jinja2

问题 Is there a way in Jinja2 to construct a variable name and then call it? I want to do something like this: {% for type in ('Students', 'Faculty', 'Groups') %} {% set import_name = 'latest_' + type|lower + '_import' %} {{ type }}: {{ import_name.created_at }} {% endfor %} I would expect the output to be something like this: Students: 5/26/2016 Faculty: 5/25/2016 Groups: 5/25/2016 I have the variables latest_students_import, latest_faculty_import, and latest_groups_import set in the template

问题 I am new to Flask and web applications in general. I have images that could be located in different locations: -directory1 -image1 -directory2 -subdirectory -image2 -directory3 -flask_app -app.py -static The purpose of the app is to dynamically provide access to the content in other directories which is not static and subject to change for each user.

问题 I'm working on a flask app and using flask-wtf to help manage my forms. There are 2 ways to register on my site - Either with or without an email token.

问题 I'm using GAE (in Python) to make a web app, but I have been bumping into some problems with inputting a form (name, class year, bio) into the datastore. This actually used to work before, but not anymore; I'm not too sure what event went wrong here. Here are my controller and template. The error I've been getting is: File "/base/data/home/apps/p~clubs-cs50/1.389022909265479577/main.py", line 136, in post identity=user.user_id(), AttributeError: 'function' object has no attribute 'user_id'

问题 How to use this solution https://stackoverflow.com/a/10067749/604240 in jinja 2 template? 回答1: I agree my question was due to lack of knowledge than problem. Eventually I figured it out how to achieve it. Basically I didn't know how to link loop from python code to query so it's available to Jinja2 template.

问题 I'm going through the tutorial for the Pyramid framework and I'm currently stuck at the one that teaches the use of Jinja2 as the templating engine.. It seems that when I run the test using nosetests , I get this odd ImportError stating that the name Environment couldn't be imported from the Jinja2 module.

问题 We're trying to come up with a way to use ansible facts within jinja2 For Loops. For example, I want to get all servers that belong to my memcached group as well as a group based on release (something like tag_release_dev or tag_release_prod ). When I try to use {{ tt_release }} within the For Loop it evaluates {{ tt_release }} rather than the value of the variable. Is there a way to use a variable within the loop definition? {% for host in groups["tag_function_mem"] | intersect(groups["tag
