从数据库中替换句子中的单词(Python/Django)
我的句子结构是这样的: 从$Duration%开始,$名词$将是$形容词$ 我需要一个视图来检查“$$”中的单词,并用从SQL文件导入的数据库中的随机单词替换它们 以下是模型/sql文件:从数据库中替换句子中的单词(Python/Django),python,sql,database,django,views,Python,Sql,Database,Django,Views,我的句子结构是这样的: 从$Duration%开始,$名词$将是$形容词$ 我需要一个视图来检查“$$”中的单词,并用从SQL文件导入的数据库中的随机单词替换它们 以下是模型/sql文件: from django.db import models from django.utils import timezone class Type(models.Model): type = models.CharField(max_length=50) value = models.Cha

及
我开始写这个观点。需要一些帮助:
from quest.models import Word, Type, Score, Question, Meta
from django.utils import timezone
def question(request):
sentence = Question.objects.all()
find_words = re.findall(r"\w+%0-9a-zA-Z%", sentence.question)
如果您愿意更改符号,您有两个选择:
其余的部分是从数据库中提取并选择单词at,这是最简单的部分。是否固定了
$…$
符号?否。我只是使用了“$”作为标记。可以替换。是的,我可以更改符号。行“t=Template('从{Duration}开始,{{Noun}}}将是{{形容词}}'”,您是否假设问题保持不变?我也想为任何问题生成它。您可以将任何您喜欢的内容传递给模板
构造函数。我将如何更改>>c=Context(dict(Duration='24小时',名词='Coffee Maker',形容词='Break'))所以它会生成随机单词?你有没有花点时间看看答案最后一句中的链接?
from quest.models import Word, Type, Score, Question, Meta
from django.utils import timezone
def question(request):
sentence = Question.objects.all()
find_words = re.findall(r"\w+%0-9a-zA-Z%", sentence.question)
>>> 'Starting in {Duration}, the {Noun} will be {Adjective}'.format(Duration='24 hours', Noun='Coffee Maker', Adjective='broken')
'Starting in 24 hours, the Coffee Maker will be broken'
>>> 'Starting in %(Duration)s, the %(Noun)s will be %(Adjective)s' % dict(Duration='24 hours', Noun='Coffee Maker', Adjective='broken')
'Starting in 24 hours, the Coffee Maker will be broken'
>>> from django.template import Context, Template
>>> t = Template('Starting in {{Duration}}, the {{Noun}} will be {{Adjective}}')
>>> c = Context(dict(Duration='24 hours', Noun='Coffee Maker', Adjective='broken'))
>>> t.render(c)
u'Starting in 24 hours, the Coffee Maker will be broken'
