Image is not editing after click on update button - html

I am going through a Django tutorial and My blog post image is not editing for edit post in my blog app. I use Django==3.1.2.
views.py
def edit_post(request, post_id):
post = BlogPost.objects.get(id=post_id)
if request.method != 'POST':
form = UpdatePost(request.POST or None, request.FILES or None, instance=post)
else:
form = UpdatePost(instance=post, data=request.POST)
if form.is_valid():
form.save()
return redirect('mains:posts')
context = {'post':post,'form':form}
return render(request, 'mains/edit_post.html', context)
forms.py
class UpdatePost(forms.ModelForm):
class Meta:
model = BlogPost
fields = ['blog_post_title','blog_description','image']
edit_post.html
{% block content %}
<div class="container">
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<button type="submit">Save Changes</button>
</form>
</div>
{% endblock content %}
The Problem
I am trying to edit my post in my blog app, Everything is working fine ( Blog title and Blog description is changing ) - when i change image it returns ( redirect ) fine BUT image not changing.
I am stuck with this problem and have no idea what is wrong.
What have i tried.
1). When i first create the view then i didn't add (request.POST or None, request.FILES or None), BUT
when i notice that, this may be effecting from editing then i added and it still not editing the image.
2). I have also changed template before BUT nothing works.
3). I have also changed form before BUT nothing workes.
Help me in this. I will really appreciate your Help. Thank you in advance !!

try this...
def edit_post(request, post_id):
post = BlogPost.objects.get(id=post_id)
if request.method != 'POST':
form = UpdatePost(request.POST or None, request.FILES or None, instance=post)
else:
form = UpdatePost(instance=post, data=request.POST, files=request.FILES)
if form.is_valid():
form.save()
return redirect('mains:posts')
context = {'post':post,'form':form}
return render(request, 'mains/edit_post.html', context)

How Do I Properly Submit Two Forms Within One HTML Structure?

I am trying to submit a create view with two forms. The code below works fine if everything is filled out and the form submitted. However if fields are omitted in form2...the form submission fails and the field that was filled out for "form"..."name"....gets reset. I've read you can do multiple forms and I've largely got this working...I just need to figure out how to incorporate form2 into the if_valid().... Here's my view...
def tasklist_detail_view(request, id):
context = {}
context["tasklist"] = TaskList.objects.get(id=id)
context["tasks"] = Task.objects.filter(task_list=id).all()
obj = get_object_or_404(TaskList, id=id)
form = UpdateTaskListForm(request.POST or None, instance=obj)
form2 = TaskForm(request.POST or None)
context["task_list_id"] = id
if form.is_valid():
form.save()
return HttpResponseRedirect(reverse("MyTaskLists:my_task_list_main_menu"))
context["form"] = form
context["form2"] = form2
return render(request, "my_task_list_tasklist_detail.html", context)
My HTML...
<form method="POST" enctype="multipart/form-data" id="forms">
{% csrf_token %}
{{ form.name }}
{% include "my_task_list_task_create_form1.html" with tasklist=tasklist %}
<button type="submit" class="button66" name="status" value="Submitted">Submit</button>
</form>
And then in my include HTML...
<div id="task-list-form" hx-target="this" hx-swap="outerHTML">
<button class="button35" hx-post="{% url 'MyTaskLists:task-create' id=task_list_id %}">Save</button>
{{ form2 }}
I did try to do something like....
if form.is_valid() and form2.is_valid():
form.save()
return HttpResponseRedirect(reverse("MyTaskLists:my_task_list_main_menu"))
But then nothing happens...the forms are not accepted at all even if the fields are filled out properly....From what I've read I understand the POST is being applied to both forms....if one is not filled out properly that is why the other errors out? I just can't quite figure out how to process them both properly.
Thanks in advance for any thoughts.
If you want the two forms to behave like one form, and save two objects only if both forms are valid, then the logic is
if form.is_valid() and form2.is_valid():
form.save()
form2.save()
return HttpResponseRedirect(reverse("MyTaskLists:my_task_list_main_menu"))
context["form"] = form
context["form2"] = form2
return render(request, "my_task_list_tasklist_detail.html", context)
If there is any field with the same name in form and form2 you need to use a prefix to remove the ambiguity.
form = UpdateTaskListForm(request.POST or None, instance=obj, prefix='form1')
form2 = TaskForm(request.POST or None, prefix='form2')

how to pass value from html to view in django?

I have made this HTML code:
<h3>your major is {{user.userprofile.major}}</h3>
This will correctly show the major on the webpage, but I want to use this string to get something from another table in view.
How would I pass this string to view?
edit:
Here is my view.py
def dashboardView(request):
obj = BooksFile.objects.all()
query = BooksFile.objects.filter(book_major='cs)
return render(request, 'dashboard.html', {'books': obj, 'major': query})
def registerView(request):
if request.method == "POST":
form = UserCreationForm(request.POST)
profile_form = UserProfileForm(request.POST)
if form.is_valid() and profile_form.is_valid():
user = form.save()
profile = profile_form.save(commit=False)
profile.user = user
profile.save()
return redirect('login_url')
else:
form = UserCreationForm()
profile_form = UserProfileForm()
context = {'form': form, 'profile_form': profile_form}
return render(request, 'registration/register.html', context)
here is my template:
{% extends 'index.html' %}
{% block content %}
<h1>Welcome, {{user.username}}</h1>
<h2>Your major is {{user.userprofile.major}}</h2>
{% for book in books %}
<h3>Your book name is {{book.book_name}}</h3>
{% endfor %}
{% endblock %}
I am trying to show the book names from the booksfile table by corresponding major that user has. Right its showing the books that has "cs" attribute because I manually put "cs" in the get function in view. I am trying to send the major string from template to view, so that I can put what ever the user's major is in the get function. Or is there any other way to do it.
You need to use a form in your template and submit it to call your view. i.e.
<form action="your_view_url" method="POST">
<input type="text" name="major" value="{{user.userprofile.major}}"/>
<input type="submit"/>
</form>
an then in your view you access that with:
if request.POST:
major = request.POST.get('major')
As per documentation: https://docs.djangoproject.com/en/2.2/topics/forms/
First of all you have to get the value of model with help of queryset, and put it in the dictionary and then pass it with the template.
In views:
def get(self, request):
queryset = Model_name.objects.all()
ctx = {
'queryset': queryset,
}
return render(request, 'page_name(or template_name).html', ctx)
in template:
<form action="{%url'(your_view_name without brackets)'%}" method="POST">
{% for data in queryset%}
<span class="username">{{data.name(field of your model)}} .
</span>
<span class="email">{{data.email(field of your model)}} .
</span>
{% endfor%}
</form>

Django how to adding comments option on a post

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.

how to get the data from view to templates?

i'm trying to get the data from my views.py to the html page.
if the views.py code is this
def VerifiedBySuperuser(request):
if request.method == 'POST':
vbs = MaanyaIT_EXAM48_ManageQuestionBank()
vbs.QuestionID = MaanyaIT_EXAM48_ManageQuestionBank.objects.get(QuestionID=request.POST.get(QuestionID, None))
vbs.QuestionInEnglishLang = request.POST.get('QuestionInEnglishLang', None)
vbs.save()
else:
return render(request, 'exam48app/verifiedbysuperuser.html')
then what shoud the code of html page to view my all data to the tamplates..
this is my html page
<form class="from-horizontal" method="post" enctype="multipart/form-data">
{% csrf_token %}
<div class="post-entry">
{{ MaanyaIT_EXAM48_ManageQuestionBank.QuestionInEnglishLang }}
</div>
</form>
now what should i do?
From your comment, you need to know How to write/render the data from view to html template
I will demonstrate a simple example for you,
Assuming you have a view as below,
def VerifiedBySuperuser(request):
if request.method == 'GET':
context = {
"T_Name": "My Name",
"T_Age": 50,
"T_Phone": 1478523699
}
return render(request, 'verifiedbysuperuser.html', context=context)
and a HTML template as follows,
<!DOCTYPE>
<html>
<body>
Name : {{ T_Name }}<br>
Age : {{ T_Age }}<br>
Phone : {{ T_Phone }}<br>
</body>
</html>
When you access your view, you will get a response like this,
In your case, you can pass as many attributes to template as dict (shown in my example) and in template/html keys of context (that is T_Name,T_Name etct) becomes variable. So you can directly use them in HTML inside the twin braces ({{ variable_name }})
As far as I knew, this is the general procedure for template rendering/ html rendering
UPDATE-1
def VerifiedBySuperuser(request):
if request.method == 'POST':
obj = MyModel.objects.get(id=some_id)
other_data = [1,2,3,4,] # some specific data
context = {
"post_data": request.data,
"object_instance": obj,
"some_other_data": other_data
}
return render(request, 'verifiedbysuperuser.html', context=context)

django open specific html tab in response

I have a django view which render a html page in response to a POST request. I want to open a specific tab in that html page when rendered.
My view:
def internalManifest(request):
form = forms.TrackingID(request.POST or None)
if request.method == 'POST':
tracking_id = request.POST.get('tid')
messages.warning(request, 'Tracking Id Already Scanned')
return render(request, 'orders/order.html')
I want like:
return render(request, 'orders/order.html#demo-lft-tab-5')
How to do that?
EDIT: I know i can set the tag active in <div class=""... but that will make the tab active in all the redirects. I want to set it as active for this particular method.
You need to pass the active tab to the template context, for example:
render(request, 'orders/order.html', {'active_tab':'demo-lft-tab-5'})
Then in your template, check the active_tab variable, and add the "active" css to the correct tab. For example:
<div class ="demo-lft-tab-5 {% if active_tab == 'demo-lft-tab-5' %} active{% endif %}">
