **kwargs)

Layout object. It wraps fields in a div so the wrapper can be used as a column. Example:

Column('form_field_1', 'form_field_2')

Depending on the template, css class associated to the div is formColumn, row, or nothing. For this last case, you

must provide css classes. Example:

Column('form_field_1', 'form_field_2', css_class='col-xs-6',)

class layout.Div(*fields, **kwargs)

Layout object. It wraps fields in a <div>

You can set css_id for a DOM id and css_class for a DOM class. Example:

Div('form_field_1', 'form_field_2', css_id='div-example', css_class='divs')

class layout.Field(*args, **kwargs)

Layout object, It contains one field name, and you can add attributes to it easily. For setting class attributes, you need to use css_class, as class is a Python keyword.

Example:

Field('field_name', style="color: #333;", css_class="whatever", id="field_name")

class layout.Fieldset(legend, *fields, **kwargs)

Layout object. It wraps fields in a <fieldset>

Example:

Fieldset("Text for the legend",
    'form_field_1',
    'form_field_2'
)

The first parameter is the text for the fieldset legend. This text is context aware, so you can do things like:

Fieldset("Data for {{ user.username }}",
    'form_field_1',
    'form_field_2'
)

class layout.HTML(html)

Layout object. It can contain pure HTML and it has access to the whole context of the page where the form is being rendered.

Examples:

HTML("{% if saved %}Data saved{% endif %}")
HTML('<input type="hidden" name="{{ step_field }}" value="{{ step0 }}" />')

class layout.Hidden(name, value, **kwargs)

Used to create a Hidden input descriptor for the {% crispy %} template tag.

class layout.Layout(*fields)

Form Layout. It is conformed by Layout objects: Fieldset, Row, Column, MultiField, HTML, ButtonHolder, Button, Hidden, Reset, Submit and fields. Form fields have to be strings. Layout objects Fieldset, Row, Column, MultiField and ButtonHolder can hold other Layout objects within. Though ButtonHolder should only hold HTML and BaseInput inherited classes: Button, Hidden, Reset and Submit.

Example:

helper.layout = Layout(
    Fieldset('Company data',
        'is_company'
    ),
    Fieldset(_('Contact details'),
        'email',
        Row('password1', 'password2'),
        'first_name',
        'last_name',
        HTML('<img src="/media/somepicture.jpg"/>'),
        'company'
    ),
    ButtonHolder(
        Submit('Save', 'Save', css_class='button white'),
    ),
)

        {'style': 'width: 30px;'},
        {'class': 'second_widget_class'}
    ),
