I have a very basic Django view:
def myview(request):
if request.method == 'POST':
if 'button1' in request.POST:
form1 = form = myForm(request.POST)
# check whether it's valid:
if form.is_valid():
profile = form.save()
profile.user = request.user
profile.save()
messages.success(request, f"Success")
return HttpResponseRedirect(request.path_info)
else:
form = myForm()
return render(request,
"main/mytemplate.html",
context={"form":form})
And its template:
<form method="post" novalidate>
{% csrf_token %}
{% include 'main/includes/bs4_form.html' with form=form %}
<button name="button1" type="submit" class="btn btn-primary">SUBMIT</button>
</form>
Everything works here, when this form is used, some data is saved on my DB. What i would like to change, though, is the page reload after the form is used.
When the Submit button is hit, the page will be refreshed. Since it makes the navigation way slower, i would like to have the view not refreshing the page each time the form is used.
Is it possible to accomplish this in Django? For example, instead of refreshing the page, i would like to only load part of it, or to have a 'Reload' icon while the view is doing its work.
I'm pretty new to Ajax, so i don't know how to get started on this.

I am trying to restrict user who is logged in - from updating , deleting other users posts.
However when I Try to use {% if user.id == post.user.id%} , the page becomes blank even for the user who is editing his own post. The same goes for deleting.
It works on mainpages - where posts are displayed (it hides edit and delete buttons).
What is the reason that the post is not showing inside the template ?
I don't understand that even {{post.user}} in postform.html does not appear , neither on deleteform etc. - why this data of objects of a post is not being sent to postform.html ?
You should change the context to access the post instance from your template.
context = {'form': form, 'post': post}
You can only access the context values from the templates. So pass the ones you want to use while you are returning a response.
I have a scheduling app with Event objects and I'm trying to create a form that will allow the user to update an Event that already exists by the press of the button. However, when the user presses the button it doesn't seem to do anything. It just refreshes the page.
{% for a in availability %}
<form method='POST'>
<li><a class="btn btn-primary" href="{% url 'updateevent' a.id %}" type="submit" role="button">{{a.day}}: {{a.start_time}} - {{a.end_time}}</a></li>
</form>
{% endfor %}
view.py:
def updateevent(request, pk):
if request.method == 'POST':
try:
form = EventForm(data=request.POST, instance=post)
updatedEvent = form.save(commit=False)
updatedEvent.requester_user = request.user
updatedEvent.notes = None
updatedEvent.save()
return redirect('/')
except ValueError:
print(form.errors)
return render(request, 'events/createevent.html', {'form':EventForm(), 'error':'There was an error. Please make sure you entered everything correctly!'})
else:
return redirect('/')
I want the user that presses the button to become the "requester_user", a blank field in my Event object. How can I make this happen?
Anchor tag triggers GET request. You should use <button type="submit"></button> or <input type="submit"> for POST request.
I have a simple form in Django, and in my template I want to display each individual object for the whole queryset which I am saving the form to. The error I am getting is that my form does not seem to submit on the first attempt. Only when I click the submit button, manually refresh the page and then 'confirm form resubmission' do I see my updated queryset objects displayed in the template.
I am saving my form like this in my views:
exercise_name = ExerciseName.objects.all()
if request.method == 'POST':
form = ExerciseNameForm(request.POST)
if form.is_valid():
form.save(commit=True)
else:
form = ExerciseNameForm()
and passing the queryset to the template through the following context:
{ 'exercise_name': exercise_name }
and iterating through it like
{% for exercise_title in exercise_name %}
#content displaying each iteration
{% endfor %}
with my form to update it like:
<div>
<form method = "POST">{% csrf_token %}
{{form.as_p}}
<button type="submit" class="save btn btn-default">Save</button>
</form>
</div>
I am not sure why it is making me refresh the page and resubmit the form again in order to see the updated queryset after submitting the form?
You should be doing something like this:
if request.method == 'POST':
form = ExerciseNameForm(request.POST)
if form.is_valid():
form.save(commit=True)
return HttpResponse("data submitted successfully")
else:
return render(request, "your_template.html", {'form':form})
else:
form = ExerciseNameForm()
return render(request, "your_template.html", {'form':form})
I want to build a very simple webapp that takes a user's text, runs a function on it that alters it and then displays the altered text. I have the code for the function but everything else is unclear.
I am very new to django and just need a push in the right direction with this problem. At the very least, tell me what to google, I've went through several tutorials but neither of them dealt with this kind of task.
Thanks in advance!
Define a form; in forms.py under your app's folder
class MyForm(forms.Form):
myinput = forms.forms.CharField(max_length=100)
Define a function in your views.py
import .forms
def handle_form(request):
if request.method == 'POST': # If the form has been submitted...
form = MyForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
# Process the data in form.cleaned_data
# ...
return HttpResponseRedirect('/thanks/') # Redirect after POST
else:
form = MyForm() # An unbound form
return render(request, 'handle_form.html', {
'form': form,
})
Add a template
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Submit" />
</form>
Of course you need to add it to your urls.py
Most info was copy pasted from: https://docs.djangoproject.com/en/1.8/topics/forms/
I'm during the form tutorial on https://docs.djangoproject.com/en/1.8/topics/forms/. I'm trying to make a simple form element, which will be POSTing some data. This is function launched in urls.py:
def get_name(request):
# if this is a POST request we need to process the form data
if request.method == 'POST':
# create a form instance and populate it with data from the request:
form = NameForm(request.POST)
# check whether it's valid:
if form.is_valid():
# process the data in form.cleaned_data as required
# ...
# redirect to a new URL:
return HttpResponseRedirect('/thanks/')
# if a GET (or any other method) we'll create a blank form
else:
form = NameForm()
return render(request, 'name.html', {'form': form})
HTML code looks as follows:
<form action="/your-name/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit" />
</form>
When I input some data to form and click 'Submit' button, function connected to /your-name/ URL is launched and I'm redirected to /your-name/. I'm wondering why function connected to /thanks/ URL is not launching. How can it be reached?
For the view to work, the form's action /your-name/ must be served by your view get_name.
You haven't shown your url patterns, so it's impossible to tell whether the mistake is there or not.
