python - 变色龙模板循环

Question

我尝试使用变色龙创建模板。这是代码片段。

调用模块runtemp.py:

delete_list=[]
delete={'Name':'aaa','Sirname':'bbb','Friends':['ccc','ddd','eee']}
delete_list.append(delete)
templates = PageTemplateLoader(os.path.join(path, "templates"))
template = templates["delete_user.pt"]
print template(tdelete_list=delete_list)

模板文件delete_list.pt:

 <?xml version="1.0" encoding="UTF-8"?>
 <Delete>
   <DeleteRequest>

       <DeleteItems tal:repeat="deletions tdelete_list">

           <Deleteuser tal:repeat="delete repeat.deletions" >

                <Name tal:content="repeat.delete.Name"></Name>
                <Sirname tal:content="repeat.delete.Sirname"></Sirname>
                 <Friends>
                      <Friend tal:repeat="friend repeat.delete.Friends">
                               <Value tal:content="friend"></Value>
                       </Friend>
                 </Friends>

           </Deleteuser>

     <DeleteItems>

    </DeleteRequest>

 </Delete>

我得到的输出:

 <Delete>
        <DeleteRequest>

           <DeleteItems>



           </DeleteItems>
  </DeleteRequest>
 </Delete>

我的问题是中间标签没有被打印；怎么了？

线路<DeleteItems tal:repeat="deletions tdelete_list">表示循环tdelete_list并将每个元素放入变量 deletions 中.

因此，您的内部循环只需要循环 deletions ; repeat.此处未使用前缀:

<Deleteuser tal:repeat="delete deletions" >

    <Name tal:content="delete.Name"></Name>
    <Sirname tal:content="delete.Sirname"></Sirname>
     <Friends>
          <Friend tal:repeat="friend delete.Friends">
                   <Value tal:content="friend"></Value>
           </Friend>
     </Friends>

</Deleteuser>

repeat.deletions变量实际上仅用于存储循环元数据；当前计数，first和last标志，odd和even旗帜等
