        return render(request,'edit/home.html',{'name':request.session['account'],'con':sql})

The home.html

the page code:


from django.core.paginator import Paginator,EmptyPage,InvildPage

    q=Edit.objects.all().order_by('id')
    paginator=Paginator(q,1)    #set how many rows in one page, this is set one rows in one page
    try:
        page=int(request.GET.get('page',1))
    except ValueError:
        page=1
    try:
        content=paginator.page(page)
    except (EmptyPage,InvalidPage):
        content=paginator.page(paginator.num_pages)

About Paginator information:


>>>from django.core.paginator import Paginator
>>>objects=['12','dfs','tony','jhon','jery','max','heeny']
>>>p=Paginator(object,2)    #set veery page have 2 rows
>>>p.count    #how many content

>>>p.num_pages    #how many pages

>>>p.page_range #the page list

>>>page1=p.page(1)    #first page
>>>page1        #show the 1st page content index list

{% if content.has_previous %}
    <a href="?page={{content.previous_page_number}}">NEXT</p>
{% end if%}
<span class="current">
    current page: {{content.number}} / total pages: {{content.paginator.num_pages}}


{% if content.has_next %}
    <a href="?page={{content.next_page_number}}">PREVIOUS</a>
{% endif %}

Django Photo Upload

In index.html add upload part:

<input type="file" name="files" />

Create forms.py in edit part.


from django import forms

class NewTopicForm(forms.Form):
    title=forms.CharField(max_length=50,error_message={'required':'Don\'t empty'})
    image=forms.ImageField(required=False)

Update “model.py”, add “img” item.


img=models.ImageField(upload_to="templates/pic/",blank=True,null=True)

Update “views.py”


if 'files' in request.FILES:
    image=request.FILES['files']
else:
    image=None

Then we upload the photo, update “views.py” to save the img path.
