imagefield

问题 Hi I'm having a problem about referring to uploaded images in HTML. I'm using ImageField to save profile pictures : picture = models.ImageField(upload_to='stories/static/stories/profile_images/', blank=True) As you can see, It'll upload to <App folder>/static/stories/profile_images/ Then I refer it in HTML like this : <div class="profilepic" style="background-image: url('/{{ x.writer.picture }}');"></div> Which directs to ROOT/stories/static/stories/profile_images/.jpg Instead of ROOT/static

问题 I am looking for a way to rename files that are uploaded by users through a filefield. For example, rename user profile photos using uniqid . I found a good solution for D6 at "Drupal 6: How to Change Filename on Upload" but can't find anything for D7. Another option is to use File (Field) Paths, but: The module causes warnings on my setup. Seems to be a bit of an overkill to install a general module for a very specific purpose. 回答1: You can change every file upload by hook_file_presave as

问题 I have added an image field to content type "Basic Page" and using the "Manage Displays" option have it displayed at the top of the page. However there is no styling on the image and I can't for the life of me figure out how I add a class to the image so that I can add styles. 回答1: If you're using CCK there's almost certainly a class already associated with the image (or at least a class on a div that wraps it). CCK wraps just about everything in a class. Try right clicking the image and

问题 I've been going around in circles for hours with this. I have a UserProfile model with profile_pic ImageField. I saved the user photo and now I want to display it, but nothing works. I went through docs, SO, google, with no result. I uploaded a photo, and I can see that the url was saved in the database. This is what I have: # models.py class UserProfile(models.Model): ... title = models.CharField() about_me = models.CharField() profile_pic = models.ImageField(upload_to=content_file_name,

问题 I'm having a very particular performance problem at work! In the system we're using there's a table that holds information about the current workflow process. One of the fields holds a spreadsheet that contains metadata about the process (don't ask me why!! and NO I CAN'T CHANGE IT!!) The problem is that this spreadsheet is stored in an IMAGE field in an SQL Server 2005 (within a database set with SQL 2000 compatibility).
