Im trying to submit two POST forms with Django using ajax, but just one of the forms has the method POST in it. I dont really know what to do here, the error is probably in the Javascript, but i dont see why the first form submit with POST method and the second doesn't, i tried to search in the internet but i think i didnt search the right question.
(sorry for my bad english)

I added {% csrf_token %} in my html file trying fix this - didn't work. I've found online this tag example:
<input type="hidden" id="csrf_token" value='{"csrfmiddlewaretoken": "{{ csrf_token }}"}'>.
Unfortunately I don't know how to use it in order to fix my error.
Thanks for help
I guess, instead of post a form you are posting values.
You need to add csrfmiddlewaretoken key while execute $.post() statement.
This is not Tested but it may be fix your problem
csrfmiddlewaretoken: document.getElementsByName('csrfmiddlewaretoken')[0].value
or
csrfmiddlewaretoken: $('[name=csrfmiddlewaretoken]').val()
add this line in HTML file by updating
$.post("ajax-sign-up",
{
username: $("#username").val(),
email: $("#email").val(),
password: $("#password"),
csrfmiddlewaretoken: $('[name=csrfmiddlewaretoken]').val()
},
updated code is :

If you're just posting the contents of a HTML form with id signup-form (add that to the <form>), and your form has the {% csrf_token %}, then you can do that in ajax using:
$.post("ajax-sign-up", $("#signup-form").serialize(), function(data, status){...})
When running the webapp a 404 error appears, the error doesnt even allow my error html to run even when changing it to the most basic of templates. I dont know where my request is being not found.
Ive tried removing all of the style sheets from base.html to see if its those, I tried changing the error.html to see if it will actually run I've attempted to comment out all url_for's in the html files.
I commented out the results bit so i dont think its that.

So what happens is that the form doesnt appear and it seems only base.html appears with nothing else, the icon doesnt appear either but I tried commenting that out and that doesnt work.
The error printed is "404 Not Found: The requested URL was not found on the server. IF you entered the URL manually please check your spelling and try again"
To future people: I solved because the base.html did not specify where it had to be extended. The correct base.html code would be:

You need to render your forms within form tags. See the docs: https://docs.djangoproject.com/en/1.10/topics/forms/#the-template
<form>
{% csrf_token %}
{{ rform }}
</form>
<form>
{% csrf_token %}
{{ lform.as_p }}

I am trying to build a blog using flask. SimpleMDE is used as post editor(html code below). I want to save the markdown content to local file and render by flask-misaka in jinja2.
In SimpleMDE, I can get raw markdown content by simplemde.value(). But when I pass simplemde.value() to var in javascript. "\n" is missing aftering passing. I think it may have some "magic" tools in javascript. The html code return 2 alert message, first message contains line feed, the second doesn't.
Could somebody give me some hits about this problems?

If you want to get raw markdown, just use simplemde.value().
When you put raw markdown into normal textarea, it turns into pure text.

This is my views.py
def homepage(request):
hotel_list=Hotels.objects.all()
context={'hotel_list':hotel_list}
return render(request, 'polls/homepage.html',context)
def wholelist(request):
hotelvar=request.POST.get('service_type')
if hotelvar=='Hotels':
city_list=Hotels.objects.filter(city_name__iexact=request.POST.get('searchabc'))
if not city_list:
hotel_list=Hotels.objects.all()
context={'hotel_list':hotel_list}
return render(request, 'polls/homepage.html',context)
pricemin=200
pricemax=800
context={'pmin':pricemin,'pmax':pricemax,'city_list':city_list}
return render(request, 'polls/list.html',context)
i get the following error when refreshed
UnboundLocalError at /polls/wholelist/
local variable city_list referenced before assignment
city_list is being passed from the homepage, but when page is reloaded it not being passed. Is there a way to pass it when page is refreshed?
when hotelvar not equal to 'Hotels', variable city_list is not set
def wholelist(request):
hotelvar=request.POST.get('service_type')
city_list = None
if hotelvar=='Hotels':
city_list=Hotels.objects.filter(city_name__iexact=request.POST.get('searchabc'))
if not city_list:
hotel_list=Hotels.objects.all()
context={'hotel_list':hotel_list}
return render(request, 'polls/homepage.html',context)
pricemin=200
pricemax=800
context={'pmin':pricemin,'pmax':pricemax,'city_list':city_list}
return render(request, 'polls/list.html',context)
