jinja2

问题 I have a Jinja2 template page which contains two separate {% for %} loops. If neither of these loops contain any items, I want the page to redirect. I'm trying to do something like this (pseudo-code): loop1 = loop.length (in first loop) loop2 = loop.length (in second loop) if loop1 + loop2 == 0: redirect # (outside both loops) Is this even possible? Is there a way to make the loop.length variables available outside their respective loops? 回答1: You can check your lists for truth, empty lists

问题 Using django, with jinja2 for rendering & babel for message extraction I have some js files that need to be internationalized. I haven't been able to figure out a syntax for extracting messages from them which would also let jinja2 render them. Either jinja2 has to learn to read an extractable syntax, or I have to extract from something jinja2 can render. (Or, do this another way entirely) Extracting If I mark messages in the js with gettext('message') It extracts just fine. Rendering But

问题 I've searched to no avail.. I guess my question is a bit unique. I have a DIV with some content in it, that content get's brought in currently by passing the object of a SQL query into the template. That works fine, but doesn't allow me to update the content every x seconds, without refreshing the entire page. Something I don't want to do. So I wanted to know I could force JQuery to reload my DIV element? Would this also reload the code in it? Because that would force my div to update.. Here

问题 I'm using Jinja2 to create html reports as a single html file. I would like to include the company logo inside the html file rather than link to it; in this way the logo is displayed even if the person reading the report is offline. Can this be automatically done using Jinja2? If not how can I embed a png image in the html manually? 回答1: look for a Base64 encoder on Google (e.g. http://www.opinionatedgeek.com/dotnet/tools/base64encode/). After that you can insert <img src="data:image/png

问题 I know this has been asked before, and I'm still pulling my hair out trying to figure this one out. I've tried pytz, dateutil, and now flask_moment. Still having problems converting a MySQL table datetime, which is UTC, to display in the jinja2 template as local time, specifically UTC - 05:00 (EST). My jinja2 for loop looks like this: {% for data in items %} ... <td>{{data.loggedInBy}}</td> <td>{{data.timeIn.strftime('%I:%M %p')}}</td> ... {% endfor %} I'm new to python/flask/jinja, so go

问题 This question already has answers here : Using Flask-WTForms, how do I style my form section of the html? (2 answers) Closed 3 years ago . I am following this tutorial http://flask.pocoo.org/docs/0.10/patterns/wtforms/ Here’s an example _formhelpers.html template with a macro: {% macro render_field(field) %} <dt>{{ field.label }} <dd>{{ field(**kwargs)|safe }} {% if field.errors %} <ul class=errors> {% for error in field.errors %} <li>{{ error }}</li> {% endfor %} </ul> {% endif %} </dd> {%
