I have been working on a search bar in django and I am close but having some issues rendering the results to the page.
Views.py
class SearchResultsView(ListView):
model = Project
template_name = 'search_results.html'
def get_queryset(self):
proj=self.request.GET.get('proj')
proj_list=Project.objects.filter(
Q(name__icontains=proj) | Q(projectTag__icontains=proj)
)
proj_list1=Project.objects.filter(
Q(department__icontains=proj)
)
proj_list2 = list(set(proj_list) & set(proj_list1))
return proj_list2
class SearchPageView(TemplateView):
template_name = 'searchbar.html'
search_results.html
{% extends 'main/base.html' %}
<html>
{%block content%}
<h1> Search Results </h1>
{% if proj %}
<ul>
{% for project in proj_list2%}
<li>
{{project.name}}, {{project.department}}, {{project.projectTag}}
</li>
{% endfor %}
</ul>
{% else %}
<h2>sorry, no results</h2>
{% endif %}
{%endblock%}
</html>
Whenever I search something that should definitely yield results, I get "sorry, no results."
Thank you. Please help me to understand my disconnect. The bigger aim for this is to then add different models to query from (i.e. not just search in projects, but also search by user).
You are checking the wrong variable. The collection of elements is object_list, not proj or proj_list2:
{% if object_list %}
<ul>
{% for project in object_list %}
<li>
{{project.name}}, {{project.department}}, {{project.projectTag}}
</li>
{% endfor %}
</ul>
{% else %}
<h2>sorry, no results</h2>
{% endif %}
The search is also quite odd, you only retrieve items if both the department and the name or the tag matches. We can simplify this to:
class SearchResultsView(ListView):
model = Project
template_name = 'search_results.html'
def get_queryset(self):
proj = self.request.GET.get('proj')
return =Project.objects.filter(
Q(name__icontains=proj) | Q(projectTag__icontains=proj),
department__icontains=proj
)
but it is odd that the department and the name for example should match. If you want to match any of the three, we can work with:
class SearchResultsView(ListView):
model = Project
template_name = 'search_results.html'
def get_queryset(self):
proj = self.request.GET.get('proj')
return =Project.objects.filter(
Q(name__icontains=proj) |
Q(projectTag__icontains=proj) |
Q(department__icontains=proj)
)

I want to get m2m data in my template through the views but failing to do so. The thing is that I'm able to show the data of m2m field looping it from template itself but it does slow down the website.
My Team apps Model looks like this:
class Team(models.Model):
title = models.CharField(max_length=255)
team_country = CountryField(max_length=200, blank=True, null=True)
members = models.ManyToManyField(User, related_name='teams')
created_by = models.ForeignKey(User, related_name='created_teams', on_delete=models.CASCADE)
Now in my tournament app I'm trying to get "members" of the team.
My Tournamet Views look like this:
def tournament_page(request, slug):
page = 'tournament_page'
user = request.user
tournament = Tournament.objects.get(slug=slug)
players = tournament.participants.select_related('user')
all_players = Profile.objects.select_related('user')
side_tourneys_ongoing = Tournament.objects.filter(state='Ongoing')[:10]
side_tourneys_upcoming = Tournament.objects.filter(state='Upcoming')[:10]
side_tourneys_completed = Tournament.objects.filter(state='Completed')[:10]
teams = Team.objects.select_related('created_by')
context = {
'page': page,
'tournament': tournament,
'side_tourneys_ongoing': side_tourneys_ongoing,
'side_tourneys_upcoming': side_tourneys_upcoming,
'side_tourneys_completed': side_tourneys_completed,
'teams': teams,
'players':players,
'all_players':all_players
}
Now I'm able to show the teams with their members in the template using for loop inside the template itself as:
Html template
<div class="grid-x">
{% for team in teams %}
{% for player in players %}
{% if team.id == player.active_team_id and team.game == tournament.game %}
<div class="wf-card event-team">
<div> {{team.title}} </div>
<div class="event-team-players">
{% for member in team.members.all %}
{{ member.username }}
{% endfor %}
</div>
</div>
{% endif %}
{% endfor %}
{% endfor %}
</div>
What I want is to use this piece of code
{% for member in team.members.all %}
{{ member.username }}
{% endfor %}
in my views since it causes the website to slow down and idk why.
What I tried in my views is:
all_teams = Team.objects.all()
members = all_teams.members.all()
and
members = Team.objects.all().prefetch_related('members')
First one throws an error:
'QuerySet' object has no attribute 'members'
Second one shows lots of blank records
Tried almost everything with search but none of them helped except using the code that I provided directly in the template itself.
Edited based on comments below. You should be able to do this more simply by prefetching team members.
views.py
def tournament_page(request, slug):
page = 'tournament_page'
user = request.user
tournament = Tournament.objects.get(slug=slug)
all_players = Profile.objects.select_related('user')
side_tourneys_ongoing = Tournament.objects.filter(state='Ongoing')[:10]
side_tourneys_upcoming = Tournament.objects.filter(state='Upcoming')[:10]
side_tourneys_completed = Tournament.objects.filter(state='Completed')[:10]
teams = Team.objects.select_related('created_by').prefetch_related('members')
template.html
<div class="grid-x">
{% for team in teams %}
{% if team.game == tournament.game %}
<div class="wf-card event-team">
<div> {{team.title}} </div>
<div class="event-team-players">
{% for member in team.members.all %}
{{ member.username }}
{% endfor %}
</div>
</div>
{% endif %}
{% endfor %}
</div>
models.py
class PostModel(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
date_time = models.DateTimeField(auto_now_add=True)
title = models.TextField(null=True)

def __str__(self):
return str(self.user)

I have to specifically set the timezone in setting.py, but I want to display the time according the user location.
Django has inbuilt functionality for handling timezones. Reading the documentation at Django Timezone Documentation should help you out. An example is provided there.
I'm making a site by using django. One of my models contains ImageField.
Files are saved in main_dir/media/images. I'd like to display specific images in templates but I can't achieve it. Instead of photo, I can see only default image icon which mean ( i guess ) that image is not found
settings.py
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
models
class Gallery(models.Model):
name = models.CharField(max_length=200)
author = models.ForeignKey(User, on_delete=models.CASCADE, default=None, null=True, blank=True)
date_posted = models.DateTimeField(auto_now_add = True)
def __str__(self):
return self.name
class Photo(models.Model):
gallery = models.ForeignKey(Gallery, on_delete=models.CASCADE, default=None, related_name='photos')
name = models.CharField(max_length=200)
description = models.TextField(blank=False)
image = models.ImageField(blank=True, upload_to='images')
views
def gallery(request, pk):
gallery_object = Gallery.objects.get(id=pk)
context = {'gallery':gallery_object}
return render(request, 'Gallery/gallery.html', context)
html
<!DOCTYPE html>
{% extends 'base.html' %}
{% block content %}
<h1>Gallery: {{ gallery.name }}</h1>
{% for photo in gallery.photos.all %}
<img src="{{photo.image.url}}">
<a>{{photo.image.url}}</a> #it's here only to check if path is correct
{% endfor %}
Go back to home page
{% endblock content %}
what should I change to display image correctly ?
you need to change the .get to .filter with the same condition to get multiple objects
because get will return 1 object only and you cant do the for loop in the template
There are a few things wrong. First of all, if you want to return multiple images then you have to use .filter() instead of .get() and if you are .get() instead of the filter then you don't have to loop over it as it is giving a single object. And the image is stored in Photos model and for that you will have to call that instead of gallery.
Here is how you can fix it:
For single object:
views function:
def gallery(request, pk):
gallery_object = Photos.objects.get(id=pk)
context = {'photo': photo_object}
return render(request, 'Gallery/gallery.html', context)
HTML template:
<!DOCTYPE html>
{% extends 'base.html' %}
{% block content %}
<h1>Gallery: {{ photo.name }}</h1>
<img src="{{photo.image.url}}">
<a>{{photo.image.url}}</a> #it's here only to check if path is correct
Go back to home page
{% endblock content %}
For returning multiple objects:
views function:
def gallery(request, pk):
gallery_object = Photos.objects.filter(#your query)
context = {'photos': photo_object}
return render(request, 'Gallery/gallery.html', context)
HTML:
<!DOCTYPE html>
{% extends 'base.html' %}
{% block content %}
{% for photo in photos %}
<h1>Gallery: {{ photo.name }}</h1>
<img src="{{photo.image.url}}">
<a>{{photo.image.url}}</a> #it's here only to check if path is correct
{% endfor %}
Go back to home page
{% endblock content %}
finally, i found an issue. I forgot about adding
urlpatterns+=static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)
to my urls.py file.
lmao
So i'm creating a to-do app. How do I get the html view to show the tasks? I tried to show the name of the tasks but it's blank. So far, it only shows the board name and the user who created it.
Here is my code so far:
Models.py
class Board(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
admin = models.ForeignKey(User, on_delete=models.CASCADE, related_name="Board")
name = models.CharField(max_length=200)
class Task(models.Model):
board = models.ForeignKey(Board, on_delete=models.CASCADE)
admin = models.ForeignKey(User, on_delete=models.CASCADE)
text = models.CharField(max_length=300)
complete = models.BooleanField(default=False)
assigned_to = models.CharField(max_length=30)
views.py
def board_post_detail(request, board_id):
obj = get_object_or_404(Board, id=board_id)
taskobj= Task.objects.filter(board=obj)
context = {"object": obj, "tasks": taskobj}
return render(request, 'boards/board_post_detail.html', context)
board_post_detail.html
{% block content %}
<h1>{{ object.name}}</h1>
<p> {{tasks.text}}<p>
<p>Created by {{object.admin.username }}</p>
{% endblock %}
I realise that I needed to use a for loop to iterate throught the tasks.
{% block content %}
<h1>{{ object.name}}</h>
<ul>
{% for task in tasks %}
<li>{{ task.text }} is assigned to {{ task.assigned_to }}</li>
{% endfor %}
</ul>
<p>Created by {{object.admin.username }}</p>
{% endblock %}
Here is my image model, that I tied to the model Product
class Image(models.Model):
name = models.CharField(blank=True,max_length=20)
product = models.ForeignKey(Product)
image = models.ImageField(blank=True,null=True)
def __str__(self):
return self.name
Here is the view that I am using to try and display the images
def category(request, category_id):
categories = Category.objects.all()
images = Image.objects.all()
products = Product.objects.all()
try:
category = Category.objects.get(id=category_id)
except Category.DoesNotExist:
category = None;
template = loader.get_template('index.html')
context = {
'category': category,
'categories': categories,
'images': images,
'products': products
}
return HttpResponse(template.render(context,request))
and here is the html
{% for image in images %}
<img src="{{ image.url }}">
{% endfor %}
I know this definitely wouldn't work,but atleast this code displays the page instead of an error so i have been using it, can anyone please point me in the right direction to dipslay each image associated with each product.
Thank you!
You can try this:
{% for product in products%}
<p> {{product.name}} </p>
{% for simage in product.image_set.all %}
{% if simage.image%}
<img src="{{ simage.image.url }}">
{% endif %}
{% endfor %}
{% endfor %}
