Rails 两层引号的转义字符
Rails escape characters for two layers of quotations
我正在尝试将自己的百分比放入 Bootstrap 进度条中。浮点数可以很好地传递给视图,但由于某种原因 Bootstrap 进度条不想读取它。我首先猜测我没有正确转义 style
标签。
观点:
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="#{ <% @app.completion_status %> }" aria-valuemin="0" aria-valuemax="100" style="width: '#{raw(<%= number_to_percentage(@app.completion_status) %>)}';">
<%= @app.completion_status %>%
</div>
</div>
细看:
style="width: '#{raw(<%= number_to_percentage(@app.completion_status) %>)}';"
The value attempting to be passed and converted to a percentage is: `33.3333333333333` (one third)
控制器:
def set_completion
@app = App.find(params[:id])
@app.update_attribute(:completion_status,
(((@app.elements.where(completion: true).count) / (@app.elements.count).to_f) * 100 )
)
end
您是否尝试过切换 ' 和 "?
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="#{ <% @app.completion_status %> }" aria-valuemin="0" aria-valuemax="100" style='width: "#{raw(<%= number_to_percentage(@app.completion_status) %>)}";'>
<%= @app.completion_status %>%
</div>
</div>
乍一看,我发现您在 erb 标签之外使用 ruby 插值,这可能是问题所在。编辑::试试下面
style="width: <%= number_to_percentage(@app.completion_status) %>"
下面是我刚刚构建的一个,所以请尝试遵循这一点并将您的插值保留在 ERB 标签内!
<div class="progress-bar progress-bar-info progress-bar-striped"
role="progressbar" aria-valuenow="<%=@email_usage%>" aria-valuemin="0"
aria-valuemax="100" style="width: <%=@email_usage%>%">
