How to make a loop in views.py in django

Question

I don't want to repeat Destination function again and again in separate variables. I tried to make different variables and equaled them to Destination() but it didn't work. How to make a loop in it so that I don't have to repeat it?

def index(request):
    dest1 = Destination()
    dest1.desc = 'Hello, How are you?'
    dest1.img = '01.jpg'

    dest2 = Destination()
    dest2.desc = 'Hello, HOw are you?'
    dest2.img = '02.jpg'

    dests1 = [dest1, dest2] # that was missing.

    context = {
       'dests1': dests1,
       'dests2': dests2,
}

return render(request, 'index.html',context)

Will anyone answer my question?

inside your def index(request) function make a loop upto the number of time you needed Destination() object and save data in a list, from that list you can retrieve data later. You can also make list of images, descriptions to things more easily

numberOfDestinationNeeded = 4 # change this number according to your need
destList = []
for i in range(numberOfDestinationNeeded):
    destObj = Destination()
    destObj.desc = "dfsfs"
    destObj.img = '02.jpg'
    destList.append(destObj)

You can do something like this.

no_of_destinations = 4 #Some number.
context = {}
for index in range(1, no_of_destinations+1):
    dest = Destination()
    dest.desc = 'How are you?'
    dest.img = '0{}.jpg'.format(index)
    context['dest{}'.format(index)] = dest

return render(request, 'index.html',context)

Then its a different issue. Check if image is present or not in your static directory.
