问题 I need a global variable that I can call from the templates. I edited app_globals.py in lib directory to declare PATH_TO_IMAGES like this class Globals(object): """Container for objects available throughout the life of the application. One instance of Globals is created during application initialization and is available during requests via the 'app_globals' variable. """ PATH_TO_IMAGES = "" def __init__(self): """Do nothing, by default.""" pass Now I can call from any template the image path

问题 Does anyone know if is there any way to create javascrit templates in Genshi? I mean, I need a .js file where I can use directives like <py:for> and so. Any idea? Thanks! 回答1: You can write it directly in html like this: <script type="text/javascript"> <py:if test="func1"> /*&lt;![CDATA[*/ function func1() { } /*]]&gt;*/ </py:if> </script> note: code inside CDATA will be right escaped, so you can use '>','<' as usual. 来源： https://stackoverflow.com/questions/3201343/javascript-templates

Why a single textarea messes following tags in xhtml? 回答1: Because you are, presumably, serving your XHTML with a text/html

Genshi - how to print out all variables in scope

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-11 00:42:56
问题 Quite simply I'd like to print out all variables that are in scope in my genshi template, as a debugging and discovery measure. Is there a way to do it? 回答1: The standard Python function locals() (which returns a dict) works for me.

问题 I'm trying to output the content of a comment with genshi, but I can't figure out how to transform the newlines into HTML paragraphs. Here's a test case of what it should look like: input: 'foo\n\n\n\n\nbar\nbaz' output: <p>foo</p><p>bar</p><p>baz</p> I've looked everywhere for this function.

I have tried to carefully construct some sample code for __new__ and __init__ that has no explanation I can find. The basic parameters: There is a base class called NotMine as it comes from another library (I'll disclose at the end, not important here) That class has an __init__ method that in turn calls a _parse method I need to override the _parse method in subclasses which subclass I'm creating is not known until invocation I know there are factory design methods but I cannot use them
