在Rally中替换模板故事的字符串

Question

我可以用Python代码成功地获取用户故事信息；但是，我希望替换位于details和user story name中的特定字符串。例如，字符串可以是$projectName，我想用用户输入的值替换它。你知道吗

有没有什么东西可以帮助我们编写代码，或者有一个有效的例子？我被卡住了，因为这不一定是一个要编辑的文件，层次结构输出也为我创建了一个块来开发一些有用的东西。你知道吗

以下是我提取数据的代码：

#!/usr/bin/env python
import sys
from pyral import Rally, rallyWorkset

options = [arg for arg in sys.argv[1:] if arg.startswith('--')]
args    = [arg for arg in sys.argv[1:] if arg not in options]
server, username, password, apikey, workspace, project = rallyWorkset(options)
if apikey:
        rally = Rally(server, apikey=apikey, workspace=workspace, project=project)
else:
        rally = Rally(server, username=username, password=password, workspace=workspace, project=project)
response = rally.get ('UserStory', fetch=True, query='Name contains "$projecttest"')
for story1 in response:
    print story1.details()

---

这是我得到的输出，当然是擦洗过的：

===============================================================

因此，使用PyRal，我必须向这个代码获取的每个用户故事发送一个更新，只在包含字符串的行上发送；然而，我必须以某种方式存储每个FormattedID:和关联的Name:字段以进行更新，这就是我被困在的地方，关于如何实际存储它以便可以迭代和更新它。你知道吗

Answer 1

您可以使用模板字符串来做您想做的事情，使用env变量来限定模板标记：

from string import Template
s = Template('this is $projectName')
s.substitute(projectName='THE_PROJECT')

结果：

'this is THE_PROJECT'

https://docs.python.org/3/library/string.html

另一种方法是，如果将projectName用大括号括起来，则使用format：

s = 'this is {projectName}'
print(s.format(projectName='THE_PROJECT'))
