[英]simple_form adding attributes with no value
I'm using simple_form under a Rails 3.2 app with AngularJS and haml. 我在带有AngularJS和haml的Rails 3.2应用程序下使用simple_form。
I've got this input field where we are storing a cost and I would like to use the angularjs directive 'form-cents-to-dollars' but the simple_form input_html options require a key with a value, this is just the key or attribute as AngularJS calls it. 我已经在此输入字段中存储了成本,我想使用angularjs指令“ form-cents-to-dollars”,但simple_form input_html选项需要一个带有值的键,这只是键或属性就像AngularJS所说的那样。
= f.input :cost_per_unit_cents,
input_html: {class: 'money',
"ng-model" => "timesheet.cost_per_unit_cents",
"ng-init" => "timesheet.cost_per_unit_cents=#{@timesheet.cost_per_unit_cents}",
"ng-change" => "line_item_service.calc_total()",
"form-cents-to-dollars" }
The error I get when running this code is 'syntax error, unexpected }, expecting =>. 运行此代码时出现的错误是“语法错误,意外的},期望=>。
Is it possible to set just the 'key' using simple form? 是否可以使用简单的形式仅设置“键”? Or is there a way to send it to AngularJS as a key/value pair which would work with the attribute directive?
还是有一种方法可以将它作为可以与attribute指令一起使用的键/值对发送给AngularJS?
Somewhat hacky, but you can always use an empty string as your value. 有点骇人听闻,但您始终可以使用空字符串作为值。
= f.input :cost_per_unit_cents,
input_html: {class: 'money',
"ng-model" => "timesheet.cost_per_unit_cents",
"ng-init" => "timesheet.cost_per_unit_cents=#{@timesheet.cost_per_unit_cents}",
"ng-change" => "line_item_service.calc_total()",
"form-cents-to-dollars" => "" }
Rails will drop the empty string and add form-cents-to-dollars as an attribute on the input element. Rails将丢弃空字符串,并在输入元素上添加form-cents-to-dollars作为属性。
