got problem in the ajax form submission code - django

<form action="" method="post" class="f-color" id="email-form">
{% csrf_token %}
<label>Name</label>
<input type="text">
<label>From</label>
<input type="email">
<label>Message</label>
<button type="submit">Sent</button>
</form>
<div class="mt-5" id="spin" style="display: none;">
<div class="loader"></div>
</div>
<div id="msg"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(document).on("submit", "#email-form", function(event){
event.preventDefault();
$('#spin').show();
$.ajax({
url: "{% url 'contact' %}",
type: "POST",
data: $("#email-form").serialize(),
success: function(data){
$("#spin").hide();
if(data.status == "success"){
$("#msg").html("<p class='alert alert-success'>we will get back to you as soon as possible</p>" );
$("#email-form").reset();
}
}
})
})
})
</script>
using this code I can submit the form successfully, but after the form submission the message(msg) not showing, the 'if condition statement' is perfectly working (for the testing I gave the alert, the alert was worked)
another problem is form reset, for this I'm using
$("#email-form").reset();
but the form dose't reset
how can I solve these problems

try
$('#email-form')[0].reset();

I got a solution for the resetting form after the ajax form submission
$("#email-form").trigger("reset");

How to get specific id from for loop in django template?

I'm working with django and javascript, I'm trying to follow and unfollow multiple users without refreshing the page. therefore i'm using ajax. The problem which i'm facing right now is that the first follower is getting follow and unfollow no matter if i click on that user or on other user.. its an obvious behavior because i couldn't understand how to get specific id of user from the for loop so that i can use that user in a js function.
{% if follower.user in request.user.userprofile.follower.all %}
<span><a class="btn btn-success" id="follow-button{{follow.id}}" toggle="{{follower}}" type="submit">{% csrf_token %}UnFollow</a></span>
{% else %}
<span><a class="btn btn-warning" id="follow-button{{follow.id}}" toggle="{{follower}}" type="submit">{% csrf_token %}Follow</a></span>
{% endif %}
</div><!--/ followers-body -->
{% endfor %}
<script>
$(document).on('click','a[id^=follow-button]', function (e) {
var user = $('#follow-button').attr('toggle'); //this user is coming the first use of looping object..no matter if i click on the 2nd or 3rd user of the loop.
console.log(user,'im im im tested');
e.preventDefault();
$.ajax({
type: 'POST',
url: '{% url "profiles:toggle" %}',
data: {
user_toggle: user,
csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(),
action: 'POST',
},
success: function (json) {
result = json['result']
console.log(result,"maii mai maima maima a")
if (result) {
document.getElementById("is_following").innerHTML = '<a class="btn btn-success" id="follow-button" toggle="{{user.userprofile}}" type="submit">{% csrf_token %}UnFollow</a>'
}
else
document.getElementById("is_following").innerHTML = '<a class="btn btn-warning" id="follow-button" toggle="{{user.userprofile}}" type="submit">{% csrf_token %}Follow</a>'
},
error: function (xhr, errmsg, err) {
}
});
})
</script>
It is more of JS/JQuery question than a Django one, but here is what I think you are missing.
When you add a listener to an element, you have an option to get the element that was interacted with using the saved word this.
Your problem in the code is that line where you retrieve user. If you replace $('#follow-button') with $(this) then you will get the user that was clicked.
From there you can retrieve the id easily.

Send JSON from Places Autocomplete to Flask

I'm working on my very first web app utilizing the Google Places Autocomplete functionality in the frontend and Flask in the backend.
Current situation:
Whenever an address is selected from the autocomplete suggestions, a variable called 'address' is populated in the background containing the API response as JSON. Using a window alert I can confirm that this part works fine.
To-Do/ issue:
The address variable should be sent over to Flask so that I can do use it going forward.
Using AJAX to post the data however it never seems to reach Flask. The output is always None.
My best guess is that the submit button implemented after the Autocomplete stuff somehow overrides the JSON POST data in order to keep only the actual text which is in the form while submitting*.
Does that make sense? If yes, how can I still send the JSON data successfully? Or is the issue somewhere else?
I would appreciate any help.
Here is my code:
home.html
{% extends "base.html" %}
{% import 'bootstrap/wtf.html' as wtf %}
{% block app_content %}
{% from "_formhelpers.html" import render_field %}
<div class="container">
<form class="form form-horizontal" action="" method="post" role="form" novalidate>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=key&libraries=places&language=en"></script>
<script type="text/javascript">
google.maps.event.addDomListener(window, 'load', function () {
var autocomplete = new google.maps.places.Autocomplete(document.getElementById('autocomplete'),{
types: ['geocode']
});
// autocomplete.setFields('address_components');
google.maps.event.addListener(autocomplete, 'place_changed', function () {
var place = autocomplete.getPlace();
var address = place.address_components;
window.alert(JSON.stringify(address));
}
)})
$.ajax({
type: "POST",
url: "/",
data: address,
success: function(){},
dataType: "json",
contentType : "application/json"
});
</script>
<input type="text" id="autocomplete" size=50 style="width: 250px" placeholder="Enter your location" name=inputkiez>
<a href=# id=autocomplete><button class='btn btn-default'>Submit</button></a>
</form>
<div class="row">
or check out <a href='/result'> the latest reviews from others </a>
<div>
</div>
{% endblock %}
routes.py
#app.route('/', methods=['GET','POST'])
def search():
if request.method == 'POST':
jsdata = request.get_json()
flash('Data is: {}'.format(jsdata))
return redirect('/review')
return render_template('home.html')
#app.route('/review', methods=['GET', 'POST'])
def review():
reviewform = ReviewForm()
if reviewform.validate_on_submit():
userreview = Reviews(
reviewcriteria1= reviewform.reviewcriteria1.data,
reviewcriteria2= reviewform.reviewcriteria2.data,
reviewcriteria3= reviewform.reviewcriteria3.data,
)
db.session.add(userreview)
db.session.commit()
return redirect('/result')
return render_template('review.html', form=reviewform)
*The text in the form would include the address selected from Autocomplete but without any additional data obviously. I even managed to pass this text to the next page with request.form.to_dict() but this is not good enough for my use case since I also want at least the postal code to be sent over.
This is not the exact answer to my question but I found a way to send over the data to flask without having to bring in JSON/AJAX at all.
The trick is to send the data from the Autoplaces response as a hidden input of the form:
<form method="post" action="">
<input id="userinput" placeholder="Enter a location" type="text" name="name" class="form-control"><br>
<div id="map" style="height: 300px;width: 300px; float: none; margin: 0 auto;"></div><br>
<input type="hidden" name="address" id="address">
<input type="submit" name="submit" value="Submit" class="form-control btn btn-primary">
<div>or check out <a href='/result'> the latest reviews from others </a></div>
</form>
Then in routes.py you can easily get the data like this:
#app.route('/', methods=['GET','POST'])
def search():
if request.method == 'POST':
address = request.form['address']
# do something
This is basically a slightly modified version of the solution posted here (YT video).

Django - POST method not working for those forms created within a FOR loop in template

I'm using a for loop in a template to create multiple forms with method="post" that work with Ajax. But only the form for the first element of items_list works fine, the rest do not work at all showing error 405 0 Method Not Allowed. I think they all should work the same way. And just wondering if this issue was caused by a for loop or something else.
cart_items.html:
<script>
$(document).ready(function () {
$("#remove").click(function (event) {
event.preventDefault();
$.ajax({
url: '{% url "cart:remove_from_cart" %}',
type: "POST",
dataType: 'json',
data: {bookID: $('#idInput').val()},
success: function (response_data) {
alert('works fine')
},
error: function (response_data) {
console.log('error occurred');
}
});
});
});
</script>
{% for book in items_list %}
<div class="items">
<p id="title"> {{ book.book.title }}, quantity: {{ book.quantity }} </p>
<form method="post">
{% csrf_token %}
<input id="idInput" value="{{ book.book.id }}" >
<button id="remove" type="submit"> Remove</button>
</form>
</div>
{% endfor %}
The code in the function body below is just for testing. Once the first form works, I guess the problem was not caused by the function view.
cart/views.py:
#csrf_exempt
def remove_books(request):
cart = Cart.objects.get(user=request.user)
if request.method == 'POST':
passed_id = request.POST['bookID']
secured_id = int(passed_id)
response_data = {
'quantity': secured_id
}
return JsonResponse(response_data)
<script>
$(document).ready(function () {
$(".remove").click(function (event) {
// event.preventDefault(); // don't think it should be required with button type=button
var book_id = $(this).parent().find('.idInput').val(); // find correct input box.
var csrf = $('input[name="csrfmiddlewaretoken"]').val(); // get csrf token in variable.
// there are multiple ways to get csrf token, I personally like this ^^, see https://docs.djangoproject.com/en/2.1/ref/csrf/#ajax for more
$.ajax({
url: '{% url "cart:remove_from_cart" %}',
type: "POST",
dataType: 'json',
data: {
bookID: book_id,
csrfmiddlewaretoken: csrf // add csrf token to post data
},
success: function (response_data) {
alert('works fine')
},
error: function (response_data) {
console.log('error occurred');
}
});
});
});
</script>
{% csrf_token %} <!-- It will render a hidden input field with csrf token in it. Keep it outside for loop but in html. No need to render exactly same element multiple times. -->
{% for book in items_list %}
<div class="items">
<p class="title"> {{ book.book.title }}, quantity: {{ book.quantity }} </p>
<form method="post">
<input class="idInput" value="{{ book.book.id }}" > <!-- use class not id -->
<button class="remove" type="button"> Remove</button> <!-- you can use button type=button to avoid form submit and hence avoid event.preventDefault(); in js -->
</form>
</div>
{% endfor %}

Having trouble submitting my form using Dojo

I am using Django 1.5 and Dojo 1.8. I am trying to get Dojo to submit a form back to a Django view when I click a button.
Here is my Django view:
def report(request, report_id, report_url=None, template='report_parameters.html'):
if request.method == 'POST':
form = ReportParametersForm(request.POST)
if form.is_valid():
report_params = form.save()
html = "Success!"
return HttpResponse(html)
else:
form = ReportParametersForm()
return render(request,template, {
'form': form,
'report_url': report_url,
'report_id': report_id,
})
Here is the html page:
<div id="report_body">
<form data-dojo-type="dijit/form/Form" id="parameters_form" data-dojo-id="parameters_form">
{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<p><button id="submit_parameters" dojoType="dijit.form.Button" type="submit">Submit</button></p>
</form>
</div>
<script type="dojo/on" data-dojo-event="submit" data-dojo-args="e">
e.preventDefault();
require(["dojo/dom", "dojo/request", "dojo/dom-form"], function(dom, request, domForm){
on(dom.byId("submit_parameters"), "click", function() {
console.log("Dojo Post");
request.xhr("/report_parameters/report_id/report_url/", {
method: "post",
handleAs: "json",
data: domForm.toJson("parameters_form"),
}).then(
function(response){
alert(response);
dom.byId("report_body").innerHTML = "Report!";
},
function(error){
dom.byId("report_body").innerHTML = "<div class=\"error\">"+error+"<div>";
}
);
});
});
</script>
When I click the Submit button, I want to send a POST request to the url passing the data I have in my form. However, right now when I click Submit, the page reloads with a url looking something like this: /?csrfmiddlewaretoken=Y9gaNMFRWZNXMbJ2L3Ev7A5iKPGTuWeF&param_1=0&param2=0/report_parameters/report_id/report_url/.
I don't see the Dojo Post that should be appearing in my console.
How do I get my form to submit?
This fiddle seems to do what you want.
The major differences seem to be:
The <form> is actually a <div>. The Dojo documentation for Form links to reasons why this is done for IE.
All the related event script is inside the form <div>.
Remove the on(dom.byId("submit_parameters")... code, as there's already a declarative submit event handler.
HTML code:
<div id="report_body"></div>
<div data-dojo-type="dijit/form/Form" id="parameters_form" data-dojo-id="parameters_form" encType="multipart/form-data" action="" method="">
<input name="dummy" value="dummy">
<script type="dojo/on" data-dojo-event="submit" data-dojo-args="e">
console.log("submit");
e.preventDefault();
require(["dojo/dom", "dojo/request/xhr", "dojo/dom-form"], function(dom, xhr, domForm) {
console.log("Dojo Post");
var url = "/report_parameters/report_id/report_url/";
var data = domForm.toJson("parameters_form");
// overwrite url and data for jsfiddle
url = "/echo/json/";
data = {
json: data
};
xhr(url, {
method: "post",
handleAs: "json",
data: data,
}).then(function(response) {
alert(JSON.stringify(response, null, 2));
dom.byId("report_body").innerHTML = "Report!";
}, function(error) {
dom.byId("report_body").innerHTML = "<div class=\"error\">" + error + "<div>";
});
});
</script>
<button data-dojo-type="dijit/form/Button" id="submit_button" type="submit" name="submitButton" value="Submit">Submit</button>
</div>
JS code:
require(["dojo/parser", "dijit/registry", "dijit/form/Form", "dijit/form/Button", "dijit/form/ValidationTextBox", "dijit/form/DateTextBox", "dojo/domReady!"], function (parser, registry) {
parser.parse().then(function () {
console.log("parsed");
console.log(registry.byId("parameters_form"));
console.log(registry.byId("submit_button"));
});
});
I had to modify the above slightly. This is what eventually worked for me:
<div id="report_body"></div>
<form data-dojo-type="dijit/form/Form" id="parameters_form" data-dojo-id="parameters_form" encType="multipart/form-data" action="" method="POST">
{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<script type="dojo/on" data-dojo-event="submit" data-dojo-args="e">
e.preventDefault();
require(["dojo/dom", "dojo/request/xhr", "dojo/dom-form"], function(dom, xhr, domForm){
var url = "/report_parameters/report_id/report_url/"
var data = domForm.toObject("parameters_form")
xhr(url, {
method: "post",
data: data,
}).then(
function(response){
alert(response);
dom.byId("report_body").innerHTML = "Report!";
},
function(error){
dom.byId("report_body").innerHTML = error;
}
);
});
</script>
<p><button id="submit_parameters" dojoType="dijit/form/Button" type="submit" name="submitButton" value="Submit">Submit</button></p>
</form>
Using either the <div> or <form> tags to wrap the whole thing worked for me.

sent image data using jquery ajax won't be saved using ModelForm

I'm going to edit an ImageField using jquery ajax,so I've used jquery form plugin,this is the code:
<form id='form_upload' action="." method="POST" enctype="multipart/form-data">
<input type='file' id='id_HeadImage' name='id_HeadImage' />
</form>
<script typr="text/javascript">
var options = {
dataType: 'xml',
url: '{% url DrHub.views.editNews param1,param2 %}',
}
$('#form_upload').ajaxSubmit(options);
</script>
in <head>:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script>
<script src="http://malsup.github.com/jquery.form.js"></script>
and in server side :
if ('id_HeadImage' in request.FILES) and (request.FILES['id_HeadImage']):
gForm=GalleryForm(request.POST,request.FILES,instance=newsInstance.gallery_ptr)
if gForm.is_valid():
gForm.save()
as U can see I'm going to edit ImageField of a model named Gallery.
How can I do this?
this is Gallery Model:
class Gallery(models.Model):
HeadImage = models.ImageField(upload_to="gallery",blank=True,null=True)
While gForm.is_valid() returns True,but It won't be saved and Image of HeadImage Field won't be changed.
Note : I've checked this in firebug and I'm sure that data is sent and request.FILES has value.
what's wrong here?
EDIT : I've worked based on this article: http://www.laurentluce.com/posts/upload-to-django-with-progress-bar-using-ajax-and-jquery/
Try ajaxForm in place of ajaxSubmit:
`
<form id='form_upload' action="." method="POST" enctype="multipart/form-data">
<input type='file' id='id_HeadImage' name='id_HeadImage' />
</form>
<div id="empty">
</div>
<script type="text/javascript">
function handleResult(responseText, statusText, xhr, $form) {
//do stuff here
};
jQuery(document).ready(function() {
var options = {
target: '#empty',
// Not sure if you should use xml here, I would suggest json . ,
dataType: 'xml',
url: '{% url DrHub.views.editNews param1,param2 %}',
success: handleResult,
}
$('#form_upload').ajaxForm(options);
});
</script>`
