Django: Displaying formset errors correctly

阅读更多关于 Django: Displaying formset errors correctly

问题 I have an inline formset for a model, which has a unique_together constraint. And so, when I input data, which doesn't fulfill this constraint, it displays: __all__Please correct the duplicate values below. The code, which does this is: {% for error in formset.errors %} {{ error }}<br/> {% endfor %} I don't much like the __all__ at the beginning of the error and it is quite clearly the dictionary key, so I tried: {% for key, error in formset.errors %} {{ key }}: {{ error }}<br/> {% endfor %}

webapp2, Jinja2: how to cut large html file into multiple html files

阅读更多关于 webapp2, Jinja2: how to cut large html file into multiple html files

When I blog, I like to separate each blog-post into its own .html file (is that ok?) This prevents the file getting too big, and makes it easy to go back and edit a previously written blog post if need be. Occasionally the blog post will contain css/js/ajax/template variables. But on my website, I like all the blog posts on one page (so I can scroll through them all, instead of going to a separate page for each post) Here is an html file that contains two blog posts: {% extends "base.html" %} {% block blog_posts %}  <li><a href="#post2"
