我的Django根目录中有两个日志文件,分别为apache.error.log
和django.log
。在我的app/static
文件夹中,我有HTML文件mylog.html
。现在,我想在该HTML页面中查看那些日志文件。
这可能吗?我想查看两个文件的最后20行。基本上类似于tail -f
,但是在浏览器内部,这样我可以始终打开一个选项卡进行调试。
最佳答案
如果您使用的是基于类的 View :
class LogTemplateView(TemplateView):
template_name = "mylog.html"
apache_log_file = "apache.error.log"
django_log_file = "django.log"
def get_context_data(self, **kwargs):
"""
This has been overriden to give the template access to the log files.
i.e. {{ apache_log_file }} and {{ django_log_file }}
"""
context = super(LogTemplateView, self).get_context_data(**kwargs)
context["apache_log_file"] = self.tail(open(self.apache_log_file, "r"), 20)
context["django_log_file"] = self.tail(open(self.django_log_file, "r"), 20)
return context

def tail(f, n, offset=None):
"""Reads a n lines from f with an offset of offset lines. The return
value is a tuple in the form ``(lines, has_more)`` where `has_more` is
an indicator that is `True` if there are more lines in the file.
"""
avg_line_length = 74
to_read = n + (offset or 0)
while 1:
try:
f.seek(-(avg_line_length * to_read), 2)
except IOError:
# woops. apparently file is smaller than what we want
# to step back, go to the beginning instead
f.seek(0)
pos = f.tell()
lines = f.read().splitlines()
if len(lines) >= to_read or pos == 0:
return lines[-to_read:offset and -offset or None], \
len(lines) > to_read or pos > 0
avg_line_length *= 1.3
