Confused by sizes

[John Whitmore]

I've added photologue to my zinnai based blogging site so that I can upload photos to my media directory and then refer to them in blog posts.

I'm confused by how sizes are implemented. I have an original photo of size 1600x1200 but if I only want to display it in a blog post at a size of 400x300 I define a new size in photologue of 400x300. I don't want the image cropped, just resized. So now I have an image and a size in photologue but I can't find how I refer to that image at a requested size in an html "img" tag.

Been looking through documentation and can't find any mention of that aspect of operation. Any advice would be great.

Hi John,

I think that this crucial information is missing from the documentation and will need adding :-)

Each Photo instance has a method get_<size>_url() where <size> is the name of the PhotoSize that you have defined in Photologue.

Hope to help,

Richard

Hi Richard,

Thanks a million for getting back to me. I've got that from Internet searches but struggling to "wire" that up. In my blog post I was trying something like:

<img src="{% get_blog_post_url() %}/photo.png"/>

But I'm doing that in a zinnai blog post so might have to add another line to the top of the template.

Looking into this a bit more I need to add a new URL to photologue's urls.py and a view which is in the form:

photologue/size/photo

that would simply return the image file in /media/photologue

[John Whitmore]

Got it. Added my own line to my own urls.py

    url(r'^blog_photo/(\w+)/', blog_photo),

And then in my views

def blog_photo(request, requested_slug):
    logger.debug("photo_blog_post request for %s" % (requested_slug))

    photo = Photo.objects.get(slug=requested_slug)
    url = photo.get_blog_post_url()

    logger.debug("URL %s" % (url,))

    return redirect(url)
