I am (still) migrating a 'super old' html site to Plone.
I have about 18.000 'pages' containing one or more images. Usually, the images also have a Caption.
I want to have first image as lead-image (example skipshistorie )
What would be the best approach to show the lead image (in listings etc)
Use BeautifulSoap to search for first image and somehow add it (to (Lead) Image field) and remove it from (body) text field
use first image as lead image
If I use approach 1, I assume I will have 'double up with blob files', if I could avoid that it would be good
An interesting extension of the imagefield could be to use the related pattern to refer to an existing image.
With 1, you can avoid to duplicate the image referring the lead image in the page template. If you want to refer to the lead image as an image in TinyMce, adding your type to image types to TinyMCE control panel (Resource Types -> Image objects) and you should be able to pick up the lead image from the page itself. I've done a litte demo (you can then customize the template to show just the title and richtext):
Thanks.
Does it show the same scale as the "normal" Lead image (I can not test, collective.imagecropping has messed up my local site). I assume I can set the value programically by searching for first image and then find its UUID or something similar (?)
Looking at the code above: you would have to extract the "first image" and create an image object with it, then in the related_image attribute you would store the relationvalue - ergo, whatever the you get from the RelatedItemsFieldWidget in plone.app.z3cform.widget.
I have never tried doing this programmatically.
Edit: ah, looks like you already have the images as separate content objects.
storing the relation value is not the problem, but generating it .
(was too late yesterday, so I did not look into why it errors, and I am not sure if it has something with me pinning versions to get collective.imagecropping to work)
The error comes from here:
<!-- does not work -->
<!--img tal:replace="structure python: scaled_image.tag(css_class='newsImage')" /-->
<!-- works -->
<img src="${large_image/url}">

You're trying to create the html tag (using .tag) of a scaled image. That image scale does not exist yet. In the template, I see: scale='tile_highlight' hardcoded. Possibly a shortcut/oversight on my part? edit: try replacing that scale with one that exists on your system.
for later reference, it looks like related image can be set like this:
if images:
img_link = images['src']
if img_link:
#import pdb; pdb.set_trace()
#find 'resloveuid" in url, since all images has unique ids here, they can be found without 'finding them by path' (api.content.get(path='/some/path/image.jpg').
image_uid=img_link.split("/")[-1]
#find catalog object
image_brain = app.testsite.portal_catalog(UID=image_uid)[0]
initids = getUtility(IIntIds)
braini = initids.getId(image_brain.getObject())
obj.related_image = RelationValue( braini )
