Django edit view does not show - django

Question

I am new to Django.
My app allows a user to create a project by providing a title and a body content, delete it and update it.
Now, I am creating and edit/update view for my app but it is not showing up in my html page.
urls.py
from django.urls import path, include
from . import views
urlpatterns = [
path('allprojects', views.allprojects, name='allprojects'),
path('createproject', views.createproject, name='createproject'),
path('<int:project_id>', views.projectdetail, name='projectdetail'),
path('<int:project_id>/editproject', views.editproject, name='editproject'),
]
projects/views.py
#login_required
def editproject(request, project_id):
if request.method == 'POST':
if request.POST['title'] and request.POST['content']:
project = get_object_or_404(Project, pk=project_id)
project.title = request.POST['title']
project.content = request.POST['content']
project.developer = request.user
project.save()
return redirect('/projects/' + str(project.id))
else:
return render(request, 'projects/editproject.html', {'error':'All fields are required.'})
else:
return render(request, 'projects/allprojects.html')
projects/templates/projects/editproject.html
{% extends 'base.html' %}
{% block title %}Edit Project{% endblock %}
{% block content %}
<div class="container">
<div class="row">
<div class="mt-4 offset-md-3 col-md-6">
<h2>Create a new project</h2>
<form method="post">
{% csrf_token %}
<div class="form-group">
<label for="exampleFormControlTextarea1">Title of the project</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="1" name="title"></textarea>
</div>
<div class="form-group">
<label for="exampleFormControlTextarea1">Brief description of this project</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="5" name="content"></textarea>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
</div>
</div>
</div>
{% endblock %}
PROBLEM
When I go to a urls such as http://localhost:8000/projects/2/editproject there is not the update form I want, the page exists but it contains nothing

Answer 1

You have to pass the project = get_object_or_404(Project, pk=project_id) in the dictionary in order to get the value in template.
Change your view like this:
#login_required
def editproject(request, project_id):
project = get_object_or_404(Project, pk=project_id)
if request.method == 'POST':
if request.POST['title'] and request.POST['content']:
project.title = request.POST['title']
project.content = request.POST['content']
project.developer = request.user
project.save()
return redirect('/projects/',project.project_id)
return render(request, 'projects/editproject.html', {'error':'All fields are required.','project':project})
And in the template you can get value like this :
Also in your template change method=put to method=post
and also you need to provide action if you want to update.
<div class="form-group">
<label for="exampleFormControlTextarea1">Title of the project</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="1" name="title">
{{project.title}}
</textarea>
</div>
