Re: How to get a variable from an ajax request and use it in another application in Django?

[David Nugent]

There's a little more to handling session data than what you have there
(unless code is missing?).

IIRC you need to set `session.modified = True` in order to persist the data.

Where are you serialising the session data? db, redis .. ?

 Sorry I did not ask the question well.
 Question:
 How to first send some data with an Ajax request to Django view and
 then with a post request, send the form information to the same view and
 use the data sent in the previous request (Ajax request) in the second
 request ?

 def planing(request):

 if request.is_ajax():
 # Get user location from user location.js file:
 latitude = request.POST.get('latitude', None)
 longitude = request.POST.get('longitude', None)


 elif request.method == "GET":
 return render(request, "tourist/planing.html")


 elif request.method == "POST":
 # Here I want to take the form data and have
 #the previous request data (latitude, longitude) here and do a series
 of processing.

DateField and TimeField rendered as textfield in Django

[Vishal Pandey]

Hi everyone,
Whenever we use DateField and TimeField, django renders its html input 
field type as text.
I know it could be changed by customising the attributes in form class, but 
why is not by default.
I am also aware of the fact that date and time are supported by almost all 
browsers but not datetime-local.
Is it designed so?
If not, can I work upon this and make a PR in django's repository. ?

Thanks and Regards,
Vishal Pandey

You should tell us some relevant details, e.g. how you are deploying 
your project, any error messages, which instructions you have followed 
for deploying etc. so someone actually has a chance of helping you.




should i use postgres ???



Static files and the choice of database are not related so that won't 
make a difference.



Please HELP



Please don't SHOUT.

Kind regards,

Re: Get data from table rows and save in database

[Jet Ezra]

STEPS
1. You will add a name attribute to all your input fields.
2. Add the crsf_token django template in-built filter to support 'POST'
3. Change your form's method to 'POST'
4. Add an action attribute and set it to your view
5. Then the JQUERY part will be as follows
6. Don't forget to give your form ad ID
Then
 $("#form_id").submit(function(e){
e.preventDefault()  //prevent the  default submit behaviour of a form
let data = $(this).serialize() // this picks all data basing on the name
attribute including the csrf_token
let URL = $(this).attr('action') //this pick the right URL like
http://localhostL:8000/add

//now perform the request
$.ajax({
url:url,
data:data,
type: "POST",
dataType: "json", // or the data type you expect from your response
beforeSend: function(){
// optional-> whatever you want to access before executing the request
// eg showing some loader
},
success: function(response){
// whatever you want to do on successful request
},
complete: () =>{
//whatever you want to do when  the request is complete
// stopping some loader
}

})
})
