Django1.4- assertQuerysetEqual -如何使用方法
提问于 2012-07-23 18:41:56
我想知道TestCase.assertQuerysetEqual方法是如何工作的。我尝试了不同的方法，每种方法都会给我带来另一条错误消息。
#create a backup of all records in the tree
tree_record_backup = list(Tree.objects.all())
#do some updates on another table, which should not affect the tree table if everything goes wrong
#check if list of tree records did not changed
tree_record_qs = Tree.objects.all()
#Number1:
self.assertQuerysetEqual(tree_record_qs,[repr(tree_record_backup)])
#Number2:
self.assertQuerysetEqual(tree_record_qs,tree_record_backup)Number1的错误消息：
First list contains 21 additional elements.
First extra element 1:
node.pk: 2 - node: node2 - pk: 2 - level: 0 - ancestor: 2数字2的错误消息：
AssertionError: Lists differ: ['<Tree: node.pk: 1 - node: ro... != [<Tree: node.pk: 1 - node: roo...
First differing element 0:
<Tree: node.pk: 1 - node: root - pk: 1 - level: 0 - ancestor: 1>
node.pk: 1 - node: root - pk: 1 - level: 0 - ancestor: 1感谢您对如何正确使用assertQuerysetEqual方法的提示。

试试这个：
self.assertQuerysetEqual(
tree_record_qs,
[repr(r) for r in tree_record_backup]
)这有点奇怪，而且没有文档记录；但是，这对你来说应该是有效的。
