У меня есть сервер, написанный на django, и я хочу показать некоторый график, используя dygraph на шаблоне.Я написал одно представление и связанный с ним URL, а также передал некоторые переменные через контекст в шаблон.Используя эти переменные контекста, я хочу показать график.Но проблема в том, что график не отображается, и в URL-адресах наблюдается странное поведение.Ниже я публикую шаблон, URL-адрес и код просмотра.
@login_required
def profile(request, mid):
user = request.user
context = {}
delta_T = 1000
data = subprocess.check_output("tail -n {0} {1}".format(
delta_T, filename
),
shell=True)
data = data.split("\n".encode())
heatcsv = ""
fancsv = ""
tempcsv = ""
plot = []
for t in range(len(data)):
line = data[t].decode("utf-8")
entry = line.strip().split(" ")
try:
plot.append([int(float(i)) for i in entry[0:-1] \
+ [float(entry[-1])]])
heatcsv += "{0},{1}".format(t+1, entry[1])
fancsv += "{0},{1}".format(t+1,entry[2])
tempcsv += "{0},{1}".format(t+1, entry[3])
except:
continue
plot = zip(*plot)
context["mid"] = mid
context["delta_T"] = delta_T
context["heat"] = heatcsv
context["fan"] = fancsv
context["temp"] = tempcsv
return render(request,"dashboard/profile.html",context)

Я также включаю выводв терминале, когда я посещаю вышеуказанный URL.Я не могу понять, что именно не так в моем коде.Может кто-то указать, где ошибка.

Я думаю, что django добавляет все показания в URL, а не показывает его в шаблоне в виде графика..
