您好我正在尝试更改以下内容:
.form-group
= label_tag :metric, 'Metric', class: 'sr-only'
= select_tag :metric, options_for_select(Report::METRICS, selected: @report.metric), class: 'form-control'
类似于以下内容:
.form-group.pull-left
= label_tag :metric, 'Metric', class: 'sr-only'
.btn-group{"data-toggle" => "buttons"}
%label.btn.btn-default.active
%input#option1{name: "options", type: "radio", value: "value1"}/
Value1
%label.btn.btn-default
%input#option2{name: "options", type: "radio", value: "value2"}/
Value2
但问题是,当我提交表单时,它实际上并没有提交单选按钮值。在提交之后,当它应保留在所选单选按钮上时,它默认为无选择。

您可以使用radio_button_tag
帮助程序并正确设置checked
参数。
使用您的示例,它是这样的:
.form-group.pull-left
= label_tag :metric, 'Metric', class: 'sr-only'
.btn-group{"data-toggle" => "buttons"}
%label.btn.btn-default.active
= radio_button_tag('options', 'value1', params[:options] == 'value1')
Value1
%label.btn.btn-default
= radio_button_tag('options', 'value2', params[:options] == 'value2')
Value2
