问题 I pull a feed from rss and store the data in a appengine db. The rss feed content includes the entire html. So I have this python code: @app.route("/rssRead") def pullRss(): feedItem = db.getFeedItemByName(request.args.get('title',None), request.args.get('key',None)) return render_template("rss.html", data= Markup(feedItem.html).unescape()) And my html template looks like this: {% extends "layout.html" %} {% block body %} {{ data }} {% endblock %} So when I view the page I have the actual

问题 I'm using Jinja2 on a new project, but would like to use the django-socialregistration app, which relies on Django template tags. Jinja2 doesn't play nicely with template tags, so I'm wondering if there's a quick workaround? Template tags: {% load facebook_tags %} {% facebook_button %} {% facebook_js %} This previous question addresses the same topic for Mako, but I'm having trouble adapting it to work with Jinja2. The following is my attempt at an adaptation (non-working): {% from django

问题 I need to generate a random number between 1 and 50. Aparently the random filter needs a sequence. How can I create a list with numbers from 1 to 50 in Jinja? {{ [1,n,50]|random() }} 回答1: Jinja2 also includes the range function which returns a sequence of numbers from start to end - 1 , so you can use it with random: Your lucky number is: {{ range(1, 51) | random }} 来源： https://stackoverflow.com/questions/36683951/generate-random-number-with-jinja2

问题 Jinja2 converts all template variables into unicode before processing. Can anybody find a place where does this happen? The problem is that it assumes that strings are ascii , but we (at Roundup) are using utf-8 internally and our ORM (HyperDB) restores object properties to utf-8 automatically, and converting them all into unicode in every view just before passing to templates is too much legwork. 回答1: Answer from Armin: Unfortunately that is impossible. Jinja uses the default string coercion

问题 Is it possible to import a Python module into a Jinja template so I can use its functions? For example, I have a format.py file that contains methods for formatting dates and times. In a Jinja macro, can I do something like the following? {% from 'dates/format.py' import timesince %} {% macro time(mytime) %} <a title="{{ mytime }}">{{ timesince(mytime) }}</a> {% endmacro %} Because format.py is not a template, the code above gives me this error: UndefinedError: the template 'dates/format.py'

问题 I have a jinja2 template which I reuse for different Flask routes. All of these routes have a single required parameter and handle only GET requests, but some routes may have extra arguments. Is there a way to append extra arguments onto url_for() ? Something like url_for(my_custom_url, oid=oid, args=extra_args) which will render to (depending on the route endpoint): # route 'doit/<oid>' with arguments doit/123?name=bob&age=45 # route 'other/<oid>' without arguments other/123 My use case

问题 I have an ansible playbook in which one variable I am passing from the command. I am trying to append a windows folder path to it. One way I am able to find out is to add the path to another variable and then join the two variable. I would like to know if it is possible to avoid the variable and put the path like this: "{{ variable2 }} \build\dist\package\ui.msi" variable1 has value "d:\install" var_build_file_name is entered by the user variable2 is formed by combining variable1 and var

问题 I have a /consults page displaying a list of consults. My list loop looks like this: {% for consult in consults %} <tr> <td><a href="/consults/view-consult?key={{consult.key.urlsafe()}}">{{ consult.consult_date }}</a></td> <td>{{ consult.consult_time }}</td> <td>{{ consult.patient_first }}</td> <td>{{ consult.patient_last }}</td> <td><span class="badge badge-warning">{{ consult.consult_status }}</span></td> </tr> {%endfor%} So I'm using the url to send a Consult key to the individual page to
