allow both edits and additions in form

[Becka R.]

Hi,

I've been tryign to understand this for a while, and am pretty stuck.  I've googled extensively.

My form currently allows me to add items to teh datatable.

I want to be able to, in the same template, edit each row.  I put a button in each table row, and I want to get the pk for the item in that row, and then edit that item.  I don't understand how this is done. I've tried declaring an instance, but I got lost in the fog after that.  Thanks so much.  Code is below. 

I have a basic modelform:

models:

class Inventory(models.Model):

item = models.CharField(max_length=20, blank=True)

needs_repairs = models.BooleanField(default=True)

date = models.DateTimeField(auto_now_add=True, blank=True)

def __str__(self):

return '%s %s'%(self.item, self.needs_repairs)

views

def inventory(request):

    model = Inventory

    stuff = Inventory.objects.all()

   form = InventoryForm(data = request.POST)

    if request.method == "POST":

        if form.is_valid(): 

            obj = form.save(commit=False)

            obj.save() 

    else:

        form = InventoryForm()

    context = RequestContext(request)

    return render_to_response('inventory.html', {

            'form':form, 'stuff':stuff

            }, RequestContext(request))

forms

class InventoryForm(ModelForm):

    class Meta:

        model = Inventory

        fields = '__all__'

template

<div>

<div class="formfloatleft">

<h2>Truck Inventory </h2>

<div class="tablewrap">

<table class="gradienttable">

<thead>

<tr>

<th><p>Whatcha got?</p></th>

<th><p>Needs Repairs</p></th>

<th><p>Change</p></th>

</tr>

</thead>

<div class="datatables">

{% for things in stuff %}

<tr class="datarow">

<td>{{things.item}}</td>

<td>{{things.needs_repairs}}</td>

<td>

<form method="post">

           {% csrf_token %}

           <input type="submit" value="edit or remove me">

       </form>

   </td>

</tr>

{% endfor %}

</div>

</table>

</div>

</div>

<div class='formfloatright' >

<h2>Add stuff</h2>

<form action="" method="post">

 {% csrf_token %}

  <ul>

   {{ form.as_ul}}

</ul>

 </ul>

 <input type="submit" value="Save" />

</form>

</div>

</div>

You code is not very clear,

you could make your changes to your view as below:

views

def inventory(request,id):
    if request.method =='POST':
        staff=Inventory.objects.get(id=id)
        form=InventoryForm(request.POST,instance=staff)
        if form.is_valid():
            form.save()
            return render_to_response('display_successful_message.html')
   else:
        staff=Inventory.objects.get(id=id)
        form=InventoryForm(instance=staff)
        return render_to_response('inventory.html')

Hope this helps.

Cheers,

Sum
