问题 I added a facebook button to my page by copying/pasting the code they supply on their website. It looks like this: "http://www.facebook.com/dialog/feed?app_id={{fbapp_id}}&link={{link_url}}&message={{share_message|urlencode}}&display=popup&redirect_uri={{link_url}} As you can see, it's got the {} in there that Jinja looks for. However, being that I don't want any of the above code replaced with anything, is there something I can add into my template which tells Jinja to ignore everything

问题 {% if bCat2 == True %} <div>True</div> {% else %} <div>False</div> Returns <div>False</div> even when bCat2 is True . Thanks, Andrew 回答1: This part of documentation can help you: The special constants true, false and none are indeed lowercase. Because that caused confusion in the past, when writing True expands to an undefined variable that is considered false, all three of them can be written in title case too (True, False, and None). However for consistency (all Jinja identifiers are

问题 With regular python, I could get getattr(object, att) but in Jinja2, I get: jinja2.exceptions.UndefinedError jinja2.exceptions.UndefinedError: 'getattr' is undefined How can I use it? 回答1: Jinja2 is not Python . It uses a Python-like syntax, but does not define the same built-in functions. Use subscription syntax instead; you can use attribute and subscription access interchangeably in Jinja2: {{ object[att] }} or you can use the attr() filter: {{ object|attr(att) }} From the Variables

问题 In a Jinja2 template I want to display the last login: Last Login: {{ user.last_seen }} last_seen is supposed to be a datetime object in sqlite. It always gives me something like: 2014-07-27 23:09:36.467761 How do I remove the microseconds part of that when displaying on my template? 回答1: You are using the default string formatting of a datetime object, which is essentially the same as calling datetime.isoformat(' '), a format that includes the microseconds component. If you want a different

问题 When I try to run some commands on nxos devices, the output has a white space at the end. I have to compare the output to an existing variable list.
