Ruby on Rails haml sql 查询

Question

我正在向 HAML 页面传递一个参数并成功检索它。

%h1 Welcome to your History
%p
  %strong Name:
  = params[:name]

%table#houses
  %thead
    %tr
      %th Name
      %th UserName
      %th User ID
      %th Email
      %th Rented House
      %th Start Date
      %th End Date
      %th Total Cost ($)
      %th Rating

我想根据查询Select * from histories where name = params[:name]显示一个表格。

我该怎么做？

Answer 1

这很简单，并且假设您已经在控制器中执行了查询，如下所示：

def history
  @histories = History.where(name: params[:name]);
end

在您看来，您只需根据数据添加行和列：

%h1 Welcome to your History
%p
  %strong Name:
  = params[:name]

%table#houses
  %thead
    %tr
      %th Name
      %th UserName
      %th User ID
      %th Email
      %th Rented House
      %th Start Date
      %th End Date
      %th Total Cost ($)
      %th Rating
  - @histories.each do |history|
    %tr
      %td
       = history.name
      %td
       = history.user_name
      %td
       = history.user_id
      %td
       = history.email
      %td
       = history.rented_house
      %td
       = history.start_date
      %td
       = history.end_date
      %td
       = history.total_cost
      %td
       = history.rating

这将从历史数据中填充您的表格。
