imagefield

问题 I'm not seeing much documentation on this. I'm trying to get an image uploaded onto server from a URL. Ideally I'd like to make things simple but I'm in two minds as to whether using an ImageField is the best way or simpler to simply store the file on the server and display it as a static file. I'm not uploading anyfiles so I need to fetch them in. Can anyone suggest any decent code examples before I try and re-invent the wheel? Given an URL say http://www.xyx.com/image.jpg, I'd like to

问题 I am using shared host with virtualenv to run Django Things run well, however, I can not use ImageField because gcc can not run, and I can not install Pillow.

Now, when I try to show the avatar, I am trying this way, but it doesn't show anything. <img src="media/{{ user.employee.avatar.url }}" alt=""> If I just output user.employee.avatar.url, I get: 'media

问题 The site I am working on uses many content types and almost all of them use one or more image fields. Image fields are not shared between content types, so there is a big number of them. What I need is to get the first image field from a node, assuming there are more image fields linked to a node and without knowing the name of any of these fields. The first one is considered to be the one with a lower weight . 回答1: This should build you an array of the "lightest" imagefield per content type.

问题 Can I set make a Wagtail ImageField only accept images of of certain dimensions ? 回答1: Don't know if it's possible, but you can do something like this to restrict uploading images of large sizes: from wagtail.wagtailadmin.forms import WagtailAdminPageForm class BlogPageForm(WagtailAdminPageForm): def clean(self): cleaned_data = super().clean() if (cleaned_data.get('image') and somehow_check_if_img_to_large(): self.add_error('image', 'Error! image is to large!') return cleaned_data class
