Question

Transmit the "form data" over to the AJAX request

Snippet of HTML code:

<form id="custom_form" name="custom_upload" method="POST" enctype="multipart/form-data">
<label>Choose File:</label>
 <input id="in" name="csv_file" value="Add CSV" type="file" required />
<table class="opttable">
  <tr>
     <td>
         Title<span style="color: red;">*</span>
     </td>
     <td>
     <select id="select1" class="optselect form-control">
          <option>abc</option>
          <option>cde</option>                                                      
      </select>
      </td>
   </tr>
</table>
<input type="submit" value="Submit" class="onsubmit">
</form>

JavaScript section:

$('.onsubmit').on('click', function (e) {
      var id = {{id}}
      var fd= $('form').serialize()
      console.log(fd)
      $.ajax({
       url: '/someview/'+id,
       type: 'POST',
       data: fd,
       sucess: function(data) {
       console.log(data);
       },
       error: function(err) {
         console.log('err: '+err);
       }
    });
});

This is a code implementation where I am trying to include both file and regular data in an AJAX call. Utilizing the serialize method for converting form data into strings, but wondering how to handle file inclusion along with it.

Answer 1

Answer №1

Using the method $('form').serialize() will generate an array of objects structured as shown below: </p>

<pre><code>[
{"Name":"elementname","Value":"12"},
{"Name":"elementname2","Value":"hello"}
]

You have two options for sending this data. You can either stringify the entire array and send it like this:

data: { "formData" :JSON.stringiy(fd)}

or

You can convert the array into simple key-value pairs and send them to the server as a JSON string:

dataToSend={}

for(var v=0; v<fd.length;v++){
dataToSend[fd["Name"]] = fd["Value"]; 
}

and then include it in the data like this:

data: { "formData":JSON.stringify(dataToSend)}

To handle this data on the server side, you can use the following Python code:

import json
json.loads(request.POST.get('formData'))

Answer №2

To send data to the server, you can utilize the FormData object and append the desired values.

If you are sending a post request, ensure you have a csrf_token. It should be stored within your HTML page. Here's an example:

<script>
    var CSRF_TOKEN = '{{ csrf_token }}';
</script>

$('.onsubmit').on('click', function (e) {
      e.preventDefault();
      var id = {{id}};
      var formData = new FormData();
      formData.append('csvFile', $('#in')[0].files[0]);
      formData.append('csrfmiddlewaretoken', CSRF_TOKEN);

    $.ajax({
       url : '/someview/'+id,
       type : 'POST',
       data : formData,
       processData: false,
       contentType: false,
       success : function(data) {
       },
       error: function(data){
       }
    });
});

To access the file in your views, you can retrieve it using the following code:

csv_file = request.FILES.get('csvFile')
