[mezzanine-users] Re: Thumbnail Tag with Prefetch Related Set Only Works on Last Image

[Matt Mansour]

Nevermind. I think all is working as expected. 

I just needed to clean up s3 after all the uploads during development.

Re: [mezzanine-users] Thumbnail Tag with Prefetch Related Set Only Works on Last Image

[Matt Mansour]

Upon further digging it has nothing to do with pre-fetch related.  It has
to do with where I get my media from.

All images in my object list are thumbnailed when I run media from my local
server.

However, if I run media from s3 only some images are thumbnailed.

Has anyone run into this issue?

[mezzanine-users] Thumbnail Tag with Prefetch Related Set Only Works on Last Image

[Matt Mansour]

Hi All -

I'm probably overlooking something. Using the mezzanine thumbnail tag I am 
trying to thumbnail all related images in my object list. However, only the 
last image in the set gets thumbnailed. 

I've never seen this before. I am wondering if it's because I am using 
prefetch_related. 

Below is my code. Please let me know if anything wrong stands out. 

Thanks

{% for listing in listings %}
{{ listing.title }}

{% with image=listing.images.all|first %}

{% endwith %}

{% endfor %}

[mezzanine-users] How include a form in index.html?

[sg . oleksandr . p]

Hello,
sorry, i'm new in Mezzanine. I've made a form with dedicated route. But I 
wish to have the form also on the main page (index.html).

RE: [mezzanine-users] default settings for users / blog posts

[Eduardo Rivas]

The “is_staff” flag only allows users to log into the admin. Groups and 
permissions determine which models they can add/edit/delete.

For future reference I have this in my models.py file : 

+++
from django.db.models.signals import post_save
from django.contrib.auth.models import User, Group
from mezzanine.core.models import SitePermission

def add_user_to_public_group(sender, instance, created, **kwargs):
"""Post-create user signal that adds the user to member group."""

try:
if created:
instance.groups.add(Group.objects.get(name='member'))
sender.objects.filter(id=instance.id).update(is_staff='1')
siteperms = 
SitePermission.objects.create(user=sender.objects.get(id=instance.id))
siteperms.sites.add(2)
except Group.DoesNotExist:
pass

post_save.connect(add_user_to_public_group, sender=User)
+++


I have created a group "member" with permissions to create/edit/delete blog 
posts.  Is that necessary or does the "staff" value override those 
permissions?
