In my project, there is a form and a table with checkboxes, based on the data entered in the form and the checkboxes, I fill 2 databases and redirect the user to a page where information from one table is displayed, it all worked very well until I got to editing the records, I decided I do it with UpdateView, passing in template_name the same template as before adding records:

here is the add function and the edit class:

class CampaignEditor(UpdateView):
    model = Campaigns
    template_name = 'mailsinfo/add_campaign.html'
    form_class = CampaignsForm
def add_campaign(request):
    if request.method == 'POST':
        addCampaignDataToDB(request.POST)
    data = list(Emails.objects.values())
    data = MailsTableWithoutPass(data)
    form = CampaignsForm()
    data_ = {
        'form': form,
        'data': data
    }
    return render(request, 'mailsinfo/add_campaign.html', data_)

But when calling the url to change my data table is empty and there are no selected checkboxes there, all processing of the form works fine

Here is the template I use, and the function that writes the data into the tables:

<div>
    <div >
        <div >
            <form method="post" id="newCampaign">

                    {% csrf_token %}
                    {{ form.name }}<br>
                    {{ form.subject }}<br>
                    {{ form.body }}<br>
                    {{ form.user_guid }}<br>

            </form>
        </div>
        <div >
            <table
            id="table"
            data-height="480"

            >
                <thead>
                    <tr name="mails-info">

                        <th data-field="state" data-checkbox="true"></th>
                        <th data-field="id">ID</th>
                        <th data-field="email">Email</th>
                        <th data-field="source">Source</th>
                        <th data-field="created_at">Created at</th>
                        <th data-field="modified_at">Modified at</th>
                    </tr>
                </thead>
            </table>
        </div>
    </div>

        <script>
            var $table = $('#table')

            $(function() {
                var data =   {{data|safe}}
                $table.bootstrapTable({data: data})
            })
        </script>


<button id="button2"  type="submit" style="margin-left: 2%">Save campaign</button>

</div>
<script>
             var table = $('#table')
             var button = $('#button2')

             $(function() {
                button.click(function () {
                    ids = []
                    for( i in table.bootstrapTable('getSelections')){
                        ids.push(table.bootstrapTable('getSelections')[i].id)
                    }
                    console.log(ids)
                    var form = $('#newCampaign')[0];
                    var formData = new FormData(form);
                    formData.append("IDs", ids);
                    $.ajax({
                          type: "POST",
                          enctype: 'multipart/form-data',
                          url: '',
                          data: formData,
                          processData: false,
                          contentType: false,
                          dataType: 'text/json',
                          success: function(){ alert("All ok") },
                          error: function() {
                                window.location.replace('..');
                           }

                    });
                })
             })
        </script>

def addCampaignDataToDB(req):
    mails_id = req
    print(mails_id)
    formCampaigns = CampaignsForm(req)
    IDs = req['IDs']
    if IDs != '':
        IDs_list = IDs.split(',')
        user_guid = req['user_guid'][0]
        for i in IDs_list:
            CampaignEmail.objects.create(email_guid=int(i), campaigne_guid=int(user_guid))

    if formCampaigns.is_valid():
        formCampaigns.save()

Is there any method when calling this url:

path('editCampaign/<int:pk>', views.CampaignEditor.as_view(), name='editCampaign')

, in addition to the recorded form, to receive a table of data with checkboxes available for editing?

I apologize in advance if I did not provide any information or explained something unclearly

CodePudding user response：

You aren't passing any additonal data to the update form. The update view is separate and doesn't inherit data from the add-campaign view, so if you need additional context, you can:

class CampaignEditor(UpdateView):
    model = Campaigns
    template_name = 'mailsinfo/add_campaign.html'
    form_class = CampaignsForm
    def get_extra_context(self):
        //call the super context from the parent class
        context = super().get_context_data(*args, **kwargs)
        data = list(Emails.objects.values()) #you may want to further filter for update purposes
        data = MailsTableWithoutPass(data)
        context['data'] = data
        return context

I'm not sure how much of the form is being created by javascript - it may be worth remembering that django templates are done serverside, so if you need to populate fields that are created client-side by JS, you'll need to put their values somewhere as JS variables that you can refer to later,eg,

<script>
    {% for field in form %}
       {{field.name}} = "{{field.value}}"
    {% endfor %}
<script>
