Re: HOW TO OUTPUT DATA GOT FROM combined queryset IN DJANGO TEMPLATE (html file) ?
Thanks it worked but I would like to ask you, why did you use " game" in
{%for game in combined_list %} ? En what is the role of 'game'

Re: HOW TO OUTPUT DATA GOT FROM combined queryset IN DJANGO TEMPLATE (html file) ?
1.
In the windows_games view in others/views.py, you are using the filter()
method on the Action and Adventure models to get the action and adventure
games that have the 'os' field set to 'windows'. Then you are using the
itertools.chain() function to combine the two querysets into a single list,
and storing that list in the variable combined_list. The context variable
is not created correctly, it should be context = {'combined_list':
combined_list}
2.
In the template others/os/windows_game.html, to output the results of
the combined_list you should use a for loop to iterate over the list and
display each item. Also, it seems that you are trying to access the
game_pic attribute of the objects in the combined_list, but the models you
have defined (Action and Adventure) do not have a field called game_pic
3.
{% for game in combined_list %} {{
game.name }} {% endfor %}
4.
It would be a good idea to add a __str__ method to the models in order
to return the name of the game, and also to add a field game_pic if you
want to display the image of the game.
class Action(models.Model): name=models.Charfield() os=
models.Charfield(choices=OS) game_pic = models.ImageField(upload_to=
'action_game_pic/') def __str__(self): return

HOW TO OUTPUT DATA GOT FROM combined queryset IN DJANGO TEMPLATE (html file) ?
Hey! Am having a problem. And l request for your Help.
Am having 3 apps in Django project
- action
- adventure
- others
#action/ models.py
class Action(models.Model):
name=models.Charfield()
os= models.Charfield( choices=OS)
#adventure/models.py
class Adventure(models.Model):
name=models.Charfield()
os= models.Charfield( choices=OS)
#Others/views.py
from itertools import chain
from action.models import Action
from adventure.models import Adventure
def windows_games(request):
win_action = Action.objects.filter(os='windows')
win_adventure = Adventure.objects.filter(os='windows')
combined_list = list(chain(win_action,win_adventure))
context = ['combined_list':combined_list,]
return render(request, 'others/os/windows_game.html' , context)
#others/os/windows_game.html
.
{{combined_list.name}}
.
1). I need to correct me in #others/ views.py if there is any mistake done.
2). I would like to know how to know how to write the tag that outputs the
results in #others/os/windows_game.html because I tried that but outputs
nothing.
And l would like to be in form of,
#{{combined_list.game_pic}}, etc
Please help me.
