I have been hacking away at this project for many hours now and just cannot figure out how to create a simple file upload app. I have looked at all the tutorials but none quite apply to my situation and i just cant get the code right. I know the code I have at this point wont run but I was hoping somone might be able to push me in the right direction with what I have. I know its not great but Im getting frustrated and I hope someone could help especially with my views.py Thank you so much. Thank you in advance!

i am stuck with it pls someone help me out
the solution for this is simple , thanks to shivendra-pratap-kushwaha for documentation link - docs.djangoproject.com/en/3.2/topics/http/file-uploads this was really helpfull
just need to specify request.FILES['file'] instead of request.FILES
So the title kind of says it all. I have a form based on a model. The goal is to have the specific data entered, user presses submit, data gets saved to a Postgresql DB, user sees complete.html. However this is not the case. I can either get the data to save without changing pages, or the page will change but the data will not submit. I have put details on the specifics of I tried below.

The Problem
I'm trying to make a project, where you can make topics, that can be private or public to unauthenticated users. In every topic, you can then make several entries, applying to that topic. Now I'm trying to make a checkbox in my new_topic.html, where if you check it, it evaluates to True, if not, to False. But I'm having trouble with making the checkbox evaluate to True, when I check it. And for some reason, there is two checkbuttons in the page that applies to new_topic.html; one with a label, and one with just a box.
What I've tried
I've tried recreating the db.sqlite3 database. But that didn't work.
I've tried using request.POST.get('public', False) in my new_topic() function, when saving the new_topic variable.ยจ
The Code
My learning_logs/models.py looks like this:
from django.db import models
from django.contrib.auth.models import User
class Topic(models.Model):
"""A topic the user is learning about."""
text = models.CharField(max_length=200)
date_added = models.DateTimeField(auto_now_add=True)
public = models.BooleanField(default=False)
owner = models.ForeignKey(User, on_delete=models.CASCADE)
def __str__(self):
"""Return a string representation of the model."""
return self.text
class Entry(models.Model):
"""Something specific learned about a topic."""
topic = models.ForeignKey(Topic, on_delete=models.CASCADE)
text = models.TextField()
date_added = models.DateTimeField(auto_now_add=True)
class Meta:
verbose_name_plural = 'entries'
def __str__(self):
"""Return a string representation of the model."""
# Add an ellipsis ONLY if the entry,
# is more than 50 characters long.
if self.text > self.text[:50]:
return self.text[:50] + "..."
elif self.text <= self.text[:50]:
return self.text[:50]
My learning_logs\views.py looks like this:

I just can't seem to fix this error. Thanks in advance! Any help is appreciated.
You have:
<input class="form-check-input" type="checkbox" value=True id="public">
<label class="form-check-label" for="public">
Make it public?
</label>
</input> # <<< this closing tag is wrong
correct input tag :
<input class="form-check-input" type="checkbox" value=True id="public" />
So you'll have:
<label class="form-check-label" for="public">
Make it public?
</label>
<input class="form-check-input" type="checkbox" value=True id="public" />
I am developing a blog which i want to add comment form option to it, i have added the form to the same page directly under the article, i want that went a user comment it should redirect to the same page with the article but i keep getting and error
here is my code
view
def comment(request, article_id):
try:
article = Article.objects.get(pk=article_id)
if request.method == 'POST':
form = CommentForm(request.POST)
if form.is_valid():
comment = form.cleaned_data['comment']
article.comments_set.create(comment=comment)
#messages.infos(request,comment)
return redirect('blog:_article')
#else:
#pass
#form = CommentForm()
#context['form'] = form
#return render(request,'blog/comment.html', context)
except Exception as e:
#wriet error to file
return render(request,'blog/404.html')
urls
from django.urls import path
from . import views
app_name = 'blog'
urlpatterns = [
path('', views.index, name='index'),
path('<int:article_id>/article', views._article, name='_article'),
path('<int:article_id>/comment', views.comment, name='comment'),
]
models
class Comments(models.Model):
comment = models.TextField()
date = models.DateTimeField(default=timezone.now)
article = models.ForeignKey(Article, on_delete=models.CASCADE)
def __str__(self):
return self.comment
form
<form method="post" action="{% url 'blog:comment' article.id %}">
{% csrf_token %}
{% for field in form %}
{{ field.label_tag }}
{% render_field field class="form-control is-valid" rows="4" %}
{% endfor %}<br>
<button class="btn btn-success">Post</button>
</form>
I finally did it by adding the code to handle the comment in the same view that renders the articles this is my code
def _article(request, article_id):
try:
article = Article.objects.get(pk=article_id)
related_articles = Article.objects.filter(tags=article.tags).exclude(pk=article.pk)[:4]
context['article'] = article
context['related_articles'] = related_articles
context['form'] = CommentForm()
if request.method == 'POST':
form = CommentForm(request.POST)
if form.is_valid():
comment = form.cleaned_data['comment']
article.comments_set.create(comment=comment)
return render(request,'blog/article.html', context)
except Exception as e:
#write error to file
return render(request,'blog/404.html')
If you don't want the page to redirect to another page or update the page, you should use AJAX (https://www.w3schools.com/jquery/jquery_ajax_get_post.asp) in this case. Your form will hit the url in the action by changing your page to that url so you have to handle the redirecting and rendering in your commenting view to come back to same page if you don't wanna do this dynamically.
The form field (text area) is not showing in my django template. I can figure out where the problem is.
Views.py
class Profile(View):
"""User Profile page reachable from /user/<username> URL"""
def get(self, request, username):
params = dict()
user = User.objects.get(username=username)
tweets = Tweet.objects.filter(user=user)
params["tweets"] = tweets
params["user"] = user
return render(request, 'profile.html', params)
class PostTweet(View):
"""Tweet Post form available on page /user/<username> URL"""
def post(self, request, username):
if request.method == 'GET':
form = TweettForm()
else:
form = TweetForm(self.request.POST)
if form.is_valid():
user = User.objects.get(username=username)
tweet = Tweet(text=form.cleaned_data['text'], user=user, country=form.cleaned_data['country'])
tweet.save()
words = form.cleaned_data['text'].split(" ")
for word in words:
if word[0] == "#":
hashtag, created = HashTag.objects.get_or_create(name=word[1:])
hashtag.tweet.add(tweet)
return HttpResponseRedirect('/user/'+username)
return render(request, 'profile.html', {'form': form})
forms.py
from django import forms
class TweetForm(forms.Form):
text = forms.CharField(widget=forms.Textarea(attrs={'rows': 1, 'cols':85}), max_length=160)
country = forms.CharField(widget=forms.HiddenInput())

{{ form.text }}
</div>
{{ form.country.as_hidden }}
<div>
<input type="submit" value="post">

</form>
</div>
urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
from tweets.views import Index, Profile, PostTweet
admin.autodiscover()
urlpatterns = patterns('',
url(r'^$', Index.as_view()),
url(r'^user/(\w+)/$', Profile.as_view()),
url(r'^admin/', include(admin.site.urls)),
url(r'^user/(\w+)/post/$', PostTweet.as_view())
)
Only the submit (post) button shows on the on when rendered in the browser. The text are is not there
You get nothing since you are not passing the form to the template. Write get function in PostTweet view and include form = TweetForm() in it as a param passed to the template.
