我编辑时，我的Django网站没有显示任何表单
我正在使用Django构建网站。 而对于某些原因，使用所有表格的词典根本没有显示..
单击“编辑”按钮时，模式显示时没有表单...
forms.server_id需要包含使用server_id的所有表单... 我编辑时用来显示以前数据的server_id。
但出于某种原因，它根本不显示任何形式......

1 个答案:
答案 0 :(得分：1)
这：
{% with server.id as server_id %}
{# ... #}
{{ forms.server_id.as_p }}
无法正常工作 - 它会查找forms["server_id"]（=＆gt;使用文字字符串"server_id"作为键）。您需要一个自定义模板过滤器such as the one described here。正如丹尼尔罗斯曼在评论中正确提到的那样，你也必须将server应该传递给模板的上下文。
另请注意，您将在NameError中获得HomeView.post - 您复制粘贴的部分代码填写在您的posts字典中，但不包括实现它的部分。你应该把它考虑在内而不是复制粘贴。
